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 17:23:55A 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.

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 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 18:01:30Bluebird 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.

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.

2025-06-17 16:02:09Carl 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 18:02:14A 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.

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.”

2025-06-17 16:02:01The 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 15:22:49A 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 15:19:29A mineração de Bitcoin é um processo crucial para o funcionamento e a segurança da rede. Ela tem um papel importante na validação de transações e na geração de novos bitcoins, garantindo a integridade do sistema baseado em blockchain ou timechain. Esse processo envolve resolver cálculos matemáticos complicados, exigindo grande poder computacional. Além disso, a mineração tem efeitos econômicos, ambientais e tecnológicos que devem ser analisados de forma detalhada.
A mineração de Bitcoin é o procedimento pelo qual novas unidades da moeda são criadas e adicionadas à rede. Ela também é responsável por verificar e registrar transações no blockchain ou timechain. Esse sistema foi criado para ser descentralizado, eliminando a necessidade de uma autoridade central para controlar a emissão ou validar operações.
Os participantes do processo, chamados de mineradores, competem para resolver problemas matemáticos difíceis. Aquele que achar a solução primeiro ganha o direito de adicionar um novo bloco ao blockchain ou timechain e recebe uma recompensa em bitcoins, além das taxas de transação que estão no bloco. Esse mecanismo é chamado de prova de trabalho (Proof of Work - PoW).
O processo de mineração é muito técnico e segue uma série de etapas:
Agrupamento de transações: as transações enviadas pelos usuários são reunidas em um bloco pendente, que aguarda validação.
Resolução de problemas matemáticos: os mineradores devem encontrar um número específico, chamado nonce, que, quando combinado com os dados do bloco, gera um hash criptográfico dentro de um padrão exigido. Esse processo requer tentativa e erro, consumindo alto poder computacional.
Validação do bloco: quando um minerador encontra a solução correta, o bloco é validado e adicionado ao blockchain ou timechain. Todos os nós da rede verificam a autenticidade do bloco antes de aceitá-lo.
Recompensa: o minerador que vencer recebe uma recompensa em bitcoins, além das taxas pagas pelas transações que estão no bloco. Essa recompensa diminui ao longo do tempo em um evento chamado halving, que acontece aproximadamente a cada quatro anos.
A mineração de Bitcoin tem um impacto econômico grande, pois cria oportunidades de renda para pessoas e empresas. Ela também estimula o desenvolvimento de novas tecnologias, como processadores especializados (ASICs) e sistemas de resfriamento modernos.
Além disso, a mineração apoia a inclusão financeira ao manter uma rede descentralizada, permitindo transações rápidas e seguras em nível global. Em áreas com economias instáveis, o Bitcoin oferece uma alternativa viável para preservação de valor e transferências financeiras.
Apesar de seus benefícios econômicos, a mineração de Bitcoin é frequentemente criticada por seu impacto no meio ambiente. O processo de prova de trabalho consome grandes quantidades de eletricidade, especialmente em áreas onde a matriz energética depende de fontes fósseis.
Estima-se que a mineração de Bitcoin consuma tanta energia quanto alguns países inteiros, levantando preocupações sobre sua sustentabilidade. No entanto, há esforços contínuos para reduzir esses impactos, como o uso crescente de fontes de energia renovável e soluções alternativas, como redes baseadas na prova de participação (Proof of Stake - PoS) em outros sistemas descentralizados.
A mineração também enfrenta desafios ligados à escalabilidade e à concentração de poder computacional. Grandes empresas e pools de mineração dominam o setor, o que pode afetar a descentralização da rede.
Outro desafio é a complexidade crescente dos cálculos matemáticos, que exige hardware mais avançado e consome mais energia com o tempo. Para enfrentar esses problemas, pesquisadores estudam soluções que otimizem o uso de recursos e mantenham a rede sustentável por um longo período.
Resumindo, a mineração de Bitcoin é um processo essencial para manter a rede e para a criação de novas unidades da moeda. Ela garante segurança, transparência e descentralização, sustentando o funcionamento do blockchain ou timechain.
No entanto, a mineração também traz desafios, como o alto consumo de energia e a concentração de recursos em grandes pools. Apesar disso, a busca por soluções sustentáveis e inovações tecnológicas indica um futuro promissor, onde o Bitcoin continuará a ter um papel central na economia digital.

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.
JUST IN:
Thailand’s cabinet approved personal tax waiver on profits from the #Bitcoin and crypto sale over five years. pic.twitter.com/4gWc1gn84j
— 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.

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.

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

— 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.

