2025-05-12 14:50:36A posição do libertário que rejeita o cristianismo padece de sérias incoerências lógicas, históricas e filosóficas. Ao renegar as bases espirituais e culturais que tornaram possível o próprio ideal libertário, tal posição demonstra ser, ao mesmo tempo, autofágica e irracional. É o caso de alguém que se gloria dos frutos de uma árvore que corta pela raiz.
I. Fundamento histórico: a civilização da liberdade é cristã
Não foi o secularismo moderno, nem o paganismo antigo, que ergueram as instituições que protegem a dignidade da pessoa humana e os limites ao poder. Desde os primeiros séculos, a Igreja resistiu ao culto estatal romano, afirmando a soberania de Deus sobre os Césares — "Mais importa obedecer a Deus que aos homens" (Atos 5,29).
Foi o cristianismo que:
-
Fundou universidades livres, onde o saber era buscado sob o primado da verdade;
-
Defendeu a lei natural como fundamento do direito — uma doutrina que protege o indivíduo contra tiranias;
-
Resgatou e aprofundou o conceito de pessoa, dotada de razão e livre-arbítrio, imagem de Deus, e, portanto, inalienavelmente digna e responsável.
Em momentos-chave da história, como nas disputas entre papado e império, nas resistências contra absolutismos, e na fundação do direito internacional por Francisco de Vitoria e a Escola de Salamanca, foi o cristianismo quem freou o poder estatal em nome de princípios superiores. A tradição cristã foi frequentemente o principal obstáculo à tirania, não seu aliado.
Negar isso é amputar a própria genealogia da liberdade ocidental.
Uma das chaves do cristianismo para a construção dessa civilização da liberdade foi a exaltação do individualismo. Ao afirmar que o ser humano é feito à imagem de Deus e que sua salvação é uma escolha pessoal, o cristianismo colocou o indivíduo no centro da moralidade e da liberdade. Diferente dos gregos, cuja ética era voltada para a polis e a cidade-estado, o cristianismo reafirma a suprema importância do indivíduo, com sua capacidade de escolha moral, responsabilidade pessoal e dignidade intrínseca. Esse princípio, mais do que qualquer outra religião, foi o alicerce do desenvolvimento da liberdade individual e da autonomia, valores que sustentam a civilização ocidental.
A ética grega, na melhor das hipóteses, descreve a ordem natural — mas não consegue justificar por que essa ordem deveria obrigar a vontade humana. Um Logos impessoal não tem autoridade moral. Uma ordem cósmica sem um Legislador é apenas um dado de fato, não uma norma vinculante. A vontade pode rebelar-se contra o telos — e sem um Deus justo, que ordena a natureza à perfeição, não há razão última para não o fazer.
A cultura grega teve uma influência indiscutível sobre o desenvolvimento da civilização ocidental, mas o cristianismo não só absorveu o que havia de bom na cultura grega, como também elevou e completou esses aspectos. O cristianismo, ao afirmar que todos os homens são feitos à imagem e semelhança de Deus e têm dignidade intrínseca, levou a uma noção de igualdade moral e liberdade que transcende as limitações da pólis grega.
II. Falsa dicotomia: fé e liberdade não são opostas
Com frequência equiparam a religião à coerção e à obediência cega. Mas isso é um equívoco: o cristianismo não se impõe pela força, mas apela à consciência. O próprio Deus, em sua relação com a criatura racional, respeita sua liberdade. Como ensina a Escritura:
"Se alguém quiser vir após mim..." (Mt 16,24);
"Eis que estou à porta e bato. Se alguém ouvir a minha voz e abrir a porta, entrarei em sua casa e cearei com ele." (Ap 3,20);
"Assim falai, e assim procedei, como devendo ser julgados pela lei da liberdade." (Tiago 2,12).A adesão à fé deve ser livre, voluntária e racional, pois sem liberdade não há verdadeiro mérito, nem amor genuíno. Isso é mais compatível com o princípio de não agressão do que qualquer utopia secular. Ora, o núcleo do evangelho é voluntarista: salvação pessoal, conversão interior, caridade.
Ninguém deve ser forçado, contra sua vontade, a abraçar a fé, pois o ato de fé é por sua natureza voluntário (Dignitatis Humanae; CDC, cân. 748,2)
Se algum Estado usa da força para impor o cristianismo, afirmar que o cristianismo causou as coerções é tão equivocado quanto dizer que a propriedade privada causa o comunismo; é uma inversão da realidade, pois o comunismo surge precisamente da violação da propriedade. Portanto, a fé forçada é inválida em si mesma, pois viola a natureza do ato de crer, que deve ser livre.
III. Fundamento moral: sem transcendência, o libertarianismo flutua no vácuo
O libertário anticristão busca defender princípios objetivos — como a inviolabilidade do indivíduo e a ilegitimidade da agressão — sem um fundamento transcendente que lhes dê validade universal. Por que a agressão é errada? Por que alguém tem direito à vida, à liberdade, à propriedade? Sem uma explicação transcendental, as respostas para tais perguntas se tornam apenas opiniões ou convenções, não obrigações morais vinculantes. Se a moralidade é puramente humana, então os direitos podem ser modificados ou ignorados conforme a vontade da sociedade. O conceito de direitos naturais, tão caro ao libertarianismo, precisa de um solo metafísico que justifique sua universalidade e imutabilidade. Caso contrário, eles podem ser tratados apenas como acordos utilitários temporários ou preferências culturais, sem qualquer obrigatoriedade para todos os seres humanos em todas as circunstâncias.
Pensadores libertários seculares, como Ayn Rand e Murray Rothbard, tentaram ancorar os direitos naturais na razão humana ou na natureza do homem. Rand baseia sua ética no egoísmo racional, enquanto Rothbard apela à lei natural. Embora essas abordagens busquem objetividade, elas carecem de uma resposta definitiva para por que a razão ou a natureza humana obrigam moralmente todos os indivíduos. Sem um fundamento transcendente, suas concepções permanecem vulneráveis a interpretações subjetivas ou a cálculos utilitários.
Aqui, o cristianismo oferece uma explicação sólida e transcendental que fundamenta os direitos naturais. A visão cristã de que o ser humano foi criado à imagem e semelhança de Deus confere à pessoa uma dignidade intrínseca, imutável e universal. Essa dignidade não depende de fatores externos, como consenso social ou poder político, mas é uma característica inerente ao ser humano pela sua criação divina. A partir dessa perspectiva teológica, torna-se possível afirmar com base sólida que os direitos naturais são dados por Deus e, portanto, são universais e vinculantes.
O cristianismo também é a base de um sistema moral que distingue claramente justiça de legalidade. O Estado pode criar leis, mas isso não significa que essas leis sejam justas. A justiça, sob a ótica cristã, é uma expressão da ordem moral objetiva, algo que transcende as leis humanas e é definido pela vontade divina. Por isso, o libertarianismo cristão vê a agressão como uma violação de uma ordem moral objetiva, e não apenas uma violação de uma convenção social ou de um acordo utilitário.
Se a moralidade e os direitos naturais não forem fundamentados em um Logos criador e legislador, o que acontece é que o conceito de direito natural degenera para algo mais frágil, como um simples acordo utilitário. Nesse cenário, os direitos do indivíduo se tornam algo acordado entre os membros de uma sociedade, em vez de princípios imutáveis e universais. Os direitos podem ser negociados, alterados ou ignorados conforme o interesse do momento.
IV. Fundamento científico: a racionalidade moderna é filha da fé cristã
A ciência moderna só foi possível no contexto cultural cristão. Nenhuma outra civilização — nem a grega, nem a islâmica, nem a chinesa — produziu o método científico como o Ocidente cristão o fez.
Isso se deve a quatro premissas teológicas:
-
Criação racional: O mundo é ordenado por um Deus racional.
-
Distinção entre Criador e criatura: A natureza não é divina e pode ser estudada sem sacrilégio.
-
Valor do trabalho e da observação empírica, herdado do monaquismo.
-
Autonomia institucional, presente nas universidades medievais.
A doutrina cristã da Criação ex nihilo ensina que o mundo foi criado por um Deus racional, sábio e pessoal. Portanto, o cosmos é ordenado, possui leis, e pode ser compreendido pela razão humana — que é imagem do Criador. Isso contrasta fortemente com as cosmovisões panteístas ou mitológicas, onde o mundo é cíclico, arbitrário ou habitado por forças caprichosas.
Sem essa fé no Logos criador, não há razão para crer que a natureza tenha uma ordem inteligível universal e constante, que pode ser descoberta por observação e dedução. A ciência moderna só é possível porque, antes de investigar a natureza, pressupôs-se que ela era investigável — e isso foi uma herança direta do pensamento cristão.
Homens como Bacon, Newton, Kepler e Galileu viam na ciência um modo de glorificar o Criador. O ateísmo cientificista é, portanto, parasitário da teologia cristã, pois toma seus frutos e rejeita suas raízes. A ciência moderna nasceu como filha legítima da fé cristã. E os que hoje a usam contra sua mãe, ou são ingratos, ou ignorantes.
V. O cristianismo como barreira à revolução cultural
O cristianismo é a barreira mais sólida contra a infiltração revolucionária. A chamada "marcha gramsciana", que visa corroer os fundamentos morais da sociedade para subjugar o indivíduo ao coletivo, encontra sua resistência mais firme nos princípios cristãos. A fé cristã, ao proclamar a existência de uma verdade objetiva, de uma lei moral imutável e de uma dignidade humana que transcende o Estado e o consenso social, imuniza a civilização contra o relativismo e o igualitarismo nivelador do marxismo cultural.
Além disso, o cristianismo é uma tradição milenar, profundamente enraizada no cotidiano das pessoas, não sendo uma novidade a ser imposta ou implementada, mas uma força presente há séculos, que permeia a estrutura social, moral e cultural da sociedade. Sua presença constante nas comunidades, desde os tempos mais antigos, oferece uma resistência robusta contra qualquer tentativa de subverter a ordem natural e moral estabelecida.
Não por acaso, tanto Karl Marx quanto Antonio Gramsci identificaram no cristianismo o principal obstáculo à realização de seus projetos revolucionários. Marx chamou a religião de "ópio do povo" porque sabia que uma alma ancorada em Deus não se submete facilmente ao poder terreno; Gramsci, mais sutil, propôs a destruição da cultura cristã como pré-condição para o triunfo do socialismo. Sem essa âncora transcendente, a sociedade torna-se presa fácil das engenharias sociais que pretendem redefinir arbitrariamente o homem, a família e a liberdade.
Conclusão
O libertário anticristão, consciente ou não, nega as fundações mesmas do edifício que habita. Ao rejeitar o cristianismo, cava o abismo sob os próprios pés, privando o ideal libertário de sua base moral, cultural e racional. Ele defende a ética voluntária, a liberdade individual e a ordem espontânea, mas sem o solo metafísico e histórico que torna esses princípios inteligíveis e possíveis. É um erro tentar preservar a liberdade em termos absolutos sem reconhecer as raízes cristãs que a sustentam, pois o cristianismo é a única tradição que a legitima e a viabiliza.
Negar o cristianismo é racionalmente insustentável. A liberdade, como a conhecemos, é filha da fé cristã, que oferece a base moral e metafísica que torna a liberdade tanto desejável quanto possível. Mesmo que ateu, o libertário que ama a liberdade deveria, no mínimo, respeitar — e, idealmente, redescobrir — essas raízes cristãs. Pois sem fé, restam apenas o niilismo e o relativismo, que, eventualmente, desaguam na servidão.
Como nos ensina a tradição: Ubi fides ibi libertas — onde há fé, há liberdade.

