2025-06-17 18:01:34The banking giant is exploring an expansion of its blockchain services, focusing on digital payments and currencies.
JPMorgan Chase has filed a new trademark application for the name “JPMD.” The filing was submitted on June 15 to the United States Patent and Trademark Office (USPTO).
The application, filed by JPMorgan Chase Bank, N.A., covers a broad range of services related to digital assets and blockchain technology. These include the issuance of digital currencies, electronic payment processing, and financial custody services — all of which suggest a possible new stablecoin initiative for JPMorgan.
Experience with JPM Coin
This move wouldn’t be JPMorgan’s first foray into blockchain-based finance. The bank already operates JPM Coin, a dollar-pegged stablecoin used to enable instant transactions between institutional clients. The token runs on Quorum, a private blockchain network developed in-house by JPMorgan and based on Ethereum’s technology.
The registration of the JPMD trademark comes as JPMorgan and other major U.S. banks are considering a collaborative stablecoin project through their jointly owned entities: Early Warning Services and The Clearing House.
Similarly, corporations like Walmart and Amazon are mulling the creation of their own stablecoins.

2025-06-17 17:37:05O protocolo Matrix é um sistema de comunicação descentralizado de código aberto que fornece uma plataforma para mensageiros descentralizados. O Element foi lançado em 2014 como uma implementação do protocolo Matrix, originalmente conhecido como Riot.im , A ideia do Element nasceu quando Matthew Hodgson e Amandine Le Pape, dois desenvolvedores de software, decidiram criar uma plataforma de comunicação aberta e segura, que permitisse aos usuários terem total controle sobre suas informações. Eles acreditavam que a internet deveria ser um lugar onde as pessoas pudessem se comunicar livremente, sem se preocupar com a privacidade de suas informações.
O Element é um aplicativo de chat gratuito e de código aberto disponível em várias plataformas, incluindo desktop, web e aplicativos móveis. Ele oferece criptografia de ponta a ponta, o que significa que as mensagens são protegidas e só podem ser lidas pelo remetente e pelo destinatário. Além disso, o Element é descentralizado, o que significa que ele não é controlado por uma única entidade, mas sim por uma rede global de servidores.
O Element é amplamente utilizado por indivíduos e empresas que desejam ter uma comunicação segura e privada. É frequentemente usado por equipes de projetos, organizações sem fins lucrativos e grupos ativistas que precisam compartilhar informações confidenciais e se comunicar de forma segura. O Element também é conhecido por seu recurso de salas públicas, que permite que os usuários se juntem a grupos de discussão sobre vários tópicos de interesse.
Uma das principais vantagens do Element é sua arquitetura descentralizada. Ao contrário das plataformas de mensagens convencionais que centralizam os dados em seus próprios servidores, o Element utiliza uma rede descentralizada, distribuindo as informações em diversos servidores espalhados pelo mundo. Isso significa que os dados dos usuários são menos suscetíveis a ataques cibernéticos e invasões, já que não são centralizados em um único ponto vulnerável.
Para usar o Element, normalmente os usuários precisam se registrar em um servidor Matrix. Existem várias opções disponíveis, incluindo servidores públicos e privados. No entanto, outra opção é criar um servidor próprio para usar o Element.
O Element também utiliza criptografia de ponta a ponta para proteger as mensagens e arquivos trocados entre os usuários. Isso significa que apenas o remetente e o destinatário das mensagens podem ler o conteúdo, garantindo que as informações permaneçam seguras e privadas.
Outra vantagem do Element é sua ampla variedade de recursos, incluindo videochamadas criptografadas, compartilhamento de tela e integração com outros serviços, como calendários e aplicativos de produtividade. Isso torna o Element uma plataforma completa de comunicação e colaboração, adequada para uso pessoal e empresarial.
O Element também é fácil de usar e possui uma interface intuitiva e personalizável. Os usuários podem personalizar a aparência do aplicativo e acessar diferentes configurações e recursos com apenas alguns cliques.

2025-06-17 17:35:10Desde a sua criação em 2008, Bitcoin tem sido visto como um desafio direto ao sistema bancário tradicional. Desenvolvido como uma alternativa descentralizada ao dinheiro fiduciário, Bitcoin oferece uma forma de armazenar e transferir valor sem depender de bancos, governos ou outras instituições financeiras. Essa característica faz com que seja considerado um símbolo de resistência contra um sistema financeiro que, ao longo do tempo, tem sido marcado por crises, manipulações e restrições impostas aos cidadãos.
Crise financeira de 2008 e o nascimento de Bitcoin
Bitcoin surgiu em resposta à crise financeira de 2008, um colapso que revelou as falhas do sistema bancário global. Bancos centrais imprimiram grandes quantidades de dinheiro para resgatar instituições financeiras irresponsáveis, enquanto milhões de pessoas perderam as suas casas, poupanças e empregos. Nesse contexto, Bitcoin foi criado como um sistema financeiro alternativo, onde não existe uma entidade central com o poder de manipular a economia em benefício próprio.
No primeiro bloco da blockchain ou timechain de Bitcoin, Satoshi Nakamoto incluiu a seguinte mensagem:
"The Times 03/Jan/2009 Chancellor on brink of second bailout for banks."
Essa frase, retirada de uma manchete de jornal da época, simboliza a intenção de Bitcoin de oferecer um sistema financeiro fora do controlo dos bancos e dos governos.
Principais razões pelas quais Bitcoin resiste ao sistema bancário
Descentralização: Ao contrário do dinheiro emitido por bancos centrais, Bitcoin não pode ser criado ou controlado por nenhuma entidade específica. A rede de utilizadores valida as transações de forma transparente e independente.
Oferta limitada: Enquanto os bancos centrais podem imprimir dinheiro sem limites, causando inflação e desvalorização da moeda, Bitcoin tem uma oferta fixa de 21 milhões de unidades, tornando-o resistente à depreciação artificial.
Impossibilidade de censura: Bancos podem bloquear contas e impedir transações a qualquer momento. Com Bitcoin, qualquer pessoa pode enviar e receber fundos sem pedir permissão a terceiros.
Autocustódia: Em vez de confiar os seus fundos a um banco, os utilizadores de Bitcoin podem armazenar as suas próprias moedas, sem risco de congelamento de contas ou falências bancárias.
Conflito entre bancos e Bitcoin
Ataques mediáticos: Grandes instituições financeiras frequentemente classificam Bitcoin como arriscado, volátil ou inútil, tentando desincentivar a sua adoção.
Regulação e repressão: Alguns governos, influenciados pelo setor bancário, têm criado restrições ao uso de Bitcoin, dificultando a sua compra e venda.
Criação de alternativas centralizadas: Muitos bancos centrais estão a desenvolver moedas digitais (CBDCs) que mantêm o controlo do dinheiro digital, mas sem oferecer a liberdade e a descentralização de Bitcoin.
Resumindo, o Bitcoin não é apenas uma moeda digital, mas um movimento de resistência contra um sistema financeiro que falhou repetidamente em proteger o cidadão comum. Ao oferecer uma alternativa descentralizada, transparente e resistente à censura, Bitcoin representa a liberdade financeira e desafia o monopólio dos bancos sobre o dinheiro. Enquanto o sistema bancário tradicional continuar a impor restrições e a controlar o fluxo de capital, Bitcoin permanecerá como um símbolo de independência e soberania financeira.

2025-06-17 18:31:38Como si de resolver un crimen se tratase, en este artículo he querido reflexionar sobre el futuro de los pagos en un mundo cada vez más digital, centrándome en la más que probable desaparición del dinero efectivo, con las monedas digitales de bancos centrales (CBDCs) actuando como arma homicida y los bancos centrales como los verdaderos 'asesinos' de este tipo de dinero. Como veis, sería un pésimo novelista, ya que en el primer párrafo ya he revelado toda la trama.
Introducción.
La mayoría de las transacciones realizadas a diario ya son electrónicas y están gestionadas por bancos o empresas tecnológicas, ya sea a través de ventas de comercio electrónico, pagos presenciales con terminales EMV, tarjetas sin contacto o aplicaciones móviles. Estos pagos son fácilmente rastreables, susceptibles de confiscación y sujetos a censura. A pesar de ello, durante las últimas tres décadas se ha intentado desacreditar al otro tipo de dinero que aún se utiliza hoy en día: el efectivo. Gobiernos de todo el mundo han defendido que eliminar el efectivo es necesario para combatir el lavado de dinero, reducir la evasión fiscal y asegurar una mayor estabilidad de la economía.
¿Cuál puede ser la motivación detrás de todo esto? ¿Es posible que, al analizar al candidato destinado a sustituir al efectivo, encontremos una respuesta?
En este artículo me propongo explorar cuál será el formato del dinero del futuro y si las monedas digitales de bancos centrales (CBDC), cuya implementación está siendo investigada e impulsada actualmente por muchos gobiernos, podrían ser las que acaben definitivamente con el efectivo.
Soy consciente de que hay mucho material e información disponible pero para realizar este artículo me he basado en los siguientes papers:
-
The technology of retail central bank digital currency de Raphael Auer y Rainer Boehme
-
Financial Freedom and Privacy in the Post-Cash World de Alex Gladstein
El crímen a resolver.
La víctima.
El dinero en efectivo (la víctima de este crimen) es el medio de pago físico que utilizamos para realizar transacciones, como billetes y monedas. Es emitido y respaldado por un banco central (en Europa, el BCE, y en Estados Unidos, la Fed), lo que le otorga valor y aceptación general en una economía. Además, representa una deuda del banco central con quien lo posee: al tener un billete, esencialmente el banco central te debe ese valor, comprometiéndose a respaldarlo.
Tener “una deuda del banco central” en el bolsillo ha permitido, durante décadas, realizar transacciones diarias en todo el mundo sin que el comprador deba revelar información al vendedor. Esto es posible porque el sistema se basa en la confianza de que el vendedor podrá intercambiar ese dinero por bienes y servicios en el futuro (confianza mutua en su aceptación futura). Al entregar efectivo, la transacción se liquida al instante, sin intermediarios, verificaciones adicionales ni exposición de datos sensibles como nombres, direcciones o información financiera, lo que facilita el comercio incluso entre desconocidos.
Como en cualquier serie de asesinatos, el detective debe conocer todos los detalles posibles de la víctima para elaborar el perfil del asesino y determinar el móvil del crimen. Siguiendo esta lógica, a continuación presento un conjunto de características del dinero en efectivo que podrían haberle generado "enemigos":
-
Resistente a la censura: El efectivo se intercambia directamente entre dos partes sin necesidad de intermediarios (bancos, plataformas digitales o gobiernos). Esto significa que ninguna entidad puede bloquear o revertir una transacción hecha en persona.
-
Difícilmente rastreable: Las transacciones en efectivo son anónimas, ya que no requieren identificación ni dejan un rastro digital.
-
Difícilmente confiscable: El efectivo, al ser un activo físico, solo puede ser confiscado mediante posesión física directa.
-
Permite cierto nivel de privacidad: El uso de efectivo preserva la privacidad de las personas, ya que no expone datos personales ni patrones de gasto.
-
Independencia de infraestructuras tecnológicas: El efectivo no depende de redes de comunicación, electricidad, internet o sistemas bancarios. En escenarios de apagones, desastres naturales o fallos tecnológicos, el efectivo sigue siendo funcional.
-
Aceptación universal sin intermediarios: El efectivo es aceptado prácticamente en cualquier lugar, sin necesidad de cuentas, dispositivos o aplicaciones.
El arma.
En las series de asesinatos o crímenes en general, hay 3 aspectos clave para resolver un caso y estos son el móvil (es la razón detrás del crimen), la oportunidad(posibilidad real que tuvo el sospechoso para cometer el crimen) y los medios disponibles (capacidad física, técnica o arma para llevar a cabo el crimen). En el crimen a resolver en este artículo he creído conveniente empezar por este último y por tanto como buen amante de los avances tecnológicos, he pedido a chatpgt que me defina una CBDC. Su respuesta debajo:
Una CBDC (Central Bank Digital Currency) o Moneda Digital de Banco Central es una forma de dinero digital emitida y respaldada directamente por el banco central de un país (o países). Es similar al dinero en efectivo (como los billetes y monedas) pero existe únicamente en formato digital.
En resumen, una CBDC es dinero digital seguro, accesible y regulado, diseñado para modernizar los sistemas financieros y facilitar los pagos digitales en la economía. 😊💸
Sin embargo, y muy a mi pesar..., hay un par de puntos que no me han convencido (imagino que sabréis cuáles pero por si acaso, los he marcado en negrita). Por ello, he decidido buscarme las habichuelas por mi cuenta y he encontrado este paper, que creo que puede ser de ayuda: “Central Bank Digital Currencies” del Committee on Payments and Market Infrastructures del Bank for International Settlements. Según se indica en dicho paper;
Establecer una definición precisa de la Central Bank Digital Currency (CBDC) resulta complejo, ya que el concepto abarca diversas ideas y posibilidades. No obstante, su característica esencial es que se trata de una forma de dinero digital emitida directamente por el banco central (una obligación del banco central, denominada en una unidad de cuenta existente) que funciona como medio de intercambio y depósito de valor, y está destinada al público general. Esta característica la distingue del dinero digital utilizado por los bancos comerciales, como las reservas o cuentas de liquidación mantenidas en el banco central.
Llegados aquí, he vuelto a preguntar a chatgpt cuál podría ser el motivo u objetivopara que los bancos centrales estén tan interesados por las CBDCs. Su respuesta, como en el caso anterior, tampoco me ha acabado de convencer:
El Banco Central Europeo busca crear una CBDC, conocida como Euro Digital, con varios objetivos clave; en primer lugar, busca aumentar la inclusión financiera al ofrecer una forma de dinero digital segura y gratuita, accesible para toda la población. Otro objetivo es reforzar la estabilidad financiera, proporcionando una alternativa segura al dinero depositado en bancos privados. Por último, el BCE aspira a promover la innovación en servicios financieros y facilitar pagos transfronterizos más rápidos y eficientes. En conjunto, el Euro Digital busca modernizar la economía europea, proteger su sistema financiero y mantener el liderazgo europeo en la era digital.
Así que, una vez más, me toca aplicar el conocido dicho DYOR (Do Your Own Research). A continuación, mi enfoque:
-
Partiendo de la premisa de que muchos objetos utilizados en crímenes no fueron diseñados originalmente para causar daño, sino que tienen múltiples usos, es evidente que ciertos objetos resultan más propensos a ser utilizados con fines dañinos debido a su diseño. Por ejemplo, un cuchillo de caza, con su hoja afilada y puntiaguda, tiene una capacidad de hacer daño superior a la de un cuchillo de punta redonda.
-
De forma análoga, al analizar las diferentes alternativas de diseño de una CBDC, podríamos identificar aquellos elementos que, intencionadamente o no, facilitan ciertos usos indebidos o riesgos asociados y por ende podríamos intuir también las motivaciones de su creador.
Diseñando una CBDC.
En el artículo titulado “The Technology of Retail Central Bank Digital Currency” de Raphael Auer y Rainer Böhme, los autores analizan el desarrollo de una CBDC mediante un enfoque que parte de las necesidades de los consumidores para fundamentar las decisiones de diseño. Para ilustrar este enfoque, introducen la “CBDC Pyramid”, un modelo que organiza jerárquicamente los aspectos clave del diseño de una moneda digital emitida por un banco central:
En el lado izquierdo de la pirámide exponen las necesidades de los consumidores y seis características asociadas que harían útil a una CBDC:
-
Similar al efectivo con funcionalidad peer-to-peer.
-
Pagos en tiempo real.
-
Operaciones resilientes y robustas.
-
Privacidad.
-
Amplia accesibilidad.
-
Capacidad para pagos transfronterizos.
Y en el lado derecho de la pirámide se describen las decisiones de diseño asociadas a cada una de estas características:
-
Reclamaciones indirectas o directas, y ¿qué papel operativo tendrá el banco central?
-
El modelo de centralización (centralizado o descentralizado).
-
Basado en tokens o en balances.
-
Permitir la integración con otras CBDCs.
La tesis sobre la que se construye el paper de Raphael y Rainer se basa en considerar que la principal necesidad del consumidor debe ser poder contar con una CBDC que represente un derecho similar al efectivo y que idealmente sea fácilmente transferible en entornos de transacciones P2P.
A continuación el paper analiza, para cada una de las capas de la pirámide las elecciones disponibles para determinar cuál de ellas es la que acercaría más a una CBDC a las características del cash:
Nivel 1. CBDC directa o indirecta.
A bajo del todo de la pirámide Raphael Auer y Rainer Böhme sitúan la elección de la arquitectura operacional y como se atenderá la demanda del consumidor final. ¿El consumidor "hablará" directamente con el Banco Central y será este quien centralice todo el proceso? ¿o lo hará a través de intermediarios (banca privada)? En cualquiera de los casos, en el paper se asume que solo el banco central podrá emitir la CBCD.
Las principales diferencias en la elección en la base de la pirámide radican en la estructura de los reclamos legales y en los registros mantenidos por el banco central. En el modelo de “CBDC indirecta”, el consumidor tiene un reclamo sobre un intermediario, mientras que el banco central solo lleva un registro de las cuentas mayoristas. En el modelo de “CBDC directa”, la CBDC representa un reclamo directo sobre el banco central, que mantiene un registro de todos los saldos y los actualiza con cada transacción.
Es importante tener en cuenta que los pagos electrónicos deben afrontar interrupciones de conectividad o pagos sin conexión, lo que implica asumir riesgos por parte de los intermediarios y la relación con el cliente, basada en los procesos de Know Your Customer (KYC), permite al intermediario asumir dichos riesgos. Por lo tanto, a menos que un banco central asumiera la responsabilidad del KYC y la debida diligencia del cliente (lo que requeriría una expansión masiva de sus operaciones, muy por encima de sus mandatos actuales), le resultaría difícil asumir un modelo de "CBDC directa".
Nivel 2. Base de datos centralizada o descentralizada.
En el segundo nivel de la pirámide se encuentra la elección de tener un libro mayor centralizado o distribuido.
En un modelo de CBCD directa con base de datos centralizada, las capacidades tecnológicas del banco central deberían ser enormes ya que sería él solo quien procesaría todas las transacciones de todos los ciudadanos (lo que dificulta enormemente su implementación). Además, la principal vulnerabilidad de una arquitectura con un libro mayor centralizado de esta envergadura es la falla del nodo principal.
Por otro lado, actualmente disponer de un libro mayor distribuido (DLT) implica un rendimiento de transacciones menor que las arquitecturas convencionales debido a las dificultades para ejecutar un mecanismo de consenso eficiente y seguro ya que cada actualización del libro mayor debe armonizarse entre los nodos de todas las entidades. Estos modelos podrían ser válidos para jurisdicciones muy pequeñas pero complicado en jurisdicciones más grandes debido al alto número de transacciones que deberían procesar.
Por otro lado, en un modelo de CBCD indirecta ambos enfoques podrían ser factibles.
Nivel 3. Basado en tokens o en balances.
Una vez que se haya elegido la arquitectura y la infraestructura de la CBDC, surge la cuestión de quién tiene la custodia de los fondos y de cómo y a quién se debe otorgar acceso a dichos fondos.
Los activos en moneda digital son fungibles (bienes o activos que pueden intercambiarse entre sí sin que haya una diferencia en su valor o utilidad), por lo que, en principio, pueden tomar la forma de saldos (“acceso basado en cuentas”) o de tokens (“acceso basado en tokens”).
En un sistema de moneda digital basado en saldos (account based access), se debe registrar en algún lugar un número que represente el tamaño de un conjunto de activos, y las transacciones sucesivas deben resultar en cambios en ese número. En este tipo de sistemas, el propietario de los activos debe proporcionar una identificación (derecho basado en la identidad) para acceder al saldo y realizar una transacción, de ahí entre otras, la necesidad del proceso de KYC.
Por el contrario, con los tokens, todo lo que se necesita para realizar una transacción es el conocimiento de las claves criptográficas que los desbloquean. En este tipo de sistemas, los fondos son de quien es capaz de desbloquearlos y las transacciones realizadas no tienen porque estar directamente asociadas a una identidad por lo que es un sistema mucho más parecido al efectivo.
Nivel 4. Integración entre CBDCs.
¿Será posible utilizar la CBDC emitida por el banco central exclusivamente en territorio nacional o también en el extranjero? ¿Estarán dispuestos los bancos centrales a coordinar esfuerzos en el diseño de estas monedas digitales para permitir que los consumidores gestionen múltiples divisas en una sola wallet? De ser así, se facilitaría un comercio internacional más ágil y se eliminaría el vínculo actual entre un pago en el extranjero y la necesidad de realizar una transacción de cambio de divisas (junto con las comisiones asociadas).
En el sistema actual, primero se adquiere moneda nacional, que luego debe ser cambiada por la divisa extranjera, lo que implica costos y demoras. El modelo con pagos transfronterizos integrados permitiría a los consumidores comprar directamente la CBDC del país extranjero antes de realizar sus compras, eliminando así ese paso innecesario e ineficiente y reduciendo los costos asociados al tipo de cambio.
El diseño previsible (mi apuesta personal).
Aquí perdonadme pero voy a ir al grano con mi predicción:
- Creo que la implementación final será el de una CBDC indirecta ofrecida por intermediarios (los bancos privados) con libro mayor centralizado, basada en cuentas en lugar de tokens y con ciertas restricciones en la interoperabilidad entre CBDCs de distintos países.
¿Por qué pienso esto? En primer lugar, como se mencionó anteriormente, una CBDC directa implicaría un cambio significativo en el sistema financiero al transferir gran parte de las responsabilidades de los bancos privados al banco central. En el sistema actual, los bancos privados desempeñan un papel clave en la creación de dinero a través del proceso de concesión de préstamos y la gestión de depósitos. Sin embargo, con una CBDC directa, el banco central sería responsable de emitir dinero digital directamente a los ciudadanos, lo que reduciría drásticamente la necesidad de que los bancos privados gestionen depósitos minoristas.
Esto no solo limitaría su capacidad de crear dinero a través del crédito, sino que también afectaría su modelo de negocio, ya que se reducirían sus fuentes tradicionales de ingresos. Además, podría disminuir su relevancia en el sistema financiero, dejándolos casi fuera de la ecuación en cuanto a la emisión de dinero.
Por otro lado, considero que el modelo con libro mayor centralizado se impondrá principalmente por dos razones: las limitaciones actuales en cuanto a la capacidad de procesamiento de los sistemas distribuidos (DLT) por las reglas de consenso y el interés de los estados en mantener sus capacidades de monitoreo financiero.
En cuanto a la elección entre un sistema basado en tokens o en balances, es importante destacar que, dado que las transacciones en un sistema basado en tokens no están directamente vinculadas a una identidad, resulta más complejo utilizar una CBDC como herramienta de vigilancia o perfilado por parte del banco central o los intermediarios financieros. Este enfoque preserva en mayor medida la privacidad de los usuarios, alineándose con principios similares a los del efectivo digital.
Por tanto, es altamente probable que tanto el Banco Central Europeo como la Reserva Federal opten por un sistema vinculado a una identidad, ya que, además de facilitar el cumplimiento normativo en materia de prevención de delitos financieros, guarda mayor similitud con el modelo de cuentas corrientes tradicional. De hecho, diversos informes, han señalado que la identificación de los usuarios en una CBDC es un factor clave para garantizar la trazabilidad y evitar el anonimato absoluto, lo que refuerza la posibilidad de que el sistema basado en balances sea el elegido.
Finalmente, pienso que facilitar el acceso sencillo a monedas de otros países que se perciben como más seguras podría llevar a una fuga de capitales hacia estas divisas y la ley de Gresham está a mi favor:
La ley de Gresham establece que, cuando en un mercado circulan simultáneamente dos tipos de dinero con el mismo valor nominal pero diferente valor percibido o estabilidad, la “moneda mala” desplaza a la “moneda buena”: los consumidores prefieren conservar la moneda con mayor valor intrínseco como reserva de valor, utilizándola menos en transacciones diarias, lo que eventualmente lleva a su retirada del mercado como medio de pago.
Básicamente esto quiere decir que en el escenario planteado, si los ciudadanos tuvieran acceso directo y fácil a CBDCs de países con economías más estables o con menor inflación, podrían optar por ahorrar en estas monedas más fuertes mientras usan la moneda local para pagos diarios. Esto no solo reduciría la demanda de la moneda nacional, sino que también podría debilitar su estabilidad y aumentar la fuga de capitales.
El móvil.
¿Podrán las personas poseer y controlar su propio dinero y decidir qué hacer con él, o estarán todas sus opciones de pago sujetas a la supervisión y el permiso de intermediarios?
Para ser capaz de contestar a esta pregunta me he basado en el artículo “Retail Central Bank Digital Currency: Motivations, Opportunities, and Mistakes” de Geoffrey Goodell, Hazem Danny Al Nakib y Tomaso Aste que sugiere que los gobiernos buscaran mantener el control sobre su sistema financiero y facilitar la supervisión y regulación de las transacciones a través de las CBDCs y de ahí el diseño con el que las están desarrollando. Dicho esto y aunque en el apartado anterior ya se han podido vislumbrar algunas posibles motivaciones, estas las voy a resumir a continuación:
-
Soberanía monetaria y financiera: Uno de los principales motores detrás de la exploración de las CBDCs son las preocupaciones institucionales sobre los riesgos emergentes para la soberanía monetaria y financiera. Esto es particularmente relevante para los bancos centrales y los gobiernos, que observan cómo el panorama de los pagos evoluciona rápidamente debido a innovaciones tecnológicas y cambios en las preferencias de los consumidores. Además, la creciente facilidad para acceder a divisas extranjeras, especialmente aquellas consideradas más estables o fuertes, está disminuyendo el uso de la moneda local en algunos países. Esto representa un riesgo directo para la soberanía monetaria, ya que reduce la efectividad de las políticas monetarias nacionales.
-
Control total sobre los estímulos económicos: Un sistema de CBDC plenamente operativo podría otorgar a los bancos centrales un control detallado sobre el estímulo fiscal, permitiéndoles distribuir fondos de manera segmentada con solo presionar un botón. En un escenario donde el efectivo físico desapareciera, las CBDC podrían facilitar la aplicación de tasas de interés negativas, obligando a los ciudadanos a pagar una tarifa por mantener ahorros en sus cuentas. Además, este tipo de moneda digital podría proporcionar a los gobiernos la capacidad de confiscar fondos con mayor facilidad, sancionar a disidentes políticos o incluso automatizar multas por infracciones menores, lo que ha suscitado preocupaciones sobre el potencial abuso de estas herramientas. Finalmente, y por si esto fuera poco, existen estudios que exploran la posibilidad de que las CBDCs puedan utilizarse para rastrear y potencialmente restringir o desincentivar ciertas compras con una alta huella de carbono, integrándolas en un sistema de créditos de carbono personales. Un posible escenario podría ser el siguiente:
-
Al intentar comprar gasolina o diésel, la CBDC verifica la huella de carbono acumulada del usuario.
-
Si el usuario ha superado su límite mensual de emisiones, la transacción podría ser rechazada automáticamente o estar sujeta a un recargo adicional por exceder su cuota.
-
Como alternativa, el usuario podría adquirir créditos de carbono de otros ciudadanos que hayan consumido menos, creando así un mercado de intercambio de emisiones a nivel individual.
Esto no debe sorprender a nadie considerando que el sistema Cap and Trade ya se encuentra implementado en la actualidad. Bajo este esquema, empresas con altas emisiones de CO₂ (como aerolíneas, fábricas e industrias de transporte) deben comprar créditos de carbono cuando superan su límite permitido de emisiones. Por tanto el sistema sería el mismo pero aplicado directamente a los ciudadanos.
-
Oportunidades para el sector privado: Lo primero que hay que tener en cuenta es que hoy en día, las compras diarias realizadas a través de aplicaciones móviles o tarjetas de crédito tienen poca semejanza con las compras hechas en efectivo y los usuarios de plataformas como Visa, Apple Pay, WeChat o PayPal intercambian su libertad y privacidad por conveniencia o "usabilidad". En este tipo de transacciones se exige y se comparte información personal en lugar de protegerla. Todo esto nos ha de hacer reflexionar sobre la gran oportunidad que se presenta para el sector privado y en concreto para las "Big Tech" si consiguen monetizar toda la información del consumidor que una moneda tipo CBDC podría proporcionar. No es de extrañar entonces que empresas como Google, Amazon, Stripe o Mastercard sean partners de proyectos de investigación de este tipo de monedas digitales. Como "Data harvesters" experimentados son conscientes del tremendo valor en la creación de perfiles de usuarios.
-
Crimen y evasión fiscal: Como comentamos anteriormente, algunos gobiernos intentan asociar el uso del efectivo con el lavado de dinero y la corrupción, lo que les permite justificar la implementación de las CBDCs como una estrategia para combatir estos problemas. Un ejemplo es el Banco Central de Bangladesh, que busca digitalizar todas las transacciones minoristas para 2027, argumentando que esto mejorará la eficiencia, promoverá la inclusión financiera y reducirá la criminalidad. En Nigeria, el e-Naira fue introducido con el objetivo de facilitar el rastreo de fondos, pero la población respondió con protestas y una baja adopción de la moneda digital.
Conclusiones.
Desde mi punto de vista, es poco probable que las democracias aprendan pronto a diseñar CBDCs que garanticen la privacidad, y aún menos que tengan el incentivo de ofrecerlas a sus ciudadanos. Al fin y al cabo, muchas de las características que atraen tanto a políticos como a banqueros centrales son incompatibles con el dinero anónimo. Por ello, creo que la única alternativa viable para preservar la privacidad financiera que ofrece el efectivo es desarrollar herramientas monetarias resistentes al abuso gubernamental.
Pocas veces se ha expresado este problema con tanta claridad como lo hizo Wei Dai en un correo electrónico enviado en febrero de 1995 a la lista de correo de Cypherpunks donde Dai escribió:
"Nunca ha existido un gobierno que, tarde o temprano, no haya intentado reducir la libertad de sus ciudadanos y obtener más control sobre ellos, y probablemente nunca existirá uno.
Por lo tanto, en lugar de tratar de convencer a nuestro gobierno actual de que no lo intente, desarrollaremos la tecnología que hará imposible que el gobierno tenga éxito.
Los esfuerzos para influir en el gobierno (por ejemplo, a través del lobby y la propaganda) son importantes solo en la medida en que retrasen lo suficiente su intento de represión como para que la tecnología madure y se adopte ampliamente.”

2025-06-17 17:33:02Bitcoin tem vindo a desempenhar um papel cada vez mais relevante em protestos e movimentos sociais em todo o mundo. Graças à sua natureza descentralizada, resistente à censura e independente do controlo governamental, Bitcoin tornou-se uma ferramenta valiosa para ativistas, organizações e cidadãos que lutam contra regimes opressivos ou sistemas financeiros restritivos.
Bitcoin como alternativa ao sistema financeiro tradicional
Nos últimos anos, governos e instituições bancárias têm utilizado restrições financeiras como uma forma de repressão política. Contas bancárias congeladas, doações bloqueadas e limitações a transações são algumas das estratégias utilizadas para enfraquecer movimentos sociais e protestos. Bitcoin oferece uma alternativa, permitindo que fundos sejam transferidos e armazenados sem a interferência de bancos ou governos.
Uma das principais vantagens de Bitcoin nestes contextos é a sua resistência à censura. Enquanto contas bancárias podem ser encerradas e serviços de pagamento centralizados podem ser pressionados a bloquear transações, Bitcoin funciona numa rede descentralizada, onde ninguém pode impedir que um utilizador envie ou receba fundos.
Exemplos do uso do Bitcoin em protestos
Hong Kong (2019-2020): Durante os protestos pró-democracia, ativistas enfrentaram restrições financeiras ao tentarem organizar manifestações e campanhas. Muitos recorreram a Bitcoin para evitar o rastreamento do governo chinês e garantir financiamento para as suas ações.
Canadá (2022): O movimento dos camionistas que protestavam contra restrições governamentais viu as suas contas bancárias congeladas. Como alternativa, doações em Bitcoin foram utilizadas para contornar a repressão financeira.
Bielorrússia (2020): Após as eleições presidenciais contestadas, manifestantes usaram Bitcoin para financiar atividades e ajudar aqueles que perderam os seus empregos devido à repressão estatal.
Nigéria (2020): Durante os protestos contra a brutalidade policial, conhecidos como #EndSARS, doações internacionais para os manifestantes foram bloqueadas. Bitcoin tornou-se um dos principais meios de financiamento do movimento.
Desafios do uso do Bitcoin em movimentos sociais
Educação e acessibilidade: Muitos ainda desconhecem como utilizar Bitcoin de forma segura e eficiente. A falta de conhecimento pode dificultar a sua adoção em larga escala.
Segurança digital: Movimentos sociais muitas vezes operam sob vigilância intensa. Se as medidas de segurança adequadas não forem seguidas, os fundos podem ser comprometidos.
Volatilidade: O preço de Bitcoin pode variar significativamente num curto período, o que pode afetar o valor das doações e dos fundos arrecadados.
Resumindo, o Bitcoin tem demonstrado ser uma ferramenta essencial para a resistência contra a censura financeira e a repressão governamental. Ao permitir que movimentos sociais e ativistas financiem as suas causas sem depender de intermediários, Bitcoin fortalece a luta pela liberdade e pela justiça. No entanto, a adoção eficaz da tecnologia exige conhecimento, segurança e adaptação às suas características únicas. À medida que mais pessoas aprendem a utilizar Bitcoin, o seu papel nos protestos e movimentos sociais continuará a crescer, reforçando a importância da soberania financeira na luta por direitos e liberdades.

2025-06-17 18:01:50MicroStrategy's Debt-Financed Bitcoin Strategy Will Force a Reckoning Within 18 Months - Jessy Gilger
Jessy Gilger from Unchained Capital warned about the sustainability of MicroStrategy's model and its derivatives like MSTY. He predicts that as more companies adopt Bitcoin treasury strategies, "the P&L will matter more as the balance sheet gets commoditized." Within the next 18 months, he expects the current arbitrage opportunities that MicroStrategy exploits will diminish as Bitcoin reaches higher liquidity levels and more competitors enter the space.
His most concerning prediction involves MSTY specifically, which currently offers distributions annualized at 120% - far exceeding the 16-22% he calculates as reasonable from covered call strategies. "If a whale wants out of MSTY in size... they could sell those derivative positions into an illiquid market where there's no bid," potentially causing a 95% collapse similar to what happened with gold mining ETFs during COVID. He advises investors to consider "private pools" for options strategies rather than pooled products where "you're in the pool with everyone else" and subject to forced liquidations.
Pensions Will Drive the Next Major Bitcoin Adoption Wave in 2026-2027 - Adam Back
Adam Back sees institutional adoption accelerating dramatically as pension funds begin allocating to Bitcoin. "The institutional cover of some of the bigger entities that people would reference... you don't get fired for following BlackRock's recommendation," he explained. With BlackRock now suggesting 2% portfolio allocations and the infrastructure finally in place through Blockstream's new Gannett Trust Company, the barriers for institutional adoption are falling rapidly.
Back predicts this will create a "snowball" effect as pension funds realize Bitcoin can help address their massive unfunded liabilities. He noted that financial institutions offering Bitcoin products are "slow movers" with "policies and training materials and guidance that they got to get through," but once activated, the scale will dwarf current retail and ETF flows. The combination of pension fund allocations, continued nation-state adoption, and the mathematical scarcity of Bitcoin leads him to view even $100,000 as "cheap" given where the market is headed.
Traditional Bond Markets Will Collapse as Bitcoin Becomes the Escape Hatch - Sean Bill
Sean Bill sees a massive shift coming as bond markets deteriorate globally. "You peel back the onion. So who benefits from financial repression, right. And inflating your way out of assets," he explained. With Japanese bond yields blowing out and U.S. 30-year yields jumping 10 basis points in a single day, Bill predicts we're witnessing the early stages of a sovereign debt crisis that will drive unprecedented flows into Bitcoin.
He pointed to Japan's MetaPlanet as a preview of what's coming: "The whole bond market of Japan just flowed into a hotel company." As pension funds and institutions realize they can't meet obligations through traditional fixed income, Bitcoin will become the only viable alternative. Bill believes this transition will accelerate once fiduciaries understand Bitcoin's role as "pristine collateral" that can help them "chip away at those unfunded liabilities." His experience getting Santa Clara County's pension into Bitcoin in 2021 showed him firsthand how a 1-3% allocation at $17,000 could have "wiped out the unfunded liability" as Bitcoin approached $100,000.

New Bitcoin Mining Pool Flips Industry Model: "Plebs Eat First" Could Threaten Corporate Dominance
UTXO Management's explosive report forecasts unprecedented institutional demand that could absorb 20% of Bitcoin's circulating supply by 2026. Bitcoin ETFs shattered records with $36.2 billion in year-one inflows, crushing every commodity ETF launch—and they're projected to hit $100 billion annually by 2027.
The real story? ETFs are just the appetizer. Five massive catalysts are converging: wealth platforms eyeing $120 billion from a modest 0.5% allocation across $60 trillion AUM; corporations following MicroStrategy's playbook now holding 803,143 BTC; potential U.S. Strategic Reserve of 1 million BTC; 13 states with active Bitcoin reserve bills; and the rise of BTCfi yield strategies offering 2-15% returns.
The game-changer: these aren't day traders. CFOs, treasurers, and governments are structurally locked buyers seeking BTC-denominated yields, not quick profits. With FASB mark-to-market accounting removing impairment headaches and regulatory clarity accelerating globally, institutions face a stark reality—allocate now or chase exposure at dramatically higher prices.
This isn't another cycle. It's the institutional colonization of Bitcoin.

2025-06-17 17:31:08Milhões de pessoas em todo o mundo ainda não têm acesso a serviços bancários básicos, seja por falta de infraestrutura, requisitos burocráticos ou instabilidade económica nos seus países. Bitcoin surge como uma solução inovadora para este problema, permitindo que qualquer pessoa com acesso à internet tenha controlo sobre o seu dinheiro, sem depender de bancos ou governos. Ao oferecer um sistema financeiro aberto e acessível, Bitcoin torna-se uma ferramenta poderosa para a inclusão financeira global.
O problema da exclusão financeira
Em muitos países em desenvolvimento, grande parte da população não possui conta bancária. Isto pode acontecer por diversas razões, como:
Falta de acesso a bancos: Muitas comunidades, especialmente em áreas rurais, não têm instituições financeiras próximas.
Exigências burocráticas: Alguns bancos exigem documentação específica ou um histórico de crédito que muitas pessoas não conseguem fornecer.
Custos elevados: As taxas bancárias podem ser proibitivas para quem ganha pouco dinheiro.
Instabilidade económica e política: Em países com alta inflação ou governos instáveis, os bancos podem não ser uma opção segura para guardar dinheiro.
Estas dificuldades deixam milhões de pessoas à margem do sistema financeiro, impossibilitadas de poupar, investir ou realizar transações de forma eficiente.
Bitcoin como alternativa
Bitcoin resolve muitos dos problemas da exclusão financeira ao oferecer um sistema acessível e descentralizado. Com Bitcoin, qualquer pessoa com um telemóvel e acesso à internet pode armazenar e transferir dinheiro sem necessidade de um banco. Entre as principais vantagens estão:
Acessibilidade global: Bitcoin pode ser usado em qualquer lugar do mundo, independentemente da localização do utilizador.
Sem necessidade de intermediários: Diferente dos bancos, que impõem taxas e regras, Bitcoin permite transações diretas entre pessoas.
Baixo custo para transferências internacionais: Enviar dinheiro para outro país pode ser caro e demorado com os métodos tradicionais, enquanto Bitcoin oferece uma alternativa mais rápida e acessível.
Proteção contra a inflação: Em países com moedas instáveis, Bitcoin pode ser usado como reserva de valor, protegendo o poder de compra da população.
Casos de uso na inclusão financeira
Bitcoin já tem sido utilizado para promover a inclusão financeira em diversas partes do mundo. Alguns exemplos incluem:
África e América Latina: Em países como Nigéria, Venezuela e Argentina, onde a inflação é elevada e o acesso a dólares é limitado, muitas pessoas usam Bitcoin para preservar o seu dinheiro e realizar transações internacionais.
Remessas internacionais: Trabalhadores que enviam dinheiro para as suas famílias no estrangeiro evitam as elevadas taxas das empresas de transferências tradicionais ao utilizarem Bitcoin.
Microeconomia digital: Pequenos comerciantes e freelancers que não têm acesso a contas bancárias podem receber pagamentos em Bitcoin de forma direta e segura.
Desafios da inclusão financeira com Bitcoin
Apesar das suas vantagens, a adoção de Bitcoin como ferramenta de inclusão financeira ainda enfrenta alguns desafios, tais como:
Acesso à internet: Muitas regiões pobres ainda não têm uma infraestrutura digital adequada.
Educação financeira: Para que mais pessoas utilizem Bitcoin, é necessário maior conhecimento sobre a tecnologia e as melhores práticas de segurança.
Volatilidade do preço: As oscilações de valor podem dificultar o uso de Bitcoin no dia a dia, especialmente em países onde as pessoas vivem com rendimentos instáveis.
Resumindo, o Bitcoin oferece uma solução viável para milhões de pessoas excluídas do sistema financeiro tradicional. Ao proporcionar acesso global, transações baratas e segurança contra a inflação, torna-se um instrumento poderoso para promover a inclusão financeira. No entanto, para que o seu potencial seja totalmente aproveitado, é essencial investir na educação digital e expandir a infraestrutura tecnológica, permitindo que mais pessoas tenham autonomia financeira através de Bitcoin.

2025-06-17 17:29:01Desde a sua criação, Bitcoin tem sido associado à ideia de liberdade financeira e individual. Diferente do dinheiro tradicional, controlado por governos e bancos centrais, Bitcoin permite que qualquer pessoa no mundo transacione e armazene valor sem depender de intermediários. Essa característica torna-se especialmente relevante em contextos de instabilidade económica, censura financeira e falta de acesso ao sistema bancário.
Bitcoin como ferramenta de autonomia financeira
A principal promessa de Bitcoin é devolver às pessoas o controlo sobre o seu próprio dinheiro. No sistema financeiro tradicional, os bancos e governos têm o poder de congelar contas, restringir transações e desvalorizar moedas através da impressão excessiva de dinheiro. Com Bitcoin, cada utilizador tem total posse dos seus fundos, desde que armazene as suas chaves privadas de forma segura. Isso significa que ninguém pode confiscar ou bloquear o acesso ao seu dinheiro.
Além disso, Bitcoin permite transações internacionais rápidas e baratas, sem depender de bancos ou plataformas de pagamento centralizadas. Em países onde as transferências internacionais são burocráticas e caras, Bitcoin representa uma alternativa eficiente e acessível.
Proteção contra a censura e o controlo estatal
Governos e instituições financeiras podem restringir o acesso ao dinheiro por motivos políticos ou económicos. Em regimes autoritários, dissidentes e jornalistas frequentemente enfrentam bloqueios financeiros como forma de repressão. Bitcoin oferece uma solução para esse problema, pois a sua rede descentralizada impede que qualquer entidade tenha controlo total sobre as transações.
Isto já foi demonstrado em diversos casos ao redor do mundo. Em momentos de crise, quando governos impõem restrições a saques bancários ou impõem limites às remessas de dinheiro, Bitcoin tem sido usado para contornar essas barreiras e garantir que as pessoas possam manter a sua liberdade financeira.
Desafios e responsabilidades da liberdade financeira
Embora Bitcoin ofereça mais liberdade individual, também exige maior responsabilidade por parte do utilizador. Diferente de uma conta bancária, onde um cliente pode recuperar o acesso à sua conta com um simples pedido, em Bitcoin a posse das chaves privadas é essencial. Se um utilizador perde as suas chaves, perde o acesso aos seus fundos para sempre.
Além disso, a volatilidade do preço de Bitcoin pode representar um desafio para quem pretende utilizá-lo como reserva de valor no curto prazo. No entanto, essa característica é compensada pelo seu modelo deflacionário, que protege a poupança a longo prazo contra a desvalorização causada pela inflação das moedas fiduciárias.
Resumindo, o Bitcoin representa uma revolução na forma como as pessoas gerem e protegem o seu dinheiro. Ao permitir transações livres de intermediários e resistir à censura financeira, Bitcoin fortalece a liberdade individual e oferece uma alternativa viável a sistemas financeiros centralizados e controlados por governos. No entanto, essa liberdade vem acompanhada da necessidade de maior responsabilidade, uma vez que cada utilizador é o único responsável pela segurança dos seus fundos. Para aqueles que valorizam a soberania financeira, Bitcoin é uma ferramenta poderosa que pode redefinir o conceito de dinheiro e autonomia pessoal no mundo moderno.

2025-06-17 17:01:31Desde a sua criação, Bitcoin tem sido alvo de debates sobre a sua utilização em atividades ilícitas. muitos críticos afirmam que Bitcoin facilita crimes como lavagem de dinheiro e financiamento de atividades ilegais, devido à sua natureza descentralizada e à possibilidade de realizar transações sem intermediários. no entanto, a realidade é mais complexa e muitas dessas alegações são exageradas ou baseadas em mitos. na verdade, a maioria das transações com Bitcoin são legítimas e até mais rastreáveis do que muitos imaginam.
O mito: Bitcoin é a principal moeda para criminosos
Um dos maiores mitos sobre Bitcoin é a ideia de que ele é amplamente utilizado por criminosos devido ao seu suposto anonimato. este argumento tornou-se popular principalmente devido a casos como o da Silk Road, um mercado negro online desmantelado pelas autoridades em 2013, onde Bitcoin era usado para transações ilegais. no entanto, os dados mais recentes mostram que apenas uma pequena fração das transações em Bitcoin está relacionada com atividades ilícitas.
Além disso, ao contrário do dinheiro em espécie, que é quase impossível de rastrear, todas as transações de Bitcoin são registadas publicamente na blockchain ou timechain. isto significa que qualquer pagamento feito com Bitcoin pode ser analisado e seguido, tornando mais difícil esconder transações suspeitas a longo prazo.
A realidade: Bitcoin é transparente e rastreável
Ao contrário do que muitos pensam, Bitcoin não é completamente anónimo, mas sim pseudónimo. todas as transações ficam registadas na blockchain ou timechain, permitindo que autoridades e analistas de dados consigam seguir os fluxos de dinheiro com precisão. várias empresas especializadas em análise forense de blockchain ou timechain já ajudaram a identificar e desmantelar redes criminosas que tentavam utilizar Bitcoin para fins ilícitos.
Governos e autoridades, como o FBI e a Europol, têm utilizado esta característica para combater crimes financeiros. na prática, criminosos que tentam usar Bitcoin acabam frequentemente por ser apanhados devido à transparência do sistema. por isso, a ideia de que Bitcoin é um refúgio seguro para criminosos não corresponde à realidade.
O uso ilícito de moedas fiduciárias é muito maior
Se compararmos Bitcoin com as moedas fiduciárias tradicionais, como o euro ou o dólar, percebemos que estas são muito mais utilizadas para atividades ilícitas. segundo relatórios de organizações internacionais, a lavagem de dinheiro e o financiamento de crimes organizados ocorrem predominantemente através de bancos, empresas fictícias e dinheiro em espécie.
Por exemplo, em escândalos financeiros globais, como o Panama Papers e o caso do banco HSBC envolvido em lavagem de dinheiro para cartéis, os meios tradicionais foram os preferidos para esconder fortunas ilegais. apesar disso, Bitcoin continua a ser injustamente associado ao crime, enquanto os verdadeiros mecanismos de financiamento ilícito continuam a operar dentro do sistema financeiro convencional.
Resumindo, o mito de que Bitcoin é um meio privilegiado para atividades ilícitas tem sido amplamente desmentido por dados e investigações. apesar de alguns criminosos terem tentado usá-lo no passado, a realidade é que Bitcoin é um sistema financeiro mais transparente e rastreável do que o dinheiro tradicional. a grande maioria das suas transações é legítima e, à medida que a adoção cresce, Bitcoin continua a provar o seu valor como um meio seguro e descentralizado para transações financeiras.

