2025-06-17 15:55:26O Bitcoin tem se destacado como uma ferramenta econômica nova em economias em desenvolvimento. Essas nações muitas vezes enfrentam dificuldades como alta inflação, sistemas bancários frágeis e acesso restrito a serviços financeiros. Com suas características especiais, como descentralização, resistência à censura e oferta limitada, o Bitcoin aparece como uma solução alternativo para proteger patrimônio, facilitar transações internacionais e promover a inclusão financeira.
Desafios enfrentados por economias emergentes
Inflação e desvalorização da moeda:
Muitos países em desenvolvimento enfrentam políticas monetárias instáveis, levando à desvalorização de suas moedas.
A inflação diminui o poder de compra das pessoas, tornando difícil manter patrimônio e planejar finanças a longo prazo.
Acesso dimitado ao sistema bancário:
Em várias áreas, especialmente rurais, uma parte significativa da população não tem acesso a bancos ou serviços financeiros básicos.
Isso dificulta a guarda de dinheiro, a obtenção de crédito e a realização de transações seguras.
Remessas e transações internacionais caras:
Muitos cidadãos de economias em desenvolvimento dependem de remessas enviadas por familiares que trabalham no exterior.
As taxas cobradas por intermediários financeiros podem ser elevadas, diminuindo o valor recebido pelas famílias.
Como o Bitcoin beneficia economias emergentes
Proteção contra inflação:
Com sua oferta limitada a 21 milhões de unidades, o Bitcoin serve como um ativo deflacionário, permitindo que indivíduos protejam seu patrimônio contra a desvalorização da moeda local.
Em países como Venezuela e Argentina, onde as taxas de inflação são muito altas, o Bitcoin tem sido usado como uma reserva de valor.
Inclusão financeira:
O Bitcoin elimina a necessidade de intermediários financeiros, permitindo que qualquer pessoa com acesso à internet participe da economia global.
Indivíduos sem conta bancária podem usar carteiras digitais para guardar e transacionar valor, promovendo a inclusão financeira em larga escala.

Isso ajuda trabalhadores que enviam dinheiro para casa, garantindo que mais recursos cheguem aos destinatários finais.
Resistência à censura e controle governamental:
Em economias em desenvolvimento com governos autoritários ou instabilidade política, o Bitcoin permite que cidadãos mantenham controle sobre seu dinheiro, sem medo de confiscos ou restrições injustas.
Sua rede descentralizada impede que uma única autoridade controle ou manipule o sistema.
Casos reais de uso em economias emergentes
El Salvador:
Em 2021, El Salvador se tornou o primeiro país a tornar o Bitcoin uma moeda oficial. Essa escolha tinha o objetivo de diminuir os custos das remessas internacionais e aumentar a inclusão financeira.
A iniciativa também atraiu investimentos e turismo ligados ao Bitcoin, embora enfrente críticas e dificuldades de implementação.
Nigéria:
Na Nigéria, o uso do Bitcoin aumentou bastante devido à inflação e às restrições do governo sobre transações financeiras.
Jovens empreendedores e trabalhadores autônomos usam o Bitcoin para receber pagamentos internacionais e evitar limitações impostas por bancos locais.
Venezuela:
Com a crise econômica e a hiperinflação, o Bitcoin se tornou uma ferramenta importante para proteger a riqueza e fazer transações no país.
Muitas famílias venezuelanas dependem do Bitcoin para comprar produtos essenciais e enviar ou receber dinheiro do exterior.
Desafios do uso de Bitcoin em economias emergentes
Volatilidade:
A alta volatilidade no preço do Bitcoin pode fazer com que seu uso seja arriscado para pessoas que dependem dele como reserva de valor.
Essa instabilidade pode desestimular seu uso em transações do dia a dia.
Infraestrutura Limitada:
O uso do Bitcoin precisa de acesso à internet e dispositivos digitais, o que pode ser um impedimento em áreas com infraestrutura limitada.
Educação e Adaptação:
A adoção do Bitcoin requer um certo nível de conhecimento técnico, e a falta de educação financeira pode dificultar sua utilização em larga escala.
Muitas pessoas ainda preferem moedas tradicionais por falta de conhecimento ou desconfiança em relação ao Bitcoin.

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

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

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

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

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

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

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

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

Strategy Acquires 10,100 BTC, Surpasses 592,000 Bitcoin in HoldingsMichael Saylor’s Strategy announces it has purchased an additional 10,100 BTC for approximately $1.05 billion, raising its total holdings to 592,100 BTC acquired at an average cost of $70,666 per Bitcoin.
BREAKING:
STRATEGY BUYS ANOTHER 10,100 #BITCOIN pic.twitter.com/TZ6nosWenr
— Bitcoin Magazine (@BitcoinMagazine) June 16, 2025
Strategy added another 10,100 Bitcoin to its treasury between June 9 and June 15, 2025, according to a Form 8-K filed Monday with the SEC. The company spent approximately $1.05 billion on the latest allocation, paying an average price of $104,080 per Bitcoin, inclusive of fees and expenses.
This brings Strategy’s total holdings to 592,100 BTC, acquired at a cumulative cost of $41.84 billion, or an average price of $70,666 per Bitcoin, solidifying its status as the world’s largest corporate holder of Bitcoin.
The recent allocation was financed through multiple capital raises. Strategy tapped its STRK and STRF at-the-market offerings, and completed a $979.7 million public offering of STRD, its 10.00% Series A Perpetual Stride Preferred Stock, on June 10.
“The Bitcoin purchases were made using proceeds from the STRK ATM, STRF ATM, and STRD Offering,” the company stated.
In addition to the purchase, Strategy reported a 19.1% BTC yield year-to-date in 2025, reflecting the strength of its long-term bitcoin investment thesis.
This latest acquisition follows a series of steady purchases throughout 2024 and early 2025. Strategy has continued to scale its position quarter over quarter, using capital market tools to accumulate Bitcoin as part of its strategy.
“Strategy continues to execute on its commitment to the Bitcoin standard,” the company stated in its filing.
The company continues to emphasize transparency around its holdings. Its website, strategy.com, hosts a Bitcoin Dashboard that is regularly updated with BTC purchase details, securities activity, and performance metrics in compliance with Regulation FD.
Strategy’s move comes during increasing institutional adoption of Bitcoin in 2025. The company’s acquisition strategy and consistent messaging have made it a leader for corporate engagement with the digital asset.
With its most recent buy, Strategy now holds over 592,000 Bitcoin, a significant portion of the asset’s fixed 21 million supply—showing its view of Bitcoin not just as an investment, but as a core component of its financial strategy.

@ 39cc53c9:27168656
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!

Ethereum 0.0039 ETH (zkSync) “39” sounds like “thank you” in Japanese. Prices aren’t pegged to yen.These days I’m open only once a week. On other days I’m out scouting new spots for the kitchen-car. If you know weekday-lunch locations inside Tokyo where I could set up, please let me know!
The photo shows an NFC tag. If your phone has a Lightning wallet, just tap and pay 3,900 sats. I admit this hand-written NFC tag looks shady—any self-respecting Bitcoiner probably wouldn’t want to tap it—but the point is: even this works!
I used to run a BTCPay POS, but I switched to this setup for speed. Sometimes the tap payment fails; if that happens I reluctantly pull out the old POS. Thanks for your patience.
It’s been one year since I spun up a node and started accepting Lightning payments. So many people are now running their own nodes—Umbrel really is amazing. While the big players bravely chase routing fees, I’m a tiny operator scraping together funds while begging my wife for forgiveness, so I’m all-in on maximising payment convenience. Your support means a lot!
If I may add: routing is fun, but instant, trust-minimised payments and the thrill of choosing whom to open channels with are just as exciting. You’ll only understand once you start accepting payments yourself—zero-confirmation settlement really is revolutionary.
QR codes, NFC taps, fixed amounts, manual entry… the possibilities keep multiplying, and the pace of innovation is scary fast. When I compare it to the merchant fees on Japan’s most-used service, PayPay, I want to shout: “Bitcoin is incredible!” Sure, taxes, price volatility (my shop is BTC-denominated, though), wallet UX, and adoption hurdles are still pain points.
Even so, lots of people keep building cool stuff, so I’ll keep doing what I can—still on my knees to my wife, but moving forward!

2025-06-17 14:59:12Bitcoin é a primeira moeda digital descentralizada do mundo, criada em 2009 por um indivíduo ou grupo sob o pseudônimo de Satoshi Nakamoto. O seu nascimento marcou o início de uma revolução no sistema financeiro global, introduzindo um novo tipo de moeda que não é controlada pelos governos ou instituições financeiras tradicionais. A história do Bitcoin está profundamente enraizada nos ideais de liberdade económica, transparência e resistência à censura.
A jornada começou em outubro de 2008, quando Satoshi Nakamoto publicou um artigo intitulado “Bitcoin: A Peer-to-Peer Electronic Cash System”. O white paper, publicado na mailing list Cryptozoology, descreve a ideia de um sistema de pagamento digital baseado em uma rede peer-to-peer. Esse conceito elimina a necessidade de intermediários como bancos e resolve um problema conhecido como “gasto duplo” – possibilidade de replicação de moedas digitais – por meio de uma tecnologia chamada blockchain ou aquilo que o próprio Satoshi Nakamoto chamava de timechain.
O blockchain ou timechain é basicamente um livro-razão público e imutável que registra todas as transações do Bitcoin. Opera através de um sistema descentralizado, onde os participantes da rede (os chamados nós ou famosos nodes) verificam as transações e as organizam em blocos. Esses blocos são conectados por sua vez em uma cadeia contínua, formando a base para a segurança e transparência do sistema.
No dia 3 de janeiro de 2009, Satoshi Nakamoto extraiu o primeiro bloco do Bitcoin, conhecido como bloco gênese. O bloco continha uma mensagem codificada referenciando a crise financeira global de 2008: "The Times, 3 de janeiro de 2009, Chanceler à beira do segundo resgate bancário". Esta mensagem é emblemática da motivação por trás do Bitcoin: fornecer uma alternativa ao sistema financeiro centralizado que não conseguiu proteger a economia global.
Ao longo de 2009 e 2010, o Bitcoin permaneceu como um experimento entre os entusiastas da tecnologia e das criptomoedas. As primeiras transações de Bitcoin ocorreram entre participantes da rede, e o primeiro uso comercial da moeda ocorreu em 22 de maio de 2010, quando um programador chamado Laszlo Hanyecz comprou duas pizzas por 10 mil Bitcoins. Esta transação histórica foi apelidada de “Bitcoin Pizza Day”.
Satoshi Nakamoto continuou a contribuir para o desenvolvimento do Bitcoin até o final de 2010, quando desapareceu gradualmente da comunidade. Até hoje, sua identidade permanece um mistério e não há evidências concretas de quem ou quantas pessoas estavam por trás do pseudônimo. Antes de sair, Satoshi Nakamoto entregou o controle do projeto a outros desenvolvedores e deixou claro que o Bitcoin deveria ser uma tecnologia descentralizada, de propriedade de todos e controlada por ninguém.
Desde então, o Bitcoin cresceu exponencialmente. Cresceu de um experimento tecnológico para um ativo multibilionário e é amplamente considerada a forma legítima de moeda digital e reserva de valor. Governos, empresas e indivíduos em todo o mundo adotaram o Bitcoin como alternativa às moedas fiat tradicionais.
Resumindo, a criação do Bitcoin por Satoshi Nakamoto foi mais do que apenas o nascimento de uma moeda digital; Este foi o início de um movimento global para repensar a forma como o dinheiro é controlado e distribuído. Embora a identidade de Satoshi Nakamoto permaneça desconhecida, o seu legado continuará a moldar o futuro do sistema financeiro e a desafiar as estruturas económicas tradicionais.
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 14:57:11The coffee tastes burnt. Dad stirs his black coffee with a plastic spoon. His hands shake a little. Seventy years of working hands.
"How are the girls?"
"Good. Emma lost her first tooth. Sophie's learning to ride her bike."
He smiles. First real smile I've seen from him in months.
"Remember when you learned? Took you all summer. Scraped knees every day. Kept getting back on."
A seagull lands on the window ledge. Fat from tourist scraps.
"Your mother says Sophie looks like you did at that age. Same stubborn streak."
"She gets that honest."
We watch people walk the beach. Families. Couples. Kids building sandcastles that won't last the tide.
"How's retirement treating you?"
"Can't complain. Get to spend time with the kids. Help with homework."
"Lucky man. Forty-three and done."
His coffee sits untouched now. Getting cold.
"Market's been crazy lately."
"Yeah?"
"Down thirty percent this year. Everything I put away for forty years. Just... gone."
The seagull flies away. Smarter than us.
"Your mother keeps watching the news. Every day it's worse. Says maybe we should sell. Cut our losses."
"Timing the market's tough."
"Tell me about it. Bought high. Always buy high."
An old couple walks past. Moving slow but still moving.
"Your uncle says it'll come back. Says to buy more while it's cheap. Easy for him to say."
"He's got different circumstances."
"That's what I told your mother. But you know how she listens to him."
Dad finally drinks his coffee. Makes a face. Cold and bitter.
"Your sister called yesterday."
"Yeah?"
"Needs money for the lawyer. Divorce is getting messy."
"Sorry to hear that."
"Can't say no to my kids. Even when they're forty-two."
His shoulders sag. Seventy years of carrying weight.
"How's the night shift?"
"Long. Double shifts most weeks."
"That's rough."
"Back's killing me. Feet hurt. Everything hurts."
The tide is going out. Leaving shells and debris on the sand.
"Mom's job situation?"
His face goes dark.
"They're shipping it overseas. AI's taking the rest. Forty years of experience. Means nothing now."
We sit in the quiet. Two men running out of safe ground.
"Dad?"
"Yeah?"
He looks at his hands. Working hands. Tired hands.
"Son, we can't retire."
The words hang between us like smoke. Everything we've been dancing around. Everything he's been trying not to say.
The market. The job. The sister. The uncle's bad advice. All of it leading here.
To this moment. This truth.
I want to fix it. Want to offer solutions. Want to give him some Bitcoin or a check.
But I don't.
The waitress brings the check. I reach for my wallet.
"I got it."
"Dad, let me—"
"I got it."
He counts out bills slowly. Leaves a decent tip.
Sometimes the best thing you can give someone is silence. Let them keep their dignity intact.
The ocean takes. The ocean gives back. But never what you expect.
Only what remains.

2025-06-15 14:46:35The new website is finally live! I put in a lot of hard work over the past months on it. I'm proud to say that it's out now and it looks pretty cool, at least to me!
Why rewrite it all?
The old kycnot.me site was built using Python with Flask about two years ago. Since then, I've gained a lot more experience with Golang and coding in general. Trying to update that old codebase, which had a lot of design flaws, would have been a bad idea. It would have been like building on an unstable foundation.
That's why I made the decision to rewrite the entire application. Initially, I chose to use SvelteKit with JavaScript. I did manage to create a stable site that looked similar to the new one, but it required Jav aScript to work. As I kept coding, I started feeling like I was repeating "the Python mistake". I was writing the app in a language I wasn't very familiar with (just like when I was learning Python at that mom ent), and I wasn't happy with the code. It felt like spaghetti code all the time.
So, I made a complete U-turn and started over, this time using Golang. While I'm not as proficient in Golang as I am in Python now, I find it to be a very enjoyable language to code with. Most aof my recent pr ojects have been written in Golang, and I'm getting the hang of it. I tried to make the best decisions I could and structure the code as well as possible. Of course, there's still room for improvement, which I'll address in future updates.
Now I have a more maintainable website that can scale much better. It uses a real database instead of a JSON file like the old site, and I can add many more features. Since I chose to go with Golang, I mad e the "tradeoff" of not using JavaScript at all, so all the rendering load falls on the server. But I believe it's a tradeoff that's worth it.
What's new
- UI/UX - I've designed a new logo and color palette for kycnot.me. I think it looks pretty cool and cypherpunk. I am not a graphic designer, but I think I did a decent work and I put a lot of thinking on it to make it pleasant!
- Point system - The new point system provides more detailed information about the listings, and can be expanded to cover additional features across all services. Anyone can request a new point!
- ToS Scrapper: I've implemented a powerful automated terms-of-service scrapper that collects all the ToS pages from the listings. It saves you from the hassle of reading the ToS by listing the lines that are suspiciously related to KYC/AML practices. This is still in development and it will improve for sure, but it works pretty fine right now!
- Search bar - The new search bar allows you to easily filter services. It performs a full-text search on the Title, Description, Category, and Tags of all the services. Looking for VPN services? Just search for "vpn"!
- Transparency - To be more transparent, all discussions about services now take place publicly on GitLab. I won't be answering any e-mails (an auto-reply will prompt to write to the corresponding Gitlab issue). This ensures that all service-related matters are publicly accessible and recorded. Additionally, there's a real-time audits page that displays database changes.
- Listing Requests - I have upgraded the request system. The new form allows you to directly request services or points without any extra steps. In the future, I plan to enable requests for specific changes to parts of the website.
- Lightweight and fast - The new site is lighter and faster than its predecessor!
- Tor and I2P - At last! kycnot.me is now officially on Tor and I2P!
How?
This rewrite has been a labor of love, in the end, I've been working on this for more than 3 months now. I don't have a team, so I work by myself on my free time, but I find great joy in helping people on their private journey with cryptocurrencies. Making it easier for individuals to use cryptocurrencies without KYC is a goal I am proud of!
If you appreciate my work, you can support me through the methods listed here. Alternatively, feel free to send me an email with a kind message!
Technical details
All the code is written in Golang, the website makes use of the chi router for the routing part. I also make use of BigCache for caching database requests. There is 0 JavaScript, so all the rendering load falls on the server, this means it needed to be efficient enough to not drawn with a few users since the old site was reporting about 2M requests per month on average (note that this are not unique users).
The database is running with mariadb, using gorm as the ORM. This is more than enough for this project. I started working with an
sqlite
database, but I ended up migrating to mariadb since it works better with JSON.The scraper is using chromedp combined with a series of keywords, regex and other logic. It runs every 24h and scraps all the services. You can find the scraper code here.
The frontend is written using Golang Templates for the HTML, and TailwindCSS plus DaisyUI for the CSS classes framework. I also use some plain CSS, but it's minimal.
The requests forms is the only part of the project that requires JavaScript to be enabled. It is needed for parsing some from fields that are a bit complex and for the "captcha", which is a simple Proof of Work that runs on your browser, destinated to avoid spam. For this, I use mCaptcha.