2025-05-09 13:56:57Someone asked for my thoughts, so I’ll share them thoughtfully. I’m not here to dictate how to promote Nostr—I’m still learning about it myself. While I’m not new to Nostr, freedom tech is a newer space for me. I’m skilled at advocating for topics I deeply understand, but freedom tech isn’t my expertise, so take my words with a grain of salt. Nothing I say is set in stone.
Those who need Nostr the most are the ones most vulnerable to censorship on other platforms right now. Reaching them requires real-time awareness of global issues and the dynamic relationships between governments and tech providers, which can shift suddenly. Effective Nostr promoters must grasp this and adapt quickly.
The best messengers are people from or closely tied to these at-risk regions—those who truly understand the local political and cultural dynamics. They can connect with those in need when tensions rise. Ideal promoters are rational, trustworthy, passionate about Nostr, but above all, dedicated to amplifying people’s voices when it matters most.
Forget influencers, corporate-backed figures, or traditional online PR—it comes off as inauthentic, corny, desperate and forced. Nostr’s promotion should be grassroots and organic, driven by a few passionate individuals who believe in Nostr and the communities they serve.
The idea that “people won’t join Nostr due to lack of reach” is nonsense. Everyone knows X’s “reach” is mostly with bots. If humans want real conversations, Nostr is the place. X is great for propaganda, but Nostr is for the authentic voices of the people.
Those spreading Nostr must be so passionate they’re willing to onboard others, which is time-consuming but rewarding for the right person. They’ll need to make Nostr and onboarding a core part of who they are. I see no issue with that level of dedication. I’ve been known to get that way myself at times. It’s fun for some folks.
With love, I suggest not adding Bitcoin promotion with Nostr outreach. Zaps already integrate that element naturally. (Still promote within the Bitcoin ecosystem, but this is about reaching vulnerable voices who needed Nostr yesterday.)
To promote Nostr, forget conventional strategies. “Influencers” aren’t the answer. “Influencers” are not the future. A trusted local community member has real influence—reach them. Connect with people seeking Nostr’s benefits but lacking the technical language to express it. This means some in the Nostr community might need to step outside of the Bitcoin bubble, which is uncomfortable but necessary. Thank you in advance to those who are willing to do that.
I don’t know who is paid to promote Nostr, if anyone. This piece isn’t shade. But it’s exhausting to see innocent voices globally silenced on corporate platforms like X while Nostr exists. Last night, I wondered: how many more voices must be censored before the Nostr community gets uncomfortable and thinks creatively to reach the vulnerable?
A warning: the global need for censorship-resistant social media is undeniable. If Nostr doesn’t make itself known, something else will fill that void. Let’s start this conversation.

2025-04-28 00:48:57I have been recently building NFDB, a new relay DB. This post is meant as a short overview.
Regular relays have challenges
Current relay software have significant challenges, which I have experienced when hosting Nostr.land: - Scalability is only supported by adding full replicas, which does not scale to large relays. - Most relays use slow databases and are not optimized for large scale usage. - Search is near-impossible to implement on standard relays. - Privacy features such as NIP-42 are lacking. - Regular DB maintenance tasks on normal relays require extended downtime. - Fault-tolerance is implemented, if any, using a load balancer, which is limited. - Personalization and advanced filtering is not possible. - Local caching is not supported.
NFDB: A scalable database for large relays
NFDB is a new database meant for medium-large scale relays, built on FoundationDB that provides: - Near-unlimited scalability - Extended fault tolerance - Instant loading - Better search - Better personalization - and more.
Search
NFDB has extended search capabilities including: - Semantic search: Search for meaning, not words. - Interest-based search: Highlight content you care about. - Multi-faceted queries: Easily filter by topic, author group, keywords, and more at the same time. - Wide support for event kinds, including users, articles, etc.
Personalization
NFDB allows significant personalization: - Customized algorithms: Be your own algorithm. - Spam filtering: Filter content to your WoT, and use advanced spam filters. - Topic mutes: Mute topics, not keywords. - Media filtering: With Nostr.build, you will be able to filter NSFW and other content - Low data mode: Block notes that use high amounts of cellular data. - and more
Other
NFDB has support for many other features such as: - NIP-42: Protect your privacy with private drafts and DMs - Microrelays: Easily deploy your own personal microrelay - Containers: Dedicated, fast storage for discoverability events such as relay lists
Calcite: A local microrelay database
Calcite is a lightweight, local version of NFDB that is meant for microrelays and caching, meant for thousands of personal microrelays.
Calcite HA is an additional layer that allows live migration and relay failover in under 30 seconds, providing higher availability compared to current relays with greater simplicity. Calcite HA is enabled in all Calcite deployments.
For zero-downtime, NFDB is recommended.
Noswhere SmartCache
Relays are fixed in one location, but users can be anywhere.
Noswhere SmartCache is a CDN for relays that dynamically caches data on edge servers closest to you, allowing: - Multiple regions around the world - Improved throughput and performance - Faster loading times
routerd
routerd
is a custom load-balancer optimized for Nostr relays, integrated with SmartCache.routerd
is specifically integrated with NFDB and Calcite HA to provide fast failover and high performance.Ending notes
NFDB is planned to be deployed to Nostr.land in the coming weeks.
A lot more is to come. 👀️️️️️️

I'm pretty sure Ben called Caruso the "Bald Mamba" in this video, which is an awesome nickname for him.
Great walkthrough of the adjustments made over the course of seven games to try to disrupt Joker, culminating with putting Caruso (who's 100 lbs lighter and 6 inches shorter) on him.

2025-04-26 10:16:21O Contexto Legal Brasileiro e o Consentimento
No ordenamento jurídico brasileiro, o consentimento do ofendido pode, em certas circunstâncias, afastar a ilicitude de um ato que, sem ele, configuraria crime (como lesão corporal leve, prevista no Art. 129 do Código Penal). Contudo, o consentimento tem limites claros: não é válido para bens jurídicos indisponíveis, como a vida, e sua eficácia é questionável em casos de lesões corporais graves ou gravíssimas.
A prática de BDSM consensual situa-se em uma zona complexa. Em tese, se ambos os parceiros são adultos, capazes, e consentiram livre e informadamente nos atos praticados, sem que resultem em lesões graves permanentes ou risco de morte não consentido, não haveria crime. O desafio reside na comprovação desse consentimento, especialmente se uma das partes, posteriormente, o negar ou alegar coação.
A Lei Maria da Penha (Lei nº 11.340/2006)
A Lei Maria da Penha é um marco fundamental na proteção da mulher contra a violência doméstica e familiar. Ela estabelece mecanismos para coibir e prevenir tal violência, definindo suas formas (física, psicológica, sexual, patrimonial e moral) e prevendo medidas protetivas de urgência.
Embora essencial, a aplicação da lei em contextos de BDSM pode ser delicada. Uma alegação de violência por parte da mulher, mesmo que as lesões ou situações decorram de práticas consensuais, tende a receber atenção prioritária das autoridades, dada a presunção de vulnerabilidade estabelecida pela lei. Isso pode criar um cenário onde o parceiro masculino enfrenta dificuldades significativas em demonstrar a natureza consensual dos atos, especialmente se não houver provas robustas pré-constituídas.
Outros riscos:
Lesão corporal grave ou gravíssima (art. 129, §§ 1º e 2º, CP), não pode ser justificada pelo consentimento, podendo ensejar persecução penal.
Crimes contra a dignidade sexual (arts. 213 e seguintes do CP) são de ação pública incondicionada e independem de representação da vítima para a investigação e denúncia.
Riscos de Falsas Acusações e Alegação de Coação Futura
Os riscos para os praticantes de BDSM, especialmente para o parceiro que assume o papel dominante ou que inflige dor/restrição (frequentemente, mas não exclusivamente, o homem), podem surgir de diversas frentes:
- Acusações Externas: Vizinhos, familiares ou amigos que desconhecem a natureza consensual do relacionamento podem interpretar sons, marcas ou comportamentos como sinais de abuso e denunciar às autoridades.
- Alegações Futuras da Parceira: Em caso de término conturbado, vingança, arrependimento ou mudança de perspectiva, a parceira pode reinterpretar as práticas passadas como abuso e buscar reparação ou retaliação através de uma denúncia. A alegação pode ser de que o consentimento nunca existiu ou foi viciado.
- Alegação de Coação: Uma das formas mais complexas de refutar é a alegação de que o consentimento foi obtido mediante coação (física, moral, psicológica ou econômica). A parceira pode alegar, por exemplo, que se sentia pressionada, intimidada ou dependente, e que seu "sim" não era genuíno. Provar a ausência de coação a posteriori é extremamente difícil.
- Ingenuidade e Vulnerabilidade Masculina: Muitos homens, confiando na dinâmica consensual e na parceira, podem negligenciar a necessidade de precauções. A crença de que "isso nunca aconteceria comigo" ou a falta de conhecimento sobre as implicações legais e o peso processual de uma acusação no âmbito da Lei Maria da Penha podem deixá-los vulneráveis. A presença de marcas físicas, mesmo que consentidas, pode ser usada como evidência de agressão, invertendo o ônus da prova na prática, ainda que não na teoria jurídica.
Estratégias de Prevenção e Mitigação
Não existe um método infalível para evitar completamente o risco de uma falsa acusação, mas diversas medidas podem ser adotadas para construir um histórico de consentimento e reduzir vulnerabilidades:
- Comunicação Explícita e Contínua: A base de qualquer prática BDSM segura é a comunicação constante. Negociar limites, desejos, palavras de segurança ("safewords") e expectativas antes, durante e depois das cenas é crucial. Manter registros dessas negociações (e-mails, mensagens, diários compartilhados) pode ser útil.
-
Documentação do Consentimento:
-
Contratos de Relacionamento/Cena: Embora a validade jurídica de "contratos BDSM" seja discutível no Brasil (não podem afastar normas de ordem pública), eles servem como forte evidência da intenção das partes, da negociação detalhada de limites e do consentimento informado. Devem ser claros, datados, assinados e, idealmente, reconhecidos em cartório (para prova de data e autenticidade das assinaturas).
-
Registros Audiovisuais: Gravar (com consentimento explícito para a gravação) discussões sobre consentimento e limites antes das cenas pode ser uma prova poderosa. Gravar as próprias cenas é mais complexo devido a questões de privacidade e potencial uso indevido, mas pode ser considerado em casos específicos, sempre com consentimento mútuo documentado para a gravação.
Importante: a gravação deve ser com ciência da outra parte, para não configurar violação da intimidade (art. 5º, X, da Constituição Federal e art. 20 do Código Civil).
-
-
Testemunhas: Em alguns contextos de comunidade BDSM, a presença de terceiros de confiança durante negociações ou mesmo cenas pode servir como testemunho, embora isso possa alterar a dinâmica íntima do casal.
- Estabelecimento Claro de Limites e Palavras de Segurança: Definir e respeitar rigorosamente os limites (o que é permitido, o que é proibido) e as palavras de segurança é fundamental. O desrespeito a uma palavra de segurança encerra o consentimento para aquele ato.
- Avaliação Contínua do Consentimento: O consentimento não é um cheque em branco; ele deve ser entusiástico, contínuo e revogável a qualquer momento. Verificar o bem-estar do parceiro durante a cena ("check-ins") é essencial.
- Discrição e Cuidado com Evidências Físicas: Ser discreto sobre a natureza do relacionamento pode evitar mal-entendidos externos. Após cenas que deixem marcas, é prudente que ambos os parceiros estejam cientes e de acordo, talvez documentando por fotos (com data) e uma nota sobre a consensualidade da prática que as gerou.
- Aconselhamento Jurídico Preventivo: Consultar um advogado especializado em direito de família e criminal, com sensibilidade para dinâmicas de relacionamento alternativas, pode fornecer orientação personalizada sobre as melhores formas de documentar o consentimento e entender os riscos legais específicos.
Observações Importantes
- Nenhuma documentação substitui a necessidade de consentimento real, livre, informado e contínuo.
- A lei brasileira protege a "integridade física" e a "dignidade humana". Práticas que resultem em lesões graves ou que violem a dignidade de forma não consentida (ou com consentimento viciado) serão ilegais, independentemente de qualquer acordo prévio.
- Em caso de acusação, a existência de documentação robusta de consentimento não garante a absolvição, mas fortalece significativamente a defesa, ajudando a demonstrar a natureza consensual da relação e das práticas.
-
A alegação de coação futura é particularmente difícil de prevenir apenas com documentos. Um histórico consistente de comunicação aberta (whatsapp/telegram/e-mails), respeito mútuo e ausência de dependência ou controle excessivo na relação pode ajudar a contextualizar a dinâmica como não coercitiva.
-
Cuidado com Marcas Visíveis e Lesões Graves Práticas que resultam em hematomas severos ou lesões podem ser interpretadas como agressão, mesmo que consentidas. Evitar excessos protege não apenas a integridade física, mas também evita questionamentos legais futuros.
O que vem a ser consentimento viciado
No Direito, consentimento viciado é quando a pessoa concorda com algo, mas a vontade dela não é livre ou plena — ou seja, o consentimento existe formalmente, mas é defeituoso por alguma razão.
O Código Civil brasileiro (art. 138 a 165) define várias formas de vício de consentimento. As principais são:
Erro: A pessoa se engana sobre o que está consentindo. (Ex.: A pessoa acredita que vai participar de um jogo leve, mas na verdade é exposta a práticas pesadas.)
Dolo: A pessoa é enganada propositalmente para aceitar algo. (Ex.: Alguém mente sobre o que vai acontecer durante a prática.)
Coação: A pessoa é forçada ou ameaçada a consentir. (Ex.: "Se você não aceitar, eu termino com você" — pressão emocional forte pode ser vista como coação.)
Estado de perigo ou lesão: A pessoa aceita algo em situação de necessidade extrema ou abuso de sua vulnerabilidade. (Ex.: Alguém em situação emocional muito fragilizada é induzida a aceitar práticas que normalmente recusaria.)
No contexto de BDSM, isso é ainda mais delicado: Mesmo que a pessoa tenha "assinado" um contrato ou dito "sim", se depois ela alegar que seu consentimento foi dado sob medo, engano ou pressão psicológica, o consentimento pode ser considerado viciado — e, portanto, juridicamente inválido.
Isso tem duas implicações sérias:
-
O crime não se descaracteriza: Se houver vício, o consentimento é ignorado e a prática pode ser tratada como crime normal (lesão corporal, estupro, tortura, etc.).
-
A prova do consentimento precisa ser sólida: Mostrando que a pessoa estava informada, lúcida, livre e sem qualquer tipo de coação.
Consentimento viciado é quando a pessoa concorda formalmente, mas de maneira enganada, forçada ou pressionada, tornando o consentimento inútil para efeitos jurídicos.
Conclusão
Casais que praticam BDSM consensual no Brasil navegam em um terreno que exige não apenas confiança mútua e comunicação excepcional, mas também uma consciência aguçada das complexidades legais e dos riscos de interpretações equivocadas ou acusações mal-intencionadas. Embora o BDSM seja uma expressão legítima da sexualidade humana, sua prática no Brasil exige responsabilidade redobrada. Ter provas claras de consentimento, manter a comunicação aberta e agir com prudência são formas eficazes de se proteger de falsas alegações e preservar a liberdade e a segurança de todos os envolvidos. Embora leis controversas como a Maria da Penha sejam "vitais" para a proteção contra a violência real, os praticantes de BDSM, e em particular os homens nesse contexto, devem adotar uma postura proativa e prudente para mitigar os riscos inerentes à potencial má interpretação ou instrumentalização dessas práticas e leis, garantindo que a expressão de sua consensualidade esteja resguardada na medida do possível.
Importante: No Brasil, mesmo com tudo isso, o Ministério Público pode denunciar por crime como lesão corporal grave, estupro ou tortura, independente de consentimento. Então a prudência nas práticas é fundamental.