2025-06-17 16:31:03O Bitcoin tem revolucionado a forma como as pessoas realizam transações financeiras em todo o mundo. Sendo uma moeda digital descentralizada, oferece novas oportunidades para pagamentos no comércio eletrónico e transferências internacionais de dinheiro. A sua rapidez, segurança e baixos custos tornam-no uma alternativa eficiente aos métodos tradicionais, eliminando intermediários e facilitando transações globais.
Bitcoin no comércio eletrónico
O comércio eletrónico tem crescido exponencialmente, e o Bitcoin surge como uma solução inovadora para pagamentos online. Grandes retalhistas e pequenas empresas estão a começar a aceitar Bitcoin como forma de pagamento, oferecendo benefícios tanto para os comerciantes como para os consumidores.
Vantagens do Bitcoin para o comércio eletrónico:
Baixas taxas de transação: ao contrário dos cartões de crédito e plataformas de pagamento que cobram taxas elevadas, as transações em Bitcoin apresentam, geralmente, custos mais reduzidos. Isto beneficia os comerciantes, que podem diminuir despesas e oferecer preços mais competitivos aos clientes.
Eliminação de chargebacks: no sistema tradicional, os chargebacks (reembolsos forçados pelos bancos ou operadoras de cartão) representam uma preocupação para os lojistas. Como as transações em Bitcoin são irreversíveis, os comerciantes evitam fraudes e disputas.
Acesso global: qualquer pessoa com acesso à Internet pode pagar com Bitcoin, independentemente da sua localização. Isto permite às empresas expandirem o seu mercado internacionalmente, sem depender de bancos ou sistemas de pagamento locais.
Privacidade e segurança: as transações em Bitcoin protegem a identidade do utilizador, oferecendo maior privacidade em comparação com pagamentos através de cartão de crédito ou transferências bancárias. Além disso, como não há necessidade de partilhar dados pessoais, o risco de roubo de informações é reduzido.
Desafios do Uso do Bitcoin no Comércio Eletrónico:
Volatilidade: o preço do Bitcoin pode oscilar rapidamente, o que dificulta a fixação de preços para produtos e serviços. No entanto, alguns comerciantes utilizam serviços de pagamento que convertem automaticamente Bitcoin em moeda fiduciária, minimizando esse risco.
Adoção limitada: apesar do crescimento, a aceitação do Bitcoin ainda não é universal. Muitas lojas e plataformas populares ainda não o adotaram, o que pode dificultar a sua utilização em compras diárias.
Tempo de confirmação: embora o Bitcoin seja mais rápido do que as transferências bancárias tradicionais, o tempo de confirmação pode variar consoante a taxa de rede paga. Algumas soluções, como a Lightning Network, estão a ser desenvolvidas para tornar os pagamentos instantâneos.
Bitcoin na remessa de dinheiro
O envio de dinheiro para o estrangeiro sempre foi um processo burocrático, dispendioso e demorado. Serviços tradicionais, como os bancos e empresas de transferência de dinheiro, cobram taxas elevadas e podem demorar dias a concluir uma transação. O Bitcoin, por outro lado, oferece uma alternativa eficiente para remessas globais, permitindo que qualquer pessoa envie e receba dinheiro de forma rápida e económica.
Benefícios do Bitcoin para remessas:
Custos reduzidos: enquanto os bancos e empresas como a Western Union cobram elevadas taxas para transferências internacionais, o Bitcoin permite o envio de dinheiro com custos mínimos, independentemente do montante ou do destino.
Velocidade nas transações: as transferências bancárias internacionais podem demorar vários dias a serem concluídas, especialmente em países com uma infraestrutura financeira limitada. Com o Bitcoin, o dinheiro pode ser enviado para qualquer parte do mundo em poucos minutos ou horas.
Acessibilidade global: em regiões onde o sistema bancário é restrito ou ineficiente, o Bitcoin possibilita que as pessoas recebam dinheiro sem depender de bancos. Isto é particularmente útil em países em desenvolvimento, onde as remessas internacionais são uma fonte essencial de rendimento.
Independência de intermediários: o Bitcoin opera de forma descentralizada, sem necessidade de recorrer a bancos ou empresas de transferência. Isto significa que as pessoas podem enviar dinheiro diretamente para amigos e familiares sem intermediários.
Desafios das remessas com Bitcoin:
Conversão para moeda local: apesar de o Bitcoin poder ser recebido instantaneamente, muitas pessoas ainda precisam de convertê-lo em moeda local para o utilizar. Isso pode envolver custos adicionais e depender da disponibilidade de serviços de câmbio.
Adoção e conhecimento: nem todos compreendem o funcionamento do Bitcoin, o que pode dificultar a sua adoção generalizada para remessas. No entanto, a crescente educação financeira sobre o tema pode ajudar a ultrapassar essa barreira.
Regulamentação e restrições: alguns governos impõem restrições ao uso do Bitcoin, tornando as remessas mais complicadas. A evolução das regulamentações pode afetar a facilidade de uso em determinados países.
Resumindo, o Bitcoin está a transformar o comércio eletrónico e as remessas de dinheiro em todo o mundo. A sua capacidade de eliminar intermediários, reduzir custos e oferecer pagamentos rápidos e seguros torna-o uma alternativa viável aos sistemas financeiros tradicionais.
No comércio eletrónico, proporciona benefícios para lojistas e consumidores, reduzindo taxas e melhorando a privacidade. No setor das remessas, facilita a transferência de dinheiro para qualquer parte do mundo, especialmente para aqueles que vivem em países com sistemas bancários pouco eficientes.
Apesar dos desafios, a adoção do Bitcoin continua a crescer, impulsionada por soluções inovadoras e pelo reconhecimento do seu potencial como meio de pagamento global. À medida que mais empresas e indivíduos aderirem a esta tecnologia, a sua presença no comércio eletrónico e nas remessas internacionais será cada vez mais relevante.

Flash Releases Free Bitcoin Invoicing Tool with No Fees, KYC, or CustodyFlash, a Bitcoin payment platform, just announced it has launched Flash Invoicing, a completely free, non-custodial, and KYC-free Bitcoin invoicing tool. Designed for freelancers, the platform allows users to send professional invoices without platform fees, identity checks, or third party custody.
According to Deel, a crypto payments company for freelancers, Bitcoin is the most used cryptocurrency in the world for payments. Despite this growth, many freelancers continue to use basic methods such as pasting Bitcoin addresses into PDFs or emails. Some rely on custodial platforms that deduct fees or require identity verification, which can affect both earnings and data privacy.
“We’ve seen too many people paste BTC addresses into documents and call it invoicing,” said the CEO of Flash Pierre Corbin. “It’s messy. It’s risky. And it’s time for something better.”
Flash Invoicing Features:
- 0% platform fees: no subscriptions or commission
- Non-custodial: Bitcoin goes straight to the user’s wallet
- No KYC: users maintain full privacy
- Professional output: branded PDFs and secure payment links
- Integrated dashboard: manage payments, clients, and revenue
- Works with Flash ecosystem: including Stores, Donations, Paywalls, and POS
Many Bitcoin invoicing tools charge a percentage per transaction or require a subscription. As a result, freelancers often lose part of their income simply to issue an invoice and receive payment. Flash is aiming to solve this issue.
“Freelancers work hard enough. The last thing they need is a platform skimming off their earnings,” said Corbin. “That’s why we dropped our fee from 1.5% to 0% — and launched the first invoicing tool that’s truly free, without compromising on privacy or control.”
Flash Invoicing allows users to accept Bitcoin payments without relinquishing control, privacy, or revenue. It is integrated with the broader Flash suite, enabling users to manage invoicing alongside features such as setting up stores, receiving donations, or gating premium content.
“As a freelancer myself, I love using the Flash invoicing feature,” stated a freelancer & Flash user. ”It keeps all my clients in one place, allows me to easily edit invoices and track payments. Much more professional than sending a lightning address in the footer of a PDF invoice.”

Os princípios básicos da criptografia.
Quando Júlio César enviou mensagens aos seus generais, ele não confiou nos seus mensageiros. Então ele substituiu cada A em suas mensagens por um D, cada B por um E, e assim por diante através do alfabeto. Somente alguém que conhecesse a regra “shift by 3” poderia decifrar suas mensagens. E assim começamos.
Criptografia e descriptografia.
Os dados que podem ser lidos e compreendidos sem quaisquer medidas especiais são chamados de texto simples ou texto não criptografado. O método de disfarçar o texto simples de forma a ocultar sua substância é chamado de criptografia. Criptografar texto simples resulta em um jargão ilegível chamado texto cifrado. Você usa criptografia para garantir que as informações sejam ocultadas de qualquer pessoa a quem não se destinam, mesmo daqueles que podem ver os dados criptografados. O processo de reverter o texto cifrado ao texto simples original é chamado de descriptografia . A Figura 1-1 ilustra esse processo.
https://image.nostr.build/0e2fcb71ed86a6083e083abbb683f8c103f44a6c6db1aeb2df10ae51ec97ebe5.jpg
Figura 1-1. Criptografia e descriptografia
O que é criptografia?
Criptografia é a ciência que usa a matemática para criptografar e descriptografar dados. A criptografia permite armazenar informações confidenciais ou transmiti-las através de redes inseguras (como a Internet) para que não possam ser lidas por ninguém, exceto pelo destinatário pretendido. Embora a criptografia seja a ciência que protege os dados, a criptoanálise é a ciência que analisa e quebra a comunicação segura. A criptoanálise clássica envolve uma combinação interessante de raciocínio analítico, aplicação de ferramentas matemáticas, descoberta de padrões, paciência, determinação e sorte. Os criptoanalistas também são chamados de atacantes. A criptologia abrange tanto a criptografia quanto a criptoanálise.
Criptografia forte.
"Existem dois tipos de criptografia neste mundo: a criptografia que impedirá a sua irmã mais nova de ler os seus arquivos, e a criptografia que impedirá os principais governos de lerem os seus arquivos. Este livro é sobre o último." --Bruce Schneier, Criptografia Aplicada: Protocolos, Algoritmos e Código Fonte em C. PGP também trata deste último tipo de criptografia. A criptografia pode ser forte ou fraca, conforme explicado acima. A força criptográfica é medida no tempo e nos recursos necessários para recuperar o texto simples. O resultado de uma criptografia forte é um texto cifrado que é muito difícil de decifrar sem a posse da ferramenta de decodificação apropriada. Quão díficil? Dado todo o poder computacional e o tempo disponível de hoje – mesmo um bilhão de computadores fazendo um bilhão de verificações por segundo – não é possível decifrar o resultado de uma criptografia forte antes do fim do universo. Alguém poderia pensar, então, que uma criptografia forte resistiria muito bem até mesmo contra um criptoanalista extremamente determinado. Quem pode realmente dizer? Ninguém provou que a criptografia mais forte disponível hoje resistirá ao poder computacional de amanhã. No entanto, a criptografia forte empregada pelo PGP é a melhor disponível atualmente.
Contudo, a vigilância e o conservadorismo irão protegê-lo melhor do que as alegações de impenetrabilidade.
Como funciona a criptografia?
Um algoritmo criptográfico, ou cifra, é uma função matemática usada no processo de criptografia e descriptografia. Um algoritmo criptográfico funciona em combinação com uma chave – uma palavra, número ou frase – para criptografar o texto simples. O mesmo texto simples é criptografado em texto cifrado diferente com chaves diferentes. A segurança dos dados criptografados depende inteiramente de duas coisas: a força do algoritmo criptográfico e o sigilo da chave. Um algoritmo criptográfico, mais todas as chaves possíveis e todos os protocolos que o fazem funcionar constituem um criptossistema. PGP é um criptossistema.
Criptografia convencional.
Na criptografia convencional, também chamada de criptografia de chave secreta ou de chave simétrica , uma chave é usada tanto para criptografia quanto para descriptografia. O Data Encryption Standard (DES) é um exemplo de criptossistema convencional amplamente empregado pelo Governo Federal. A Figura 1-2 é uma ilustração do processo de criptografia convencional. https://image.nostr.build/328b73ebaff84c949df2560bbbcec4bc3b5e3a5163d5fbb2ec7c7c60488f894c.jpg
Figura 1-2. Criptografia convencional
Cifra de César.
Um exemplo extremamente simples de criptografia convencional é uma cifra de substituição. Uma cifra de substituição substitui uma informação por outra. Isso é feito com mais frequência compensando as letras do alfabeto. Dois exemplos são o Anel Decodificador Secreto do Capitão Meia-Noite, que você pode ter possuído quando era criança, e a cifra de Júlio César. Em ambos os casos, o algoritmo serve para compensar o alfabeto e a chave é o número de caracteres para compensá-lo. Por exemplo, se codificarmos a palavra "SEGREDO" usando o valor chave de César de 3, deslocaremos o alfabeto para que a terceira letra abaixo (D) comece o alfabeto. Então começando com A B C D E F G H I J K L M N O P Q R S T U V W X Y Z e deslizando tudo para cima em 3, você obtém DEFGHIJKLMNOPQRSTUVWXYZABC onde D=A, E=B, F=C e assim por diante. Usando este esquema, o texto simples, "SECRET" é criptografado como "VHFUHW". Para permitir que outra pessoa leia o texto cifrado, você diz a ela que a chave é 3. Obviamente, esta é uma criptografia extremamente fraca para os padrões atuais, mas, ei, funcionou para César e ilustra como funciona a criptografia convencional.
Gerenciamento de chaves e criptografia convencional.
A criptografia convencional tem benefícios. É muito rápido. É especialmente útil para criptografar dados que não vão a lugar nenhum. No entanto, a criptografia convencional por si só como meio de transmissão segura de dados pode ser bastante cara, simplesmente devido à dificuldade de distribuição segura de chaves. Lembre-se de um personagem do seu filme de espionagem favorito: a pessoa com uma pasta trancada e algemada ao pulso. Afinal, o que há na pasta? Provavelmente não é o código de lançamento de mísseis/fórmula de biotoxina/plano de invasão em si. É a chave que irá descriptografar os dados secretos. Para que um remetente e um destinatário se comuniquem com segurança usando criptografia convencional, eles devem chegar a um acordo sobre uma chave e mantê-la secreta entre si. Se estiverem em locais físicos diferentes, devem confiar em um mensageiro, no Bat Phone ou em algum outro meio de comunicação seguro para evitar a divulgação da chave secreta durante a transmissão. Qualquer pessoa que ouvir ou interceptar a chave em trânsito poderá posteriormente ler, modificar e falsificar todas as informações criptografadas ou autenticadas com essa chave. Do DES ao Anel Decodificador Secreto do Capitão Midnight, o problema persistente com a criptografia convencional é a distribuição de chaves: como você leva a chave ao destinatário sem que alguém a intercepte?
Criptografia de chave pública.
Os problemas de distribuição de chaves são resolvidos pela criptografia de chave pública, cujo conceito foi introduzido por Whitfield Diffie e Martin Hellman em 1975. (Há agora evidências de que o Serviço Secreto Britânico a inventou alguns anos antes de Diffie e Hellman, mas a manteve um segredo militar - e não fez nada com isso.
[JH Ellis: The Possibility of Secure Non-Secret Digital Encryption, CESG Report, January 1970]) A criptografia de chave pública é um esquema assimétrico que usa um par de chaves para criptografia: uma chave pública, que criptografa os dados, e uma chave privada ou secreta correspondente para descriptografia. Você publica sua chave pública para o mundo enquanto mantém sua chave privada em segredo. Qualquer pessoa com uma cópia da sua chave pública pode criptografar informações que somente você pode ler. Até mesmo pessoas que você nunca conheceu. É computacionalmente inviável deduzir a chave privada da chave pública. Qualquer pessoa que possua uma chave pública pode criptografar informações, mas não pode descriptografá-las. Somente a pessoa que possui a chave privada correspondente pode descriptografar as informações. https://image.nostr.build/fdb71ae7a4450a523456827bdd509b31f0250f63152cc6f4ba78df290887318b.jpg
Figura 1-3. Criptografia de chave pública O principal benefício da criptografia de chave pública é que ela permite que pessoas que não possuem nenhum acordo de segurança pré-existente troquem mensagens com segurança. A necessidade de remetente e destinatário compartilharem chaves secretas através de algum canal seguro é eliminada; todas as comunicações envolvem apenas chaves públicas e nenhuma chave privada é transmitida ou compartilhada. Alguns exemplos de criptossistemas de chave pública são Elgamal (nomeado em homenagem a seu inventor, Taher Elgamal), RSA (nomeado em homenagem a seus inventores, Ron Rivest, Adi Shamir e Leonard Adleman), Diffie-Hellman (nomeado, você adivinhou, em homenagem a seus inventores). ) e DSA, o algoritmo de assinatura digital (inventado por David Kravitz). Como a criptografia convencional já foi o único meio disponível para transmitir informações secretas, o custo dos canais seguros e da distribuição de chaves relegou a sua utilização apenas àqueles que podiam pagar, como governos e grandes bancos (ou crianças pequenas com anéis descodificadores secretos). A criptografia de chave pública é a revolução tecnológica que fornece criptografia forte para as massas adultas. Lembra do mensageiro com a pasta trancada e algemada ao pulso? A criptografia de chave pública o tira do mercado (provavelmente para seu alívio).
Como funciona o PGP.
O PGP combina alguns dos melhores recursos da criptografia convencional e de chave pública. PGP é um criptossistema híbrido. Quando um usuário criptografa texto simples com PGP, o PGP primeiro compacta o texto simples. A compactação de dados economiza tempo de transmissão do modem e espaço em disco e, mais importante ainda, fortalece a segurança criptográfica. A maioria das técnicas de criptoanálise explora padrões encontrados no texto simples para quebrar a cifra. A compressão reduz esses padrões no texto simples, aumentando assim enormemente a resistência à criptoanálise. (Arquivos que são muito curtos para compactar ou que não são compactados bem não são compactados.) O PGP então cria uma chave de sessão, que é uma chave secreta única. Esta chave é um número aleatório gerado a partir dos movimentos aleatórios do mouse e das teclas digitadas. Esta chave de sessão funciona com um algoritmo de criptografia convencional rápido e muito seguro para criptografar o texto simples; o resultado é texto cifrado. Depois que os dados são criptografados, a chave da sessão é criptografada na chave pública do destinatário. Essa chave de sessão criptografada com chave pública é transmitida junto com o texto cifrado ao destinatário.
Figura 1-4. Como funciona a criptografia PGP A descriptografia funciona ao contrário. A cópia do PGP do destinatário usa sua chave privada para recuperar a chave de sessão temporária, que o PGP usa para descriptografar o texto cifrado criptografado convencionalmente.
Figura 1-5. Como funciona a descriptografia PGP A combinação dos dois métodos de criptografia combina a conveniência da criptografia de chave pública com a velocidade da criptografia convencional. A criptografia convencional é cerca de 1.000 vezes mais rápida que a criptografia de chave pública. A criptografia de chave pública, por sua vez, fornece uma solução para
problemas de distribuição de chaves e transmissão de dados. Usados em conjunto, o desempenho e a distribuição de chaves são melhorados sem qualquer sacrifício na segurança.
Chaves.
Uma chave é um valor que funciona com um algoritmo criptográfico para produzir um texto cifrado específico. As chaves são basicamente números muito, muito, muito grandes. O tamanho da chave é medido em bits; o número que representa uma chave de 1024 bits é enorme. Na criptografia de chave pública, quanto maior a chave, mais seguro é o texto cifrado. No entanto, o tamanho da chave pública e o tamanho da chave secreta da criptografia convencional não têm nenhuma relação. Uma chave convencional de 80 bits tem a força equivalente a uma chave pública de 1.024 bits. Uma chave convencional de 128 bits é equivalente a uma chave pública de 3.000 bits. Novamente, quanto maior a chave, mais segura, mas os algoritmos usados para cada tipo de criptografia são muito diferentes e, portanto, a comparação é como a de maçãs com laranjas. Embora as chaves pública e privada estejam matematicamente relacionadas, é muito difícil derivar a chave privada dada apenas a chave pública; no entanto, derivar a chave privada é sempre possível, desde que haja tempo e capacidade computacional suficientes. Isto torna muito importante escolher chaves do tamanho certo; grande o suficiente para ser seguro, mas pequeno o suficiente para ser aplicado rapidamente. Além disso, você precisa considerar quem pode estar tentando ler seus arquivos, quão determinados eles estão, quanto tempo têm e quais podem ser seus recursos. Chaves maiores serão criptograficamente seguras por um longo período de tempo. Se o que você deseja criptografar precisar ficar oculto por muitos anos, você pode usar uma chave muito grande. Claro, quem sabe quanto tempo levará para determinar sua chave usando os computadores mais rápidos e eficientes de amanhã? Houve um tempo em que uma chave simétrica de 56 bits era considerada extremamente segura. As chaves são armazenadas de forma criptografada. O PGP armazena as chaves em dois arquivos no seu disco rígido; um para chaves públicas e outro para chaves privadas. Esses arquivos são chamados de chaveiros. Ao usar o PGP, você normalmente adicionará as chaves públicas dos seus destinatários ao seu chaveiro público. Suas chaves privadas são armazenadas em seu chaveiro privado. Se você perder seu chaveiro privado, não será possível descriptografar nenhuma informação criptografada nas chaves desse anel.
Assinaturas digitais.
Um grande benefício da criptografia de chave pública é que ela fornece um método para empregar assinaturas digitais. As assinaturas digitais permitem ao destinatário da informação verificar a autenticidade da origem da informação e também verificar se a informação está intacta. Assim, as assinaturas digitais de chave pública fornecem autenticação e integridade de dados. A assinatura digital também proporciona o não repúdio, o que significa que evita que o remetente alegue que não enviou realmente as informações. Esses recursos são tão fundamentais para a criptografia quanto a privacidade, se não mais. Uma assinatura digital tem a mesma finalidade de uma assinatura manuscrita. No entanto, uma assinatura manuscrita é fácil de falsificar. Uma assinatura digital é superior a uma assinatura manuscrita porque é quase impossível de ser falsificada, além de atestar o conteúdo da informação, bem como a identidade do signatário.
Algumas pessoas tendem a usar mais assinaturas do que criptografia. Por exemplo, você pode não se importar se alguém souber que você acabou de depositar US$ 1.000 em sua conta, mas quer ter certeza de que foi o caixa do banco com quem você estava lidando. A maneira básica pela qual as assinaturas digitais são criadas é ilustrada na Figura 1-6 . Em vez de criptografar informações usando a chave pública de outra pessoa, você as criptografa com sua chave privada. Se as informações puderem ser descriptografadas com sua chave pública, elas deverão ter se originado em você.
Figura 1-6. Assinaturas digitais simples
Funções hash.
O sistema descrito acima apresenta alguns problemas. É lento e produz um enorme volume de dados – pelo menos o dobro do tamanho da informação original. Uma melhoria no esquema acima é a adição de uma função hash unidirecional no processo. Uma função hash unidirecional recebe uma entrada de comprimento variável – neste caso, uma mensagem de qualquer comprimento, até mesmo milhares ou milhões de bits – e produz uma saída de comprimento fixo; digamos, 160 bits. A função hash garante que, se a informação for alterada de alguma forma – mesmo que por apenas um bit – seja produzido um valor de saída totalmente diferente. O PGP usa uma função hash criptograficamente forte no texto simples que o usuário está assinando. Isso gera um item de dados de comprimento fixo conhecido como resumo da mensagem. (Novamente, qualquer alteração nas informações resulta em um resumo totalmente diferente.) Então o PGP usa o resumo e a chave privada para criar a “assinatura”. O PGP transmite a assinatura e o texto simples juntos. Ao receber a mensagem, o destinatário utiliza o PGP para recalcular o resumo, verificando assim a assinatura. O PGP pode criptografar o texto simples ou não; assinar texto simples é útil se alguns dos destinatários não estiverem interessados ou não forem capazes de verificar a assinatura. Desde que uma função hash segura seja usada, não há como retirar a assinatura de alguém de um documento e anexá-la a outro, ou alterar uma mensagem assinada de qualquer forma. A menor alteração em um documento assinado causará falha no processo de verificação da assinatura digital.
Figura 1-7. Assinaturas digitais seguras As assinaturas digitais desempenham um papel importante na autenticação e validação de chaves de outros usuários PGP.
Certificados digitais.
Um problema com os criptosistemas de chave pública é que os usuários devem estar constantemente vigilantes para garantir que estão criptografando com a chave da pessoa correta. Num ambiente onde é seguro trocar chaves livremente através de servidores públicos, os ataques man-in-the-middle são uma ameaça potencial. Neste tipo de ataque, alguém publica uma chave falsa com o nome e ID de usuário do destinatário pretendido. Os dados criptografados – e interceptados por – o verdadeiro proprietário desta chave falsa estão agora em mãos erradas. Em um ambiente de chave pública, é vital que você tenha certeza de que a chave pública para a qual você está criptografando os dados é de fato a chave pública do destinatário pretendido e não uma falsificação. Você pode simplesmente criptografar apenas as chaves que foram entregues fisicamente a você. Mas suponha que você precise trocar informações com pessoas que nunca conheceu; como você pode saber se tem a chave correta? Os certificados digitais, ou certs, simplificam a tarefa de estabelecer se uma chave pública realmente pertence ao suposto proprietário. Um certificado é uma forma de credencial. Exemplos podem ser sua carteira de motorista, seu cartão de previdência social ou sua certidão de nascimento. Cada um deles contém algumas informações que identificam você e alguma autorização informando que outra pessoa confirmou sua identidade. Alguns certificados, como o seu passaporte, são uma confirmação importante o suficiente da sua identidade para que você não queira perdê-los, para que ninguém os use para se passar por você.
Um certificado digital são dados que funcionam como um certificado físico. Um certificado digital é uma informação incluída na chave pública de uma pessoa que ajuda outras pessoas a verificar se uma chave é genuína ou válida. Os certificados digitais são usados para impedir tentativas de substituir a chave de uma pessoa por outra.
Um certificado digital consiste em três coisas:
● Uma chave pública.
● Informações do certificado. (Informações de "identidade" sobre o usuário, como nome, ID do usuário e assim por diante.) ● Uma ou mais assinaturas digitais.
O objetivo da assinatura digital em um certificado é afirmar que as informações do certificado foram atestadas por alguma outra pessoa ou entidade. A assinatura digital não atesta a autenticidade do certificado como um todo; ele atesta apenas que as informações de identidade assinadas acompanham ou estão vinculadas à chave pública. Assim, um certificado é basicamente uma chave pública com uma ou duas formas de identificação anexadas, além de um forte selo de aprovação de algum outro indivíduo confiável.
Figura 1-8. Anatomia de um certificado PGP
Distribuição de certificados.
Os certificados são utilizados quando é necessário trocar chaves públicas com outra pessoa. Para pequenos grupos de pessoas que desejam se comunicar com segurança, é fácil trocar manualmente disquetes ou e-mails contendo a chave pública de cada proprietário. Esta é a distribuição manual de chave pública e é prática apenas até certo ponto. Além desse ponto, é necessário implementar sistemas que possam fornecer os mecanismos necessários de segurança, armazenamento e troca para que colegas de trabalho, parceiros de negócios ou estranhos possam se comunicar, se necessário. Eles podem vir na forma de repositórios somente de armazenamento, chamados Servidores de Certificados, ou sistemas mais estruturados que fornecem recursos adicionais de gerenciamento de chaves e são chamados de Infraestruturas de Chave Pública (PKIs).
Servidores de certificados.
Um servidor de certificados, também chamado de servidor certificado ou servidor de chaves, é um banco de dados que permite aos usuários enviar e recuperar certificados digitais. Um servidor certificado geralmente fornece alguns recursos administrativos que permitem que uma empresa mantenha suas políticas de segurança – por exemplo, permitindo que apenas as chaves que atendam a determinados requisitos sejam armazenadas.
Infraestruturas de Chave Pública.
Uma PKI contém os recursos de armazenamento de certificados de um servidor de certificados, mas também fornece recursos de gerenciamento de certificados (a capacidade de emitir, revogar, armazenar, recuperar e confiar em certificados). A principal característica de uma PKI é a introdução do que é conhecido como Autoridade Certificadora,ou CA, que é uma entidade humana — uma pessoa, grupo, departamento, empresa ou outra associação — que uma organização autorizou a emitir certificados para seus usuários de computador. (A função de uma CA é análoga à do Passport Office do governo de um país.) Uma CA cria certificados e os assina digitalmente usando a chave privada da CA. Devido ao seu papel na criação de certificados, a CA é o componente central de uma PKI. Usando a chave pública da CA, qualquer pessoa que queira verificar a autenticidade de um certificado verifica a assinatura digital da CA emissora e, portanto, a integridade do conteúdo do certificado (mais importante ainda, a chave pública e a identidade do titular do certificado).
Formatos de certificado.
Um certificado digital é basicamente uma coleção de informações de identificação vinculadas a uma chave pública e assinadas por um terceiro confiável para provar sua autenticidade. Um certificado digital pode ter vários formatos diferentes.
O PGP reconhece dois formatos de certificado diferentes:
● Certificados PGP ● Certificados X.509 Formato do certificado PGP. Um certificado PGP inclui (mas não está limitado a) as seguintes informações: ● O número da versão do PGP — identifica qual versão do PGP foi usada para criar a chave associada ao certificado. A chave pública do titular do certificado — a parte pública do seu par de chaves, juntamente com o algoritmo da chave: RSA, DH (Diffie-Hellman) ou DSA (Algoritmo de Assinatura Digital).
● As informações do detentor do certificado — consistem em informações de “identidade” sobre o usuário, como seu nome, ID de usuário, fotografia e assim por diante. ● A assinatura digital do proprietário do certificado — também chamada de autoassinatura, é a assinatura que utiliza a chave privada correspondente da chave pública associada ao certificado. ● O período de validade do certificado — a data/hora de início e a data/hora de expiração do certificado; indica quando o certificado irá expirar. ● O algoritmo de criptografia simétrica preferido para a chave — indica o algoritmo de criptografia para o qual o proprietário do certificado prefere que as informações sejam criptografadas. Os algoritmos suportados são CAST, IDEA ou Triple-DES. Você pode pensar em um certificado PGP como uma chave pública com um ou mais rótulos vinculados a ele (veja a Figura 1.9 ). Nessas 'etiquetas' você encontrará informações que identificam o proprietário da chave e uma assinatura do proprietário da chave, que afirma que a chave e a identificação andam juntas. (Essa assinatura específica é chamada de autoassinatura; todo certificado PGP contém uma autoassinatura.) Um aspecto único do formato de certificado PGP é que um único certificado pode conter múltiplas assinaturas. Várias ou muitas pessoas podem assinar o par chave/identificação para atestar a sua própria garantia de que a chave pública pertence definitivamente ao proprietário especificado. Se você procurar em um servidor de certificados público, poderá notar que certos certificados, como o do criador do PGP, Phil Zimmermann, contêm muitas assinaturas. Alguns certificados PGP consistem em uma chave pública com vários rótulos, cada um contendo um meio diferente de identificar o proprietário da chave (por exemplo, o nome do proprietário e a conta de e-mail corporativa, o apelido do proprietário e a conta de e-mail residencial, uma fotografia do proprietário — tudo em um certificado). A lista de assinaturas de cada uma dessas identidades pode ser diferente; as assinaturas atestam a autenticidade de que um dos rótulos pertence à chave pública, e não que todos os rótulos da chave sejam autênticos. (Observe que 'autêntico' está nos olhos de quem vê - assinaturas são opiniões, e diferentes pessoas dedicam diferentes níveis de devida diligência na verificação da autenticidade antes de assinar uma chave.)
Figura 1-9. Um certificado PGP
Formato de certificado X.509.
X.509 é outro formato de certificado muito comum. Todos os certificados X.509 estão em conformidade com o padrão internacional ITU-T X.509; assim (teoricamente) os certificados X.509 criados para um aplicativo podem ser usados por qualquer aplicativo compatível com X.509. Na prática, porém, diferentes empresas criaram suas próprias extensões para certificados X.509, e nem todas funcionam juntas. Um certificado exige que alguém valide que uma chave pública e o nome do proprietário da chave andam juntos. Com os certificados PGP, qualquer pessoa pode desempenhar o papel de validador. Com certificados X.509, o validador é sempre uma Autoridade Certificadora ou alguém designado por uma CA. (Tenha em mente que os certificados PGP também suportam totalmente uma estrutura hierárquica usando uma CA para validar certificados.)
Um certificado X.509 é uma coleção de um conjunto padrão de campos contendo informações sobre um usuário ou dispositivo e sua chave pública correspondente. O padrão X.509 define quais informações vão para o certificado e descreve como codificá-lo (o formato dos dados). Todos os certificados X.509 possuem os seguintes dados:
O número da versão X.509
— identifica qual versão do padrão X.509 se aplica a este certificado, o que afeta quais informações podem ser especificadas nele. A mais atual é a versão 3.
A chave pública do titular do certificado
— a chave pública do titular do certificado, juntamente com um identificador de algoritmo que especifica a qual sistema criptográfico a chave pertence e quaisquer parâmetros de chave associados.
O número de série do certificado
— a entidade (aplicação ou pessoa) que criou o certificado é responsável por atribuir-lhe um número de série único para distingui-lo de outros certificados que emite. Esta informação é usada de diversas maneiras; por exemplo, quando um certificado é revogado, seu número de série é colocado em uma Lista de Revogação de Certificados ou CRL.
O identificador exclusivo do detentor do certificado
— (ou DN — nome distinto). Este nome pretende ser exclusivo na Internet. Este nome pretende ser exclusivo na Internet. Um DN consiste em múltiplas subseções e pode ser parecido com isto: CN=Bob Allen, OU=Divisão Total de Segurança de Rede, O=Network Associates, Inc., C=EUA (Referem-se ao nome comum, à unidade organizacional, à organização e ao país do sujeito .)
O período de validade do certificado
— a data/hora de início e a data/hora de expiração do certificado; indica quando o certificado irá expirar.
O nome exclusivo do emissor do certificado
— o nome exclusivo da entidade que assinou o certificado. Normalmente é uma CA. A utilização do certificado implica confiar na entidade que assinou este certificado. (Observe que em alguns casos, como certificados de CA raiz ou de nível superior , o emissor assina seu próprio certificado.)
A assinatura digital do emitente
— a assinatura utilizando a chave privada da entidade que emitiu o certificado.
O identificador do algoritmo de assinatura
— identifica o algoritmo usado pela CA para assinar o certificado.
Existem muitas diferenças entre um certificado X.509 e um certificado PGP, mas as mais importantes são as seguintes: você pode criar seu próprio certificado PGP;
● você deve solicitar e receber um certificado X.509 de uma autoridade de certificação
● Os certificados X.509 suportam nativamente apenas um único nome para o proprietário da chave
● Os certificados X.509 suportam apenas uma única assinatura digital para atestar a validade da chave
Para obter um certificado X.509, você deve solicitar a uma CA a emissão de um certificado. Você fornece sua chave pública, prova de que possui a chave privada correspondente e algumas informações específicas sobre você. Em seguida, você assina digitalmente as informações e envia o pacote completo – a solicitação de certificado – para a CA. A CA então realiza algumas diligências para verificar se as informações fornecidas estão corretas e, em caso afirmativo, gera o certificado e o devolve.
Você pode pensar em um certificado X.509 como um certificado de papel padrão (semelhante ao que você recebeu ao concluir uma aula de primeiros socorros básicos) com uma chave pública colada nele. Ele contém seu nome e algumas informações sobre você, além da assinatura da pessoa que o emitiu para você.
Figura 1-10. Um certificado X.509 Provavelmente, o uso mais visível dos certificados X.509 atualmente é em navegadores da web.
Validade e confiança Cada usuário em um sistema de chave pública está vulnerável a confundir uma chave falsa (certificado) com uma chave real. Validade é a confiança de que um certificado de chave pública pertence ao seu suposto proprietário. A validade é essencial em um ambiente de chave pública onde você deve estabelecer constantemente se um determinado certificado é autêntico ou não. Depois de ter certeza de que um certificado pertencente a outra pessoa é válido, você pode assinar a cópia em seu chaveiro para atestar que verificou o certificado e que ele é autêntico. Se quiser que outras pessoas saibam que você deu ao certificado seu selo de aprovação, você pode exportar a assinatura para um servidor de certificados para que outras pessoas possam vê-la.
Conforme descrito na seção Infraestruturas de Chave Pública , algumas empresas designam uma ou mais Autoridades de Certificação (CAs) para indicar a validade do certificado. Em uma organização que usa uma PKI com certificados X.509, é função da CA emitir certificados aos usuários — um processo que geralmente envolve responder à solicitação de certificado do usuário. Em uma organização que usa certificados PGP sem PKI, é função da CA verificar a autenticidade de todos os certificados PGP e depois assinar os bons. Basicamente, o objetivo principal de uma CA é vincular uma chave pública às informações de identificação contidas no certificado e, assim, garantir a terceiros que algum cuidado foi tomado para garantir que esta ligação das informações de identificação e da chave seja válida. O CA é o Grand Pooh-bah da validação em uma organização; alguém em quem todos confiam e, em algumas organizações, como aquelas que utilizam uma PKI, nenhum certificado é considerado válido, a menos que tenha sido assinado por uma CA confiável.
Verificando validade.
Uma maneira de estabelecer a validade é passar por algum processo manual. Existem várias maneiras de fazer isso. Você pode exigir que o destinatário pretendido lhe entregue fisicamente uma cópia de sua chave pública. Mas isto é muitas vezes inconveniente e ineficiente. Outra forma é verificar manualmente a impressão digital do certificado. Assim como as impressões digitais de cada ser humano são únicas, a impressão digital de cada certificado PGP é única. A impressão digital é um hash do certificado do usuário e aparece como uma das propriedades do certificado. No PGP, a impressão digital pode aparecer como um número hexadecimal ou uma série das chamadas palavras biométricas, que são foneticamente distintas e são usadas para facilitar um pouco o processo de identificação da impressão digital. Você pode verificar se um certificado é válido ligando para o proprietário da chave (para que você origine a transação) e pedindo ao proprietário que leia a impressão digital de sua chave para você e compare essa impressão digital com aquela que você acredita ser a verdadeira. Isso funciona se você conhece a voz do proprietário, mas como verificar manualmente a identidade de alguém que você não conhece? Algumas pessoas colocam a impressão digital de sua chave em seus cartões de visita exatamente por esse motivo. Outra forma de estabelecer a validade do certificado de alguém é confiar que um terceiro indivíduo passou pelo processo de validação do mesmo. Uma CA, por exemplo, é responsável por garantir que, antes de emitir um certificado, ele ou ela o verifique cuidadosamente para ter certeza de que a parte da chave pública realmente pertence ao suposto proprietário. Qualquer pessoa que confie na CA considerará automaticamente quaisquer certificados assinados pela CA como válidos. Outro aspecto da verificação da validade é garantir que o certificado não foi revogado. Para obter mais informações, consulte a seção Revogação de certificado .
Estabelecendo confiança.
Você valida certificados. Você confia nas pessoas. Mais especificamente, você confia nas pessoas para validar os certificados de outras pessoas. Normalmente, a menos que o proprietário lhe entregue o certificado, você terá que confiar na palavra de outra pessoa de que ele é válido.
Introdutores meta e confiáveis.
Na maioria das situações, as pessoas confiam completamente na CA para estabelecer a validade dos certificados. Isso significa que todos os demais dependem da CA para passar por todo o processo de validação manual. Isso é aceitável até um certo número de usuários ou locais de trabalho e, então, não é possível para a AC manter o mesmo nível de validação de qualidade. Nesse caso, é necessário adicionar outros validadores ao sistema.
Um CA também pode ser um meta- introdutor. Um meta-introdutor confere não apenas validade às chaves, mas também confere a capacidade de confiar nas chaves a outros. Semelhante ao rei que entrega seu selo a seus conselheiros de confiança para que eles possam agir de acordo com sua autoridade, o meta-introdutor permite que outros atuem como introdutores de confiança. Esses introdutores confiáveis podem validar chaves com o mesmo efeito do meta-introdutor. Eles não podem, entretanto, criar novos introdutores confiáveis.
Meta-introdutor e introdutor confiável são termos PGP. Em um ambiente X.509, o meta-introdutor é chamado de Autoridade de Certificação raiz ( CA raiz) e os introdutores confiáveis são Autoridades de Certificação subordinadas . A CA raiz usa a chave privada associada a um tipo de certificado especial denominado certificado CA raiz para assinar certificados. Qualquer certificado assinado pelo certificado CA raiz é visto como válido por qualquer outro certificado assinado pela raiz. Este processo de validação funciona mesmo para certificados assinados por outras CAs no sistema — desde que o certificado da CA raiz tenha assinado o certificado da CA subordinada, qualquer certificado assinado pela CA será considerado válido para outras pessoas dentro da hierarquia. Este processo de verificação de backup por meio do sistema para ver quem assinou cujo certificado é chamado de rastreamento de um caminho de certificação ou cadeia de certificação.
Modelos de confiança.
Em sistemas relativamente fechados, como em uma pequena empresa, é fácil rastrear um caminho de certificação até a CA raiz. No entanto, os usuários muitas vezes precisam se comunicar com pessoas fora do seu ambiente corporativo, incluindo algumas que nunca conheceram, como fornecedores, consumidores, clientes, associados e assim por diante. É difícil estabelecer uma linha de confiança com aqueles em quem sua CA não confia explicitamente. As empresas seguem um ou outro modelo de confiança, que determina como os usuários irão estabelecer a validade do certificado. Existem três modelos diferentes:
Confiança Direta.
Confiança Hierárquica Uma teia de confiança Confiança direta A confiança direta é o modelo de confiança mais simples. Neste modelo, um usuário confia que uma chave é válida porque sabe de onde ela veio. Todos os criptosistemas usam essa forma de confiança de alguma forma. Por exemplo, em navegadores da Web, as chaves raiz da Autoridade de Certificação são diretamente confiáveis porque foram enviadas pelo fabricante. Se houver alguma forma de hierarquia, ela se estenderá a partir desses certificados diretamente confiáveis. No PGP, um usuário que valida as chaves e nunca define outro certificado para ser um introdutor confiável está usando confiança direta.
Figura 1-11. Confiança direta
Confiança Hierárquica.
Em um sistema hierárquico, há vários certificados "raiz" a partir dos quais a confiança se estende. Esses certificados podem certificar eles próprios certificados ou podem certificar certificados que certificam ainda outros certificados em alguma cadeia. Considere isso como uma grande “árvore” de confiança. A validade do certificado "folha" é verificada rastreando desde seu certificador até outros certificadores, até que um certificado raiz diretamente confiável seja encontrado.
Figura 1-12. Confiança hierárquica
Teia de Confiança.
Uma teia de confiança abrange ambos os outros modelos, mas também acrescenta a noção de que a confiança está nos olhos de quem vê (que é a visão do mundo real) e a ideia de que mais informação é melhor. É, portanto, um modelo de confiança cumulativa. Um certificado pode ser confiável diretamente ou confiável em alguma cadeia que remonta a um certificado raiz diretamente confiável (o meta-introdutor) ou por algum grupo de introdutores.
Talvez você já tenha ouvido falar do termo seis graus de separação, que sugere que qualquer pessoa no mundo pode determinar algum vínculo com qualquer outra pessoa no mundo usando seis ou menos outras pessoas como intermediários. Esta é uma teia de introdutores. É também a visão de confiança do PGP. PGP usa assinaturas digitais como forma de introdução. Quando qualquer usuário assina a chave de outro, ele ou ela se torna o introdutor dessa chave. À medida que esse processo avança, ele estabelece uma rede de confiança.
Em um ambiente PGP, qualquer usuário pode atuar como autoridade certificadora. Qualquer usuário PGP pode validar o certificado de chave pública de outro usuário PGP. No entanto, tal certificado só é válido para outro usuário se a parte confiável reconhecer o validador como um introdutor confiável. (Ou seja, você confia na minha opinião de que as chaves dos outros são válidas apenas se você me considerar um apresentador confiável. Caso contrário, minha opinião sobre a validade das outras chaves é discutível.) Armazenados no chaveiro público de cada usuário estão indicadores de
● se o usuário considera ou não uma chave específica válida
● o nível de confiança que o usuário deposita na chave que o proprietário da chave pode servir como certificador das chaves de terceiros
Você indica, na sua cópia da minha chave, se acha que meu julgamento conta. Na verdade, é um sistema de reputação: certas pessoas têm a reputação de fornecer boas assinaturas e as pessoas confiam nelas para atestar a validade de outras chaves.
Níveis de confiança no PGP.
O nível mais alto de confiança em uma chave, a confiança implícita , é a confiança em seu próprio par de chaves. O PGP assume que se você possui a chave privada, você deve confiar nas ações da sua chave pública relacionada. Quaisquer chaves assinadas pela sua chave implicitamente confiável são válidas.
Existem três níveis de confiança que você pode atribuir à chave pública de outra pessoa:
● Confiança total ● Confiança marginal ● Não confiável (ou não confiável)
Para tornar as coisas confusas, também existem três níveis de validade:
● Válido ● Marginalmente válido ● Inválido
Para definir a chave de outra pessoa como um introdutor confiável, você
- Comece com uma chave válida, que seja.
- assinado por você ou
-
assinado por outro apresentador confiável e então
-
Defina o nível de confiança que você acha que o proprietário da chave tem direito.
Por exemplo, suponha que seu chaveiro contenha a chave de Alice. Você validou a chave de Alice e indica isso assinando-a. Você sabe que Alice é uma verdadeira defensora da validação de chaves de outras pessoas. Portanto, você atribui a chave dela com confiança total. Isso faz de Alice uma Autoridade Certificadora. Se Alice assinar a chave de outra pessoa, ela aparecerá como Válida em seu chaveiro. O PGP requer uma assinatura Totalmente confiável ou duas assinaturas Marginalmente confiáveis para estabelecer uma chave como válida. O método do PGP de considerar dois Marginais iguais a um Completo é semelhante a um comerciante que solicita duas formas de identificação. Você pode considerar Alice bastante confiável e também considerar Bob bastante confiável. Qualquer um deles sozinho corre o risco de assinar acidentalmente uma chave falsificada, portanto, você pode não depositar total confiança em nenhum deles. No entanto, as probabilidades de ambos os indivíduos terem assinado a mesma chave falsa são provavelmente pequenas.
Revogação de certificado.
Os certificados só são úteis enquanto são válidos. Não é seguro simplesmente presumir que um certificado é válido para sempre. Na maioria das organizações e em todas as PKIs, os certificados têm uma vida útil restrita. Isso restringe o período em que um sistema fica vulnerável caso ocorra um comprometimento do certificado.
Os certificados são assim criados com um período de validade programado: uma data/hora de início e uma data/hora de expiração. Espera-se que o certificado seja utilizável durante todo o seu período de validade (seu tempo de vida ). Quando o certificado expirar, ele não será mais válido, pois a autenticidade do seu par chave/identificação não estará mais garantida. (O certificado ainda pode ser usado com segurança para reconfirmar informações que foram criptografadas ou assinadas dentro do período de validade – no entanto, ele não deve ser confiável para tarefas criptográficas futuras.)
Existem também situações em que é necessário invalidar um certificado antes da sua data de expiração, como quando o titular do certificado termina o contrato de trabalho com a empresa ou suspeita que a chave privada correspondente do certificado foi comprometida. Isso é chamado de revogação. Um certificado revogado é muito mais suspeito do que um certificado expirado. Os certificados expirados são inutilizáveis, mas não apresentam a mesma ameaça de comprometimento que um certificado revogado. Qualquer pessoa que tenha assinado um certificado pode revogar a sua assinatura no certificado (desde que utilize a mesma chave privada que criou a assinatura). Uma assinatura revogada indica que o signatário não acredita mais que a chave pública e as informações de identificação pertencem uma à outra, ou que a chave pública do certificado (ou a chave privada correspondente) foi comprometida. Uma assinatura revogada deve ter quase tanto peso quanto um certificado revogado. Com certificados X.509, uma assinatura revogada é praticamente igual a um certificado revogado, visto que a única assinatura no certificado é aquela que o tornou válido em primeiro lugar – a assinatura da CA. Os certificados PGP fornecem o recurso adicional de que você pode revogar todo o seu certificado (não apenas as assinaturas nele) se você achar que o certificado foi comprometido. Somente o proprietário do certificado (o detentor da chave privada correspondente) ou alguém que o proprietário do certificado tenha designado como revogador pode revogar um certificado PGP. (Designar um revogador é uma prática útil, pois muitas vezes é a perda da senha da chave privada correspondente do certificado que leva um usuário PGP a revogar seu certificado - uma tarefa que só é possível se alguém tiver acesso à chave privada. ) Somente o emissor do certificado pode revogar um certificado X.509.
Comunicar que um certificado foi revogado.
Quando um certificado é revogado, é importante conscientizar os usuários potenciais do certificado de que ele não é mais válido. Com certificados PGP, a maneira mais comum de comunicar que um certificado foi revogado é publicá-lo em um servidor de certificados para que outras pessoas que desejem se comunicar com você sejam avisadas para não usar essa chave pública. Em um ambiente PKI, a comunicação de certificados revogados é mais comumente obtida por meio de uma estrutura de dados chamada Lista de Revogação de Certificados, ou CRL, que é publicada pela CA. A CRL contém uma lista validada com carimbo de data e hora de todos os certificados revogados e não expirados no sistema. Os certificados revogados permanecem na lista apenas até expirarem e, em seguida, são removidos da lista — isso evita que a lista fique muito longa. A CA distribui a CRL aos usuários em algum intervalo programado regularmente (e potencialmente fora do ciclo, sempre que um certificado é revogado). Teoricamente, isso impedirá que os usuários usem involuntariamente um certificado comprometido. É possível, no entanto, que haja um período de tempo entre as CRLs em que um certificado recentemente comprometido seja usado.
O que é uma senha?
A maioria das pessoas está familiarizada com a restrição de acesso a sistemas de computador por meio de uma senha, que é uma sequência única de caracteres que um usuário digita como código de identificação.
Uma senha longa é uma versão mais longa de uma senha e, em teoria, mais segura. Normalmente composta por várias palavras, uma frase secreta é mais segura contra ataques de dicionário padrão, em que o invasor tenta todas as palavras do dicionário na tentativa de determinar sua senha. As melhores senhas são relativamente longas e complexas e contêm uma combinação de letras maiúsculas e minúsculas, caracteres numéricos e de pontuação. O PGP usa uma senha para criptografar sua chave privada em sua máquina. Sua chave privada é criptografada em seu disco usando um hash de sua senha como chave secreta. Você usa a senha para descriptografar e usar sua chave privada. Uma senha deve ser difícil de esquecer e difícil de ser adivinhada por outras pessoas. Deve ser algo já firmemente enraizado na sua memória de longo prazo, em vez de algo que você invente do zero. Por que? Porque se você esquecer sua senha, você estará sem sorte. Sua chave privada é total e absolutamente inútil sem sua senha e nada pode ser feito a respeito. Lembra-se da citação anterior neste capítulo?
PGP é a criptografia que manterá os principais governos fora dos seus arquivos. Certamente também o manterá fora de seus arquivos. Tenha isso em mente quando decidir alterar sua senha para a piada daquela piada que você nunca consegue lembrar.
Divisão de chave.
Dizem que um segredo não é segredo se for conhecido por mais de uma pessoa. Compartilhar um par de chaves privadas representa um grande problema. Embora não seja uma prática recomendada, às vezes é necessário compartilhar um par de chaves privadas. Chaves de assinatura corporativa, por exemplo, são chaves privadas usadas por uma empresa para assinar – por exemplo – documentos legais, informações pessoais confidenciais ou comunicados de imprensa para autenticar sua origem. Nesse caso, vale a pena que vários membros da empresa tenham acesso à chave privada. No entanto, isto significa que qualquer indivíduo pode agir plenamente em nome da empresa. Nesse caso, é aconselhável dividir a chave entre várias pessoas, de modo que mais de uma ou duas pessoas apresentem um pedaço da chave para reconstituí-la em condições utilizáveis. Se poucas peças da chave estiverem disponíveis, a chave ficará inutilizável. Alguns exemplos são dividir uma chave em três partes e exigir duas delas para reconstituir a chave, ou dividi-la em duas partes e exigir ambas as peças. Se uma conexão de rede segura for usada durante o processo de reconstituição, os acionistas da chave não precisam estar fisicamente presentes para aderirem novamente à chave.