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 05:54:52ปี 1937 — บริษัท Hormel Foods Corporation ในเมืองออสติน รัฐมินนิโซตา สหรัฐฯ ชายคนหนึ่งชื่อ Jay C. Hormel ลูกชายของผู้ก่อตั้งบริษัท มีไอเดียแสนทะเยอทะยานว่า “อยากทำผลิตภัณฑ์จากหมู ที่เก็บได้นาน ไม่ต้องแช่เย็น และไม่แพง”
เพราะตอนนั้น หมูเหลือเยอะ โดยเฉพาะ “หัวไหล่หมู” ที่ขายไม่ออก เพราะมันไม่ใช่ชิ้นเนื้อพรีเมียมที่คนอยากซื้อไปทำอาหาร เจย์เลยทดลองบดเนื้อไหล่หมู เติมเกลือ น้ำตาล สารกันเสีย โซเดียมไนไตรต์ และสิ่งสำคัญสุดคือ เจลาตินจากน้ำต้มกระดูก เพื่อให้เนื้อเกาะตัว ไม่แห้ง และอยู่ได้นานโดยไม่ต้องแช่เย็น
ผลลัพธ์คือ หมูกระป๋อง 340 กรัมในกล่องสี่เหลี่ยม พร้อมเปิดฝาดึงด้วยมือ ไม่ต้องใช้ที่เปิดกระป๋อง ชูความ ราคาถูก เก็บง่าย พกพาสะดวก และไม่ต้องปรุงอะไรเพิ่มเติม ซ่อนความของเหลือเอาไว้เงียบๆ
และเพื่อให้คนจำได้ง่าย บริษัทจัดประกวดตั้งชื่อ และผู้ชนะเสนอคำว่า “Spam” = Spiced Ham (แต่ไม่มีใครรู้จริงๆ ว่าย่อจากอะไรแน่) แค่ “สั้น จัดจ้าน และจำง่าย” ก็พอ
เมื่อเกิดสงครามโลกครั้งที่ 2 ในปี 1939 สหรัฐฯ ยังไม่เข้าสงครามเต็มตัว แต่เริ่มเตรียมเสบียงสนับสนุนพันธมิตร และ Spam กลายเป็นของขวัญจากพระเจ้า เพราะ เก็บได้นานหลายปี ไม่ต้องแช่เย็น น้ำหนักเบา เปิดง่าย ไม่เสียง่ายแม้เจอฝุ่น โคลน หรือไอร้อนจากปืนใหญ่
รัฐบาลสหรัฐฯ เริ่มจัดสั่ง Spam ให้กับกองทัพในสัดส่วนที่มากขึ้นเรื่อยๆ โดยเฉพาะทหารแนวหน้าในยุโรปและแปซิฟิก เช่น ฮาวาย, ฟิลิปปินส์, กวม, และเกาหลี ระหว่างสงคราม Hormel ผลิต Spam มากถึง 15 ล้านกระป๋องต่อสัปดาห์ และส่งออกไปมากกว่า 100 ล้านกระป๋อง ภายในเวลาไม่กี่ปี
Jay C. Hormel ถือว่ามีบทบาททางสังคมและการเมืองอยู่ไม่น้อย โดยเฉพาะช่วงก่อนสงครามโลกครั้งที่ 2
เขาเคยเป็นสมาชิกของ America First Committee ซึ่งเป็นกลุ่มเคลื่อนไหวทางการเมืองที่มีอิทธิพลมากในช่วงก่อนสงครามโลกครั้งที่ 2 โดยกลุ่มนี้มีเป้าหมายคือ “ต่อต้านการที่อเมริกาจะเข้าไปร่วมสงครามในยุโรป” สมาชิกของกลุ่มนี้มีทั้งนักธุรกิจใหญ่ สื่อมวลชน นักวิชาการ รวมถึงชาร์ลส ลินด์เบิร์ก (นักบินชื่อดัง) เรียกได้ว่าเป็นกลุ่มที่มีอิทธิพลเชิงความคิดและการเมืองในช่วงปลายยุค 1930s
แม้ในตอนแรก Hormel จะมีแนวคิดไม่เห็นด้วยกับการเข้าสงคราม แต่พอสงครามเริ่มต้นจริง และสหรัฐฯ ต้องส่งทหารและเสบียงออกไปรบ เขาก็ “ปรับตัวทันที” และกลายเป็นหนึ่งในผู้จัดหาอาหารรายใหญ่ให้กองทัพ โดยเฉพาะ Spam ที่ผลิตส่งเป็นล้านกระป๋องต่อสัปดาห์ ซึ่งแน่นอนว่าไม่มีทางทำได้ถ้าไม่มีความสัมพันธ์และการประสานงานกับภาครัฐโดยตรง
หลังสงครามโลกสิ้นสุดในปี 1945 สิ่งที่รัฐบาลและภาคธุรกิจต้องเจอคือ จะทำยังไงกับโรงงานผลิตอาหารที่เคยทำเพื่อ “เลี้ยงทหารนับล้าน” แต่ตอนนี้ไม่มีสงครามแล้ว? Hormel ไม่ยอมให้ Spam หายไปจากโต๊ะอาหารโลกง่ายๆ แผนการตลาดที่ฉลาดมากของพวกเขาคือ 1. “Sell the nostalgia” ขายความทรงจำ! คนอเมริกันที่เป็นทหารผ่านศึก กลับมาใช้ชีวิตปกติ แต่ก็ยังคุ้นเคยกับ Spam อยู่แล้ว ก็ขายให้พวกเขานั่นแหละ 2. “ผูกกับอาหารเช้า” Hormel ทำสูตร “Spam and eggs” และโฆษณาว่าเป็นอาหารเช้าที่ให้พลังงาน ย่อยง่าย และเหมาะกับทุกครอบครัว 3. เจาะตลาดประเทศที่ได้รับ Spam ระหว่างสงคราม ฟิลิปปินส์, ฮาวาย, ญี่ปุ่น, เกาหลีใต้, อังกฤษ กลายเป็นตลาดหลัก บางประเทศพัฒนาเมนูท้องถิ่นกับ Spam เช่น ฟิลิปปินส์ Spam silog (Spam + ข้าว + ไข่ดาว), เกาหลี 부대찌개 (Budae-jjigae) หรือหม้อไฟทหาร, ญี่ปุ่น Spam onigiri, ฮาวาย Spam musubi (สแปมวางบนข้าว ปิดด้วยสาหร่าย) 4. สร้างแบรนด์ให้รัก Hormel สนับสนุนการจัดงานเทศกาล Spam (เช่น Spam Jam) และทำให้แบรนด์กลายเป็น Pop Culture ของอเมริกา เพื่อโปรโมตแบรนด์ให้เป็นของอเมริกันจ๋า ทั้งน่ารัก ทั้งเท่ ทั้งกินง่าย และกลายเป็นความภูมิใจของชนชั้นกลาง
ระหว่างปี 1937–1946 Spam สร้างชื่อให้ Hormel อย่างถล่มทลาย ถึงขั้นรัฐบาลโซเวียตยังเคยร้องขอให้สหรัฐฯ ส่ง Spam เข้าโซเวียตเพื่อเลี้ยงทหารแนวหน้า โดย นายพล Dwight D. Eisenhower (ต่อมาคือประธานาธิบดีสหรัฐฯ) เคยกล่าวว่า “I ate my share of Spam along with millions of other soldiers. I’ll even confess to a few unkind remarks about it—uttered during the strain of battle... But as former Commander in Chief, I believe I can still see Spam in my dreams.” (ฉันกิน Spam มากพอๆ กับทหารหลายล้านคน แม้จะเคยบ่นบ้าง แต่ในฐานะอดีตแม่ทัพใหญ่...ฉันยังฝันเห็นมันเลย)
Jay C. Hormel ไม่ใช่แค่คนขายหมู แต่เขาเป็นนักวางระบบอุตสาหกรรมขั้นเทพ สามารถยกระดับกิจการท้องถิ่นของพ่อให้กลายเป็นบริษัทอาหารที่ส่งออกระดับโลกได้ เขาเป็น early adopter ของสิ่งที่เรียกว่า vertical integration คือควบคุมทุกขั้นตอน ตั้งแต่ฟาร์ม โรงฆ่าสัตว์ โรงงาน บรรจุภัณฑ์ จนถึงการขนส่งและการตลาด
ในปี 1970s รายการตลกชื่อดังของอังกฤษอย่าง Monty Python’s Flying Circus ได้เอา Spam มาเล่นมุกในตอนหนึ่ง โดยฉากคือร้านอาหารที่ทุกเมนูมี Spam อยู่ในนั้น แล้วลูกค้าพยายามสั่งอาหารโดยไม่เอา Spam แต่ร้านไม่ยอม เพราะ “เมนูเรามี Spam ทุกอย่าง!” จนเสียงลูกค้ากับแม่ค้ากลายเป็นการโต้เถียงอันแสนตลก และมีนักแสดงแต่งเป็นไวกิ้งยืนร้อง “Spam, Spam, Spam, Spam...” ซ้ำๆ อยู่ด้านหลังแบบไม่รู้จบ https://youtu.be/anwy2MPT5RE?si=-68WQeng47lhJENJ
ฉากนั้นกลายเป็นตำนานในโลกตลก และคำว่า “Spam” ก็เริ่มถูกใช้เป็นคำสแลงหมายถึง “ของที่ซ้ำซาก ไร้สาระ รบกวน” ซึ่งต่อมาก็กลายเป็นคำที่เราใช้เรียกอีเมลหรือข้อความขยะนั่นเอง
จะว่าไปแล้ว Spam ถือเป็น “สินค้าที่ครอบงำและเปลี่ยนแปลงอาหารของโลกอีกตัวนึง” อย่างแท้จริง จากเศษหมูไร้คนซื้อ → สินค้าแห่งนวัตกรรมอาหาร → เสบียงสงคราม → อาหารเช้าคลาสสิก → วัฒนธรรมท้องถิ่น → Meme ตลก → และสุดท้ายก็กลายเป็นคำด่าบนอินเทอร์เน็ต
Jay C. Hormel ไม่ได้เป็นนักการเมือง แต่เขาเป็น “นักอุตสาหกรรมที่มีบทบาททางการเมือง” โดยเฉพาะในช่วงเปลี่ยนผ่านของประเทศจาก “ไม่เอาสงคราม” ไปสู่ “ต้องชนะสงคราม”
เขาอาจเริ่มจากแนวคิด “อย่ายุ่งเรื่องคนอื่น” แต่พอเห็นว่าโอกาสมา เขาก็เปลี่ยนโหมดทันที และทำให้ Spam กลายเป็นเสบียงระดับชาติ แบบนี้แหละเฮียถึงบอกว่า “สงครามทำให้คนธรรมดากลายเป็นตำนาน” ...หรือไม่ก็ “สงครามทำให้ธุรกิจธรรมดากลายเป็นธุรกิจผูกขาดที่ไม่มีใครเลิกกินได้อีกเลย”
Spam ไม่ใช่แค่อาหารกระป๋อง แต่เป็นเครื่องมือทางภูมิสงคราม อุตสาหกรรม และการตลาด จากห้องครัวทดลองเล็กๆ ในมินนิโซตา กลายเป็นไอเท็มในสนามรบระดับโลก และสุดท้าย…ก็กลายเป็นทั้ง อาหารในตู้, มุกในมุขตลก, และ คำด่าบนโลกออนไลน์ ทั้งหมดนี้เริ่มต้นจากคำเดียว... "หมูมันเหลือ"

2025-06-17 05:02:27This 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
Geyser Fund
Widget
Email
The Giving Block

SatSale (GitHub)
Lightweight, self-hosted Bitcoin/Lightning payment processor. No KYC.
Ideal for developers comfortable with server management. Simple to deploy, supports both on-chain and Lightning, and integrates with WooCommerce.
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
Geyser Fund
Crowdfunding platform. Widget-based, connects to your wallet, email registration.Focused on Bitcoin crowdfunding, memberships and donations.
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.
I hope this article helped you. If you added bitcoin donations, share your link in the comments and I will send you a few satoshis maybe

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

"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 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.