2025-04-15 11:03:15Prelude
I wrote this post differently than any of my others. It started with a discussion with AI on an OPSec-inspired review of separation of powers, and evolved into quite an exciting debate! I asked Grok to write up a summary in my overall writing style, which it got pretty well. I've decided to post it exactly as-is. Ultimately, I think there are two solid ideas driving my stance here:
- Perfect is the enemy of the good
- Failure is the crucible of success
Beyond that, just some hard-core belief in freedom, separation of powers, and operating from self-interest.
Intro
Alright, buckle up. I’ve been chewing on this idea for a while, and it’s time to spit it out. Let’s look at the U.S. government like I’d look at a codebase under a cybersecurity audit—OPSEC style, no fluff. Forget the endless debates about what politicians should do. That’s noise. I want to talk about what they can do, the raw powers baked into the system, and why we should stop pretending those powers are sacred. If there’s a hole, either patch it or exploit it. No half-measures. And yeah, I’m okay if the whole thing crashes a bit—failure’s a feature, not a bug.
The Filibuster: A Security Rule with No Teeth
You ever see a firewall rule that’s more theater than protection? That’s the Senate filibuster. Everyone acts like it’s this untouchable guardian of democracy, but here’s the deal: a simple majority can torch it any day. It’s not a law; it’s a Senate preference, like choosing tabs over spaces. When people call killing it the “nuclear option,” I roll my eyes. Nuclear? It’s a button labeled “press me.” If a party wants it gone, they’ll do it. So why the dance?
I say stop playing games. Get rid of the filibuster. If you’re one of those folks who thinks it’s the only thing saving us from tyranny, fine—push for a constitutional amendment to lock it in. That’s a real patch, not a Post-it note. Until then, it’s just a vulnerability begging to be exploited. Every time a party threatens to nuke it, they’re admitting it’s not essential. So let’s stop pretending and move on.
Supreme Court Packing: Because Nine’s Just a Number
Here’s another fun one: the Supreme Court. Nine justices, right? Sounds official. Except it’s not. The Constitution doesn’t say nine—it’s silent on the number. Congress could pass a law tomorrow to make it 15, 20, or 42 (hitchhiker’s reference, anyone?). Packing the court is always on the table, and both sides know it. It’s like a root exploit just sitting there, waiting for someone to log in.
So why not call the bluff? If you’re in power—say, Trump’s back in the game—say, “I’m packing the court unless we amend the Constitution to fix it at nine.” Force the issue. No more shadowboxing. And honestly? The court’s got way too much power anyway. It’s not supposed to be a super-legislature, but here we are, with justices’ ideologies driving the bus. That’s a bug, not a feature. If the court weren’t such a kingmaker, packing it wouldn’t even matter. Maybe we should be talking about clipping its wings instead of just its size.
The Executive Should Go Full Klingon
Let’s talk presidents. I’m not saying they should wear Klingon armor and start shouting “Qapla’!”—though, let’s be real, that’d be awesome. I’m saying the executive should use every scrap of power the Constitution hands them. Enforce the laws you agree with, sideline the ones you don’t. If Congress doesn’t like it, they’ve got tools: pass new laws, override vetoes, or—here’s the big one—cut the budget. That’s not chaos; that’s the system working as designed.
Right now, the real problem isn’t the president overreaching; it’s the bureaucracy. It’s like a daemon running in the background, eating CPU and ignoring the user. The president’s supposed to be the one steering, but the administrative state’s got its own agenda. Let the executive flex, push the limits, and force Congress to check it. Norms? Pfft. The Constitution’s the spec sheet—stick to it.
Let the System Crash
Here’s where I get a little spicy: I’m totally fine if the government grinds to a halt. Deadlock isn’t a disaster; it’s a feature. If the branches can’t agree, let the president veto, let Congress starve the budget, let enforcement stall. Don’t tell me about “essential services.” Nothing’s so critical it can’t take a breather. Shutdowns force everyone to the table—debate, compromise, or expose who’s dropping the ball. If the public loses trust? Good. They’ll vote out the clowns or live with the circus they elected.
Think of it like a server crash. Sometimes you need a hard reboot to clear the cruft. If voters keep picking the same bad admins, well, the country gets what it deserves. Failure’s the best teacher—way better than limping along on autopilot.
States Are the Real MVPs
If the feds fumble, states step up. Right now, states act like junior devs waiting for the lead engineer to sign off. Why? Federal money. It’s a leash, and it’s tight. Cut that cash, and states will remember they’re autonomous. Some will shine, others will tank—looking at you, California. And I’m okay with that. Let people flee to better-run states. No bailouts, no excuses. States are like competing startups: the good ones thrive, the bad ones pivot or die.
Could it get uneven? Sure. Some states might turn into sci-fi utopias while others look like a post-apocalyptic vidya game. That’s the point—competition sorts it out. Citizens can move, markets adjust, and failure’s a signal to fix your act.
Chaos Isn’t the Enemy
Yeah, this sounds messy. States ignoring federal law, external threats poking at our seams, maybe even a constitutional crisis. I’m not scared. The Supreme Court’s there to referee interstate fights, and Congress sets the rules for state-to-state play. But if it all falls apart? Still cool. States can sort it without a babysitter—it’ll be ugly, but freedom’s worth it. External enemies? They’ll either unify us or break us. If we can’t rally, we don’t deserve the win.
Centralizing power to avoid this is like rewriting your app in a single thread to prevent race conditions—sure, it’s simpler, but you’re begging for a deadlock. Decentralized chaos lets states experiment, lets people escape, lets markets breathe. States competing to cut regulations to attract businesses? That’s a race to the bottom for red tape, but a race to the top for innovation—workers might gripe, but they’ll push back, and the tension’s healthy. Bring it—let the cage match play out. The Constitution’s checks are enough if we stop coddling the system.
Why This Matters
I’m not pitching a utopia. I’m pitching a stress test. The U.S. isn’t a fragile porcelain doll; it’s a rugged piece of hardware built to take some hits. Let it fail a little—filibuster, court, feds, whatever. Patch the holes with amendments if you want, or lean into the grind. Either way, stop fearing the crash. It’s how we debug the republic.
So, what’s your take? Ready to let the system rumble, or got a better way to secure the code? Hit me up—I’m all ears.