2025-06-17 07:01:11This article was originally published on dev.to by satshacker.
Alright, you’ve built a useful and beautiful website, tool or app. However, monetization isn’t a priority and you’d rather keep the project free, ads-free and accessible?
Accepting donations would be an option, but how? A PayPal button? Stripe? Buymeacoffe? Patreon?
All of these services require a bank account and KYC verification, before you can send and receive donations – not very convenient.
If we only could send value over the internet, with just one click and without the need of a bank account…
Oh, hold on, that’s bitcoin. The decentralized protocol to send value across the globe. Money over TCP/IP.
In this article, we’ll learn how anyone can easily add a payment button or donation widget on a website or app.
Let’s get into it.
Introduction
Bitcoin is digital money that you can send and receive without the need for banks. While bitcoin is extremely secure, it’s not very fast. The maximum transactions per second (TPS) the network can handle is about 7. Obviously that’s not useful for daily payments or microtransactions.
If you’d like to dig deeper into how bitcoin works, a great read is “Mastering Bitcoin” by Andreas Antonopoulos.
Bitcoin vs Lightning
If you’d like to receive bitcoin donations “on-chain” all you need is a bitcoin wallet. You simply display your bitcoin address on your site and that’s it. You can receive donations.
It would look something like this; 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa
Instead of showing the actual bitcoin address, you can also turn it into a QR code.
However, this is not a recommended solution. Using static on-chain addresses has two major downsides. It lowers privacy for you and your donnors and it’s a UTXO disaster because many small incoming transactions could beocme hard to consolidate in the future.
For donations and small transactions, the Lightning Network is the better option. Lightning allows for instant settlement with fees only a fraction of a cent.
Similar to bitcoin, you have the choice between non-custodial and custodial wallets. This means, either you have full control over your money or the wallet provider has.
Option 1: Lightning Address
With the lightning address feature, you an easily receive donations to an email like address.
It looks like this: yourname@wallet.com
Many wallets support lightning addresses and make it easy to create one. Then, you simple add the address to your donation page and you’re ready to receive tips.
You can also add a link link as in lightning:yourname@wallet.com and compatible lightning wallets and browser wallets will detect the address.
Option 2: Lightning Donation Widgets
If you like to take it a step further, you can also create a more enhanced donation checkout flow. Of course you could programm something yourself, there are many open source libraries you can build upon. If you want a simple plug-and-play solution, here are a couple of options:
Name
Type
Registration
SatSale
Self-hosted
No KYC
BTCPay Server
Self-hosted
No KYC
Pay With Flash
Widget

BTCPay Server
Powerful, open-source, self-hosted processor for Bitcoin and Lightning. No KYC.
Supports multiple currencies, advanced features, and full privacy. Requires technical setup and maintenance. Funds go directly to your wallet; great for those seeking full control.
Pay With Flash
Easiest for indie hackers. Add a donation widget with minimal code and no KYC. Payments go directly to your wallet for a 1.5% fee.
Setup Steps:
- Sign up at PayWithFlash.com
- Customize your widget in the dashboard
- Embed the code:
- Test to confirm functionality
Benefits:
- Minimal technical skills required
- Supports one-time or recurring donations
- Direct fund transfer, no intermediaries

The Giving Block
Hosted, KYC required. Integrates with fiat and crypto, best for nonprofits or larger organizations.
OpenNode
Hosted, KYC required. Accept Bitcoin payments and donations; supports conversion to fiat, suitable for businesses and nonprofits.
Summary
- Fast, low-code setup: Use Pay With Flash or Geyser Fund.
- Privacy and control: Choose SatSale or BTCPay Server (requires technical skills).
- Managed, compliant solutions: The Giving Block or OpenNode.
Choose based on your technical comfort, privacy needs, and project scale.

2025-06-17 18:01:40Carl Rickertsen completely exits his position in Strategy as insiders sell $864 million worth of stock.
As reported by Protos, Carl Rickertsen, a member of Strategy’s board of directors, has fully liquidated his entire shareholding for over $10 million.
Rickertsen’s decision to completely exit his Strategy position marks a sharp shift from his previous investment stance. In 2022, the executive had shown confidence in the company by investing $700,000 in MSTR shares.
On June 13, 2022, Rickertsen purchased $608,000 worth of MSTR stock at $152 per share. Since then, the stock has rallied 152%. However, by 2023, the director had already sold half of his 4,000-share position.
Rickertsen’s approach to managing his holdings has become increasingly aggressive in recent years. Since joining the board in 2019, he has adopted a strategy of immediately liquidating any stock options received.
One example of this tactic occurred on June 2, when he acquired and sold 26,390 MSTR shares on the same day.
As of June 5 this year, Rickertsen reported zero vested Strategy shares, marking the end of his equity involvement with the company.
Rickertsen’s situation is not an isolated case within Strategy. Data from the Securities and Exchange Commission (SEC) reveals a controversial picture. According to information gathered by secform4.com, over the past five years, total insider sales have exceeded purchases by $864 million. This imbalance in insider transactions could raise questions about executives’ confidence in the company’s future.

2025-06-17 18:01:39The new communication protocol aims to improve the industry with measurable advantages in terms of efficiency and security.
A new study conducted by Hashlabs, in collaboration with the SRI (Stratum V2 Reference Implementation) team and figures like Matt Corallo, Alejandro De La Torre and others reveals how the Stratum V2 protocol can increase miner profitability compared to the current Stratum V1 standard, used for over a decade.
Speaking to Atlas21, Gabriele Vernetti, Stratum V2 maintainer, declared:
“This first case study demonstrates how much Stratum V2 can help miners as well, securing and increasing their profits, in addition to the rest of the network. It’s just a first study aimed at demonstrating how decentralization can be aligned with the profit dynamics typical of the mining sector.
In the future we will also focus on the benefits for mining pool operators, who can benefit from the protocol’s efficiency to lower their operating costs (such as those for bandwidth used by their servers).
The feedback has been very positive: this first study was a joint work with various market players, including miners and mining pool operators. As SRI we want to continue working together with the entire community as done in this case, becoming a reference point for all actors interested in innovating the Bitcoin mining field”.
The research, based on controlled tests with two identical ASIC S19k Pro, with stock firmware, demonstrates that Stratum V2 can increase net profits by up to 7.4%. For an industry that often operates with 10% margins, this could represent a substantial competitive advantage.
The V2 protocol reduces various inefficiencies that plague the current system. The latency in block switching, that is the waiting time created when a miner must change block template after a new block has been mined on the network, goes from 325 milliseconds to just 1.42 milliseconds, a speed 228 times higher. This translates to about 4.9 hours of completely wasted hash power less per year.
Another problem of modern mining concerns “stale shares” – proofs of work that arrive too late to be remunerated, often due to network latency or inefficient communication. However, not all stale shares depend on inefficiency problems. On average, about 2% are rejected for expected reasons, such as when the share doesn’t reach the minimum difficulty required by the pool. This value is considered normal in the sector. The remaining 98%, instead, is caused by avoidable delays. With Stratum V1, miners lose between 0.1% and 0.2% of their computing power this way. Stratum V2 with Job Declaration completely eliminates this waste, provided that the miner and the pool node have the same level of connectivity. This step could translate into a net profit increase of up to 2% by fully adopting Stratum V2 with Job Declaration.
In the Stratum V2 protocol, the Job Declaration Client (JDC) is software that allows miners to receive mining jobs directly from their local Bitcoin node, that is the block templates to work on. The JDC communicates directly with the miner’s local node, receiving updated data for new block construction and immediately sending them to the mining software via Stratum V2. This allows miners to receive jobs in real time from their own node, without having to wait for them from the pool, reducing latency and the risk of working on obsolete jobs. Furthermore, if the pool allows it, miners can build custom templates choosing which transactions to include in the block.
The research also highlights an often overlooked aspect: the loss of transaction fees. With the Stratum V1 protocol, miners lose about 0.75% of potential fees for each block due to the delay in receiving new jobs. Considering that about 52,560 blocks are mined each year, this loss per block adds up to a total of about 74 bitcoins per year, equivalent to over $8 million at current prices.
Beyond economic advantages, Stratum V2 solves a critical vulnerability of the current system: hashrate hijacking. The V1 protocol doesn’t encrypt communications, allowing attackers to intercept and steal up to 2% of computing power without the miner noticing. The new protocol eliminates this risk through end-to-end encryption and authentication.
According to the study, by reducing latency, optimizing share sending and improving security, Stratum V2 enables a potential net profit increase of 7.4%, derived exclusively from technical improvements.

— ODELL (@ODELL) December 14, 2022
Good morning.
It looks like PacWest will fail today. It will be both the fifth largest bank failure in US history and the sixth major bank to fail this year. It will likely get purchased by one of the big four banks in a government orchestrated sale.
March 8th - Silvergate Bank
March 10th - Silicon Valley Bank
March 12th - Signature Bank
March 19th - Credit Suisse
May 1st - First Republic Bank
May 4th - PacWest Bank?PacWest is the first of many small regional banks that will go under this year. Most will get bought by the big four in gov orchestrated sales. This has been the playbook since 2008. Follow the incentives. Massive consolidation across the banking industry. PacWest gonna be a drop in the bucket compared to what comes next.
First, a hastened government led bank consolidation, then a public/private partnership with the remaining large banks to launch a surveilled and controlled digital currency network. We will be told it is more convenient. We will be told it is safer. We will be told it will prevent future bank runs. All of that is marketing bullshit. The goal is greater control of money. The ability to choose how we spend it and how we save it. If you control the money - you control the people that use it.

2025-06-17 18:01:39French lawmakers are proposing Bitcoin mining as a solution to optimize the national electricity system and make use of surplus energy.
A group of French parliamentarians has introduced an amendment that could turn the country into a European hub for Bitcoin mining, strategically leveraging its energy production capacity.
The legislative proposal aims to assess how mining could be integrated into the French energy system — the largest in Europe — to optimize the management of electricity produced by nuclear power plants.
The amendment to the law on “National Programming and Regulatory Simplification in the Energy Sector” calls on the government to conduct a thorough evaluation of the potential of Bitcoin mining. The initiative represents a pragmatic approach to addressing the issue of excess energy, a key topic for France’s nuclear industry.
France’s energy system, powered by nuclear for over 70% of its needs, often generates electricity surpluses that require efficient management. The proponents of the proposal see mining as an ideal solution to absorb this excess, transforming a potential waste into an economic resource.
The operational flexibility of mining farms offers a unique competitive advantage: machines can be quickly turned on and off based on production and consumption peaks, dynamically adapting to the needs of the electrical grid. This feature makes them particularly suitable for installation near power plants, even in the most remote areas of the country.
The parliamentary proposal highlights how mining could contribute to the revitalization of abandoned industrial sites, creating new opportunities for economic development under the supervision of public authorities.
Lawmakers emphasize the various benefits of this strategy: reducing negative pricing in wholesale markets, relieving the workload on nuclear plants by avoiding frequent modulation cycles that accelerate equipment wear, and absorbing surplus energy that would otherwise go to waste.
The French Association for the Development of Digital Assets (ADAN) collaborated in drafting the amendment, contributing technical expertise and industrial insight to the project. The organization emphasized how low-carbon Bitcoin mining could help strengthen the resilience of the national electricity grid.
The parliamentary report notes that mining in France could represent “an activity tailored to the constraints of the electrical system, absorbing surplus energy and reducing environmental impact” by using power that would otherwise be lost.

Why did Elon buy twitter for $44 Billion? What value does he see in it besides the greater influence that undoubtedly comes with controlling one of the largest social platforms in the world? We do not need to speculate - he made his intentions incredibly clear in his first meeting with twitter employees after his takeover - WeChat of the West.
To those that do not appreciate freedom, the value prop is clear - WeChat is incredibly powerful and successful in China.
To those that do appreciate freedom, the concern is clear - WeChat has essentially become required to live in China, has surveillance and censorship integrated at its core, and if you are banned from the app your entire livelihood is at risk. Employment, housing, payments, travel, communication, and more become extremely difficult if WeChat censors determine you have acted out of line.
The blue check is the first step in Elon's plan to bring the chinese social credit score system to the west. Users who verify their identity are rewarded with more reach and better tools than those that do not. Verified users are the main product of Elon's twitter - an extensive database of individuals and complete control of the tools he will slowly get them to rely on - it is easier to monetize cattle than free men.
If you cannot resist the temptation of the blue check in its current form you have already lost - what comes next will be much darker. If you realize the need to resist - freedom tech provides us options.

"Privacy is necessary for an open society in the electronic age. Privacy is not secrecy. A private matter is something one doesn't want the whole world to know, but a secret matter is something one doesn't want anybody to know. Privacy is the power to selectively reveal oneself to the world." - Eric Hughes, A Cypherpunk's Manifesto, 1993
Privacy is essential to freedom. Without privacy, individuals are unable to make choices free from surveillance and control. Lack of privacy leads to loss of autonomy. When individuals are constantly monitored it limits our ability to express ourselves and take risks. Any decisions we make can result in negative repercussions from those who surveil us. Without the freedom to make choices, individuals cannot truly be free.
Freedom is essential to acquiring and preserving wealth. When individuals are not free to make choices, restrictions and limitations prevent us from economic opportunities. If we are somehow able to acquire wealth in such an environment, lack of freedom can result in direct asset seizure by governments or other malicious entities. At scale, when freedom is compromised, it leads to widespread economic stagnation and poverty. Protecting freedom is essential to economic prosperity.
The connection between privacy, freedom, and wealth is critical. Without privacy, individuals lose the freedom to make choices free from surveillance and control. While lack of freedom prevents individuals from pursuing economic opportunities and makes wealth preservation nearly impossible. No Privacy? No Freedom. No Freedom? No Wealth.
Rights are not granted. They are taken and defended. Rights are often misunderstood as permission to do something by those holding power. However, if someone can give you something, they can inherently take it from you at will. People throughout history have necessarily fought for basic rights, including privacy and freedom. These rights were not given by those in power, but rather demanded and won through struggle. Even after these rights are won, they must be continually defended to ensure that they are not taken away. Rights are not granted - they are earned through struggle and defended through sacrifice.

2025-06-17 18:01:38Russian authorities uncover 95 Bitcoin mining machines hidden inside a truck stealing electricity from a village.
Law enforcement in the Republic of Buryatia has uncovered an illegal Bitcoin mining operation concealed inside a KamAZ truck. The clandestine facility was siphoning off electricity meant for the local population.
According to the national news agency TASS, the discovery was made during a routine inspection of power lines in the Pribaikalsky district, where inspectors identified an unauthorized connection to a 10-kilovolt line — enough to power an entire village. The criminal operation showed a high level of organization, with sophisticated equipment hidden inside an apparently innocuous transport vehicle.
Source: Babr Mash
Inside the commercial truck, authorities found a fully operational mining center equipped with 95 machines and a portable transformer station. The technical setup suggested careful planning, designed to maximize bitcoin production while minimizing the risk of detection.
Two individuals suspected of involvement in the illegal activity managed to escape in an SUV before law enforcement arrived.
Impact of illegal mining on the local power grid
Buryatenergo, a regional unit of Rosseti Siberia, stressed how unauthorized connections severely compromise the stability of the local power grid. Consequences include voltage drops, overloads, and potential blackouts that disproportionately affect rural communities, already vulnerable in terms of energy access.
The illegal siphoning of electricity for mining creates a domino effect across the entire electrical infrastructure, causing service disruptions for legitimate users and increasing maintenance costs for grid operators.
Government restrictions on mining
The Russian government has implemented various restrictions on cryptocurrency mining in several regions of the country. In Buryatia, mining is banned from November 15 to March 15 due to seasonal energy shortages. Only companies registered in specific districts such as Severo-Baikalsky and Muisky are allowed to operate outside this period.
Federal restrictions were further tightened in December 2024, when Russia announced a ban on mining during peak energy months in multiple regions, including Dagestan, Chechnya, and parts of eastern Ukraine under Russian control. Since April, a total ban has been in effect in the southern region of Irkutsk.
Despite these restrictions, some Russian companies continue to operate legally in the sector. BitRiver, one of the country’s leading operators, takes advantage of the region’s low-cost energy, having launched its first and largest facility in 2019 in the city of Bratsk.

2025-06-17 18:01:37The Brazilian government has abolished the Bitcoin tax exemption for small investors and introduced a flat 17.5% tax rate on all crypto capital gains.
Brazil has officially ended the tax-free period for small digital asset investors, introducing a flat 17.5% rate on all profits from cryptocurrency sales. The decision was formalized through Provisional Measure 1303, part of the government’s strategy to increase tax revenues from financial markets.
Until now, Brazilian residents selling up to 35,000 Brazilian reais (around $6,300) in cryptocurrencies per month were completely exempt from income tax. Profits exceeding this threshold were subject to progressive taxation, starting at 15% and reaching up to 22.5% for amounts over 30 million reais.
The new flat rate, which took effect on June 12, removes all exemptions and applies uniformly to every investor, regardless of the size of their transactions, according to local outlet Portal do Bitcoin.
While small-scale investors will now face a higher tax burden, high-net-worth individuals might actually benefit. Under the previous system, large transactions were taxed between 17.5% and 22.5%. With the new flat 17.5% rate, many high-profile investors will see their effective tax liability reduced.
Under the new rules, taxes will be calculated quarterly, with investors allowed to offset losses from the previous five quarters. However, starting in 2026, the time frame for claiming losses will be shortened.
Last March, Brazilian lawmakers also proposed a bill allowing employers to partially pay workers in cryptocurrency. According to the draft, crypto payments could not exceed 50% of an employee’s salary.
Full payment in cryptocurrencies would only be allowed for foreign workers or contractors, and only under specific conditions set by the Brazilian Central Bank. The bill prohibits full crypto payment for standard employees.

It is unconstitutional and would create massive legal restrictions on the open source movement and free speech throughout the internet.
The Bill was proposed by: Senator Warner, Senator Thune, Senator Baldwin, Senator Fischer, Senator Manchin, Senator Moran, Senator Bennet, Senator Sullivan, Senator Gillibrand, Senator Collins, Senator Heinrich, and Senator Romney. It has broad support across Senators of both parties.
Corrupt politicians will not protect us. They are part of the problem. We must build, support, and learn how to use censorship resistant tools in order to defend our natural rights.
The RESTRICT Act, introduced by Senators Warner and Thune, aims to block or disrupt transactions and financial holdings involving foreign adversaries that pose risks to national security. Although the primary targets of this legislation are companies like Tik-Tok, the language of the bill could potentially be used to block or disrupt cryptocurrency transactions and, in extreme cases, block Americans’ access to open source tools or protocols like Bitcoin.
The Act creates a redundant regime paralleling OFAC without clear justification, it significantly limits the ability for injured parties to challenge actions raising due process concerns, and unlike OFAC it lacks any carve-out for protected speech. COINCENTER ON THE RESTRICT ACT

2025-06-16 15:03:06People forget Bear Stearns failed March 2008 - months of denial followed before the public realized how bad the situation was under the surface.
Similar happening now but much larger scale. They did not fix fundamental issues after 2008 - everything is more fragile.
The Fed preemptively bailed out every bank with their BTFP program and First Republic Bank still failed. The second largest bank failure in history.
There will be more failures. There will be more bailouts. Depositors will be "protected" by socializing losses across everyone.
Our President and mainstream financial pundits are currently pretending the banking crisis is over while most banks remain insolvent. There are going to be many more bank failures as this ponzi system unravels.
Unlike 2008, we have the ability to opt out of these broken and corrupt institutions by using bitcoin. Bitcoin held in self custody is unique in its lack of counterparty risk - you do not have to trust a bank or other centralized entity to hold it for you. Bitcoin is also incredibly difficult to change by design since it is not controlled by an individual, company, or government - the supply of dollars will inevitably be inflated to bailout these failing banks but bitcoin supply will remain unchanged. I do not need to convince you that bitcoin provides value - these next few years will convince millions.

2025-06-17 18:01:35VanEck analyst Matthew Sigel warns of growing risks for Bitcoin treasury companies as their stock prices approach NAV.
Matthew Sigel, Head of Digital Assets Research at VanEck, has sounded the alarm for companies that have adopted Bitcoin-based treasury strategies.
No public BTC treasury company has traded below its Bitcoin NAV for a sustained period.
But at least one is now approaching parity.
As some of these companies raise capital through large at-the-market (ATM) programs to buy BTC, a risk is emerging: If the stock trades at or near…
— matthew sigel, recovering CFA (@matthew_sigel) June 16, 2025
In a post on X, Sigel highlighted an emerging issue in the sector of companies holding Bitcoin treasuries. Until now, no public company with a Bitcoin treasury has ever traded below its own Net Asset Value (NAV) for extended periods. The NAV represents the net value of a company’s assets (such as bitcoin and cash) minus its liabilities, divided by the number of outstanding shares — essentially indicating the real value of each share based on the company’s holdings. However, at least one of these companies (Semler Scientific) is now dangerously approaching breakeven.
The core of the issue lies in the capital-raising mechanism. Many of these companies rely on large-scale at-the-market (ATM) programs to acquire bitcoin, but when the stock price nears the NAV, this strategy can shift from creating value to destroying it.
The risk for shareholders
Under normal market conditions, companies like Semler Scientific and Strategy trade at a premium to the value of the bitcoin they hold. This means investors are willing to pay more for the company’s stock than the simple value of its bitcoin treasury.
However, when a company’s stock price approaches or falls below its NAV, the situation becomes problematic, according to Sigel. Issuing new shares at these levels not only dilutes the value for existing shareholders but can also become extractive, as management continues to raise capital while benefiting more than shareholders.
Proposed solutions
Sigel suggested several measures for companies pursuing Bitcoin treasury strategies. His recommendations include implementing preventive safeguards while stock premiums still exist. Notably, he proposes announcing a pause in ATM issuances if the stock trades below 0.95 times NAV for ten or more consecutive trading days. Additionally, Sigel advises prioritizing buybacks when bitcoin appreciates but the company’s equity does not reflect that increase.
Lessons from Bitcoin miners’ past
The VanEck analyst pointed out that similar situations have occurred in the Bitcoin mining sector, marked by persistent equity issuances and disproportionate executive compensation. To avoid repeating those mistakes, Sigel suggests that executive pay should be tied to growth in NAV per share, not the size of the Bitcoin position or the total number of outstanding shares.
Sigel concluded:
“Once you are trading at NAV, shareholder dilution is no longer strategic. It is extractive. Boards and shareholders should act with discipline now, while they still have the benefit of optionality.”

Coinbase Announces Bitcoin Rewards Credit Card, Offering up to 4% BTC Back on EverythingCoinbase is launching its first-ever branded credit card in partnership with American Express, set to roll out this fall. Called the Coinbase One Card, it will be available only to U.S. members of Coinbase One, the platform’s monthly subscription service. The card will offer 2% to 4% back in Bitcoin on everyday purchases, along with access to American Express perks.

— Bitcoin Magazine (@BitcoinMagazine) June 12, 2025
This is a first-of-its-kind product for Coinbase, which previously only offered a prepaid debit card with Visa in 2020.
“We see real potential in the combination of Coinbase and crypto with the powerful backing of American Express, and what the card offers is an excellent mix of what customers are looking for right now,” said Will Stredwick, head of American Express global network services, during the Coinbase State of Crypto Summit in New York.
The card is part of a larger push by Coinbase to expand its subscription-based services. Coinbase One costs $29.99/month and includes zero trading fees, higher staking rewards, and customer support perks. The company also announced a cheaper version—Coinbase Basic—for $4.99/month or $49.99/year, which includes fewer features.
Coinbase’s subscription business is growing fast. It brought in $698.1 million in Q1 2025, compared to $1.26 billion in trading revenue. According to William Blair analyst Andrew Jeffrey, this kind of recurring revenue is a big reason why long-term investors are sticking with the stock.
Launched in 2023, Coinbase One now has over a million members. The company has been steadily growing its ecosystem with products like its Base developer platform and a self-custody wallet.
The company has long positioned Bitcoin at the center of its strategy—offering BTC custody services to institutions, supporting Bitcoin ETFs, integrating Bitcoin rewards into its products, and actively advocating for Bitcoin-friendly regulation in Washington. Coinbase also supports Bitcoin development directly through funding grants and engineering support. As the largest publicly traded crypto exchange in the U.S., Coinbase continues to frame Bitcoin not just as an asset, but as the foundation of its long-term vision.

2025-06-17 18:01:33A new study by Kraken reveals how cryptocurrency investors perceive security as the main challenge in self-managing their digital assets.
According to The Block, a recent survey conducted by crypto exchange Kraken found that nearly half of respondents consider themselves the primary risk factor for their own crypto security. The research, which surveyed 789 participants, highlights that 48% of users see their own actions as the greatest threat to their investments in digital assets, surpassing concerns about external theft or fraud.
Kraken’s report underlines how personal responsibility in security management forces users to take full control of their digital funds. However, the study suggests that this autonomy can also become a source of anxiety for many investors.
Nick Percoco, Chief Security Officer at Kraken, commented on the findings, noting that “a lack of confidence in personal crypto security is capping the growth of the industry.” According to Percoco, unlocking the full potential of cryptocurrencies will require users to embrace self-custody and consistently invest in strong security habits.
Technologies to strengthen security
Despite the concerns highlighted in the study, 31% of participants expressed optimism about future technologies that could improve crypto security. Among the most promising solutions identified:
- advanced biometric systems for user authentication;
- multi-factor authentication to secure wallet access;
- AI-based fraud detection systems to prevent attacks.
Data and case studies
Kraken’s research emerges in a context where security threats remain a pressing reality. FBI data shows that in 2024, nearly 150,000 reports of crypto-related internet fraud resulted in $9.3 billion in losses. Older users, particularly those over 60, proved especially vulnerable, accounting for $3 billion in crypto-related financial fraud losses on their own.

2025-06-16 14:02:15Key Takeaways
Michael Goldstein, aka Bitstein, presents a sweeping philosophical and economic case for going “all in” on Bitcoin, arguing that unlike fiat, which distorts capital formation and fuels short-term thinking, Bitcoin fosters low time preference, meaningful saving, and long-term societal flourishing. At the heart of his thesis is “hodling for good”—a triple-layered idea encompassing permanence, purpose, and the pursuit of higher values like truth, beauty, and legacy. Drawing on thinkers like Aristotle, Hoppe, and Josef Pieper, Goldstein redefines leisure as contemplation, a vital practice in aligning capital with one’s deepest ideals. He urges Bitcoiners to think beyond mere wealth accumulation and consider how their sats can fund enduring institutions, art, and architecture that reflect a moral vision of the future.
Best Quotes
“Let BlackRock buy the houses, and you keep the sats.”
“We're not hodling just for the sake of hodling. There is a purpose to it.”
“Fiat money shortens your time horizon… you can never rest.”
“Savings precedes capital accumulation. You can’t build unless you’ve saved.”
“You're increasing the marginal value of everyone else’s Bitcoin.”
“True leisure is contemplation—the pursuit of the highest good.”
“What is Bitcoin for if not to make the conditions for magnificent acts of creation possible?”
“Bitcoin itself will last forever. Your stack might not. What will outlast your coins?”
“Only a whale can be magnificent.”
“The market will sell you all the crack you want. It’s up to you to demand beauty.”
Conclusion
This episode is a call to reimagine Bitcoin as more than a financial revolution—it’s a blueprint for civilizational renewal. Michael Goldstein reframes hodling as an act of moral stewardship, urging Bitcoiners to lower their time preference, build lasting institutions, and pursue truth, beauty, and legacy—not to escape the world, but to rebuild it on sound foundations.

(00:00) Fiat money is by its nature a disturbance. If money is being continually produced, especially at an uncertain rate, these uh policies are really just redistribution of wealth. Most are looking for number to go up post hyper bitcoinization. The rate of growth of bitcoin would be more reflective of the growth of the economy as a whole.
(00:23) Ultimately, capital requires knowledge because it requires knowing there is something that you can add to the structures of production to lengthen it in some way that will take time but allow you to have more in the future than you would today. Let Black Rockck buy the houses and you keep the sats, not the other way around.
(00:41) You wait until later for Larry Frink to try to sell you a [Music] mansion. And we're live just like that. Just like that. 3:30 on a Friday, Memorial Day weekend. It's a good good good way to end the week and start the holiday weekend. Yes, sir. Yes, sir. Thank you for having me here. Thank you for coming. I wore this hat specifically because I think it's I think it's very apppropo uh to the conversation we're going to have which is I hope an extension of the presentation you gave at Bitblock Boom Huddle for good. You were working on
(01:24) that for many weeks leading up to uh the conference and explaining how you were structuring it. I think it's a very important topic to discuss now as the Bitcoin price is hitting new all-time highs and people are trying to understand what am I doing with Bitcoin? Like you have you have the different sort of factions within Bitcoin.
(01:47) Uh get on a Bitcoin standard, get on zero, spend as much Bitcoin as possible. You have the sailors of the world are saying buy Bitcoin, never sell, die with your Bitcoin. And I think you do a really good job in that presentation. And I just think your understanding overall of Bitcoin is incredible to put everything into context. It's not either or.
(02:07) It really depends on what you want to accomplish. Yeah, it's definitely there there is no actual one-sizefits-all um for I mean nearly anything in this world. So um yeah, I mean first of all I mean there was it was the first conference talk I had given in maybe five years. I think the one prior to that uh was um bit block boom 2019 which was my meme talk which uh has uh become infamous and notorious.
(02:43) So uh there was also a lot of like high expectations uh you know rockstar dev uh has has treated that you know uh that that talk with a lot of reference. a lot of people have enjoyed it and he was expecting this one to be, you know, the greatest one ever, which is a little bit of a little bit of a uh a burden to live up to those kinds of standards.
(03:08) Um, but you know, because I don't give a lot of talks. Um, you know, I I I like to uh try to bring ideas that might even be ideas that are common. So, something like hodling, we all talk about it constantly. uh but try to bring it from a little bit of a different angle and try to give um a little bit of uh new light to it.
(03:31) I alsove I've I've always enjoyed kind of coming at things from a third angle. Um whenever there's, you know, there's there's all these little debates that we have in in Bitcoin and sometimes it's nice to try to uh step out of it and look at it a little more uh kind of objectively and find ways of understanding it that incorporate the truths of of all of them.
(03:58) uh you know cuz I think we should always be kind of as much as possible after ultimate truth. Um so with this one um yeah I was kind of finding that that sort of golden mean. So uh um yeah and I actually I think about that a lot is uh you know Aristotle has his his concept of the golden mean. So it's like any any virtue is sort of between two vices um because you can you can always you can always take something too far.
(04:27) So you're you're always trying to find that right balance. Um so someone who is uh courageous you know uh one of the vices uh on one side is being basically reckless. I I can't remember what word he would use. Uh but effectively being reckless and just wanting to put yourself in danger for no other reason than just you know the thrill of it.
(04:50) Um and then on the other side you would just have cowardice which is like you're unwilling to put yourself um at any risk at any time. Um, and courage is right there in the middle where it's understanding when is the right time uh to put your put yourself, you know, in in the face of danger um and take it on. And so um in some sense this this was kind of me uh in in some ways like I'm obviously a partisan of hodling.
(05:20) Um, I've for, you know, a long time now talked about the, um, why huddling is good, why people do it, why we should expect it. Um, but still trying to find that that sort of golden mean of like yes, huddle, but also what are we hodling for? And it's not we're we're not hodddling just merely for the sake of hodddling.
(05:45) There there is a a purpose to it. And we should think about that. And that would also help us think more about um what are the benefits of of spending, when should we spend, why should we spend, what should we spend on um to actually give light to that sort of side of the debate. Um so that was that was what I was kind of trying to trying to get into.
(06:09) Um, as well as also just uh at the same time despite all the talk of hodling, there's always this perennial uh there's always this perennial dislike of hodlers because we're treated as uh as if um we're just free riding the network or we're just greedy or you know any of these things. And I wanted to show how uh huddling does serve a real economic purpose.
(06:36) Um, and it does benefit the individual, but it also does uh it it has actual real social um benefits as well beyond merely the individual. Um, so I wanted to give that sort of defense of hodling as well to look at it from um a a broader position than just merely I'm trying to get rich. Um uh because even the person who uh that is all they want to do um just like you know your your pure number grow up go up moonboy even that behavior has positive ramifications on on the economy.
(07:14) And while we might look at them and have uh judgments about their particular choices for them as an individual, we shouldn't discount that uh their actions are having positive positive effects for the rest of the economy. Yeah. So, let's dive into that just not even in the context of Bitcoin because I think you did a great job of this in the presentation.
(07:36) just you've done a good job of this consistently throughout the years that I've known you. Just from like a first principles Austrian economics perspective, what is the idea around capital accumulation, low time preference and deployment of that capital like what what like getting getting into like the nitty-gritty and then applying it to Bitcoin? Yeah, it's it's a big question and um in many ways I mean I I even I barely scratched the surface.
(08:05) uh I I can't claim to have read uh all the volumes of Bombber works, you know, capital and interest and and stuff like that. Um but I think there's some some sort of basic concepts that we can look at that we can uh draw a lot out. Um the first uh I guess let's write that. So repeat so like capital time preference. Yeah. Well, I guess getting more broad like why sav -

2025-06-17 18:01:30Bluebird Mining Ventures Ltd., a UK-listed gold exploration company, has made headlines after announcing it will convert future revenues into bitcoin. This is the first time a UK mining company has committed to having a bitcoin treasury.
Bluebird Mining on X
The news sent Bluebird’s stock flying, rising 63% to £0.6 in 48 hours.
Bluebird which has gold projects in South Korea and the Philippines says this is part of a broader plan to modernize how it manages its finances.
“By adopting a ‘gold plus a digital gold’ strategy, it offers the Company an opportunity to turn the page and look to the future and seek to attract a new type of shareholder,” said Aidan Bishop, Interim CEO and Executive Director.
The company’s management believes bitcoin’s rise as a financial asset reflects growing dissatisfaction with traditional stores of value like gold.
Gold has been a reliable hedge against inflation for centuries, but bitcoin is now being seen as a digital alternative – thanks to its limited supply and independence from central bank policies.
Related: Gold at Historic Low Against Bitcoin | A Paradigm Shift?
“Gold’s position as a store of value has been under threat due to the rising global adoption of bitcoin, which some commentators have described as ‘digital gold’,” Bluebird said in a statement.
The plan is simple. Revenue from Bluebird’s gold mining projects will be used to buy bitcoin. The company says this will allow it to preserve capital and have growth potential through exposure to the digital asset market.
The digital asset will be held on the company’s balance sheet as a long-term reserve asset, just like some companies hold gold or cash. Bluebird sees this as proactive, especially in today’s volatile world of inflation, high debt, and global geopolitical tensions. Bishop said:
“I am convinced that we are witnessing a tectonic shift in global markets and that Bitcoin will reshape the landscape of financial markets on every level.”
Bluebird Mining Ventures is a small but big-thinking company.
With 7 employees and operations across Asia, it’s focused on reopening high-grade gold mines that have been closed. Its main projects are the Gubong and Kochang mines in South Korea and the Batangas Gold Project in the Philippines.
In May 2025, the company renewed its mining permit in the Philippines and is finalizing a deal with its local partner to have a “free carry” — meaning it will hold a share of the future profits without putting in any more money.
At the same time, Bluebird is preparing legal action in South Korea to protect its existing assets there, so while it loves Bitcoin, it hasn’t forgotten its mining roots.
To lead this transformation, Bluebird is currently looking for a new CEO with Bitcoin experience. The company says the right leadership will be key to navigating this hybrid financial model that combines traditional resource extraction with modern financials.

2025-06-17 18:01:09In a quiet corner of the world, bitcoin mining operations in Africa are turning electricity into digital currency and in the process, redefining how value is created.
At its core, bitcoin mining involves validating transaction information before adding new blocks to the Bitcoin blockchain by competing to solve a cryptographic puzzle that meets a specific criterion.
Globally, mining plays a key role in keeping the blockchain decentralized and secure. The system depends on miners to verify and record transactions, mainly to prevent a problem called double spending, the digital version of using the same money twice.
To understand this better, imagine Charles sends $5 to Amanda. With physical cash, Amanda can trust the note is real and hasn’t been used elsewhere. But with digital currency, copying data is easy, so how can she be sure that the same $5 wasn’t sent to someone else too? That’s the exact problem Bitcoin mining helps solve.
In recent years, Africa has started to draw attention in this space, positioning itself as a key hub in global bitcoin mining. While there may be less than 2 million bitcoin left to be mined from the total 21 million supply, the rise of mining operations in Africa has sparked excitement, creating new jobs and drawing in foreign capital.
Although some countries still grapple with power shortages and the energy demands of mining, many citizens view bitcoin as a more stable store of value and a safeguard against the volatility of their local currencies.
At the same time, Africa’s wealth of hydro, solar, wind, and geothermal resources makes the continent one of the most promising regions for cost-effective and sustainable mining.
What Makes a Large-Scale Bitcoin Mining Operation in Africa?
It all starts with difficulty. Bitcoin mining isn’t just about solving a puzzle, it’s about solving one that keeps getting harder. Mining difficulty refers to how much computational work is needed to generate a number lower than the target hash.
This difficulty automatically adjusts every 2,016 blocks (about every two weeks), depending on how quickly miners solved the previous batch. If mining is fast and efficient, the network increases the difficulty; if miners drop off and block times slow, it reduces it, all to maintain a consistent block production time of roughly 10 minutes.
The significance of mining difficulty lies in the increased demands it places on mining operations. As difficulty rises, miners require more powerful hardware, cost-effective energy sources, advanced infrastructure, and substantial financial investment. These requirements distinguish large-scale mining operations from smaller, casual miners.
In short, it’s the difficulty of mining that births the need for large facilities, massive energy inputs, industrial-grade hardware, and significant financial investment, the very traits that define a “large” bitcoin mining operation.
This leads us to the 4 key factors that define large Bitcoin mining operations in Africa, each one a direct response to the growing demands of the network:
1. Facility size and infrastructure:
The physical size of a mining facility is a direct reflection of its capacity to house mining equipment and support systems. Larger operations typically have thousands of mining rigs installed, supported by extensive infrastructure such as advanced cooling systems and stable power supplies.
These are critical to ensure that the equipment runs continuously and efficiently, given the intense heat and electricity demands of mining.
While it is possible to mine Bitcoin using desktop computers or gaming rigs by joining mining pools, these setups are limited in profitability. Mining pools distribute rewards based on the computational power contributed, meaning small or less efficient machines earn only modest returns.
To compete effectively, mining operations invest in specialized hardware known as Application-Specific Integrated Circuit (ASIC) miners. These machines are far more powerful and energy-efficient than regular computers but require significant capital investment, with prices ranging from $4,000 to $12,000 per rig depending on their performance.
Large-scale operations typically deploy hundreds or thousands of these ASIC miners, which necessitates the large facilities and sophisticated infrastructure mentioned earlier. In this way, the size of the facility and the sophistication of the mining equipment are tightly linked, together defining the overall scale and capability of a bitcoin mining operation.
2. Hashrate contribution:
Hashrate refers to the computational power used to mine and process transactions on the Bitcoin network. A higher hashrate indicates a more significant contribution to the network’s security and transaction processing.
Large mining operations often possess substantial hashrate, measured in exa hashes per second (EH/s). For instance, as of July 2024, the Bitcoin network’s hashrate was approximately 733.41 EH/s.
3. Energy consumption and power source:
Bitcoin mining is energy-intensive. The total energy consumption of the Bitcoin network has been estimated at 175.87 terawatt-hours annually, comparable to the power consumption of Poland. Large mining operations often seek locations with access to cheap and reliable energy sources, such as hydroelectric, solar, or wind power, to reduce operational costs and environmental impact.
4. Financial banking and investor interest:
Significant financial investment is required to establish and maintain large-scale mining operations. This includes the cost of mining hardware, facility construction, energy procurement, and operational expenses. Companies with substantial financial backing can invest in cutting-edge technology and infrastructure, enhancing their mining capabilities.
Overview of Bitcoin Mining in Africa
Africa is beginning to carve out its share of the global Bitcoin mining market, which was valued at $2.45 billion in 2024 and is projected to reach $8.24 billion by 2034.
As Bitcoin’s value continues to rise, countries across the continent are positioning themselves to benefit, many by tapping into abundant renewable energy sources and taking advantage of regulatory ambiguity or excess energy production.
Ethiopia currently leads the continent in Bitcoin mining activity, with around 2.5% of the global hashrate reportedly coming from operations powered entirely by renewable energy.
This energy mismatch has attracted major miners from China and other regions, who see an opportunity to monetize surplus electricity. Ethiopia’s success showcases how renewable energy and mining can coexist sustainably while contributing meaningfully to state revenue.
Kenya follows closely behind. As the top geothermal energy producer in Africa, with an installed capacity of 863 MW, the country is using its energy advantage to support sustainable mining.
Nigeria is emerging as a serious contender. While not yet dominant, its large population, increasing tech engagement, and growing interest in using flared gas for mining signal potential for expansion. Nigeria’s complex but evolving regulatory landscape also leaves room for further mining developments as the government explores clearer crypto frameworks.
Malawi represents a more localized model of Bitcoin mining. By converting rainfall-powered microgrids into revenue-generating infrastructure, Malawi shows how small-scale mining can play a powerful role in community development and rural electrification.
In Libya, Bitcoin mining is technically illegal, but that hasn’t stopped it. Despite the ban, underground mining continues to thrive thanks to heavily subsidized electricity. In 2021, Libyan miners accounted for an estimated 0.6% of the global Bitcoin production, the highest in both the Arab world and Africa at the time. Today, mining reportedly consumes around 2% of the country’s electricity, even as it operates in the shadows.
Angola rounds out the list with limited public data but notable potential. The country struggles with energy inefficiencies, losing nearly 40% of its hydroelectric power during transmission. Some reports suggest Bitcoin miners are beginning to capitalize on this otherwise stranded energy, though large-scale operations are yet to surface.
What unites these countries is a shared set of conditions: untapped or mismanaged energy resources, an openness or gray area in regulation, and the growing understanding that Bitcoin mining can serve as a financial incentive to build and stabilize decentralized energy systems.
Whether through massive hydroelectric projects or rural microgrids, Bitcoin mining is emerging as both an energy monetization strategy and a bridge to infrastructure development across Africa.