2025-06-17 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.

2025-06-16 19:02:15Nostr is an open communication protocol that can be used to send messages across a distributed set of relays in a censorship resistant and robust way.
If you missed my nostr introduction post you can find it here. My nostr account can be found here.
We are nearly at the point that if something interesting is posted on a centralized social platform it will usually be posted by someone to nostr.
We are nearly at the point that if something interesting is posted exclusively to nostr it is cross posted by someone to various centralized social platforms.
We are nearly at the point that you can recommend a cross platform app that users can install and easily onboard without additional guides or resources.
As companies continue to build walls around their centralized platforms nostr posts will be the easiest to cross reference and verify - as companies continue to censor their users nostr is the best censorship resistant alternative - gradually then suddenly nostr will become the standard. 🫡

2025-06-16 17:02:09The 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.
If you have never used lightning before, use this guide to get started on your phone.

2025-06-16 17:02:09What 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.

2025-06-16 17:02:08The newly proposed RESTRICT ACT - is being advertised as a TikTok Ban, but is much broader than that, carries a $1M Fine and up to 20 years in prison️! 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

2025-06-17 17:01:58Marty's Bent
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.

2025-06-16 17:02:07Bank 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.

2025-06-17 17:01:55French 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.

2025-06-16 17:02:07People 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 17:01:55The 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.

2025-06-17 17:01:54Russian 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.

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.

2025-06-17 17:01:53The 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.

2025-06-17 17:01:51VanEck 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.”

2025-06-17 17:01:50The 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.

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.
JUST IN: Coinbase launches credit card allowing users to earn up to 4% bitcoin back on every purchase
pic.twitter.com/d6pdNZV4pi
— 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 17:01:49A 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 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 17:01:38BlackRock’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.

2025-06-17 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

2025-06-16 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
- 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.
What's Next?
This is just the beginning. We will be constantly working to improve KYCnot.me and add more features that help you preserve your privacy.
Remember: True financial freedom requires the right to privacy. Stay KYC-free!

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.

2025-06-16 04:01:35Key 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 18:01:39The 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.
The post Stratum V2 increases profits by 7.4%: “The study shows that profit and decentralization can coexist”, says Vernetti, SV2 maintainer appeared first on Atlas21.

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.

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.

2025-06-16 04:01:22CANNES, 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.

2025-06-17 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.
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.

2025-06-17 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.

- The latest firmware updates for COLDCARD devices introduce two major features: COLDCARD Co-sign (CCC) and Key Teleport between two COLDCARD Q devices using QR codes and/or NFC with a website.
What's new
- COLDCARD Co-Sign: When CCC is enabled, a second seed called the Spending Policy Key (Key C) is added to the device. This seed works with the device's Main Seed and one or more additional XPUBs (Backup Keys) to form 2-of-N multisig wallets.
- The spending policy functions like a hardware security module (HSM), enforcing rules such as magnitude and velocity limits, address whitelisting, and 2FA authentication to protect funds while maintaining flexibility and control, and is enforced each time the Spending Policy Key is used for signing.
- When spending conditions are met, the COLDCARD signs the partially signed bitcoin transaction (PSBT) with the Main Seed and Spending Policy Key for fund access. Once configured, the Spending Policy Key is required to view or change the policy, and violations are denied without explanation.
"You can override the spending policy at any time by signing with either a Backup Key and the Main Seed or two Backup Keys, depending on the number of keys (N) in the multisig."
-
A step-by-step guide for setting up CCC is available here.
-
Key Teleport for Q devices allows users to securely transfer sensitive data such as seed phrases (words, xprv), secure notes and passwords, and PSBTs for multisig. It uses QR codes or NFC, along with a helper website, to ensure reliable transmission, keeping your sensitive data protected throughout the process.
- For more technical details, see the protocol spec.
"After you sign a multisig PSBT, you have option to “Key Teleport” the PSBT file to any one of the other signers in the wallet. We already have a shared pubkey with them, so the process is simple and does not require any action on their part in advance. Plus, starting in this firmware release, COLDCARD can finalize multisig transactions, so the last signer can publish the signed transaction via PushTX (NFC tap) to get it on the blockchain directly."
- Multisig transactions are finalized when sufficiently signed. It streamlines the use of PushTX with multisig wallets.
- Signing artifacts re-export to various media. Users are now provided with the capability to export signing products, like transactions or PSBTs, to alternative media rather than the original source. For example, if a PSBT is received through a QR code, it can be signed and saved onto an SD card if needed.
- Multisig export files are signed now. Public keys are encoded as P2PKH address for all multisg signature exports. Learn more about it here.
- NFC export usability upgrade: NFC keeps exporting until CANCEL/X is pressed.
- Added Bitcoin Safe option to Export Wallet.
- 10% performance improvement in USB upload speed for large files.
- Q: Always choose the biggest possible display size for QR.
Fixes
- Do not allow change Main PIN to same value already used as Trick PIN, even if Trick PIN is hidden.
- Fix stuck progress bar under
Receiving...
after a USB communications failure. - Showing derivation path in Address Explorer for root key (m) showed double slash (//).
- Can restore developer backup with custom password other than 12 words format.
- Virtual Disk auto mode ignores already signed PSBTs (with “-signed” in file name).
- Virtual Disk auto mode stuck on “Reading…” screen sometimes.
- Finalization of foreign inputs from partial signatures. Thanks Christian Uebber!
- Temporary seed from COLDCARD backup failed to load stored multisig wallets.

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 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 18:01:36Trump Media & Technology Group is targeting the digital asset market by registering a Bitcoin and Ethereum exchange-traded fund (ETF) with NYSE Arca.
On June 16, Truth Social — a company controlled by Trump Media & Technology Group — officially submitted documentation for a Bitcoin and Ethereum-based Exchange Traded Fund (ETF) to the U.S. Securities and Exchange Commission (SEC).

— James Seyffart (@JSeyff) June 16, 2025
This initiative would allow the social media platform to diversify its operations by entering the digital asset sector through these financial products.
The filing proposes a trust structure that would directly hold bitcoin and ether, with 75% of the fund’s assets invested in bitcoin and 25% in ether.
The Truth Social Bitcoin and Ethereum ETF will have Yorkville America Digital as the fund’s sponsor, while custody of the digital assets will be entrusted to the Crypto.com exchange.
The choice of NYSE Arca as the listing venue for the fund is no coincidence: this market already hosts several cryptocurrency-linked ETFs and offers the necessary technological infrastructure to manage these financial instruments.
Trump Media & Technology Group’s move aligns with a broader trend in which public companies are increasingly integrating Bitcoin and other digital assets into their corporate treasuries.
Devin Nunes, CEO of Trump Media & Technology Group, stated:
“Trump Media’s vision is to aggressively enhance our offerings and capabilities, which includes holding bitcoin in our corporate treasury.”
The final approval of the Truth Social Bitcoin and Ethereum ETF will depend on the outcome of the regulatory review process at the SEC, which must assess the product’s compliance with current regulations on exchange-traded funds and cryptocurrency investments.

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.”

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.

2025-06-17 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 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.

2025-06-15 14:46:22“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 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.
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 16:40:19kycnot.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.

2025-06-15 13:49:52Over 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.

2025-06-17 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.

2025-06-17 18:01:32The Thai government has eliminated taxes on gains from cryptocurrencies until 2029 to attract investors and promote the digital asset sector.
According to Efinance Thai, Thailand has approved a five-year tax exemption on profits from the sale of Bitcoin and other digital assets. The decision aims to position the country as one of the world’s leading digital financial hubs.
On June 17, Thailand’s Cabinet officially approved the tax measure proposed by the Ministry of Finance. The initiative removes personal income tax on capital gains from the sale of cryptocurrencies conducted through licensed operators under the 2018 Digital Asset Business Act.
Deputy Finance Minister Julapun Amornvivat stated that the tax policy is a cornerstone of the government’s strategy to turn Thailand into a major global center for Bitcoin and blockchain-based financial services.
The capital gains tax exemption will be in effect from January 1, 2025, to December 31, 2029. It applies exclusively to transactions carried out via exchanges, brokers, and dealers licensed and regulated by Thailand’s Securities and Exchange Commission (SEC).
Thai authorities estimate that this tax reform will boost the domestic Bitcoin market, generating positive spillovers for the country’s innovative tech ecosystem. Economic projections indicate a medium-term increase in tax revenues of at least 1 billion baht (around $30 million), driven by sector growth and fresh investment inflows.
According to the government, the initiative is also expected to encourage capital raising through digital tokens and foster the development of blockchain-based financial services.