bash lsblk # Lista todos os diretorios montados.
Para criar o sistema de arquivos:
bash mkfs.btrfs -L "ThePool" -f /dev/sdx
Criando um subvolume:
bash btrfs subvolume create SubVol
Montando Sistema de Arquivos:
bash mount -o compress=zlib,subvol=SubVol,autodefrag /dev/sdx /mnt
Lista os discos formatados no diretório:
bash btrfs filesystem show /mnt
Adiciona novo disco ao subvolume:
bash btrfs device add -f /dev/sdy /mnt
Lista novamente os discos do subvolume:
bash btrfs filesystem show /mnt
Exibe uso dos discos do subvolume:
bash btrfs filesystem df /mnt
Balancea os dados entre os discos sobre raid1:
bash btrfs filesystem balance start -dconvert=raid1 -mconvert=raid1 /mnt
Scrub é uma passagem por todos os dados e metadados do sistema de arquivos e verifica as somas de verificação. Se uma cópia válida estiver disponível (perfis de grupo de blocos replicados), a danificada será reparada. Todas as cópias dos perfis replicados são validadas.
iniciar o processo de depuração :
bash btrfs scrub start /mnt
ver o status do processo de depuração Btrfs em execução:
bash btrfs scrub status /mnt
ver o status do scrub Btrfs para cada um dos dispositivos
bash btrfs scrub status -d / data btrfs scrub cancel / data
Para retomar o processo de depuração do Btrfs que você cancelou ou pausou:
btrfs scrub resume / data
Listando os subvolumes:
bash btrfs subvolume list /Reports
Criando um instantâneo dos subvolumes:
Aqui, estamos criando um instantâneo de leitura e gravação chamado snap de marketing do subvolume de marketing.
bash btrfs subvolume snapshot /Reports/marketing /Reports/marketing-snap
Além disso, você pode criar um instantâneo somente leitura usando o sinalizador -r conforme mostrado. O marketing-rosnap é um instantâneo somente leitura do subvolume de marketing
bash btrfs subvolume snapshot -r /Reports/marketing /Reports/marketing-rosnap
Forçar a sincronização do sistema de arquivos usando o utilitário 'sync'
Para forçar a sincronização do sistema de arquivos, invoque a opção de sincronização conforme mostrado. Observe que o sistema de arquivos já deve estar montado para que o processo de sincronização continue com sucesso.
bash btrfs filsystem sync /Reports
Para excluir o dispositivo do sistema de arquivos, use o comando device delete conforme mostrado.
bash btrfs device delete /dev/sdc /Reports
Para sondar o status de um scrub, use o comando scrub status com a opção -dR .
bash btrfs scrub status -dR / Relatórios
Para cancelar a execução do scrub, use o comando scrub cancel .
bash $ sudo btrfs scrub cancel / Reports
Para retomar ou continuar com uma depuração interrompida anteriormente, execute o comando de cancelamento de depuração
bash sudo btrfs scrub resume /Reports
mostra o uso do dispositivo de armazenamento:
btrfs filesystem usage /data
Para distribuir os dados, metadados e dados do sistema em todos os dispositivos de armazenamento do RAID (incluindo o dispositivo de armazenamento recém-adicionado) montados no diretório /data , execute o seguinte comando:
sudo btrfs balance start --full-balance /data
Pode demorar um pouco para espalhar os dados, metadados e dados do sistema em todos os dispositivos de armazenamento do RAID se ele contiver muitos dados.
Opções importantes de montagem Btrfs
Nesta seção, vou explicar algumas das importantes opções de montagem do Btrfs. Então vamos começar.
As opções de montagem Btrfs mais importantes são:
**1. acl e noacl
**ACL gerencia permissões de usuários e grupos para os arquivos/diretórios do sistema de arquivos Btrfs.
A opção de montagem acl Btrfs habilita ACL. Para desabilitar a ACL, você pode usar a opção de montagem noacl .
Por padrão, a ACL está habilitada. Portanto, o sistema de arquivos Btrfs usa a opção de montagem acl por padrão.
**2. autodefrag e noautodefrag
**Desfragmentar um sistema de arquivos Btrfs melhorará o desempenho do sistema de arquivos reduzindo a fragmentação de dados.
A opção de montagem autodefrag permite a desfragmentação automática do sistema de arquivos Btrfs.
A opção de montagem noautodefrag desativa a desfragmentação automática do sistema de arquivos Btrfs.
Por padrão, a desfragmentação automática está desabilitada. Portanto, o sistema de arquivos Btrfs usa a opção de montagem noautodefrag por padrão.
**3. compactar e compactar-forçar
**Controla a compactação de dados no nível do sistema de arquivos do sistema de arquivos Btrfs.
A opção compactar compacta apenas os arquivos que valem a pena compactar (se compactar o arquivo economizar espaço em disco).
A opção compress-force compacta todos os arquivos do sistema de arquivos Btrfs, mesmo que a compactação do arquivo aumente seu tamanho.
O sistema de arquivos Btrfs suporta muitos algoritmos de compactação e cada um dos algoritmos de compactação possui diferentes níveis de compactação.
Os algoritmos de compactação suportados pelo Btrfs são: lzo , zlib (nível 1 a 9) e zstd (nível 1 a 15).
Você pode especificar qual algoritmo de compactação usar para o sistema de arquivos Btrfs com uma das seguintes opções de montagem:
- compress=algoritmo:nível
- compress-force=algoritmo:nível
Para obter mais informações, consulte meu artigo Como habilitar a compactação do sistema de arquivos Btrfs .
**4. subvol e subvolid
**Estas opções de montagem são usadas para montar separadamente um subvolume específico de um sistema de arquivos Btrfs.
A opção de montagem subvol é usada para montar o subvolume de um sistema de arquivos Btrfs usando seu caminho relativo.
A opção de montagem subvolid é usada para montar o subvolume de um sistema de arquivos Btrfs usando o ID do subvolume.
Para obter mais informações, consulte meu artigo Como criar e montar subvolumes Btrfs .
**5. dispositivo
A opção de montagem de dispositivo** é usada no sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs.
Em alguns casos, o sistema operacional pode falhar ao detectar os dispositivos de armazenamento usados em um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs. Nesses casos, você pode usar a opção de montagem do dispositivo para especificar os dispositivos que deseja usar para o sistema de arquivos de vários dispositivos Btrfs ou RAID.
Você pode usar a opção de montagem de dispositivo várias vezes para carregar diferentes dispositivos de armazenamento para o sistema de arquivos de vários dispositivos Btrfs ou RAID.
Você pode usar o nome do dispositivo (ou seja, sdb , sdc ) ou UUID , UUID_SUB ou PARTUUID do dispositivo de armazenamento com a opção de montagem do dispositivo para identificar o dispositivo de armazenamento.
Por exemplo,
- dispositivo=/dev/sdb
- dispositivo=/dev/sdb,dispositivo=/dev/sdc
- dispositivo=UUID_SUB=490a263d-eb9a-4558-931e-998d4d080c5d
- device=UUID_SUB=490a263d-eb9a-4558-931e-998d4d080c5d,device=UUID_SUB=f7ce4875-0874-436a-b47d-3edef66d3424
**6. degraded
A opção de montagem degradada** permite que um RAID Btrfs seja montado com menos dispositivos de armazenamento do que o perfil RAID requer.
Por exemplo, o perfil raid1 requer a presença de 2 dispositivos de armazenamento. Se um dos dispositivos de armazenamento não estiver disponível em qualquer caso, você usa a opção de montagem degradada para montar o RAID mesmo que 1 de 2 dispositivos de armazenamento esteja disponível.
**7. commit
A opção commit** mount é usada para definir o intervalo (em segundos) dentro do qual os dados serão gravados no dispositivo de armazenamento.
O padrão é definido como 30 segundos.
Para definir o intervalo de confirmação para 15 segundos, você pode usar a opção de montagem commit=15 (digamos).
**8. ssd e nossd
A opção de montagem ssd** informa ao sistema de arquivos Btrfs que o sistema de arquivos está usando um dispositivo de armazenamento SSD, e o sistema de arquivos Btrfs faz a otimização SSD necessária.
A opção de montagem nossd desativa a otimização do SSD.
O sistema de arquivos Btrfs detecta automaticamente se um SSD é usado para o sistema de arquivos Btrfs. Se um SSD for usado, a opção de montagem de SSD será habilitada. Caso contrário, a opção de montagem nossd é habilitada.
**9. ssd_spread e nossd_spread
A opção de montagem ssd_spread** tenta alocar grandes blocos contínuos de espaço não utilizado do SSD. Esse recurso melhora o desempenho de SSDs de baixo custo (baratos).
A opção de montagem nossd_spread desativa o recurso ssd_spread .
O sistema de arquivos Btrfs detecta automaticamente se um SSD é usado para o sistema de arquivos Btrfs. Se um SSD for usado, a opção de montagem ssd_spread será habilitada. Caso contrário, a opção de montagem nossd_spread é habilitada.
**10. descarte e nodiscard
Se você estiver usando um SSD que suporte TRIM enfileirado assíncrono (SATA rev3.1), a opção de montagem de descarte** permitirá o descarte de blocos de arquivos liberados. Isso melhorará o desempenho do SSD.
Se o SSD não suportar TRIM enfileirado assíncrono, a opção de montagem de descarte prejudicará o desempenho do SSD. Nesse caso, a opção de montagem nodiscard deve ser usada.
Por padrão, a opção de montagem nodiscard é usada.
**11. norecovery
Se a opção de montagem norecovery** for usada, o sistema de arquivos Btrfs não tentará executar a operação de recuperação de dados no momento da montagem.
**12. usebackuproot e nousebackuproot
Se a opção de montagem usebackuproot for usada, o sistema de arquivos Btrfs tentará recuperar qualquer raiz de árvore ruim/corrompida no momento da montagem. O sistema de arquivos Btrfs pode armazenar várias raízes de árvore no sistema de arquivos. A opção de montagem usebackuproot** procurará uma boa raiz de árvore e usará a primeira boa que encontrar.
A opção de montagem nousebackuproot não verificará ou recuperará raízes de árvore inválidas/corrompidas no momento da montagem. Este é o comportamento padrão do sistema de arquivos Btrfs.
**13. space_cache, space_cache=version, nospace_cache e clear_cache
A opção de montagem space_cache** é usada para controlar o cache de espaço livre. O cache de espaço livre é usado para melhorar o desempenho da leitura do espaço livre do grupo de blocos do sistema de arquivos Btrfs na memória (RAM).
O sistema de arquivos Btrfs suporta 2 versões do cache de espaço livre: v1 (padrão) e v2
O mecanismo de cache de espaço livre v2 melhora o desempenho de sistemas de arquivos grandes (tamanho de vários terabytes).
Você pode usar a opção de montagem space_cache=v1 para definir a v1 do cache de espaço livre e a opção de montagem space_cache=v2 para definir a v2 do cache de espaço livre.
A opção de montagem clear_cache é usada para limpar o cache de espaço livre.
Quando o cache de espaço livre v2 é criado, o cache deve ser limpo para criar um cache de espaço livre v1 .
Portanto, para usar o cache de espaço livre v1 após a criação do cache de espaço livre v2 , as opções de montagem clear_cache e space_cache=v1 devem ser combinadas: clear_cache,space_cache=v1
A opção de montagem nospace_cache é usada para desabilitar o cache de espaço livre.
Para desabilitar o cache de espaço livre após a criação do cache v1 ou v2 , as opções de montagem nospace_cache e clear_cache devem ser combinadas: clear_cache,nosapce_cache
**14. skip_balance
Por padrão, a operação de balanceamento interrompida/pausada de um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs será retomada automaticamente assim que o sistema de arquivos Btrfs for montado. Para desabilitar a retomada automática da operação de equilíbrio interrompido/pausado em um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs, você pode usar a opção de montagem skip_balance .**
**15. datacow e nodatacow
A opção datacow** mount habilita o recurso Copy-on-Write (CoW) do sistema de arquivos Btrfs. É o comportamento padrão.
Se você deseja desabilitar o recurso Copy-on-Write (CoW) do sistema de arquivos Btrfs para os arquivos recém-criados, monte o sistema de arquivos Btrfs com a opção de montagem nodatacow .
**16. datasum e nodatasum
A opção datasum** mount habilita a soma de verificação de dados para arquivos recém-criados do sistema de arquivos Btrfs. Este é o comportamento padrão.
Se você não quiser que o sistema de arquivos Btrfs faça a soma de verificação dos dados dos arquivos recém-criados, monte o sistema de arquivos Btrfs com a opção de montagem nodatasum .
Perfis Btrfs
Um perfil Btrfs é usado para informar ao sistema de arquivos Btrfs quantas cópias dos dados/metadados devem ser mantidas e quais níveis de RAID devem ser usados para os dados/metadados. O sistema de arquivos Btrfs contém muitos perfis. Entendê-los o ajudará a configurar um RAID Btrfs da maneira que você deseja.
Os perfis Btrfs disponíveis são os seguintes:
single : Se o perfil único for usado para os dados/metadados, apenas uma cópia dos dados/metadados será armazenada no sistema de arquivos, mesmo se você adicionar vários dispositivos de armazenamento ao sistema de arquivos. Assim, 100% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser utilizado.
dup : Se o perfil dup for usado para os dados/metadados, cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos manterá duas cópias dos dados/metadados. Assim, 50% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser utilizado.
raid0 : No perfil raid0 , os dados/metadados serão divididos igualmente em todos os dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, não haverá dados/metadados redundantes (duplicados). Assim, 100% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser usado. Se, em qualquer caso, um dos dispositivos de armazenamento falhar, todo o sistema de arquivos será corrompido. Você precisará de pelo menos dois dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid0 .
raid1 : No perfil raid1 , duas cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a uma falha de unidade. Mas você pode usar apenas 50% do espaço total em disco. Você precisará de pelo menos dois dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1 .
raid1c3 : No perfil raid1c3 , três cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a duas falhas de unidade, mas você pode usar apenas 33% do espaço total em disco. Você precisará de pelo menos três dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1c3 .
raid1c4 : No perfil raid1c4 , quatro cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a três falhas de unidade, mas você pode usar apenas 25% do espaço total em disco. Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1c4 .
raid10 : No perfil raid10 , duas cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos, como no perfil raid1 . Além disso, os dados/metadados serão divididos entre os dispositivos de armazenamento, como no perfil raid0 .
O perfil raid10 é um híbrido dos perfis raid1 e raid0 . Alguns dos dispositivos de armazenamento formam arrays raid1 e alguns desses arrays raid1 são usados para formar um array raid0 . Em uma configuração raid10 , o sistema de arquivos pode sobreviver a uma única falha de unidade em cada uma das matrizes raid1 .
Você pode usar 50% do espaço total em disco na configuração raid10 . Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid10 .
raid5 : No perfil raid5 , uma cópia dos dados/metadados será dividida entre os dispositivos de armazenamento. Uma única paridade será calculada e distribuída entre os dispositivos de armazenamento do array RAID.
Em uma configuração raid5 , o sistema de arquivos pode sobreviver a uma única falha de unidade. Se uma unidade falhar, você pode adicionar uma nova unidade ao sistema de arquivos e os dados perdidos serão calculados a partir da paridade distribuída das unidades em execução.
Você pode usar 1 00x(N-1)/N % do total de espaços em disco na configuração raid5 . Aqui, N é o número de dispositivos de armazenamento adicionados ao sistema de arquivos. Você precisará de pelo menos três dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid5 .
raid6 : No perfil raid6 , uma cópia dos dados/metadados será dividida entre os dispositivos de armazenamento. Duas paridades serão calculadas e distribuídas entre os dispositivos de armazenamento do array RAID.
Em uma configuração raid6 , o sistema de arquivos pode sobreviver a duas falhas de unidade ao mesmo tempo. Se uma unidade falhar, você poderá adicionar uma nova unidade ao sistema de arquivos e os dados perdidos serão calculados a partir das duas paridades distribuídas das unidades em execução.
Você pode usar 100x(N-2)/N % do espaço total em disco na configuração raid6 . Aqui, N é o número de dispositivos de armazenamento adicionados ao sistema de arquivos. Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid6 .