👉🏽 The United States Treasury just bought back $10 Billion of its own debt, the largest Treasury buyback in history.
Buying back your own debt with printed money. That's what happens just before fiat money goes to die (eventually). Eventually, nobody wants that worthless debt anymore, eventually!
Context by EndGame Macro:
💰 $10 Billion Buyback: The Treasury’s Silent Signal
On June 3, 2025, the U.S. Treasury quietly executed the largest debt buyback in American history, repurchasing $10 billion in short- and medium-term bonds. At first glance, it looked routine. But under the surface, this was a stealth intervention aimed at calming a system under increasing strain. This wasn’t just liquidity smoothing. It was strategic triage.
🧾 What Happened
Buyback Size: $10B (a record)
Debt Offered: $22.87B — more than double what was accepted
Target Maturities: July 2025 to May 2027
Issues Accepted: 22 of 40 eligible
Settlement: June 4, 2025
That huge offer volume isn’t just noise—it’s a warning sign that institutional players are under pressure.
🚨 What the Buyback Really Signaled
- A Quiet Circuit Breaker The buyback focused on maturities clustered around a $9 trillion rollover wall over the next 12 months. Without announcing it, the Treasury effectively tripped a circuit breaker to reduce near-term funding stress.
- QE Without the Label This wasn’t the Fed. No balance sheet expansion. But by retiring debt ahead of maturity and shrinking market float, the effect mirrored QE—without the political baggage.
- Institutions Are Feeling the Squeeze A staggering $22.87 billion in offers points to constraints at banks, funds, or foreign reserve desks. The Treasury didn’t save everyone—just enough to relieve pressure quietly.
🎯 Strategic Motivation
This wasn’t about boosting confidence. It was about managing two threats: Maturity Wall Risk: Avoiding auction failures as short-term debt piles up in 2025–2026. Yield Curve Stability: Preventing disorderly spikes by quietly absorbing supply. This move avoided triggering headlines—while containing the fire under the hood.
🧠 Echoes from History
This buyback fits into a lineage of quiet but powerful interventions: Operation Twist (1961) – Rebalancing maturity without QE branding. BoE Gilt Crisis (2022) – Targeted long-end intervention to save pensions. Belgium’s Shadow QE (2014) – U.S. debt absorbed off-balance-sheet during geopolitical tension. Each move relied on subtlety and intent—not optics.
🧩 What the Market Heard
Primary Dealers: Help exists—but it’s selective and discretionary.
Foreign Holders: Exit in order—or risk exclusion.
Money Markets: Relief, not resolution.
❗ Where the Logic Cracks
If this was routine: Why buy back below par? Why accept only 44% of the offered debt? Why deploy this now and not earlier? Each of these points to deeper stress than officials are openly admitting.
🔒 High-Conviction Takeaway
This buyback was a preemptive stabilization maneuver, not a stimulus. With over $9 trillion in short-term debt set to roll, foreign participation weakening, and institutional selling pressure rising, the Treasury acted before fractures became visible. The line wasn’t drawn to show strength. It was drawn behind the market—to stop a collapse.
🕵️♂️ Known Unknowns
Who were the biggest sellers—and what’s pressuring them? Was this coordinated with the Fed or global reserve desks? Is this a one-off event—or the start of a multi-phase liquidity campaign? The silence is strategic—but the signal is loud.
👉🏽Joe Consorti: 'Congress refuses to cut spending. So we must "grow our way out" of the deficit. That would take 39 years of 5% nominal GDP growth, or 22 years at 10%. In other words, 2-4 decades of explosive growth just to break even. We can't "grow our way out". We'll print our way out.'
👉🏽ZeroHedge: And just like that, the "climate crisis" is gone https://i.ibb.co/GQ76Z79P/Gsr3uus-XEAAjuv6.png
Don't get me wrong and with all respect to my environmentalist friends, but the “Crisis” never existed. A big part of the push has been marketing dollars/euros and media spin, let's face it.
Why do I think that? How do you think we will grow out of the Global Debt problem? One word: PRODUCTIVITY.
How can we manage that? They (Governments/Central Banks) need AI data farms. What do data farms need?
Electricity, water, energy.
Because Big Tech and AI need energy -- wherever they can find it -- climate change as a cause is finished. It was all virtue signaling. And remember the climate didn’t cool, it just stopped polling well. The scariest part of the “climate crisis” becoming out-of-vogue with the left is that it'll likely be replaced by something equally absurd and artificially manufactured.
On the 6th of June
👉🏽 'The US economy adds 139,000 jobs in May, above expectations of 126,000. The unemployment rate was 4.2%, in line with expectations of 4.2%. The April jobs number was revised down from 177,000 to 147,000. The headline numbers continue to exceed expectations.' - TKL
Surprise, surprise…
March jobs revised: 185K 120K (-65k)
April jobs revised: 177K 147K (-30k)
13 of the L16 have been revised lower.
Just to make it even worse, this is something I have shared multiple times in 2024. The number of year-over-year private job gains in 2024 was likely overstated by a MASSIVE 907,000 jobs, according to BLS data released Wednesday. This comes as the Quarterly Census of Employment and Wages (QCEW) data covering 97% of employers showed a private payroll growth rate of 0.6% for December 2024. This is 50% lower than the 1.2% growth rate initially reported in the monthly non-farm payroll (NFP) reports. To put this differently, there was a 907,000 gap between NFP data and QCEW data in 2024. This means jobs were likely overstated by an average of 75,583 PER MONTH in 2024.
👉🏽Opinion: Milei reduced government spending by 30% and achieved a surplus in only 1 month. His popularity didn't fall, it rose. Don't tell me fiscal discipline isn't popular with the general public. It's just unpopular to the powerful special interests that control DC or Brussels.
👉🏽'In the current fiscal year, the U.S. government already spent $4,159 billion. This is for the first 7 months and the fiscal year ends in September. The latest available data is as of April. The already accrued deficit amounts to over $1 trillion: $1,049 billion.
You can see in the chart how net interest expense has become the #2 largest spending category at $579 billion (for 7 months) after social security ($907 billion) and even exceeded national defense ($536 billion), health ($555 billion), and Medicare ($550 billion). The deficit is 34% of total receipts! (1049/3110) In other words: the U.S. government spent 34% more than it took in.
The last full fiscal year ended in September 2024. In that fiscal year, we spent $1.13 trillion on interest expenses. After only the first 7 months of fiscal year 2025 ending in September, they are already at $776 billion. This means we'll likely touch $1.3 trillion this fiscal year!' - AJ https://i.ibb.co/RTLTZPn1/Gsxv-Tso-Xc-AAZs-Zo.jpg

👉🏽 The EU Commission paid climate "NGOs" for questionable lobbying with money from German taxpayers and wanted to keep it secret. https://i.ibb.co/zH6J41Zq/Gsz-Lu-F9-Xg-AAZttn.jpg Now read the above statement again and after that read the following bit:
👉🏽EU TRIES TO LECTURE EL SALVADOR - BUKELE BODYSLAMS BACK Source: https://www.eeas.europa.eu/eeas/el-salvador-statement-spokesperson-foreign-agents-law-and-recent-developments_en
The Diplomatic Service of the European: "El Salvador: The EU regrets the adoption of the Foreign Agents Law, which risks restricting civil society and runs counter to international obligations. Recent arrests of human rights defenders raise further concerns."
The EU’s sanctimonious finger-wagging at El Salvador reeks of hypocrisy. Brussels lectures sovereign nations on “civil society” while funneling billions into globalist NGOs that undermine national sovereignty. The institution that attacks liberty, freedom, democracy, and free speech in the name of a neosocialist woke ideology wants to lecture other countries on how they defend against their constant meddling and aggression. They are a bunch of unelected bureaucrats, accountable to no one, representing no one. Classic!
Supporting this further, let’s have a look how the EU is increasingly positioning itself as a technocratic regulator of personal freedom:
'The EU – the one that:
•wants to monitor every Bitcoin transaction through MiCA & DAC-8 •would love to ban non-custodial wallets
•is planning a chat control law that would make even China blush
•is considering a wealth register to digitally track every cent of your retirement savings
•restricts cash withdrawals in some member states •is testing CBDCs with expiration dates and spending limits
•and is preparing the digital euro as a full-blown control tool
…this EU is now complaining about human rights violations in El Salvador – a country whose government enjoys one of the highest approval ratings in the world. Over 85% support for President Bukele. Show me a single Western leader who even comes close to that.' - Bitcoin Hotel
Great reply by El Salvador's President Nayib Bukele: 'EU: El Salvador regrets that a bloc which is aging, overregulated, energy-dependent, tech-lagging, and led by unelected bureaucrats still insists on lecturing the rest of the world.'

👉🏽'US existing home sales dropped -3.1% year-over-year to an annualized 4.0 million in April, the lowest for any April since 2009. Month-over-month, home sales fell 0.5%, well below expectations of a +2.0% increase. The decline was driven by the West and Northeast regions. Sales in the South were flat, while in the Midwest improved slightly. Meanwhile, existing home inventory rose +21%, to 1.45 million, the most for any April since 2020, per ZeroHedge. Despite that, the median sales price increased +1.8% year-over-year to $414,000, a record for April. Homebuyer demand is weak and prices are still rising.' -TKL
On the 9th of June:
👉🏽Jeroen Blokland: '- China bought more gold in May. -China has been buying even more gold through ‘unofficial’ channels. - China's gold reserves today are low compared to those of the US and European countries -China is determined to move away from US dollar hegemony - China’s ambition to move away from the US dollar will only have strengthened because of the Trump tariff war - China has to acknowledge that few countries, companies, and households want to hold the Yuan So what will China be doing for years to come?'
No surprise central banks are avoiding sovereign debt and adding gold.
👉🏽TKL: Gold is on fire: Gold's share of global reserves reached 23% in Q2 2025, the highest level in 30 years. Over the last 6 years, the percentage has DOUBLED. At the same time, the US Dollar's share of international reserves has declined 10 percentage points, to 44%, the lowest since 1993. By comparison, the Euro's share has decreased 2 percentage points, to 16%, the lowest in 22 years. Gold is quickly replacing fiat currencies as a reserve currency.
🎁If you have made it this far, I would like to give you a little gift:
Lysander: "Lyn Alden gave one of the clearest breakdowns of why the U.S. is on an unstoppable fiscal path—and why Bitcoin matters more than ever because of it.
Lyn Alden walks through the numbers behind the federal deficit, interest expenses, Social Security, and the structural changes that happened post-2008. The short version? We’re in a new era. One where the government can’t slow down even if it wants to.
Her phrase: “Nothing stops this train.” Not because of ideology, but because of math—and human nature.
This isn’t hyperinflation doom-talk. It’s a sober look at what happens when a system built on ever-growing debt reaches its limits—and why Bitcoin, with its fixed supply and transparent rules, is the opposite of that system.

H100 Group Receives 144.8 BTC in Convertible Loan DealH100 Group, Swedish health-tech firm, has received 144.8 BTC as part of a settlement tied to its convertible loan agreement, according to a company press release issued Monday. With this latest transaction, the Stockholm-based firm now holds a total of 169.2 BTC on its balance sheet.
H100 Group Receives 144.8 BTC as Partial Settlement Under Convertible Loan Framework. Now holds 169.2 BTC. pic.twitter.com/MAW044iXkG
— H100 (@H100Group) June 16, 2025
The 144.8 BTC was transferred as a part of the first four segments of H100’s loan agreement, which has been well received by investors thus far. H100 said in the release, “H100 Group AB (‘H100 Group’ or the ‘Company’) has today received 144.8 BTC as part of the proceeds from Tranches 1 through 4 under its previously announced convertible loan agreements.”
This follows recent reporting that Blockstream CEO Adam Back committed to lead a 750 million kronor (~$79 million) funding initiative for H100, anchored by a 150 million-krona injection in Tranche 6. The loan, structured for speed and cost-efficiency, was priced at 6.38 kronor per share—a 33% premium to market—showing investor confidence.
The loan structure includes settlement flexibility—either in cash or Bitcoin—which allows counterparties to opt for BTC delivery, reducing fiat friction and lining up with the firm’s long-term treasury outlook.
“Unexpectedly, given the strong reception, Tranches 1-4 became in-the-money rapidly,” Back told CoinDesk. “I was expecting [H100] would convert them over time as they reached in-the-money status.”
This funding approach allows H100 to bypass traditional rights issues while onboarding capital in a flexible manner. Tranches 7 and 8 are on deck, with room for size increases depending on market appetite.
This also reflects H100’s evolving financial strategy. While the company’s core operations remain focused on AI-driven health and longevity services, its growing Bitcoin position is reshaping how capital is raised, stored, and deployed. As of now, the company’s BTC holdings stand at 169.2 BTC—up from just 24.41 BTC prior to this latest tranche execution.
H100’s stock jumped 22% on Monday in response to the developments.
As the firm continues negotiations for future tranches and explores adoption of BTC as a financial backbone, it positions itself uniquely at the intersection of health tech and decentralized finance.

Flash Releases Free Bitcoin Invoicing Tool with No Fees, KYC, or CustodyFlash, a Bitcoin payment platform, just announced it has launched Flash Invoicing, a completely free, non-custodial, and KYC-free Bitcoin invoicing tool. Designed for freelancers, the platform allows users to send professional invoices without platform fees, identity checks, or third party custody.
According to Deel, a crypto payments company for freelancers, Bitcoin is the most used cryptocurrency in the world for payments. Despite this growth, many freelancers continue to use basic methods such as pasting Bitcoin addresses into PDFs or emails. Some rely on custodial platforms that deduct fees or require identity verification, which can affect both earnings and data privacy.
“We’ve seen too many people paste BTC addresses into documents and call it invoicing,” said the CEO of Flash Pierre Corbin. “It’s messy. It’s risky. And it’s time for something better.”
Flash Invoicing Features:
- 0% platform fees: no subscriptions or commission
- Non-custodial: Bitcoin goes straight to the user’s wallet
- No KYC: users maintain full privacy
- Professional output: branded PDFs and secure payment links
- Integrated dashboard: manage payments, clients, and revenue
- Works with Flash ecosystem: including Stores, Donations, Paywalls, and POS
Many Bitcoin invoicing tools charge a percentage per transaction or require a subscription. As a result, freelancers often lose part of their income simply to issue an invoice and receive payment. Flash is aiming to solve this issue.
“Freelancers work hard enough. The last thing they need is a platform skimming off their earnings,” said Corbin. “That’s why we dropped our fee from 1.5% to 0% — and launched the first invoicing tool that’s truly free, without compromising on privacy or control.”
Flash Invoicing allows users to accept Bitcoin payments without relinquishing control, privacy, or revenue. It is integrated with the broader Flash suite, enabling users to manage invoicing alongside features such as setting up stores, receiving donations, or gating premium content.
“As a freelancer myself, I love using the Flash invoicing feature,” stated a freelancer & Flash user. ”It keeps all my clients in one place, allows me to easily edit invoices and track payments. Much more professional than sending a lightning address in the footer of a PDF invoice.”

Thailand Approves Five Year Bitcoin And Crypto Tax BreakThailand has approved a five year tax exemption on capital gains from cryptocurrency trading made through licensed digital asset platforms. The exemption will be in effect from January 1, 2025, through December 31, 2029.

— Bitcoin Magazine (@BitcoinMagazine) June 17, 2025
Deputy Finance Minister Julapun Amornvivat announced the measure, calling it a move to increase investment, stimulate economic activity, and drive long term growth.
Amornvivat stated, “The Cabinet approved a five-year crypto tax exemption to promote Thailand as a global digital asset hub.”
According to the Ministry of Finance, the policy is designed to strengthen Thailand’s competitiveness in the global digital economy. It targets transparent growth, and aims to increase capital inflow into the Thai market. Officials expect over 1 billion baht in indirect tax revenue to result from the increased economic activity during the exemption period.
Amornvivat went on to say, “The capital gain tax exemption will be for the sale of digital assets made through operators regulated by the Securities and Exchange Commission.”
The tax break applies only to platforms licensed by the Thai SEC. This includes exchanges that meet strict regulatory standards under the government’s digital finance framework. Exchanges without Thai licenses will not benefit from the exemption and continue to face restrictions.
Officials say the new exemption aligns with international standards from the OECD and FATF. The government is also exploring a possible value-added tax (VAT) on digital assets to support fiscal stability.
Furthermore, this isn’t Thailand’s first step toward embracing Bitcoin or crypto.
Thailand approved its first spot Bitcoin ETF in 2024, allowing asset manager ONEAM to launch a fund for institutional investors. The ETF offers regulated exposure to Bitcoin through global funds and reflects growing demand for institutional access to the asset.
Thailand is taking a two sided approach. They support innovation through licensed platforms, while cracking down on unregulated players. With clearer rules and tax breaks, the country is positioning itself as a leader for Bitcoin and crypto growth in Southeast Asia.

Fold Holdings Secures $250 Million Equity Deal to Expand Bitcoin TreasuryToday, Fold Holdings, Inc. (NASDAQ: FLD), the first publicly traded bitcoin financial services company, has announced a $250 million equity purchase agreement to significantly increase its bitcoin holdings.
JUST IN:
Publicly traded Fold secures $250 million equity facility to buy more #Bitcoin pic.twitter.com/M7E3fzwAsT
— Bitcoin Magazine (@BitcoinMagazine) June 17, 2025
Fold Holdings has the option, but not the obligation, to issue and sell up to $250 million in new common stock. The ability to access the funds is subject to certain conditions, including the requirement that a registration statement covering the resale of the stock be filed with and approved by the Securities and Exchange Commission (SEC).
“The Company is not required to use the Facility and controls the timing and amount of any drawdown on the Facility, subject to certain restrictions under the Facility,” said the press release. “The Company expects to use the net proceeds from the Facility, if any, primarily to acquire additional bitcoin for Fold’s corporate treasury.”
The shares offered under the facility will be issued through a private placement, relying on exemptions from the registration requirements of the Securities Act of 1933 and Regulation D. Fold noted that it “plans to file with the SEC a registration statement relating to the resale of the Common Stock issuable under the Facility.”
“The offers and sales of the Common Stock issuable under the Facility will be made in a private placement in reliance on an exemption from the registration requirements of the Securities Act of 1933,” according to the press release. “The Company cannot draw on the Facility, and the Common Stock may not be sold nor may offers to buy be accepted, prior to the time that the registration statement covering the resale of the Common Stock is declared effective by the SEC.”
On May 19, Fold also announced the launch of its Bitcoin gift card, marking its entry into the $300 billion U.S. retail gift card market. This new product allows consumers to purchase and gift bitcoin through familiar retail channels, with plans to expand to major retailers nationwide throughout the year.
“This gift card gives us distribution directly to millions of Americans who may not be buying Bitcoin because they haven’t downloaded a new app, don’t have a brokerage account, or haven’t seen the ETF,” said the Chairman and CEO of Fold Will Reeves.
“I think there’s a real chance by the end of 2025 that Bitcoin becomes the most popular gift in America because of this card,” stated Reeves.

2025-06-16 10:01:55What is KYC/AML?
- The acronym stands for Know Your Customer / Anti Money Laundering.
- In practice it stands for the surveillance measures companies are often compelled to take against their customers by financial regulators.
- Methods differ but often include: Passport Scans, Driver License Uploads, Social Security Numbers, Home Address, Phone Number, Face Scans.
- Bitcoin companies will also store all withdrawal and deposit addresses which can then be used to track bitcoin transactions on the bitcoin block chain.
- This data is then stored and shared. Regulations often require companies to hold this information for a set number of years but in practice users should assume this data will be held indefinitely. Data is often stored insecurely, which results in frequent hacks and leaks.
- KYC/AML data collection puts all honest users at risk of theft, extortion, and persecution while being ineffective at stopping crime. Criminals often use counterfeit, bought, or stolen credentials to get around the requirements. Criminals can buy "verified" accounts for as little as $200. Furthermore, billions of people are excluded from financial services as a result of KYC/AML requirements.
During the early days of bitcoin most services did not require this sensitive user data, but as adoption increased so did the surveillance measures. At this point, most large bitcoin companies are collecting and storing massive lists of bitcoiners, our sensitive personal information, and our transaction history.
Lists of Bitcoiners
KYC/AML policies are a direct attack on bitcoiners. Lists of bitcoiners and our transaction history will inevitably be used against us.
Once you are on a list with your bitcoin transaction history that record will always exist. Generally speaking, tracking bitcoin is based on probability analysis of ownership change. Surveillance firms use various heuristics to determine if you are sending bitcoin to yourself or if ownership is actually changing hands. You can obtain better privacy going forward by using collaborative transactions such as coinjoin to break this probability analysis.
Fortunately, you can buy bitcoin without providing intimate personal information. Tools such as peach, hodlhodl, robosats, azteco and bisq help; mining is also a solid option: anyone can plug a miner into power and internet and earn bitcoin by mining privately.
You can also earn bitcoin by providing goods and/or services that can be purchased with bitcoin. Long term, circular economies will mitigate this threat: most people will not buy bitcoin - they will earn bitcoin - most people will not sell bitcoin - they will spend bitcoin.
There is no such thing as KYC or No KYC bitcoin, there are bitcoiners on lists and those that are not on lists.

Ukraine Introduces Bill to Allow Bitcoin in National ReservesUkraine has introduced a bill that would give its central bank the legal right to hold Bitcoin and other assets as part of its national reserves. The draft law, submitted to the Verkhovna Rada on June 10, 2025, proposes updates to existing legislation to include “virtual assets” in the foreign exchange and gold reserves of the National Bank of Ukraine (NBU).
NEW: Ukraine introduces bill for Bitcoin Reserve in Parliament
pic.twitter.com/bYIiCNF13D
— Bitcoin Magazine (@BitcoinMagazine) June 17, 2025
This doesn’t mean Ukraine is officially adding Bitcoin to its balance sheet just yet, but it would give the central bank the green light to do so in the future.
One of the bill’s co-sponsors, Member of Parliament Yaroslav Zhelezniak, emphasized that the legislation is about granting permission, not making it a requirement. “Whether and to what extent they actually do so,” he said, “is up to the institution itself.”
Zhelezniak recently discussed with Binance’s regional head Kyrylo Khomiakov, that he believes Bitcoin could help Ukraine strengthen its economic position and contribute to long term digital innovation.
The timing of the bill is vital as Ukraine has been under enormous financial pressure since Russia’s invasion in 2022. Inflation remains high, the hryvnia has lost significant value, and the country is heavily reliant on international aid and loans. The NBU has managed to hold roughly $44.5 billion in reserves, mostly in U.S. dollars and government securities, but its room to maneuver is limited.
Back in 2022, the Ukrainian government was actively raising donations for the war effort through Bitcoin. They had an official wallet set up for donations, and their politicians were publicly tweeting out the addresses asking for support. On the first day alone, Ukraine’s official Bitcoin wallet raised over $3.5 million. By leaning into Bitcoin during their time of crisis, the government showed their belief and commitment in it, and this new bill shows that that commitment has not faded.
NEW
Ukraine government #Bitcoin wallet raises OVER $3.5 MILLION in 1st day of donations
— Bitcoin Magazine (@BitcoinMagazine) February 27, 2022
If this bill is adopted, it could position Ukraine as one of the first countries to give its central bank the legal ability to hold Bitcoin as a strategic reserve asset.

2025-06-17 17:49:18Ele é uma espécie de ponte do Tor que permite que os usuários se conectem à rede Tor por meio de um sistema distribuído de voluntários.
A história do Snowflake começou em 2019, quando o Tor Project percebeu que muitas pessoas em locais com restrições de acesso à Internet estavam recorrendo a soluções de VPN e proxies para contornar a censura. No entanto, muitas dessas soluções eram bloqueadas pelas autoridades governamentais, o que criou a necessidade de encontrar novas maneiras de contornar a censura. Foi aí que surgiu a ideia do Snowflake, que foi lançado como uma solução para ajudar a aumentar a capacidade do Tor de contornar a censura da Internet em todo o mundo.
O Snowflake funciona por meio de um sistema distribuído de voluntários que oferecem seus proxies para ajudar a contornar a censura. Quando um usuário se conecta ao Snowflake, seu tráfego é roteado por meio de um conjunto de proxies voluntários que se oferecem para ajudar a contornar a censura. Esses proxies são distribuídos em todo o mundo, o que ajuda a garantir que haja sempre uma opção disponível para os usuários que desejam acessar a Internet livremente.
O Snowflake resolve o problema de acesso à Internet em locais onde o acesso ao Tor é bloqueado. Ele permite que os usuários contornem a censura e a vigilância da Internet, acessando sites e aplicativos que seriam bloqueados em suas regiões. Com o Snowflake, os usuários podem navegar na Internet com mais privacidade e segurança, evitando serem detectados pelos censores da Internet.
"A privacidade é necessária para uma sociedade aberta na era eletrônica. Privacidade não é sigilo. Uma sociedade livre requer privacidade na comunicação, bem como privacidade na busca e na associação." - Eric Hughes

2025-06-16 06:59:12Hello all :)
Something pretty exciting just happened in the world of decentralized tech.
A new social network project called Nostria successfully wrapped up its pre-seed funding round. It raised the funds through Angor, a crowdfunding platform built on Bitcoin and Nostr that aligns perfectly with the project’s decentralized mission.This post is all about what Nostria is doing, why it matters, and how Angor made it all possible.
What is Nostria?
nostr:npub16x7nxvehx0wvgy0sa6ynkw9c2ghuph3z0ll5t8veq3xwm8n9tqds6ka44x is a social network app that’s built to make the Nostr protocol easy to use. If you're not familiar with Nostr, it's an open protocol for decentralized social networking. It gives users more control and privacy, without relying on big platforms.
Nostria makes all that feel less like a tech experiment and more like a real social network. The app is simple, elegant, and beginner-friendly. It is available across iOS, Android, and web so you can jump in from anywhere.
Think of it as the easiest way to start using Nostr without needing to understand all the technical stuff under the hood.
https://www.nostria.app/assets/screenshots/nostria-01.jpg
The Problem Nostria is Solving:
One of the challenges Nostr faces right now is scaling. The network relies on relays to pass messages around, but many of these are centralized and getting overloaded. That creates serious bottlenecks and makes the whole experience less reliable. Just to give you an idea:
- Damus relay has around 646,000 users
- Nos relay has 601,000 users
- Snort sits at 417,000 users
When so many users depend on just a few relays, it puts a huge strain on the system and limits how far the network can grow.
Nostria’s Clever Fix
Nostria introduces a smarter way to scale Nostr without losing its decentralized core. Instead of relying on a few overloaded relays, it uses:
• Regionally deployed Discovery Relays – Think of these as local hubs placed in different parts of the world. When users connect, they are matched with a nearby relay, which keeps things faster and spreads the traffic out so no single relay gets overwhelmed.
• Pooled User Relays – Instead of each person depending on just one relay, users are connected through a shared pool. This means messages are sent and received more efficiently, especially when more people join the network.
All of this happens behind the scenes. The app keeps things simple and intuitive, with automation that handles the complexity for you. Whether you're posting, reading, or connecting with others, the experience stays smooth.
Nostria has bold ambitions. Here’s what they’re going for:
- A goal of 1 million daily active users
- Competing with platforms like Bluesky, Mastodon, and even X (formerly Twitter)
- A long-term plan to support both free and premium services to drive adoption
As of now, the Nostr network as a whole has:
- 15,000 daily active users
- 42.7 million total users
- 552 million total events
So the market is already there. It just needs the right tools to grow.
https://www.nostria.app/assets/screenshots/nostria-02.jpg
Meet the Team
Nostria is led by nostr:npub1zl3g38a6qypp6py2z07shggg45cu8qex992xpss7d8zrl28mu52s4cjajh, a software engineer with deep experience in distributed systems. He has been involved with the Nostr protocol since its early days in 2021 and is deeply passionate about decentralization and open-source tech.
https://www.nostria.app/assets/team/sondre.jpg
He’s joined by nostr:npub1e0krp2gr3l5nfd2jw2cydh68adxjpmcqdhs2e0jxkrqd4crwt4dslwrk0k, a thoughtful full-stack developer focused on simplicity and sovereignty, and nostr:npub10c4sn723akd7fqegfe6xntpq43p86vnyvv7j2ryaq8jzvhyea4pq72c5ul, a junior dev who’s already contributed to open source and is finishing up her studies.
https://www.nostria.app/assets/team/kosta.jpg https://www.nostria.app/assets/team/lu.jpg
The Funding Round
To bring Nostria to life, the team aimed to raise $30,000 during their pre-seed round. This funding would help them:
- Complete their MVP (Minimum Viable Product)
- Deploy global infrastructure
- Start building their user base
- Get ready for a full Seed round in late 2025
How Angor Helped?
Angor is a decentralized crowdfunding platform built on Bitcoin and the Nostr protocol. It’s designed exactly for projects like this. The team at Nostria launched their campaign on Angor between May 12 and May 31, and it was a success.
What made the campaign stand out?
- The whole process was decentralized and transparent.
- Backers could fund the project directly, without intermediaries.
- Nostria aligned perfectly with Angor’s vision of empowering projects that push decentralization forward.
The campaign served as both a fundraiser and a real-world example of how decentralized infrastructure can power decentralized ideas. And it worked.
Inside the Funding Terms
As part of this funding round, Nostria offered contributors a post-money SAFE (Simple Agreement for Future Equity). This is a modern, flexible way for startups to raise money early without the complexity of traditional equity rounds.
In simple terms:
•Investors contributed funds now, and in return, they will receive equity in Nostria during a future priced equity round. When Nostria raises its next round, most likely a Seed round, then those SAFE contributions will convert into actual shares.
•The SAFE includes a valuation cap, which sets a maximum company valuation for conversion. This guarantees that early backers receive shares at a better rate than future investors. While the exact cap isn't publicly listed, this feature ensures early supporters are rewarded for their trust.
•There is no interest or maturity date, which is a major benefit over traditional convertible notes. There’s no ticking clock or repayment obligation. Investors simply wait until the next funding event.
•The SAFE also features a Most Favored Nation (MFN) clause. This ensures that if the company issues another SAFE later with better terms, early investors will automatically receive the same improved terms. It’s designed to keep things transparent and equitable.
•Jurisdiction and legal terms: While the full legal text isn’t included in the note, SAFEs typically specify the legal jurisdiction governing the agreement. Nostria’s approach suggests a commitment to following standard legal frameworks, further underlining their seriousness and professionalism.
You can read Nostria’s public SAFE summary here: nostr:npub16x7nxvehx0wvgy0sa6ynkw9c2ghuph3z0ll5t8veq3xwm8n9tqds6ka44x
And you can view the full campaign hosted on Angor here: https://hub.angor.io/project/angor1qwdgxjuzhjykgpn5q8p3l2q9vyrgqdlrkfp5sjr
By sharing these details openly, the team added a strong layer of transparency and trust to the entire campaign. It is a clear signal that they are building something serious and thoughtful, with long-term commitment and care instead of shortcuts.
What’s Next?
With the funding secured, Nostria is sprinting ahead. The roadmap includes:
- June: Deploying media and relay servers
- July: Adding premium features and full cross-platform support
- August: Growing the user base and preparing for the next funding round
If all goes well, Nostria is on track to become one of the most accessible and user-friendly Nostr based platforms out there. With a clear roadmap and a team focused on long-term decentralization, the journey is just getting started...
Got an idea of your own? You can launch your project on Angor, just like Nostria did, and start your own funding round with the support of a like-minded community.
Thanks for reading. See y’all next week with another story from the world of open, decentralized innovation. Ciao

2025-06-17 17:47:48O protocolo Matrix é um sistema de comunicação descentralizado de código aberto que fornece uma plataforma para mensageiros descentralizados. O Element foi lançado em 2014 como uma implementação do protocolo Matrix, originalmente conhecido como Riot.im , A ideia do Element nasceu quando Matthew Hodgson e Amandine Le Pape, dois desenvolvedores de software, decidiram criar uma plataforma de comunicação aberta e segura, que permitisse aos usuários terem total controle sobre suas informações. Eles acreditavam que a internet deveria ser um lugar onde as pessoas pudessem se comunicar livremente, sem se preocupar com a privacidade de suas informações.
O Element é um aplicativo de chat gratuito e de código aberto disponível em várias plataformas, incluindo desktop, web e aplicativos móveis. Ele oferece criptografia de ponta a ponta, o que significa que as mensagens são protegidas e só podem ser lidas pelo remetente e pelo destinatário. Além disso, o Element é descentralizado, o que significa que ele não é controlado por uma única entidade, mas sim por uma rede global de servidores.
O Element é amplamente utilizado por indivíduos e empresas que desejam ter uma comunicação segura e privada. É frequentemente usado por equipes de projetos, organizações sem fins lucrativos e grupos ativistas que precisam compartilhar informações confidenciais e se comunicar de forma segura. O Element também é conhecido por seu recurso de salas públicas, que permite que os usuários se juntem a grupos de discussão sobre vários tópicos de interesse.
Uma das principais vantagens do Element é sua arquitetura descentralizada. Ao contrário das plataformas de mensagens convencionais que centralizam os dados em seus próprios servidores, o Element utiliza uma rede descentralizada, distribuindo as informações em diversos servidores espalhados pelo mundo. Isso significa que os dados dos usuários são menos suscetíveis a ataques cibernéticos e invasões, já que não são centralizados em um único ponto vulnerável.
Para usar o Element, normalmente os usuários precisam se registrar em um servidor Matrix. Existem várias opções disponíveis, incluindo servidores públicos e privados. No entanto, outra opção é criar um servidor próprio para usar o Element.
O Element também utiliza criptografia de ponta a ponta para proteger as mensagens e arquivos trocados entre os usuários. Isso significa que apenas o remetente e o destinatário das mensagens podem ler o conteúdo, garantindo que as informações permaneçam seguras e privadas.
Outra vantagem do Element é sua ampla variedade de recursos, incluindo videochamadas criptografadas, compartilhamento de tela e integração com outros serviços, como calendários e aplicativos de produtividade. Isso torna o Element uma plataforma completa de comunicação e colaboração, adequada para uso pessoal e empresarial.
O Element também é fácil de usar e possui uma interface intuitiva e personalizável. Os usuários podem personalizar a aparência do aplicativo e acessar diferentes configurações e recursos com apenas alguns cliques.

2025-06-16 06:25:50After almost 3 months of work, we've completed the redesign of kycnot.me. More modern and with many new features.
Privacy remains the foundation - everything still works with JavaScript disabled. If you enable JS, you will get some nice-to-have features like lazy loading and smoother page transitions, but nothing essential requires it.
User Accounts
We've introduced user accounts that require zero personal information:
- Secret user tokens - no email, no phone number, no personal data
- Randomly generated usernames for default privacy and fairness
- Karma system that rewards contributions and unlocks features: custom display names, profile pictures, and more.
Reviews and Community Discussions
On the previous sites, I was using third party open source tools for the comments and discussions. This time, I've built my own from scratch, fully integrated into the site, without JavaScript requirements.
Everyone can share their experiences and help others make informed decisions:
- Ratings: Comments can have a 1-5 star rating attached. You can have one rating per service and it will affect the overall user score.
- Discussions: These are normal comments, you can add them on any listed service.
Comment Moderation
I was strugling to keep up with moderation on the old site. For this, we've implemented an AI-powered moderation system that:
- Auto-approves legitimate comments instantly
- Flags suspicious content for human review
- Keeps discussions valuable by minimizing spam
The AI still can mark comments for human review, but most comments will get approved automatically by this system. The AI also makes summaries of the comments to help you understand the overall sentiment of the community.
Powerful Search & Filtering
Finding exactly what you need is now easier:
- Advanced filtering system with many parameters. You can even filter by attributes to pinpoint services with specific features.
The results are dynamic and shuffle services with identical scores for fairness.
See all listings
Listings are now added as 'Community Contributed' by default. This means that you can still find them in the search results, but they will be clearly marked as such.
Updated Scoring System
New dual-score approach provides more nuanced service evaluations:
- Privacy Score: Measures how well a service protects your personal information and data
-
Trust Score: Assesses reliability, security, and overall reputation
-
Combined into a weighted Overall Score for quick comparisons
- Completely transparent and open source calculation algorithm. No manual tweaking or hidden factors.
AI-Powered Terms of Service Analysis
Basically, a TLDR summary for Terms of Service:
- Automated system extracts the most important points from complex ToS documents

2025-06-17 17:46:21A sede do ProtonMail está localizada na Suíça, um país conhecido por suas leis rigorosas de privacidade, embora a empresa tenha enfrentado alguns desafios, como ataques DDoS e pressão do governo suíço, ela continua comprometida em fornecer um serviço seguro e privado aos seus usuários.
O ProtonMail foi fundado em 2014 por um grupo de cientistas do CERN (Organização Europeia para Pesquisa Nuclear) que queriam criar uma plataforma de e-mail segura e privada que usasse criptografia de ponta a ponta. O objetivo era oferecer aos usuários uma alternativa aos serviços de e-mail tradicionais que frequentemente violam a privacidade dos usuários.A equipe fundadora incluía Andy Yen, Jason Stockman e Wei Sun, todos com formação em física e matemática.
Ao longo dos anos, o ProtonMail lançou vários recursos adicionais, incluindo aplicativos móveis para iOS e Android, integração com Tor e a possibilidade de enviar e-mails criptografados para usuários de outros provedores de e-mail. O ProtonMail também lançou uma VPN (rede privada virtual) chamada ProtonVPN, que segue o mesmo compromisso com a privacidade e segurança dos usuários.
A criptografia de ponta a ponta utilizada pelo ProtonMail assegura a proteção de todas as mensagens de seus usuários. O processo de criptografia ocorre no dispositivo do remetente antes do envio das mensagens aos servidores da ProtonMail, onde elas são armazenadas em formato criptografado. Quando o destinatário abre a mensagem, ela é descriptografada no dispositivo do destinatário, garantindo que somente o destinatário possa ler o conteúdo da mensagem. Isso significa que, mesmo que os servidores da ProtonMail sejam violados, as mensagens dos usuários permanecerão seguras e protegidas.
O ProtonMail oferece suporte à autenticação de dois fatores usando chaves de segurança YubiKey. Isso adiciona uma camada extra de segurança ao login da conta do ProtonMail, pois um invasor precisaria não apenas da senha, mas também da chave física para acessar a conta do usuário. A YubiKey é uma opção popular para autenticação de dois fatores, pois é fácil de usar e oferece proteção adicional contra-ataques de phishing e keylogging. O ProtonMail também suporta outras opções de autenticação de dois fatores, aplicativos de autenticação, como o Aegis Authenticator.
Outra funcionalidade importante é a proteção contra phishing e spam. O ProtonMail utiliza algoritmos avançados de filtragem para identificar e bloquear mensagens maliciosas antes que elas cheguem à caixa de entrada do usuário. Isso ajuda a reduzir a quantidade de spam recebida e a proteger contra-ataques de phishing, que tentam enganar o usuário a fornecer informações pessoais.
Passo a passo instalação do aplicativo protonmail no Android:
-
Baixe e instale o aplicativo protonmail em seu dispositivo móvel no F-droid ou obtainium.
-
Clique em "Criar nova conta" se você ainda não tiver uma conta ProtonMail, ou clique em "Fazer login" se já tiver uma conta.
-
Se você está criando uma nova conta, preencha os campos de registro, incluindo seu endereço de e-mail desejado e uma senha forte.
-
Depois de criar ou fazer login em sua conta, você pode usar o ProtonMail em seu dispositivo Android para enviar e receber e-mails seguros e protegidos.
Lembre-se de que, para garantir a privacidade e a segurança de suas informações, é importante usar uma senha forte e habilitar a autenticação de dois fatores. Utilize o Tor para acessar seu e-mail no site onion e considere usar uma VPN.
No Relatório de Transparência do ProtonMail, em muitos casos, a única informação que eles puderam fornecer foi um e-mail de recuperação (opcional na criação da conta) ou o IP que acessou o e-mail.
A própria ProtonMail recomenda o uso do Tor para acesso anônimo ao serviço. Se um juiz exigir a coleta do seu IP, a Proton não terá essa informação se você acessar seu e-mail via o site onion pelo Tor.
Se você é uma pessoa em situação de risco, como um ativista ou alguém que pode ser perseguido por diversos motivos, é essencial tomar medidas excepcionais: 1. Pague pelo serviço com Bitcoin. 2. Não use informações que possam identificá-lo ao se registrar. 3. Utilize o Tor, ou uma VPN, sempre que acessar o ProtonMail.

2025-06-17 17:08:15Bitcoin surgiu como uma alternativa ao sistema financeiro tradicional, oferecendo um meio de troca descentralizado e resistente à censura. No entanto, essa proposta desafia diretamente o controlo que os governos exercem sobre a economia, especialmente no que diz respeito à emissão de moeda e regulação do setor financeiro. Como resultado, muitos governos veem Bitcoin com desconfiança e tentam limitar a sua adoção, enquanto outros procuram integrá-lo à economia de forma controlada.
Motivos para o conflito entre governos e Bitcoin
A resistência governamental à adoção de Bitcoin deve-se a vários fatores, entre os quais se destacam:
Perda de controlo monetário: Os governos controlam a política monetária através da emissão de moeda fiduciária e da manipulação das taxas de juro. Bitcoin, por ter uma oferta fixa e descentralizada, impede que governos imprimam mais dinheiro, limitando a sua influência sobre a economia.
Dificuldade na tributação: A utilização de Bitcoin dificulta a fiscalização de transações e a cobrança de impostos, tornando-se um desafio para as autoridades que dependem da tributação para financiar gastos públicos.
Preocupações com regulação e crime financeiro: Muitos governos argumentam que Bitcoin pode ser usado para lavagem de dinheiro, evasão fiscal e outras atividades ilícitas. No entanto, como todas as transações ficam registadas na blockchain ou timechain, Bitcoin é, na realidade, mais rastreável do que o dinheiro físico.
Competição com moedas digitais de bancos centrais (CBDCs): Alguns governos estão a desenvolver as suas próprias moedas digitais, conhecidas como CBDCs. Estas oferecem um alto nível de controlo sobre as transações financeiras, mas não possuem as mesmas propriedades descentralizadas de Bitcoin. Para garantir a adoção das CBDCs, alguns governos tentam limitar ou proibir o uso de Bitcoin.
Diferentes países têm abordagens variadas em relação a Bitcoin, desde a aceitação total até a repressão severa.
El Salvador: foi o primeiro país a adotar Bitcoin como moeda legal em 2021. Esta decisão gerou conflitos com instituições financeiras globais, como o Fundo Monetário Internacional (FMI), que pressionou o governo salvadorenho a reconsiderar a sua decisão.
China: o governo chinês proibiu completamente a mineração e o uso de Bitcoin em 2021, alegando preocupações ambientais e riscos financeiros. No entanto, muitos mineradores e utilizadores chineses continuam a operar através de meios alternativos.
Estados Unidos: embora Bitcoin seja legal nos EUA, o governo tem imposto regulamentações mais rígidas às plataformas de troca e à mineração, tentando aumentar o controlo sobre o setor. Alguns políticos defendem uma abordagem favorável, enquanto outros veem Bitcoin como uma ameaça ao dólar.
União Europeia: a UE tem adotado uma postura regulatória mais rigorosa, impondo regras sobre a identificação dos utilizadores e a transparência das transações. Apesar disso, Bitcoin continua a ser legal e amplamente utilizado.
Apesar dos desafios impostos por alguns governos, a adoção de Bitcoin continua a crescer. Muitos utilizadores veem Bitcoin como uma forma de preservar a sua riqueza perante políticas monetárias inflacionárias e controlo excessivo sobre o dinheiro. Além disso, países com economias instáveis e sistemas financeiros pouco acessíveis encontram em Bitcoin uma solução para pagamentos internacionais e proteção contra crises económicas.
A resistência dos governos pode desacelerar a adoção de Bitcoin em algumas regiões, mas não conseguirá eliminá-lo completamente. Como uma rede descentralizada e global, Bitcoin continuará a ser utilizado, independentemente das restrições impostas por qualquer governo. A longo prazo, a sua adoção dependerá da capacidade dos indivíduos e empresas de resistirem às pressões regulatórias e continuarem a utilizá-lo como uma alternativa financeira.
Resumindo, o conflito entre governos e Bitcoin reflete a luta entre um sistema financeiro tradicional centralizado e uma nova alternativa descentralizada. Enquanto alguns países tentam proibir ou restringir o seu uso, outros adotam-no como parte da sua economia. No final, a resistência dos governos pode apenas atrasar, mas dificilmente impedirá a adoção global de Bitcoin, que continua a demonstrar a sua resiliência e utilidade como uma reserva de valor e meio de troca.
Muito obrigado por teres lido o texto até aqui, espero que esteja tudo bem contigo e um abraço enorme do teu madeirense bitcoiner maximalista favorito. Viva a liberdade!