2025-06-17 15:44:41O Bitcoin tem se destacado como uma opção moderna para reserva de valor, frequentemente comparado a bens tradicionais como o ouro. Sua habilidade de resistir à inflação, junto com características como escassez, descentralização e segurança, o coloca como uma ferramenta promissora para preservar riqueza em tempos de incerteza econômica.
Uma reserva de valor é um ativo que mantém seu poder de compra ao longo do tempo, protegendo o patrimônio contra desvalorização. Historicamente, ativos como ouro e imóveis desempenharam esse papel, pois são relativamente escassos e têm demanda constante.
No entanto, moedas fiduciárias têm se mostrado menos eficientes como reserva de valor devido à inflação. Governos e bancos centrais frequentemente aumentam a oferta de dinheiro, o que pode diminuir o poder de compra das moedas. É nesse cenário que o Bitcoin se destaca como uma alternativa.
Bitcoin: escassez programada
A principal característica que torna o Bitcoin uma possível reserva de valor é sua oferta limitada. Apenas 21 milhões de bitcoins serão criados, um teto estabelecido em seu código. Essa escassez programada contrasta com as moedas fiduciárias, que podem ser emitidas sem limites por governos, resultando em inflação.
O processo de criação do Bitcoin também é controlado por eventos conhecidos como halvings, que cortam pela metade a recompensa por bloco minerado aproximadamente a cada quatro anos. Isso faz com que o Bitcoin se torne cada vez mais raro ao longo do tempo, aumentando seu potencial de valorização.
O Bitcoin oferece uma solução para o problema da inflação, pois sua oferta fixa evita que governos ou instituições centralizadas manipulem sua quantidade.
Descentralização e imutabilidade: por operar em uma rede descentralizada, o Bitcoin é imune a decisões políticas ou intervenções de bancos centrais. Nenhuma autoridade pode mudar o protocolo para "imprimir" mais bitcoins.
Transparência no suprimento: todas as transações e criações de novos bitcoins estão registradas no blockchain ou timechain, garantindo total transparência.
Proteção de poder de compra: com a oferta limitada e a crescente demanda, o Bitcoin tem mostrado tendência de valorização ao longo dos anos, funcionando como um hedge (proteção) contra a inflação em várias economias.
O Bitcoin é frequentemente chamado de "ouro digital" devido a suas semelhanças com o metal precioso como reserva de valor: Escassez: O ouro é limitado na natureza, enquanto o Bitcoin tem um suprimento máximo programado de 21 milhões de unidades.
Portabilidade: o Bitcoin é mais fácil de transferir e armazenar do que o ouro, sendo acessível digitalmente em qualquer lugar do mundo.
Divisibilidade: cada bitcoin pode ser dividido em até 100 milhões de unidades chamadas satoshis, permitindo transações de qualquer valor.
Segurança: enquanto o ouro exige armazenamento físico e está sujeito a roubo, o Bitcoin pode ser guardado em carteiras digitais seguras.
Essas qualidades fazem do Bitcoin uma opção mais flexível e acessível como forma de guardar valor em um mundo cada vez mais digital.
Apesar de sua promessa, o Bitcoin ainda enfrenta barreiras para ser aceito amplamente como reserva de valor:
Volatilidade: o valor do Bitcoin historicamente tem apresentado grandes variações, o que pode desestimular investidores que desejam segurança. Contudo, muitos acreditam que, com o aumento da aceitação, a volatilidade tende a diminuir.
Regulação: alguns governos têm implementado ações para restringir ou regular o uso do Bitcoin, o que pode impactar sua aceitação como reserva de valor.
Adaptação cultural: como um ativo novo e digital, o Bitcoin ainda precisa ganhar a confiança de pessoas que estão acostumadas a formas de valor físicas, como o ouro.
O Bitcoin tem se destacado como uma opção de guarda de valor particularmente útil em economias que enfrentam crises financeiras ou hiperinflação. Países como Venezuela, Argentina e Zimbábue, que passaram por uma queda acentuada de suas moedas, viram um crescimento na adoção do Bitcoin como maneira de proteger o poder de compra.
Além disso, sua acessibilidade mundial permite que pessoas em países sem fácil acesso a mercados financeiros tradicionais utilizem o Bitcoin como uma alternativa.
Resumindo, o Bitcoin possui características distintas que o fazem um candidato promissor como reserva de valor em um mundo cada vez mais digital e afetado pela inflação das moedas comuns. Sua escassez programada, resistência à manipulação e acessibilidade global oferecem uma solução moderna para conservar riqueza.
Embora dificuldades como volatilidade e regulação ainda precisem ser superadas, o Bitcoin já se mostrou uma ferramenta eficaz para proteger ativos, especialmente em contextos de instabilidade econômica. Com o tempo e um aumento na aceitação, o Bitcoin pode se consolidar como um dos principais ativos de reserva de valor no século XXI.
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 14:13:58Bitcoin 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 14:56:53Bitcoin é uma moeda digital descentralizada criada em 2009 por um indivíduo ou grupo sob o pseudônimo de Satoshi Nakamoto. Ao contrário das moedas tradicionais emitidas pelo governo, como o dólar americano ou o euro, o Bitcoin não é controlado por nenhuma autoridade central, como um banco central ou uma instituição financeira. Esta característica inovadora tornou-o foco do debate económico, tecnológico e até mesmo social nos últimos anos.
O Bitcoin funciona com uma tecnologia chamada blockchain (que atualmente a comunidade Bitcoin prefere chamá-la de timechain), é essencialmente um livro digital distribuído. O blockchain ou timechain registra todas as transações feitas na rede Bitcoin de forma aberta e transparente. Cada bloco contém um conjunto de transações que são adicionadas de forma imutável à cadeia, assim que são verificadas pelos mineradores (mineradores são basicamente participantes da rede que usam seu poder computacional para verificar essas mesmas transações). Isto garante a segurança e evita fraudes, uma vez que nenhuma pessoa ou entidade pode alterar retroativamente os registos.
Uma das melhores características do Bitcoin é a sua oferta limitada. Apenas podem ser criados 21 milhões de Bitcoins, o que por este mesmo motivo o Bitcoin apresenta um carácter deflacionário, ao contrário da moeda fiduciária, que os bancos centrais podem imprimir em quantidades ilimitadas. Este limite fixo, combinado com o crescente interesse global pela tecnologia em geral e pela privacidade de modo individual impulsiona a valorização do Bitcoin ao passar do tempo.
Outra característica do Bitcoin é que ele permite transações diretas entre pessoas, eliminando intermediários. Isto é particularmente útil em cenários como transferências internacionais, onde o Bitcoin pode ser utilizado para enviar dinheiro rapidamente e com taxas reduzidas, sem ter que passar por um banco ou serviços financeiros tradicionais no geral. Além disso, é visto como uma forma de liberdade financeira em países com moedas locais instáveis (quase sempre efeito dos bancos centrais imprimem dinheiro de forma completamente descontolada) ou controlos rígidos estatais sobre o capital.
Porém, o Bitcoin não está imune a críticas que tendem sempre a ser críticas vazias que mascaram os interesses pessoais de quem as faz, seja porque trabalham em bancos ou corretoras tradicionais e têm medo de perder o “poder” ou até mesmo o emprego ou então porque têm más intenções e querem vender as suas criptomoedas que no fundo são todas inúteis (as famosas shitcoins). As oscilações de preço do Bitcoin também podem significar riscos enormes para usuários que são no fundo iniciantes, compram por determinado preço e acabam por vender quando o valor caiu pela metade (perdendo pelo menos metade do seu dinheiro). Por outro lado, muitos especialistas consideram o Bitcoin um marco tecnológico e social que desafia os modelos económicos existentes.
Resumindo, o Bitcoin é muito mais do que uma “crypto“ ou “criptomoeda“. Representa uma revolução ou revisão na forma como a maioria dos seres humanos pensam sobre o dinheiro, proporcionando uma alternativa descentralizada, transparente e resistente ao roubo ou atê mesmo à censura. Embora ainda enfrente alguns desafios para ser amplamente aceite por alguns cépticos e por alguns governos preocupados com a perda de controlo das “suas” próprias populações (como mencionado anteriormente), o seu impacto tem sido inegável, abrindo caminho para uma nova era na economia global e abrindo a mente de muitas pessoas para a reflexão.

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 15:52:20As regulações têm um papel fundamental na evolução do mercado financeiro global, criando as bases para a estabilidade, segurança e confiança nas transações econômicas. Porém, em um mundo cada vez mais globalizado e digital, os desafios regulatórios se tornaram mais complicados, especialmente com o surgimento de inovações financeiras disruptivas, como o Bitcoin e as finanças descentralizadas. A interação entre a regulação e o mercado financeiro tem profundas consequências, tanto boas quanto ruins, moldando o futuro da economia global.
A importância das regulações no mercado financeiro:
Estabilidade econômica: leis e regulamentações financeiras ajudam a evitar práticas arriscadas, como empréstimos irresponsáveis e especulação excessiva.
Proteção ao consumidor: regulamentos garantem que consumidores e investidores tenham acesso a informações claras e precisas, evitando fraudes e abusos.
Combate à lavagem de dinheiro e financiamento ao terrorismo: políticas de “conheça seu cliente” (KYC) e combate à lavagem de dinheiro (AML) asseguram que recursos ilegais não ingressem no sistema financeiro.
Desafios regulatórios em um mercado globalizado:
Interconectividade dos mercados: o mercado financeiro global é interconectado, e crises em um país podem rapidamente se espalhar para outros. Isso requer uma coordenação internacional mais eficiente entre os reguladores.
Inovações tecnológicas: o surgimento de tecnologias disruptivas, como o blockchain ou timechain, desafiou os modelos regulatórios clássicos. Muitos governos ainda estão tentando equilibrar a promoção da inovação com a redução de riscos.
Compliance e custos: empresas financeiras enfrentam custos crescentes para atender regulamentações cada vez mais severas, o que pode afetar sua lucratividade e criar barreiras para novos entrantes.
Impacto das regulações no mercado financeiro global:
Impactos positivos: confiança do Investidor: Regras claras e aplicação eficaz aumentam a confiança dos investidores, promovendo o crescimento do mercado financeiro.
Resiliência econômica: regulamentações bem elaboradas tornam o sistema financeiro mais forte contra choques econômicos.
Atração de capital estrangeiro: jurisdições com boa governança regulatória atraem investimentos de países e empresas em busca de segurança.
Impactos negativos: excesso de burocracia: regras muito complicadas podem tornar difícil a inovação e o crescimento econômico, especialmente para pequenas empresas.
Fuga de capital: empresas podem mover suas operações para países com leis mais fáceis, prejudicando a economia de lugares com regras mais rígidas.
Ineficácia em contextos lobais: regras nacionais nem sempre funcionam bem em mercados globais. A falta de cooperação entre países pode criar oportunidades para pessoas mal-intencionadas.
O papel das instituições internacionais:
Padrões Internacionais: essas organizações trabalham para criar padrões globais, como os de capital mínimo para bancos (Acordos de Basileia).
Resolução de crises: instituições internacionais também funcionam como mediadoras e fornecedoras de ajuda financeira em crises globais, como visto durante a pandemia de 2020-2021.
Regulação e inovação (equilíbrio necessário):
Incentivo à Inovação: reguladores devem manter as tecnologias emergentes em crescimento, permitindo que soluções como o blockchain ou timechain se desenvolvam.
Riscos associados à falta de regulação: sem regras apropriadas, mercados inovadores podem atrair ações fraudulentas, prejudicando a confiança pública.
Resumindo, as regulamentações são essenciais para manter a integridade e a estabilidade do mercado financeiro global. Elas asseguram a proteção dos participantes, previnem crises e fomentam um ambiente confiável. Contudo, o mundo globalizado e a rápida mudança tecnológica desafiam os reguladores a se adaptarem continuamente.
O equilíbrio entre segurança e inovação é vital para o futuro do mercado financeiro. Regras eficazes devem ser adaptáveis o bastante para acompanhar as mudanças e suficientemente fortes para proteger os participantes. Assim, o mercado financeiro global pode continuar a se desenvolver, promovendo prosperidade econômica de forma sustentável e justa.

2025-06-17 15:16:09A 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.

2025-06-17 15:49:45O Bitcoin trouxe uma nova maneira de entender a economia monetária, rompendo com os modelos inflacionários das moedas tradicionais e apresentando uma estrutura deflacionária especial. Com uma oferta restrita e regras matemáticas claras, o Bitcoin proporciona previsibilidade, segurança e resistência a manipulações, características que atraem investidores e fãs ao redor do mundo.
Um dos aspectos mais importantes do Bitcoin é sua oferta limitada a 21 milhões de unidades, definida no código original por Satoshi Nakamoto. Essa característica separa o Bitcoin das moedas tradicionais, cuja oferta é ilimitada e muitas vezes aumentada por bancos centrais para atender a necessidades econômicas ou políticas.
A oferta limitada dá ao Bitcoin uma qualidade semelhante ao ouro, sendo frequentemente chamado de "ouro digital". Assim como o ouro, o Bitcoin é escasso e requer esforço para ser adquirido (por meio de mineração). A escassez programada cria uma dinâmica de oferta e demanda que tende a aumentar o valor do ativo à medida que a demanda cresce e a oferta se mantém constante.
A emissão de novos bitcoins acontece através da mineração, e as recompensas são reduzidas pela metade em eventos chamados halvings, que ocorrem aproximadamente a cada quatro anos. Essa diminuição gradual na emissão de novos bitcoins assegura que a quantidade total será alcançada por volta de 2140, tornando o Bitcoin previsível a longo prazo.
O modelo deflacionário do Bitcoin é definido pela diminuição na criação de novas unidades e pelo aumento potencial de seu valor com o tempo. Isso contrasta diretamente com o modelo inflacionário das moedas tradicionais, nas quais a oferta é constantemente aumentada, reduzindo seu poder de compra.
A deflação no Bitcoin acontece porque a oferta de novos bitcoins diminui enquanto a demanda global tende a aumentar. Em vez de perder poder de compra, como ocorre com moedas tradicionais, o Bitcoin tem potencial de valorização à medida que mais pessoas buscam guardá-lo como valor.
Economias que dependem de sistemas deflacionários enfrentam desafios, como a tendência dos consumidores de adiar gastos na expectativa de preços mais baixos. Contudo, no caso do Bitcoin, ele é visto principalmente como uma reserva de valor, diminuindo esse efeito negativo. Por outro lado, o modelo deflacionário estimula a poupança, protegendo a riqueza das pessoas contra desvalorizações arbitrárias.
O modelo inflacionário das moedas fiduciárias se baseia na ampliação da oferta monetária para impulsionar o crescimento econômico, o que, na prática, reduz o poder de compra das moedas ao longo do tempo.
Governos e bancos centrais frequentemente imprimem dinheiro para pagar dívidas ou estimular a economia, o que pode resultar em inflação descontrolada.
Esse aumento na quantidade de dinheiro diminui o valor do dinheiro já existente, prejudicando poupadores e pessoas com menos acesso a ativos que protejam contra a inflação.
Como o Bitcoin é descentralizado e funciona em uma rede pública, nenhuma entidade central pode mudar suas regras ou aumentar sua oferta.
Isso o torna um ativo confiável para quem quer proteger sua riqueza em economias instáveis ou inflacionárias.
De maneira resumida a economia do Bitcoin é principalmente movida pela interação entre oferta e demanda.
O aumento da aceitação global, tanto por investidores institucionais quanto por indivíduos, gerou maior demanda pelo Bitcoin.
Sua utilidade como reserva de valor e defesa contra inflação atrai pessoas de economias frágeis e investidores em busca de diversificação.
Cada halving reduz a criação de novos bitcoins, diminuindo a oferta no mercado. Historicamente, esses eventos têm sido seguidos por aumentos significativos no preço do Bitcoin, pois a oferta menor atende a uma demanda crescente.
Com a oferta limitada e um cronograma previsível de emissão, o Bitcoin funciona de maneira clara, evitando surpresas econômicas comuns em sistemas fiduciários manipulados por bancos centrais.
Com o tempo, o Bitcoin pode ter um papel cada vez mais importante na economia global. Seu modelo deflacionário é especialmente atraente em um contexto de crescente desconfiança em relação às moedas fiduciárias e aos sistemas financeiros tradicionais.
O Bitcoin está se estabelecendo como uma reserva de valor, parecido com o ouro, mas com vantagens em portabilidade e divisibilidade.
Em períodos de crise econômica, ele é visto como uma alternativa segura para proteger riquezas.
À medida que a recompensa pela mineração diminui, espera-se que as taxas de transação sustentem a rede, aumentando sua segurança sem afetar a economia dos usuários.
Resumindo, a economia do Bitcoin é uma inovação que desafia os conceitos estabelecidos pelas moedas fiduciárias. Com sua oferta limitada, modelo deflacionário e resistência à manipulação, ele oferece uma alternativa forte para proteger a riqueza contra os efeitos da inflação.
Apesar de enfrentar desafios, como volatilidade e aceitação global, o Bitcoin continua a se fortalecer como uma reserva de valor confiável e uma forma de dinheiro digital. Seu modelo econômico, baseado na escassez e na transparência, pode ter um impacto duradouro na forma como pessoas e instituições lidam com o armazenamento e a preservação de valor no século XXI.