2025-06-17 16:40:18These reviews are sponsored, yet the sponsorship does not influence the outcome of the evaluations. 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. Reviews are in collaboration with Orangefren.
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 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.
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!

2025-06-15 11:51:26I'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.

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.
You can also contact them via email at:

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 17:54:26Bitcoin, desde a sua criação, tem sido um dos ativos mais debatidos no mundo financeiro, tanto pelos seus seguidores apaixonados quanto pelos céticos. A sua volatilidade extrema e o impacto que tem causado no sistema financeiro tradicional tornaram-no objeto de especulação constante. À medida que o tempo passa, a adoção de Bitcoin cresce e surgem novas discussões sobre o seu futuro, tanto no que diz respeito ao seu preço quanto à sua integração no sistema financeiro global. Neste contexto, existem várias previsões para o futuro de Bitcoin, com cenários tanto otimistas quanto cautelosos, baseados em fatores como regulamentação, adoção institucional e inovação tecnológica.
O preço de Bitcoin: previsões e fatores de influência
Adoção Institucional: A crescente adoção de Bitcoin por grandes empresas e investidores institucionais tem sido vista como um fator de valorização. Organizações como Tesla, MicroStrategy e Square já incorporaram Bitcoin nas suas reservas de tesouraria, o que gerou uma maior confiança no ativo como uma reserva de valor. À medida que mais empresas sigam esse caminho, a demanda por Bitcoin pode aumentar, pressionando o preço para cima.
Regulação Governamental: A forma como os governos lidam com Bitcoin é um dos maiores fatores de incerteza. Uma regulação excessiva pode restringir o acesso e diminuir o interesse, enquanto uma abordagem mais amigável pode impulsionar a adoção e aumentar o preço. Em países como El Salvador, que adotaram o Bitcoin como moeda legal, observa-se uma tendência positiva, mas em muitas outras nações, a regulação ainda é um grande desafio.
Oferta Limitada: A oferta de Bitcoin é limitada a 21 milhões de unidades, o que significa que não há risco de inflação ou aumento da quantidade disponível. Este facto torna Bitcoin particularmente atraente como reserva de valor, especialmente em tempos de incerteza económica global, o que pode continuar a impulsionar a sua valorização a longo prazo.
Tecnologia e Escalabilidade: Inovações como a Lightning Network e o Taproot, que visam melhorar a escalabilidade e a eficiência das transações, podem contribuir para uma adoção mais ampla, o que, por sua vez, poderia ter um impacto positivo no preço. Se Bitcoin se tornar mais acessível e viável para transações diárias, a sua utilidade será mais valorizada no mercado.
Adoção global do Bitcoin: o caminho para a inclusão financeira
A adoção global de Bitcoin está a crescer, especialmente em regiões onde os sistemas financeiros tradicionais são ineficazes ou limitados. Países com economias instáveis, como nações com alta inflação ou crise cambial, estão cada vez mais a ver no Bitcoin uma alternativa viável. Além disso, a inclusão financeira é um dos maiores motores dessa adoção, uma vez que Bitcoin pode oferecer serviços financeiros a populações que estão fora do alcance dos bancos tradicionais.
Mercados Emergentes: Em países como o Brasil, Argentina, Nigéria e outros mercados emergentes, a procura por Bitcoin tem crescido, pois as pessoas procuram proteger os seus ativos da desvalorização das suas moedas locais. Nesses locais, Bitcoin surge como uma alternativa de reserva de valor e meio de troca que não está sujeita ao controlo de uma autoridade central.
Adoção por Governos e Empresas: A crescente aceitação de Bitcoin por grandes empresas e governos pode acelerar a sua integração nas economias globais. Países como El Salvador demonstraram que é possível adotar Bitcoin como uma moeda oficial, enquanto grandes empresas estão cada vez mais a aceitar Bitcoin como forma de pagamento, o que legitima ainda mais o seu uso no comércio global.
Educação e Acessibilidade: A medida que mais pessoas compreendem o funcionamento do Bitcoin e as suas vantagens em termos de segurança, privacidade e liberdade financeira, a adoção tende a crescer. A simplicidade das plataformas de exchange e as melhorias em termos de usabilidade das carteiras digitais tornam mais fácil para os utilizadores entrarem no mercado e utilizarem Bitcoin no seu dia a dia.
Cenários futuros: otimismo ou cautela?
O futuro do Bitcoin é incerto, mas diversos cenários podem se desenrolar. O cenário otimista aponta para uma maior valorização e adoção global, impulsionada pela inovação tecnológica, aumento da confiança institucional e a busca por uma alternativa descentralizada ao sistema financeiro tradicional. Nesse cenário, Bitcoin poderia tornar-se uma forma amplamente aceite de pagamento e uma reserva de valor global, com preços que poderiam ultrapassar os valores mais elevados já registados.
Por outro lado, o cenário cauteloso sugere que os obstáculos como regulação governamental, competição com outras moedas digitais e possíveis falhas tecnológicas podem impedir que o Bitcoin se torne uma parte central do sistema financeiro. Além disso, a volatilidade do preço pode desencorajar aqueles que buscam estabilidade e segurança.
Resumindo, as previsões sobre o preço e a adoção global de Bitcoin são, sem dúvida, complexas e influenciadas por vários fatores. O futuro do Bitcoin dependerá de como a sociedade, os governos e as empresas responderão a essa nova forma de dinheiro. Embora o potencial de valorização seja significativo, o risco e a volatilidade são características que não podem ser ignoradas. À medida que a adoção global cresce e a tecnologia evolui, será necessário acompanhar de perto os desenvolvimentos que irão moldar o futuro de Bitcoin no sistema financeiro global.

2025-06-15 10:02:45- This version introduces the Soroban P2P network, enabling Dojo to relay transactions to the Bitcoin network and share others' transactions to break the heuristic linking relaying nodes to transaction creators.
- Additionally, Dojo admins can now manage API keys in DMT with labels, status, and expiration, ideal for community Dojo providers like Dojobay. New API endpoints, including "/services" exposing Explorer, Soroban, and Indexer, have been added to aid wallet developers.
- Other maintenance updates include Bitcoin Core, Tor, Fulcrum, Node.js, plus an updated ban-knots script to disconnect inbound Knots nodes.
"I want to thank all the contributors. This again shows the power of true Free Software. I also want to thank everyone who donated to help Dojo development going. I truly appreciate it," said Still Dojo Coder.
What's new
- Soroban P2P network. For MyDojo (Docker setup) users, Soroban will be automatically installed as part of their Dojo. This integration allows Dojo to utilize the Soroban P2P network for various upcoming features and applications.
- PandoTx. PandoTx serves as a transaction transport layer. When your wallet sends a transaction to Dojo, it is relayed to a random Soroban node, which then forwards it to the Bitcoin network. It also enables your Soroban node to receive and relay transactions from others to the Bitcoin network and is designed to disrupt the assumption that a node relaying a transaction is closely linked to the person who initiated it.
- Pushing transactions through Soroban can be deactivated by setting
NODE_PANDOTX_PUSH=off
indocker-node.conf
. - Processing incoming transactions from Soroban network can be deactivated by setting
NODE_PANDOTX_PROCESS=off
indocker-node.conf
.
- Pushing transactions through Soroban can be deactivated by setting
- API key management has been introduced to address the growing number of people offering their Dojos to the community. Dojo admins can now access a new API management tab in their DMT, where they can create unlimited API keys, assign labels for easy identification, and set expiration dates for each key. This allows admins to avoid sharing their main API key and instead distribute specific keys to selected parties.
- New API endpoints. Several new API endpoints have been added to help API consumers develop features on Dojo more efficiently:
- New:
/latest-block
- returns data about latest block/txout/:txid/:index
- returns unspent output data/support/services
- returns info about services that Dojo exposes
- Updated:
/tx/:txid
- endpoint has been updated to return raw transaction with parameter?rawHex=1
- The new
/support/services
endpoint replaces the deprecatedexplorer
field in the Dojo pairing payload. Although still present, API consumers should use this endpoint for explorer and other pairing data.
- New:
Other changes
- Updated ban script to disconnect inbound Knots nodes.
- Updated Fulcrum to v1.12.0.
- Regenerate Fulcrum certificate if expired.
- Check if transaction already exists in pushTx.
- Bump BTC-RPC Explorer.
- Bump Tor to v0.4.8.16, bump Snowflake.