2025-06-16 06:01:49CANNES, FRANCE – May 2025 — Bitcoin mining made its mark at the world’s most prestigious film gathering this year as Puerto Rican director and producer Alana Mediavilla introduced her feature documentary Dirty Coin: The Bitcoin Mining Documentary at the Marché du Film during the Cannes Film Festival.
The film puts bitcoin mining at the center of a rising global conversation about energy, technology, and economic freedom.
Dirty Coin is the first feature-length documentary to explore bitcoin mining through immersive, on-the-ground case studies.
From rural towns in the United States to hydro-powered sites in Latin America and the Congo, the film follows miners and communities navigating what may be one of the most misunderstood technologies of our time.
The result is a human-centered look at how bitcoin mining is transforming local economies and energy infrastructure in real ways.
To mark its Cannes debut, Mediavilla and her team hosted a packed industry event that brought together leaders from both film and finance.
Dirty Coin debut ceremony at the Marché du Film
Sponsors Celestial Management, Sangha Renewables, Nordblock, and Paystand.org supported the program, which featured panels on mining, energy use, and decentralized infrastructure.
Attendees had the rare opportunity to engage directly with pioneers in the space. A special session in French led by Seb Gouspillou spotlighted mining efforts in the Congo’s Virunga region.
Dirty Coin builds on Mediavilla’s award-winning short film Stranded, which won over 20 international prizes, including Best Short Documentary at Cannes in 2024.
That success helped lay the foundation for the feature and positioned Mediavilla as one of the boldest new voices in global documentary filmmaking.
Alana Mediavilla speaks at the Marché du Film — Cannes Film Festival
“If we’ve found an industry that can unlock stranded energy and turn it into real power for people—especially in regions with energy poverty—why wouldn’t we look into it?” says Mediavilla. “Our privilege blinds us.
“The same thing we criticize could be the very thing that lifts the developing world to our standard of living. Ignoring that potential is a failure of imagination.”
Much like the decentralized network it explores, Dirty Coin is spreading globally through grassroots momentum.
Local leaders are hosting independent screenings around the world, from Roatán and Berlin to São Paulo and Madrid. Upcoming events include Toronto and Zurich, with more cities joining each month.
Mediavilla, who previously worked in creative leadership roles in the U.S. — including as a producer at Google — returned to Puerto Rico to found Campo Libre, a studio focused on high-caliber, globally relevant storytelling from the Caribbean.
She was also accepted into the Cannes Producers Network, a selective program open only to producers with box office releases in the past four years.
Mediavilla qualified after independently releasing Dirty Coin in theaters across Puerto Rico. Her participation in the network gave her direct access to meetings, insights, and connections with the most active distributors and producers working today.
The film’s next public screening will take place at the Anthem Film Festival in Palm Springs on Saturday, June 14 at 2 PM. Additional screenings and market appearances are planned throughout the year at Bitcoin events and international film platforms.

2025-06-16 00:58:00THIS IS IMPORTANT!!!
After the wave of word-scrambling spam bots, a new and very problematic kind of spam has arrived in the Nostr. Whenever you post something now, you will get gay porn videos as an automated answer (No, being gay itself is not problematic!!!). To get rid of all the automated spam, remove the following relays from your inbox and outbox relay list: - nos.lol - relay.damus.io - nostr.oxtr.dev - relay.primal.net
As long as you have even one of these relays in your inbox and outbox lists, you and your followers will be spammed whenever posting something.
It is unknown if the bots only reply to kind 1 events or to all events.

Sup, freaks? Your Uncle Marty did a little vibe coding a couple months ago and that vibe coding project has turned into an actual product that is live in the Google Chrome web store and will soon to be live in the Firefox add-on store as well. It's called Opportunity Cost and it is an extension that enables you to price the internet in Bitcoin.
[
Opportunity Cost – See Prices in Bitcoin Instantly
Convert USD prices to Bitcoin (satoshis) as you browse. Dual display, privacy-first, and open source.
Opportunity CostTFTC
](https://www.opportunitycost.app/?ref=tftc.io)
Check it out!
This whole process has been extremely rewarding to me for many reasons. The first of which is that I've had many ideas in the past to launch a product focused on bitcoin education that simply never left my brain because I never felt comfortable paying a developer to go out and build a product that I wasn't sure would ultimately get product market fit.
Due to the advancements of AI, particularly ChatGPT and Replit, I was able to spend a few hours on a Saturday vibe coding a prototype for Opportunity Cost. It worked. I side loaded it into Chrome and Firefox, tested it out for a few days and decided, "Hey, I think this is something that's worthwhile and should be built."
Backtracking just a little bit, the initial idea for this app was to create an AR application that would enable you to take pictures of goods in the real world and have their prices automatically converted to bitcoin so that you could weigh the opportunity cost of whether or not you actually wanted to buy that good or decide to save in bitcoin instead. With the help of Justin Moon from the Human Rights Foundation and Anthony Ronning from OpenSecret and Maple AI, I was pointed in the right direction of vibe coding tools I could use to build a simple MVP. I took their advice, built the MVP, and demoed it at the Bitcoin Park Austin weekly AI meetup in mid-April.
The next week, I was talking with a friend, Luke Thomas, about the idea and during our conversation he made a simple quip, "You should make a Chrome extension. I really want a Chrome extension that does this." And that's what sent me down the vibe coding rabbit hole that Saturday which led to the prototype.
After I was comfortable with and confident in the prototype, I found a young hungry developer by the name of Moses on Nostr, I reached out to him, told him my idea, showed him the prototype and asked if he thought he could finish the application for me. He luckily agreed to do so and within a couple of weeks we had a fully functioning app that was officially launched today. We're about 12 hours into the launch and I must say that I'm pleasantly surprised with the reception from the broader Bitcoin community. It seems like something that people are happy exists and I feel extremely happy that people see some value in this particular application.
Now that you have the backstory, let's get into why I think something like Opportunity Cost should exist. As someone who's been writing a newsletter and producing podcasts about bitcoin for eight years in an attempt to educate individuals from around the world about what bitcoin is, why it's important, and how they can leverage it, I've become convinced that a lot of the work that needs to be done still exists at the top of the funnel. You can scream at people. You can grab them by the shoulders. You can shake them. You can remind them at Thanksgiving that if they had listened to your advice during any Thanksgiving in the previous years they would be better off financially. But at the end of the day most people don't listen. They need to see things. Seeing things for yourself is a much more effective teaching mechanism than be lectured to by someone else.
My hope with Opportunity Cost is that it catches the eye of some bitcoin skeptics or individuals who may be on the cusp of falling down the bitcoin rabbit hole and they see the extension as a way to dip their toes into bitcoin to get a better understanding of the world by pricing the goods and services they purchase on a day-to-day month-to-month and year-to-year basis in bitcoin without having to download a wallet or set up an exchange account. The tippy top of the bitcoin marketing funnel.
That is not all though. I think Opportunity Cost can serve individuals at both ends of the funnel. That's why it's pretty exciting to me. It's as valuable to the person who is bitcoin curious and looking to get a better understanding as it is to the hardcore bitcoiner living on a bitcoin standard who is trying to get access to better tools that enable him to get a better grasp of their spending in bitcoin terms.
Lastly, after playing around with it for a few days after I built the prototype, I realized that it has incredible memetic potential. Being able to take a screenshot of goods that people are buying on a day-to-day basis, pricing them in bitcoin and then sharing them on social media is very powerful. Everything from houses to junk items on Amazon to the salaries of pro athletes to your everyday necessities. Seeing the value of those things in bitcoin really makes you think.
One day while I was testing the app, I tried to see how quickly I could find goods on the internet that cumulatively eclipsed the 21 million supply cap limit of bitcoin. To my surprise, even though I've been in bitcoin for 12 years now, it did not take me that long. The opportunity cost of everything I buy on a day-to-day basis becomes very clear when using the extension. What's even clearer is the fact that Bitcoin is completely mispriced at current levels. There is so much winning ahead of us.
Also, it's probably important to note that the extension is completely open source. You can check out our GitHub page here. Submit pull requests. Suggest changes to the app.
We've also tried to make Opportunity Cost as privacy preserving as possible. Everything within the extension happens in your browser. The only external data that we're providing is the bitcoin to fiat price conversion at any given point in time. We're not data harvesting the web pages you're browsing or the items you're looking at. We're not collecting data and sending it to third party marketers. We want to align ourselves with the open and permissionless nature of bitcoin while also preserving our users' privacy. We're not trying to monetize this in that way. Though, I will say that I'm thinking of ways to monetize Opportunity Cost if it does gain significant traction, but I promise it will be in a way that respects your privacy and is as unobtrusive as possible. We'll see how it goes.
Thank you for coming to my TED talk. Please download and use the extension. Let us know what you think.

2025-06-17 17:01:38BlackRock’s iShares Bitcoin Trust (IBIT) has become the fastest exchange-traded fund (ETF) to ever reach $70 billion in assets under management (AUM).
The fund, which launched in January 2024, hit this milestone in just 341 trading days—five times faster than the previous record-holder, the SPDR Gold Shares ETF (GLD), which took 1,691 days to reach the same mark.
IBIT now holds over 662,000 BTC — iShares
Bloomberg ETF analyst Eric Balchunas tweeted on June 9, “IBIT just blew through $70 billion and is now the fastest ETF to ever hit that mark in only 341 days.” This is a big deal and shows bitcoin is going mainstream.
IBIT has beaten fastest growing ETFs in history — Eric Balchunas on X
The fund’s rapid growth means institutional investors are embracing bitcoin at scale.
The fund has $71.9 billion in AUM and holds over 662,000 bitcoin. This makes BlackRock the largest institutional bitcoin holder in the world. To put that in perspective, the fund holds more bitcoin than Binance or Michael Saylor’s Strategy.
“IBIT’s growth is unprecedented,” said Bloomberg analyst James Seyffart. “It’s the fastest ETF to reach most milestones, faster than any other ETF in any asset class.”
BlackRock’s bitcoin ETF isn’t just big. It’s also greatly outperforming other spot bitcoin ETFs launched at the same time. BlackRock’s brand and global client base gave the fund instant credibility.
Many institutional investors want a regulated and convenient way to get into bitcoin without holding the asset directly, and this fund has made it easy for them to invest.
Robert Mitchnick, BlackRock’s head of digital assets, told Yahoo Finance that bitcoin’s rising status as an inflation hedge and alternative store of value is driving IBIT’s popularity.
He explained bitcoin is becoming an inflation hedge and alternative store of value and that’s what’s driving the growth.
Eric Balchunas also noted that when BlackRock filed for IBIT, bitcoin was at $30,000 and there was still skepticism after the FTX blowup. Now that bitcoin is at $110,000, it is “seen as legitimate for other big investors.”
Institutional demand for bitcoin has never been stronger, with IBIT making up nearly 20% of all bitcoin held by public companies, private firms, governments, exchanges and decentralized finance platforms.
That dominance may soon be challenged as public companies prepare to buy more bitcoin and shake up the current supply distribution.
Matthew Sigel, VanEck’s head of digital assets research, shared data that six public companies plan to raise, or have raised, up to $76 billion to buy bitcoin. That’s more than half of the spot Bitcoin ETF industry’s current AUM, so there’s clearly interest beyond ETFs.
On the broader market, IBIT’s rise coincided with bitcoin’s price surge to new highs above $110,000. The inflows reflect investors’ confidence in Bitcoin’s future and desire for regulated exposure through traditional products.
It’s worth mentioning that IBIT also had over $1 billion in volume on its first day of trading. It’s now the largest ETF in BlackRock’s lineup, even bigger than gold funds and other popular ETFs tracking international equities.

2025-06-15 20:01:53The former seems to have found solid product market fit. Expect significant volume, adoption, and usage going forward.
The latter's future remains to be seen. Dependence on Tor, which has had massive reliability issues, and lack of strong privacy guarantees put it at risk.
— ODELL (@ODELL) October 27, 2022
The Basics
- Lightning is a protocol that enables cheap and fast native bitcoin transactions.
- At the core of the protocol is the ability for bitcoin users to create a payment channel with another user.
- These payment channels enable users to make many bitcoin transactions between each other with only two on-chain bitcoin transactions: the channel open transaction and the channel close transaction.
- Essentially lightning is a protocol for interoperable batched bitcoin transactions.
- It is expected that on chain bitcoin transaction fees will increase with adoption and the ability to easily batch transactions will save users significant money.
- As these lightning transactions are processed, liquidity flows from one side of a channel to the other side, on chain transactions are signed by both parties but not broadcasted to update this balance.
- Lightning is designed to be trust minimized, either party in a payment channel can close the channel at any time and their bitcoin will be settled on chain without trusting the other party.
There is no 'Lightning Network'
- Many people refer to the aggregate of all lightning channels as 'The Lightning Network' but this is a false premise.
- There are many lightning channels between many different users and funds can flow across interconnected channels as long as there is a route through peers.
- If a lightning transaction requires multiple hops it will flow through multiple interconnected channels, adjusting the balance of all channels along the route, and paying lightning transaction fees that are set by each node on the route.
Example: You have a channel with Bob. Bob has a channel with Charlie. You can pay Charlie through your channel with Bob and Bob's channel with User C.
- As a result, it is not guaranteed that every lightning user can pay every other lightning user, they must have a route of interconnected channels between sender and receiver.
Lightning in Practice
- Lightning has already found product market fit and usage as an interconnected payment protocol between large professional custodians.
- They are able to easily manage channels and liquidity between each other without trust using this interoperable protocol.
- Lightning payments between large custodians are fast and easy. End users do not have to run their own node or manage their channels and liquidity. These payments rarely fail due to professional management of custodial nodes.
- The tradeoff is one inherent to custodians and other trusted third parties. Custodial wallets can steal funds and compromise user privacy.
Sovereign Lightning
- Trusted third parties are security holes.
- Users must run their own node and manage their own channels in order to use lightning without trusting a third party. This remains the single largest friction point for sovereign lightning usage: the mental burden of actively running a lightning node and associated liquidity management.
- Bitcoin development prioritizes node accessibility so cost to self host your own node is low but if a node is run at home or office, Tor or a VPN is recommended to mask your IP address: otherwise it is visible to the entire network and represents a privacy risk.
- This privacy risk is heightened due to the potential for certain governments to go after sovereign lightning users and compel them to shutdown their nodes. If their IP Address is exposed they are easier to target.
- Fortunately the tools to run and manage nodes continue to get easier but it is important to understand that this will always be a friction point when compared to custodial services.
The Potential Fracture of Lightning
- Any lightning user can choose which users are allowed to open channels with them.
- One potential is that professional custodians only peer with other professional custodians.
- We already see nodes like those run by CashApp only have channels open with other regulated counterparties. This could be due to performance goals, liability reduction, or regulatory pressure.
- Fortunately some of their peers are connected to non-regulated parties so payments to and from sovereign lightning users are still successfully processed by CashApp but this may not always be the case going forward.
Summary
- Many people refer to the aggregate of all lightning channels as 'The Lightning Network' but this is a false premise. There is no singular 'Lightning Network' but rather many payment channels between distinct peers, some connected with each other and some not.
- Lightning as an interoperable payment protocol between professional custodians seems to have found solid product market fit. Expect significant volume, adoption, and usage going forward.
- Lightning as a robust sovereign payment protocol has yet to be battle tested. Heavy reliance on Tor, which has had massive reliability issues, the friction of active liquidity management, significant on chain fee burden for small amounts, interactivity constraints on mobile, and lack of strong privacy guarantees put it at risk.

2025-06-17 17:01:17The Present Ecosystem It Is Not Just Calls
The role of telecommunications carriers has long since evolved beyond that of simple call connectors. Currently, they serve as actual digital centers that penetrate practically every facet of our interconnected lives. With more than 5.7 billion mobile service subscribers and 4.7 billion mobile internet users worldwide (roughly 58% of the global population), telecommunications are the foundation of the digital economy. It is anticipated that by 2030, this figure will rise to an astounding 5.5 billion mobile internet users, or 64% of the world’s population.
A variety of connectivity options are available in the current telecommunications ecosystem, ranging from home fiber optics to 5th generation of mobile networks, which is expected to be adopted globally by 57% by 2030, creating roughly 5.3 billion connections. Collaborations with streaming services that provide on-demand entertainment.
Current Telecom Ecosystem
From fiber optics to 5G technology, telecommunications companies have focused on diversifying global connectivity. By 2030, they are expected to reach 57% global adoption, resulting in around 5.3 billion connections.
There are partnerships with streaming platforms that have transformed carriers into true content gateways. This has helped the explosive growth of data traffic, which reached the mark of 26.53 exabytes per month in 2018.
These companies are offering some personalized business services, such as IoT, security and cloud solutions.
Furthermore, many carriers already provide basic financial services like mobile payments and device financing. This last one is the perfect starting point for a further revolution: the integration of Bitcoin into the telecom ecosystem.
Telecommunications and Bitcoin: A Perfect Match
Carriers’ use of Bitcoin is a radical rethinking of the business-customer relationship, not merely a new mode of payment. Here is how this new ecosystem could work:
-
Customer Experience and Infrastructure – Before implementing Bitcoin, an carrier must build the necessary infrastructure. This entails creating mechanisms that may not only receive cryptocurrency payments but alsoIf companies want to lessen their exposure to volatility, they can automatically convert Bitcoin to fiat money. Companies can also easily integrate with current invoicing systems and provide a more straightforward user experience.
Imagine launching the app for your carrier, scanning a QR code, and having your bill paid or your monthly plan renewed in a matter of seconds. Without waiting for business days, without banking middlemen, and without exorbitant costs.
-
Bringing in New Segments – In addition to making life easier for current clients, Bitcoin’s acceptance draws in entirely new demographics:
Those that appreciate innovation and wish to back trailblazing businesses are known as technology enthusiasts.
Advocates for privacy: Customers who favor transactions that need less personal information to be shared
Global clientele are tourists from other countries who can pay for services without worrying about regional restrictions or exchange rates.Carrier might develop targeted marketing, such as “early access to new devices for customers who use cryptocurrencies” or “10% discount on data top-ups when paid with Bitcoin,” to attract these demographics.
Ongoing Innovation: What Will Happen After Bitcoin?
When businesses embrace Bitcoin and fully utilize blockchain technology, the real revolution will take place. This strategy creates opportunities for developments like:
- Creative Smart Contracts – Smart contracts are self-executing, blockchain-based programs that eliminate middlemen and automate processes. This could be interpreted by carriers as:
- Instant service activation – Your Bitcoin payment has been validated and your international data package is activated automatically even before you land at the airport.Contracts that automatically expire at the designated time eliminate the need for a constant call to the call center.
- Simplified termination – Mini-smart contracts enable family members to automatically transfer excess mobile data.
This was recently illustrated by the Japanese carrier Rakuten Mobile, which unveiled a system that enables users to temporarily increase their bandwidth through smart contracts for a few hours (for instance, to broadcast live events) without modifying their primary plan.
- Creative Partnerships in the World Ecosystem – The carriers are able to establish strategic alliances with:
- Fintech companies that specialize in bitcoin to create integrated digital wallets.
- Startups creating telecom-specific decentralized applications (DApps).
- Academic institutions will investigate novel applications of blockchain technology in the telecommunications sector.
Given that the market is dominated by industry titans like China Mobile (794 million subscribers in 2023), Verizon (US$ 133.97 billion in 2023), and AT&T (US$ 161.5 billion in revenue in 2022), these partnerships have the potential to accelerate disruptive innovations that benefit the entire telecommunications ecosystem.
Reimagining the Customer Relationship with New Business Models
The incorporation of Bitcoin enables the investigation of business ideas that were before unfeasible:
- Microtransactions: Only Paying for the Things You Use – Processing fees in the traditional financial system make it impossible to charge tiny sums. This issue is resolved by Bitcoin, particularly via the Lightning Network, which permits:
- Payment per call second (think of paying R$0.001 per second for just the actual usage)
- – Acquiring small data packages (e.g., 500MB for a single movie)
- – Immediate access to high-quality WiFi networks at cafes or airports, with just the time spent connecting being charged,
The startup Althea Network, which enables communities to establish their own internet networks where users automatically pay for each byte consumed, is already testing this idea. The trend of increasing video traffic, which currently makes up 70% of all mobile data traffic and is predicted to reach 80% by 2028, is well aligned with this strategy.
- Loyalty Initiatives on the Blockchain: Conventional point systems have little transparency and are hard to use. A method based on blockchain can:
Make loyalty tokens that are equivalent to actual digital money.
Permit customer exchanges (you can trade or sell points you won’t use).
Form more extensive alliances wherein other businesses accept the carrier tokens.A system where users earn blockchain-based “T-points” tokens that can be turned into modest amounts of Bitcoin or swapped for other services is already being tested by South Korean carrier SK Telecom. In South Korea, one of the top markets for the adoption of 5G worldwide, this kind of innovation is especially pertinent.
Obstacles and Realistic Implementation Considerations
Despite the vast potential, there are important issues that must be resolved:
- Evolutionary Regulation – Countries’ cryptocurrency regulations differ greatly from one another and are always evolving. Carriers will require:
- Maintain specialized teams to keep an eye on regulatory developments, work with authorities to help create reasonable regulations, and create adaptable systems that can evolve to meet new needs.
- This strategy is crucial in light of the fact that the telecom industry is already dealing with a lot of regulatory pressure in different jurisdictions, as demonstrated by the Canadian government’s recent initiatives to encourage more access to MVNOs (mobile virtual network carriers) in 2023.
- Please read this to undertand how Governors don’t do anything to help you.
- Financial Management and Volatility – One difficulty is the volatility of Bitcoin pricing. In order to reduce hazards, carriers can:
- Convert a portion of payments into fiat money automatically.
Employ hedge services to guard against sharp swings.
Provide dynamic prices that change based on the state of the market. - Given that international carriers oversee yearly earnings in the hundreds of billions of dollars, these tactics are particularly pertinent.
- Convert a portion of payments into fiat money automatically.
- Education of Consumers – Many customers are still confused about cryptocurrencies. Strategies that work include:
- The carrier app’s simplified instructional
- Committed assistance for Bitcoin transactions
- Rewards for initial cryptocurrency purchases
With more than 5.7 billion mobile consumers worldwide, this educational initiative has the potential to significantly accelerate the widespread acceptance of cryptocurrencies.
Now is the time for deep digital transformation
Telecommunications companies that incorporate blockchain and Bitcoin into their ecosystem are doing more than simply introducing a new payment method; they are putting themselves at the vanguard of a significant digital revolution that will keep up with the industry’s explosive growth, which is expected to reach US$ 1.3 trillion globally by 2028.
The ability to innovate services, draw in creative clients, and open up new markets will be available to those that welcome this shift, which the conventional model would not allow. In order to prepare the infrastructure for this revolution, more than 300 commercial 5G networks will be operational globally beginning in 2024, marking the beginning of this shift.
As customers, we may anticipate more individualized, open, and effective services. Our civilization is progressing toward a telecommunications infrastructure that is fully suited to the digital era and capable of handling the enormous amount of data traffic

2025-06-17 16:40:28The new website is finally live! I put in a lot of hard work over the past months on it. I'm proud to say that it's out now and it looks pretty cool, at least to me!
Why rewrite it all?
The old kycnot.me site was built using Python with Flask about two years ago. Since then, I've gained a lot more experience with Golang and coding in general. Trying to update that old codebase, which had a lot of design flaws, would have been a bad idea. It would have been like building on an unstable foundation.
That's why I made the decision to rewrite the entire application. Initially, I chose to use SvelteKit with JavaScript. I did manage to create a stable site that looked similar to the new one, but it required Jav aScript to work. As I kept coding, I started feeling like I was repeating "the Python mistake". I was writing the app in a language I wasn't very familiar with (just like when I was learning Python at that mom ent), and I wasn't happy with the code. It felt like spaghetti code all the time.
So, I made a complete U-turn and started over, this time using Golang. While I'm not as proficient in Golang as I am in Python now, I find it to be a very enjoyable language to code with. Most aof my recent pr ojects have been written in Golang, and I'm getting the hang of it. I tried to make the best decisions I could and structure the code as well as possible. Of course, there's still room for improvement, which I'll address in future updates.
Now I have a more maintainable website that can scale much better. It uses a real database instead of a JSON file like the old site, and I can add many more features. Since I chose to go with Golang, I mad e the "tradeoff" of not using JavaScript at all, so all the rendering load falls on the server. But I believe it's a tradeoff that's worth it.
What's new
- UI/UX - I've designed a new logo and color palette for kycnot.me. I think it looks pretty cool and cypherpunk. I am not a graphic designer, but I think I did a decent work and I put a lot of thinking on it to make it pleasant!
- Point system - The new point system provides more detailed information about the listings, and can be expanded to cover additional features across all services. Anyone can request a new point!
- ToS Scrapper: I've implemented a powerful automated terms-of-service scrapper that collects all the ToS pages from the listings. It saves you from the hassle of reading the ToS by listing the lines that are suspiciously related to KYC/AML practices. This is still in development and it will improve for sure, but it works pretty fine right now!
- Search bar - The new search bar allows you to easily filter services. It performs a full-text search on the Title, Description, Category, and Tags of all the services. Looking for VPN services? Just search for "vpn"!
- Transparency - To be more transparent, all discussions about services now take place publicly on GitLab. I won't be answering any e-mails (an auto-reply will prompt to write to the corresponding Gitlab issue). This ensures that all service-related matters are publicly accessible and recorded. Additionally, there's a real-time audits page that displays database changes.
- Listing Requests - I have upgraded the request system. The new form allows you to directly request services or points without any extra steps. In the future, I plan to enable requests for specific changes to parts of the website.
- Lightweight and fast - The new site is lighter and faster than its predecessor!
- Tor and I2P - At last! kycnot.me is now officially on Tor and I2P!
How?
This rewrite has been a labor of love, in the end, I've been working on this for more than 3 months now. I don't have a team, so I work by myself on my free time, but I find great joy in helping people on their private journey with cryptocurrencies. Making it easier for individuals to use cryptocurrencies without KYC is a goal I am proud of!
If you appreciate my work, you can support me through the methods listed here. Alternatively, feel free to send me an email with a kind message!
Technical details
All the code is written in Golang, the website makes use of the chi router for the routing part. I also make use of BigCache for caching database requests. There is 0 JavaScript, so all the rendering load falls on the server, this means it needed to be efficient enough to not drawn with a few users since the old site was reporting about 2M requests per month on average (note that this are not unique users).
The database is running with mariadb, using gorm as the ORM. This is more than enough for this project. I started working with an
sqlite
database, but I ended up migrating to mariadb since it works better with JSON.The scraper is using chromedp combined with a series of keywords, regex and other logic. It runs every 24h and scraps all the services. You can find the scraper code here.
The frontend is written using Golang Templates for the HTML, and TailwindCSS plus DaisyUI for the CSS classes framework. I also use some plain CSS, but it's minimal.
The requests forms is the only part of the project that requires JavaScript to be enabled. It is needed for parsing some from fields that are a bit complex and for the "captcha", which is a simple Proof of Work that runs on your browser, destinated to avoid spam. For this, I use mCaptcha.

2025-06-17 16:40:27Know Your Customer is a regulation that requires companies of all sizes to verify the identity, suitability, and risks involved with maintaining a business relationship with a customer. Such procedures fit within the broader scope of anti-money laundering (AML) and counterterrorism financing (CTF) regulations.
Banks, exchanges, online business, mail providers, domain registrars... Everyone wants to know who you are before you can even opt for their service. Your personal information is flowing around the internet in the hands of "god-knows-who" and secured by "trust-me-bro military-grade encryption". Once your account is linked to your personal (and verified) identity, tracking you is just as easy as keeping logs on all these platforms.
Rights for Illusions
KYC processes aim to combat terrorist financing, money laundering, and other illicit activities. On the surface, KYC seems like a commendable initiative. I mean, who wouldn't want to halt terrorists and criminals in their tracks?
The logic behind KYC is: "If we mandate every financial service provider to identify their users, it becomes easier to pinpoint and apprehend the malicious actors."
However, terrorists and criminals are not precisely lining up to be identified. They're crafty. They may adopt false identities or find alternative strategies to continue their operations. Far from being outwitted, many times they're several steps ahead of regulations. Realistically, KYC might deter a small fraction – let's say about 1% ^1 – of these malefactors. Yet, the cost? All of us are saddled with the inconvenient process of identification just to use a service.
Under the rhetoric of "ensuring our safety", governments and institutions enact regulations that seem more out of a dystopian novel, gradually taking away our right to privacy.
To illustrate, consider a city where the mayor has rolled out facial recognition cameras in every nook and cranny. A band of criminals, intent on robbing a local store, rolls in with a stolen car, their faces obscured by masks and their bodies cloaked in all-black clothes. Once they've committed the crime and exited the city's boundaries, they switch vehicles and clothes out of the cameras' watchful eyes. The high-tech surveillance? It didn’t manage to identify or trace them. Yet, for every law-abiding citizen who merely wants to drive through the city or do some shopping, their movements and identities are constantly logged. The irony? This invasive tracking impacts all of us, just to catch the 1% ^1 of less-than-careful criminals.
KYC? Not you.
KYC creates barriers to participation in normal economic activity, to supposedly stop criminals. ^2
KYC puts barriers between many users and businesses. One of these comes from the fact that the process often requires multiple forms of identification, proof of address, and sometimes even financial records. For individuals in areas with poor record-keeping, non-recognized legal documents, or those who are unbanked, homeless or transient, obtaining these documents can be challenging, if not impossible.
For people who are not skilled with technology or just don't have access to it, there's also a barrier since KYC procedures are mostly online, leaving them inadvertently excluded.
Another barrier goes for the casual or one-time user, where they might not see the value in undergoing a rigorous KYC process, and these requirements can deter them from using the service altogether.
It also wipes some businesses out of the equation, since for smaller businesses, the costs associated with complying with KYC norms—from the actual process of gathering and submitting documents to potential delays in operations—can be prohibitive in economical and/or technical terms.
You're not welcome
Imagine a swanky new club in town with a strict "members only" sign. You hear the music, you see the lights, and you want in. You step up, ready to join, but suddenly there's a long list of criteria you must meet. After some time, you are finally checking all the boxes. But then the club rejects your membership with no clear reason why. You just weren't accepted. Frustrating, right?
This club scenario isn't too different from the fact that KYC is being used by many businesses as a convenient gatekeeping tool. A perfect excuse based on a "legal" procedure they are obliged to.
Even some exchanges may randomly use this to freeze and block funds from users, claiming these were "flagged" by a cryptic system that inspects the transactions. You are left hostage to their arbitrary decision to let you successfully pass the KYC procedure. If you choose to sidestep their invasive process, they might just hold onto your funds indefinitely.
Your identity has been stolen
KYC data has been found to be for sale on many dark net markets^3. Exchanges may have leaks or hacks, and such leaks contain very sensitive data. We're talking about the full monty: passport or ID scans, proof of address, and even those awkward selfies where you're holding up your ID next to your face. All this data is being left to the mercy of the (mostly) "trust-me-bro" security systems of such companies. Quite scary, isn't it?
As cheap as $10 for 100 documents, with discounts applying for those who buy in bulk, the personal identities of innocent users who passed KYC procedures are for sale. ^3
In short, if you have ever passed the KYC/AML process of a crypto exchange, your privacy is at risk of being compromised, or it might even have already been compromised.
(they) Know Your Coins
You may already know that Bitcoin and most cryptocurrencies have a transparent public blockchain, meaning that all data is shown unencrypted for everyone to see and recorded forever. If you link an address you own to your identity through KYC, for example, by sending an amount from a KYC exchange to it, your Bitcoin is no longer pseudonymous and can then be traced.
If, for instance, you send Bitcoin from such an identified address to another KYC'ed address (say, from a friend), everyone having access to that address-identity link information (exchanges, governments, hackers, etc.) will be able to associate that transaction and know who you are transacting with.
Conclusions
To sum up, KYC does not protect individuals; rather, it's a threat to our privacy, freedom, security and integrity. Sensible information flowing through the internet is thrown into chaos by dubious security measures. It puts borders between many potential customers and businesses, and it helps governments and companies track innocent users. That's the chaos KYC has stirred.
The criminals are using stolen identities from companies that gathered them thanks to these very same regulations that were supposed to combat them. Criminals always know how to circumvent such regulations. In the end, normal people are the most affected by these policies.
The threat that KYC poses to individuals in terms of privacy, security and freedom is not to be neglected. And if we don’t start challenging these systems and questioning their efficacy, we are just one step closer to the dystopian future that is now foreseeable.

@ 39cc53c9:27168656
2025-06-17 16:40:25Over the past few months, I've dedicated my time to a complete rewrite of the kycnot.me website. The technology stack remains unchanged; Golang paired with TailwindCSS. However, I've made some design choices in this iteration that I believe significantly enhance the site. Particularly to backend code.
UI Improvements
You'll notice a refreshed UI that retains the original concept but has some notable enhancements. The service list view is now more visually engaging, it displays additional information in a more aesthetically pleasing manner. Both filtering and searching functionalities have been optimized for speed and user experience.
Service pages have been also redesigned to highlight key information at the top, with the KYC Level box always accessible. The display of service attributes is now more visually intuitive.
The request form, especially the Captcha, has undergone substantial improvements. The new self-made Captcha is robust, addressing the reliability issues encountered with the previous version.
Terms of Service Summarizer
A significant upgrade is the Terms of Service summarizer/reviewer, now powered by AI (GPT-4-turbo). It efficiently condenses each service's ToS, extracting and presenting critical points, including any warnings. Summaries are updated monthly, processing over 40 ToS pages via the OpenAI API using a self-crafted and thoroughly tested prompt.

I've integrated a comment section for each service using Nostr. For guidance on using this feature, visit the dedicated how-to page.
Database
The backend database has transitioned to pocketbase, an open-source Golang backend that has been a pleasure to work with. I maintain an updated fork of the Golang SDK for pocketbase at pluja/pocketbase.
Scoring
The scoring algorithm has also been refined to be more fair. Despite I had considered its removal due to the complexity it adds (it is very difficult to design a fair scoring system), some users highlighted its value, so I kept it. The updated algorithm is available open source.
Listings
Each listing has been re-evaluated, and the ones that were no longer operational were removed. New additions are included, and the backlog of pending services will be addressed progressively, since I still have access to the old database.
API
The API now offers more comprehensive data. For more details, check here.
About Page
The About page has been restructured for brevity and clarity.
Other Changes
Extensive changes have been implemented in the server-side logic, since the whole code base was re-written from the ground up. I may discuss these in a future post, but for now, I consider the current version to be just a bit beyond beta, and additional updates are planned in the coming weeks.

2025-06-17 16:40:24I'm launching a new service review section on this blog in collaboration with OrangeFren. These reviews are sponsored, yet the sponsorship does not influence the outcome of the evaluations. Reviews are done in advance, then, the service provider has the discretion to approve publication without modifications.
Sponsored reviews are independent from the kycnot.me list, being only part of the blog. The reviews have no impact on the scores of the listings or their continued presence on the list. Should any issues arise, I will not hesitate to remove any listing.
The review
WizardSwap is an instant exchange centred around privacy coins. It was launched in 2020 making it old enough to have weathered the 2021 bull run and the subsequent bearish year.
| Pros | Cons | |------|------| | Tor-friendly | Limited liquidity | | Guarantee of no KYC | Overly simplistic design | | Earn by providing liquidity | |
Rating: ★★★★★ Service Website: wizardswap.io
Liquidity
Right off the bat, we'll start off by pointing out that WizardSwap relies on its own liquidity reserves, meaning they aren't just a reseller of Binance or another exchange. They're also committed to a no-KYC policy, when asking them, they even promised they would rather refund a user their original coins, than force them to undergo any sort of verification.
On the one hand, full control over all their infrastructure gives users the most privacy and conviction about the KYC policies remaining in place.
On the other hand, this means the liquidity available for swapping isn't huge. At the time of testing we could only purchase at most about 0.73 BTC with XMR.
It's clear the team behind WizardSwap is aware of this shortfall and so they've come up with a solution unique among instant exchanges. They let you, the user, deposit any of the currencies they support into your account and earn a profit on the trades made using your liquidity.
Trading
Fees on WizardSwap are middle-of-the-pack. The normal fee is 2.2%. That's more than some exchanges that reserve the right to suddenly demand you undergo verification, yet less than half the fees on some other privacy-first exchanges. However as we mentioned in the section above you can earn almost all of that fee (2%) if you provide liquidity to WizardSwap.
It's good that with the current Bitcoin fee market their fees are constant regardless of how much, or how little, you send. This is in stark contrast with some of the alternative swap providers that will charge you a massive premium when attempting to swap small amounts of BTC away.
Test trades
Test trades are always performed without previous notice to the service provider.
During our testing we performed a few test trades and found that every single time WizardSwap immediately detected the incoming transaction and the amount we received was exactly what was quoted before depositing. The fees were inline with what WizardSwap advertises.
- Monero payment proof
- Bitcoin received
- Wizardswap TX link - it's possible that this link may cease to be valid at some point in the future.
ToS and KYC
WizardSwap does not have a Terms of Service or a Privacy Policy page, at least none that can be found by users. Instead, they offer a FAQ section where they addresses some basic questions.
The site does not mention any KYC or AML practices. It also does not specify how refunds are handled in case of failure. However, based on the FAQ section "What if I send funds after the offer expires?" it can be inferred that contacting support is necessary and network fees will be deducted from any refund.
UI & Tor
WizardSwap can be visited both via your usual browser and Tor Browser. Should you decide on the latter you'll find that the website works even with the most strict settings available in the Tor Browser (meaning no JavaScript).
However, when disabling Javascript you'll miss the live support chat, as well as automatic refreshing of the trade page. The lack of the first means that you will have no way to contact support from the trade page if anything goes wrong during your swap, although you can do so by mail.
One important thing to have in mind is that if you were to accidentally close the browser during the swap, and you did not save the swap ID or your browser history is disabled, you'll have no easy way to return to the trade. For this reason we suggest when you begin a trade to copy the url or ID to someplace safe, before sending any coins to WizardSwap.
The UI you'll be greeted by is simple, minimalist, and easy to navigate. It works well not just across browsers, but also across devices. You won't have any issues using this exchange on your phone.
Getting in touch
The team behind WizardSwap appears to be most active on X (formerly Twitter): https://twitter.com/WizardSwap_io
If you have any comments or suggestions about the exchange make sure to reach out to them. In the past they've been very receptive to user feedback, for instance a few months back WizardSwap was planning on removing DeepOnion, but the community behind that project got together ^1 and after reaching out WizardSwap reversed their decision ^2.

2025-06-17 16:40:22Bitcoin enthusiasts frequently and correctly remark how much value it adds to Bitcoin not to have a face, a leader, or a central authority behind it. This particularity means there isn't a single person to exert control over, or a single human point of failure who could become corrupt or harmful to the project.
Because of this, it is said that no other coin can be equally valuable as Bitcoin in terms of decentralization and trustworthiness. Bitcoin is unique not just for being first, but also because of how the events behind its inception developed. This implies that, from Bitcoin onwards, any coin created would have been created by someone, consequently having an authority behind it. For this and some other reasons, some people refer to Bitcoin as "The Immaculate Conception".
While other coins may have their own unique features and advantages, they may not be able to replicate Bitcoin's community-driven nature. However, one other cryptocurrency shares a similar story of mystery behind its creation: Monero.
History of Monero
Bytecoin and CryptoNote
In March 2014, a Bitcointalk thread titled "Bytecoin. Secure, private, untraceable since 2012" was initiated by a user under the nickname "DStrange"^1^. DStrange presented Bytecoin (BCN) as a unique cryptocurrency, in operation since July 2012. Unlike Bitcoin, it employed a new algorithm known as CryptoNote.
DStrange apparently stumbled upon the Bytecoin website by chance while mining a dying bitcoin fork, and decided to create a thread on Bitcointalk^1^. This sparked curiosity among some users, who wondered how could Bytecoin remain unnoticed since its alleged launch in 2012 until then^2^.
Some time after, a user brought up the "CryptoNote v2.0" whitepaper for the first time, underlining its innovative features^4^. Authored by the pseudonymous Nicolas van Saberhagen in October 2013, the CryptoNote v2 whitepaper^5^ highlighted the traceability and privacy problems in Bitcoin. Saberhagen argued that these flaws could not be quickly fixed, suggesting it would be more efficient to start a new project rather than trying to patch the original^5^, an statement simmilar to the one from Satoshi Nakamoto^6^.
Checking with Saberhagen's digital signature, the release date of the whitepaper seemed correct, which would mean that Cryptonote (v1) was created in 2012^7^, although there's an important detail: "Signing time is from the clock on the signer's computer" ^9^.
Moreover, the whitepaper v1 contains a footnote link to a Bitcointalk post dated May 5, 2013^10^, making it impossible for the whitepaper to have been signed and released on December 12, 2012.
As the narrative developed, users discovered that a significant 80% portion of Bytecoin had been pre-mined^11^ and blockchain dates seemed to be faked to make it look like it had been operating since 2012, leading to controversy surrounding the project.
The origins of CryptoNote and Bytecoin remain mysterious, leaving suspicions of a possible scam attempt, although the whitepaper had a good amount of work and thought on it.
The fork
In April 2014, the Bitcointalk user
thankful_for_today
, who had also participated in the Bytecoin thread^12^, announced plans to launch a Bytecoin fork named Bitmonero^13^.The primary motivation behind this fork was "Because there is a number of technical and marketing issues I wanted to do differently. And also because I like ideas and technology and I want it to succeed"^14^. This time Bitmonero did things different from Bytecoin: there was no premine or instamine, and no portion of the block reward went to development.
However, thankful_for_today proposed controversial changes that the community disagreed with. Johnny Mnemonic relates the events surrounding Bitmonero and thankful_for_today in a Bitcointalk comment^15^:
When thankful_for_today launched BitMonero [...] he ignored everything that was discussed and just did what he wanted. The block reward was considerably steeper than what everyone was expecting. He also moved forward with 1-minute block times despite everyone's concerns about the increase of orphan blocks. He also didn't address the tail emission concern that should've (in my opinion) been in the code at launch time. Basically, he messed everything up. Then, he disappeared.
After disappearing for a while, thankful_for_today returned to find that the community had taken over the project. Johnny Mnemonic continues:
I, and others, started working on new forks that were closer to what everyone else was hoping for. [...] it was decided that the BitMonero project should just be taken over. There were like 9 or 10 interested parties at the time if my memory is correct. We voted on IRC to drop the "bit" from BitMonero and move forward with the project. Thankful_for_today suddenly resurfaced, and wasn't happy to learn the community had assumed control of the coin. He attempted to maintain his own fork (still calling it "BitMonero") for a while, but that quickly fell into obscurity.
The unfolding of these events show us the roots of Monero. Much like Satoshi Nakamoto, the creators behind CryptoNote/Bytecoin and thankful_for_today remain a mystery^17^, having disappeared without a trace. This enigma only adds to Monero's value.
Since community took over development, believing in the project's potential and its ability to be guided in a better direction, Monero was given one of Bitcoin's most important qualities: a leaderless nature. With no single face or entity directing its path, Monero is safe from potential corruption or harm from a "central authority".
The community continued developing Monero until today. Since then, Monero has undergone a lot of technological improvements, migrations and achievements such as RingCT and RandomX. It also has developed its own Community Crowdfundinc System, conferences such as MoneroKon and Monerotopia are taking place every year, and has a very active community around it.
Monero continues to develop with goals of privacy and security first, ease of use and efficiency second. ^16^
This stands as a testament to the power of a dedicated community operating without a central figure of authority. This decentralized approach aligns with the original ethos of cryptocurrency, making Monero a prime example of community-driven innovation. For this, I thank all the people involved in Monero, that lead it to where it is today.
If you find any information that seems incorrect, unclear or any missing important events, please contact me and I will make the necessary changes.