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

2025-06-17 14:02:01While most Bitcoin companies chase quick wins with flashy marketing and complex trading features, Coinfinity is taking a different path. The Austria-based company has built their entire business model around something most brokers treat as an afterthought: education.
Founded on the principle that Bitcoin adoption requires understanding, not just access, Coinfinity offers something great in the Bitcoin space: a broker that actually wants you to take your bitcoin off their platform.
Their Bitcoin Blinks educational series provides a self-custody-first approach, and Austrian economics foundation make them stand out in a crowded field of crypto casinos.
Coinfinity’s HQ in Graz, Austria
At the heart of this educational mission is Fab, Coinfinity’s Head of Bitcoin Education, whose journey to Bitcoin mirrors that of many who’ve found their way to Austrian economics through pure instinct.
“I always had the feeling that something in the world just doesn’t add up,” he told Bitcoin News when he sat down with us. “Something’s wrong, I don’t know what, but I felt like the foundation of our society isn’t quite fair, I just never knew what it was.”
Sound familiar?
That hunch eventually led him down a rabbit hole of geopolitics, monetary systems, and finally to Andreas Antonopoulos videos on YouTube.
“I basically disappeared from life for about a week, just watching those videos,” Fab recalled. But it wasn’t until he read The Bitcoin Standard that everything clicked.
“I remember it like it was yesterday, I closed the book and thought ‘Holy s***, now I get it.’ That was the moment. From then on, I was Bitcoin-only.”
Many of the best Bitcoin books are in English and translating them is important
Now as Head of Bitcoin Education at Coinfinity and co-founder of Aprycot Media (a German publishing house focused exclusively on Bitcoin), Fab spends his days helping others find that same spark.
And unlike most “crypto” companies, Coinfinity’s strategy isn’t driven by marketing gimmicks or token launches, it’s driven by teaching.
“Our goal is to create educational content that’s so easy to understand that people love sharing it,” Fab explained. “When they share it, they connect with us. Once they start understanding Bitcoin, they choose us to buy it.”
Most companies buy Google ads. Coinfinity builds minds. With their Bitcoin Blinks, 42 short, clear lessons covering everything from subjective value to seed phrases, they’re offering what most brokers won’t: context. Meaning. Philosophy.
“It became quite popular, and we think it’s way more effective for our brand than just buying ads,” Fab said.
And they don’t stop there. When it comes to custody, Coinfinity takes a radically different approach than most Bitcoin brokers.
“When you buy bitcoin from us, you always take custody, either in our in-app wallet where you control the seed, or your own hardware wallet,” Fab emphasized. “Even our lightning feature works the same way you always buy into your own wallet.”
That’s not just a slogan. It’s a core value of the company that runs so deep they’re willing to sacrifice user experience for it. “We never custody your bitcoin,” Fab said. “It’s one of the core values that you custody them yourself.”
Even as fees rise and UTXO management gets harder, Coinfinity stays committed to self-custody. They are open to optional custodial tools in the future, but always paired with education, and always encouraging users to take their bitcoin off-platform when the time is right.
“If we ever offer custodial services, it would only be to help users stack small amounts until they reach a meaningful UTXO size,” Fab explained.
The plan would involve accumulating smaller purchases monthly or weekly until users hit a threshold, maybe a million sats, then withdrawing to self-custody. “We don’t want to play games with your bitcoin. We don’t want to lend it out or earn interest on it.”
Coinfinity emphasizes on self-custody and education, even in its app
The challenge is real though. When new users first encounter Bitcoin, the technical barriers can be overwhelming. “Often causes problems with people just getting into Bitcoin who don’t understand what self custody is” Fab notes.
That’s why they built their in-app wallet, to smooth the onboarding while maintaining their self-custody values. “The in-app wallet was our first step toward optimizing user experience without compromising our core value of bringing bitcoin into self-custody,” he said.
“One of our taglines is ‘bringing Bitcoin to the people’ and we literally mean that. We want to bring bitcoin to them, not keep it from them.”
Another promising thing the company is doing in their operations is using AI to create more content, faster. Podcast scripts, educational summaries, internal tools, Fab’s even feeding Austrian economics PDFs into models to keep the tone on-brand and Bitcoin-only.
“We’re using these tools in our business development and marketing teams to generate more output with the same number of people,” he said. But the future looks even more exciting.
“Maybe one day we’ll have a tutor in the app where you can do a video call and ask ‘What is a Bitcoin address?’ and it will talk back to you naturally, going deeper as you ask more questions,” Fab explained. “That’s absolutely possible.”
The technology isn’t quite there yet for mainstream deployment in their app, but Fab is optimistic. “I’m sure that in the future, this won’t just be used for improving our internal workflow, but for enhancing the content itself,” he said.
It’s not a pipe dream. The tech is already close. The only thing missing is more Bitcoin-native data and companies like Coinfinity are quietly building that layer.
One of the favorite parts of these interviews is asking the builders in the space what they would ask Satoshi if given one question. When I asked Fab what he’d ask Bitcoin’s creator, he didn’t hesitate:
“Did you purposely build Bitcoin based on Austrian economics, or did it just happen by accident?
“All this monetization theory, Bitcoin being a store of value first, is this something you actually thought was possible and had in mind? Or was it just a lucky shot that accidentally gave us the best monetary properties?”
Because if Satoshi had built Bitcoin with a 2% inflation rate, like some other projects, it might’ve worked. But it wouldn’t have lasted.
“He could have made it with 2% tail emission, it still would have been decentralized. But then today, someone might introduce a coin with a fixed supply that could kill Bitcoin,” Fab noted.
Fab suspects the fixed supply wasn’t an accident. And thank God for that.
What’s remarkable about Coinfinity isn’t just their Austrian approach or their self-custody obsession, it’s how they’re proving that education-first Bitcoin companies can compete with the flashy crypto casinos dominating the space.
Coinfinity doesn’t serve U.S. customers. They’re focused on Europe, operating within EU regulations. But what they’re building, honest Bitcoin education, smart tools, and a relentless push for financial sovereignty, matters everywhere.

2025-06-06 20:48:33Vibe coding is taking the nostr developer community by storm. While it's all very exciting and interesting, I think it's important to pump the brakes a little - not in order to stop the vehicle, but to try to keep us from flying off the road as we approach this curve.
In this note Pablo is subtweeting something I said to him recently (although I'm sure he's heard it from other quarters as well):
nostr:nevent1qvzqqqqqqypzp75cf0tahv5z7plpdeaws7ex52nmnwgtwfr2g3m37r844evqrr6jqy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qghwaehxw309aex2mrp0yh8qunfd4skctnwv46z7qg6waehxw309ac8junpd45kgtnxd9shg6npvchxxmmd9uqzq0z48d4ttzzkupswnkyt5a2xfkhxl3hyavnxjujwn5k2k529aearwtecp4
There is a naive, curmudgeonly case for simply "not doing AI". I think the intuition is a good one, but the subject is obviously more complicated - not doing it, either on an individual or a collective level, is just not an option. I recently read Tools for Conviviality by Ivan Illich, which I think can help us here. For Illich, the best kind of tool is one which serves "politically interrelated individuals rather than managers".
This is obviously a core value for bitcoiners. And I think the talks given at the Oslo Freedom Forum this year present a compelling case for adoption of LLMs for the purposes of 1. using them for good, and 2. developing them further so that they don't get captured by corporations and governments. Illich calls both the telephone and print "almost ideally convivial". I would add the internet, cryptography, and LLMs to this list, because each one allows individuals to work cooperatively within communities to embody their values in their work.
But this is only half the story. Illich also points out how "the manipulative nature of institutions... have put these ideally convivial tools at the service of more [managerial dominance]."
Preventing the subversion and capture of our tools is not just a matter of who uses what, and for which ends. It also requires an awareness of the environment that the use of the tool (whether for virtuous or vicious ends) creates, which in turn forms the abilities, values, and desires of those who inhabit the environment.
The natural tendency of LLMs is to foster ignorance, dependence, and detachment from reality. This is not the fault of the tool itself, but that of humans' tendency to trade liberty for convenience. Nevertheless, the inherent values of a given tool naturally gives rise to an environment through use: the tool changes the world that the tool user lives in. This in turn indoctrinates the user into the internal logic of the tool, shaping their thinking, blinding them to the tool's influence, and neutering their ability to work in ways not endorsed by the structure of the tool-defined environment.
The result of this is that people are formed by their tools, becoming their slaves. We often talk about LLM misalignment, but the same is true of humans. Unreflective use of a tool creates people who are misaligned with their own interests. This is what I mean when I say that AI use is anti-human. I mean it in the same way that all unreflective tool use is anti-human. See Wendell Berry for an evaluation of industrial agriculture along the same lines.
What I'm not claiming is that a minority of high agency individuals can't use the technology for virtuous ends. In fact, I think that is an essential part of the solution. Tool use can be good. But tools that bring their users into dependence on complex industry and catechize their users into a particular system should be approached with extra caution. The plow was a convivial tool, and so were early tractors. Self-driving John Deere monstrosities are a straightforward extension of the earlier form of the technology, but are self-evidently an instrument of debt slavery, chemical dependency, industrial centralization, and degradation of the land. This over-extension of a given tool can occur regardless of the intentions of the user. As Illich says:
There is a form of malfunction in which growth does not yet tend toward the destruction of life, yet renders a tool antagonistic to its specific aims. Tools, in other words, have an optimal, a tolerable, and a negative range.
The initial form of a tool is almost always beneficial, because tools are made by humans for human ends. But as the scale of the tool grows, its logic gets more widely and forcibly applied. The solution to the anti-human tendencies of any technology is an understanding of scale. To prevent the overrun of the internal logic of a given tool and its creation of an environment hostile to human flourishing, we need to impose limits on scale.
Tools that require time periods or spaces or energies much beyond the order of corresponding natural scales are dysfunctional.
My problem with LLMs is:
- Not their imitation of human idioms, but their subversion of them and the resulting adoption of robotic idioms by humans
- Not the access they grant to information, but their ability to obscure accurate or relevant information
- Not their elimination of menial work, but its increase (Bullshit Jobs)
- Not their ability to take away jobs, but their ability to take away the meaning found in good work
- Not their ability to confer power to the user, but their ability to confer power to their owner which can be used to exploit the user
- Not their ability to solve problems mechanistically, but the extension of their mechanistic value system to human life
- Not their explicit promise of productivity, but the environment they implicitly create in which productivity depends on their use
- Not the conversations they are able to participate in, but the relationships they displace
All of these dysfunctions come from the over-application of the technology in evaluating and executing the fundamentally human task of living. AI work is the same kind of thing as an AI girlfriend, because work is not only for the creation of value (although that's an essential part of it), but also for the exercise of human agency in the world. In other words, tools must be tools, not masters. This is a problem of scale - when tool use is extended beyond its appropriate domain, it becomes what Illich calls a "radical monopoly" (the domination of a single paradigm over all of human life).
So the important question when dealing with any emergent technology becomes: how can we set limits such that the use of the technology is naturally confined to its appropriate scale?
Here are some considerations:
- Teach people how to use the technology well (e.g. cite sources when doing research, use context files instead of fighting the prompt, know when to ask questions rather than generate code)
- Create and use open source and self-hosted models and tools (MCP, stacks, tenex). Refuse to pay for closed or third-party hosted models and tools.
- Recognize the dependencies of the tool itself, for example GPU availability, and diversify the industrial sources to reduce fragility and dependence.
- Create models with built-in limits. The big companies have attempted this (resulting in Japanese Vikings), but the best-case effect is a top-down imposition of corporate values onto individuals. But the idea isn't inherently bad - a coding model that refuses to generate code in response to vague prompts, or which asks clarifying questions is an example. Or a home assistant that recognized childrens' voices and refuses to interact.
- Divert the productivity gains to human enrichment. Without mundane work to do, novice lawyers, coders, and accountants don't have an opportunity to hone their skills. But their learning could be subsidized by the bots in order to bring them up to a level that continues to be useful.
- Don't become a slave to the bots. Know when not to use it. Talk to real people. Write real code, poetry, novels, scripts. Do your own research. Learn by experience. Make your own stuff. Take a break from reviewing code to write some. Be independent, impossible to control. Don't underestimate the value to your soul of good work.
- Resist both monopoly and "radical monopoly". Both naturally collapse over time, but by cultivating an appreciation of the goodness of hand-crafted goods, non-synthetic entertainment, embodied relationship, and a balance between mobility and place, we can relegate new, threatening technologies to their correct role in society.
I think in all of this is implicit the idea of technological determinism, that productivity is power, and if you don't adapt you die. I reject this as an artifact of darwinism and materialism. The world is far more complex and full of grace than we think.
The idea that productivity creates wealth is, as we all know, bunk. GDP continues to go up, but ungrounded metrics don't reflect anything about the reality of human flourishing. We have to return to a qualitative understanding of life as whole, and contextualize quantitative tools and metrics within that framework.
Finally, don't believe the hype. Even if AI delivers everything it promises, conservatism in changing our ways of life will decelerate the rate of change society is subjected to and allow time for reflection and proper use of the tool. Curmudgeons are as valuable as technologists. There will be no jobspocalypse if there is sufficient political will to value human good over mere productivity. It's ok to pump the breaks.

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.
- Learn more about the current and upcoming features of Bitcoin Safe wallet here.
What's new in v1.3
- Redesign of Chart, Quick Receive, Icons, and Mempool Preview (by @design-rrr).
- Interactive chart. Clicking on it now jumps to transaction, and selected transactions are now highlighted.
- Speed up transactions with Child Pays For Parent (CPFP).
- BDK 1.2 (upgraded from 0.32).
- Testnet4 support.

2025-06-05 08:51:39Global Metrics
Here are the top stats from the last period:
- Total Bitcoin-accepting merchants: 15,306 → 16,284
- Recently verified (1y): 7,540 → 7,803 (the rest of our dataset is slowly rotting; help us before it's too late!)
- Avg. days since last verification: 398 → 405 (more mappers, please)
- Merchants boosted: 22 (for a total of 4,325 days, someone is feeling generous)
- Comments posted: 34
Find current stats over at the 👉 BTC Map Dashboard.
Merchant Adoption
Steak n’ Shake
The US 🇺🇸 is a massive country, yet its BTC Map footprint has been lagging relative to other countries ... that is until now!
In what came as a nice surprise to our Shadowy Supertaggers 🫠, the Steak ’n Shake chain began accepting Bitcoin payments across hundreds of its locations nationwide (with some international locations too).
According to CoinDesk, the rollout has been smooth, with users reporting seamless transactions powered by Speed.
This marks a significant step towards broader Bitcoin adoption in the US. Now to drop the capital gains tax on cheesburgers!
SPAR Switzerland
In other chain/franchise adoption news, the first SPAR supermarket in Switzerland 🇨🇭 to begin accepting Bitcoin was this one in Zug. It was quickly followed by this one in Rossrüti and this one in Kreuzlingen, in what is believed to be part of a wider roll-out plan within the country powered by DFX's Open CryptoPay.
That said, we believe the OG SPAR crown goes to SPAR City in Arnhem Bitcoin City!
New Features
Merchant Comments in the Web App
Web App users are now on par with Android users in that they can both see and make comments on merchants.
This is powered by our tweaked API that enables anyone to make a comment as long as they pass the satswall fee of 500 sats. This helps keep spam manageable and ensure quality comments.
And just in case you were wondering what the number count was on the merchant pins - yep, they're comments!
Here is an 👉 Example merchant page with comments.
Merchant Page Design Tweaks
To support the now trio of actions (Verify, Boost & Comment) on the merchant page, we've re-jigged the design a little to make things a little clearer.
What do you think?
Technical
Codebase Refactoring
Thanks to Hannes’s contributions, we’ve made progress in cleaning-up the Web App's codebase and completing long overdue maintenance. Whilst often thankless tasks, these caretaking activities help immensely with long-term maintainability enabling us to confidently build new features.
Auth System Upgrades
The old auth system was held together with duct tape and prayers, and we’re working on a more robust authentication system to support future public API access. Updates include:
- Password hashing
- Bearer token support
- Improved security practices
More enhancements are in progress and we'll update you in the next blog post.
Better API Documentation
Instead of relying on tribal knowledge, we're finally getting around to writing actual docs (with the help/hindrance of LLMs). The "move fast, break everything" era is over; now we move slightly slower and break slightly less. Progress!
Database Improvements
We use SQLite, which works well but it requires careful handling in async Rust environments. So now we're untangling this mess to avoid accidental blocking queries (and the ensuing dumpster fires).
Backup System Enhancements
BTC Map data comes in three layers of fragility:
- Merchants (backed up by OS - the big boys handle this)
- Non-OSM stuff (areas, users, etc. - currently stored on a napkin)
- External systems (Lightning node, submission tickets - pray to Satoshi)
We're now forcing two core members to backup everything, because redundancy is good.

2025-06-17 15:42:15A rede Bitcoin foi feita para ser segura, descentralizada e resistente à censura. Contudo, à medida que seu uso cresce, surge um desafio importante: a escalabilidade. Esse termo se refere à habilidade da rede de gerenciar um número crescente de transações sem afetar o desempenho ou a segurança. Esse desafio provocou o dilema de velocidade, que envolve equilibrar a rapidez nas transações com a preservação da descentralização e da segurança que o blockchain ou timechain proporciona.
Escalabilidade é a habilidade de um sistema aumentar seu desempenho para atender a demandas maiores. No caso do Bitcoin, isso implica processar um maior número de transações por segundo (TPS) sem comprometer os princípios básicos da rede.
Atualmente, a rede Bitcoin processa cerca de 7 transações por segundo, um número visto como baixo em comparação com sistemas tradicionais, como redes de cartões de crédito, que podem processar milhares de transações por segundo. Esse limite decorre diretamente do tamanho fixo dos blocos (1 MB) e do tempo médio de 10 minutos para a criação de um novo bloco no blockchain ou timechain.
O dilema de velocidade surge da necessidade de equilibrar três elementos essenciais: descentralização, segurança e velocidade.
O trilema do blockchain ou timechain:
Descentralização: a rede Bitcoin é composta por milhares de nós independentes, que verificam e validam transações. Aumentar os blocos ou torná-los mais rápidos poderia elevar os requisitos computacionais, dificultando a participação de nós menores e afetando a descentralização.
Segurança: a segurança vem do processo de mineração e da validação dos blocos. Aumentar a velocidade das transações poderia comprometer a segurança, pois diminuiria o tempo necessário para certificar cada bloco, tornando a rede mais propensa a ataques.
Velocidade: a necessidade de confirmar transações rapidamente é crucial para que o Bitcoin seja utilizado como meio de pagamento no cotidiano. Porém, priorizar a velocidade pode afetar tanto a segurança quanto a descentralização.
Esse dilema exige soluções equilibradas para expandir a rede sem sacrificar suas características essenciais.
Soluções para o problema de escalabilidade
Várias soluções têm sido sugeridas para solucionar os desafios de escalabilidade e velocidade na rede Bitcoin.
Otimização on-chain
Segregated witness (SegWit): implementado em 2017, o SegWit separa os dados de assinatura das transações, permitindo uma utilização mais eficiente do espaço nos blocos e aumentando a capacidade sem modificar o tamanho do bloco.
Aumento do tamanho do bloco: algumas propostas sugeriram aumentar o tamanho dos blocos para permitir mais transações por bloco. Contudo, isso poderia tornar o sistema mais centralizado, pois exigiria maior poder computacional.
Soluções off-chain
Lightning Network: uma solução de segunda camada que permite transações rápidas e de baixo custo fora da blockchain ou timechain principal. Essas transações são liquidadas depois na rede principal, mantendo a segurança e a descentralização.
Canais de Pagamento: ermitem transações diretas entre dois usuários sem a necessidade de registrar cada ação na rede, diminuindo a congestão.
Sidechains (cadeias paralelas): propostas que criam redes paralelas ligadas ao blockchain ou timechain principal, permitindo mais flexibilidade e capacidade de processamento.
Embora essas soluções tragam melhorias significativas, elas também apresentam problemas. A Lightning Network, por exemplo, depende de canais de pagamento que precisam de liquidez inicial, limitando sua adoção geral. O aumento do tamanho dos blocos pode tornar o sistema mais suscetível à centralização, impactando a segurança da rede.
Além disso, soluções de segunda camada podem exigir confiança extra entre os participantes, o que pode enfraquecer os princípios de descentralização e resistência à censura defendidos pelo Bitcoin.
Outro ponto importante é a necessidade de adoção em larga escala. Mesmo com avanços tecnológicos, as soluções só serão eficazes se forem amplamente usadas e aceitas pelos usuários e desenvolvedores.
Resumindo, a escalabilidade e o dilema de velocidade representam um dos maiores desafios técnicos para a rede Bitcoin. Embora a segurança e a descentralização sejam essenciais para manter os princípios originais do sistema, a necessidade de transações rápidas e eficientes torna a escalabilidade um tema urgente.
Soluções como o SegWit e a Lightning Network têm mostrado avanços promissores, mas ainda enfrentam barreiras técnicas e de adoção. O equilíbrio entre velocidade, segurança e descentralização continua sendo um objetivo central para o futuro do Bitcoin.
Assim, a busca por inovação e melhoria constante é essencial para que o Bitcoin mantenha sua relevância como uma rede confiável e eficiente, capaz de sustentar o crescimento e a adoção global sem comprometer seus valores fundamentais.
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!