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.
NOTE: These reviews are sponsored, yet the sponsorship does not influence the outcome of the evaluations. 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.

2025-06-15 09:38:50M of N 분산
이번 5월 BSL 컨퍼런스와 비트코인 서울 2025 컨퍼런스에서 펜락(Penlock) 프로젝트에 참여하고 있는 한 분을 만났다. 아마 이 분을 만난 한국인 분들이 더 있을 텐데, 현재는 익명을 원하시므로 프라이버시 보호를 위해 실명을 언급하는 것은 주의하는 것이 좋겠다.
키를 M of N으로 분산하는 방식 중 내가 알고 있는 건 멀티시그와 샤미르 분산이다.
멀티시그는 각자가 키를 생성하지만,
1. 스크립트 길이가 길어지고, 스크립트를 해시로 감싼다고 해도 일반 주소보다 길다.
2. 일반적인 P2MS는 공개키가 드러나므로 프라이버시 보장이 안 되고, P2SH로 감싸도 서명할 때 각자의 공개키가 드러난다(리딤 스크립트가 드러나므로).
이런 특징을 갖고 있다.
샤미르 분산은 하나의 키를 분산하는 방식이므로,
1. 키를 복원했을 때는 결국 하나의 키가 생성되므로 키가 복원되었을 때 보안에 매우 주의해야 한다.
2. 하지만 외부에서 볼 때는 어떤 방식으로 분할이 되었는지 알 수가 없으므로 프라이버시에 좋다.
이런 특징을 갖고 있다.
M of N은 회사에서의 권한 분산, 상속, 위험 지점 분산, 신뢰 지점 분산 등에 사용할 수 있을 것이다. 하지만 나는 멀티시그와 샤미르 분산이 둘 다 M of N을 구현하지만 그 특성이 약간 다르기 때문에 적합한 용처도 다르다고 생각한다. 만약 한 기업이 여러 이사진의 의사결정 과정에서 권한을 분산해야 한다면 멀티시그 방식이 훨씬 나을 것이다. 이사 각각이 서명하면 되기 때문이다. 여기다가 샤미르 분산을 쓴다면 이사 몇 명이 모여 키 하나를 생성했을 때 쪼개기 전의 원래 하나의 키가 생기므로 권한 분산에 차질이 생길 수 있다. 그 키를 갖는 사람이 갑자기 모든 권한을 가질 수 있게 되기 때문이다. 거꾸로 한 개인이 키를 백업하고자 하는데 키를 분실하거나 화재나 기타 재난 등의 이유로 파괴될 것에 대비하여 여러 장소에 분산하여 보관하고 싶다면 샤미르 분산이 더 적합할 것이다. 키 조각들을 합쳐서 원래 키가 생겼을 때 그 키는 어차피 한 개인이 쓰는 것이므로 권한 구조가 갑자기 한 곳으로 몰리는 것에 대해 걱정할 필요가 없기 때문이다.
그런데 샤미르 분산은 멀티시그보다 직관적이진 않은 것 같다. 멀티시그는 스크립트 구조를 보면 바로 어떤 구조인지 알 수 있다. 손으로 따라 쓸 수도 있는 수준이다. 하지만 트레저가 도입한 샤미르 분산인 SLIP-0039 같은 형식은 직관적이지가 않다. 일단 샤미르 분산이 다항함수를 통한 비밀 분산을 쓰는 원리라는 걸 이해해야 하고(키 조각이 부족하면 부정방정식이 되어서 복구 불가), 그걸 통해 복구하는 과정에서 사용하는 라그랑주 보간법이 인간이 손으로 계산하기에는 너무 어렵다. 키를 분할하고 복구하는 과정이 수학적인 함수 공간에서 정의되고, 사용자는 키 조각들만 보게 되므로 내부 구조에 대해 직관적으로 이해하기가 어렵다.
오프라인 손 계산과 직관적 이해
조금 다른 주제로 넘어가보자. 나는 기술의 사용자들이 그 기술을 '직관'적으로 이해할 수 있는 지가 매우 중요하다고 생각한다. 비트코인 경험에는 특히 '검증'이 중요한데 어떤 기술을 직관적으로 이해할 수 없다면 검증은 전문가들만의 전유물이 되기 때문이다.
예를 들어보자. 앨리스, 밥, 캐롤이 각각 니모닉을 만들었다.
1. 앨리스는 기계가 생성해준 니모닉을 사용한다. 기계는 SE칩 내부에 있는 전자의 브라운 운동 등을 엔트로피로 이용해 랜덤한 엔트로피를 생성했다. 하지만 앨리스는 이 사실을 모르고, 따라서 기계를 신뢰해야 한다. 앨리스는 기계가 생성해 준 엔트로피가 충분히 랜덤하고 안전하다고 "믿고 있다." 사실이 그런지 아닌지와는 별개로 말이다.
2. 밥은 주사위를 던져서 만든 니모닉을 사용한다. 하지만 주사위를 던졌을 때 나온 값이 어떻게 니모닉으로 변환되는지는 모른다. 기계는 주사위를 던져 나온 숫자를 유니코드 문자열로 인식하여 SHA256을 한 번 돌린 뒤, 그 해시값을 엔트로피로 사용한다. 밥은 자신이 직접 주사위를 던졌으므로 엔트로피가 랜덤하게 생성되었다는 것은 직관적으로 알지만, 그 숫자가 어떻게 니모닉으로 계산된 건지는 모른다.
3. 캐롤은 직접 동전을 던져 0, 1을 기록하고 자신이 직접 니모닉 표를 보며 니모닉을 대응시켰다. 따라서 캐롤은 자신이 사용하는 니모닉이 랜덤하다는 것도 이해하고 있으며, 랜덤한 엔트로피를 어떻게 니모닉에 대응시키는지도 알고 있다.
세 가지 경우 중 누가 니모닉에 대해 가장 잘 직관적으로 이해하고 있겠는가? 당연히 3번 캐롤이다. 이렇듯 오프라인에서 동전을 던져 직접 엔트로피를 생성하고, 표를 보며 손으로 직접 니모닉에 대응시키는 과정은 니모닉을 직관적으로 이해하는 데 매우 중요하다.
솔직히 3번의 경우도 완전히 신뢰 지점이 없진 않다. 왜냐하면... 니모닉의 체크썸을 계산하는 과정에서 해싱을 해야 하기 때문이다. 손으로 SHA256 함수를 계산할 수 있는 게 아니라면... 캐롤은 어떤 기계에게 체크섬 생성을 맡길 수밖에 없다. 그러면 적어도 그 과정에 대한 이해의 폭은 제한될 수밖에 없다.
오프라인에서 계산하는 경험들이 왜 직관적인 이해에 더 도움이 될까? 그 과정들을 자신이 온전히 통제하기 때문이다. 기계에 맡겨야 하는 순간에는 그 기계 안에서 무엇이 일어나는지 알 수 없으며 따라서 자신의 통제 밖에 있다.
펜락 프로젝트
서론이 길었다! 다시 샤미르 분산 이야기로 돌아오겠다. 샤미르 분산을 '손으로 계산'해 키 조각을 만들고, 키 조각들을 모아 다시 오프라인에서 '손으로 계산'해 하나로 만들 수 있을까? 거의 불가능에 가까울 것이다!
그런데 이번에 BSL 컨퍼런스에서 펜락 프로젝트에 참여하고 있는 한 분을 우연히 만나 인사를 나눴고, 며칠 뒤 있는 비트코인 서울 컨퍼런스에서 그 분이 나한테 선물을 주셨다. 바로... 아래 사진의 회전판이다. 직접 가위로 자르고 핀을 꽂는 것까지 봤다(컨퍼런스 강연 중에 뒷자리에서 가위로 자르고 있어서 웃음을 참을 수가 없었다ㅋㅋㅋ). 나는 이 귀엽고 조악한 회전판을 처음 봤을 때 이 위력에 대해 알지 못했다...
이 펜락 프로젝트 회전판은... 샤미르 분산처럼 하나의 키를 키 조각으로 나누고, 그 키 조각들을 오프라인에서 원래 키로 복구할 수 있게 만들어준다. 이게 작동하는 걸 처음 봤을 때 나는 정말 정말 x21 엄청나게 놀랐다.
사용 방법을 간단히 말해보자면, 메인 키(니모닉)가 있으면 니모닉 한 단어의 앞 4개 문자만 적는다(이유는 다들 아실 거라 생각... 니모닉은 앞 4글자가 겹치는 경우가 없기 때문). 그 다음에 두 숫자를 뽑는다. 1–32까지의 숫자 한 장, 그리고 1–32까지의 숫자인데 흰 동그라미/검은 동그라미 나눠져있는 걸로 한 장(그러면 총 64가지 경우일 것이다). 그러면 32*64 = 2,048가지 경우가 나온다. 그리고 체크섬을 표에서 찾아 적는데, 솔직히 추가 체크썸이 왜 필요한 건지는 아직 이해를 못했다. 진짜로 이 오프라인 과정을 해보며 생길 수 있는 오류를 잡기 위한 체크썸인 것으로 이해된다.
어쨌든 하이라이트는 지금부터인데... 자, 니모닉에서 'F'라는 단어가 있다고 해보자. 그러면 아래 사진처럼 눈금을 F에다 둔다. 그 다음 랜덤한 숫자를 뽑는다. 그렇게 뽑은 숫자가 22이라고 해보자. 그러면 회전판 내부에서 22, 23, 24에 있는 문자를 각각 아래에 적는다. 이게 키 조각이다... F가 ① V, ② P, ③ J 이렇게 세 가지 조각으로 분할 된 거다.
이제 세 개의 키 조각 ① V, ② P, ③ J로 키를 복구하는 상황을 생각해보자. 만약 ③번 키 조각인 J가 화재로 날아가버렸다. 2 of 3이니 그래도 키 조각이 두 개만 있어도 복구할 수 있다. ①번 키 조각인 V와, ②번 키 조각인 P를 조합해 키를 복구해보겠다. 그러면 회전판을 움직여... P가 V를 바라보게 하면 된다. 사진에서 빨간 박스로 표시한 부분이다. 그러면 큰 눈금이 원래 키인 F를 가리키게 된다. 정말 미쳤다! 만약, ②번 키 조각 P와, ③번 키 조각 J가 있다면 J가 P를 바라보게 하면 된다. 만약 ③번 키 조각 J와, ①번 키 조각 V로 키 복구를 시도한다면 J가 V를 바라보게 하고, 대신 ③번이 ①번을 바라보게 하는 것처럼 순환하는 상황에는 큰 눈금이 아니라 내부 1번 네모칸을 읽어야 한다.
펜락 회전판의 뒷면을 보면 이걸 어떻게 구현했는지 대강 알 수가 있다. 펜락 프로젝트는 반지름을 조금씩 다르게 하고, 회전 각도를 서로소인 두 숫자를 이용해 글자들이 겹치지 않도록 구현한 걸로 보인다. 말로 설명했지만, 직접 해봐야 "미쳤다!" 소리가 저절로 나온다. 이거 직접 해보면 ~비속어가 나올 정도로~ 놀란다. 정말로.
펜락 프로젝트는 오픈 소스라고 하고, 최고 개발자는 ganrama이다(사이트는 아직 베타라서 내용들이 채워지고 있는 걸로 보인다ㅎㅎ).
https://github.com/ganrama
https://beta.penlock.io/
나는 비트코인에서 나오는 프로젝트들을 일단 의심부터 하고 보는 편이다. 그런데 펜락은 직관적으로 다 이해가 되기 때문에 현재는 우려할만한 점이 생각나지 않는다. 비트코인 프로젝트들 중에는 편리함, 보안, 프라이버시 중 무언가를 희생시키고 그걸 교묘히 감추려고 하거나 비즈니스 모델을 만들다가 초기의 정신을 잊는 경우가 많다. 그런데 이 프로젝트는 그에 해당할 만한 게 없는 것 같아서 일단 의심의 눈초리를 거두고 응원한다. 내가 오프라인에서 직접 키를 분할해보고, 조합해본 경험이 너무 강렬하게 작용했기 때문인 것 같다. 펜락 대표 개발자가 올해 하반기에 기회가 된다면 한국에서도 소개하고 싶다고 하니 계속 관심을 갖고 지켜보려고 한다.