2025-04-09 21:19:39DAOs promised decentralization. They offered a system where every member could influence a project's direction, where money and power were transparently distributed, and decisions were made through voting. All of it recorded immutably on the blockchain, free from middlemen.
But something didn’t work out. In practice, most DAOs haven’t evolved into living, self-organizing organisms. They became something else: clubs where participation is unevenly distributed. Leaders remained - only now without formal titles. They hold influence through control over communications, task framing, and community dynamics. Centralization still exists, just wrapped in a new package.
But there's a second, less obvious problem. Crowds can’t create strategy. In DAOs, people vote for what "feels right to the majority." But strategy isn’t about what feels good - it’s about what’s necessary. Difficult, unpopular, yet forward-looking decisions often fail when put to a vote. A founder’s vision is a risk. But in healthy teams, it’s that risk that drives progress. In DAOs, risk is almost always diluted until it becomes something safe and vague.
Instead of empowering leaders, DAOs often neutralize them. This is why many DAOs resemble consensus machines. Everyone talks, debates, and participates, but very little actually gets done. One person says, “Let’s jump,” and five others respond, “Let’s discuss that first.” This dynamic might work for open forums, but not for action.
Decentralization works when there’s trust and delegation, not just voting. Until DAOs develop effective systems for assigning roles, taking ownership, and acting with flexibility, they will keep losing ground to old-fashioned startups led by charismatic founders with a clear vision.
We’ve seen this in many real-world cases. Take MakerDAO, one of the most mature and technically sophisticated DAOs. Its governance token (MKR) holders vote on everything from interest rates to protocol upgrades. While this has allowed for transparency and community involvement, the process is often slow and bureaucratic. Complex proposals stall. Strategic pivots become hard to implement. And in 2023, a controversial proposal to allocate billions to real-world assets passed only narrowly, after months of infighting - highlighting how vision and execution can get stuck in the mud of distributed governance.
On the other hand, Uniswap DAO, responsible for the largest decentralized exchange, raised governance participation only after launching a delegation system where token holders could choose trusted representatives. Still, much of the activity is limited to a small group of active contributors. The vast majority of token holders remain passive. This raises the question: is it really community-led, or just a formalized power structure with lower transparency?
Then there’s ConstitutionDAO, an experiment that went viral. It raised over $40 million in days to try and buy a copy of the U.S. Constitution. But despite the hype, the DAO failed to win the auction. Afterwards, it struggled with refund logistics, communication breakdowns, and confusion over governance. It was a perfect example of collective enthusiasm without infrastructure or planning - proof that a DAO can raise capital fast but still lack cohesion.
Not all efforts have failed. Projects like Gitcoin DAO have made progress by incentivizing small, individual contributions. Their quadratic funding mechanism rewards projects based on the number of contributors, not just the size of donations, helping to elevate grassroots initiatives. But even here, long-term strategy often falls back on a core group of organizers rather than broad community consensus.
The pattern is clear: when the stakes are low or the tasks are modular, DAOs can coordinate well. But when bold moves are needed—when someone has to take responsibility and act under uncertainty DAOs often freeze. In the name of consensus, they lose momentum.
That’s why the organization of the future can’t rely purely on decentralization. It must encourage individual initiative and the ability to take calculated risks. People need to see their contribution not just as a vote, but as a role with clear actions and expected outcomes. When the situation demands, they should be empowered to act first and present the results to the community afterwards allowing for both autonomy and accountability. That’s not a flaw in the system. It’s how real progress happens.

2025-04-05 16:58:58I’m drawn to extremities in art. The louder, the bolder, the more outrageous, the better. Bold art takes me out of the mundane into a whole new world where anything and everything is possible. Having grown up in the safety of the suburban midwest, I was a bit of a rebellious soul in search of the satiation that only came from the consumption of the outrageous. My inclination to find bold art draws me to NOSTR, because I believe NOSTR can be the place where the next generation of artistic pioneers go to express themselves. I also believe that as much as we are able, were should invite them to come create here.
My Background: A Small Side Story
My father was a professional gamer in the 80s, back when there was no money or glory in the avocation. He did get a bit of spotlight though after the fact: in the mid 2000’s there were a few parties making documentaries about that era of gaming as well as current arcade events (namely 2007’sChasing GhostsandThe King of Kong: A Fistful of Quarters). As a result of these documentaries, there was a revival in the arcade gaming scene. My family attended events related to the documentaries or arcade gaming and I became exposed to a lot of things I wouldn’t have been able to find. The producer ofThe King of Kong: A Fistful of Quarters had previously made a documentary calledNew York Dollwhich was centered around the life of bassist Arthur Kane. My 12 year old mind was blown: The New York Dolls were a glam-punk sensation dressed in drag. The music was from another planet. Johnny Thunders’ guitar playing was like Chuck Berry with more distortion and less filter. Later on I got to meet the Galaga record holder at the time, Phil Day, in Ottumwa Iowa. Phil is an Australian man of high intellect and good taste. He exposed me to great creators such as Nick Cave & The Bad Seeds, Shakespeare, Lou Reed, artists who created things that I had previously found inconceivable.
I believe this time period informed my current tastes and interests, but regrettably I think it also put coals on the fire of rebellion within. I stopped taking my parents and siblings seriously, the Christian faith of my family (which I now hold dearly to) seemed like a mundane sham, and I felt I couldn’t fit in with most people because of my avant-garde tastes. So I write this with the caveat that there should be a way to encourage these tastes in children without letting them walk down the wrong path. There is nothing inherently wrong with bold art, but I’d advise parents to carefully find ways to cultivate their children’s tastes without completely shutting them down and pushing them away as a result. My parents were very loving and patient during this time; I thank God for that.
With that out of the way, lets dive in to some bold artists:
Nicolas Cage: Actor
There is an excellent video by Wisecrack on Nicolas Cage that explains him better than I will, which I will linkhere. Nicolas Cage rejects the idea that good acting is tied to mere realism; all of his larger than life acting decisions are deliberate choices. When that clicked for me, I immediately realized the man is a genius. He borrows from Kabuki and German Expressionism, art forms that rely on exaggeration to get the message across. He has even created his own acting style, which he calls Nouveau Shamanic. He augments his imagination to go from acting to being. Rather than using the old hat of method acting, he transports himself to a new world mentally. The projects he chooses to partake in are based on his own interests or what he considers would be a challenge (making a bad script good for example). Thus it doesn’t matter how the end result comes out; he has already achieved his goal as an artist. Because of this and because certain directors don’t know how to use his talents, he has a noticeable amount of duds in his filmography. Dig around the duds, you’ll find some pure gold. I’d personally recommend the filmsPig, Joe, Renfield, and his Christmas film The Family Man.
Nick Cave: Songwriter
What a wild career this man has had! From the apocalyptic mayhem of his band The Birthday Party to the pensive atmosphere of his albumGhosteen, it seems like Nick Cave has tried everything. I think his secret sauce is that he’s always working. He maintains an excellent newsletter calledThe Red Hand Files, he has written screenplays such asLawless, he has written books, he has made great film scores such asThe Assassination of Jesse James by the Coward Robert Ford, the man is religiously prolific. I believe that one of the reasons he is prolific is that he’s not afraid to experiment. If he has an idea, he follows it through to completion. From the albumMurder Ballads(which is comprised of what the title suggests) to his rejected sequel toGladiator(Gladiator: Christ Killer), he doesn’t seem to be afraid to take anything on. This has led to some over the top works as well as some deeply personal works. Albums likeSkeleton TreeandGhosteenwere journeys through the grief of his son’s death. The Boatman’s Callis arguably a better break-up album than anything Taylor Swift has put out. He’s not afraid to be outrageous, he’s not afraid to offend, but most importantly he’s not afraid to be himself. Works I’d recommend include The Birthday Party’sLive 1981-82, Nick Cave & The Bad Seeds’The Boatman’s Call, and the filmLawless.
Jim Jarmusch: Director
I consider Jim’s films to be bold almost in an ironic sense: his works are bold in that they are, for the most part, anti-sensational. He has a rule that if his screenplays are criticized for a lack of action, he makes them even less eventful. Even with sensational settings his films feel very close to reality, and they demonstrate the beauty of everyday life. That's what is bold about his art to me: making the sensational grounded in reality while making everyday reality all the more special. Ghost Dog: The Way of the Samurai is about a modern-day African-American hitman who strictly follows the rules of the ancient Samurai, yet one can resonate with the humanity of a seemingly absurd character. Only Lovers Left Aliveis a vampire love story, but in the middle of a vampire romance one can see their their own relationships in a new deeply human light. Jim’s work reminds me that art reflects life, and that there is sacred beauty in seemingly mundane everyday life. I personally recommend his filmsPaterson,Down by Law, andCoffee and Cigarettes.
NOSTR: We Need Bold Art
NOSTR is in my opinion a path to a better future. In a world creeping slowly towards everything apps, I hope that the protocol where the individual owns their data wins over everything else. I love freedom and sovereignty. If NOSTR is going to win the race of everything apps, we need more than Bitcoin content. We need more than shirtless bros paying for bananas in foreign countries and exercising with girls who have seductive accents. Common people cannot see themselves in such a world. NOSTR needs to catch the attention of everyday people. I don’t believe that this can be accomplished merely by introducing more broadly relevant content; people are searching for content that speaks to them. I believe that NOSTR can and should attract artists of all kinds because NOSTR is one of the few places on the internet where artists can express themselves fearlessly. Getting zaps from NOSTR’s value-for-value ecosystem has far less friction than crowdfunding a creative project or pitching investors that will irreversibly modify an artist’s vision. Having a place where one can post their works without fear of censorship should be extremely enticing. Having a place where one can connect with fellow humans directly as opposed to a sea of bots should seem like the obvious solution. If NOSTR can become a safe haven for artists to express themselves and spread their work, I believe that everyday people will follow. The banker whose stressful job weighs on them will suddenly find joy with an original meme made by a great visual comedian. The programmer for a healthcare company who is drowning in hopeless mundanity could suddenly find a new lust for life by hearing the song of a musician who isn’t afraid to crowdfund their their next project by putting their lighting address on the streets of the internet. The excel guru who loves independent film may find that NOSTR is the best way to support non corporate movies. My closing statement: continue to encourage the artists in your life as I’m sure you have been, but while you’re at it give them the purple pill. You may very well be a part of building a better future.

2025-05-16 20:57:43Google says that Android 16 is slated to feature an optional high security mode. Cool.
Advanced Protection has a bunch of requested features that address the kinds of threats we worry about.
It's the kind of 'turn this one thing on if you face elevated risk' that we've been asking for from Google.
And likely reflects some learning after Google watched Apple 's Lockdown Mode play out. I see a lot of value in this..
Here are some features I'm excited to see play out:
The Intrusion Logging feature is interesting & is going to impose substantial cost on attackers trying to hide evidence of exploitation. Logs get e2ee encrypted into the cloud. This one is spicy.
The Offline Lock, Inactivity Reboot & USB protection will frustrate non-consensual attempts to physically grab device data.
Memory Tagging Extension is going to make a lot of attack & exploitation categories harder.
2G Network Protection & disabling Auto-connect to insecure networks are going to address categories of threat from things like IMSI catchers & hostile WiFi.
I'm curious about some other features such as:
Spam & Scam detection: Google messages feature that suggests message content awareness and some kind of scanning.
Scam detection for Phone by Google is interesting & coming later. The way it is described suggests phone conversation awareness. This also addresses a different category of threat than the stuff above. I can see it addressing a whole category of bad things that regular users (& high risk ones too!) face. Will be curious how privacy is addressed or if this done purely locally. Getting messy: Friction points? I see Google thinking these through, but I'm going to add a potential concern: what will users do when they encounter friction? Will they turn this off & forget to re-enable? We've seen users turn off iOS Lockdown Mode when they run into friction for specific websites or, say, legacy WiFi. They then forget to turn it back on. And stay vulnerable.
Bottom line: users disabling Apple's Lockdown Mode for a temporary thing & leaving it off because they forget to turn it on happens a lot. This is a serious % of users in my experience...
And should be factored into design decisions for similar modes. I feel like a good balance is a 'snooze button' or equivalent so that users can disable all/some features for a brief few minute period to do something they need to do, and then auto re-enable.
Winding up:
I'm excited to see how Android Advanced Protection plays with high risk users' experiences. I'm also super curious whether the spam/scam detection features may also be helpful to more vulnerable users (think: aging seniors)...
Niche but important:
Some users, esp. those that migrated to security & privacy-focused Android distros because of because of the absence of such a feature are clear candidates for it... But they may also voice privacy concerns around some of the screening features. Clear communication from the Google Security / Android team will be key here.