2025-01-01 06:15:09Nostrでお世話になっている方も、お世話になってない方も、こんにちは!
タコ頭大吉です!
NIP-23を使った初めての投稿です。
今回は、私がここ数ヶ月中にデザインをした三種類のビタキセケースの紹介記事になります!!
ビタキセを買ったもののあまり自分の好みに合う外観や仕様のケースがなく、いくつかプロトタイプを作りそれなりに時間をかけて考えたケース達です。
これら3シリーズに関しては、FDMタイプの3Dプリンタの精度、耐久性、出力後の作業性を考慮して一つのパーツで完結することに拘って設計をしました。
一定以上の充填率でプリントをすればそれなりに丈夫なはずです。
また、基本的に放熱性と保護性を両立できるように設計をしたつもります。
それぞれのモデルについて簡単に紹介をさせていただきますので、よろしければ各リポジトリに付属のREADMEを読んでいただいて自作、フィードバックをいただけましたら幸いです。
それでは、簡単に各モデルの紹介をさせていたきます。
AirLiftFrame
最初に作ったモデルです! 少し大きいのが難点ですが、分厚めのフレームをベースとし基盤周辺をあえて囲わない設計により、保護性と放熱を阻害しない事の両立を狙っています。
TwinAirLiftFrame
ビタキセを買い増ししたことにより、複数台をカッコよく運用したいという需要が自分の中に出てきたので、AirLiftFrameを2つくっつけたら良いのではと言うごくごく単純な発想でつくり始めたケースです。 しかし、ただ横並びにしただけでは廃熱が干渉するだけではなく、DCジャックやUSBポートへのアクセスが阻害されるという問題にすぐに気がつきました。 そこで、WebUI上でディスプレイの表示を上下反転出来ることに注目し、2台を上下逆向きに取り付ける事でそれらの問題を解決しました!
VoronoiShell
AirLiftFrameシリーズのサイズを小型化する事から始めたプロジョクトです。 縦横の寸法の削減だけではなく、厚みを薄くつくリたいという希望がありました。 所が単純に薄くすると、持った時に発熱する背面パーツに手が触れてしまったり、落下などでぶつかった際に背面パーツが破損する懸念がありました。 そこで、(当初は付けたくはなかった)背面保護用のグリルをデザインする必要が出てきました。 初めは多角形でしたがあまりにもダサく、調べている内にVoronoi柄という有機的なパターンに行き付き即採用しました。 結果、ビタキセを取り付けると柄が見えなくなるのが勿体無いぐらい個性的でスタイリッシュなデザインに仕上がりました。
いずれカスタム方法やインサートナットや増設ファンの選定方法等を紹介したいのですが、今回はNIP-23になれるという意図もあるので紹介に留めます! また、他の関連OSハードウェアプロジェクトのケースもデザインできたらと思っております!
今後ともタコ頭をよろしくお願いいたします。

"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.

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.

2024-12-22 19:16:31この記事は前回の内容を把握している人向けに書いています(特にNostrエクステンション(NIP-07)導入)
手順
- 登録する画像を用意する
- 画像をweb上にアップロードする
- 絵文字セットに登録する
1. 登録する画像を用意する
以下のような方法で用意してください。
- 画像編集ソフト等を使って自分で作成する
- 絵文字作成サイトを使う(絵文字ジェネレーター、MEGAMOJI など)
- フリー画像を使う(いらすとや など)
データ量削減
Nostrでは画像をそのまま表示するクライアントが多いので、データ量が大きな画像をそのまま使うとモバイル通信時などに負担がかかります。
データ量を増やさないためにサイズやファイル形式を変更することをおすすめします。
以下は私のおすすめです。 * サイズ:正方形 128×128 ピクセル、長方形 任意の横幅×128 ピクセル * ファイル形式:webp形式(webp変換おすすめサイト toimg) * 単色、単純な画像の場合:png形式(webpにするとむしろサイズが大きくなる)
その他
- 背景透過画像
- ダークモード、ライトモード両方で見やすい色
がおすすめです。
2. 画像をweb上にアップロードする
よく分からなければ emojito からのアップロードで問題ないです。
普段使っている画像アップロード先があるならそれでも構いません。
気になる方はアップロード先を適宜選んでください。既に投稿されたカスタム絵文字の画像に対して
- 削除も差し替えもできない → emojito など
- 削除できるが差し替えはできない → Gyazo、nostrcheck.meなど
- 削除も差し替えもできる → GitHub 、セルフホスティングなど
これらは既にNostr上に投稿されたカスタム絵文字の画像を後から変更できるかどうかを指します。
どの方法でも新しく使われるカスタム絵文字を変更することは可能です。
同一のカスタム絵文字セットに同一のショートコードで別の画像を登録する形で対応できます。3. 絵文字セットに登録する
emojito から登録します。
右上のアイコン → + New emoji set から新規の絵文字セットを作成できます。
① 絵文字セット名を入力
基本的にカスタム絵文字はカスタム絵文字セットを作り、ひとまとまりにして登録します。
一度作った絵文字セットに後から絵文字を追加することもできます。
② 画像をアップロードまたは画像URLを入力
emojitoから画像をアップロードする場合、ファイル名に日本語などの2バイト文字が含まれているとアップロードがエラーになるようです。
その場合はファイル名を適当な英数字などに変更してください。
③ 絵文字のショートコードを入力
ショートコードは絵文字を呼び出す時に使用する場合があります。
他のカスタム絵文字と被っても問題ありませんが選択時に複数表示されて支障が出る可能性があります。
他と被りにくく長くなりすぎないショートコードが良いかもしれません。
ショートコードに使えるのは半角の英数字とアンダーバーのみです。
④ 追加
Add を押してもまだ作成完了にはなりません。
一度に絵文字を複数登録できます。
最後に右上の Save を押すと作成完了です。
画面が切り替わるので、右側の Options から Bookmark を選択するとそのカスタム絵文字セットを自分で使えるようになります。
既存の絵文字セットを編集するには Options から Edit を選択します。
以上です。

2025-06-16 14:02:26What 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.

【Nostr】Webサイトにビットコインの投げ銭ボタンを設置しよう【Zap】
https://spotlight.soy/detail?article_id=ucd7cbrql/
が前提になってるけど長いので要約すると * ZapするやつはあるけどZap見るやつがないので欲しい * ZapをNostr(の典型的なkind:1クライアント)内だけに留めるのはもったいない * Webサイトの広告うざいからZap(的な何か)で置き換わって欲しいお前だれ?
非エンジニア、非プログラマー
AIにコード出させてるだけ人作った感想
できた
作った感想2
完成してから気付いた本当に作りたかったもの
こういうところにそのままZapを表示できる感じにしたい
(ここまでちゃんとした商業ブログでなく)個人のブログやHPの端っこに「Sponsored by」欄があって名前が表示される感じ
もうZapっていう文字もビットコインっていう文字もNostrも出さなくていいし説明もしなくていいのでは感がある
イメージはWebサイトを対象にしたニコニ広告 + スーパーチャット + 祭りとか神社の奉納者一覧
で思ったのは
個人からの投げ銭なら推し活的なものにしかならないけど
企業がNostrにアカウントを作ってサイトに投げ銭をしたら企業の広告になるんでは!?
~~企業がNostrにアカウントを!?デリヘルしか見たことない!~~今後
思いつき、予定は未定
* ボタン→ダイアログ形式でなくバナー、Embed形式にしてページアクセスですぐ見れるようにする * 多分リレーに負荷がかかるのでなんかする * Zapの文字は出さず「Sponsored by」等にする * 単純な最新順でなくする * 少額Zapをトリミング * 一定期間(一か月など)ごとで金額順にソート * 多分リレーに負荷がかかるのでなんかする * 今は投稿宛てのZapをWebサイト宛てのZapと勝手に言い張ってるだけなのでちゃんとWebサイト宛てのZapにする * NIPの提案が必要 * ウォレットの準拠も必要 * リレー(wss://~)宛てのZapもできてほしい将来
インターネットのすべてに投げ銭をさせろ
おわり
明日は mono さんの Open Sats 申請編 です!!

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.
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 13:37:23There are some amazing places in Georgia to see monarch butterflies! Journey North, an organization that allows users to report monarch sightings, has some great information on the best sightings in Georgia! One great place is Savannah. Known for its historical architecture and beautiful parks, Savannah is also a famous spot to see monarchs! Places such as Wassaw National Wildlife Refuge help with the conservation of monarchs to support them on their migration south. This makes it a great place to observe the monarchs.

2025-06-17 13:09:20ในโลกของเกมออนไลน์ โดยเฉพาะเกมที่มีระบบแลกเปลี่ยนและการซื้อขายกันระหว่างผู้เล่น (player-to-player trading) มีสิ่งหนึ่งที่เกิดขึ้นซ้ำแล้วซ้ำเล่าในแทบทุกเกม นั่นคือ "item หายาก" (rare item) ค่อยๆ กลายเป็นสื่อกลางในการแลกเปลี่ยน มันไม่ใช่แค่ของมีค่าในตัวเองเท่านั้น แต่ยังถูกใช้เสมือนเป็น “เงิน” (currency) ของโลกเสมือนนั้นด้วย
ลองจินตนาการว่าเรากำลังเล่นเกมที่มีระบบ economy ผู้เล่นสามารถหาของจากการล่ามอนสเตอร์ (monster hunting) หรือผ่านเควสต่างๆ สิ่งที่เกิดขึ้นคือบาง item มีโอกาสดรอป (drop rate) ต่ำมากๆ และมีความต้องการสูง สิ่งเหล่านี้แหละที่เริ่ม “มีมูลค่า” ในสายตาของผู้เล่น
เมื่อคนจำนวนมากเริ่มยอมรับว่า item นี้ “แลกของอื่นได้” หรือ “ใช้วัดมูลค่าได้” มันก็กลายเป็นเงินอย่างไม่เป็นทางการโดยอัตโนมัติ
Rare item = เงิน? ได้ไง?
คำตอบง่ายมาก: เพราะมัน หายาก (scarce), เป็นที่ต้องการ (demanded) และ เป็นที่ยอมรับในกลุ่มผู้เล่น (accepted)
ในระบบที่ไม่มีเงินกลางแบบ fix ผู้เล่นจะเริ่มหาสิ่งใดสิ่งหนึ่งมาทำหน้าที่แทน เช่น item ที่ทุกคนรู้ว่าหายากจริง หาไม่ได้ง่ายๆ และมีปริมาณจำกัดในตลาด ระบบนี้เกิดขึ้นเองโดยไม่มี dev หรือระบบของเกมไปบอกว่า "นี่คือเงินนะ"
สิ่งนี้ทำให้เกิด “เศรษฐกิจเสมือน (virtual economy)” ที่ผู้เล่นสร้างขึ้นเองโดยธรรมชาติ และมันคือบทเรียนสำคัญเรื่องเงินในโลกจริง
เศรษฐกิจที่เกิดจาก consensus (ฉันทามติ)
เงิน ไม่ว่าจะในโลกจริงหรือโลกเสมือน มีจุดเริ่มต้นมาจากสิ่งเดียวกันคือ ความเชื่อร่วมกัน (shared belief)
ในเกม ผู้เล่นหลายพันคนพร้อมใจกันเชื่อว่า item ชิ้นนี้ “มีค่า” จึงสามารถใช้แลกทุกอย่างได้ บางคนเอาไปจ้างช่วยผ่านบอส บางคนเอาไปซื้อชุดหรือของตกแต่ง ความน่าสนใจคือ item นั้นอาจไม่ใช่สิ่งที่มี "utility" สูงด้วยซ้ำ บางอันมีไว้โชว์เท่ๆ เท่านั้น แต่มันมี “มูลค่า” เพราะผู้เล่นเห็นว่ามันควรมี
นั่นคือพลังของ consensus และมันคือกลไกเดียวกับที่เงินกระดาษ หรือแม้แต่คริปโตอย่าง Bitcoin ใช้ในการสร้างมูลค่า
ระบบที่ไร้เสถียรภาพ (fragile system)
แต่ economy แบบนี้ไม่ได้สมบูรณ์แบบไปเสียหมด สิ่งหนึ่งที่มักเกิดขึ้นคือ ความเปราะบาง (fragility)
ถ้า item ที่เคยหายากอยู่ๆ กลายเป็นดรอปง่ายขึ้น หรือมี bug ให้ dup ได้ ความเชื่อในความขาดแคลนนั้นจะพังลงทันที และแน่นอนว่า value ที่เคยสูงลิ่วก็ร่วงตามไปด้วย
นอกจากนี้ ยังมีปัจจัยอื่นเช่น การที่ dev แก้กฎ เพิ่มหรือลด supply item โดยไม่แจ้งล่วงหน้า หรือปิด server แบบไม่คาดคิด สิ่งเหล่านี้ทำให้ economy ที่เคยดูมั่นคงต้องสลายไปเพียงชั่วข้ามคืน
นั่นคือจุดที่ virtual economy แตกต่างจาก real-world crypto economy ที่สร้างอยู่บนความโปร่งใสและโค้ดที่ทุกคนตรวจสอบได้
สิ่งที่เราเห็นในเกมไม่ใช่เรื่องบังเอิญ มันคือบทเรียนทางเศรษฐศาสตร์แบบเรียลไทม์ และเรียลฟีล
เรารู้ว่าเงินไม่จำเป็นต้องถูกสร้างโดยรัฐ เรารู้ว่าเงินไม่จำเป็นต้องมีตัวตนแบบธนบัตร และเรารู้ว่า สิ่งใดก็ตามที่หายาก ตรวจสอบได้ และได้รับการยอมรับร่วมกัน — มันสามารถเป็น “เงิน” ได้ แม้จะเป็นแค่ item ในเกมก็ตาม
โลกของเกมจึงเป็น sandbox ที่สอนเราว่า “value” คือสิ่งที่ถูกสร้างขึ้นจากฉันทามติ ไม่ใช่จากอำนาจ
สรุป: เกมคือโลกจำลองของเศรษฐกิจมนุษย์
ไอเทมหายากในเกมที่กลายเป็นเงินไม่ใช่แค่เรื่องบังเอิญ แต่มันคือภาพสะท้อนว่า ความขาดแคลน + ความต้องการ + ความยอมรับ = มูลค่า และนั่นคือหัวใจของระบบเงินทุกแบบ ไม่ว่าจะเป็นทองคำ เงินเฟียต หรือสินทรัพย์ดิจิทัลอย่าง Bitcoin
โลกของเกมไม่ใช่แค่ที่เล่นสนุก แต่มันคือห้องทดลองทางเศรษฐกิจ ที่เปิดเผยให้เราเห็นว่าผู้คนสามารถสร้างระบบเงินได้ด้วยตัวเอง โดยไม่ต้องพึ่งรัฐ ไม่ต้องมีธนาคารกลาง และไม่ต้องมีใคร “อนุมัติ”
มันเริ่มจาก item เล็กๆ ที่คนอยากได้ และจบลงด้วยระบบ economy ที่ทรงพลังยิ่งกว่าที่ dev เคยคาดคิด

2025-06-16 14:02:26The 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.

@ 6bcc27d2:b67d296e
2024-10-21 03:54:32yugoです。 この記事は「Nostrasia2024 逆アドベントカレンダー」10/19の分です。Nostrasiaの当日はリアルタイムで配信を視聴していました。Nostrを使ってアプリケーションの再発明をすべきという発表を聴き、自分だったらどんなものを作ってみたいかを考えて少し調べたり試みたりしたのでその記録を書きます。また、超簡単なものですがおそらく世界初となるvisionOS対応のNostrクライアントをつくってみたので最後の方に紹介します。
アプリケーションを再発明する話があったのは、「What is Nostr Other Stuff?」と題したkaijiさんの発表でした。
Nostrプロトコルを使って既存のアプリケーションを再発明することで、ユーザ体験を損なわずにゆるやかな分散を促すことができ、プロトコルとしてのNostrも成長していくというような内容でした。
自分はまだNostrで何かをつくった経験はなかったので、実装に必要な仕様の知識がほとんどない状態からどのようなアプリケーションをつくってみたいかを考えました。
最初に思いついたのは、Scrapboxのようなネットワーク型のナレッジベースです。自分は最近visionOS勉強会をやっており、勉強会でナレッジを共有する手段としてScrapboxの導入を検討していました。
Nostrコミュニティにも有志によるScrapboxがありますが、Nostrクライアントがあればそれを使うだろうから同じくらいの実用性を備えたクライアントはまだ存在しないのではないかという見立てでした。
長文投稿やpublic chatなどの機能を組み合わせることで実現できるだろうか。そう思っていた矢先、NIP-54のWikiという規格があることを知りました。
https://github.com/nostr-protocol/nips/blob/master/54.md
まだちゃんとは読めていないですが、Scrapboxもwikiソフトウェアだし参考になりそうと思っています。正式な仕様に組み込まれていないようで、採用しているクライアントはfiatjafによるリファレンス実装(?)のwikistrくらいしか見つかりませんでした。
Scrapboxのようなナレッジベースを志向するNostrクライアントがあれば、後述するvisionOS対応クライアントの存在もありアカウントを使いまわせて嬉しいので試してみたいです。もし他にも似たようなサービスをどなたか知っていたら教えてください。
また現在は、勉強会やワークショップ、ハッカソンなどのコラボレーションワークを支援するためのツールを自分たちでも開発しています。Apple Vision Proに搭載されているvisionOSというプラットフォームで動作します。
https://image.nostr.build/14f0c1b8fbe5ce7754825c01b09280a4c22f87bbf3c2fa6d60dd724f98919c34.png
この画面で自分が入りたいスペースを選んで共有体験を開始します。
スライドなどのコンテンツや自らのアバターを同期させることで、遠隔地にいてもまるでオフラインかのように同じ空間を共有することが可能になります。
https://image.nostr.build/cfb75d3db2a9b9cd39f502d6426d5ef4f264b3d5d693b6fc9762735d2922b85c.jpg
ということなので、急遽visionOS対応のクライアントを作ってみました。検索しても1つも事例が出てこなかったので多分まだ世界で実装しているアプリはないのではないでしょうか。
とはいえ、クライアントを名乗っているもののまだ大した機能はなく、リレーからデータを取得するだけの読み取り専用です。
https://image.nostr.build/96e088cc6a082528682989ccc12b4312f9cb6277656e491578e32a0851ce50fe.png
画像では自分のプロフィールデータをリレーから取得しています。
まだどのライブラリもvisionOSに対応していなかったりで手こずったものの仕様の勉強になりました。
ただvisionOSアプリはiOSアプリ同様NIP-7が使えないので秘密鍵を自分で保管しなくてはならず、今後どう対処すべきかわかりかねています。これから時間ある時に少しずつ調べていこうと思っていますが、ネイティブアプリの秘密鍵周りはあまりリソースが多くないようにも感じました。もしどなたかその辺の実装に詳しい方いたら教えていただけると嬉しいです。
準備ができたらそのうちコードも公開したいと思っています。
これから少しずつ色んな機能を実装しながらNostrで遊んでいきたいです!