2025-06-17 17:51:52Com a crescente digitalização do dinheiro, os governos de vários países começaram a desenvolver moedas digitais de banco central (CBDCs - Central Bank Digital Currencies) como resposta à popularização de Bitcoin. Enquanto Bitcoin representa um sistema financeiro descentralizado e resistente à censura, as CBDCs são versões digitais das moedas fiduciárias, controladas diretamente pelos bancos centrais. Essa concorrência pode moldar o futuro do dinheiro e definir o equilíbrio entre liberdade financeira e controlo estatal.
Diferenças fundamentais entre Bitcoin e CBDCs
Bitcoin e as CBDCs diferem em praticamente todos os aspetos fundamentais:
Centralização vs. Descentralização: Bitcoin opera numa rede descentralizada, onde nenhum governo ou entidade pode alterar as regras ou censurar transações. Já as CBDCs são emitidas e controladas pelos bancos centrais, permitindo um maior controlo sobre a circulação e utilização do dinheiro.
Oferta limitada vs. Inflação controlada: Bitcoin tem uma oferta fixa de 21 milhões de unidades, tornando-se um ativo escasso e deflacionário. As CBDCs, por outro lado, podem ser criadas sem limites, como acontece com as moedas fiduciárias tradicionais, sujeitas a políticas monetárias inflacionárias.
Privacidade vs. Monitorização: Bitcoin permite transações pseudónimas, garantindo um certo nível de privacidade financeira. As CBDCs, no entanto, podem ser programadas para permitir o rastreamento total de cada transação, facilitando a supervisão governamental e, potencialmente, o controlo sobre o que os cidadãos podem ou não gastar.
Resistência à censura vs. Controlo estatal: Bitcoin permite que qualquer pessoa realize transações sem depender de aprovação de terceiros. As CBDCs, por serem centralizadas, podem ser usadas pelos governos para restringir transações indesejadas ou mesmo confiscar fundos com um simples comando digital.
O que os governos pretendem com as CBDCs?
A introdução das CBDCs tem sido vendida com argumentos como:
Maior eficiência nas transações financeiras, eliminando intermediários e reduzindo custos bancários.
Facilidade na implementação de políticas económicas, como estímulos diretos à população ou tributação automatizada.
Combate a atividades ilegais, dado que as transações podem ser rastreadas em tempo real.
No entanto, muitas destas justificações levantam preocupações sobre a perda de privacidade financeira e o aumento do poder dos governos sobre o sistema monetário.
Bitcoin como alternativa às CBDCs
A ascensão das CBDCs pode fortalecer a posição de Bitcoin como alternativa de dinheiro verdadeiramente livre. À medida que os cidadãos percebem os riscos de um sistema financeiro 100% controlado pelo Estado, a procura por um ativo descentralizado e resistente à censura pode crescer.
Proteção contra o controlo estatal: Bitcoin permite que os utilizadores mantenham total soberania sobre o seu dinheiro, sem o risco de bloqueios arbitrários ou confiscações.
Preservação da privacidade financeira: Ao contrário das CBDCs, que podem monitorizar todas as transações, Bitcoin oferece um grau de anonimato que protege os indivíduos da vigilância excessiva.
Reserva de valor contra a inflação: Enquanto os governos podem emitir CBDCs indefinidamente, Bitcoin mantém a sua escassez garantida, tornando-se um refúgio contra políticas monetárias irresponsáveis.
Resumindo, a competição entre Bitcoin e as CBDCs será uma das maiores batalhas financeiras do futuro. Enquanto os governos tentam consolidar o seu controlo através de moedas digitais centralizadas, Bitcoin continua a ser a principal alternativa para aqueles que procuram independência financeira e proteção contra a vigilância estatal. A escolha entre um sistema financeiro livre e um sistema monitorizado e controlado poderá definir o rumo da economia digital nas próximas décadas.
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 16:40:13After 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.
What's Next?
This is just the beginning. We will be constantly working to improve KYCnot.me and add more features that help you preserve your privacy.
Remember: True financial freedom requires the right to privacy. Stay KYC-free!