2025-03-18 20:47:50Warning: This piece contains a conversation about difficult topics. Please proceed with caution.
TL;DR please educate your children about online safety.
Julian Assange wrote in his 2012 book Cypherpunks, “This book is not a manifesto. There isn’t time for that. This book is a warning.” I read it a few times over the past summer. Those opening lines definitely stood out to me. I wish we had listened back then. He saw something about the internet that few had the ability to see. There are some individuals who are so close to a topic that when they speak, it’s difficult for others who aren’t steeped in it to visualize what they’re talking about. I didn’t read the book until more recently. If I had read it when it came out, it probably would have sounded like an unknown foreign language to me. Today it makes more sense.
This isn’t a manifesto. This isn’t a book. There is no time for that. It’s a warning and a possible solution from a desperate and determined survivor advocate who has been pulling and unraveling a thread for a few years. At times, I feel too close to this topic to make any sense trying to convey my pathway to my conclusions or thoughts to the general public. My hope is that if nothing else, I can convey my sense of urgency while writing this. This piece is a watchman’s warning.
When a child steps online, they are walking into a new world. A new reality. When you hand a child the internet, you are handing them possibilities—good, bad, and ugly. This is a conversation about lowering the potential of negative outcomes of stepping into that new world and how I came to these conclusions. I constantly compare the internet to the road. You wouldn’t let a young child run out into the road with no guidance or safety precautions. When you hand a child the internet without any type of guidance or safety measures, you are allowing them to play in rush hour, oncoming traffic. “Look left, look right for cars before crossing.” We almost all have been taught that as children. What are we taught as humans about safety before stepping into a completely different reality like the internet? Very little.
I could never really figure out why many folks in tech, privacy rights activists, and hackers seemed so cold to me while talking about online child sexual exploitation. I always figured that as a survivor advocate for those affected by these crimes, that specific, skilled group of individuals would be very welcoming and easy to talk to about such serious topics. I actually had one hacker laugh in my face when I brought it up while I was looking for answers. I thought maybe this individual thought I was accusing them of something I wasn’t, so I felt bad for asking. I was constantly extremely disappointed and would ask myself, “Why don’t they care? What could I say to make them care more? What could I say to make them understand the crisis and the level of suffering that happens as a result of the problem?”
I have been serving minor survivors of online child sexual exploitation for years. My first case serving a survivor of this specific crime was in 2018—a 13-year-old girl sexually exploited by a serial predator on Snapchat. That was my first glimpse into this side of the internet. I won a national award for serving the minor survivors of Twitter in 2023, but I had been working on that specific project for a few years. I was nominated by a lawyer representing two survivors in a legal battle against the platform. I’ve never really spoken about this before, but at the time it was a choice for me between fighting Snapchat or Twitter. I chose Twitter—or rather, Twitter chose me. I heard about the story of John Doe #1 and John Doe #2, and I was so unbelievably broken over it that I went to war for multiple years. I was and still am royally pissed about that case. As far as I was concerned, the John Doe #1 case proved that whatever was going on with corporate tech social media was so out of control that I didn’t have time to wait, so I got to work. It was reading the messages that John Doe #1 sent to Twitter begging them to remove his sexual exploitation that broke me. He was a child begging adults to do something. A passion for justice and protecting kids makes you do wild things. I was desperate to find answers about what happened and searched for solutions. In the end, the platform Twitter was purchased. During the acquisition, I just asked Mr. Musk nicely to prioritize the issue of detection and removal of child sexual exploitation without violating digital privacy rights or eroding end-to-end encryption. Elon thanked me multiple times during the acquisition, made some changes, and I was thanked by others on the survivors’ side as well.
I still feel that even with the progress made, I really just scratched the surface with Twitter, now X. I left that passion project when I did for a few reasons. I wanted to give new leadership time to tackle the issue. Elon Musk made big promises that I knew would take a while to fulfill, but mostly I had been watching global legislation transpire around the issue, and frankly, the governments are willing to go much further with X and the rest of corporate tech than I ever would. My work begging Twitter to make changes with easier reporting of content, detection, and removal of child sexual exploitation material—without violating privacy rights or eroding end-to-end encryption—and advocating for the minor survivors of the platform went as far as my principles would have allowed. I’m grateful for that experience. I was still left with a nagging question: “How did things get so bad with Twitter where the John Doe #1 and John Doe #2 case was able to happen in the first place?” I decided to keep looking for answers. I decided to keep pulling the thread.
I never worked for Twitter. This is often confusing for folks. I will say that despite being disappointed in the platform’s leadership at times, I loved Twitter. I saw and still see its value. I definitely love the survivors of the platform, but I also loved the platform. I was a champion of the platform’s ability to give folks from virtually around the globe an opportunity to speak and be heard.
I want to be clear that John Doe #1 really is my why. He is the inspiration. I am writing this because of him. He represents so many globally, and I’m still inspired by his bravery. One child’s voice begging adults to do something—I’m an adult, I heard him. I’d go to war a thousand more lifetimes for that young man, and I don’t even know his name. Fighting has been personally dark at times; I’m not even going to try to sugarcoat it, but it has been worth it.
The data surrounding the very real crime of online child sexual exploitation is available to the public online at any time for anyone to see. I’d encourage you to go look at the data for yourself. I believe in encouraging folks to check multiple sources so that you understand the full picture. If you are uncomfortable just searching around the internet for information about this topic, use the terms “CSAM,” “CSEM,” “SG-CSEM,” or “AI Generated CSAM.” The numbers don’t lie—it’s a nightmare that’s out of control. It’s a big business. The demand is high, and unfortunately, business is booming. Organizations collect the data, tech companies often post their data, governments report frequently, and the corporate press has covered a decent portion of the conversation, so I’m sure you can find a source that you trust.
Technology is changing rapidly, which is great for innovation as a whole but horrible for the crime of online child sexual exploitation. Those wishing to exploit the vulnerable seem to be adapting to each technological change with ease. The governments are so far behind with tackling these issues that as I’m typing this, it’s borderline irrelevant to even include them while speaking about the crime or potential solutions. Technology is changing too rapidly, and their old, broken systems can’t even dare to keep up. Think of it like the governments’ “War on Drugs.” Drugs won. In this case as well, the governments are not winning. The governments are talking about maybe having a meeting on potentially maybe having legislation around the crimes. The time to have that meeting would have been many years ago. I’m not advocating for governments to legislate our way out of this. I’m on the side of educating and innovating our way out of this.
I have been clear while advocating for the minor survivors of corporate tech platforms that I would not advocate for any solution to the crime that would violate digital privacy rights or erode end-to-end encryption. That has been a personal moral position that I was unwilling to budge on. This is an extremely unpopular and borderline nonexistent position in the anti-human trafficking movement and online child protection space. I’m often fearful that I’m wrong about this. I have always thought that a better pathway forward would have been to incentivize innovation for detection and removal of content. I had no previous exposure to privacy rights activists or Cypherpunks—actually, I came to that conclusion by listening to the voices of MENA region political dissidents and human rights activists. After developing relationships with human rights activists from around the globe, I realized how important privacy rights and encryption are for those who need it most globally. I was simply unwilling to give more power, control, and opportunities for mass surveillance to big abusers like governments wishing to enslave entire nations and untrustworthy corporate tech companies to potentially end some portion of abuses online. On top of all of it, it has been clear to me for years that all potential solutions outside of violating digital privacy rights to detect and remove child sexual exploitation online have not yet been explored aggressively. I’ve been disappointed that there hasn’t been more of a conversation around preventing the crime from happening in the first place.
What has been tried is mass surveillance. In China, they are currently under mass surveillance both online and offline, and their behaviors are attached to a social credit score. Unfortunately, even on state-run and controlled social media platforms, they still have child sexual exploitation and abuse imagery pop up along with other crimes and human rights violations. They also have a thriving black market online due to the oppression from the state. In other words, even an entire loss of freedom and privacy cannot end the sexual exploitation of children online. It’s been tried. There is no reason to repeat this method.
It took me an embarrassingly long time to figure out why I always felt a slight coldness from those in tech and privacy-minded individuals about the topic of child sexual exploitation online. I didn’t have any clue about the “Four Horsemen of the Infocalypse.” This is a term coined by Timothy C. May in 1988. I would have been a child myself when he first said it. I actually laughed at myself when I heard the phrase for the first time. I finally got it. The Cypherpunks weren’t wrong about that topic. They were so spot on that it is borderline uncomfortable. I was mad at first that they knew that early during the birth of the internet that this issue would arise and didn’t address it. Then I got over it because I realized that it wasn’t their job. Their job was—is—to write code. Their job wasn’t to be involved and loving parents or survivor advocates. Their job wasn’t to educate children on internet safety or raise awareness; their job was to write code.
They knew that child sexual abuse material would be shared on the internet. They said what would happen—not in a gleeful way, but a prediction. Then it happened.
I equate it now to a concrete company laying down a road. As you’re pouring the concrete, you can say to yourself, “A terrorist might travel down this road to go kill many, and on the flip side, a beautiful child can be born in an ambulance on this road.” Who or what travels down the road is not their responsibility—they are just supposed to lay the concrete. I’d never go to a concrete pourer and ask them to solve terrorism that travels down roads. Under the current system, law enforcement should stop terrorists before they even make it to the road. The solution to this specific problem is not to treat everyone on the road like a terrorist or to not build the road.
So I understand the perceived coldness from those in tech. Not only was it not their job, but bringing up the topic was seen as the equivalent of asking a free person if they wanted to discuss one of the four topics—child abusers, terrorists, drug dealers, intellectual property pirates, etc.—that would usher in digital authoritarianism for all who are online globally.
Privacy rights advocates and groups have put up a good fight. They stood by their principles. Unfortunately, when it comes to corporate tech, I believe that the issue of privacy is almost a complete lost cause at this point. It’s still worth pushing back, but ultimately, it is a losing battle—a ticking time bomb.
I do think that corporate tech providers could have slowed down the inevitable loss of privacy at the hands of the state by prioritizing the detection and removal of CSAM when they all started online. I believe it would have bought some time, fewer would have been traumatized by that specific crime, and I do believe that it could have slowed down the demand for content. If I think too much about that, I’ll go insane, so I try to push the “if maybes” aside, but never knowing if it could have been handled differently will forever haunt me. At night when it’s quiet, I wonder what I would have done differently if given the opportunity. I’ll probably never know how much corporate tech knew and ignored in the hopes that it would go away while the problem continued to get worse. They had different priorities. The most voiceless and vulnerable exploited on corporate tech never had much of a voice, so corporate tech providers didn’t receive very much pushback.
Now I’m about to say something really wild, and you can call me whatever you want to call me, but I’m going to say what I believe to be true. I believe that the governments are either so incompetent that they allowed the proliferation of CSAM online, or they knowingly allowed the problem to fester long enough to have an excuse to violate privacy rights and erode end-to-end encryption. The US government could have seized the corporate tech providers over CSAM, but I believe that they were so useful as a propaganda arm for the regimes that they allowed them to continue virtually unscathed.
That season is done now, and the governments are making the issue a priority. It will come at a high cost. Privacy on corporate tech providers is virtually done as I’m typing this. It feels like a death rattle. I’m not particularly sure that we had much digital privacy to begin with, but the illusion of a veil of privacy feels gone.
To make matters slightly more complex, it would be hard to convince me that once AI really gets going, digital privacy will exist at all.
I believe that there should be a conversation shift to preserving freedoms and human rights in a post-privacy society.
I don’t want to get locked up because AI predicted a nasty post online from me about the government. I’m not a doomer about AI—I’m just going to roll with it personally. I’m looking forward to the positive changes that will be brought forth by AI. I see it as inevitable. A bit of privacy was helpful while it lasted. Please keep fighting to preserve what is left of privacy either way because I could be wrong about all of this.
On the topic of AI, the addition of AI to the horrific crime of child sexual abuse material and child sexual exploitation in multiple ways so far has been devastating. It’s currently out of control. The genie is out of the bottle. I am hopeful that innovation will get us humans out of this, but I’m not sure how or how long it will take. We must be extremely cautious around AI legislation. It should not be illegal to innovate even if some bad comes with the good. I don’t trust that the governments are equipped to decide the best pathway forward for AI. Source: the entire history of the government.
I have been personally negatively impacted by AI-generated content. Every few days, I get another alert that I’m featured again in what’s called “deep fake pornography” without my consent. I’m not happy about it, but what pains me the most is the thought that for a period of time down the road, many globally will experience what myself and others are experiencing now by being digitally sexually abused in this way. If you have ever had your picture taken and posted online, you are also at risk of being exploited in this way. Your child’s image can be used as well, unfortunately, and this is just the beginning of this particular nightmare. It will move to more realistic interpretations of sexual behaviors as technology improves. I have no brave words of wisdom about how to deal with that emotionally. I do have hope that innovation will save the day around this specific issue. I’m nervous that everyone online will have to ID verify due to this issue. I see that as one possible outcome that could help to prevent one problem but inadvertently cause more problems, especially for those living under authoritarian regimes or anyone who needs to remain anonymous online. A zero-knowledge proof (ZKP) would probably be the best solution to these issues. There are some survivors of violence and/or sexual trauma who need to remain anonymous online for various reasons. There are survivor stories available online of those who have been abused in this way. I’d encourage you seek out and listen to their stories.
There have been periods of time recently where I hesitate to say anything at all because more than likely AI will cover most of my concerns about education, awareness, prevention, detection, and removal of child sexual exploitation online, etc.
Unfortunately, some of the most pressing issues we’ve seen online over the last few years come in the form of “sextortion.” Self-generated child sexual exploitation (SG-CSEM) numbers are continuing to be terrifying. I’d strongly encourage that you look into sextortion data. AI + sextortion is also a huge concern. The perpetrators are using the non-sexually explicit images of children and putting their likeness on AI-generated child sexual exploitation content and extorting money, more imagery, or both from minors online. It’s like a million nightmares wrapped into one. The wild part is that these issues will only get more pervasive because technology is harnessed to perpetuate horror at a scale unimaginable to a human mind.
Even if you banned phones and the internet or tried to prevent children from accessing the internet, it wouldn’t solve it. Child sexual exploitation will still be with us until as a society we start to prevent the crime before it happens. That is the only human way out right now.
There is no reset button on the internet, but if I could go back, I’d tell survivor advocates to heed the warnings of the early internet builders and to start education and awareness campaigns designed to prevent as much online child sexual exploitation as possible. The internet and technology moved quickly, and I don’t believe that society ever really caught up. We live in a world where a child can be groomed by a predator in their own home while sitting on a couch next to their parents watching TV. We weren’t ready as a species to tackle the fast-paced algorithms and dangers online. It happened too quickly for parents to catch up. How can you parent for the ever-changing digital world unless you are constantly aware of the dangers?
I don’t think that the internet is inherently bad. I believe that it can be a powerful tool for freedom and resistance. I’ve spoken a lot about the bad online, but there is beauty as well. We often discuss how victims and survivors are abused online; we rarely discuss the fact that countless survivors around the globe have been able to share their experiences, strength, hope, as well as provide resources to the vulnerable. I do question if giving any government or tech company access to censorship, surveillance, etc., online in the name of serving survivors might not actually impact a portion of survivors negatively. There are a fair amount of survivors with powerful abusers protected by governments and the corporate press. If a survivor cannot speak to the press about their abuse, the only place they can go is online, directly or indirectly through an independent journalist who also risks being censored. This scenario isn’t hard to imagine—it already happened in China. During #MeToo, a survivor in China wanted to post their story. The government censored the post, so the survivor put their story on the blockchain. I’m excited that the survivor was creative and brave, but it’s terrifying to think that we live in a world where that situation is a necessity.
I believe that the future for many survivors sharing their stories globally will be on completely censorship-resistant and decentralized protocols. This thought in particular gives me hope. When we listen to the experiences of a diverse group of survivors, we can start to understand potential solutions to preventing the crimes from happening in the first place.
My heart is broken over the gut-wrenching stories of survivors sexually exploited online. Every time I hear the story of a survivor, I do think to myself quietly, “What could have prevented this from happening in the first place?” My heart is with survivors.
My head, on the other hand, is full of the understanding that the internet should remain free. The free flow of information should not be stopped. My mind is with the innocent citizens around the globe that deserve freedom both online and offline.
The problem is that governments don’t only want to censor illegal content that violates human rights—they create legislation that is so broad that it can impact speech and privacy of all. “Don’t you care about the kids?” Yes, I do. I do so much that I’m invested in finding solutions. I also care about all citizens around the globe that deserve an opportunity to live free from a mass surveillance society. If terrorism happens online, I should not be punished by losing my freedom. If drugs are sold online, I should not be punished. I’m not an abuser, I’m not a terrorist, and I don’t engage in illegal behaviors. I refuse to lose freedom because of others’ bad behaviors online.
I want to be clear that on a long enough timeline, the governments will decide that they can be better parents/caregivers than you can if something isn’t done to stop minors from being sexually exploited online. The price will be a complete loss of anonymity, privacy, free speech, and freedom of religion online. I find it rather insulting that governments think they’re better equipped to raise children than parents and caretakers.
So we can’t go backwards—all that we can do is go forward. Those who want to have freedom will find technology to facilitate their liberation. This will lead many over time to decentralized and open protocols. So as far as I’m concerned, this does solve a few of my worries—those who need, want, and deserve to speak freely online will have the opportunity in most countries—but what about online child sexual exploitation?
When I popped up around the decentralized space, I was met with the fear of censorship. I’m not here to censor you. I don’t write code. I couldn’t censor anyone or any piece of content even if I wanted to across the internet, no matter how depraved. I don’t have the skills to do that.
I’m here to start a conversation. Freedom comes at a cost. You must always fight for and protect your freedom. I can’t speak about protecting yourself from all of the Four Horsemen because I simply don’t know the topics well enough, but I can speak about this one topic.
If there was a shortcut to ending online child sexual exploitation, I would have found it by now. There isn’t one right now. I believe that education is the only pathway forward to preventing the crime of online child sexual exploitation for future generations.
I propose a yearly education course for every child of all school ages, taught as a standard part of the curriculum. Ideally, parents/caregivers would be involved in the education/learning process.
Course: - The creation of the internet and computers - The fight for cryptography - The tech supply chain from the ground up (example: human rights violations in the supply chain) - Corporate tech - Freedom tech - Data privacy - Digital privacy rights - AI (history-current) - Online safety (predators, scams, catfishing, extortion) - Bitcoin - Laws - How to deal with online hate and harassment - Information on who to contact if you are being abused online or offline - Algorithms - How to seek out the truth about news, etc., online
The parents/caregivers, homeschoolers, unschoolers, and those working to create decentralized parallel societies have been an inspiration while writing this, but my hope is that all children would learn this course, even in government ran schools. Ideally, parents would teach this to their own children.
The decentralized space doesn’t want child sexual exploitation to thrive. Here’s the deal: there has to be a strong prevention effort in order to protect the next generation. The internet isn’t going anywhere, predators aren’t going anywhere, and I’m not down to let anyone have the opportunity to prove that there is a need for more government. I don’t believe that the government should act as parents. The governments have had a chance to attempt to stop online child sexual exploitation, and they didn’t do it. Can we try a different pathway forward?
I’d like to put myself out of a job. I don’t want to ever hear another story like John Doe #1 ever again. This will require work. I’ve often called online child sexual exploitation the lynchpin for the internet. It’s time to arm generations of children with knowledge and tools. I can’t do this alone.
Individuals have fought so that I could have freedom online. I want to fight to protect it. I don’t want child predators to give the government any opportunity to take away freedom. Decentralized spaces are as close to a reset as we’ll get with the opportunity to do it right from the start. Start the youth off correctly by preventing potential hazards to the best of your ability.
The good news is anyone can work on this! I’d encourage you to take it and run with it. I added the additional education about the history of the internet to make the course more educational and fun. Instead of cleaning up generations of destroyed lives due to online sexual exploitation, perhaps this could inspire generations of those who will build our futures. Perhaps if the youth is armed with knowledge, they can create more tools to prevent the crime.
This one solution that I’m suggesting can be done on an individual level or on a larger scale. It should be adjusted depending on age, learning style, etc. It should be fun and playful.
This solution does not address abuse in the home or some of the root causes of offline child sexual exploitation. My hope is that it could lead to some survivors experiencing abuse in the home an opportunity to disclose with a trusted adult. The purpose for this solution is to prevent the crime of online child sexual exploitation before it occurs and to arm the youth with the tools to contact safe adults if and when it happens.
In closing, I went to hell a few times so that you didn’t have to. I spoke to the mothers of survivors of minors sexually exploited online—their tears could fill rivers. I’ve spoken with political dissidents who yearned to be free from authoritarian surveillance states. The only balance that I’ve found is freedom online for citizens around the globe and prevention from the dangers of that for the youth. Don’t slow down innovation and freedom. Educate, prepare, adapt, and look for solutions.
I’m not perfect and I’m sure that there are errors in this piece. I hope that you find them and it starts a conversation.