2025-06-16 14:02:25The 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 13:08:24ในการกล่าวสุนทรพจน์หลักในงาน Bitcoin 2025 ไมเคิล เซย์เลอร์ (Michael Saylor) นักเคลื่อนไหวชื่อดังด้านบิตคอยน์และซีอีโอของบริษัท MicroStrategy ได้บรรยายหัวข้อที่ทรงพลังชื่อว่า "21 วิธีสู่ความมั่งคั่ง" เขาได้เสนอเส้นทางเชิงกลยุทธ์สำหรับบุคคลทั่วไป ครอบครัว และธุรกิจขนาดเล็ก ในการบรรลุความมั่งคั่งทางการเงินผ่านบิตคอยน์
ต่างจากคำพูดก่อนหน้าของเขาที่มุ่งเป้าไปที่สถาบันและรัฐบาล คำพูดนี้ถูกออกแบบมาสำหรับผู้คนทั้ง 8 พันล้านคน บนโลก โดยเน้นขั้นตอนปฏิบัติที่สามารถใช้บิตคอยน์เป็นทรัพย์สินเปลี่ยนชีวิตอย่างแท้จริง ด้านล่างนี้คือการสำรวจเชิงลึกใน 21 หลักการ ของเซย์เลอร์ ซึ่งเปรียบเสมือนพิมพ์เขียวในการสร้างความมั่งคั่งในยุคดิจิทัล:
1. ความชัดเจน (Clarity): เข้าใจบิตคอยน์ในฐานะทุนที่สมบูรณ์แบบ เซย์เลอร์เริ่มต้นด้วยแนวคิดเรื่อง “ความชัดเจน” โดยเน้นว่าบิตคอยน์คือ "ทุนที่ถูกออกแบบอย่างสมบูรณ์" ซึ่งไม่สามารถถูกทำลายหรือดัดแปลงได้ ความเข้าใจนี้เป็นพื้นฐานสำคัญในการยอมรับศักยภาพของบิตคอยน์ในฐานะรากฐานของความมั่งคั่ง
2. ความเชื่อมั่น (Conviction): ศรัทธาในศักยภาพการเติบโตเหนือกว่า เซย์เลอร์ยืนยันว่าบิตคอยน์ถูกออกแบบมาให้เติบโตเร็วกว่าสินทรัพย์ทั่วไป เช่น หุ้น ทองคำ หรืออสังหาริมทรัพย์ การมีความเชื่อมั่นอย่างแท้จริงเป็นสิ่งจำเป็นต่อการให้ความสำคัญกับบิตคอยน์เหนือการลงทุนแบบดั้งเดิม
3. ความกล้า (Courage): ยอมรับความเสี่ยงทางการเงินอย่างชาญฉลาด บิตคอยน์คือการยอมรับความเสี่ยงที่คำนวณได้อย่างชาญฉลาด ไม่ใช่ความกลัวหรือการพนัน ผู้ที่ "เติมเชื้อไฟ" ให้กับระบบนี้คือผู้ที่เปลี่ยนเงินเฟียตหรือสินทรัพย์ด้อยค่ามาเป็นบิตคอยน์
4. ความร่วมมือ (Cooperation): ผนึกกำลังในครอบครัวเพื่อความแข็งแกร่ง เมื่อครอบครัวร่วมมือกัน ศักยภาพในการสร้างความมั่งคั่งจะเพิ่มทวีคูณ เซย์เลอร์เสนอให้ครอบครัวผสานความสามารถและทรัพยากร เพื่อผลักดันกันและกันสู่อนาคตที่ดีกว่า
5. ความสามารถ (Capability): เชี่ยวชาญปัญญาประดิษฐ์ ในปี 2025 AI เป็นกุญแจสำคัญในการปลดล็อกโอกาสทางการเงินระดับสูง โดยที่บุคคลทั่วไปสามารถเข้าถึงคำแนะนำจากทนาย นักบัญชี หรือผู้เชี่ยวชาญ โดยไม่เสียค่าใช้จ่าย
6. การจัดวางโครงสร้าง (Composition): สร้างนิติบุคคลเพื่อป้องกันและขยายผล การตั้งบริษัท ทรัสต์ หรือโครงสร้างทางกฎหมาย เช่น IRA หรือ 401(k) คือวิธีเพิ่มประสิทธิภาพในการลงทุนบิตคอยน์อย่างปลอดภัยและถูกกฎหมาย
7. สัญชาติทางเศรษฐกิจ (Citizenship): เลือกฐานภาษีอย่างชาญฉลาด เลือกอยู่ในพื้นที่หรือประเทศที่เป็นมิตรกับบิตคอยน์ เช่น ฟลอริดา หรือประเทศอย่างสิงคโปร์ เพื่อลดภาระภาษีและเพิ่มเสถียรภาพระยะยาว
8. ความสุภาพ (Civility): เคารพโครงสร้างอำนาจ ไม่จำเป็นต้องล้มล้างระบบเก่า เพียงแค่รู้จักเคารพอำนาจและสร้างพันธมิตรในทางที่สร้างสรรค์เพื่อเดินหน้ากับบิตคอยน์ได้
9. การใช้บริษัท (Corporation): บริษัทคือเครื่องจักรสร้างความมั่งคั่ง บริษัทสามารถใช้ประโยชน์จากระบบการเงินและภาษีได้ดีกว่าปัจเจกบุคคล จึงควรจัดตั้งนิติบุคคลเพื่อลงทุนในบิตคอยน์อย่างจริงจัง
10. โฟกัส (Focus): อย่าหลงทาง อย่าวอกแวกไปกับธุรกิจเสี่ยงสูงหรือเหรียญอื่น ๆ เพราะบิตคอยน์มีประวัติผลตอบแทนสูงอย่างสม่ำเสมอ
11. การมีส่วนร่วม (Equity): ร่วมมือกับนักลงทุน ให้ผู้อื่นร่วมลงทุนในกิจการของคุณ เช่น หมอฟันอาจขายหุ้นบางส่วนของคลินิกเพื่อนำเงินไปลงทุนในบิตคอยน์
12. เครดิต (Credit): ใช้หนี้เป็นเครื่องมือ กู้เงินดอกเบี้ยต่ำและลงทุนในบิตคอยน์ที่มีแนวโน้มเติบโตสูง เพื่อทำกำไรจากส่วนต่างระหว่างดอกเบี้ยกับผลตอบแทน
13. การปฏิบัติตามกฎ (Compliance): ทำตามกฎหมาย สร้างบริษัทที่สอดคล้องกับกฎระเบียบเพื่อขยายเงินทุนได้อย่างมั่นคงและปลอดภัย
14. การระดมทุน (Capitalization): หาเงินลงทุนอย่างต่อเนื่อง ไม่ว่าจะจากการขายหุ้น หรือรีไฟแนนซ์ทรัพย์สินส่วนตัว ทุกโอกาสคือช่องทางในการระดมทุนและลงทุนต่อในบิตคอยน์
15. การสื่อสาร (Communication): โปร่งใสและจริงใจ การเปิดเผยแผนและเป้าหมายอย่างชัดเจนจะสร้างความไว้วางใจจากนักลงทุน พนักงาน และลูกค้า
16. ความมุ่งมั่น (Commitment): อยู่กับบิตคอยน์ ไม่หลงทาง หลีกเลี่ยงเหรียญอื่น ๆ หรือโปรเจกต์ที่ไม่มั่นคง ยึดมั่นในบิตคอยน์เพื่อเสถียรภาพระยะยาว
17. การลงมือทำ (Delivery): ลงมือจริงอย่างแม่นยำ ไม่ใช่แค่คิด แต่ต้องทำอย่างมีประสิทธิภาพ สม่ำเสมอ และไม่ประมาท
18. การปรับตัว (Adaptation): พร้อมเปลี่ยนแปลงเมื่อจำเป็น ระบบใด ๆ ก็มีวันล้มเหลว การปรับตัวตามสถานการณ์คือสิ่งที่ทำให้ยืนหยัดได้ในระยะยาว
19. วิวัฒนาการ (Evolution): เติบโตจากจุดแข็ง ขยายธุรกิจจากสิ่งที่คุณเชี่ยวชาญ แทนที่จะพยายามเริ่มสิ่งใหม่จากศูนย์
20. การเผยแพร่ (Advocacy): เป็นกระบอกเสียงเพื่อเสรีภาพทางเศรษฐกิจ บอกต่อและสอนผู้อื่นให้เข้าใจบิตคอยน์ เพื่อขยายเครือข่ายแห่งความมั่งคั่ง
21. ความเอื้อเฟื้อ (Generosity): แบ่งปันความสำเร็จ การช่วยเหลือครอบครัว ชุมชน และพนักงาน ด้วยทรัพยากรที่คุณมี จะสร้างความสุขทั้งต่อตัวคุณและโลก
เซย์เลอร์จบท้ายด้วยคำของซาโตชิ นากาโมโตะว่า:
“มันอาจจะดีถ้ามี bitcoin ไว้บ้าง เผื่อว่ามันจะกลายเป็นสิ่งสำคัญในอนาคต”
หลังจาก 16 ปีแห่งการเติบโตและมูลค่าตลาดกว่า 2 ล้านล้านดอลลาร์ หลักการทั้ง 21 ข้อนี้คือพิมพ์เขียวแห่งเสรีภาพทางการเงิน ที่รวมเอาความชัดเจน ความกล้า และเครื่องมืออย่าง AI, การจัดตั้งบริษัท และเครดิต เข้าด้วยกัน เพื่อให้ทุกคนสามารถใช้บิตคอยน์สร้างอนาคตที่ดีกว่าได้

2024-09-06 12:49:46Nostr: a quick introduction, attempt #2
Nostr doesn't subscribe to any ideals of "free speech" as these belong to the realm of politics and assume a big powerful government that enforces a common ruleupon everybody else.
Nostr instead is much simpler, it simply says that servers are private property and establishes a generalized framework for people to connect to all these servers, creating a true free market in the process. In other words, Nostr is the public road that each market participant can use to build their own store or visit others and use their services.
(Of course a road is never truly public, in normal cases it's ran by the government, in this case it relies upon the previous existence of the internet with all its quirks and chaos plus a hand of government control, but none of that matters for this explanation).
More concretely speaking, Nostr is just a set of definitions of the formats of the data that can be passed between participants and their expected order, i.e. messages between clients (i.e. the program that runs on a user computer) and relays (i.e. the program that runs on a publicly accessible computer, a "server", generally with a domain-name associated) over a type of TCP connection (WebSocket) with cryptographic signatures. This is what is called a "protocol" in this context, and upon that simple base multiple kinds of sub-protocols can be added, like a protocol for "public-square style microblogging", "semi-closed group chat" or, I don't know, "recipe sharing and feedback".

2025-06-16 14:02:25People 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.