2025-06-15 14:13:52“The future is there... staring back at us. Trying to make sense of the fiction we will have become.” — William Gibson.
This month is the 4th anniversary of kycnot.me. Thank you for being here.
Fifteen years ago, Satoshi Nakamoto introduced Bitcoin, a peer-to-peer electronic cash system: a decentralized currency free from government and institutional control. Nakamoto's whitepaper showed a vision for a financial system based on trustless transactions, secured by cryptography. Some time forward and KYC (Know Your Customer), AML (Anti-Money Laundering), and CTF (Counter-Terrorism Financing) regulations started to come into play.
What a paradox: to engage with a system designed for decentralization, privacy, and independence, we are forced to give away our personal details. Using Bitcoin in the economy requires revealing your identity, not just to the party you interact with, but also to third parties who must track and report the interaction. You are forced to give sensitive data to entities you don't, can't, and shouldn't trust. Information can never be kept 100% safe; there's always a risk. Information is power, who knows about you has control over you.
Information asymmetry creates imbalances of power. When entities have detailed knowledge about individuals, they can manipulate, influence, or exploit this information to their advantage. The accumulation of personal data by corporations and governments enables extensive surveillances.
Such practices, moreover, exclude individuals from traditional economic systems if their documentation doesn't meet arbitrary standards, reinforcing a dystopian divide. Small businesses are similarly burdened by the costs of implementing these regulations, hindering free market competition^1:
How will they keep this information safe? Why do they need my identity? Why do they force businesses to enforce such regulations? It's always for your safety, to protect you from the "bad". Your life is perpetually in danger: terrorists, money launderers, villains... so the government steps in to save us.
‟Hush now, baby, baby, don't you cry Mamma's gonna make all of your nightmares come true Mamma's gonna put all of her fears into you Mamma's gonna keep you right here, under her wing She won't let you fly, but she might let you sing Mamma's gonna keep baby cosy and warm” — Mother, Pink Floyd
We must resist any attack on our privacy and freedom. To do this, we must collaborate.
If you have a service, refuse to ask for KYC; find a way. Accept cryptocurrencies like Bitcoin and Monero. Commit to circular economies. Remove the need to go through the FIAT system. People need fiat money to use most services, but we can change that.
If you're a user, donate to and prefer using services that accept such currencies. Encourage your friends to accept cryptocurrencies as well. Boycott FIAT system to the greatest extent you possibly can.
This may sound utopian, but it can be achieved. This movement can't be stopped. Go kick the hornet's nest.
“We must defend our own privacy if we expect to have any. We must come together and create systems which allow anonymous transactions to take place. People have been defending their own privacy for centuries with whispers, darkness, envelopes, closed doors, secret handshakes, and couriers. The technologies of the past did not allow for strong privacy, but electronic technologies do.” — Eric Hughes, A Cypherpunk's Manifesto
The anniversary
Four years ago, I began exploring ways to use crypto without KYC. I bookmarked a few favorite services and thought sharing them to the world might be useful. That was the first version of kycnot.me — a simple list of about 15 services. Since then, I've added services, rewritten it three times, and improved it to what it is now.
kycnot.me has remained 100% independent and 100% open source^2 all these years. I've received offers to buy the site, all of which I have declined and will continue to decline. It has been DDoS attacked many times, but we made it through. I have also rewritten the whole site almost once per year (three times in four years).
The code and scoring algorithm are open source (contributions are welcome) and I can't arbitrarly change a service's score without adding or removing attributes, making any arbitrary alterations obvious if they were fake. You can even see the score summary for any service's score.
I'm a one-person team, dedicating my free time to this project. I hope to keep doing so for many more years. Again, thank you for being part of this.

2025-06-17 18:02:14A história do Bitcoin é pontuada por marcos simbólicos que representam não apenas a evolução técnica da moeda digital, mas também sua trajetória rumo à legitimidade econômica e política. Neste artigo, revisitamos alguns dos momentos mais emblemáticos que marcaram a adoção do Bitcoin, desde seu uso inicial em uma simples transação até o seu reconhecimento como moeda oficial por nações soberanas.
A pizza mais cara da história
Em 22 de maio de 2010, Laszlo Hanyecz fez história ao pagar 10.000 BTC por duas pizzas. Na época, essa quantia equivalia a cerca de 40 dólares. Hoje, essas mesmas moedas valeriam centenas de milhões de dólares, tornando essa a refeição mais cara já registrada. Mais do que uma curiosidade, essa transação marcou a primeira vez em que o Bitcoin foi usado em uma troca comercial real, comprovando seu potencial como meio de pagamento.
Silk Road e o lado obscuro da adoção inicial
Ainda que controverso, o uso do Bitcoin no marketplace Silk Road mostrou ao mundo que a moeda digital era funcional como meio de troca em larga escala. A plataforma operou entre 2011 e 2013 e foi um catalisador para o desenvolvimento de infraestrutura em torno do BTC, apesar dos impactos negativos na imagem da criptomoeda.
Mt. Gox e a primeira grande crise
Em 2014, a corretora Mt. Gox, responsável por cerca de 70% das transações de Bitcoin no mundo, declarou falência após perder cerca de 850 mil BTC. O escândalo abalou a confiança no ecossistema, mas também deu início a um movimento de amadurecimento: a busca por melhores práticas de segurança, regulação e profissionalização do setor.
El Salvador e o reconhecimento oficial
Em setembro de 2021, El Salvador tornou-se o primeiro país a reconhecer o Bitcoin como moeda de curso legal. A medida, defendida pelo presidente Nayib Bukele, foi recebida com entusiasmo por entusiastas e com ceticismo por instituições financeiras internacionais. O experimento salvadorenho colocou o Bitcoin no centro do debate geopolítico e abriu precedentes para outras nações considerarem o mesmo caminho.
Resumindo, cada um desses momentos representa uma etapa distinta na evolução do Bitcoin: da experimentação à adoção institucional. Ao revisitarmos esses casos emblemáticos, conseguimos entender não apenas como o Bitcoin evoluiu tecnicamente, mas também como sua narrativa se consolidou como parte da história financeira contemporânea. Se a compra da pizza simbolizou o nascimento prático do BTC, o reconhecimento oficial por nações inteiras sugere um futuro em que a moeda digital pode ser protagonista em novas formas de organização econômica global.
Muito obrigado por teres lido o texto até aqui, espero que esteja tudo bem contigo e um abraço enorme do teu madeirense bitcoiner maximalista favorito. Viva a liberdade!

2025-06-17 16:40:21I've been thinking about how to improve my seed backup in a cheap and cool way, mostly for fun. Until now, I had the seed written on a piece of paper in a desk drawer, and I wanted something more durable and fire-proof.
After searching online, I found two options I liked the most: the Cryptosteel Capsule and the Trezor Keep. These products are nice but quite expensive, and I didn't want to spend that much on my seed backup. Privacy is also important, and sharing details like a shipping address makes me uncomfortable. This concern has grown since the Ledger incident^1. A $5 wrench attack^2 seems too cheap, even if you only hold a few sats.
Upon seeing the design of Cryptosteel, I considered creating something similar at home. Although it may not be as cool as their device, it could offer almost the same in terms of robustness and durability.
Step 1: Get the materials and tools
When choosing the materials, you will want to go with stainless steel. It is durable, resistant to fire, water, and corrosion, very robust, and does not rust. Also, its price point is just right; it's not the cheapest, but it's cheap for the value you get.
I went to a material store and bought:
- Two bolts
- Two hex nuts and head nuts for the bolts
- A bag of 30 washers
All items were made of stainless steel. The total price was around €6. This is enough for making two seed backups.
You will also need:
- A set of metal letter stamps (I bought a 2mm-size letter kit since my washers were small, 6mm in diameter)
- You can find these in local stores or online marketplaces. The set I bought cost me €13.
- A good hammer
- A solid surface to stamp on
Total spent: 19€ for two backups
Step 2: Stamp and store
Once you have all the materials, you can start stamping your words. There are many videos on the internet that use fancy 3D-printed tools to get the letters nicely aligned, but I went with the free-hand option. The results were pretty decent.
I only stamped the first 4 letters for each word since the BIP-39 wordlist allows for this. Because my stamping kit did not include numbers, I used alphabet letters to define the order. This way, if all the washers were to fall off, I could still reassemble the seed correctly.
The final result
So this is the final result. I added two smaller washers as protection and also put the top washer reversed so the letters are not visible:
Compared to the Cryptosteel or the Trezor Keep, its size is much more compact. This makes for an easier-to-hide backup, in case you ever need to hide it inside your human body.
Some ideas
Tamper-evident seal
To enhance the security this backup, you can consider using a tamper-evident seal. This can be easily achieved by printing a unique image or using a specific day's newspaper page (just note somewhere what day it was).
Apply a thin layer of glue to the washer's surface and place the seal over it. If someone attempts to access the seed, they will be forced to destroy the seal, which will serve as an evident sign of tampering.
This simple measure will provide an additional layer of protection and allow you to quickly identify any unauthorized access attempts.
Note that this method is not resistant to outright theft. The tamper-evident seal won't stop a determined thief but it will prevent them from accessing your seed without leaving any trace.
Redundancy
Make sure to add redundancy. Make several copies of this cheap backup, and store them in separate locations.
Unique wordset
Another layer of security could be to implement your own custom mnemonic dictionary. However, this approach has the risk of permanently losing access to your funds if not implemented correctly.
If done properly, you could potentially end up with a highly secure backup, as no one else would be able to derive the seed phrase from it. To create your custom dictionary, assign a unique number from 1 to 2048 to a word of your choice. Maybe you could use a book, and index the first 2048 unique words that appear. Make sure to store this book and even get a couple copies of it (digitally and phisically).
This self-curated set of words will serve as your personal BIP-39 dictionary. When you need to translate between your custom dictionary and the official BIP-39 wordlist, simply use the index number to find the corresponding word in either list.
Never write the idex or words on your computer (Do not use

2025-06-17 16:40:19kycnot.me features a somewhat hidden tool that some users may not be aware of. Every month, an automated job crawls every listed service's Terms of Service (ToS) and FAQ pages and conducts an AI-driven analysis, generating a comprehensive overview that highlights key points related to KYC and user privacy.
Here's an example: Changenow's Tos Review
Why?
ToS pages typically contain a lot of complicated text. Since the first versions of kycnot.me, I have tried to provide users a comprehensive overview of what can be found in such documents. This automated method keeps the information up-to-date every month, which was one of the main challenges with manual updates.
A significant part of the time I invest in investigating a service for kycnot.me involves reading the ToS and looking for any clauses that might indicate aggressive KYC practices or privacy concerns. For the past four years, I performed this task manually. However, with advancements in language models, this process can now be somewhat automated. I still manually review the ToS for a quick check and regularly verify the AI’s findings. However, over the past three months, this automated method has proven to be quite reliable.
Having a quick ToS overview section allows users to avoid reading the entire ToS page. Instead, you can quickly read the important points that are grouped, summarized, and referenced, making it easier and faster to understand the key information.
Limitations
This method has a key limitation: JS-generated pages. For this reason, I was using Playwright in my crawler implementation. I plan to make a release addressing this issue in the future. There are also sites that don't have ToS/FAQ pages, but these sites already include a warning in that section.
Another issue is false positives. Although not very common, sometimes the AI might incorrectly interpret something harmless as harmful. Such errors become apparent upon reading; it's clear when something marked as bad should not be categorized as such. I manually review these cases regularly, checking for anything that seems off and then removing any inaccuracies.
Overall, the automation provides great results.
How?
There have been several iterations of this tool. Initially, I started with GPT-3.5, but the results were not good in any way. It made up many things, and important thigs were lost on large ToS pages. I then switched to GPT-4 Turbo, but it was expensive. Eventually, I settled on Claude 3 Sonnet, which provides a quality compromise between GPT-3.5 and GPT-4 Turbo at a more reasonable price, while allowing a generous 200K token context window.
I designed a prompt, which is open source^1, that has been tweaked many times and will surely be adjusted further in the future.
For the ToS scraping part, I initially wrote a scraper API using Playwright^2, but I replaced it with Jina AI Reader^3, which works quite well and is designed for this task.
Non-conflictive ToS
All services have a dropdown in the ToS section called "Non-conflictive ToS Reviews." These are the reviews that the AI flagged as not needing a user warning. I still provide these because I think they may be interesting to read.
Feedback and contributing
You can give me feedback on this tool, or share any inaccuraties by either opening an issue on Codeberg^4 or by contacting me ^5.
You can contribute with pull requests, which are always welcome, or you can support this project with any of the listed ways.

@ 39cc53c9:27168656
2025-06-15 14:04:11The new website is finally live! I put in a lot of hard work over the past months on it. I'm proud to say that it's out now and it looks pretty cool, at least to me!
Why rewrite it all?
The old kycnot.me site was built using Python with Flask about two years ago. Since then, I've gained a lot more experience with Golang and coding in general. Trying to update that old codebase, which had a lot of design flaws, would have been a bad idea. It would have been like building on an unstable foundation.
That's why I made the decision to rewrite the entire application. Initially, I chose to use SvelteKit with JavaScript. I did manage to create a stable site that looked similar to the new one, but it required Jav aScript to work. As I kept coding, I started feeling like I was repeating "the Python mistake". I was writing the app in a language I wasn't very familiar with (just like when I was learning Python at that mom ent), and I wasn't happy with the code. It felt like spaghetti code all the time.
So, I made a complete U-turn and started over, this time using Golang. While I'm not as proficient in Golang as I am in Python now, I find it to be a very enjoyable language to code with. Most aof my recent pr ojects have been written in Golang, and I'm getting the hang of it. I tried to make the best decisions I could and structure the code as well as possible. Of course, there's still room for improvement, which I'll address in future updates.
Now I have a more maintainable website that can scale much better. It uses a real database instead of a JSON file like the old site, and I can add many more features. Since I chose to go with Golang, I mad e the "tradeoff" of not using JavaScript at all, so all the rendering load falls on the server. But I believe it's a tradeoff that's worth it.
What's new
- UI/UX - I've designed a new logo and color palette for kycnot.me. I think it looks pretty cool and cypherpunk. I am not a graphic designer, but I think I did a decent work and I put a lot of thinking on it to make it pleasant!
- Point system - The new point system provides more detailed information about the listings, and can be expanded to cover additional features across all services. Anyone can request a new point!
- ToS Scrapper: I've implemented a powerful automated terms-of-service scrapper that collects all the ToS pages from the listings. It saves you from the hassle of reading the ToS by listing the lines that are suspiciously related to KYC/AML practices. This is still in development and it will improve for sure, but it works pretty fine right now!
- Search bar - The new search bar allows you to easily filter services. It performs a full-text search on the Title, Description, Category, and Tags of all the services. Looking for VPN services? Just search for "vpn"!
- Transparency - To be more transparent, all discussions about services now take place publicly on GitLab. I won't be answering any e-mails (an auto-reply will prompt to write to the corresponding Gitlab issue). This ensures that all service-related matters are publicly accessible and recorded. Additionally, there's a real-time audits page that displays database changes.
- Listing Requests - I have upgraded the request system. The new form allows you to directly request services or points without any extra steps. In the future, I plan to enable requests for specific changes to parts of the website.
- Lightweight and fast - The new site is lighter and faster than its predecessor!
- Tor and I2P - At last! kycnot.me is now officially on Tor and I2P!
How?
This rewrite has been a labor of love, in the end, I've been working on this for more than 3 months now. I don't have a team, so I work by myself on my free time, but I find great joy in helping people on their private journey with cryptocurrencies. Making it easier for individuals to use cryptocurrencies without KYC is a goal I am proud of!
If you appreciate my work, you can support me through the methods listed here. Alternatively, feel free to send me an email with a kind message!
Technical details
All the code is written in Golang, the website makes use of the chi router for the routing part. I also make use of BigCache for caching database requests. There is 0 JavaScript, so all the rendering load falls on the server, this means it needed to be efficient enough to not drawn with a few users since the old site was reporting about 2M requests per month on average (note that this are not unique users).
The database is running with mariadb, using gorm as the ORM. This is more than enough for this project. I started working with an
sqlite
database, but I ended up migrating to mariadb since it works better with JSON.The scraper is using chromedp combined with a series of keywords, regex and other logic. It runs every 24h and scraps all the services. You can find the scraper code here.
The frontend is written using Golang Templates for the HTML, and TailwindCSS plus DaisyUI for the CSS classes framework. I also use some plain CSS, but it's minimal.
The requests forms is the only part of the project that requires JavaScript to be enabled. It is needed for parsing some from fields that are a bit complex and for the "captcha", which is a simple Proof of Work that runs on your browser, destinated to avoid spam. For this, I use mCaptcha.

The review
Swapter.io is an all-purpose instant exchange. They entered the scene in the depths of the bear market about 2 years ago in June of 2022.
| Pros | Cons | | --------------- | ---------------------------------- | | Low fees | Shotgun KYC with opaque triggers | | Large liquidity | Relies on 3rd party liquidity | | Works over Tor | Front-end not synced with back-end | | Pretty UI | |
Rating: ★★★☆☆ Service Website: swapter.io
⚠️ There is an ongoing issue with this service: read more on Reddit.
Test Trades
During our testing we performed a trade from XMR to LTC, and then back to XMR.
Our first trade had the ID of:
mpUitpGemhN8jjNAjQuo6EvQ
. We were promised 0.8 LTC for sending 0.5 XMR, before we sent the Monero. When the Monero arrived we were sent 0.799 LTC.On the return journey we performed trade with ID:
yaCRb5pYcRKAZcBqg0AzEGYg
. This time we were promised 0.4815 XMR for sending 0.799 LTC. After Litecoin arrived we were sent 0.4765 XMR.As such we saw a discrepancy of
~0.1%
in the first trade and~1%
in the second trade. Considering those trades were floating we determine the estimates presented in the UI to be highly accurate and honest.Of course Swapter could've been imposing a large fee on their estimates, but we checked their estimates against CoinGecko and found the difference to be equivalent to a fee of just over
0.5%
. Perfectly in line with other swapping services.Trading
Swapter supports BTC, LTC, XMR and well over a thousand other coins. Sadly they don't support the Lightning Network. For the myriad of currencies they deal with they provide massive upper limits. You could exchange tens, or even hundreds, of thousands of dollars worth of cryptocurrency in a single trade (although we wouldn't recommend it).
The flip side to this is that Swapter relies on 3rd party liquidity. Aside from the large liqudity this also benefits the user insofar as it allows for very low fees. However, it also comes with a negative - the 3rd party gets to see all your trades. Unfortunately Swapter opted not to share where they source their liquidity in their Privacy Policy or Terms of Service.
KYC & AML policies
Swapter reserves the right to require its users to provide their full name, their date of birth, their address and government-issued ID. A practice known as "shotgun KYC". This should not happen often - in our testing it never did - however it's not clear when exactly it could happen. The AML & KYC policy provided on Swapter's website simply states they will put your trade on hold if their "risk scoring system [deems it] as suspicious".
Worse yet, if they determine that "any of the information [the] customer provided is incorrect, false, outdated, or incomplete" then Swapter may decide to terminate all of the services they provide to the user. What exactly would happen to their funds in such a case remains unclear.
The only clarity we get is that the Swapter policy outlines a designated 3rd party that will verify the information provided by the user. The third party's name is Sum & Substance Ltd, also simply known as samsub and available at sumsub.com
It's understandable that some exchanges will decide on a policy of this sort, especially when they rely on external liquidity, but we would prefer more clarity be given. When exactly is a trade suspicious?
Tor
We were pleased to discover Swapter works over Tor. However, they do not provide a Tor mirror, nor do they work without JavaScript. Additionally, we found that some small features, such as the live chat, did not work over Tor. Fortunately, other means of contacting their support are still available.
UI
We have found the Swapter UI to be very modern, straightforward and simple to use. It's available in 4 languages (English, French, Dutch and Russian), although we're unable to vouch for the quality of some of those, the ones that we used seemed perfectly serviceable.
Our only issue with the UI was that it claims the funds have been sent following the trade, when in reality it seems to take the backend a minute or so to actually broadcast the transaction.
Getting in touch
Swapter's team has a chat on their website, a support email address and a support Telegram. Their social media presence in most active on Telegram and X (formerly Twitter).

2025-06-17 16:40:16“The future is there... staring back at us. Trying to make sense of the fiction we will have become.” — William Gibson.
This month is the 4th anniversary of kycnot.me. Thank you for being here.
Fifteen years ago, Satoshi Nakamoto introduced Bitcoin, a peer-to-peer electronic cash system: a decentralized currency free from government and institutional control. Nakamoto's whitepaper showed a vision for a financial system based on trustless transactions, secured by cryptography. Some time forward and KYC (Know Your Customer), AML (Anti-Money Laundering), and CTF (Counter-Terrorism Financing) regulations started to come into play.
What a paradox: to engage with a system designed for decentralization, privacy, and independence, we are forced to give away our personal details. Using Bitcoin in the economy requires revealing your identity, not just to the party you interact with, but also to third parties who must track and report the interaction. You are forced to give sensitive data to entities you don't, can't, and shouldn't trust. Information can never be kept 100% safe; there's always a risk. Information is power, who knows about you has control over you.
Information asymmetry creates imbalances of power. When entities have detailed knowledge about individuals, they can manipulate, influence, or exploit this information to their advantage. The accumulation of personal data by corporations and governments enables extensive surveillances.
Such practices, moreover, exclude individuals from traditional economic systems if their documentation doesn't meet arbitrary standards, reinforcing a dystopian divide. Small businesses are similarly burdened by the costs of implementing these regulations, hindering free market competition^1:
How will they keep this information safe? Why do they need my identity? Why do they force businesses to enforce such regulations? It's always for your safety, to protect you from the "bad". Your life is perpetually in danger: terrorists, money launderers, villains... so the government steps in to save us.
‟Hush now, baby, baby, don't you cry Mamma's gonna make all of your nightmares come true Mamma's gonna put all of her fears into you Mamma's gonna keep you right here, under her wing She won't let you fly, but she might let you sing Mamma's gonna keep baby cosy and warm” — Mother, Pink Floyd
We must resist any attack on our privacy and freedom. To do this, we must collaborate.
If you have a service, refuse to ask for KYC; find a way. Accept cryptocurrencies like Bitcoin and Monero. Commit to circular economies. Remove the need to go through the FIAT system. People need fiat money to use most services, but we can change that.
If you're a user, donate to and prefer using services that accept such currencies. Encourage your friends to accept cryptocurrencies as well. Boycott FIAT system to the greatest extent you possibly can.
This may sound utopian, but it can be achieved. This movement can't be stopped. Go kick the hornet's nest.
“We must defend our own privacy if we expect to have any. We must come together and create systems which allow anonymous transactions to take place. People have been defending their own privacy for centuries with whispers, darkness, envelopes, closed doors, secret handshakes, and couriers. The technologies of the past did not allow for strong privacy, but electronic technologies do.” — Eric Hughes, A Cypherpunk's Manifesto
The anniversary
Four years ago, I began exploring ways to use crypto without KYC. I bookmarked a few favorite services and thought sharing them to the world might be useful. That was the first version of kycnot.me — a simple list of about 15 services. Since then, I've added services, rewritten it three times, and improved it to what it is now.
kycnot.me has remained 100% independent and 100% open source^2 all these years. I've received offers to buy the site, all of which I have declined and will continue to decline. It has been DDoS attacked many times, but we made it through. I have also rewritten the whole site almost once per year (three times in four years).
The code and scoring algorithm are open source (contributions are welcome) and I can't arbitrarly change a service's score without adding or removing attributes, making any arbitrary alterations obvious if they were fake. You can even see the score summary for any service's score.
I'm a one-person team, dedicating my free time to this project. I hope to keep doing so for many more years. Again, thank you for being part of this.

2025-06-17 16:40:15Silent.link is an anonymous eSIM provider. They offer pay-as-you-go roaming in 160+ countries.
Pros
- Anonymous
- Private payment options
- High performance
- Global availability
Cons
- Need to select the right networks sometimes
- Latency
- Data and incoming SMS & call only
Rating
★★★★★
Service website
eSIMs replace traditional, physical SIM cards, if you have a fairly new phone, odds are it supports them. Since most people change their mobile carrier very rarely, the most common use case for these new eSIMs is their use in travel. Although their use as a piece of a larger OPSEC puzzle to improve privacy when using the internet from your phone is increasingly popular too.
Silent.link is not the only eSIM provider out there. Yet, they’re so unique that even Twitter’s (now X) founder Jack Dorsey recommends them.
Let’s start off with a quick explanation of how Silent.link works and what pay-as-you-go means. Most other eSIM providers will sell you packages of GBs with an expiration date. For instance imagine you’re visiting France then going to the UK after a few months. With other providers you might buy a 10GB in France package valid for 7 days, then after some months a 10GB in the UK package also valid for 7 days. You likely won’t use up the full package in either country and the remaining capacity will be voided as the package expires.
Silent.link’s pay-as-you-go is different. There are no geographic packages. There are no expiration dates. You simply have a balance denominated in USD and are charged as you use up the data according to the pricing of whichever local carrier you’re connecting via.
Preparing for the same trips from the example above you’d simply top-up your Silent.link balance with $10. Then you’d use Silent.link in France paying $1.33/GB, you’d only be charged for the exact amount used, then you’d go to the UK and pay $1.54/GB from the balance you had left over from France. It doesn’t matter how much time passes between the trips, because Silent.link balances don’t expire. If you have a balance left over you can use it on a future trip, or simply use it up in your home country.
Pros
Anonymity
Silent.link is anonymous. Most other eSIM providers require some form of identification. This can be a traditional, full KYC, procedure involving your ID or passport numbers or, as seemingly innocent, as verifying your phone number with your main carrier. Regardless, a link between the eSIM you bought online and your identity is established.
In some countries you’ll be able to pick up a traditional SIM (or the new eSIM) from a local carrier without undergoing this verification. This can still be a hassle though. You’ll need to look up the laws before travelling, you’ll need to find a local store selling them, you’ll need to decide how you’ll pay privately, etc. And that’s the best case, that’s assuming the country you want to get the SIM in allows you to buy one anonymously.
Private payment methods
Silent.link only accepts cryptocurrency and according to their stats, most payments are made with Bitcoin (either onchain or using the Lightning Network) or with Monero. As such paying anonymously is not a problem. The use a self-hosted instance of BTCPay Server to process payments and operate their own LN node. The entire checkout process can be completed over Tor.
Cons
Network selection
Although you can skip the hassle of buying a new eSIM every time you travel it’s a good idea to look up the pricing of different mobile networks in the country you’re going to. The differences can be trivial, but can also be 100x. If a specific mobile network offers a much better deal, you’ll probably want to dive into your phone’s settings to make sure it only connects to that network.
High prices for some regions
Second issue can be that, especially for poorer countries, Silent.link might not have the best prices. For instance if you travel to Angola you’ll end up paying $155.44/GB. But if you search around for other providers you’ll find eSIM that offer much lower prices for that same country.
Data & incoming SMS & calls only
These eSIMs are either data-only or only offer data and inbound sms and calls. You can’t use Silent.link eSIMs to send texts or make phone calls.
Latency
For most use-cases this shouldn’t matter, but the way roaming works is that when you’re abroad your data is first sent to your home country then sent out into the internet from there. For instance if you’re a Brit on holiday in Spain wherever you open up a website your phone communicates with the Spanish network who forwards the request to your home network in the UK and only there does the request start going towards the website you’re trying to load. The response takes the same path in reverse.
The home network for the Silent.link eSIMs is Poland. To take an extreme (antipodal) example, if you’re in Chile loading a Chilean website your request will go to Poland then back from Poland to the website’s server in Chile, then the response will go from Chile to Poland to you (in Chile). All those trips add latency. In our testing, done during the recent OrangeFren.com meetup in Istanbul, the difference was an additional 73ms. The bandwidth, however, was exceptional, easily surpassing 100 Mbps.
This latency issue isn’t unique to Silent.link, other eSIM providers usually suffer from it too, though their home network may be better suited for your latency needs. If you need the best latency we recommend a SIM from a local provider (or WiFi).
This proxy behaviour isn’t all negative however. It may potentially allow you to circumvent censorship or geoblocking if you’re trying to access resources available from Poland, but unavailable elsewhere.
Besides Istanbul one of the countries we also tested Silent.link in was Northern Cyprus. This territory is mostly unrecognized. It’s a country that, depending on who you ask, is or isn’t real. Despite this unresolved geopolitical status Silent.link performed without any issues.
Installation
If you decide to give Silent.link a try, you'll need to select if you want a data-only plan or a plan with inbound SMS & calling, once you complete the payment simply scan the QR code on the order confirmation page with your phone. Make sure to save the url of that order confirmation page somewhere! You will need it to top up your eSIM and check your remaining balance.
Getting in touch
The preferred way of contacting Silent.link's support is using the website's built-in chat function. Alternative methods include X (formerly Twitter), Matrix and email.
Their support is online from 09:00 - 21:00 UTC although even when testing outside of those hours we got a reply within a minute.

2025-06-15 14:04:08Over the past few months, I've dedicated my time to a complete rewrite of the kycnot.me website. The technology stack remains unchanged; Golang paired with TailwindCSS. However, I've made some design choices in this iteration that I believe significantly enhance the site. Particularly to backend code.
UI Improvements
You'll notice a refreshed UI that retains the original concept but has some notable enhancements. The service list view is now more visually engaging, it displays additional information in a more aesthetically pleasing manner. Both filtering and searching functionalities have been optimized for speed and user experience.
Service pages have been also redesigned to highlight key information at the top, with the KYC Level box always accessible. The display of service attributes is now more visually intuitive.
The request form, especially the Captcha, has undergone substantial improvements. The new self-made Captcha is robust, addressing the reliability issues encountered with the previous version.
Terms of Service Summarizer
A significant upgrade is the Terms of Service summarizer/reviewer, now powered by AI (GPT-4-turbo). It efficiently condenses each service's ToS, extracting and presenting critical points, including any warnings. Summaries are updated monthly, processing over 40 ToS pages via the OpenAI API using a self-crafted and thoroughly tested prompt.
Nostr Comments
I've integrated a comment section for each service using Nostr. For guidance on using this feature, visit the dedicated how-to page.
Database
The backend database has transitioned to pocketbase, an open-source Golang backend that has been a pleasure to work with. I maintain an updated fork of the Golang SDK for pocketbase at pluja/pocketbase.
Scoring
The scoring algorithm has also been refined to be more fair. Despite I had considered its removal due to the complexity it adds (it is very difficult to design a fair scoring system), some users highlighted its value, so I kept it. The updated algorithm is available open source.
Listings
Each listing has been re-evaluated, and the ones that were no longer operational were removed. New additions are included, and the backlog of pending services will be addressed progressively, since I still have access to the old database.
API
The API now offers more comprehensive data. For more details, check here.
About Page
The About page has been restructured for brevity and clarity.
Other Changes
Extensive changes have been implemented in the server-side logic, since the whole code base was re-written from the ground up. I may discuss these in a future post, but for now, I consider the current version to be just a bit beyond beta, and additional updates are planned in the coming weeks.

2025-06-15 11:51:25Bitcoin enthusiasts frequently and correctly remark how much value it adds to Bitcoin not to have a face, a leader, or a central authority behind it. This particularity means there isn't a single person to exert control over, or a single human point of failure who could become corrupt or harmful to the project.
Because of this, it is said that no other coin can be equally valuable as Bitcoin in terms of decentralization and trustworthiness. Bitcoin is unique not just for being first, but also because of how the events behind its inception developed. This implies that, from Bitcoin onwards, any coin created would have been created by someone, consequently having an authority behind it. For this and some other reasons, some people refer to Bitcoin as "The Immaculate Conception".
While other coins may have their own unique features and advantages, they may not be able to replicate Bitcoin's community-driven nature. However, one other cryptocurrency shares a similar story of mystery behind its creation: Monero.
History of Monero
Bytecoin and CryptoNote
In March 2014, a Bitcointalk thread titled "Bytecoin. Secure, private, untraceable since 2012" was initiated by a user under the nickname "DStrange"^1^. DStrange presented Bytecoin (BCN) as a unique cryptocurrency, in operation since July 2012. Unlike Bitcoin, it employed a new algorithm known as CryptoNote.
DStrange apparently stumbled upon the Bytecoin website by chance while mining a dying bitcoin fork, and decided to create a thread on Bitcointalk^1^. This sparked curiosity among some users, who wondered how could Bytecoin remain unnoticed since its alleged launch in 2012 until then^2^.
Some time after, a user brought up the "CryptoNote v2.0" whitepaper for the first time, underlining its innovative features^4^. Authored by the pseudonymous Nicolas van Saberhagen in October 2013, the CryptoNote v2 whitepaper^5^ highlighted the traceability and privacy problems in Bitcoin. Saberhagen argued that these flaws could not be quickly fixed, suggesting it would be more efficient to start a new project rather than trying to patch the original^5^, an statement simmilar to the one from Satoshi Nakamoto^6^.
Checking with Saberhagen's digital signature, the release date of the whitepaper seemed correct, which would mean that Cryptonote (v1) was created in 2012^7^, although there's an important detail: "Signing time is from the clock on the signer's computer" ^9^.
Moreover, the whitepaper v1 contains a footnote link to a Bitcointalk post dated May 5, 2013^10^, making it impossible for the whitepaper to have been signed and released on December 12, 2012.
As the narrative developed, users discovered that a significant 80% portion of Bytecoin had been pre-mined^11^ and blockchain dates seemed to be faked to make it look like it had been operating since 2012, leading to controversy surrounding the project.
The origins of CryptoNote and Bytecoin remain mysterious, leaving suspicions of a possible scam attempt, although the whitepaper had a good amount of work and thought on it.
The fork
In April 2014, the Bitcointalk user
thankful_for_today
, who had also participated in the Bytecoin thread^12^, announced plans to launch a Bytecoin fork named Bitmonero^13^.The primary motivation behind this fork was "Because there is a number of technical and marketing issues I wanted to do differently. And also because I like ideas and technology and I want it to succeed"^14^. This time Bitmonero did things different from Bytecoin: there was no premine or instamine, and no portion of the block reward went to development.
However, thankful_for_today proposed controversial changes that the community disagreed with. Johnny Mnemonic relates the events surrounding Bitmonero and thankful_for_today in a Bitcointalk comment^15^:
When thankful_for_today launched BitMonero [...] he ignored everything that was discussed and just did what he wanted. The block reward was considerably steeper than what everyone was expecting. He also moved forward with 1-minute block times despite everyone's concerns about the increase of orphan blocks. He also didn't address the tail emission concern that should've (in my opinion) been in the code at launch time. Basically, he messed everything up. Then, he disappeared.
After disappearing for a while, thankful_for_today returned to find that the community had taken over the project. Johnny Mnemonic continues:
I, and others, started working on new forks that were closer to what everyone else was hoping for. [...] it was decided that the BitMonero project should just be taken over. There were like 9 or 10 interested parties at the time if my memory is correct. We voted on IRC to drop the "bit" from BitMonero and move forward with the project. Thankful_for_today suddenly resurfaced, and wasn't happy to learn the community had assumed control of the coin. He attempted to maintain his own fork (still calling it "BitMonero") for a while, but that quickly fell into obscurity.
The unfolding of these events show us the roots of Monero. Much like Satoshi Nakamoto, the creators behind CryptoNote/Bytecoin and thankful_for_today remain a mystery^17^, having disappeared without a trace. This enigma only adds to Monero's value.
Since community took over development, believing in the project's potential and its ability to be guided in a better direction, Monero was given one of Bitcoin's most important qualities: a leaderless nature. With no single face or entity directing its path, Monero is safe from potential corruption or harm from a "central authority".
The community continued developing Monero until today. Since then, Monero has undergone a lot of technological improvements, migrations and achievements such as RingCT and RandomX. It also has developed its own Community Crowdfundinc System, conferences such as MoneroKon and Monerotopia are taking place every year, and has a very active community around it.
Monero continues to develop with goals of privacy and security first, ease of use and efficiency second. ^16^
This stands as a testament to the power of a dedicated community operating without a central figure of authority. This decentralized approach aligns with the original ethos of cryptocurrency, making Monero a prime example of community-driven innovation. For this, I thank all the people involved in Monero, that lead it to where it is today.
If you find any information that seems incorrect, unclear or any missing important events, please contact me and I will make the necessary changes.

@ 39cc53c9:27168656
2025-06-17 16:40:13After almost 3 months of work, we've completed the redesign of kycnot.me. More modern and with many new features.
Privacy remains the foundation - everything still works with JavaScript disabled. If you enable JS, you will get some nice-to-have features like lazy loading and smoother page transitions, but nothing essential requires it.
User Accounts
We've introduced user accounts that require zero personal information:
- Secret user tokens - no email, no phone number, no personal data
- Randomly generated usernames for default privacy and fairness
- Karma system that rewards contributions and unlocks features: custom display names, profile pictures, and more.
Reviews and Community Discussions
On the previous sites, I was using third party open source tools for the comments and discussions. This time, I've built my own from scratch, fully integrated into the site, without JavaScript requirements.
Everyone can share their experiences and help others make informed decisions:
- Ratings: Comments can have a 1-5 star rating attached. You can have one rating per service and it will affect the overall user score.
- Discussions: These are normal comments, you can add them on any listed service.
Comment Moderation
I was strugling to keep up with moderation on the old site. For this, we've implemented an AI-powered moderation system that:
- Auto-approves legitimate comments instantly
- Flags suspicious content for human review
- Keeps discussions valuable by minimizing spam
The AI still can mark comments for human review, but most comments will get approved automatically by this system. The AI also makes summaries of the comments to help you understand the overall sentiment of the community.
Powerful Search & Filtering
Finding exactly what you need is now easier:
- Advanced filtering system with many parameters. You can even filter by attributes to pinpoint services with specific features.
The results are dynamic and shuffle services with identical scores for fairness.
See all listings
Listings are now added as 'Community Contributed' by default. This means that you can still find them in the search results, but they will be clearly marked as such.
Updated Scoring System
New dual-score approach provides more nuanced service evaluations:
- Privacy Score: Measures how well a service protects your personal information and data
-
Trust Score: Assesses reliability, security, and overall reputation
-
Combined into a weighted Overall Score for quick comparisons
- Completely transparent and open source calculation algorithm. No manual tweaking or hidden factors.
AI-Powered Terms of Service Analysis
Basically, a TLDR summary for Terms of Service:
- Automated system extracts the most important points from complex ToS documents
- Clear summaries
- Updated monthly to catch any changes
The ToS document is hashed and only will be updated if there are any changes.
Service Events and Timelines
Track the complete history of any service, on each service page you can see the timeline of events. There are two types of events:
- Automatic events: Created by the system whenever something about a service changes, like its description, supported currencies, attributes, verification status…
- Manual events: Added by admins when there’s important news, such as a service going offline, being hacked, acquired, shut down, or other major updates.
There is also a global timeline view available at /events
Notification System
Since we now have user accounts, we built a notifiaction system so you can stay informed about anything:
- Notifications for comment replies and status changes
- Watch any comment to get notified for new replies.
- Subscribe to services to monitor events and updates
- Notification customization.
Coming soon: Third-party privacy-preserving notifications integration with Telegram, Ntfy.sh, webhooks...
Service Suggestions
Anyone with an account can suggest a new service via the suggestion form. After submitting, you'll receive a tracking page where you can follow the status of your suggestion and communicate directly with admins.
All new suggestions start as "unlisted" — they won't appear in search results until reviewed. Our team checks each submission to ensure it's not spam or inappropriate. If similar services already exist, you'll be shown possible duplicates and can choose to submit your suggestion as an edit instead.
You can always check the progress of your suggestion, respond to moderator questions, and see when it goes live, everything will also be notified to your account. This process ensures high-quality listings and a collaborative approach to building the directory.
These are some of the main features we already have, but there are many more small changes and improvements that you will find when using the site.

2025-06-17 16:40:12Getting services and paying with cryptocurrencies comes with some risks that every user must understand. However, there are some simple steps you can take to reduce them.
The risks
Transactions are Irreversible
Cryptocurrency transactions are final and irreversible. Once you hit send, there's no chargeback option, no bank to call, and no dispute resolution (unless the recipient voluntarily returns your funds). This creates opportunities for bad actors to exploit.
Shotgun KYC
One of the most predatory practices in the crypto space is Shotgun KYC (classified as level 3 on KYCnot.me). Here's how it typically unfolds:
- You send your cryptocurrency to a service
- After receiving your funds, they suddenly claim your coins are "dirty" or flagged
- They hold your funds hostage, demanding extensive documentation
- Even after compliance, they may continue requesting more information indefinitely until you can't no longer provide what they are requesting
- Your funds remain frozen with no guarantee of release
Transaction Scanning
Most crypto services use blockchain analysis to scan your coins' transaction history, assigning risk scores based on past associations. A low score doesn't mean you did anything wrong, you could have unknowingly received "tainted" coins from a simple P2P trade, inheriting a history that wasn't your fault.
Other Concerns
- Limited Support: Many services operate with very small teams or even just a single person, offering minimal customer service. Even established services may ignore customer complaints or disputes.
- Exit Scams: A service that was apparently trustworthy and processing orders can disappear overnight, taking users' funds with them.
- No Regulatory Recourse: Very limited legal protections compared to traditional financial services
The rules
Rule #1: Batch Your Amounts
Avoid sending a large amount in a single transaction, instead, divide your trades into smaller batches. If something goes wrong with one batch, you haven't lost everything. Always remember that crypto transactions are final and irreversible.
Some services scam users selectively: they process smaller transactions normally to build trust, then freeze larger amounts when they detect high-value transfers.
Yes, batching means paying more fees, but it's almost always worth paying the extra rather than losing your entire amount to a scam or frozen trade.
A surprising number of people report losing significant funds in a single, large transaction. Start small, build confidence through successful transactions, and always maintain reasonable batch sizes even with "trusted" services.
Rule #2: Record Everything
When problems arise, services tend to mysteriously "lose" records, delete order pages, or even deny entire conversations. Keeping good records become very valuable against fraud and negligence.
Take screenshots and save them until you are satisfied with the service:
- Ensure timestamps are visible when possible
- Capture full pages, not just portions
- Make sure the URL is always visible
You can also use websites like archive.is to take snapshots of each step of the process, or use the Single File browser extension to snapshot the entire site in a single html file. This extension will preserve exact page appearance, includes all embedded content and is easy to share and store. For email conversations, exporting the raw
.eml
file is best, as it retains all the original headers and metadata.Make sure to keep all the blockchain evidence, such as transaction IDs and wallet addresses.
Remember: If it's not documented, it didn't happen in the eyes of dispute resolution. Make documentation a habit. This will grant you evidence for contacting support if there was an issue, and in the event of being scammed, effectively reporting the scam to the community.
Rule #3: Do Your Own Research
A quick investigation before operating with a service can save you from costly mistakes and frozen funds.
For service reviews, a starting point can be KYCnot.me. It's also wise to check popular forums like BitcoinTalk, TrustPilot, or Reddit. To search on specific sites, you can use
site
keyword on any search engine, for example, this shows all mentions of "Bisq" on BitcoinTalk.If you are about to use a service without existing reviews, you're taking a risk, but you could help others by documenting it. Write a detailed review and add supporting evidence to increase your credibility. Your feedback will help building a knowledge base that protects the community from bad actors and unreliable services. Leaving reviews on KYCnot.me is very easy and does not require any personal data.
Spend at least five minutes researching any new service before sending funds. This small time investment can reveal crucial information about reliability, processing times, and potential issues.
Rule #4: Ask for AML Checks
Most services will offer you a free AML score check before sending your funds, but they rarely advertise this. If you're dealing with a service known for freezing funds, requesting a pre-transaction AML check can save you from having your cryptocurrency held hostage.
Simply contact the service's support before sending any funds and explain your situation:
"I'd like to use your service but want to avoid KYC. Can you perform an AML check on my transaction before I send the funds?"
This check should always be free, if they ask for payment, consider it a red flag.
Never send funds to a third party to get an AML check. To prepare for the check, it's best to consolidate the funds into a single address in your own wallet. Then, you only need to share that public address for the analysis. Your funds should never leave your possession.
DIY AML Checking Options
You can also run these checks yourself using services like AMLBot (paid service) or the free AML scanners available in Blockchair's dApps section. These tools analyze your transaction history and provide risk scores based on various algorithms.
However, different AML services use different algorithms and metrics, so you might get varying risk scores for the same transaction. As you see in the image above, one service would flag your coins as medium-risk while another considers them clean. So to be 100% sure, it is always better to ask the service you want to interact with for the pre-trade AML check rather than checking it yourself.
Taking a few minutes to request an AML check can prevent problems like the permanent loss of your funds. A service that respects your privacy will have no problem with this reasonable request.
Rule #5: Seek fungibility
To protect yourself from arbitrary fund freezing and "dirty coin" accusations, simply use privacy coins whenever possible. While transparent blockchains expose your entire transaction history to scrutiny, privacy coins make these predatory scanning practices completely useless.
Traditional cryptocurrencies like Bitcoin and Ethereum operate on transparent blockchains where every transaction is publicly visible forever. This means not all coins are treated equally. A Bitcoin you received might be worth less than another Bitcoin simply because of its transaction history, even when you had nothing to do with that history.
Even if you try to break the history with mixers or coinjoins, you are leaving patterns that will also taint the coins. Once they are marked as "tainted" by blockchain analysis, that reputation follows them indefinitely, you can even be penalized for transactions that occurred years before you owned the cryptocurrency, creating an unfair system of inherited blame.
Monero's privacy-by-default architecture makes transaction scanning impossible. Legitimate services that respect user privacy usually welcome privacy coins. Services that discriminate against privacy coins often have ulterior motives.
Using privacy coins is often simpler because you don't need to worry about coin history or risk scores. So, any chance you get to use a privacy coin such as Monero, just do it.
Conclusion
Even by following all these rules, you're still assuming a certain level of risk. However, by following these simple safety measures, you will dramatically reduce your exposure to scams, fund freezes, and predatory practices. And, if a problem occurs, having good evidence is your best defense. Records like screenshots and transaction histories are essential for resolving disputes and reporting scams to protect others.

2025-06-15 10:02:09The latest AI chips, 8K displays, and neural processing units make your device feel like a pocket supercomputer. So surely, with all this advancement, you can finally mine bitcoin on your phone profitably, right?
The 2025 Hardware Reality: Can You Mine Bitcoin on Your Phone
Despite remarkable advances in smartphone technology, the fundamental physics of bitcoin mining haven’t changed. In 2025, flagship devices with their cutting-edge 2nm processors can achieve approximately 25-40 megahashes per second when you mine bitcoin on your phone—a notable improvement from previous generations, but still laughably inadequate.
Meanwhile, 2025’s top-tier ASIC miners have evolved dramatically. The latest Bitmain Antminer S23 series and Canaan AvalonMiner A15 Pro deliver 200-300 terahashes per second while consuming 4,000-5,500 watts. That’s a performance gap of roughly 1:8,000,000 between when you mine bitcoin on your phone and professional mining equipment.
To put this in perspective that hits home: if you mine bitcoin on your phone and it earned you one penny, professional miners would earn $80,000 in the same time period with the same effort. It’s not just an efficiency problem—it’s a complete category mismatch.
According to Pocket Option’s 2025 analysis, when you mine bitcoin on your phone in 2025, you generate approximately $0.003-0.006 in daily revenue while consuming $0.45-0.85 in electricity through constant charging cycles. Factor in the accelerated device wear (estimated at $0.75-1.20 daily depreciation), and you’re looking at losses of $1.20-2.00 per day just for the privilege of running mining software.