2025-06-17 17:49:53Desde a sua criação, Bitcoin tem sido um ativo revolucionário, desafiando o sistema financeiro tradicional e propondo uma nova forma de dinheiro descentralizado. No entanto, o seu futuro ainda é incerto e gera intensos debates. Entre os cenários possíveis, dois extremos destacam-se: a hiperbitcoinização, onde Bitcoin se torna a moeda dominante na economia global, ou a obsolescência, caso a rede perca relevância e seja substituída por outras soluções.
Hiperbitcoinização: o mundo adota Bitcoin como padrão monetário
Perda de confiança nas moedas fiduciárias: Com a impressão excessiva de dinheiro por bancos centrais, muitas economias enfrentam inflação descontrolada. Bitcoin, com a sua oferta limitada de 21 milhões de unidades, apresenta-se como uma alternativa mais confiável.
Adoção crescente por empresas e governos: Alguns países já começaram a integrar Bitcoin na sua economia, aceitando-o para pagamentos e reserva de valor. Se essa tendência continuar, a legitimidade de Bitcoin como moeda global aumentará.
Facilidade de transações globais: Bitcoin permite transferências internacionais rápidas e baratas, eliminando a necessidade de intermediários financeiros e reduzindo custos operacionais.
Avanços tecnológicos: Melhorias na escalabilidade, como a Lightning Network, podem tornar Bitcoin mais eficiente para uso diário, facilitando sua adoção em massa.
Se a hiperbitcoinização acontecer, o mundo pode testemunhar uma mudança radical no sistema financeiro, com maior descentralização, resistência à censura e uma economia baseada em dinheiro sólido e previsível.
Obsolescência: Bitcoin perde relevância e É substituído
Regulações governamentais restritivas: Se grandes potências económicas impuserem regulações severas sobre Bitcoin, a adoção pode ser dificultada, reduzindo sua utilidade.
Falhas tecnológicas ou falta de inovação: Apesar da sua segurança e descentralização, Bitcoin pode enfrentar dificuldades para escalar de forma eficiente. Se soluções melhores surgirem e forem amplamente aceites, Bitcoin pode perder a sua posição de liderança.
Concorrência com alternativas mais rápidas e eficientes: Se outras formas de dinheiro digital conseguirem superar Bitcoin em termos de escalabilidade e usabilidade, a rede pode ver a sua adoção diminuir.
Falta de incentivos para os mineradores: Como a emissão de novos Bitcoins diminui a cada halving, os mineradores dependerão cada vez mais das taxas de transação. Se essas taxas não forem suficientes para sustentar a segurança da rede, pode haver um risco para a sua viabilidade a longo prazo.
Resumindo, o futuro do Bitcoin pode seguir diferentes caminhos, dependendo de fatores como inovação, adoção global e resistência a desafios externos. A hiperbitcoinização representaria uma revolução económica, com um sistema monetário descentralizado e resistente à inflação. No entanto, a obsolescência continua a ser um risco, caso a rede não consiga adaptar-se às exigências futuras. Independentemente do desfecho, Bitcoin já deixou a sua marca na história financeira, abrindo caminho para uma nova era de dinheiro digital e liberdade económica.

Version 1.3 of Bitcoin Safe introduces a redesigned interactive chart, quick receive feature, updated icons, a mempool preview window, support for Child Pays For Parent (CPFP) and testnet4, preconfigured testnet demo wallets, as well as various bug fixes and improvements.
-
Upcoming updates for Bitcoin Safe include Compact Block Filters.
"Compact Block Filters increase the network privacy dramatically, since you're not asking an electrum server to give you your transactions. They are a little slower than electrum servers. For a savings wallet like Bitcoin Safe this should be OK," writes the project's developer Andreas Griffin.

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.

Transações globais e sem fronteiras: Qualquer pessoa com acesso à internet pode enviar e receber Bitcoin sem precisar de um banco ou autorização governamental.
Oferta limitada e previsível: Ao contrário do dinheiro fiduciário, que pode ser inflacionado por bancos centrais, Bitcoin tem um limite fixo de 21 milhões de unidades, tornando-o um ativo escasso e confiável.
Segurança e transparência: A blockchain ou timechain de Bitcoin regista todas as transações publicamente, garantindo um sistema seguro e auditável.
Resistência à censura: Nenhum governo ou entidade pode bloquear transações de Bitcoin, permitindo uma economia digital mais livre e acessível.
Com essas características, Bitcoin já está a transformar diversos setores económicos, impulsionando novas formas de comércio e investimento.
Bitcoin no comércio digital e na economia global
E-commerce: Empresas e consumidores podem utilizar Bitcoin para transações internacionais rápidas e sem taxas abusivas.
Remessas internacionais: Trabalhadores que enviam dinheiro para os seus países de origem podem evitar taxas elevadas e transferências demoradas ao utilizar Bitcoin.
Economias emergentes: Em países com moedas instáveis e sistemas bancários pouco confiáveis, Bitcoin serve como uma alternativa segura e descentralizada para armazenamento de riqueza e transações diárias.
Além disso, Bitcoin está a ser adotado por empresas e governos como reserva de valor, reforçando o seu papel como base para a economia digital do futuro.
Desafios e adaptação à nova economia
Volatilidade do preço: A oscilação do valor de Bitcoin pode dificultar o seu uso diário como meio de pagamento.
Regulações e resistência governamental: Alguns países tentam limitar ou regular Bitcoin para manter o controlo sobre o sistema financeiro tradicional.
Educação e adoção: Muitas pessoas ainda desconhecem como utilizar Bitcoin de forma segura e eficiente.
Resumindo, o Bitcoin está a transformar a forma como o mundo interage com o dinheiro, oferecendo uma alternativa descentralizada e transparente para economias digitais.

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.

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.

2025-06-15 07:01:57The 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 16:01:54Japanese 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.”

2025-06-17 17:46:15Desde a sua criação, Bitcoin tem sido um marco na revolução do dinheiro digital, mas a sua evolução não parou no conceito inicial de transações descentralizadas. Ao longo dos anos, novas soluções tecnológicas foram desenvolvidas para expandir as suas capacidades, tornando-o mais eficiente e versátil. Entre essas inovações, destacam-se os smart contracts e a Lightning Network, que permitem aumentar a funcionalidade e escalabilidade da rede, garantindo um sistema mais rápido, barato e acessível.
Smart contracts no Bitcoin
Os smart contracts (contratos inteligentes) são programas que executam automaticamente determinadas ações quando certas condições pré-definidas são cumpridas. Embora o conceito seja mais comummente associado a outras redes, Bitcoin também suporta contratos inteligentes, especialmente através de atualizações como o Taproot.
Os smart contracts em Bitcoin permitem funcionalidades como:
Pagamentos condicionais: Transações que só são concluídas se determinadas regras forem cumpridas, como assinaturas múltiplas ou prazos específicos.
Gestão avançada de fundos: Utilização de carteiras multi-assinatura, onde diferentes partes precisam aprovar uma transação antes de ser processada.
Maior privacidade: Com a atualização Taproot, os smart contracts podem ser mais eficientes e indistinguíveis das transações normais, melhorando a privacidade da rede.
Embora os contratos inteligentes em Bitcoin sejam mais simples do que em outras redes, essa simplicidade é uma vantagem, pois mantém a segurança e robustez da rede, evitando vulnerabilidades complexas.
Lightning Network: escalabilidade e transações instantâneas
Um dos maiores desafios enfrentados por Bitcoin é a escalabilidade. Como a rede original foi desenhada para priorizar segurança e descentralização, a velocidade das transações pode ser limitada em períodos de alta procura. Para resolver esse problema, foi criada a Lightning Network, uma solução de segunda camada que permite transações quase instantâneas e com taxas extremamente baixas.
A Lightning Network funciona criando canais de pagamento entre utilizadores, permitindo que realizem várias transações fora da blockchain ou timechain principal de Bitcoin, registando apenas o saldo final na rede principal. Algumas vantagens incluem:
Velocidade: Transações são concluídas em milissegundos, tornando Bitcoin mais adequado para pagamentos diários.
Taxas baixas: Como as transações ocorrem fora da blockchain ou timechain principal, as taxas são mínimas, permitindo microtransações viáveis.
Descongestionamento da rede: Ao transferir grande parte das transações para a Lightning Network, a rede principal de Bitcoin torna-se mais eficiente e menos sobrecarregada.
Resumindo, o Bitcoin continua a evoluir tecnologicamente para se adaptar às necessidades de um sistema financeiro global. Os smart contracts aumentam as suas funcionalidades, permitindo maior flexibilidade e segurança nas transações. A Lightning Network melhora a escalabilidade, tornando Bitcoin mais rápido e eficiente para pagamentos do dia a dia. Com estas inovações, Bitcoin mantém-se na vanguarda da revolução financeira, demonstrando que, apesar das limitações iniciais, continua a adaptar-se e a crescer como um sistema monetário verdadeiramente descentralizado e global.