Ich möchte gerne mit euch teilen, an welchen Konzepten ich arbeite, um die öffentliche Bildungsinfrastruktur mit Hilfe von Nostr zugänglicher und offener zu gestalten. Ich arbeite im Bereich öffentlicher Bildungsinfrastrukturen, besonders im Feld von Open Educational Resources (#OER). OER sind offen lizenzierte Bildungsmaterialien, die mit einer offenen Lizenz, meist einer Creative Commons Lizenz, versehen sind (CC-0, CC-BY, CC-BY-SA). Durch die klare und offene Lizenzierung ist es leicht möglich, die Lernmaterialien auf die individuellen Bedarfe anzupassen, sie zu verbessern und sie erneut zu veröffentlichen.
Seit vielen Jahren wird einerseits die Entwicklung freier Bildungsmaterialien gefördert, andererseits werden Plattformen, insbesondere Repositorien gefördert, die diese Materialien verfügbar machen sollen. Denn irgendwo müssen diese Materialien zur Verfügung gestellt werden, damit sie auch gefunden werden können.
Das klappt allerdings nur so mittelgut.
Herausforderungen
Nach vielen Jahren Förderung kann die einfache Frage: "Wo kann ich denn mein OER-Material bereitstellen" nicht einfach beantwortet werden. Es gibt Services, bei denen ich mein OER hochladen kann, jedoch bleibt es dann eingeschlossen in dieser Plattform und wird nicht auf anderen Plattformen auffindbar. Außerdem sind diese Services häufig an bestimmte Bildungskontexte gebunden oder geben Content erst nach einer Qualitätsprüfung frei. Dies führt dazu, dass ein einfaches und gleichzeitig öffentliches Teilen nicht möglich ist.
Diese und weitere Herausforderungen haben ihren Ursprung darin, dass Service und Infrastruktur in der Architektur öffentlichen Bildungsarchitektur ungünstig vermischt werden. Als Infrastruktur verstehe ich hier die Bereitstellung einer öffentlichen und offen zugänglichen Bildungsinfrastruktur, auf der Daten ausgetauscht, also bereitgestellt und konsumiert werden können. Jedoch existiert eine solche Infrstruktur momentan nicht unabhängig von den Services, die auf ihr betrieben werden. Infrastrukturbetreiber sind momentan gleichzeitig immer Servicebetreiber. Da sie aber die Hand darüber haben wollen, was genau in ihrem Service passiert (verständlich), schränken sie den Zugang zu ihrer Infrastruktur mit ein, was dazu führt, dass sie Lock-In Mechanismen großer Medienplattformen in der kleinen öffentlichen Bildungsinfrastruktur replizieren.
Es ist in etwas so, als würde jeder Autobauer auch gleichzeitig die Straßen für seine Fahrzeuge bauen. Aber halt nur für seine Autos.
Anhand einiger beispielhafter Services, die bestehende Plattformen auf ihren Infrastrukturen anbieten, möchte ich die Herausforderungen aufzeigen, die ich im aktuellen Architekturkonzept sehe:
- Upload von Bildungsmaterial
- Kuration: Zusammenstellung von Listen, Annotation mit Metadaten
- Crawling, Indexierung und Suche
- Plattfformübergreifende Kollaboration in Communities -> Beispiel: Qualitätssicherung (was auch immer das genau bedeutet)
- KI- Services -> Beispiel: KI generierte Metadaten für BiIdungsmaterial
Material Upload
Der Service "Material-Upload" oder das Mitteilen eines Links zu einem Bildungsmaterial wird von verschiedenen OER-Pattformen bereitgestellt (wirlernenonline.de, oersi.org, mundo.schule).
Dies bedeutet konkret: Wenn ich bei einer der Plattformen Content hochlade, verbleibt der Content in der Regel auch dort und wird nicht mit den anderen Plattformen geteilt. Das Resultat für die User: Entweder muss ich mich überall anmelden und dort mein Material hochladen (führt zu Duplikaten) oder damit leben, dass eben nur die Nutzer:innen der jeweiligen Plattform meinen Content finden können.
Der "Open Educational Resource Search Index" (OERSI) geht diese Herausforderung an, indem die Metadaten zu den Bildungsmaterialien verschiedener Plattformen in einem Index bereitgestellt werden. Dieser Index ist wiederum öffentlich zugänglich, sodass Plattformen darüber auch Metadaten anderer Plattformen konsumieren können. Das ist schon sehr gut. Jedoch funktioniert das nur für Plattformen, die der OERSI indexiert und für alle anderen nicht. Der OERSI ist auf den Hochschulbereich fokussiert, d.h. andere Bildungskontexte werden hier ausgeschlossen. Der Ansatz für jeden Bildungsbereich einen passenden "OERSI" daneben zustellen skaliert und schlecht und es bleibt die Herausforderung bestehen, dass für jede Quelle, die indexiert werden soll, ein entsprechender Importer/Crawler geschrieben werden muss.
Dieser Ansatz (Pull-Ansatz) rennt den Materialien hinterher.
Es gibt jedoch noch mehr Einschränkungen: Die Plattformen haben sich jeweils auf spezifische Bildungskontexte spezialisiert. D.h. auf die Fragen: Wo kann ich denn mein OER bereitstellen, muss immer erst die Gegenfrage: "Für welchen Bildungsbereich denn?" beantwortet werden. Wenn dieser außerhalb des allgemeinbildendenden Bereichs oder außerhalb der Hochschule liegt, geschweige denn außerhalb des institutionellen Bildungsrahmens, wird es schon sehr, sehr dünn. Kurzum:
- Es ist nicht einfach möglich OER bereitzustellen, sodass es auch auf verschiedenen Plattformen gefunden werden kann.
Kuration
Unter Kuration verstehe ich hier die Zusammenstellung von Content in Listen oder Sammlungs ähnlicher Form sowie die Annotation dieser Sammlungen oder des Contents mit Metadaten.
Einige Plattformen bieten die Möglichkeit an, Content in Listen einzuordnen. Diese Listen sind jedoch nicht portabel. Die Liste, die ich auf Plattform A erstelle, lässt sich nicht auf Plattform B importieren. Das wäre aber schön, denn so könnten die Listen leichter auf anderen Plattformen erweitert oder sogar kollaborativ gestaltet werden, andererseits werden Lock-In-Effekte zu vermieden.
Bei der Annotation mit Metadaten treten verschiedene zentralisierende Faktoren auf. In der momentanen Praxis werden die Metadaten meist zum Zeitpunkt der Contentbereitstellung festgelegt. Meist durch eine Person oder Redaktion, bisweilen mit Unterstützung von KI-Services, die bei der Metadateneingabe unterstützen. Wie aber zusätzliche eigene Metadaten ergänzen? Wie mitteilen, dass dieses Material nicht nur für Biologie, sondern auch für Sport in Thema XY super einsetzbar wäre? Die momentanen Ansätze können diese Anforderung nicht erfüllen. Sie nutzen die Kompetenz und das Potential ihrer User nicht.
- Es gibt keine interoperablen Sammlungen
- Metadaten-Annotation ist zentralisiert
- User können keine eigenen Metadaten hinzufügen
Crawling, Indexierung und Suche
Da die Nutzer:innen nicht viele verschiedene Plattformen und Webseiten besuchen wollen, um dort nach passendem Content zu suchen, crawlen die "großen" OER-Aggregatoren diese, um die Metadaten des Contents zu indexieren. Über verschiedene Schnittstellen oder gerne auch mal über das rohe HTML. Letztere Crawler sind sehr aufwändig zu schreiben, fehleranfällig und gehen bei Design-Anpassungen der Webseite schnell kaputt, erstere sind etwas stabiler, solange sich die Schnittstelle nicht ändert. Durch den Einsatz des Allgemeinen Metadatenprofils für Bildungsressourcen (AMB) hat sich die Situation etwas verbessert. Einige Plattformen bieten jetzt eine Sitemap an, die Links zu Bildungsmaterial enthalten, die wiederum eingebettet
script
-tags vom Typapplication/ld+json
enthalten, sodass die Metadaten von dort importiert werden können.Beispiel: e-teaching.org bietet hier eine Sitemap für ihre OER an: https://e-teaching.org/oer-sitemap.xml und auf den jeweiligen Seiten findet sich ein entsprechendes script-Tag.
Das ist schon viel besser, aber da geht noch mehr:
Zunächst ist dieser Ansatz nur für Plattformen und Akteure praktikabel, die über IT-Ressourcen verfügen, um entsprechende Funktionalitäten bei sich einbauen zu können. Lehrende können dies nicht einfach auf ihrem privaten Blog oder ähnliches umsetzen. Zum anderen besteht immer noch ein Discovery Problem. Ich muss nach wie vor wissen, wo ich suchen muss. Ich muss die Sitemaps kennen, sonst finde ich nichts. Statt eines Ansatzes, bei dem Akteure eigenständig mitteilen können, dass sie neuen Content haben (Push-Ansatz), verfolgen wir derzeit einen Ansatz, bei dem jede Plattform für sich Content im Pull-Verfahren akquiriert. Dies führt an vielen Stellen zu Doppelarbeiten, ist ineffizient (mehrere Personen bauen genau die gleichen Crawler, aber halt immer für ihre Plattform) und schliesst vor allem kleine Akteure aus (lohnt es sich einen Crawler zu programmieren, wenn die Webseite "nur" 50 Materialien bereitstellt?).
Anstatt erschlossene Daten zu teilen, arbeiten die Plattformen für sich oder stellen es höchstens wieder hinter eigenen (offenen oder geschlossenen) Schnittstellen bereit. Das ist wohl nicht das, was wir uns unter einer offenen und kollaborativen Gemeinschaft vorstellen, oder?
Bei der Suche stehen wir vor ähnlichen Herausforderungen, wie bereits oben geschildert. Obwohl verschiedene OER-Aggregatoren in Form von Repositorien oder Referatorien bereits viele der "kleineren" Plattformen indexieren und somit eine übergreifende Suche anbieten, ist es nicht möglich, diese Aggregatoren gemeinsam zu durchsuchen. Dies führt im Endeffekt dazu, dass die User wieder verschiedene Plattformen ansteuern müssen, wenn sie den gesamten OER-Fundus durchsuchen wollen.
- An vielen Stellen wird Content doppelt erschlossen, aber immer für die eigene Plattform
- Es gibt keinen geteilten Datenraum, in den Akteure Content "pushen" können
- Es gibt keine plattformübergreifenden Suchmöglichkeiten
Plattformübergreifende Kollaboration
Das wäre schön, oder? Mir ist schleierhaft, wie #OEP (Open Educational Practices, genaue Definition durch die Community steht noch aus) ohne funktionieren soll. Aber es gibt meines Wissens nach nicht mal Ansätze, wie das technisch umgesetzt werden soll (oder doch? let me hear).
Ein Szenario für solche plattformübergreifende Kollaboration könnte Qualitätssicherung sein. Gesetzt, dass sich zwei Plattformen / Communities auf etwas verständigt haben, dass sie als "Qualität" bezeichnen, wie aber dieses Gütesiegel nun an den Content bringen?
Plattform A: Na, dann kommt doch alle zu uns. Hier können wir das machen und dann hängt auch ein schönes Badge an den Materialien.
Plattform B: Ja, aber dann hängt es ja nicht an unseren Materialien. Außerdem wollen/müssen wir bei uns arbeiten, weil welche Existenzberechtigung hat denn meine Plattform noch, wenn wir alles bei dir machen?
- Obwohl nun #OEP in aller Munde sind, gibt es keine technischen Ansätze, wie (plattformübergreifende) Kollaboration technisch abgebildet werden kann
KI-Services
Was ist heute schon komplett ohne das Thema KI zu erwähnen? Mindestens für den nächsten Förderantrag muss auch irgendetwas mit KI gemacht werden...
Verschiedene Projekte erarbeiten hilfreiche und beeindruckende KI-Services. Beispielsweise, um die Annotation von Content mit Metadaten zu erleichtern, Metadaten automatisch hinzuzufügen, Content zu bestimmten Themen zu finden oder (halb-)automatisch zu Sammlungen hinzuzufügen. Aber (vielleicht habt ihr es schon erraten): Funktioniert halt nur auf der eigenen Plattform. Vermutlich, weil die Services nah am plattformeigenen Datenmodell entwickelt werden. Und da die Daten dieses Silo nicht verlassen, passt das schon. Das führt dazu, dass an mehreren Stellen die gleichen Services doppelt entwickelt werden.
- KI-Services funktionieren oft nur auf der Plattform für die sie entwickelt werden
Zusammenfassung der Probleme
Wir machen übrigens vieles schon sehr gut (Einsatz des AMB, Offene Bidungsmaterialien, wir haben eine großartige Community) und jetzt müssen wir halt weiter gehen.
(Die OER-Metadatengruppe, die das Allgemeine Metadatenprofil für Bildungsressourcen (AMB) entwickelt hat, bekommt für ihre Arbeit keine direkte Förderung. Gleichzeitig ist sie eine zentrale Anlaufstelle für alle, die mit Metadaten in offenen Bildungsinfrastukturen hantieren und das Metadatenprofil ist eines der wenigen Applikationsprofile, das öffentlich einsehbar, gut dokumentiert ist und Validierungsmöglichkeiten bietet.)
Betrachten wir die gesamten Plattformen und die beschriebenen Herausforderungen aus der Vogelperspektive, so lassen sich drei ineinander verschränkte Kernbestandteile unterscheiden, die helfen, die beschriebenen Probleme besser zu verstehen:
- User
- Service
- Daten
User: Auf (fast) allen Plattformen agieren User. Sie laden Material hoch, annotieren mit Metadaten, sind in einer Community, suchen Content usw. Egal, ob sie sich einloggen können/müssen, irgendetwas bieten wir unseren Usern an, damit sie daraus hoffentlich Mehrwerte ziehen
Service: Das ist dieses irgendetwas. Die "Webseite", die Oberfläche, das, wo der User klicken und etwas tun kann. Es ist das, was den Daten oft eine "visuelle" Form gibt. Der Service ist der Mittler, das Interface zwischen User und Daten. Mithilfe des Services lassen sich Daten erzeugen, verändern oder entfernen (Es gibt natürlich auch viele nicht-visuelle Services, die Interaktion mit Daten ermöglichen, aber für die meisten normalen Menschen, gibt es irgendwo was zu klicken).
Daten: Die Informationen in strukturierter maschinenlesbarer Form, die dem User in gerenderter Form durch einen Service Mehrwerte bieten können. Ungerenderte Daten können wir schwieirg erfassen (wir sind ja nicht Neo). Das können entweder die Metadaten zu Bildungmaterialien sein, die Materialien selbst, Profilinformationen, Materialsammlungen o.ä.
Meines Erachtens nach haben viele der oben beschriebenen Herausforderungen ihren Ursprung darin, dass die drei Kernbestandteile User, Service, Daten ungünstig miteinander verbunden wurden. Was kein Vorwurf sein soll, denn das ist genau die Art und Weise, wie die letzten Jahre (Jahrzehnte?) Plattformen immer gebaut wurden:
- User, Service und Daten werden in einer Plattform gebündelt
Das heisst durch meinen Service agieren die User mit den Daten und ich kann sicherstellen, dass in meiner kleinen Welt alles gut miteinander funktioniert. Sinnvoll, wenn ich Microsoft, Facebook, X oder ähnliches bin, weil mein Geschäftsmodell genau darin liegt: User einschließen (lock-in), ihnen die Hohheit über ihren Content nehmen (oder kannst du deine Facebook Posts zu X migrieren?) und nach Möglichkeit nicht wieder rauslassen.
Aber unsere Projekte sind öffentlich. Das sind nicht die Mechanismen, die wir replizieren sollten. Also was nun?
Bildungsinfrasstrukturen auf Basis des Nostr-Protokolls
Nostr
Eine pseudonyme Person mit dem Namen "fiatjaf" hat 2019 ein Konzept für ein Social Media Protokoll "Nostr - Notes and Other Stuff Transmitted By Relays" wie folgt beschrieben:
It does not rely on any trusted central server, hence it is resilient, it is based on cryptographic keys and signatures, so it is tamperproof, it does not rely on P2P techniques, therefore it works.
Fiatjaf, 2019
Die Kernbestandsteile des Protokolls bestehen aus:
- JSON -> Datenformat
- SHA256 & Schnorr -> Kryptographie
- Websocket -> Datenaustausch
Und funktionieren tut es so:
User besitzen ein "Schlüsselpaar": einen privaten Schlüssel (den behälst du für dich, nur für dich) und einen öffentlichen Schlüssel, den kannst du herumzeigen, das ist deine öffentliche Identität. Damit sagst du anderen Usern: Hier schau mal, das bin ich. Die beiden Schlüssel hängen dabei auf eine "magische" (kryptografische) Weise zusammen: Der öffentliche Schlüssel lässt sich aus dem privaten Schlüssel generieren, jedoch nicht andersherum. D.h. falls du deinen öffentlichen Schlüssel verlierst: Kein Problem, der lässt sich immer wieder herstellen. Wenn du deinen privaten Schlüssel verlierst: Pech gehabt, es ist faktisch unmöglich, diesen wieder herzustellen.
Die Schlüsselmagie geht jedoch noch weiter: Du kannst mit deinem privaten Schlüssel "Nachrichten" signieren, also wie unterschreiben. Diese Unterschrift, die du mit Hilfe des privaten Schlüssels erstellst, hat eine magische Eigenschaft: Jeder kann mithilfe der Signatur und deinem öffentlichen* Schlüssel nachprüfen, dass nur die Person, die auch den privaten Schlüssel zu diesem öffentlichen Schlüssel besitzt, diese Nachricht unterschrieben haben kann. Magisch, richtig? Verstehst du nicht komplett? Nicht schlimm, du benutzt es bereits vermutlich, ohne dass du es merkst. Das ist keine fancy neue Technologie, sondern gut abgehangen und breit im Einsatz.
Merke: User besitzen ein Schlüsselpaar und können damit Nachrichten signieren.
Dann gibt es noch die Services. Services funktionieren im Grunde wie bereits oben beschrieben. Durch sie interagieren die User mit Daten. Aber bei Nostr ist es ein kleines bisschen anders als sonst, denn: Die Daten "leben" nicht in den Services. Aber wo dann?
Wenn ein User einen Datensatz erstellt, verändert oder entfernen möchte, wird dieses "Event" (so nennen wir das bei Nostr) mit deinem privaten Schlüssel signiert (damit ist für alle klar, nur du kannst das gemacht haben) und dann mehrere "Relays" gesendet. Das sind die Orte, wo die Daten gehalten werden. Wenn ein User sich in einen Service einloggt, dann holt sich der Service die Daten, die er braucht von diesen Relays. User, Service und Daten sind also entkoppelt. Der User könnte zu einem anderen Service wechseln und sich dieseleben Daten von den Relays holen. Keine Lock-In Möglichkeiten.
Merke: User, Service und Daten sind entkoppelt.
Zuletzt gibt es noch die Relays. Relays sind Orte. Es sind die Orte, zu denen die Events, also die Daten der User, ihre Interaktionen, gesendet und von denen sie angefragt werden. Sie sind sowas wie das Backend von Nostr, allerdings tun sie nicht viel mehr als das: Events annehmen, Events verteilen. Je nach Konfiguration dürfen nur bestimmte User auf ein Relay schreiben oder davon lesen.
Das Protokoll ist von seinem Grunddesign auf Offenheit und Interoperabilität ausgelegt. Keine Registrierung ist nötig, sondern nur Schlüsselpaare. Durch kryptografische Verfahren kann dennoch die Authentizitität eines Events sichergestellt werden, da nur die Inhaberin des jeweiligen Schlüsselpaares dieses Event so erstellen konnte. Die Relays sorgen dafür die Daten an die gewünschten Stellen zu bringen und da wir mehr als nur eines benutzen, haben wir eine gewisse Ausfallsicherheit. Da die Daten nur aus signierten JSON-Schnipseln bestehen, können wir sie leicht an einen anderen Ort kopieren, im Falle eines Ausfalls. Durch die Signaturen ist wiederum sichergestellt, dass zwischendurch keine Veränderungen an den Daten vorgenommen wurden.
Beispiel: Ein Nostr Event
Hier ein kleiner technischer Exkurs, der beschreibt, wie Nostr Events strukturiert sind. Falls dich die technischen Details nicht so interessieren, überspringe diesen Abschnitt ruhig.
Jedes Nostr Event besitzt die gleiche Grundstruktur mit den Attributen:
id
: Der Hash des Eventspubkey
: Der Pubkey des Urhebers des Eventscreated_at
: Der Zeitstempel des Eventskind
: Der Typ des Eventstags
: Zusätzliche Metadaten für das Event können in diesem Array hinterlegt werdencontent
: Der textuelle Inhalt eines Eventssig
: Die Signatur des Events, um die Integrität der Daten zu überprüfen
json { "id": <32-bytes lowercase hex-encoded sha256 of the serialized event data>, "pubkey": <32-bytes lowercase hex-encoded public key of the event creator>, "created_at": <unix timestamp in seconds>, "kind": <integer between 0 and 65535>, "tags": [ [<arbitrary string>...], // ... ], "content": <arbitrary string>, "sig": <64-bytes lowercase hex of the signature of the sha256 hash of the serialized event data, which is the same as the "id" field> }
Die verwendeten Eventtypen sowie die existierenden Spezifikationen lassen sich unter https://github.com/nostr-protocol/nips/ einsehen.
Wichtig ist auch: Du kannst einfach anfangen, Anwendungen zu entwickeln. Die Relays werden alle Events akzeptieren, die dem o.g. Schema folgen. Du musst also niemanden um Erlaubnis fragen oder warten, bis deine Spezifikation akzeptiert und hinzugefügt wurde.
You can just build things.
Exkurs: Nostr für Binärdaten - Blossom
Ja, aber... das ist doch nur für textbasierte Daten geeignet? Was ist denn mit den Binärdaten (Bilder, Videos, PDFs, etc)
Diese Daten sind oft recht groß und es wurde sich auf das Best-Practice geeignet, diese Daten nicht auf Relays abzulegen, sondern einen besser geeigneten Publikationsmechanismus für diese Datentypen zu finden. Der Ansatz wird als "Blossom - Blobs stored simply on mediaservers" bezeichnet und ist recht unkompliziert.
Blossom Server (nichts anderes als simple Medienserver) nutzen Nostr Schlüsselpaare zur Verwaltung Identitäten und zum Signieren von Events. Die Blobs werden über ihren sha256 Hash identifiziert. Blossom definiert einige standardisierte Endpunkte, die beschreiben wie Medien hochgeladen werden können, wie sie konsumiert werden können usw.
Die Details, wie Authorisierung und die jeweiligen Endpunkte funktionieren, werden in der genannten Spezifikation beschrieben.
Nostr 🤝 Öffentliche Bildungsinfrastrukturen
Wie könnten Herausforderungen gelöst werden, wenn wir Nostr als Basis für die öffentliche Bildungsinfrastruktur einsetzen?
Material-Upload
- Es ist nicht einfach möglich OER bereitzustellen, sodass es auch auf verschiedenen Plattformen gefunden werden kann.
Mit Nostr als Basis-Infrastruktur würden die Metadaten und die Binärdaten nicht an den Service gekoppelt sein, von dem aus sie bereitgestellt wurden. Binärdaten können auf sogenannten Blossom-Servern gehostet werden. Metadaten, Kommentare und weitere textbasierte Daten werden über die Relay-Infrastruktur verteilt. Da Daten und Service entkoppelt sind, können die OER Materialien von verschiedenen Anwendungen aus konsumiert werden.
Kuration
- Es gibt keine interoperablen Sammlungen
- Metadaten-Annotation ist zentralisiert
- User können keine eigenen Metadaten hinzufügen
Sammlungen sind per se interoperabel. Auf Protokollebene ist definiert, wie Listen funktionieren. Die Annotation mit Metadaten ist an keiner Stelle zentralisiert. Das Versprechen der RDF-Community "Anyone can say anything about any topic" wird hier verwirklicht. Ich muss mir ja nicht alles anhören. Vielleicht konsumiere ich nur Metadaten-Events bestimmter Redaktionen oder User. Vielleicht nur diejenigen mit einer Nähe zu meinem sozialen Graphen. Jedenfalls gibt es die Möglichkeit für alle User entsprechende Metadaten bereit zu stellen.
Crawling, Indexierung und Suche * An vielen Stellen wird Content doppelt erschlossen, aber immer für die eigene Plattform * Es gibt keinen geteilten Datenraum, in den Akteure Content "pushen" können * Es gibt keine plattformübergreifenden Suchmöglichkeiten
Keine Doppelerschließungen mehr. Wenn ein User im Netzwerk ein Metadatenevent veröffentlicht hat, ist es für alle konsumierbar. Der Datenraum ist per se geteilt. Plattformübergreifende Suche wird durch die Kombination aus Relays und NIPs ermöglicht. In den NIPs können spezielle Query-Formate für die jeweiligen NIPs definiert werden. Relays können anzeigen, welche NIPs sie untersützten. Eine plattformübergreifende Suche ist im Nostr eine relay-übergreifende Suche.
Plattformübergreifende Kollaboration
- Obwohl nun #OEP in aller Munde sind, gibt es keine technischen Ansätze, wie (plattformübergreifende) Kollaboration technisch abgebildet werden kann
Nostr ist der technische Ansatz.
KI-Services
- KI-Services funktionieren oft nur auf der Plattform für die sie entwickelt werden
Es gibt im Nostr das Konzept der Data Vending Machines (s. auch data-vending-machines.org). Statt also einfach nur eine API zu bauen (was auch schon sehr schön ist, wenn sie offen zugänglich ist), könnten diese Services auch als Akteure im Nostr Netzwerk fungieren und Jobs annehmen und ausführen. Die Art der Jobs kann in einer Spezifikation beschrieben werden, sodass die Funktionsweise für alle interessierten Teilnehmer im Netzwerk einfach nachzuvollziehen ist.
Die Services könnten sogar monetarisiert werden, sodass sich hier auch Möglichkeiten böten, Geschäftsmodelle zu entwickeln.
Fazit
Die Open Education Community ist großartig. Es sind einzigartige und unglaublich engagierte Menschen, die sich dem hehren Ziel "Zugängliche Bildung für Alle" -> "Offene Bildung" verschrieben haben. Wir verwenden Creative Commons Lizenzen -> Commons -> Gemeingüter. Es ist okay, dass viele Projekte von Sponsoren und Förderungen abhängig sind. Was wir machen, ist im Sinne eines Gemeingutes: Öffentliche Bildung für alle. Also zahlen wir als Gemeinschaft alle dafür.
Was nicht okay ist: Dass das, wofür wir alle gezahlt haben, nach kurzer Zeit nicht mehr auffindbar ist. Dass es eingeschlossen wird. In öffentlich finanzierten Datensilos. Es muss für alle auch langfristig verfügbar sein. Sonst ist es nicht zugänglich, nicht offen. Dann ist das O in OER nur ein Label und Marketing, um für eine ABM-Maßnahme 3 Jahre Geld zu bekommen. Denn nichts anderes ist Content-Entwicklung, wenn der Content nach drei Jahren weggeschmissen wird.
Und dasselbe gilt für OEP. Offene Lernpraktiken, sind auch nur eine Phrase, wenn wir die passende technische Infrastruktur nicht mitdenken, die wirkliche Offenheit und Kollaboration und damit die Umsetzung offener Lernpraktiken ermöglicht.
Und wenn wir uns jetzt nicht Gedanken darüber machen, die Infrastruktur für offenes Lernen anzupassen, dann werden wir vermutlich in einigen Jahren sehen können, was bei politischen Umorientierungen noch davon übrig bleiben wird. Wenn die Fördertöpfe komplett gestrichen werden, was bleibt dann übrig von dem investierten Geld?
Wir brauchen Lösungen, die engagierte Communities weiter betreiben können und denen kein Kopf abgeschlagen werden kann, ohne dass wir zwei neue daneben setzen könnten.
Wir müssen uns jetzt Gedanken darüber machen.
Wie offen will öffentliche Bildungsinfrastruktur sein?