Listen to the full episode here:
<<https://fountain.fm/episode/Ln9Ej0zCZ5dEwfo8w2Ho>>
Bitcoin has always been a narrative revolution disguised as code. White paper, cypherpunk lore, pizza‑day legends - every block is a paragraph in the world’s most relentless epic. But code alone rarely converts the skeptic; it’s the camp‑fire myth that slips past the prefrontal cortex and shakes hands with the limbic system. People don’t adopt protocols first - they fall in love with protagonists.
Early adopters heard the white‑paper hymn, but most folks need characters first: a pizza‑day dreamer; a mother in a small country, crushed by the cost of remittance; a Warsaw street vendor swapping złoty for sats. When their arcs land, the brain releases a neurochemical OP_RETURN which says, “I belong in this plot.” That’s the sly roundabout orange pill: conviction smuggled inside catharsis.
That’s why, from 22–25 May in Warsaw’s Kinoteka, the Bitcoin Film Fest is loading its reels with rebellion. Each documentary, drama, and animated rabbit‑hole is a stealth wallet, zipping conviction straight into the feels of anyone still clasped within the cold claw of fiat. You come for the plot, you leave checking block heights.
Here's the clip of the sermon from the episode:

@ 8d34bd24:414be32b
2025-05-18 20:43:56We are all supposed to share Jesus and His word with those around us. We are called to:
but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence (1 Peter 3:15)
We should daily pray to God, read the Bible, and share Jesus with others. Some Christians will choose to go into full-time service to God. They will be pastors or missionaries. They will work for churches, Christian schools, and other Christian ministries. Of course, not everyone will make serving Jesus a career. That doesn’t mean the non-career Christians have no job to do. We are all to be a light to this world.
There is one ministry, though, that I’d argue is most important: sharing the gospel with and discipling our children.
These words, which I am commanding you today, shall be on your heart. You shall teach them diligently to your sons and shall talk of them when you sit in your house and when you walk by the way and when you lie down and when you rise up. (Deuteronomy 6:6-7)
This passage may have been written in the Old Testament, but I’d argue that it is even more true now that we have the truth of Jesus Christ, “the way, the truth, and the life.” If the Jews were called to diligently teach their kids the law, how much more should Christians diligently teach their kids the wonderous works and words of Jesus?
Train up a child in the way he should go, Even when he is old he will not depart from it. (Proverbs 22:6)
We should be so excited about what Jesus has done for us that it flows out of us in our daily lives. We should have a strong desire to learn God’s word and to share it with others, especially our children. We should share our excitement about Jesus with our kids. We should share our gratefulness for all Jesus has done for us. We should share our excitement about doing God’s work. Our children should see our faith in all we do and say.
Taking our kids to church Sunday morning and to Sunday school or youth group once a week is not going to teach our kids the importance of faith in Jesus. Praying openly at meals, at bedtime, when we hear about someone in need, and when a difficult situation happens teaches our kids to rely on Jesus. Reading our Bibles in front of our kids and doing daily devotions (at whatever time works for you, but we do evenings) teaches them the importance of the Scriptures. Acting according to a Biblical worldview and taking the time to explain to our kids the answers to the hard questions when the culture contradicts the Bible. This may mean taking the time to research answers to your kids’ questions because you don’t know the answer. Being patient with our kids, and even apologizing to them when we fail, teaches them to be humble and to repent. As the old saying goes, “morals are caught more than taught.” Also faith in Jesus is caught more than taught.
We need to live Godly lives that are different than the culture, remembering that our children are always watching, even when they are quite young and can’t articulate what they are learning.
We need to actively teach God’s word. This may be summarizing principles when they are young, but as soon as possible, this should include reading God’s word to our kids. (My daily reading is usually in an NASB Bible, but it is difficult for a young child to understand with its long, complex sentences, so I recommend something like the NLT Bible for children.)
“Now this is the commandment, the statutes and the judgments which the Lord your God has commanded me to teach you, that you might do them in the land where you are going over to possess it, so that you and your son and your grandson might fear the Lord your God, to keep all His statutes and His commandments which I command you, all the days of your life, and that your days may be prolonged. (Deuteronomy 6:1-2) {emphasis mine}
We want to share all of our knowledge of God and the Bible with our kids, grandkids, and great grandkids. We want to disciple our kids into strong faith in God and knowledge of the Bible, so they are capable of training their kids and their grandkids. We want to multiply faith in our families.
It is definitely good to have scheduled, intentional times of training our kids about the Bible. This could be part of homeschooling (which I strongly recommend). This could be family devotions, but we want teaching our kids about God to be just a natural part of life.
You shall teach them to your sons, talking of them when you sit in your house and when you walk along the road and when you lie down and when you rise up. (Deuteronomy 11:19)
Talking about what God has done in our lives, what we have learned about in our personal Bible study, and how the Bible relates to things we see in life should all naturally flow out of our interactions together. Talk about what the Bible says about a subject you hear on the news. Talk about what the Bible says about what is happening in a movie you watch. Talk about what the Bible says about the decisions you and your kids are having to make. Talk about what the Bible says about your kids’ relationship with each other and their friends and parents. God should be a normal part of everything in life.
We also want to make sure our actions don’t drive our kids away from God.
Fathers, do not provoke your children to anger, but bring them up in the discipline and instruction of the Lord. (Ephesians 6:4)
The Bible does not make light of our need to train our kids in faith.
Discipline your son while there is hope, And do not desire his death. (Proverbs 19:18)
This is so important that failure to train up our kids in faith is considered desiring our kid’s death.
God finds this training so critical, He also addresses it from the kid’s point of view and commands them to listen to their parent’s teaching.
My son, give attention to my words;\ Incline your ear to my sayings.\ Do not let them depart from your sight;\ Keep them in the midst of your heart.\ For they are life to those who find them\ And health to all their body.\ Watch over your heart with all diligence,\ For from it flow the springs of life. (Proverbs 4:20-23)
In Proverbs 31, the Bible gives the best explanation of a Godly woman and mother.
She opens her mouth in wisdom,\ And the teaching of kindness is on her tongue.\ She looks well to the ways of her household,\ And does not eat the bread of idleness.\ *Her children rise up and bless her*;\ Her husband also, and he praises her, saying:\ “Many daughters have done nobly,\ But you excel them all.” (Proverbs 31:26-29)
A Mom should continually “open her mouth in wisdom,” and teach kindly. A mother who fulfills this commandment faithfully is promised that “Her children rise up and bless her.” Being loved and appreciated by our kids is a wonderful blessing, but even greater is knowing that we will see our children with us in heaven.
May God guide you and encourage you as you teach, train, and discipline your kids to know their God, Creator, and Savior.
Trust Jesus.