2025-06-15 00:36:391. Introduction
The 21st century is marked by a rare confluence of demographic, technological, and monetary regime shifts. As birth rates fall below replacement levels across advanced and many emerging economies, global population growth slows and begins to reverse. At the same time, automation, AI, and robotics are increasing productivity at an accelerating pace. Simultaneously, trust in central banks and fiat currencies is waning, giving rise to calls for a return to hard currencies (e.g., gold, Bitcoin) and decentralized monetary systems.
These trends pose stark challenges to existing economic theories and institutions. This paper explores their implications through two opposing lenses: Keynesian economics and Austrian (Misesian) economics.
2. The Keynesian Reaction: Deflation, Demand Collapse, and the Paradox of Thrift
2.1. Demand-Side Fragility in a Shrinking Population
Keynesian theory is rooted in the principle that aggregate demand drives output and employment. A declining population implies a falling consumption base, which directly reduces aggregate demand. Combined with increased longevity, this trend leads to a larger retired population disinclined to spend, creating persistent demand shortfalls.
2.2. Technological Unemployment and Reduced Income Velocity
Rapid productivity gains from AI and robotics may displace large segments of labor, leading to unemployment or underemployment. With fewer wage earners and heightened uncertainty, consumption slows further. Even if goods become cheaper, widespread income insecurity constrains the ability to buy them.
2.3. The Paradox of Thrift
In times of uncertainty, both individuals and businesses tend to save more. Keynes argued that if everyone saves, aggregate demand collapses because one person’s spending is another’s income. Thus, increased saving leads to lower incomes, which reduces saving in aggregate—a self-reinforcing contraction.
2.4. Retreat from Fiat and Central Banking: A Catastrophic Constraint
Abandoning fiat currency and central banking removes the government’s ability to perform countercyclical policy. Interest rates cannot be lowered below zero; money supply cannot be expanded to fill demand gaps. In such a regime, deflation becomes chronic, debt burdens rise in real terms, and recovery mechanisms are neutered.
Conclusion (Keynesian):
The combined effect of declining population, rising productivity, and a hard money transition is catastrophic. It leads to a deflationary spiral, mass unemployment, debt crises, and secular stagnation unless aggressively offset by expansive fiscal and monetary policy—tools unavailable in a hard currency system.
3. The Misesian Rebuttal: Market Coordination and the Natural Order of Decline
3.1. Savings as Capital Formation
Mises and the Austrian School reject the paradox of thrift. Savings are not lost demand; they are deferred consumption that funds capital investment. Increased saving, in a free market, lowers interest rates and reallocates resources toward longer-term, higher-order production.
3.2. Deflation as a Signal of Progress
Falling prices due to productivity gains are not a crisis but a benefit. Consumers gain real wealth. Entrepreneurs adjust cost structures. As long as wages and prices are flexible, deflation reflects abundance, not failure.
3.3. Population Decline as Economic Recalibration
A shrinking population reduces demand, yes—but it also reduces the labor supply. Wages rise in real terms. Capital intensity per worker increases. There is no systemic unemployment if labor markets are free and responsive.
3.4. Hard Currency as Restoration of Market Coordination
Transitioning to a hard currency purges fiat-induced malinvestment and restores the price mechanism. With no artificial credit expansion, capital is allocated based on real savings. Booms and busts are mitigated, and long-term planning becomes reliable.
Conclusion (Misesian):
There is no crisis. A hard currency, high-productivity, low-population economy stabilizes at a new equilibrium of lower consumption, higher capital intensity, and rising real wealth. Deflation is natural. Savings are the seed of future prosperity. Government interference, not market adaptation, is the threat.
4. Final Synthesis
The Keynesian and Misesian views diverge on first principles: Keynes sees demand shortfalls and rigidities requiring top-down correction, while Mises sees market-coordinated adaptation as sufficient and self-correcting. As the 21st century evolves, this ideological conflict will shape whether the transition leads to depression or renewal.

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.

2025-06-17 17:44:37Ao longo da história, o dinheiro sempre esteve sob o controlo de autoridades centrais, como governos e bancos. Estes intermediários determinaram as regras do sistema financeiro, controlaram a emissão de moeda e supervisionaram transações. No entanto, com o surgimento de Bitcoin, um novo paradigma começou a emergir: o dinheiro descentralizado. Esta transformação representa uma mudança profunda na forma como as pessoas armazenam e transferem valor, desafiando o modelo tradicional de finanças.
O modelo tradicional: dinheiro centralizado
Dependência de intermediários: Para realizar transações, as pessoas dependem de bancos, governos e outras entidades reguladoras.
Inflação e desvalorização: Os bancos centrais podem imprimir dinheiro de forma ilimitada, o que frequentemente leva à perda do poder de compra da moeda.
Censura e restrições: O acesso ao dinheiro pode ser negado por motivos políticos, burocráticos ou institucionais, limitando a liberdade financeira dos indivíduos.
Apesar de ter sido o modelo dominante durante séculos, o sistema centralizado mostrou as suas fragilidades em diversas crises económicas e políticas. Foi neste contexto que Bitcoin surgiu como uma alternativa inovadora.
A revolução do dinheiro descentralizado
Eliminação de intermediários: As transações podem ser feitas diretamente entre utilizadores, sem necessidade de bancos ou empresas financeiras.
Oferta limitada e previsível: Bitcoin tem um limite fixo de 21 milhões de unidades, evitando a inflação causada pela impressão excessiva de moeda.
Resistência à censura: Nenhuma entidade pode bloquear ou impedir transações, garantindo total liberdade financeira.
Autocustódia: Cada utilizador pode guardar os seus próprios fundos sem depender de um banco ou qualquer outra instituição.
Esta mudança de paradigma tem um impacto significativo não apenas no sistema financeiro, mas também na forma como as pessoas interagem com o dinheiro e protegem o seu património.
Desafios e oposição à descentralização financeira
A transição para um sistema financeiro descentralizado enfrenta vários desafios, sendo o principal a resistência por parte das instituições tradicionais. Bancos e governos veem Bitcoin como uma ameaça ao seu controlo sobre o dinheiro e procuram regular ou limitar a sua adoção.
Além disso, ainda existem barreiras técnicas e educacionais. Muitas pessoas não compreendem completamente como funciona Bitcoin, o que pode dificultar a sua adoção. No entanto, à medida que mais pessoas tomam consciência dos benefícios do dinheiro descentralizado, a sua utilização tende a crescer.
Resumindo, a mudança de um sistema financeiro centralizado para um descentralizado representa uma das transformações mais importantes da era digital. Bitcoin lidera este movimento, oferecendo uma alternativa resistente à censura, transparente e acessível. Apesar da oposição do sistema tradicional, a descentralização do dinheiro continua a ganhar força, proporcionando mais autonomia e liberdade financeira às pessoas em todo o mundo. Esta revolução não é apenas tecnológica, mas também social e económica, redefinindo a forma como o mundo entende e utiliza o dinheiro.