Bitcoin’s 2025 Network: Harder Than Ever
Bitcoin’s network difficulty in 2025 has reached unprecedented levels. After the April 2024 halving event that reduced block rewards from 6.25 to 3.125 BTC, mining became significantly more competitive. The global hash rate now exceeds 800 exahashes per second—that’s 800 followed by 18 zeros worth of computational power securing the network.
Here’s what this means in practical terms: Bitcoin’s mining difficulty adjusts every 2,016 blocks (roughly every two weeks) to maintain the 10-minute block time. As more efficient miners join the network, difficulty increases proportionally. In 2025, mining difficulty has increased compared to 2024, making small-scale mining even less viable.
The math is unforgiving:
- Global Bitcoin hash rate: 828.96 EH/s
- Your smartphone’s contribution: ~0.000000003%
- Probability of solo mining a block: Virtually zero
- Expected time to mine one Bitcoin: Several million years
Even joining mining pools doesn’t solve the economic problem. Pool fees typically range from 1-3%, and your minuscule contribution would earn proportionally tiny rewards—far below the electricity and device depreciation costs.
The 2025 Scam Evolution: More Sophisticated, More Dangerous
Fraudsters now leverage AI-generated content, fake influencer endorsements, and impressive-looking apps that simulate realistic mining activity to entice you to mine bitcoin on your phone.
New 2025 scam tactics include:
AI-Powered Fake Testimonials: Deepfake videos of supposed successful mobile miners showing fabricated earnings statements and encouraging downloads of malicious apps.
Gamified Mining Interfaces: Apps that look and feel like legitimate games but secretly harvest personal data while simulating mining progress that can never be withdrawn.
Social Media Manipulation: Coordinated campaigns across TikTok, Instagram, and YouTube featuring fake “financial influencers” promoting mobile mining apps to younger audiences.
Subscription Trap Mining: Apps offering “free trials” that automatically charge $19.99-49.99 monthly for “premium mining speeds” while delivering no actual mining capability.
Recent cybersecurity research shows that over 180 fake mining apps were discovered across major app stores in 2025, with some accumulating more than 500,000 downloads before being removed.
Red flags that scream “scam” in 2025:
- Apps claiming “revolutionary mobile mining breakthrough”
- Promises of earning “$10-50 daily” from phone mining
- Requirements to recruit friends or watch ads to unlock withdrawals
- Apps that don’t require connecting to actual mining pools
- Testimonials that seem too polished or use stock photo models
- Apps requesting permissions unrelated to mining (contacts, camera, microphone)
The 2025 Professional Mining Landscape
To understand why, consider what professional bitcoin mining looks like in 2025. Industrial mining operations now resemble high-tech data centers with:
Cutting-edge hardware:
- Bitmain Antminer S23 Pro: 280 TH/s at 4,800W
- MicroBT WhatsMiner M56S++: 250 TH/s at 4,500W
- Canaan AvalonMiner A1566: 185 TH/s at 3,420W
Infrastructure requirements:
- Megawatt-scale power contracts with industrial electricity rates
- Liquid cooling systems maintaining 24/7 optimal temperatures
- Redundant internet connections ensuring zero downtime
- Professional facility management with 24/7 monitoring
For a small operation, you might need at least $10,000 to $20,000 to buy a few ASIC miners, set up cooling systems, and cover electricity costs. These operations employ teams of engineers, maintain relationships with power companies, and operate with margins measured in single-digit percentages.
2025’s Legitimate Mobile Bitcoin Strategies
While it remains impossible to mine bitcoin on your phone profitably, 2025 offers exciting legitimate ways to engage with bitcoin through your smartphone:
Lightning Network Participation: Apps like Phoenix, Breez, and Zeus allow you to run Lightning nodes on mobile devices, earning small routing fees while supporting bitcoin’s payment layer.
Bitcoin DCA Automation: Services enable automated dollar-cost averaging with amounts as small as $1 daily. Historical data shows $10 weekly bitcoin purchases consistently outperform any mobile mining attempt by 1,500-2,000%.
Educational Mining Simulators: Legitimate apps like “Bitcoin Mining Simulator” teach mining concepts without false earning promises. These educational tools help users understand hash rates, difficulty adjustments, and mining economics.
Stacking Sats Rewards: Apps offering bitcoin rewards for shopping, learning, or completing tasks.
Lightning Gaming: Bitcoin-native mobile games where players can earn sats through skilled gameplay, with some players earning $10 monthly.onfirm that even the most optimized mobile mining setups in 2025 lose money consistently and predictably.
The Bottom Line
When you mine bitcoin on your phone fundamental economics remain unchanged: it’s impossible to profit. The laws of physics, network competition, and energy efficiency create insurmountable barriers that no app can overcome.
However, 2025 offers unprecedented opportunities to engage with bitcoin meaningfully through your smartphone. Focus on education, legitimate earning opportunities, and strategic investment rather than chasing the impossible dream of phone-based mining.
The bitcoin community’s greatest strength lies in its commitment to truth over hype. When someone promises profits to mine bitcoin on your phone in 2025, they’re either uninformed or deliberately misleading you. Trust the mathematics, learn from the community, and build your bitcoin knowledge and holdings through proven methods.
The real opportunity in 2025 isn’t to mine bitcoin on your phone—it’s understanding bitcoin deeply enough to participate confidently in the most important monetary revolution of our lifetime. Your smartphone is the perfect tool for that education; it’s just not a mining rig.

2025-06-17 16:35:04Bitcoin foi criado para oferecer uma alternativa segura e descentralizada ao dinheiro tradicional, permitindo transações financeiras sem a necessidade de intermediários. DeFi, por outro lado, surgiu como uma expansão deste conceito, propondo serviços financeiros descentralizados, como empréstimos, trocas e geração de rendimento. No entanto, apesar das promessas de inovação, DeFi apresenta inúmeros riscos, tornando-se uma aposta perigosa para quem valoriza a segurança do seu Bitcoin.
O que é DeFi?
DeFi refere-se a um conjunto de aplicações financeiras que funcionam sem a intermediação de bancos ou instituições tradicionais. Estas plataformas utilizam contratos inteligentes para automatizar transações, permitindo que qualquer pessoa aceda a serviços financeiros sem depender de terceiros. Na teoria, DeFi promete mais liberdade financeira, mas na prática está cheio de riscos, fraudes e vulnerabilidades técnicas que podem comprometer os fundos dos utilizadores.
Os riscos de DeFi para quem tem Bitcoin
Bitcoin é a moeda digital mais segura do mundo, protegida por uma rede descentralizada e resistente à censura. Ao contrário de DeFi, que ainda está em fase experimental e já sofreu inúmeros ataques, Bitcoin mantém-se sólido e confiável. Quando alguém coloca Bitcoin em plataformas DeFi, está a abrir mão da segurança da sua custódia direta e a confiar em sistemas mais frágeis. os principais riscos incluem:
Hackers e falhas de código: contratos inteligentes são escritos por programadores e podem conter falhas que permitem roubos massivos. ao longo dos anos, milhares de milhões de dólares já foram perdidos devido a vulnerabilidades em plataformas DeFi.
Riscos de liquidação: muitas aplicações DeFi funcionam com sistemas de colateralização, onde os utilizadores bloqueiam Bitcoin para obterem empréstimos. se o mercado se tornar volátil, esses Bitcoins podem ser liquidados a preços abaixo do esperado, causando perdas irreversíveis.
Fraudes e rug pulls: DeFi está repleto de projetos obscuros onde os criadores desaparecem com os fundos dos utilizadores. sem regulamentação e sem garantias, quem deposita Bitcoin nessas plataformas pode nunca mais recuperar os seus fundos.
Guardar Bitcoin em segurança é a melhor escolha
Bitcoin foi criado para ser auto-custodiado, ou seja, cada utilizador deve ter controlo direto sobre os seus fundos sem depender de terceiros. Ao enviar Bitcoin para plataformas DeFi, perde-se essa segurança e expõe-se o ativo a riscos desnecessários. A melhor forma de proteger Bitcoin é armazená-lo numa carteira segura, preferencialmente offline (cold storage), evitando qualquer tipo de exposição a contratos inteligentes ou sistemas vulneráveis.
Resumindo, DeFi pode parecer inovador, mas os riscos superam largamente os potenciais benefícios, especialmente para quem valoriza a segurança de Bitcoin. ao invés de arriscar perder fundos em plataformas inseguras, o mais sensato é manter Bitcoin armazenado de forma segura, garantindo a sua preservação a longo prazo. Enquanto Bitcoin continua a ser a melhor reserva de valor digital do mundo, DeFi ainda se revela um ambiente instável e perigoso, onde poucos saem ganhadores e muitos acabam por perder.
Muito obrigado por teres lido o texto até aqui, espero que esteja tudo bem contigo e um abraço enorme do teu madeirense bitcoiner maximalista favorito. Viva a liberdade!

2025-06-17 16:01:54Japanese investment firm Metaplanet has announced a massive $5.4 billion plan to increase its bitcoin holdings to 210,000 BTC by the end of 2027 — that’s about 1% of the total bitcoin supply.
Metaplanet on X
The Tokyo-listed company is accelerating its already aggressive bitcoin plan, with CEO Simon Gerovich calling the initiative “Asia’s largest-ever equity raise to buy Bitcoin — again!”
The company’s new capital raise, called the “555 Million Plan”, involves issuing 555 million shares through moving strike warrants. That’s basically a type of option where people can buy shares later, and the price they pay depends on the stock’s price at that time.
So with moving strike warrants, the price at which people can buy the stock goes up or down depending on how the company’s stock is doing. It gives investors more flexibility — and it can make the warrants more attractive — because they don’t get stuck with a bad deal if the stock price drops.
This way the company can raise capital gradually over the next 2 years without impacting the stock market and existing shareholders.
The funds raised will be used to buy bitcoin, with some to redeem bonds and other income-generating strategies like selling put options.
This is a big step up from Metaplanet’s previous targets. Initially aiming to reach 10,000 BTC by the end of 2025, the company now plans to reach:
- 30,000 BTC by end of 2025
- 100,000 BTC by end of 2026
- 210,000 BTC by end of 2027
The Japanese investment firm hopes to be in the “Bitcoin 1% club” which means holding at least 1% of the total 21 million bitcoin supply.
Metaplanet bitcoin targets
Metaplanet is already making good progress. As of June 2025, the company holds 8,888 BTC, acquired at a cost of about ¥122.2 billion (around $849 million) and has already reached 89% of its original 10,000 BTC target for 2025.
This comes after the success of the company’s previous “210 Million Plan” which raised ¥93.3 billion ($650 million) in 60 trading days by issuing 210 million shares.
During that time, the company’s bitcoin holdings grew from 1,762 BTC to 7,800 BTC and the BTC Yield (a key performance metric showing growth in bitcoin per share) increased by 189%.
Year to date the BTC Yield is 225.4%.
Metaplanet’s BTC Yield graph
The stock has reflected this momentum, up 275% since early 2025 and 1,619% over the past year.
Metaplanet’s stock price chart — TradingView
Metaplanet is now one of the most actively traded stocks in Japan and has become a top-ten corporate bitcoin holder globally, recently surpassing Block Inc., the company founded by Jack Dorsey.
Metaplanet sees this as part of a bigger shift in capital markets.
By being a “bitcoin treasury vehicle” listed on the Tokyo Stock Exchange, it aims to offer investors exposure to bitcoin through regulated equity markets. This is especially useful in Japan where retail investors are often restricted from accessing bitcoin directly.
“Bitcoin is repricing the global cost of capital,” the company said in a statement. “Through our 555 Million Plan, Metaplanet is doubling down on a high-conviction, equity-driven capital markets strategy to accelerate our Bitcoin accumulation trajectory.”

2025-06-14 21:39:15## ParentCoin; limitless
There's this almost altcoin-like pitch of parenthood these days. I might’ve fallen for the shiny marketing of parenthood — cute baby pics, promises of legacy, the whole “you’ll change the world” vibe. I even heard a would-be mom tell me once (true story) "You know having children, you don't have to be afraid of it, as a dad it doesn't cost as much as you think". \ These people actually believe that. Just like they've fallen for every fiat-scam out there: housing, cars, holidays in France, Nike shoes, 50% taxation, religion and main stream media subscriptions.\ \ It’s 2025, and I’m revisiting this like I’d revisit an old Lightning Network post. \ \ Having kids is like chasing an altcoin airdrop with a slick but buzzword laden whitepaper and a charismatic founder who’s probably exit-scamming as soon as he gets enough of your money in their bank account (yeah you see what I did there). If you're lucky that founder might twerk from time to time to get your attention. But don't hope for too much. Now change that diaper and work an extra job to pay for all of it while inflation murders you.\ \ While you do all that, the most damaging thing about the Having Children Shitcoin (HCS) is the time it takes. It literally can't be shorted like some token on an exchange. It laughs, plays around with your tech gadgets, has to be potty trained (like some altcoin founders) and needs attention, education and a lot of proof of work.\ But the damage is the time. \ The time it takes to do all that, is actually replacing value with time. \ Bitcoin might be a product of proof of work, HCS is not a product but the actual proof of work without the value proposition.\ On top of that, the founder usually lives rent-free in your head your whole life, or even worse: you literally live together with her/him.\ Imagine Satoshi Nakamoto living at your house right now. Like... hi Satoshi.. love your bitcoin man.\ "Yeah, thanks moth**f****r, when are going to buy more skittle and some toilet paper? We ran out 10 minutes ago when I shit all over your dirty toilet, ..."\ "Eh, But Satoshi, why don't you go to the shop to..."\ "Shut up you f'ing a--hole, you made me! You made me what I am today! You liked me when I invented thàh bitcoin right? Now get me some toilet paper and here's a list of items I want from the supermarket! Lazy dumb idiot."\ "You'll clean up the kitchen right?"\ "Yeah yeah, rolls eyes, after my Netflix series man... now get out"\ \ This might sound far-fetched but founders of shitcoins steal your money, while children steal your time ànd money while you have to endure the founders as well.
Time is slowly damaging you while you live your life further and further away from the hard-money proposition. Hell, you even will need to sell some hard money to get by. Because it's a rotten world and children make you short sighted about the future (it limits you to maximum 3 years ahead in my experience with people around me).
Long-term is your enemy Short-term is your prison
You’re hyped for the long-term gains—multi-generational dynasties, just like the elites—but the fine print? It’s a mess. I’m here to unpack the hope, the scepticism, and the grim reality of raising kids in a world that feels like it’s speedrunning towards the absolute bottom. Let me make that clearer:
Our power (as bitcoiners) doesn't grow with these new generations, because we're being out-Idiocracy'd at a rate we can’t reproduce our way out of. Bitcoiners don’t scale. Even if you produce two children that both become die-hard bitcoin maximalists (with a nasal voice and a fondness for TD-sequential analysis.
The Mirage of Birth Having a kid is like snagging a hyped-up crypto airdrop. You’re told it’s “free” value — new life, pure joy, a legacy token dropped into your wallet. Everyone’s tweeting about it, posting ultrasound pics like they just scored 10,000 USDC worth of free shitcoin tokens.
But then the transaction fees hit, getting another place to live more accommodating, getting a school, adopt a dad body demeaner while torpedoing your social life and having no fun other than baking cakes and getting less pussy than a laser pointer with dead batteries. Adjust for inflation), sleepless nights, a vortex of money being vaporized and a lifetime of HODLing a position you can’t dump nor short. You’re basically the holder of last resort for a diatribe of chaos. You’re the entry, the trade, and exit liquidity. The real kicker? Society’s cheering you on while you’re stuck debugging your life and seeing your time drained. You’re frozen in time, while you should be scaling ideas. \ \ Or getting more out of life than being the channelling of funds to a future fiat oppressed kid. Meanwhile, parents (if they stay together that is... with relations with kids having their own version of the bitcoin “halving”, be it every 7 years or so. The parents follow the higher noble goal and get some love and nice moments in return. \ \ They’re stacking diapers instead of sats, living above a dry cleaner next to a subway station that rattles your soul. You can’t short kids, no matter how much you see the “childfree” crowd thriving. The childfree crowd is also not always that neutral, as many of them want this same life, because the marketing, as with many shitcoins is excellent. It makes life more fun, more fulfilling, more whole, while promising you cheap, fast and always immutable transactions. You’re getting duped. \ You buy more stuff, more hobbies no one cares about, and smile at other parents at these gatherings like you’re at the whale room at a bitcoin conference in a bear market. Keep smiling, bitches. That’s you’re life now. The numbers don’t lie. Society sells parenthood as a Bitcoin-level HODL, but the safety net is thinner than a layer-2 solution created by an Albanian exchange.
Raising kids is like betting your airdropped tokens will moon into a blue-chip asset that takes care of you when you’re old. You’re hoping they’ll HODL your hand, not rug-pull you into a nursing home when their “value” spikes. It’s a gamble: will they be decent humans or turn into TikTok zombies? Back in the day, kids were economic assets, working the farm or whatever. Now? You’re praying they don’t ghost you after college or at least recognize all the proof of work you did for them. And yes, you can have a big impact on them, that’s something to be proud of if it works out. But in the end, you are you, a person, with dreams, hopes and needs. \ And your children are too,... they’ll always win. \ \ Teaching them to ride a bike is fun, but it’s like a shitcoin pumping on a founder’s tweet: fleeting, followed by a crash whenever you see the effects of your years of de-progress and social isolation. Socializing with other parents is like making friends with a fellow prisoner of war in some jungle camp, ... you’ll have to be nice because it’s all you have left of society’s pleasantries. So you make small talk or a little joke about a toy someone’s kid has brought to the playground. The real world would see these people piss all over your grave if they could. They’re the figurehead on a ship of fools. And you play along because you’re a total bitch that got stuck in the routine of the famous HCS. Finding trust is hard, certainly in a city’s virtual prison camp where you play Russian roulette for other people’s amusement. It’s like running a Lightning node — fun in theory, but you’re babysitting a system that crashes when you need it most. The highs are real, but “kinda fun” doesn’t cut it when you’re debugging life. \ \ The 35k to 200k € it will cost you throughout your life, is not measurable as gains or losses. Look at the lovely baby pictures, look at their school results, the painting they made especially for you saying “I love you, for the best dad/mom in the whole world”. It hits straight to your brain’s nucleus accumbens. It’s all the balanced injection of the right shot of chemical balanced reward center (ventral tegmental area) food. \ And people with kids wanted that because that’s what the system and urges are. Kids are a leveraged position with no stop-loss, unlike an airdrop you can dump when the hype fades. You’re all-in, praying society doesn’t crash before your “asset” matures. In the meanwhile, you get the occasional surprise through your mesolimbic pathway. \ \ "Happy you" proof of stakes' the unhappy you later. You could be in the Maldives diving into clear water while talking to another “founder”. Funny how that works. \ Meanwhile, the childfree are staking their tokens and chilling. \ Parents aren’t building dynasties; we’re just trying not to get rug-pulled by daycare costs and rotten school-systems that learn our kids to be obedient consumers and non-thinking parrots. It’s a financial social anti-grind with no cure, and the charts, unlike fiat-corporate nonsense, don’t lie.
The elites stack power like blue-chip stocks, minting wealth across centuries. Us? Our kids might be fighting over the leftovers while they battle their way through university diversity and mediocracy. Future generations are supposed to carry the torch, but consumerism and cultural decay make it feel like we’re being out-Idiocracy’d. \ We need to think long-term, teach kids to code, stack sats, and question the system. But above all else, we need them to learn that being more evil is more just. Being complacent in this farce of a system means always, and I mean always, that the multi-generational monsters will prevail. \ \ They’re more stubborn, faster, better educated and they take the shortcuts you can’t have. We have hard money, they have “hard world”.
Conclusion
Eighteen years into this parenting thing (or eight minutes—who’s counting?), it’s clear: kids are a shitcoin airdrop with no exit strategy for you. \ The highs are sweet, the costs are brutal, and the long-term. A gamble on humanity in a world trending toward a broad brush of average things made normal.
Maybe it’s not about winning the bitcoin standard, but betting on something bigger than yourself within yourself, even if that market’s rigged with traps and detractors everywhere. Stack sats, stack diapers, and pray your kids don’t rug-pull your heart. \ Because, let’s face it, we’re not the Rothschilds — we’re just HODLing and hoping. \ While we should be fighting with the hardest money. \ While your baby cries for more food, I hear Michael Jackson sing “If you can’t feed your baby hi hee-hee, then don’t have a baybaah”. \ \ The sad part is, that we're all torn between chasing the fiat-created dreams and the reality that everything is in fact a shitcoin sapping either your time, money or effort. \ Even within the bitcoin space, we don't realize what the next step should be.\ It certainly isn't big families. That's for sure.

2025-06-17 16:01:34Flash, the all-in-one Bitcoin payment platform, just launched Flash Invoicing. The first invoicing tool for Bitcoin that is completely free, non-custodial, KYC-free, and fully integrated into a comprehensive bitcoin business suite.
Freelancers, contractors and independent workers can now send professional bitcoin invoices with 0% platform fees, no identity verification, and no third-party custody — a first in the Bitcoin ecosystem.
According to Deel, crypto payments to freelancers grew 10x in 2023, with bitcoin remaining the most-used currency. But despite this surge, the tools available for invoicing remain outdated.
Most freelancers still paste Bitcoin addresses into PDF footers or emails, hoping their client sends the right amount. Others use custodial platforms that charge high fees and require full identity verification.
“We’ve seen too many people paste BTC addresses into documents and call it invoicing,” said Pierre Corbin, CEO of Flash.
“It’s messy, reduces privacy and very inconvenient both for payee and payer.”, he explains.
Most Bitcoin invoicing tools charge a percentage per transaction — or lock users into subscription plans. That means freelancers lose a portion of every invoice just for the privilege of getting paid.
The other option is host open-source invoicing tools or use a google sheet template. While the former requires a hardware investment, the latter lacks functionality. Flash Invoicing is aiming to provide a better solution to address the invoicing needs for modern businesses and freelancers.
“Freelancers work hard enough. The last thing they need is a platform skimming off their earnings,” said Pierre.
“That’s why we dropped our fee from 1.5% to 0% — and launched the first invoicing tool that’s truly free, without compromising on privacy or control.”
“As a freelancer myself, I love using the Flash invoicing feature. It keeps all my clients in one place, allows me to easily edit invoices and track payments. Much more professional than sending a lightning address in the footer of a PDF invoice.” — Ada, freelancer & Flash user
Whether you’re a solo designer in Nairobi, a Web3 developer in Buenos Aires, or a consultant billing startups in Berlin, Flash Invoicing gives you a way to accept Bitcoin — without giving up control, privacy, or revenue.
And because it’s fully integrated with the broader Flash suite, freelancers can easily scale from invoicing to setting up stores, receiving donations, or gating premium content.
About Flash
Flash is the only non-custodial, KYC-free Bitcoin payment platform built for freelancers, creators, and businesses. With tools for invoicing, donations, stores, and POS, Flash gives users full control over how they earn and operate in Bitcoin — with no fees and no middlemen.

Saylor highlighted the critical role of trust and leadership in attracting global capital, citing his own journey of turning a $400 million investment into a $40 billion market backed position through Bitcoin.
“Today, I will stay in touch with Bilal,” he said. “Pakistan has many brilliant people and a lot of people to do business with you. My company had less than $400 million to invest, but the markets gave me $40 billion because they trust us. And so the most important thing is leadership, intellectual leadership and that they trust you.”
Saylor further emphasized that trust and clarity of vision are what drive global capital flows.
“If the world trusts you and they hear your words, and you speak particularly, the capital and the capability will flow to Pakistan,” said Saylor. “It’s there, it wants to find a home and that’s what happened with our company. Our success is because we were clear and committed. And once the market decides who the leader is. They get behind the leader and they send their money to you. And I think they’d do it to Pakistan too. You have the most important thing, which is you have a commitment and a will and clarity here. So, I look forward to working with you.”
The new stance is a stark change for Pakistan, which had previously banned Bitcoin trading in 2018. On March 20, Bilal Bin Saqib told Bloomberg that Pakistan was planning to legalize Bitcoin and try to implement a regulatory framework to attract investors.
“Pakistan is done sitting on the sidelines,” said Saqib. “We want to attract international investment because Pakistan is a low-cost, high-growth market with 60% of the population under 30… Trump is making crypto a national priority, and every country, including Pakistan, will have to follow suit.”
During the 2025 Bitcoin Conference in Las Vegas, Saqib announced that Pakistan was creating a strategic Bitcoin reserve.
“Today, I will announce that the Pakistan government is setting up their own government led Bitcoin strategic reserve… and this wallet, the national Bitcoin wallet,” said Saqib. “It’s not for speculation or hype. We will be holding this Bitcoin and we will never ever sell them.”

Trump Media Files to Launch Bitcoin and Ethereum ETFTrump Media & Technology Group has filed a registration statement with the U.S. Securities and Exchange Commission to launch the Truth Social Bitcoin and Ethereum ETF, B.T.
The ETF will directly hold Bitcoin and Ether, with an initial allocation of 75% Bitcoin and 25% Ether. Shares of the fund will be offered to investors to track the performance of these assets and are expected to trade on NYSE Arca once approved.
JUST IN:
Registration statement for Trump Media's Bitcoin Treasury deal was declared effective by the SEC
pic.twitter.com/PFyy44qXxH
— Bitcoin Magazine (@BitcoinMagazine) June 13, 2025
Crypto.com has been selected as the exclusive custodian, prime execution agent, staking, and liquidity provider for the ETF. Yorkville America Digital, LLC is the sponsor of the fund.
According to the company’s announcement, “The launch of the Truth Social Bitcoin and Ethereum ETF is pending effectiveness of the Registration Statement as well as approval of a Form 19b-4 filing with the SEC.”
The fund is structured as a Nevada business trust. Shares will be issued and redeemed in blocks of 10,000 by authorized participants, with cash used for creation and redemption. The ETF may offer in-kind transactions in the future, pending additional regulatory approval.
Trump Media acknowledged, “A registration statement relating to the Shares has been filed with the SEC but has not yet become effective. The Shares may not be sold, nor may offers to buy be accepted, prior to the time the registration statement becomes effective.”
The ETF is not registered under the Investment Company Act of 1940, which typically governs mutual funds and traditional ETFs by imposing rules on investor protections, disclosures, and fund operations. Because the ETF holds Bitcoin and Ether directly rather than securities, it qualifies as a grantor trust and is exempt from these requirements.
The ETF filing also reflects Trump Media’s strategy to establish a presence in the digital asset space beyond social media and streaming. With the development of its financial services arm, Truth.Fi, the company is clearly positioning itself to compete in the growing digital asset space.
If approved, the Truth Social ETF would give investors a direct, regulated path into both Bitcoin and Ether through one fund. As Trump Media expands its presence in financial services, the move signals a clear intention to compete in the space.

2025-06-17 15:55:26O Bitcoin tem se destacado como uma ferramenta econômica nova em economias em desenvolvimento. Essas nações muitas vezes enfrentam dificuldades como alta inflação, sistemas bancários frágeis e acesso restrito a serviços financeiros. Com suas características especiais, como descentralização, resistência à censura e oferta limitada, o Bitcoin aparece como uma solução alternativo para proteger patrimônio, facilitar transações internacionais e promover a inclusão financeira.
Desafios enfrentados por economias emergentes
Inflação e desvalorização da moeda:
Muitos países em desenvolvimento enfrentam políticas monetárias instáveis, levando à desvalorização de suas moedas.
A inflação diminui o poder de compra das pessoas, tornando difícil manter patrimônio e planejar finanças a longo prazo.
Acesso dimitado ao sistema bancário:
Em várias áreas, especialmente rurais, uma parte significativa da população não tem acesso a bancos ou serviços financeiros básicos.
Isso dificulta a guarda de dinheiro, a obtenção de crédito e a realização de transações seguras.
Remessas e transações internacionais caras:
Muitos cidadãos de economias em desenvolvimento dependem de remessas enviadas por familiares que trabalham no exterior.
As taxas cobradas por intermediários financeiros podem ser elevadas, diminuindo o valor recebido pelas famílias.
Como o Bitcoin beneficia economias emergentes
Proteção contra inflação:
Com sua oferta limitada a 21 milhões de unidades, o Bitcoin serve como um ativo deflacionário, permitindo que indivíduos protejam seu patrimônio contra a desvalorização da moeda local.
Em países como Venezuela e Argentina, onde as taxas de inflação são muito altas, o Bitcoin tem sido usado como uma reserva de valor.
Inclusão financeira:
O Bitcoin elimina a necessidade de intermediários financeiros, permitindo que qualquer pessoa com acesso à internet participe da economia global.
Indivíduos sem conta bancária podem usar carteiras digitais para guardar e transacionar valor, promovendo a inclusão financeira em larga escala.
Transações internacionais simplificadas:
O Bitcoin permite transferências de valor rápidas e baratas entre países, sem a necessidade de intermediários como bancos ou empresas de remessas.
Isso ajuda trabalhadores que enviam dinheiro para casa, garantindo que mais recursos cheguem aos destinatários finais.
Resistência à censura e controle governamental:
Em economias em desenvolvimento com governos autoritários ou instabilidade política, o Bitcoin permite que cidadãos mantenham controle sobre seu dinheiro, sem medo de confiscos ou restrições injustas.
Sua rede descentralizada impede que uma única autoridade controle ou manipule o sistema.
Casos reais de uso em economias emergentes
El Salvador:
Em 2021, El Salvador se tornou o primeiro país a tornar o Bitcoin uma moeda oficial. Essa escolha tinha o objetivo de diminuir os custos das remessas internacionais e aumentar a inclusão financeira.
A iniciativa também atraiu investimentos e turismo ligados ao Bitcoin, embora enfrente críticas e dificuldades de implementação.
Nigéria:
Na Nigéria, o uso do Bitcoin aumentou bastante devido à inflação e às restrições do governo sobre transações financeiras.
Jovens empreendedores e trabalhadores autônomos usam o Bitcoin para receber pagamentos internacionais e evitar limitações impostas por bancos locais.
Venezuela:
Com a crise econômica e a hiperinflação, o Bitcoin se tornou uma ferramenta importante para proteger a riqueza e fazer transações no país.
Muitas famílias venezuelanas dependem do Bitcoin para comprar produtos essenciais e enviar ou receber dinheiro do exterior.
Desafios do uso de Bitcoin em economias emergentes
Volatilidade:
A alta volatilidade no preço do Bitcoin pode fazer com que seu uso seja arriscado para pessoas que dependem dele como reserva de valor.
Essa instabilidade pode desestimular seu uso em transações do dia a dia.
Infraestrutura Limitada:
O uso do Bitcoin precisa de acesso à internet e dispositivos digitais, o que pode ser um impedimento em áreas com infraestrutura limitada.
Educação e Adaptação:
A adoção do Bitcoin requer um certo nível de conhecimento técnico, e a falta de educação financeira pode dificultar sua utilização em larga escala.
Muitas pessoas ainda preferem moedas tradicionais por falta de conhecimento ou desconfiança em relação ao Bitcoin.
O futuro do Bitcoin em economias emergentes
Desenvolvimento de infraestrutura:
Projetos que promovem o acesso à internet e a dispositivos digitais podem aumentar bastante a adoção do Bitcoin nessas áreas.
Estabilidade e confiança:
Conforme o mercado se desenvolve, a volatilidade do Bitcoin pode diminuir, tornando-o mais útil como meio de troca e reserva de valor.
Educação e capacitação:
Iniciativas de educação financeira podem ajudar as pessoas a entender e aproveitar os benefícios do Bitcoin, facilitando sua incorporação ao dia a dia.
Resumindo, o Bitcoin tem um papel transformador em economias emergentes, oferecendo uma alternativa forte aos sistemas financeiros tradicionais. Sua capacidade de proteger contra a inflação, promover a inclusão financeira e facilitar transações internacionais faz dele uma ferramenta essencial para milhões de pessoas.
Embora desafios como volatilidade e infraestrutura limitada precisem ser superados, o potencial do Bitcoin de empoderar indivíduos em economias emergentes é claro. Como um ativo digital descentralizado, ele representa não apenas uma inovação tecnológica, mas também uma esperança para um futuro econômico mais justo e acessível.

2025-06-17 15:47:27O Bitcoin é amplamente reconhecido como a primeira e mais importante inovação no campo das moedas digitais. Criado por Satoshi Nakamoto em 2009, ele estabeleceu as bases para um sistema financeiro descentralizado. Desde então, surgiram milhares de outras moedas digitais, muitas vezes referidas como criptomoedas ou até mesmo "shitcoins" por críticos que apontam sua volatilidade, falta de utilidade clara ou centralização. Essa comparação entre o Bitcoin e outras criptomoedas é essencial para entender os valores exclusivos que o Bitcoin representa.
O Bitcoin foi criado para ser uma alternativa ao sistema financeiro tradicional. Sua missão central é fornecer uma moeda descentralizada, resistente à censura e livre de intermediários como bancos ou governos.
Por outro lado, a maioria das outras criptomoedas/shitcoins surgiu com diferentes objetivos, que vão desde experimentos tecnológicos até planos de enriquecimento rápido. Muitas dessas moedas não têm a mesma descentralização e segurança do Bitcoin, sendo frequentemente geridas por equipes ou organizações centralizadas, o que as torna mais suscetíveis à manipulação e falhas de segurança.
Descentralização e segurança
Bitcoin: a rede Bitcoin é suportada por milhares de nós espalhados pelo mundo, garantindo verdadeira descentralização.
Seu algoritmo de consenso, Proof of Work (PoW), é amplamente testado e proporciona altos níveis de segurança contra ataques.
Não há controle centralizado, o que significa que nenhuma entidade pode alterar suas regras fundamentais.
Outras criptomoedas/shitcoins
Praticamente todas sacrificam descentralização em troca de velocidade ou funcionalidades adicionais.
Algumas utilizam mecanismos de consenso alternativos, como Proof of Stake (PoS), que, embora sejam mais eficientes em termos energéticos, são frequentemente criticados por favorecer a centralização e oferecer menor segurança.
Em muitos casos, há equipes de desenvolvimento centralizadas que podem modificar o código, criar mais unidades da moeda ou até encerrar o projeto, comprometendo a confiança dos usuários.
Oferta e escassez
Bitcoin: o Bitcoin tem uma quantidade limitada de 21 milhões de unidades, garantindo sua escassez.
Essa característica, junto com a crescente demanda, posiciona o Bitcoin como uma reserva de valor confiável, frequentemente comparado ao ouro digital.
Outras criptomoedas/shitcoins
Muitas não têm limites claros em sua oferta, resultando em inflação descontrolada.
Algumas “moedas” são intencionalmente inflacionárias, o que pode reduzir seu valor com o tempo.
Em muitos casos, essas “moedas” são pré-mineradas ou distribuídas de maneira desigual, favorecendo os criadores em detrimento da comunidade.
Finalidade e utilidade
Bitcoin: o Bitcoin é, acima de tudo, uma forma de dinheiro digital e reserva de valor.
Sua rede é confiável e simples, com o foco principal em ser um meio de troca e proteção contra a inflação.
Sua solidez o torna ideal para transações e armazenamento de valor a longo prazo.
Outras criptomoedas/shitcoins
Muitas shitcoins são apresentadas como soluções para casos específicos, como contratos inteligentes, jogos ou finanças descentralizadas.
Apesar de promessas ousadas, muitos falham em oferecer utilidade real ou em competir com soluções centralizadas já existentes.
Há um número considerável de projetos que não têm uma proposta clara e acabam sendo abandonados após um tempo de especulação.
Volatilidade e reputação
Bitcoin: embora o Bitcoin seja instável, ele é amplamente aceito como o padrão-ouro das moedas digitais.
Sua imagem foi construída ao longo de mais de dez anos de operação confiável e segurança comprovada.
Outras criptomoedas/shitcoins
Muitas shitcoins enfrentam alta volatilidade, frequentemente impulsionada por especulação ou manipulação de mercado.
A falta de clareza e as práticas duvidosas de alguns projetos prejudicam a imagem do setor como um todo.
Resistência à censura
Bitcoin: devido à sua descentralização e segurança, o Bitcoin é muito resistente à censura. Qualquer pessoa com acesso à internet pode participar da rede e fazer transações.
Outras criptomoedas/shitcoins
Muitas "shitcoins" dependem de estruturas centralizadas ou têm líderes identificáveis que podem ser pressionados por governos ou outros atores para censurar transações.
Resumindo, o Bitcoin continua sendo o líder indiscutível no mundo das moedas digitais devido à sua descentralização, segurança e escassez comprovada. Ele é um sistema feito para durar, oferecendo liberdade financeira e proteção contra a inflação.
Enquanto isso, muitas criptomoedas ou shitcoins não conseguem atingir os mesmos padrões de segurança e confiança, frequentemente priorizando velocidade, funções extras ou lucros especulativos rápidos. Para investidores e usuários, é importante distinguir entre o Bitcoin e os vários projetos alternativos, muitos dos quais podem não resistir ao teste do tempo.
O Bitcoin não só iniciou uma revolução financeira, mas continua sendo o padrão pelo qual todas as outras moedas digitais são medidas.

2025-06-17 15:40:23No sistema Bitcoin, a proteção e a posse dos fundos são asseguradas por um modelo criptográfico que usa chaves privadas e públicas. Esses componentes são fundamentais para a segurança digital, permitindo que os usuários administrem e protejam seus ativos de maneira descentralizada. Esse processo elimina a necessidade de intermediários, assegurando que somente o legítimo proprietário tenha acesso ao saldo vinculado a um endereço específico na blockchain ou timechain.
Chaves privadas e públicas são partes de um sistema de criptografia assimétrica, onde dois códigos distintos, mas matematicamente ligados, são utilizados para garantir a segurança e a veracidade das transações.
Chave Privada = É um código secreto, normalmente apresentado como uma longa sequência de números e letras.
Funciona como uma senha que dá ao proprietário o controle sobre os bitcoins ligados a um endereço específico.
Deve ser mantida em total sigilo, pois qualquer pessoa que a tenha pode movimentar os fundos correspondentes.
Chave Pública = É matematicamente derivada da chave privada, mas não permite que a chave privada seja descoberta.
Funciona como um endereço digital, semelhante a um número de conta bancária, podendo ser compartilhada livremente para receber pagamentos.
Serve para confirmar a autenticidade das assinaturas geradas com a chave privada.
Juntas, essas chaves asseguram que as transações sejam seguras e verificáveis, dispensando a necessidade de intermediários.
O funcionamento das chaves privadas e públicas baseia-se na criptografia de curva elíptica. Quando um usuário quer enviar bitcoins, ele usa sua chave privada para assinar digitalmente a transação. Essa assinatura é exclusiva para cada operação e demonstra que o remetente possui a chave privada relacionada ao endereço de envio.
Os nós da rede Bitcoin checam essa assinatura utilizando a chave pública correspondente, garantindo que:
A assinatura é válida.
A transação não foi alterada desde que foi assinada.
O remetente tem a propriedade legítima dos fundos.
Se a assinatura for aceita, a transação é registrada na blockchain ou timechain e se torna irreversível. Esse procedimento protege os fundos contra fraudes e gastos duplicados.
A segurança das chaves privadas é um dos pontos mais importantes do sistema Bitcoin. Perder essa chave significa perder permanentemente o acesso aos fundos, pois não há nenhuma autoridade central capaz de recuperá-la.
Boas práticas para proteger a chave privada incluem:
Armazenamento offline: longe de redes conectadas à internet, diminuindo o risco de ataques cibernéticos.
Carteiras de hardware: dispositivos físicos dedicados para armazenar chaves privadas de forma segura.
Backup e redundância: manter cópias de segurança em locais seguros e distintos.
Criptografia adicional: proteger arquivos digitais que contêm chaves privadas com senhas fortes e criptografia.
Ameaças comuns incluem:
Phishing e malware: ataques que tentam enganar os usuários para obter acesso às chaves.
Roubo físico: no caso de chaves guardadas em dispositivos físicos.
Perda de senhas e backups: que pode resultar na perda definitiva dos fundos.
O uso de chaves privadas e públicas dá ao proprietário controle total sobre seus fundos, eliminando intermediários como bancos ou governos. Esse modelo coloca a responsabilidade de proteção nas mãos do usuário, o que representa tanto liberdade quanto risco.
Diferente de sistemas financeiros tradicionais, onde instituições podem reverter transações ou congelar contas, no sistema Bitcoin, a posse da chave privada é a única prova de propriedade. Esse princípio é frequentemente resumido pela frase: "Not your keys, not your coins" (Se não são suas chaves, não são suas moedas).
Essa abordagem fortalece a soberania financeira, permitindo que indivíduos guardem e movam valor de maneira independente e sem censura.
Apesar de sua segurança, o sistema de chaves também apresenta riscos. Se uma chave privada for perdida ou esquecida, não existe como recuperar os fundos associados. Isso já levou à perda de milhões de bitcoins ao longo dos anos.
Para reduzir esse risco, muitos usuários utilizam frases-semente (seed phrases), que são uma lista de palavras usadas para restaurar carteiras e chaves privadas. Essas frases devem ser guardadas com o mesmo cuidado, pois também podem ser usadas para acessar os fundos.
Resumindo, as chaves privadas e públicas são a base da segurança e da propriedade no sistema Bitcoin. Elas asseguram que somente os verdadeiros proprietários possam mover seus fundos, promovendo um sistema financeiro descentralizado, seguro e resistente à censura.
No entanto, essa liberdade acarreta grandes responsabilidades, exigindo que os usuários adotem práticas severas para proteger suas chaves privadas. A perda ou comprometimento dessas chaves pode levar a consequências irreversíveis, ressaltando a importância de educação e preparação ao usar o sistema Bitcoin.
Assim, o modelo de chaves criptográficas não apenas melhora a segurança, mas também representa a essência da independência financeira proporcionada pelo Bitcoin.

2025-06-17 15:37:47A rede Bitcoin é formada por uma infraestrutura descentralizada feita de dispositivos chamados nós. Esses nós têm um papel crucial na validação, verificação e manutenção do sistema, assegurando a segurança e a integridade do blockchain ou timechain. Ao contrário dos sistemas tradicionais, onde uma autoridade central controla as operações, a rede Bitcoin requer a colaboração de milhares de nós pelo mundo, promovendo descentralização e transparência.
Na rede Bitcoin, um nó é qualquer computador que está conectado ao sistema e participa do armazenamento, validação ou distribuição de informações. Esses dispositivos rodam o software do Bitcoin e podem operar em diferentes níveis de participação, desde tarefas básicas de transmissão de dados até a validação total de transações e blocos.
Existem dois tipos principais de nós:
Nós completos (full nodes):
Armazenam uma cópia total do blockchain ou timechain.
Validam e verificam todas as transações e blocos de acordo com as regras do protocolo.
Asseguram a segurança da rede ao rejeitar transações inválidas ou tentativas de fraude.
Nós leves (light nodes):
Armazenam somente partes do blockchain ou timechain, não a estrutura inteira.
Confiam em nós completos para obter dados sobre o histórico de transações.
São mais rápidos e menos exigentes em termos de recursos, mas dependem de terceiros para validação completa.
Os nós conferem se as transações enviadas seguem as regras do protocolo, como assinaturas digitais válidas e ausência de gastos duplos.
Somente transações válidas são enviadas para outros nós e incluídas no próximo bloco.
Os nós completos mantêm uma cópia atualizada de todo o histórico de transações da rede, garantindo integridade e transparência e se houver discrepâncias, os nós seguem a cadeia mais longa e válida, evitando manipulações.
Os nós transmitem informações de transações e blocos para outros nós na rede. Esse processo assegura que todos os participantes estejam sincronizados e atualizados.
Como a rede Bitcoin é composta por milhares de nós independentes, é quase impossível que um único agente controle ou modifique o sistema.
Os nós também protegem contra ataques ao validar informações e barrar tentativas de fraudes.
Os nós completos são muito importantes, pois atuam como auditores independentes. Eles não precisam de terceiros e podem verificar todo o histórico de transações diretamente.
Ao manterem uma cópia completa do blockchain ou timechain, esses nós permitem que qualquer pessoa valide transações sem depender de intermediários, promovendo clareza e liberdade financeira.
Além disso, os nós completos:
Reforçam a resistência à censura: Nenhum governo ou entidade pode excluir ou alterar dados registrados no sistema.
Preservam a descentralização: Quanto mais nós completos existirem, mais segura e forte será a rede.
Aumentam a confiança no sistema: Os usuários podem confirmar de forma independente se as regras estão sendo seguidas.
Apesar de seu valor, operar um nó completo pode ser difícil, pois exige espaço de armazenamento, processamento e largura de banda. À medida que o blockchain ou timechain cresce, os requisitos técnicos aumentam, o que pode dificultar a participação de usuários comuns.
Para resolver esse problema, a comunidade busca sempre soluções, como melhorias no software e aumento na escalabilidade, para facilitar o acesso à rede sem prejudicar a segurança.
Resumindo, os nós são a base da rede Bitcoin, desempenhando funções importantes na validação, verificação e distribuição de transações. Eles garantem a descentralização e a segurança do sistema, permitindo que os participantes operem de forma confiável sem depender de intermediários.
Particularmente, os nós completos têm um papel crucial na proteção da integridade do blockchain ou timechain, tornando a rede Bitcoin resistente a censura e manipulação.
Embora operar um nó possa exigir recursos técnicos, seu efeito na preservação da liberdade financeira e na confiança do sistema é inestimável. Assim, os nós continuam sendo elementos essenciais para o sucesso e a durabilidade do Bitcoin.