2025-06-16 14:02:24Nostr 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. 🫡

2025-06-17 11:02:38People 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.

2025-06-16 13:02:03Key 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 -

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

— 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.

2025-06-16 10:08:10Im September starten wir an der Freien Akademie für Medien & Journalismus eine Veranstaltungsreihe im Vorderen Bayerischen Wald und laden alle ein, live dabei zu sein, wenn Menschen interviewt werden, die etwas zu sagen und spannende Geschichten zu erzählen haben. Nach etwa einer Stunde werden die Kameras ausgeschaltet, sodass genug Raum bleibt für Fragen, für das Kennenlernen, für den Austausch mit Gleichgesinnten.
Die ersten Gäste ab dem 8. September: Jürgen Fliege, Joana Cotar, Gerd Reuther und Gabriele Gysi. Es gibt eine zweite Gesprächsreihe, die am 13. Oktober mit Jörg Bernig startet. Die Aufzeichnungen beginnen jeweils um 18 Uhr in einer Gaststätte im Raum Sankt Englmar. Wer eine weitere Anreise hat: Die Gegend ist wunderschön, lädt zum Entspannen ein (Wandern, hervorragende Gastronomie, Unterkünfte für jeden Geldbeutel) und verfügt über alles, was das Urlauberherz begehrt. Organistorisches und Anmeldung
8. September 2025: Jürgen Fliege – Glaube, Kirche, Hoffnung
Eine Talkshow im Ersten, präsentiert von einem Pastor, der alles mitbringt, was man braucht, um Menschen zu gewinnen: Einen besseren Werbeträger hätte sich die evangelische Kirche nicht wünschen können. Jürgen Fliege war von 1994 bis 2005 Stammgast in den Wohnzimmern und ist trotzdem oder gerade deshalb schon damals immer wieder in Konflikt geraten mit Amtsträgern aller Art. Ab 2020 hat er sich in Sachen Corona öffentlich klar positioniert und dabei auch auf die Bibel verwiesen.
9. September 2025: Joana Cotar – Acht Jahre Bundestag. Wie weiter mit der Demokratie?
Ganz stimmt das mit den acht Jahren nicht: Die zweite Legislaturperiode ist vor der Zeit zu Ende gegangen. Joana Cotar wurde zweimal über die AfD-Landesliste in Hessen in den Bundestag gewählt, war dabei 2021 auch als Spitzenkandidatin im Gespräch und zwei Jahre im Bundesvorstand. Ende 2022 hat sie Partei und Fraktion verlassen, im Parlament aber weitergemacht und immer wieder den Finger in die Wunde gelegt, wenn es um das Parteiensystem ging oder um den Spielraum der Volksvertreter.
10. September 2025: Gerd Reuther – Tatort Vergangenheit
Gerd Reuther hat sich als Medizinaufklärer ohne Tabus einen Namen gemacht – ein Radiologe, der an drei Kliniken Chefarzt war, dann aber mit 55 aufgehört hat. Sein Buch „Der betrogene Patient“ war 2017 ein Bestseller. Danach hat er die Geschichte der Medizin gegen den Strich gebürstet („Heilung Nebensache“) und in „Hauptsache Panik“ die europäische Seuchengeschichte demontiert. Jetzt nimmt er sich unsere gesamte Geschichte vor und stellt von den Römern bis in die Neuzeit unser „Wissen“ über die Vergangenheit in Frage.
11. September 2025: Gabriele Gysi – Gibt es noch eine deutsche Frage?
Niemand kann das besser beantworten als diese Künstlerin, Spross einer Politikerfamilie und Zeitzeugin für alle drei deutschen Nachkriegsstaaten – für die DDR sowieso, nach ihrer Ausreise 1984 aber auch für die alte Bundesrepublik und dann natürlich für die neue, wo sie unter anderem Chefdramaturgin der Berliner Volksbühne war. Gabriele Gysi sagt: Solange wir keine gesamtdeutsche Geschichte haben, bleibt die große Frage offen.

2024-07-28 09:16:10Jan Kolčák pochádza zo stredného Slovenska a vystupuje pod umeleckým menom Deepologic. Hudbe sa venuje už viac než 10 rokov. Začínal ako DJ, ktorý s obľubou mixoval klubovú hudbu v štýloch deep-tech a afrohouse. Stále ho ťahalo tvoriť vlastnú hudbu, a preto sa začal vzdelávať v oblasti tvorby elektronickej hudby. Nakoniec vydal svoje prvé EP s názvom "Rezonancie". Učenie je pre neho celoživotný proces, a preto sa neustále zdokonaľuje v oblasti zvuku a kompozície, aby jeho skladby boli kvalitné na posluch aj v klube.
V roku 2023 si založil vlastnú značku EarsDeep Records, kde dáva príležitosť začínajúcim producentom. Jeho značku podporujú aj etablované mená slovenskej alternatívnej elektronickej scény. Jeho prioritou je sloboda a neškatulkovanie. Ako sa hovorí v jednej klasickej deephouseovej skladbe: "We are all equal in the house of deep." So slobodou ide ruka v ruke aj láska k novým technológiám, Bitcoinu a schopnosť udržať si v digitálnom svete prehľad, odstup a anonymitu.
V súčasnosti ďalej produkuje vlastnú hudbu, venuje sa DJingu a vedie podcast, kde zverejňuje svoje mixované sety. Na Lunarpunk festivale bude hrať DJ set tvorený vlastnou produkciou, ale aj skladby, ktoré sú blízke jeho srdcu.

2025-06-17 13:07:33ในปี 1975 มหาวิทยาลัย Yale ได้ทำการศึกษาจากกลุ่มคนที่มีอายุตั้งแต่ 50 ปีจำนวน 660 คน ในหัวข้อ ความเห็นที่มีต่อ “การสูงวัยขึ้น(aging)”
กลุ่มที่หนึ่ง มีความเห็นและความเชื่อที่เป็นด้านบวก ทั้งในเรื่องสุขภาพ ความคิด ความคาดหวังที่ดี เมื่อแก่ตัวขึ้น
กลุ่มที่สอง มีความเห็นและความเชื่อที่เป็นด้านลบ ประมาณว่า “การออกกำลังกายไม่ได้ทำอะไรให้ดีขึ้นหรอก ยังไงก็ต้องป่วย ต้องตายอยู่ดี”
ปรากฎว่า เมื่อผ่านไป 23 ปี กลุ่มที่หนึ่งมีอายุขัยเฉลี่ยมากกว่ากลุ่มที่สอง ถึง 7.6 ปี ซึ่งเป็นตัวเลขที่แตกต่างกันมาก
การศึกษานี้ต้องการจะบอกอะไรกับเรา?
แน่นอนว่า ผลลัพธ์ทุกอย่าง เกิดขึ้นได้ จากการกระทำ เวลาที่เราวางแผนจะลงมือทำอะไร ล้วนแต่เริ่มต้นจาก การตั้งเป้าหมาย ทั้งสิ้น
แต่คำถามคือ เมื่อบรรลุเป้าหมายแล้ว ยังไงต่อ?
ข้อเสียอย่างหนึ่ง ของการตั้งเป้าหมายโดยมีรากฐานมาจากผลลัพธ์ที่ต้องการ คือ เรามีแนวโน้มที่จะ “หยุดทำ” เมื่อได้ผลลัพธ์ที่ต้องการแล้ว
ยกตัวอย่างเช่น การลดน้ำหนัก เราชอบมองเรื่องของการลดน้ำหนักเป็นเหมือน การจัดแคมเปญ โดยมีช่วงเวลาที่กำหนด และเมื่อบรรลุเป้าหมาย เราก็กลับมามีพฤติกรรมแบบเดิม ซึ่งทำให้น้ำหนักที่ลดลงไป กลับมา
James Clear ผู้เขียนหนังสือชื่อ Atomic Habits ได้กล่าวว่า แค่การวางแผน และลงมือทำ ไม่ได้นำมาซึ่งผลลัพธ์ที่ยั่งยืน
แต่สิ่งที่สำคัญกว่า ที่เราต้องทำคือ การกำหนดตัวตนของเราใหม่
เวลาที่เราต้องการลดน้ำหนัก 10 กิโล ให้เรามองลึกลงไปกว่าการวางแผนเรื่องการกิน และการออกกำลังกาย
แต่ให้ตั้งเป้าหมายว่า
“ต่อไปนี้ฉันจะเป็นคนที่ เลือกกินที่แต่ของที่มีประโยชน์ และจะออกกำลังกายสม่ำเสมอ” “ฉันไม่ใช่คนที่ชอบกินขนมและของที่มีน้ำตาลสูง” “ฉันเป็นนักกีฬาที่เข้มงวดต่อตารางฝึกซ้อม”
การกำหนดตัวตนของเราใหม่ เป็นเหมือนการปรับเปลี่ยน Mindset ถ้าเรา “โฟกัส” ลงไปที่แก่นของพฤติกรรมแล้ว “ผลลัพธ์” แบบที่เราต้องการจะมาเอง และยั่งยืนกว่า
การศึกษาของมหาวิทยาลัย Yale เป็นข้อพิสูจน์ของเรื่องนี้ได้อย่างดี เพราะกลุ่มคนที่มีความเชื่อที่เป็นด้านบวก จะให้ความสำคัญต่อการออกกำลังกายมากขึ้น หยุดกินเหล้า หยุดสูบบุหรี่ และใช้เวลาอยู่กับคนที่มีมุมมองเป็นบวกเหมือนกัน
เมื่อเราได้ติดสินใจแล้วว่า คนแบบไหนที่เราต้องการจะเป็น พฤติกรรมต่างๆในชีวิตประจำวันของเราจะค่อยๆ เปลี่ยนไป และจะยิ่งเห็นผลชัดเจนขึ้นเรื่อยๆในระยะยาว
เรา คือผลลัพธ์ของ สิ่งที่เราลงมือทำ
เรา คือผลลัพธ์ของ การตัดสินใจของเรา

2025-06-17 12:50:03Back in March of this year, my friend nostr:nprofile1qyfhwumn8ghj7ctvvahjuat50phjummwv5q35amnwvaz7tmrv968xarjwgh8xampwfkhxarj9e3k7mgqyrcmjyd0r3a9vpe78wpm5l42dq2xwpqwp7aa6fj5gk4gpejuyaxzy06fp23 - a photographer I met on Nostr in the Bitcoin community, though I think he was initially acquainted with me through my photography publication, nostr:nprofile1qyvhwumn8ghj7etvd96x2uewdehhxarjv96xjtn0wfnszrthwden5te0dehhxtnvdakqqgrr6kwm3556hc5akuuqh6u39w8kqq3hxv4kextckgyxjnjtu9c0dutqvkwz — reached out asking if I wanted to be his production assistant for a shoot with David Byrne for his new album, “Who is the Sky?”.
Ahmed and David.
I wasn't too familiar with David before Ahmed asked, but I knew him from the Talking Heads, so obviously I said yes. Then came the logistics of actually making it happen - scheduling everything around and figuring out if I could pull off the trip from South Carolina all the way up to Manhattan.
The Journey North
The drive involved coordinating between Airbnbs and making strategic stops along the way. I stayed at my dad's house for a few days in Charlotte, which I tend to do whenever I travel north. It's always a good stop to see my dad since I don't get to see him very often. From there, I scheduled a couple Airbnbs in Jersey City, where I was able to see my friend Raf - always nice to catch up with him and drop off some rolls of film (watch our interview together here).** **The next day I got another Airbnb in a different city, then drove the following morning to a parking garage in Manhattan that was a block or two from Ahmed's studio.
Sunday Afternoon Studios
The studio is called Sunday Afternoon Studios, and of course I was the first one there - I'm always early to things. I find it better to be early than late, and it's never a problem for me because I usually just end up walking around, taking pictures, and being able to relax without worrying about rushing to get somewhere.
When I told my dad about how this shoot was going to happen, he said, "Make sure to get a picture of him on his bike" - apparently David rides his bike around the city quite often. I kept that in mind, and when David came in, sure enough, he came up the elevator with his bike. I thought of my dad and took a quick picture and sent it to him. He appreciated that, so that was cool.
Davids bike.
The Shoot
The shoot took a few hours, starting at 10 AM and wrapping up around 4:30 PM with cleanup. It was a gread day - I had a lot of fun and was able to learn more on lighting methods and setting up things I'd never worked with before in a professional environment. But I was also doing some documentary work with my Leica M262, so that's what these photos were taken with.
David's outfit, by the way, was extremely heavy - must've been at least 50 pounds or something like that. When I had to put it back in the box to ship it back to wherever it came from, I really noticed how heavy this thing actually was. It was made out of plastic tubing and zip ties and bungee cords and stuff. Actually really cool design work.
Ahmed and his newborn, Harmony.
I had a great time. Big thanks to Ahmed and crew for this opportunity to help out, meet David, and take some pictures. Really great experience. I feel very grateful for everything.
Thanks for reading.

2025-06-17 06:01:51Contribute to keep No Bullshit Bitcoin news going.
- 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.
Destroy Seed
also removes all Trick PINs from SE2.Lock Down Seed
requires pressing confirm key (4) to execute.- Q only: Only BBQr is allowed to export Coldcard, Core, and pretty descriptor.

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

So much for that tariff hyperinflation.\ \ New inflation numbers came at 1.2% — way below the Fed’s target.\ \ For the 4th time in Trump’s 4 months.\ \ Yet not a word about easing from the fed. Who’s now moving the inflation goal-posts to 2026 or even 2027. pic.twitter.com/nwzSCABrbR
— Peter St Onge, Ph.D. (@profstonge) June 16, 2025
After months of pundits, politicians, and partisan hacks kvetching about the aggressive tariff regime put forth by the Trump administration, we're beginning to see some data tickle in that makes it seem as if the tariff strategy may actually be working. At the end of last week, inflation data hit the market cooler than expected. Some core components coming in below the Federal Reserve's 2% inflation target. Granted, the CPI is manipulated and may be underreporting actual inflation. However, if we're simply comparing the CPI to itself, it seems to be moving in the right direction if, like me, you don't like when prices consistently rise month on month, year on year, decade on decade.
On top of this, the amount of revenue that tariffs are bringing in is significant and rising quickly. In May, tariff revenue collected in the U.S. hit a record of $22.3 billion. In April, the U.S. government brought in $16.5 billion from tariffs, and collectively, since Trump took office, the government has brought in around $67.2 billion in tariff revenue. Tariffs now reflect 4% of the total federal revenue, which is up from an average of 2% over the last few years. If this trend keeps up, the idea that tariffs can replace income tax revenue in the United States seems to be validated. Even better, it seems that the increased inflation that many were warning about hasn't materialized yet. There could be a way to increase the revenue of the federal government without increasing taxes on American producers while keeping prices lower. This is a beautiful thing.
I don't think it's time to ring the bell and claim victory in regards to tariffs and inflation quite yet, but this is extremely encouraging and something that all of you should be monitoring closely in the months ahead. Whether you're a Republican or a Democrat, I think we should all celebrate if the bold strategy of levying tariffs on the rest of the world to bring manufacturing home, while the government produces revenue via means that don't attack the income of individual citizens actually works out in the end.
It's crazy what pricing your life in Bitcoin does as you surf the internet. This newsletter was partly inspired by the video above from our good friend Peter St. Onge, but also because of this tweet I saw earlier today that priced the tariff revenue in bitcoin.
The Kobeissi Letter did not include the bitcoin denominations in its tweet. Our browser extension, Opportunity Cost, automatically injected it into the tweet so that I could understand how much revenue the government is bringing in in terms of Bitcoin. If they chose to use Bitcoin as a reserve asset.
It's crazy to think that at current bitcoin prices and if tariff revenue stays at the level it reached last month, the United States government could acquire a strategic reserve of 1 million bitcoin in less than five months. That really puts things into perspective, for me at least, about how much money is being thrown around the system both in the private markets and the public sector.
We are still extremely early in terms of bitcoin's adoption and monetization. Just looking at the tweet makes me want to tap somebody on the shoulder in the government and say, "Hey, look at this. If you sacrifice less than five months of tariff revenue and funnel that into bitcoin, you could have your strategic reserve by the end of the year. Before Thanksgiving even."
If tariff revenue continues to increase at the pace it has over the last couple of months, and the economy recovers, inflation isn't that bad, why not? Why not start building the strategic reserve with some of these revenues? A man can dream.
Washington's Bitcoin Awakening: From Crime Concerns to Strategic Asset
Ken Egan described a remarkable shift in how Washington views Bitcoin. Just a year ago, he recalls fighting defensive battles against basic misconceptions about criminal use and technical vulnerabilities. Today, policymakers ask sophisticated questions about Bitcoin's role in global monetary competition and national security strategy. Egan emphasized that discussions no longer waste time on "is it just for buying drugs" but instead focus on how Bitcoin can counter China's parallel financial systems and strengthen America's competitive position.
"There are people thinking, even the Department of Energy, some of whom will be at our conference, thinking really deeply about everything this ecosystem has to offer and how we can apply it to sort of a comprehensive national security strategy." - Ken Egan
Multiple government departments are now actively exploring Bitcoin's potential, Egan revealed. The Department of Defense examines mining for energy resilience, while the Department of Energy considers grid applications. Trump's executive order formally distinguished Bitcoin from other cryptocurrencies, signaling institutional recognition of its unique properties. This evolution from skepticism to strategic thinking represents a fundamental transformation in how America's policy establishment approaches Bitcoin.

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

2025-06-17 12:02:26Lightspark introduces a layer 2 for instant payments, stablecoins and interoperability with Lightning.
Spark is an open-source layer 2 protocol developed by Lightspark, designed to offer instant low-cost payments without the need for intermediaries. It allows the creation of wallets and applications that interact directly with the Bitcoin and Lightning networks. The company’s stated goal is to transform Bitcoin into a true global digital currency, solving the scalability limitations of the base layer.
Lightspark, a company led by David Marcus (former PayPal and former Facebook), officially launched Spark in beta version on April 29, 2025. Developers can already use Spark’s SDKs (Wallet and Issuer) to build self-custodial wallets compatible with Lightning and tokens (such as stablecoins) native to the Bitcoin network.
How it works
Spark adopts a statechain-based approach, allowing the transfer of ownership of a UTXO off-chain between different users without using the main blockchain, thus reducing costs and transaction times. Instead of executing an on-chain transaction that physically moves the asset, users acquire signing rights or control over a key that represents a bitcoin UTXO. Transfers occur through a chain of signatures and a mechanism that allows subsequent transactions to overwrite previous ones, ensuring that neither the user nor the service provider (Spark Service Provider, SSP) can lose funds during the operation.
Spark is designed to be fully interoperable with LN, supporting not only bitcoin transactions, but also stablecoins and other tokenized assets. SSPs facilitate Lightning payments by accepting funds on Spark and converting them into Lightning transactions or vice versa, eliminating the need for users to manage nodes or worry about channel liquidity. For example, a user can pay an LN invoice with a stablecoin on Spark, with the SSP converting the stablecoin to BTC in the background and sending the funds to the recipient.
Shared signature model (multisig 2-of-2)
Unlike the LN trust model, which is based on peer-to-peer bidirectional channels with smart contract logic, Spark involves a coordinating entity, the “Spark Service Provider” (SSP). This shifts part of the risk from channel liquidity management to trust in operators who sign off-chain transactions. The SSP’s task is to sign “blindly” (blindly) on behalf of the user, which means the SSP does not see the content of the signature and does not even know if it is signing a Bitcoin transaction or something else.
Bitcoin deposited on Spark always remains under the user’s control. When a user sends funds to Spark, they are initially transferred to a statechain. Once funds are on the statechain, payments on the Spark network occur instantly and at near-zero costs.
At the heart of Spark’s security is the use of a shared signature scheme, specifically a multisig 2-of-2 model. This means that two keys are required to authorize a transaction, and the user always holds one. When users deposit funds on Spark, they send them to a multisig address. Here, they maintain control of their funds and can perform a unilateral exit without the need to interact with other parties.
Each payment is enabled by a Spark Service Provider (SSP), which must co-authorize the transaction together with the user for it to be valid and successful.
Although the network is currently managed only by Lightspark and another operator (Flashnet), users do not risk losing funds even if these operators stopped cooperating. In fact, Spark offers the possibility to unilaterally force the return of bitcoin to the mainnet at any time. Users can exit Spark in two ways: through a cooperative exit (cheaper and faster) or a unilateral exit (slower, but possible in case of malfunction or loss of trust). Lightspark has declared its intention to add more operators in the future to increase decentralization.
Fee structure
Regarding fees, transactions within the Spark network are zero fee. The only fees users will have to bear are Bitcoin’s on-chain fees for depositing or withdrawing funds from Spark. Additionally, transferring bitcoin from Spark to LN involves a 0.25% fee plus routing fees. Conversely, a transaction from LN to Spark costs 0.15%.
The native LRC20 token protocol
Introduced in the summer of 2024, LRC20 is a token issuance protocol designed to be compatible with both Bitcoin’s mainnet and LN. Anyone can issue an LRC20 token. The protocol also supports freeze and burn operations, giving the original issuing wallet the power to freeze tokens at any address, preventing transactions until unlocked. LRC20 is primarily designed for issuing stablecoins and regulated assets.
After thoroughly testing it, the Lightspark team decided to run the LRC20 protocol natively on Spark, to enable token issuance on the network.
Ecosystem and partnerships
The birth of Spark has immediately attracted the interest of other Bitcoin projects. Among the various partnerships established, the multisig wallet Theya has integrated Spark to offer its users simpler and faster bitcoin and stablecoin payments.
Last May, Breez announced a new implementation of the Breez SDK based on Spark, which allows developers to integrate Lightning payments directly into their apps through Spark. As part of this collaboration, Breez will also act as a Spark Service Provider, helping to expand the ecosystem. According to the two companies, this partnership will provide developers with new Bitcoin-native tools for use cases such as streaming payments, international remittances and micro-payments for AI.
The post Spark: the layer 2 launched by Lightspark appeared first on Atlas21.

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

2025-06-16 18:02:23The 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.

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.

2025-06-15 11:51:30Know 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.
Edited 20/03/2024 * Add reference to the 1% statement on Rights for Illusions section to an article where Chainalysis found that only 0.34% of the transaction volume with cryptocurrencies in 2023 was attributable to criminal activity ^1

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

2025-06-16 18:02:23What 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.

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

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

"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.

2025-06-16 18:02:22The 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

2025-06-15 03:31:00How do you look at the things in your life?
-
Do you focus on your physical problems or do you look forward to your resurrection body in heaven?
-
Do you spend your time trying to fix the corruption in government or do you spend your time trying to bring as many people as possible home to heaven?
-
When you see someone suffering do you first pray for their physical healing or do you pray for their spiritual healing?
-
Do you work to fit in with the people around you or do you work to become more Christ-like?
-
Do you crave entertainment or do you crave biblical enrichment?
-
Do you focus more on your citizenship here on earth or more on your eternal citizenship?
-
Do you seek fellowship with the people of this world or do you seek fellowship with your Savior?
-
Do you look at people’s faults and how they hurt you or do you look at their hurt and separation from God and seek to bring them to Jesus?
-
Do you spend your time on work and entertainment or do you spend your time studying the word of God, praying to God, and telling others about God?
Do you have an earthly or an eternal perspective?
Physical or Spiritual Needs
Jesus always had an eternal perspective. This event is just one example.
One day He was teaching; and there were some Pharisees and teachers of the law sitting there, who had come from every village of Galilee and Judea and from Jerusalem; and the power of the Lord was present for Him to perform healing. And some men were carrying on a bed a man who was paralyzed; and they were trying to bring him in and to set him down in front of Him. But not finding any way to bring him in because of the crowd, they went up on the roof and let him down through the tiles with his stretcher, into the middle of the crowd, in front of Jesus. Seeing their faith, He said, “Friend, your sins are forgiven you.” The scribes and the Pharisees began to reason, saying, “Who is this man who speaks blasphemies? Who can forgive sins, but God alone?” But Jesus, aware of their reasonings, answered and said to them, “Why are you reasoning in your hearts? Which is easier, to say, ‘Your sins have been forgiven you,’ or to say, ‘Get up and walk’? But, so that you may know that the Son of Man has authority on earth to forgive sins,”—He said to the paralytic—“I say to you, get up, and pick up your stretcher and go home.” (Luke 5:17-24) {emphasis mine}
In this familiar story a man who was paralyzed was brought to Jesus for healing. The paralytic’s friends worked so hard to get him physically healed that they hauled him up on the roof, dug through the roof, and lowered him down in front of Jesus. What was Jesus’s response? Jesus forgave the man’s sins. Every person there saw the man’s need to be able to walk, so he could take care of himself here on earth. Jesus saw the more important spiritual need and forgave his sins. After taking care of his eternal need, he also took care of his more earthly need and healed him physically.
Do you see people’s eternal need or do you just see their physical needs or worse, only see their earthly failings? Do you only see the hurt they are causing you or do you see the hurt they feel that comes from being separated from God?
Earthly or Heavenly Citizenship
I’ve been involved in politics for many years. I’ve been to precinct, county, state, and national conventions. I’ve written, debated, and defended political platforms and resolutions. I vote every election. All of that is good and useful, but is that where we are supposed to spend most of our time and effort? I’ve come to the conclusion that this is not what is most important.
For our citizenship is in heaven, from which also we eagerly wait for a Savior, the Lord Jesus Christ; who will transform the body of our humble state into conformity with the body of His glory, by the exertion of the power that He has even to subject all things to Himself. (Philippians 3:20-21)
We are told that our citizenship is in heaven. The majority of our effort should be put into support of our heavenly citizenship, not our earthly citizenship. That doesn’t mean that we should let our earthly kingdom fall apart and turn away from God, but it does mean we should be more focused on turning hearts and minds to Jesus than we are with setting domestic laws. We should be more focused on worshipping God than supporting politicians.
Sadly I see too many Christians who focus on pushing the “Pledge of Allegiance to the Flag” than they do pushing loyalty to Jesus. I see too many Christians who put all of their effort into electing the “right” politician instead of pointing people to the real Savior. I see too many Christians who try to pass the “right” laws instead of reading the law of God. I see too many Christians who put all of their effort into changing people’s minds to the “right” party instead of changing hearts and minds for Christ.
Do you really seek the kingdom of God or are you only focused on your earthly nation? Do you spend more time trying to win people for your political party than you do trying to win people for Christ? Our primary focus should be on the Millennial Kingdom of Christ and on eternity in heaven with Jesus, not on our earthly country.
Yes, we are to be a light in the world and we should seek the good of our earthly nations, but sharing the gospel, living a life honoring to God, and doing everything within our power to draw people to Jesus should be our focus and where we put most of our effort.
And He came and preached peace to you who were far away, and peace to those who were near; for through Him we both have our access in one Spirit to the Father. So then you are no longer strangers and aliens, but you are fellow citizens with the saints, and are of God’s household, having been built on the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone, in whom the whole building, being fitted together, is growing into a holy temple in the Lord, in whom you also are being built together into a dwelling of God in the Spirit. (Ephesians 2:17-22)
The Hurt They Cause or the Hurt They Feel
People today are selfish and hurtful. Most people are trying to be the greatest victim which means they are accusing others of being abusers, tyrants, or haters. People are impolite, inconsiderate, and sometimes downright hateful. How do you respond?
Do you attack back when you are attacked? Are you rude back when you are treated rudely? Do you only see how others hurt you or can you see the hurt behind the hurtful behavior?
Most of the people who are striking out with hate and anger are truly hurting people. They have been taught that they are evolved pond scum and feel hopeless. They have been mistreated by other hurting people. They have been taught to be victims and to hate anyone who may not be a victim. Instead of feeling hate, we should feel compassion.
In Matthew 18:21-35 Jesus tells a parable of a master who forgives his slave of his debts, but then that slave does not show the same mercy to another who owes him much less. The slave is rebuked.
Then summoning him, his lord said to him, ‘You wicked slave, I forgave you all that debt because you pleaded with me. Should you not also have had mercy on your fellow slave, in the same way that I had mercy on you?’ (Matthew 18:32-33)
God loved us before we loved Him. Jesus forgave us far more than we can ever forgive others. After all Jesus did for us, we should be forgiving like He is. We should see other’s hurt and eternal destination and have compassion on them. Instead of treating them the way we were treated, we should treat them like Jesus treated us. We should seek their eternal good above our momentary comfort.
And He said to them, “Come away by yourselves to a secluded place and rest a while.” (For there were many people coming and going, and they did not even have time to eat.) They went away in the boat to a secluded place by themselves.
The people saw them going, and many recognized them and ran there together on foot from all the cities, and got there ahead of them. When Jesus went ashore, He saw a large crowd, and He felt compassion for them because they were like sheep without a shepherd; and He began to teach them many things. (Mark 6:31-34) {emphasis mine}
Just as Jesus had compassion for the crowd and their spiritual needs when He and His disciples had need of food and rest, in the same way we should sacrifice our egos to minister to the spiritual needs of those that may seem unlovable because of their eternal need.
May the Lord of Heaven help us to have an eternal perspective and to view everything and everyone with that eternal and spiritual perspective so we can faithfully serve Jesus and bring with us a plentiful harvest. May Jesus use us for His glory and for the eternal good of those around us.

2024-07-25 20:53:07AI hype vnímame asi všetci okolo nás — už takmer každá appka ponúka nejakú “AI fíčuru”, AI startupy raisujú stovky miliónov a Európa ako obvykle pracuje na regulovaní a našej ochrane pred nebezpečím umelej inteligencie. Pomaly sa ale ukazuje “ovocie” spojenia umelej inteligencie a človeka, kedy mnohí ľudia reportujú signifikantné zvýšenie produktivity v práci ako aj kreatívnych aktivitách (aj napriek tomu, že mnohí hardcore kreatívci by každého pri spomenutí skratky “AI” najradšej upálili). V prvej polovici prednášky sa pozrieme na to, akými rôznymi spôsobmi nám vie byť AI nápomocná, či už v práci alebo osobnom živote.
Umelé neuróny nám už vyskakujú pomaly aj z ovsených vločiek, no to ako sa k nám dostávajú sa veľmi líši. Hlavne v tom, či ich poskytujú firmy v zatvorených alebo open-source modeloch. V druhej polovici prednášky sa pozrieme na boom okolo otvorených AI modelov a ako ich vieme využiť.

2025-06-16 18:02:20Nostr 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. 🫡

2025-06-17 10:09:10In today’s financial landscape there are many markets to choose from two of which are forex (foreign exchange) and cryptocurrency. Forex is a far more established market. Additionally most forex activity is done by experienced traders whereas crypto is a mix of institutional and bulk investors. In the case that people use forex it is often in a mid-sized transactions for activities such as travel.
What is forex trading?✔ Forex trading is a process where one currency is exchanged for another. With daily trading volumes over $6 trillion it’s the largest financial market globally. Forex operates 24 hours a day five days a week and traders can speculate on the relative value of currency pairs.
There are several important aspects of forex trading.
What is crypto trading? Crypto trading involves selling and buying digital currencies as long as they rely upon blockchain technology. Commercial banks central banks and investment firms are considered the most powerful financial institutions in terms of influencing the friction of a market or the flow of currency transactions in the crypto market. Cryptocurrencies are distinct from traditional currency because they are stateless and don’t have a central administrator. Some well-known coins include Bitcoin (digital gold) and Ethereum (having smart contract capabilities). Stablecoins are the most common form of crypto for settlement and liquidity between exchanges and traders. The most common are fiat currency denominated stablecoins of which USDT and USDC are the most popular and are dollar-denominated.

2025-06-17 09:42:58CHAPTER FORTY
James scoffed quietly, his jaw tightening. "He gave up the right to judge me the day he cast me out. Everything I have now, I earned without his shadow."
He walked toward the bar, poured himself a glass of water, and turned back to Rosa.
"Why are you telling me this now?"
She swallowed, her voice lowering. "Because I don’t want to be on the losing side when the truth comes out. And because I believe in you. Despite everything, you did what none of them could revive a crumbling empire. That has to count for something."
James studied her for a moment, then nodded. "It does. More than you know."
The following day dawned, cloaked in a deceptive stillness. The city, oblivious to the brewing storm within the corridors of power, bustled with its usual rhythm. But within the executive tower of JP Enterprises, the atmosphere was anything but ordinary.
James sat in his office, the vast room silent except for the soft hum of the air conditioning. The files laid out before him were damning evidence of not only his father’s covert betrayal, but also a trail of influence that reached far beyond what he had initially imagined. There were names, transfers, off-the-record meetings, and veiled communications each pointing to a calculated attempt to usurp his leadership under the guise of concern for the company’s future.
His eyes narrowed as he read through the final report. The extent of the deception wasn’t just hurtful but also enraging. These weren’t mere business rivalries; they were orchestrated acts of sabotage, engineered by those who once claimed to be family.
Just then, his assistant, Cole, stepped in.
“Sir, the board has gathered. They're waiting for you in the main conference hall,” he said respectfully.
James stood, adjusted his tailored suit, and nodded. “Let’s not keep them waiting.”
As he walked through the corridor, whispers followed him. The viral scandal, though rapidly discredited thanks to Rosa’s intervention, had left behind its sting. But James moved with the composure of a man who had endured fire and emerged unburnt.
Inside the boardroom, every seat was occupied. Helen and Mark were present, feigning innocence, while other executives exchanged nervous glances. Even Mr. JP had arrived early, seated at the far end, his expression inscrutable.
James entered and placed a thick folder on the table with deliberate calm.
“Ladies and gentlemen,” he began, his voice composed yet firm, “the recent rumors surrounding my integrity and leadership have not only been malicious but entirely fabricated. Today, I present to you the evidence of the orchestration behind those lies.”
He opened the file, revealing photographs, digital footprints, financial trails, and a list of corroborated testimonies. Gasps echoed softly as names began to surface Mark, Helen, and to the surprise of many, Mr. JP himself.
James didn’t flinch as the tension escalated.
“This company stands on the foundation of transparency, innovation, and integrity,” he continued. “If we allow treachery to flourish within our ranks, we compromise everything we claim to be.”
A heavy silence followed.
Mr. JP slowly stood, his voice low but resonant. “Is this your retribution, James? Exposing your own blood before the board?”
James met his gaze without wavering. “This is accountability, father. You taught me to protect the legacy, not the lies.”
The room held its collective breath.
After a moment of silence, a senior board member cleared his throat. “We move to vote on the proposed expulsion of those found guilty of misconduct,” he said, and one by one, the members raised their hands.
As Helen’s face drained of color and Mark muttered a curse under his breath, James stood motionless. Not out of pride but out of quiet triumph. For once, truth had prevailed not through vengeance, but by the sheer strength of character.
James, once scorned and ridiculed by those who couldn’t see beyond his humble beginning, had not only reclaimed his name but restored honor to the JP legacy. The revelation of his identity silenced critics and vindicated every hardship he endured. No longer just the mysterious President of JP Enterprises, he stood proud as the rightful heir, an important leader shaped by fire, not privilege.
Hi again. She and James, once distant due to family interference, reconnected this time with mutual respect and quiet understanding.
Mr. and Mrs. JP had returned not only to witness the revival of their empire but to make peace with their only son. With tearful eyes, they welcomed James back not just as a son but as a man who had become greater than they had ever imagined.
James, ever composed, continued to lead with excellence and grace. He never let power cloud his judgment or pride dictate his path. He remembered where he came from and used that pain as a compass.
And so, the man who was once dismissed as a beggar walked boldly into his destiny not to seek revenge, but to rewrite the narrative. His story became one whispered in corporate circles and told in classrooms a testimony that no matter how dark the beginning, greatness can still emerge from the shadows.

A quick and easy recipe to help preserve your fresh strawberry harvest for months to come with the addition of vanilla to bring out that summer flavour.
Made with 20% extra fruit than standard supermarket jam. To make a reduced sugar version you can use Pomona's Pectin or accept runny jam ;)
Details
- ⏲️ Prep time: 10 mins
- 🍳 Cook time: 30 mins
- 🍽️ Servings: 5 jars
Ingredients
- 1.2kg fresh hulled strawberries
- 1kg golden cane sugar (can sub honey or maple syrup 1:1)
- 1 lemon
- 1 vanilla pod (or 1 tbspn extract)
Directions
- Remove the green stalks from your strawberries and cut into quarters
- Pare the lemon zest and reserve for another recipe (such as lemon curd, or cocktails!), chop roughly and add to a pan inside a small muslin bag)
- Gently cook the strawberries and lemon together with a lid on the pan for 15-20 minutes, until the lemon pith softens
- Squeeze the muslin bag to get as much pectin out as possiblem then add 1kg sugar to the miture and boil on high
- The jam can be tested for set after approx 10 mins boiling, spoon a small amount onto a chilled plate and place in the freezer for 2 minutes. If the jam wrinkles when pushed with a spoon it is ready to pot into sterlised jars. If it still appears runny cook for a further 5 minutes and repeat testing