2025-06-17 15:13:26O blockchain ou timechain é uma tecnologia nova que mudou a maneira como dados e transações são registrados e armazenados. Sua estrutura descentralizada e muito segura proporciona transparência e confiança, tornando-o um sistema amplamente utilizado para operações digitais. Essa tecnologia é importante para a criação de sistemas financeiros e registros digitais que não podem ser alterados.
O que é o blockchain ou timechain?
O blockchain ou timechain é basicamente um livro-razão digital que é distribuído, projetado para registrar transações de forma sequencial e inalterável. Ele é composto por blocos ligados em uma cadeia, cada um contendo um conjunto de informações, como transações, marcas de tempo (timestamp) e um identificador único chamado hash.
Esses blocos estão organizados em ordem cronológica, o que garante a integridade dos registros ao longo do tempo. O termo timechain, usado como sinônimo, enfatiza essa característica temporal do sistema, onde cada bloco é ligado ao anterior, formando uma cadeia de eventos que não pode ser manipulada.
A validação dos blocos no blockchain ou timechain é realizada por meio de um processo chamado mineração. Os participantes da rede, conhecidos como mineradores, utilizam computadores potentes para resolver problemas matemáticos complexos. Esse processo, chamado de prova de trabalho, é necessário para validar as transações e adicionar um novo bloco à cadeia.
Cada bloco contém:
Transações verificadas - Um conjunto de operações aprovadas pela rede.
Hash do bloco anterior - Um código único que conecta o novo bloco ao anterior, garantindo a continuidade e a segurança.
Nonce - Um número utilizado no processo de mineração para gerar o hash do bloco.
Uma vez que um bloco é validado, ele é adicionado permanentemente ao blockchain ou timechain, e todos os nós (computadores participantes) na rede atualizam suas cópias desse livro-razão.
Um dos principais benefícios do blockchain ou timechain é a segurança oferecida por seu modelo descentralizado. Ao contrário de sistemas tradicionais que dependem de servidores centrais, ele distribui seus dados entre milhares de computadores em todo o mundo.
A imutabilidade é garantida pelo uso de criptografia e pela estrutura encadeada dos blocos. Qualquer tentativa de alterar um bloco exigiria modificar todos os blocos que vêm depois, o que seria praticamente impossível devido ao alto poder computacional necessário.
Além disso, o uso de algoritmos criptográficos torna o sistema resistente a fraudes e manipulações. Esse modelo proporciona confiança, mesmo em ambientes sem intermediários ou autoridades centrais.
O blockchain ou timechain é transparente, porque qualquer pessoa pode acessar o histórico completo das transações registradas na rede. Isso cria um sistema que pode ser auditado e confiável.
No entanto, a privacidade dos participantes é protegida, pois as transações são registradas por meio de endereços digitais anônimos, sem revelar identidades pessoais. Esse equilíbrio entre transparência e privacidade torna o sistema seguro e flexível.
O uso do blockchain ou timechain vai além das transações financeiras. Ele é útil em áreas como contratos inteligentes, registro de bens, cadeia de suprimentos e votação online. Sua capacidade de criar registros permanentes e verificáveis permite soluções novas em várias indústrias.
Por exemplo, em sistemas de rastreamento de produtos, o blockchain ou timechain assegura a veracidade dos dados, anotando cada fase do processo de produção e distribuição. Isso diminui fraudes e aumenta a eficiência operacional.
Vantagens e DesafiosEntre as principais vantagens do blockchain ou timechain, podem ser destacadas:Descentralização: Eliminação de intermediários, reduzindo custos e aumentando a eficiência.
Segurança - Proteção contra fraudes e ataques digitais.
Transparência - Registro público e verificável de todas as transações.
Imutabilidade - Garantia de que os dados não podem ser modificados após serem registrados.
No entanto, desafios ainda precisam ser enfrentados, como a escalabilidade, pois o crescimento contínuo da rede pode necessitar de maior capacidade de armazenamento e processamento. Além disso, questões regulatórias e a adoção em larga escala requerem melhorias contínuas.
Resumindo, o blockchain ou timechain é uma tecnologia inovadora que muda a maneira como dados e transações são armazenados, assegurando segurança, transparência e eficiência. Sua descentralização elimina a dependência de intermediários, tornando-o um sistema confiável e resistente a manipulações.
Apesar dos desafios técnicos e regulatórios, o blockchain ou timechain continua a se desenvolver, demonstrando seu potencial em várias áreas além do setor financeiro. Sua promessa de transparência e imutabilidade já está moldando o futuro dos sistemas digitais, firmando-se como uma base essencial para a economia moderna e para a confiança digital.

2025-06-17 15:10:22Nos últimos anos, o Bitcoin tem sido frequentemente comparado ao ouro, ganhando o nome de "ouro digital". Essa comparação ocorre porque ambas as formas de valor têm características em comum, como escassez, durabilidade e aceitação mundial. Contudo, o Bitcoin também representa uma novidade tecnológica que muda a ideia de dinheiro e investimento, se destacando como uma alternativa moderna e eficaz ao ouro físico.
Uma das razões pelas quais o Bitcoin é comparado ao ouro é a sua escassez programada. Enquanto o ouro é um recurso natural limitado, cuja oferta depende da mineração, o Bitcoin tem um teto máximo de 21 milhões de unidades, definido em seu código. Esse teto faz com que o Bitcoin seja protegido contra a inflação, ao contrário das moedas tradicionais, que podem ser criadas sem limites pelos bancos centrais.
Essa característica traz um valor duradouro, parecido com o ouro, já que a oferta limitada ajuda a manter o poder de compra ao longo do tempo. Com o aumento da procura por Bitcoin, sua quantidade reduzida reforça seu papel como reserva de valor.
Outro aspecto que aproxima o Bitcoin do ouro é a durabilidade. Enquanto o ouro resiste à corrosão e pode ser guardado por séculos, o Bitcoin é um ativo digital protegido por criptografia avançada e armazenado na blockchain — um livro-razão imutável e descentralizado.
Além disso, o Bitcoin é mais fácil de transportar do que o ouro. Mover ouro físico envolve custos e segurança, tornando o transporte complicado, principalmente em transações internacionais. Por outro lado, o Bitcoin pode ser enviado digitalmente para qualquer parte do mundo em minutos, com taxas baixas e sem intermediários. Essa vantagem tecnológica torna o Bitcoin mais eficaz para um mundo globalizado e digital.
A segurança é outra característica que o Bitcoin e o ouro têm em comum. O ouro é difícil de falsificar, fazendo dele uma reserva de valor confiável. Da mesma forma, o Bitcoin usa protocolos de criptografia que asseguram transações seguras e protegidas contra fraudes.
Além disso, todas as transações feitas com Bitcoin são registradas na blockchain, fornecendo um nível de transparência que o ouro físico não oferece. Qualquer pessoa pode revisar as transações na rede, aumentando a confiança e a rastreabilidade.
EconômicaHistoricamente, o ouro tem sido utilizado como proteção contra a inflação e crises econômicas. Durante momentos de instabilidade, os investidores buscam o ouro como uma maneira de preservar seu patrimônio. O Bitcoin, por sua vez, está surgindo como uma alternativa digital com o mesmo propósito.
Em países com alta inflação ou instabilidade política, o Bitcoin tem sido usado como uma proteção contra a desvalorização das moedas locais. Sua natureza descentralizada impede que governos confisquem ou controlem diretamente o ativo, garantindo maior liberdade financeira para os usuários.
Apesar de suas semelhanças com o ouro, o Bitcoin ainda enfrenta desafios. Sua volatilidade é muito maior, o que pode causar incertezas a curto prazo. No entanto, muitos especialistas afirmam que essa volatilidade é uma característica comum em ativos novos e tende a diminuir com o tempo, à medida que a aceitação cresce e o mercado se desenvolve.
Outro desafio é a regulamentação. Enquanto o ouro já é reconhecido globalmente como um ativo financeiro, o Bitcoin ainda enfrenta resistência de governos e instituições financeiras, que procuram formas de controlá-lo e regulá-lo.
Resumindo, o Bitcoin, muitas vezes chamado de "ouro digital", oferece uma nova forma de valor que combina as melhores características do ouro com a eficiência e a inovação da tecnologia digital. Sua escassez planejada, segurança criptográfica, portabilidade e resistência à censura fazem dele uma alternativa viável para preservar riqueza e realizar transações no mundo moderno.
Mesmo com muita volatilidade, o Bitcoin está se firmando como uma reserva de valor e como um ativo de proteção contra crises econômicas. Assim, ele representa não apenas uma evolução do sistema financeiro, mas também um símbolo da mudança para uma economia digital descentralizada e global.

2025-06-17 15:07:03O surgimento do Bitcoin trouxe uma nova visão para o conceito de dinheiro, desafiando o sistema financeiro convencional baseado em moedas fiduciárias. Enquanto as moedas fiduciárias, como o real, o dólar e o euro, são amplamente usadas e reconhecidas como métodos de troca, o Bitcoin representa uma inovação digital que propõe descentralização e autonomia financeira. Embora ambos desempenhem funções básicas como meio de troca e reserva de valor, suas diferenças principais estão na maneira como são emitidos, geridos e transacionados.
Uma das principais distinções entre o Bitcoin e as moedas fiduciárias é a maneira como são emitidos e administrados. As moedas fiduciárias são emitidas por bancos centrais, que têm o poder de regular sua quantidade em circulação. Esse modelo permite a aplicação de políticas monetárias, como o aumento da oferta de dinheiro para estimular a economia ou a diminuição para controlar a inflação. No entanto, essa capacidade também pode resultar na desvalorização da moeda, se for emitida em excesso.
O Bitcoin, por outro lado, tem um sistema de emissão totalmente descentralizado. Ele é criado por meio de um processo chamado mineração, no qual computadores resolvem problemas matemáticos complexos para validar transações na rede. Além disso, a oferta total de bitcoins é limitada a 21 milhões de unidades, tornando-o um ativo deflacionário, ou seja, sua escassez pode aumentar seu valor ao longo do tempo. Essa limitação contrasta fortemente com a natureza ilimitada da impressão de moedas fiduciárias.
Moedas fiduciárias são centralizadas, o que significa que sua emissão e controle são decididos por autoridades governamentais. Isso também implica que transações feitas com essas moedas passam por intermediários, como bancos, que podem aplicar taxas e limites, além de estarem sujeitos a regulamentações e auditorias.
O Bitcoin, por sua vez, é descentralizado. Ele opera em uma rede peer-to-peer, onde as transações são verificadas por participantes chamados mineradores e registradas em um livro público conhecido como blockchain. Essa descentralização elimina a necessidade de intermediários, tornando o Bitcoin mais resistente à censura e ao controle governamental. Isso também proporciona maior transparência, já que qualquer pessoa pode verificar as transações na rede.
Outra diferença importante está na maneira como as transações são feitas. Com moedas fiduciárias, as transações geralmente dependem de bancos ou sistemas de pagamento, que podem impor restrições de horários e taxas altas, especialmente para transferências internacionais.
O Bitcoin, por outro lado, permite transferências diretas entre pessoas, em qualquer lugar do mundo e a qualquer momento, sem a necessidade de intermediários. Isso torna o sistema mais acessível, especialmente para aqueles que não possuem contas bancárias ou vivem em países com sistemas financeiros restritivos. Além disso, as taxas de transação do Bitcoin podem ser menores do que as taxas cobradas por bancos tradicionais.
As moedas fiduciárias proporcionam segurança baseada em leis governamentais e no sistema bancário, mas os usuários precisam confiar nesses intermediários. O Bitcoin, em contrapartida, oferece um alto nível de segurança através de criptografia avançada. As carteiras digitais, que guardam bitcoins, são protegidas por chaves privadas, assegurando que somente o dono possa acessá-las.
No entanto, a privacidade funciona de maneira diferente. Transações em moedas fiduciárias normalmente estão ligadas à identidade do usuário, enquanto o Bitcoin oferece um certo nível de anonimato, já que os endereços das carteiras não requerem identificação pessoal. Ainda assim, todas as transações são públicas e registradas no blockchain, o que pode ser um ponto de monitoramento para autoridades.
O valor das moedas fiduciárias é sustentado pela confiança no governo que as emite e na economia do país. Por outro lado, o Bitcoin não é apoiado por nenhum governo ou ativo físico. Seu valor é definido pela oferta e demanda no mercado, fazendo com que seja altamente volátil. Embora essa volatilidade apresente um risco, também atrai pessoas que veem o Bitcoin como uma possibilidade de valorização a longo prazo.
Resumindo, o Bitcoin e as moedas fiduciárias diferem significativamente em sua estrutura, controle e funcionalidade. Enquanto as moedas fiduciárias são controladas por governos e dependem de intermediários, o Bitcoin oferece descentralização, transparência e liberdade financeira. Apesar de sua volatilidade e alguns desafios relacionados à regulamentação, o Bitcoin representa uma alternativa nova ao sistema financeiro tradicional.

2025-06-17 15:02:39O Bitcoin foi criado como algo muito além de uma moeda digital; ele é uma ideia inovadora que questiona os fundamentos do sistema financeiro convencional. A ideia por trás de sua criação, apresentada pelo enigmático Satoshi Nakamoto, se concentra em dois princípios principais: descentralização e liberdade financeira. Essas noções refletem um esforço para devolver o controle do dinheiro às pessoas, eliminando intermediários e diminuindo a influência de governos e grandes instituições financeiras.
A descentralização é a base do Bitcoin. Diferente das moedas comuns, que são emitidas e geridas por bancos centrais e governos, o Bitcoin funciona em uma rede peer-to-peer. Isso quer dizer que não existe uma autoridade central ou entidade única que controla a moeda. Ao invés disso, todas as transações são validadas e registradas em um livro-razão público chamado blockchain ou timechain, mantido por milhares de computadores em várias partes do mundo.
Essa estrutura descentralizada garante que o Bitcoin seja resistente à censura e imune a manipulações de políticas monetárias, como a impressão excessiva de dinheiro, que pode causar inflação. Além disso, ela elimina a necessidade de intermediários, como bancos, permitindo transações diretas entre usuários. Isso é especialmente valioso em cenários onde o sistema bancário tradicional é inacessível ou composto, como em áreas remotas ou países em crise econômica.
A liberdade financeira promovida pelo Bitcoin é outro elemento transformador. Em sistemas tradicionais, os indivíduos dependem de terceiros, como bancos ou instituições financeiras, para acessar, guardar e transferir dinheiro. Essas entidades podem impor restrições, como limites de saque, altas taxas de transferência ou até mesmo bloquear contas. Com o Bitcoin, o usuário possui controle total sobre seus fundos através de chaves privadas (uma espécie de senha que possibilita o acesso à sua carteira digital).
Além disso, o Bitcoin oferece uma solução acessível para bilhões de pessoas no mundo que estão fora do sistema bancário. Segundo dados do Banco Mundial, cerca de 1,4 bilhão de adultos não têm acesso a contas bancárias, mas muitos têm acesso à internet ou a smartphones. O Bitcoin permite que essas pessoas participem da economia global sem a necessidade de instituições intermediárias.
Outro ponto importante é a resistência à censura. Em regimes autoritários ou situações de instabilidade política, governos podem confiscar ou bloquear os bens dos cidadãos. O Bitcoin, por ser descentralizado e operar em uma rede global, não pode ser controlado ou confiscado de maneira arbitrária, oferecendo uma camada extra de proteção financeira para indivíduos em situações de risco.
A visão do Bitcoin também abrange a formação de um sistema financeiro mais justo e transparente. O blockchain ou timechain, ao registrar todas as transações de modo público e imutável, diminui a chance de fraudes e corrupção. Além disso, a quantidade limitada de 21 milhões de bitcoins, programada no código da moeda, favorece um modelo deflacionário que contrasta com a expansão ilimitada de moedas fiduciárias. Isso confere ao Bitcoin a capacidade de ser uma reserva de valor estável no longo prazo.
Apesar de sua visão promissora, o caminho para alcançar completamente essa liberdade financeira não é livre de desafios. A volatilidade do preço do Bitcoin, preocupações regulatórias e barreiras tecnológicas ainda são obstáculos a serem superados. No entanto, essas dificuldades também criam oportunidades para inovação e para o fortalecimento do ecossistema ao longo do tempo.
Resumindo, a visão por trás do Bitcoin representa uma interrupção do sistema financeiro centralizado, oferecendo às pessoas mais autonomia, transparência e segurança sobre seus recursos financeiros. Ele não é apenas uma tecnologia, mas um movimento que busca empoderar os indivíduos, especialmente aqueles excluídos ou prejudicados pelos modelos econômicos tradicionais. Ao promover descentralização e liberdade financeira, o Bitcoin abre caminho para um futuro onde o dinheiro realmente pertence às pessoas, e não às instituições.

2025-06-17 15:01:45Bank run on every crypto bank then bank run on every "real" bank.
— ODELL (@ODELL) December 14, 2022
Good morning.
It looks like PacWest will fail today. It will be both the fifth largest bank failure in US history and the sixth major bank to fail this year. It will likely get purchased by one of the big four banks in a government orchestrated sale.
March 8th - Silvergate Bank
March 10th - Silicon Valley Bank
March 12th - Signature Bank
March 19th - Credit Suisse
May 1st - First Republic Bank
May 4th - PacWest Bank?PacWest is the first of many small regional banks that will go under this year. Most will get bought by the big four in gov orchestrated sales. This has been the playbook since 2008. Follow the incentives. Massive consolidation across the banking industry. PacWest gonna be a drop in the bucket compared to what comes next.
First, a hastened government led bank consolidation, then a public/private partnership with the remaining large banks to launch a surveilled and controlled digital currency network. We will be told it is more convenient. We will be told it is safer. We will be told it will prevent future bank runs. All of that is marketing bullshit. The goal is greater control of money. The ability to choose how we spend it and how we save it. If you control the money - you control the people that use it.
If you found this post helpful support my work with bitcoin.

2025-06-17 18:00:27Quando se fala em Bitcoin, é comum chama-lo de moeda digital ou "investimento especulativo". No entanto, uma das funções mais fundamentais e menos compreendidas do Bitcoin é a sua função como rede de liquidação. Para entender isso, vale compará-lo com os sistemas tradicionais de liquidação, como o SWIFT, e explorar como o Bitcoin oferece uma camada base de transferência de valor global, descentralizada e resistente à censura.
Antes de mais, explico a diferença entre liquidez e liquidação:
Liquidez refere-se à facilidade de converter um ativo em “dinheiro” sem perda de valor.
Liquidação é o processo de concluir uma transação (transferência real de valor entre partes).
SWIFT: a camada de comunicação do sistema financeiro tradicional
O sistema SWIFT (Society for Worldwide Interbank Financial Telecommunication) é uma rede de comunicação entre bancos. Ele não movimenta dinheiro diretamente, mas envia mensagens padronizadas que instruem as instituições financeiras a realizarem transferências. O processo envolve diversos intermediários, é custoso, lento (podendo levar dias) e depende de confiança entre as partes e regulações locais.
Diferente do SWIFT, o Bitcoin é uma rede autossuficiente que permite a liquidação direta de valores entre duas partes, sem necessidade de intermediários. A cada bloco minerado, transações são validadas e registradas de forma imutável em uma base de dados global, transparente e segura: a blockchain.
Liquidação final: Assim que uma transação é confirmada por um número suficiente de blocos, ela é considerada final e irreversível.
Resistência à censura: Não há entidade central que possa impedir ou reverter uma transação válida.
Disponibilidade global: A rede está acessível 24 horas por dia, 7 dias por semana, em qualquer lugar do mundo com acesso à internet.
Assim como o ouro já serviu como base para sistemas monetários, o Bitcoin está se consolidando como uma camada base de valor digital. Essa base pode dar suporte a outras camadas, como:
Lightning Network, que permite transações quase instantâneas e com baixíssimas taxas;
Serviços financeiros tokenizados, que podem usar o Bitcoin como colateral ou meio de liquidação entre instituições.
Ao funcionar como uma rede de liquidação pública e neutra, o Bitcoin oferece uma alternativa ao sistema tradicional, que é fragmentado, fechado e baseado em confiança entre instituições.
Resumindo, mais do que um ativo especulativo, o Bitcoin está emergindo como uma infraestrutura financeira global. Como rede de liquidação, ele elimina intermediários, reduz custos, aumenta a segurança e democratiza o acesso à transferência de valor. Num mundo cada vez mais interconectado e digitalizado, compreender o papel do Bitcoin como camada base pode ser essencial para entender o futuro do dinheiro.

2025-06-17 15:01:04This article was originally published on dev.to by satshacker.
Alright, you’ve built a useful and beautiful website, tool or app. However, monetization isn’t a priority and you’d rather keep the project free, ads-free and accessible?
Accepting donations would be an option, but how? A PayPal button? Stripe? Buymeacoffe? Patreon?
All of these services require a bank account and KYC verification, before you can send and receive donations – not very convenient.
If we only could send value over the internet, with just one click and without the need of a bank account…
Oh, hold on, that’s bitcoin. The decentralized protocol to send value across the globe. Money over TCP/IP.
In this article, we’ll learn how anyone can easily add a payment button or donation widget on a website or app.
Let’s get into it.
Introduction
Bitcoin is digital money that you can send and receive without the need for banks. While bitcoin is extremely secure, it’s not very fast. The maximum transactions per second (TPS) the network can handle is about 7. Obviously that’s not useful for daily payments or microtransactions.
If you’d like to dig deeper into how bitcoin works, a great read is “Mastering Bitcoin” by Andreas Antonopoulos.
Bitcoin vs Lightning
If you’d like to receive bitcoin donations “on-chain” all you need is a bitcoin wallet. You simply display your bitcoin address on your site and that’s it. You can receive donations.
It would look something like this; 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa
Instead of showing the actual bitcoin address, you can also turn it into a QR code.
However, this is not a recommended solution. Using static on-chain addresses has two major downsides. It lowers privacy for you and your donnors and it’s a UTXO disaster because many small incoming transactions could beocme hard to consolidate in the future.
For donations and small transactions, the Lightning Network is the better option. Lightning allows for instant settlement with fees only a fraction of a cent.
Similar to bitcoin, you have the choice between non-custodial and custodial wallets. This means, either you have full control over your money or the wallet provider has.
Option 1: Lightning Address
With the lightning address feature, you an easily receive donations to an email like address.
It looks like this: yourname@wallet.com
Many wallets support lightning addresses and make it easy to create one. Then, you simple add the address to your donation page and you’re ready to receive tips.
You can also add a link link as in lightning:yourname@wallet.com and compatible lightning wallets and browser wallets will detect the address.
Option 2: Lightning Donation Widgets
If you like to take it a step further, you can also create a more enhanced donation checkout flow. Of course you could programm something yourself, there are many open source libraries you can build upon. If you want a simple plug-and-play solution, here are a couple of options:
Name
Type
Registration
SatSale
Self-hosted
No KYC
BTCPay Server
Self-hosted
No KYC
Pay With Flash
Widget
Email

2025-06-17 17:58:15Bitcoin, desde o seu surgimento em 2009, tem gerado uma variedade de histórias de sucesso e fracasso. Algumas dessas histórias são de pessoas que investiram cedo na criptomoeda e colheram os frutos de sua visão precoce, enquanto outras refletem os altos e baixos que caracterizam o mercado altamente volátil de Bitcoin. Ao longo dos anos, muitas dessas histórias tornaram-se emblemáticas, servindo tanto de inspiração quanto de alerta para quem entra nesse mercado.
Histórias de sucesso
O caso de Laszlo Hanyecz – A pizza de 10.000 Bitcoins Uma das histórias mais icônicas e, ao mesmo tempo, um exemplo do potencial e da volatilidade do Bitcoin, envolve Laszlo Hanyecz, um programador americano. Em 2010, Hanyecz pagou 10.000 bitcoins por duas pizzas. Na época, o valor das criptomoedas era tão baixo que essa transação passou despercebida, mas, em retrospectiva, os 10.000 bitcoins pagos por uma simples refeição valeriam centenas de milhões de dólares nos anos seguintes, quando o preço do Bitcoin disparou.
Essa história, muitas vezes citada, é um lembrete da enorme valorização do Bitcoin desde os seus primeiros dias. Embora Hanyecz não tenha ficado rico com essa transação, a história da "pizza de 10.000 bitcoins" tornou-se uma metáfora para o crescimento do Bitcoin, mostrando como uma pequena quantidade da moeda no início poderia ter mudado a vida de alguém para sempre.
O caso de Michael Saylor e a MicroStrategy no presente Michael Saylor, CEO da MicroStrategy, é outro exemplo de sucesso no mundo do Bitcoin. Em 2020, Saylor decidiu transformar a sua empresa numa das primeiras grandes corporações a investir pesadamente em Bitcoin, comprando mais de 100.000 bitcoins. A decisão foi inicialmente vista com ceticismo, mas ao longo do tempo, o preço do Bitcoin subiu consideravelmente, fazendo com que o investimento de Saylor se tornasse extremamente lucrativo. Para ele, o Bitcoin não era apenas um investimento especulativo, mas uma maneira de proteger a sua empresa da inflação e da desvalorização da moeda fiduciária.
Este caso é um exemplo de como uma aposta estratégica em Bitcoin pode resultar em grandes lucros para quem tem visão de longo prazo e confiança no potencial do ativo. A MicroStrategy tornou-se um dos maiores detentores de Bitcoin no mundo corporativo, e Saylor ganhou reconhecimento por ser um defensor do Bitcoin no mundo empresarial.
Histórias de fracasso
O caso de James Howells – O desaparecimento de 8.000 Bitcoins James Howells, um ex-empregado de TI de Gales, é um exemplo clássico de como a volatilidade e a negligência podem resultar em grandes perdas. Em 2013, Howells, que estava a minerar Bitcoin em casa, acumulou 8.000 bitcoins, que valiam cerca de 5.000 libras na época. Quando o mercado estava em queda, ele decidiu limpar o seu computador antigo e jogá-lo fora, sem perceber que os bitcoins estavam guardados em uma carteira digital nesse dispositivo.
Após a ascensão do preço do Bitcoin, Howells tentou recuperar o disco rígido, que estava enterrado numa lixeira em um aterro sanitário. Apesar das tentativas de convencer a cidade a permitir a escavação do aterro, o pedido foi negado, e ele nunca conseguiu recuperar os bitcoins. Este caso é um lembrete de como, sem a devida segurança e cuidado, até mesmo grandes fortunas podem ser perdidas no mundo das criptomoedas.
O colapso da Mt. Gox – A maior exchange de Bitcoin da história Uma das maiores histórias de fracasso envolvendo Bitcoin está relacionada à exchange Mt. Gox, uma plataforma de negociação de Bitcoin que, em 2014, faliu após alegadamente perder cerca de 850.000 bitcoins dos seus clientes, num valor superior a 450 milhões de dólares na época. A Mt. Gox foi, por um período, a maior exchange de Bitcoin do mundo, mas a sua falência foi um marco negativo na história do Bitcoin.
A falência da Mt. Gox foi causada por uma combinação de hacking, erros internos de segurança e má gestão. Embora alguns dos bitcoins perdidos tenham sido recuperados mais tarde, muitos investidores ficaram devastados pela perda dos seus fundos. Este incidente trouxe à tona a importância da segurança nas exchanges de Bitcoin e da responsabilidade das plataformas financeiras no manejo das criptomoedas de seus clientes.
O impacto da volatilidade e da adoção no mercado
As histórias de sucesso e fracasso envolvendo Bitcoin não são apenas anedotas, mas refletem a natureza imprevisível e arriscada do mercado de criptomoedas. O preço de Bitcoin pode flutuar drasticamente, o que significa que investidores podem tanto fazer grandes fortunas quanto sofrer grandes perdas. Enquanto alguns vêem Bitcoin como uma forma de alcançar a liberdade financeira e proteger-se contra a inflação, outros enfrentam o risco de perder tudo, como demonstrado pelos casos de fracasso.
A adoção crescente de Bitcoin em mercados emergentes, bem como a entrada de investidores institucionais, como a MicroStrategy e o próprio Elon Musk, são indicativos de que o Bitcoin está a ser cada vez mais reconhecido como uma alternativa legítima ao sistema financeiro tradicional. No entanto, as falências de exchanges e as perdas de grandes quantidades de Bitcoin destacam a necessidade de uma abordagem prudente e de uma infraestrutura mais robusta para garantir a segurança e a confiança dos utilizadores.
Resumindo, as histórias de sucesso e fracasso em torno do Bitcoin são um reflexo da natureza volátil e emergente desta moeda digital. Enquanto alguns ganharam milhões, outros perderam fortunas devido à falta de precaução, erros de gestão ou simplesmente pelo preço imprevisível da criptomoeda. Através destas histórias, fica claro que, embora o Bitcoin tenha o potencial de gerar grandes recompensas, ele também apresenta riscos significativos. Para aqueles que entram nesse mercado, é crucial estar preparado e consciente dos desafios que podem surgir, garantindo segurança e adotando uma estratégia de longo prazo para lidar com as incertezas e volatilidade do mercado.

2025-06-17 17:56:33Bitcoin, desde o seu lançamento em 2009, tem atraído a atenção de diversos investidores e visionários que acreditam no seu potencial para revolucionar o sistema financeiro global. Ao longo dos anos, várias figuras se destacaram no movimento em torno da criptomoeda, seja como pioneiros que ajudaram a fundá-la, ou como investidores que apostaram no seu futuro. Estes indivíduos desempenharam papéis cruciais no desenvolvimento do Bitcoin, na sua adoção crescente e na sua legitimação no mercado financeiro.
Satoshi Nakamoto
O maior pioneiro do Bitcoin é, sem dúvida, o seu criador, Satoshi Nakamoto. Embora o nome seja um pseudónimo, a sua contribuição para a criação e lançamento do Bitcoin foi fundamental. Em 2008, Nakamoto publicou o famoso whitepaper intitulado "Bitcoin: A Peer-to-Peer Electronic Cash System", detalhando a ideia de uma moeda digital descentralizada que poderia operar sem a necessidade de uma autoridade central, como um banco. Em 2009, ele lançou o software Bitcoin e minerou o primeiro bloco da blockchain, conhecido como "bloco gênese".
Satoshi Nakamoto permaneceu uma figura misteriosa, nunca revelando a sua verdadeira identidade. Ele foi responsável pelo desenvolvimento inicial do protocolo, mas desapareceu gradualmente da cena pública por volta de 2011, deixando o projeto nas mãos de uma comunidade crescente de desenvolvedores. A sua identidade permanece desconhecida até hoje, mas o seu impacto na criação de uma nova era digital é inegável.
Hal Finney
Hal Finney foi um dos primeiros colaboradores de Nakamoto e é amplamente reconhecido como o primeiro a receber uma transação de Bitcoin. Em janeiro de 2009, Finney recebeu 10 bitcoins de Nakamoto como parte de um teste de transação, tornando-se uma das primeiras pessoas a acreditar no projeto. Finney, que era um programador e investigador de segurança, desempenhou um papel importante no desenvolvimento técnico do Bitcoin e ajudou a popularizá-lo nas suas primeiras fases.
Finney foi uma figura respeitada na comunidade de criptografia e um defensor do movimento de descentralização digital. Ele continuou a apoiar o Bitcoin até sua morte, em 2014, e é lembrado como um dos maiores pioneiros da moeda digital.
Roger Ver
Roger Ver, conhecido como o "Bitcoin Jesus", foi um dos primeiros investidores e “evangelistas” do Bitcoin. Ver ficou fascinado com o conceito de uma moeda descentralizada e investiu cedo em vários projetos relacionados ao Bitcoin. Ele foi um dos primeiros a reconhecer o potencial disruptivo do Bitcoin, defendendo a sua adoção global e promovendo o seu uso como meio de pagamento.
Ver também foi uma das figuras centrais na criação de empresas e iniciativas que ajudaram a impulsionar o ecossistema Bitcoin. Embora tenha sido uma figura polêmica, devido às suas opiniões fortes sobre a escalabilidade do Bitcoin, e tenha se afastado da blockchain original do Bitcoin em favor do Bitcoin Cash, sua contribuição para a popularização da moeda é inegável.
Tim Draper
Tim Draper é um dos investidores mais conhecidos no espaço do Bitcoin e um defensor da sua adoção em larga escala. Em 2014, Draper comprou quase 30.000 bitcoins, que foram apreendidos pelo governo dos Estados Unidos em uma operação contra o mercado Silk Road. Draper fez essa compra por cerca de 19 milhões de dólares, e ele tem sido uma figura-chave na promoção do Bitcoin como uma alternativa viável às moedas fiduciárias.
Draper, um investidor de risco de renome e fundador da Draper Associates, é conhecido por sua visão de longo prazo e pela sua confiança na ascensão das criptomoedas. Ele tem defendido o Bitcoin como uma ferramenta para democratizar o acesso ao dinheiro e acredita que a adoção do Bitcoin vai crescer exponencialmente nos próximos anos.
Michael Saylor
Michael Saylor, CEO da MicroStrategy, é uma figura importante na adoção institucional do Bitcoin. Em 2020, Saylor fez uma aposta significativa ao comprar mais de 100.000 bitcoins para a sua empresa, transformando-a na primeira companhia pública a ter Bitcoin como reserva de valor no seu balanço. Saylor tem defendido publicamente o Bitcoin como uma proteção contra a inflação e uma alternativa mais segura ao dinheiro fiduciário. A sua aposta ajudou a legitimar o Bitcoin no mundo corporativo e inspirou outras empresas a seguir o seu exemplo.
A sua posição em relação ao Bitcoin tem sido clara: ele acredita que o futuro financeiro do mundo está no Bitcoin, e a sua empresa serve como um exemplo para outras grandes corporações a adotarem a moeda digital.
Resumindo, os pioneiros e investidores que contribuíram para o crescimento e a difusão do Bitcoin desempenharam papéis vitais na evolução desta tecnologia disruptiva. Desde o misterioso Satoshi Nakamoto até figuras como Hal Finney, Roger Ver, Tim Draper e Michael Saylor, o Bitcoin tem sido moldado por pessoas com uma visão única sobre o futuro do dinheiro e da liberdade financeira. Através da sua perseverança e crença no potencial do Bitcoin, esses indivíduos ajudaram a estabelecer as bases para a adoção global da moeda digital, transformando-a de uma ideia inovadora em uma força revolucionária no sistema financeiro. O futuro do Bitcoin dependerá, em grande parte, da continuidade da sua evolução e da adoção por mais pessoas e instituições, mas é indiscutível que os pioneiros e investidores desempenharam um papel fundamental na sua ascensão.

— Bitcoin Magazine (@BitcoinMagazine) June 16, 2025
Strategy added another 10,100 Bitcoin to its treasury between June 9 and June 15, 2025, according to a Form 8-K filed Monday with the SEC. The company spent approximately $1.05 billion on the latest allocation, paying an average price of $104,080 per Bitcoin, inclusive of fees and expenses.
This brings Strategy’s total holdings to 592,100 BTC, acquired at a cumulative cost of $41.84 billion, or an average price of $70,666 per Bitcoin, solidifying its status as the world’s largest corporate holder of Bitcoin.
The recent allocation was financed through multiple capital raises. Strategy tapped its STRK and STRF at-the-market offerings, and completed a $979.7 million public offering of STRD, its 10.00% Series A Perpetual Stride Preferred Stock, on June 10.
“The Bitcoin purchases were made using proceeds from the STRK ATM, STRF ATM, and STRD Offering,” the company stated.
In addition to the purchase, Strategy reported a 19.1% BTC yield year-to-date in 2025, reflecting the strength of its long-term bitcoin investment thesis.
This latest acquisition follows a series of steady purchases throughout 2024 and early 2025. Strategy has continued to scale its position quarter over quarter, using capital market tools to accumulate Bitcoin as part of its strategy.
“Strategy continues to execute on its commitment to the Bitcoin standard,” the company stated in its filing.
The company continues to emphasize transparency around its holdings. Its website, strategy.com, hosts a Bitcoin Dashboard that is regularly updated with BTC purchase details, securities activity, and performance metrics in compliance with Regulation FD.
Strategy’s move comes during increasing institutional adoption of Bitcoin in 2025. The company’s acquisition strategy and consistent messaging have made it a leader for corporate engagement with the digital asset.
With its most recent buy, Strategy now holds over 592,000 Bitcoin, a significant portion of the asset’s fixed 21 million supply—showing its view of Bitcoin not just as an investment, but as a core component of its financial strategy.

Senator Hagerty’s Vision Beyond The GENIUS Act: Make Tennessee A Hub For Bitcoin MiningSenator Bill Hagerty (R-TN) has been in the headlines as of late as the GENIUS Act (S. 1582), a bill for which he was the primary sponsor, moves closer to passing in the U.S. Senate.
The GENIUS Act is a bill that, if enacted into law, would create a federal regulatory framework for stablecoins so that the technology can be more widely adopted. (While some Bitcoin enthusiasts may not like this, they should still pay attention to the language in the bill, as it could have an impact on U.S. citizens’ ability to use Bitcoin wallets privately.)
However, stablecoins aren’t the only thing on Senator Hagerty’s mind.
He’s also thinking about how to best produce and harness energy in Tennessee to use it for Bitcoin mining and AI compute.
He shared his vision on this topic with me in an interview I conducted with him at Bitcoin 2025:
Tennessee As A Hub For Bitcoin Mining and AI Compute
“We have an opportunity before us to be in the very lead,” Senator Hagerty told Bitcoin Magazine in regard to building nuclear facilities that can be used to produce energy for Bitcoin mining and AI processing.
“The largest utility in the world is the Tennessee Valley Authority — certainly the largest one in America — and I think we’ve got a unique opportunity here to move forward and become the energy hub of America,” he added.
“[We should] see more and more not only mining operations, but if you think about what Elon Musk is doing in Memphis with xAI, the data centers, the opportunities with artificial intelligence — there are many, many things that are going to happen in Tennessee.”
The Senator added that he believes the state can also strike partnerships with Oak Ridge National Laboratory, Vanderbilt University, the University of Tennessee and Tennessee Tech as it works to become a more friendly destination for Bitcoin miners and data centers.
“We’ve got great opportunities [from] Memphis all the way across the state,” said Senator Hagerty.
Hagerty’s Call For Bipartisanship
Whether it’s working toward stablecoin legislation or crafting regulation that will enable industries like Bitcoin mining and data centers to thrive in the United States, Senator Hagerty believes these efforts should be inherently bipartisan.
“[These are] bipartisan — or nonpartisan issue[s] — frankly,” said the Senator.
“If you care about the competitiveness of America — if you want to see innovation happen on our shores rather than being pushed overseas — then you’re going to support what we’re trying to do in terms of putting a regulatory framework in place that will deliver certainty, that will create an ecosystem here in America that will allow these companies to thrive,” he added.
“It’s not just the stablecoin legislation I’m putting forward or what may happen with Bitcoin or other technologies like that. It’s the overall blockchain technology that’s going to help advance America beyond the 21st century. We need to stay in the lead. We can stay in the lead.”

2025-06-17 14:59:12Bitcoin é a primeira moeda digital descentralizada do mundo, criada em 2009 por um indivíduo ou grupo sob o pseudônimo de Satoshi Nakamoto. O seu nascimento marcou o início de uma revolução no sistema financeiro global, introduzindo um novo tipo de moeda que não é controlada pelos governos ou instituições financeiras tradicionais. A história do Bitcoin está profundamente enraizada nos ideais de liberdade económica, transparência e resistência à censura.
A jornada começou em outubro de 2008, quando Satoshi Nakamoto publicou um artigo intitulado “Bitcoin: A Peer-to-Peer Electronic Cash System”. O white paper, publicado na mailing list Cryptozoology, descreve a ideia de um sistema de pagamento digital baseado em uma rede peer-to-peer. Esse conceito elimina a necessidade de intermediários como bancos e resolve um problema conhecido como “gasto duplo” – possibilidade de replicação de moedas digitais – por meio de uma tecnologia chamada blockchain ou aquilo que o próprio Satoshi Nakamoto chamava de timechain.
O blockchain ou timechain é basicamente um livro-razão público e imutável que registra todas as transações do Bitcoin. Opera através de um sistema descentralizado, onde os participantes da rede (os chamados nós ou famosos nodes) verificam as transações e as organizam em blocos. Esses blocos são conectados por sua vez em uma cadeia contínua, formando a base para a segurança e transparência do sistema.
No dia 3 de janeiro de 2009, Satoshi Nakamoto extraiu o primeiro bloco do Bitcoin, conhecido como bloco gênese. O bloco continha uma mensagem codificada referenciando a crise financeira global de 2008: "The Times, 3 de janeiro de 2009, Chanceler à beira do segundo resgate bancário". Esta mensagem é emblemática da motivação por trás do Bitcoin: fornecer uma alternativa ao sistema financeiro centralizado que não conseguiu proteger a economia global.
Ao longo de 2009 e 2010, o Bitcoin permaneceu como um experimento entre os entusiastas da tecnologia e das criptomoedas. As primeiras transações de Bitcoin ocorreram entre participantes da rede, e o primeiro uso comercial da moeda ocorreu em 22 de maio de 2010, quando um programador chamado Laszlo Hanyecz comprou duas pizzas por 10 mil Bitcoins. Esta transação histórica foi apelidada de “Bitcoin Pizza Day”.
Satoshi Nakamoto continuou a contribuir para o desenvolvimento do Bitcoin até o final de 2010, quando desapareceu gradualmente da comunidade. Até hoje, sua identidade permanece um mistério e não há evidências concretas de quem ou quantas pessoas estavam por trás do pseudônimo. Antes de sair, Satoshi Nakamoto entregou o controle do projeto a outros desenvolvedores e deixou claro que o Bitcoin deveria ser uma tecnologia descentralizada, de propriedade de todos e controlada por ninguém.
Desde então, o Bitcoin cresceu exponencialmente. Cresceu de um experimento tecnológico para um ativo multibilionário e é amplamente considerada a forma legítima de moeda digital e reserva de valor. Governos, empresas e indivíduos em todo o mundo adotaram o Bitcoin como alternativa às moedas fiat tradicionais.
Resumindo, a criação do Bitcoin por Satoshi Nakamoto foi mais do que apenas o nascimento de uma moeda digital; Este foi o início de um movimento global para repensar a forma como o dinheiro é controlado e distribuído. Embora a identidade de Satoshi Nakamoto permaneça desconhecida, o seu legado continuará a moldar o futuro do sistema financeiro e a desafiar as estruturas económicas tradicionais.

2025-06-17 14:57:11The coffee tastes burnt. Dad stirs his black coffee with a plastic spoon. His hands shake a little. Seventy years of working hands.
"How are the girls?"
"Good. Emma lost her first tooth. Sophie's learning to ride her bike."
He smiles. First real smile I've seen from him in months.
"Remember when you learned? Took you all summer. Scraped knees every day. Kept getting back on."
A seagull lands on the window ledge. Fat from tourist scraps.
"Your mother says Sophie looks like you did at that age. Same stubborn streak."
"She gets that honest."
We watch people walk the beach. Families. Couples. Kids building sandcastles that won't last the tide.
"How's retirement treating you?"
"Can't complain. Get to spend time with the kids. Help with homework."
"Lucky man. Forty-three and done."
His coffee sits untouched now. Getting cold.
"Market's been crazy lately."
"Yeah?"
"Down thirty percent this year. Everything I put away for forty years. Just... gone."
The seagull flies away. Smarter than us.
"Your mother keeps watching the news. Every day it's worse. Says maybe we should sell. Cut our losses."
"Timing the market's tough."
"Tell me about it. Bought high. Always buy high."
An old couple walks past. Moving slow but still moving.
"Your uncle says it'll come back. Says to buy more while it's cheap. Easy for him to say."
"He's got different circumstances."
"That's what I told your mother. But you know how she listens to him."
Dad finally drinks his coffee. Makes a face. Cold and bitter.
"Your sister called yesterday."
"Yeah?"
"Needs money for the lawyer. Divorce is getting messy."
"Sorry to hear that."
"Can't say no to my kids. Even when they're forty-two."
His shoulders sag. Seventy years of carrying weight.
"How's the night shift?"
"Long. Double shifts most weeks."
"That's rough."
"Back's killing me. Feet hurt. Everything hurts."
The tide is going out. Leaving shells and debris on the sand.
"Mom's job situation?"
His face goes dark.
"They're shipping it overseas. AI's taking the rest. Forty years of experience. Means nothing now."
We sit in the quiet. Two men running out of safe ground.
"Dad?"
"Yeah?"
He looks at his hands. Working hands. Tired hands.
"Son, we can't retire."
The words hang between us like smoke. Everything we've been dancing around. Everything he's been trying not to say.
The market. The job. The sister. The uncle's bad advice. All of it leading here.
To this moment. This truth.
I want to fix it. Want to offer solutions. Want to give him some Bitcoin or a check.
But I don't.
The waitress brings the check. I reach for my wallet.
"I got it."
"Dad, let me—"
"I got it."
He counts out bills slowly. Leaves a decent tip.
Sometimes the best thing you can give someone is silence. Let them keep their dignity intact.
The ocean takes. The ocean gives back. But never what you expect.
Only what remains.

2025-06-17 14:56:53Bitcoin é uma moeda digital descentralizada criada em 2009 por um indivíduo ou grupo sob o pseudônimo de Satoshi Nakamoto. Ao contrário das moedas tradicionais emitidas pelo governo, como o dólar americano ou o euro, o Bitcoin não é controlado por nenhuma autoridade central, como um banco central ou uma instituição financeira. Esta característica inovadora tornou-o foco do debate económico, tecnológico e até mesmo social nos últimos anos.
O Bitcoin funciona com uma tecnologia chamada blockchain (que atualmente a comunidade Bitcoin prefere chamá-la de timechain), é essencialmente um livro digital distribuído. O blockchain ou timechain registra todas as transações feitas na rede Bitcoin de forma aberta e transparente. Cada bloco contém um conjunto de transações que são adicionadas de forma imutável à cadeia, assim que são verificadas pelos mineradores (mineradores são basicamente participantes da rede que usam seu poder computacional para verificar essas mesmas transações). Isto garante a segurança e evita fraudes, uma vez que nenhuma pessoa ou entidade pode alterar retroativamente os registos.
Uma das melhores características do Bitcoin é a sua oferta limitada. Apenas podem ser criados 21 milhões de Bitcoins, o que por este mesmo motivo o Bitcoin apresenta um carácter deflacionário, ao contrário da moeda fiduciária, que os bancos centrais podem imprimir em quantidades ilimitadas. Este limite fixo, combinado com o crescente interesse global pela tecnologia em geral e pela privacidade de modo individual impulsiona a valorização do Bitcoin ao passar do tempo.
Outra característica do Bitcoin é que ele permite transações diretas entre pessoas, eliminando intermediários. Isto é particularmente útil em cenários como transferências internacionais, onde o Bitcoin pode ser utilizado para enviar dinheiro rapidamente e com taxas reduzidas, sem ter que passar por um banco ou serviços financeiros tradicionais no geral. Além disso, é visto como uma forma de liberdade financeira em países com moedas locais instáveis (quase sempre efeito dos bancos centrais imprimem dinheiro de forma completamente descontolada) ou controlos rígidos estatais sobre o capital.
Porém, o Bitcoin não está imune a críticas que tendem sempre a ser críticas vazias que mascaram os interesses pessoais de quem as faz, seja porque trabalham em bancos ou corretoras tradicionais e têm medo de perder o “poder” ou até mesmo o emprego ou então porque têm más intenções e querem vender as suas criptomoedas que no fundo são todas inúteis (as famosas shitcoins). As oscilações de preço do Bitcoin também podem significar riscos enormes para usuários que são no fundo iniciantes, compram por determinado preço e acabam por vender quando o valor caiu pela metade (perdendo pelo menos metade do seu dinheiro). Por outro lado, muitos especialistas consideram o Bitcoin um marco tecnológico e social que desafia os modelos económicos existentes.
Resumindo, o Bitcoin é muito mais do que uma “crypto“ ou “criptomoeda“. Representa uma revolução ou revisão na forma como a maioria dos seres humanos pensam sobre o dinheiro, proporcionando uma alternativa descentralizada, transparente e resistente ao roubo ou atê mesmo à censura. Embora ainda enfrente alguns desafios para ser amplamente aceite por alguns cépticos e por alguns governos preocupados com a perda de controlo das “suas” próprias populações (como mencionado anteriormente), o seu impacto tem sido inegável, abrindo caminho para uma nova era na economia global e abrindo a mente de muitas pessoas para a reflexão.