https://www.youtube.com/watch?v=p0Sj1sG05VQ
Here's a great presentation from our good friend nostr:nprofile1qyx8wumn8ghj7cnjvghxjmcpp4mhxue69uhkummn9ekx7mqqyz2hj3zg2g3pqwxuhg69zgjhke4pcmjmmdpnndnefqndgqjt8exwj6ee8v7 , President of The Nakamoto Institute titled Hodl for Good. He gave it earlier this year at the BitBlockBoom Conference, and I think it's something everyone reading this should take 25 minutes to watch. Especially if you find yourself wondering whether or not it's a good idea to spend bitcoin at any given point in time. Michael gives an incredible Austrian Economics 101 lesson on the importance of lowering one's time preference and fully understanding the importance of hodling bitcoin. For the uninitiated, it may seem that the hodl meme is nothing more than a call to hoard bitcoins in hopes of getting rich eventually. However, as Michael points out, there's layers to the hodl meme and the good that hodling can bring individuals and the economy overall.
The first thing one needs to do to better understand the hodl meme is to completely flip the framing that is typically thrust on bitcoiners who encourage others to hodl. Instead of ceding that hodling is a greedy or selfish action, remind people that hodling, or better known as saving, is the foundation of capital formation, from which all productive and efficient economic activity stems. Number go up technology is great and it really matters. It matters because it enables anybody leveraging that technology to accumulate capital that can then be allocated toward productive endeavors that bring value to the individual who creates them and the individual who buys them.
When one internalizes this, it enables them to turn to personal praxis and focus on minimizing present consumption while thinking of ways to maximize long-term value creation. Live below your means, stack sats, and use the time that you're buying to think about things that you want in the future. By lowering your time preference and saving in a harder money you will have the luxury of demanding higher quality goods in the future. Another way of saying this is that you will be able to reshape production by voting with your sats. Initially when you hold them off the market by saving them - signaling that the market doesn't have goods worthy of your sats - and ultimately by redeploying them into the market when you find higher quality goods that meet the standards desire.
The first part of this equation is extremely important because it sends a signal to producers that they need to increase the quality of their work. As more and more individuals decide to use bitcoin as their savings technology, the signal gets stronger. And over many cycles we should begin to see low quality cheap goods exit the market in favor of higher quality goods that provide more value and lasts longer and, therefore, make it easier for an individual to depart with their hard-earned and hard-saved sats. This is only but one aspect that Michael tries to imbue throughout his presentation.
The other is the ability to buy yourself leisure time when you lower your time preference and save more than you spend. When your savings hit a critical tipping point that gives you the luxury to sit back and experience true leisure, which Michael explains is not idleness, but the contemplative space to study, create art, refine taste, and to find what "better goods" actually are. Those who can experience true leisure while reaping the benefits of saving in a hard asset that is increasing in purchasing power significantly over the long term are those who build truly great things. Things that outlast those who build them. Great art, great monuments, great institutions were all built by men who were afforded the time to experience leisure. Partly because they were leveraging hard money as their savings and the place they stored the profits reaped from their entrepreneurial endeavors.
If you squint and look into the future a couple of decades, it isn't hard to see a reality like this manifesting. As more people begin to save in Bitcoin, the forces of supply and demand will continue to come into play. There will only ever be 21 million bitcoin, there are around 8 billion people on this planet, and as more of those 8 billion individuals decide that bitcoin is the best savings vehicle, the price of bitcoin will rise.
When the price of bitcoin rises, it makes all other goods cheaper in bitcoin terms and, again, expands the entrepreneurial opportunity. The best part about this feedback loop is that even non-holders of bitcoin benefit through higher real wages and faster tech diffusion. The individuals and business owners who decide to hodl bitcoin will bring these benefits to the world whether you decide to use bitcoin or not.
This is why it is virtuous to hodl bitcoin. The potential for good things to manifest throughout the world increase when more individuals decide to hodl bitcoin. And as Michael very eloquently points out, this does not mean that people will not spend their bitcoin. It simply means that they have standards for the things that they will spend their bitcoin on. And those standards are higher than most who are fully engrossed in the high velocity trash economy have today.
In my opinion, one of those higher causes worthy of a sats donation is nostr:nprofile1qyfhwumn8ghj7enjv4jhyetvv9uju7re0gq3uamnwvaz7tmfdemxjmrvv9nk2tt0w468v6tvd3skwefwvdhk6qpqwzc9lz2f40azl98shkjewx3pywg5e5alwqxg09ew2mdyeey0c2rqcfecft . Consider donating so they can preserve and disseminate vital information about bitcoin and its foundations.
The Shell Game: How Health Narratives May Distract from Vaccine Risks
In our recent podcast, Dr. Jack Kruse presented a concerning theory about public health messaging. He argues that figures like Casey and Callie Means are promoting food and exercise narratives as a deliberate distraction from urgent vaccine issues. While no one disputes healthy eating matters, Dr. Kruse insists that focusing on "Froot Loops and Red Dye" diverts attention from what he sees as immediate dangers of mRNA vaccines, particularly for children.
"It's gonna take you 50 years to die from processed food. But the messenger jab can drop you like Damar Hamlin." - Dr Jack Kruse
Dr. Kruse emphasized that approximately 25,000 children per month are still receiving COVID vaccines despite concerns, with 3 million doses administered since Trump's election. This "shell game," as he describes it, allows vaccines to remain on childhood schedules while public attention fixates on less immediate health threats. As host, I believe this pattern deserves our heightened scrutiny given the potential stakes for our children's wellbeing.

2025-05-16 18:40:18Die zwei mächtigsten Krieger sind Geduld und Zeit. \ Leo Tolstoi
Zum Wohle unserer Gesundheit, unserer Leistungsfähigkeit und letztlich unseres Glücks ist es wichtig, die eigene Energie bewusst zu pflegen. Das gilt umso mehr für an gesellschaftlichen Themen interessierte, selbstbewusste und kritisch denkende Menschen. Denn für deren Wahrnehmung und Wohlbefinden waren und sind die rasanten, krisen- und propagandagefüllten letzten Jahre in Absurdistan eine harte Probe.
Nur wer regelmäßig Kraft tankt und Wege findet, mit den Herausforderungen umzugehen, kann eine solche Tortur überstehen, emotionale Erschöpfung vermeiden und trotz allem zufrieden sein. Dazu müssen wir erkunden, was uns Energie gibt und was sie uns raubt. Durch Selbstreflexion und Achtsamkeit finden wir sicher Dinge, die uns erfreuen und inspirieren, und andere, die uns eher stressen und belasten.
Die eigene Energie ist eng mit unserer körperlichen und mentalen Gesundheit verbunden. Methoden zur Förderung der körperlichen Gesundheit sind gut bekannt: eine ausgewogene Ernährung, regelmäßige Bewegung sowie ausreichend Schlaf und Erholung. Bei der nicht minder wichtigen emotionalen Balance wird es schon etwas komplizierter. Stress abzubauen, die eigenen Grenzen zu kennen oder solche zum Schutz zu setzen sowie die Konzentration auf Positives und Sinnvolles wären Ansätze.
Der emotionale ist auch der Bereich, über den «Energie-Räuber» bevorzugt attackieren. Das sind zum Beispiel Dinge wie Überforderung, Perfektionismus oder mangelhafte Kommunikation. Social Media gehören ganz sicher auch dazu. Sie stehlen uns nicht nur Zeit, sondern sind höchst manipulativ und erhöhen laut einer aktuellen Studie das Risiko für psychische Probleme wie Angstzustände und Depressionen.
Geben wir negativen oder gar bösen Menschen keine Macht über uns. Das Dauerfeuer der letzten Jahre mit Krisen, Konflikten und Gefahren sollte man zwar kennen, darf sich aber davon nicht runterziehen lassen. Das Ziel derartiger konzertierter Aktionen ist vor allem, unsere innere Stabilität zu zerstören, denn dann sind wir leichter zu steuern. Aber Geduld: Selbst vermeintliche «Sonnenköniginnen» wie EU-Kommissionspräsidentin von der Leyen fallen, wenn die Zeit reif ist.
Es ist wichtig, dass wir unsere ganz eigenen Bedürfnisse und Werte erkennen. Unsere Energiequellen müssen wir identifizieren und aktiv nutzen. Dazu gehören soziale Kontakte genauso wie zum Beispiel Hobbys und Leidenschaften. Umgeben wir uns mit Sinnhaftigkeit und lassen wir uns nicht die Energie rauben!
Mein Wahlspruch ist schon lange: «Was die Menschen wirklich bewegt, ist die Kultur.» Jetzt im Frühjahr beginnt hier in Andalusien die Zeit der «Ferias», jener traditionellen Volksfeste, die vor Lebensfreude sprudeln. Konzentrieren wir uns auf die schönen Dinge und auf unsere eigenen Talente – soziale Verbundenheit wird helfen, unsere innere Kraft zu stärken und zu bewahren.

2025-05-18 16:24:01First, the caveat: Yes, I understand that there's a consistent libertarian case for free trade as a policy position.
With all the discourse around tariffs, I wanted to highlight something of a moral oddity in the arguments being used by many free trade libertarians (I am a free trade libertarian, btw): namely, the idea that we (Americans) should happily take advantage of subsidized exports from poorer countries.
I do agree with the economics of the argument: By subsidizing exports, other countries are imposing a deadweight loss on themselves and passing savings along to US consumers.
Why are libertarians celebrating this, though? Poor, oppressed foreigners are being stolen from by their authoritarian governments and American consumers are benefiting from it financially. Thinking this is a good situation is odd and thinking you have a right to take part in it is even stranger.
Libertarians certainly understand that subsidies are wrong and economically harmful, and that they benefit a select group of politically connected cronies. Nothing about that changes just because it's happening in a foreign country and your grocery bill benefits from it.
Saying "That's how they run their country. It's none of our business." is a plea to moral relativism, which libertarians generally avoid. Libertarians also usually understand that the "they" who rule is not the same as the "they" who are ruled. Is it just too uncomfortable to acknowledge being the beneficiary of abuse?
I can't help but draw parallels to the abolitionists of two hundred years ago, who refused to buy the products of slaves. I think they're mostly viewed as having been "on the right side of history", but they're probably on the "wrong" side of most "free trade" arguments. Another of those arguments being that it doesn't help the poor oppressed foreigner to stop doing business with their oppressor (yes, many lefties get all mixed up about who the oppressors are).
Anyway, I have no brilliant conclusion to offer. What do you all think?

2025-05-20 01:35:20**Ascolta bene! ** A man's sentimental longing, though often disguised in noble language and imagination, is a sickness—not a virtue.
It begins as a slight inclination toward tenderness, cloaked in sweetness. Then it reveals itself as a masked addiction: a constant need to be seen by a woman, validated by her, and reciprocated—as if someone else's affection were the only anchor preventing the shipwreck of his emotions.
The man who understands the weight of leadership seeks no applause, no gratitude, not even romantic love. He knows that his role is not theatrical but structural. He is not measured by the emotion he evokes, but by the stability he ensures. Being a true man is not ornamental. He is not a decorative symbol in the family frame.
We live in an era where male roles have been distorted by an overindulgence in emotion. The man stopped guiding and began asking for direction. His firmness was exchanged for softness, his decisiveness for hesitation. Trying to please, many have given up authority. Trying to love, they’ve begun to bow. A man who begs for validation within his own home is not a leader—he is a guest. And when the patriarch has to ask for a seat at the table he should preside over and sustain, something has already been irreversibly inverted.
Unexamined longing turns into pleading. And all begging is the antechamber of humiliation. A man who never learned to cultivate dignified solitude will inevitably fall to his knees in desperation. And then, he yields. Yields to mediocre presence, to shallow affection, to constant disrespect. He smiles while he bleeds, praises the one who despises him, accepts crumbs and pretends it’s a banquet. All of it, cazzo... just to avoid the horror of being alone.
Davvero, amico mio, for the men who beg for romance, only the consolation of being remembered will remain—not with respect, but with pity and disgust.
The modern world feeds the fragile with illusions, but reality spits them out. Sentimental longing is now celebrated as sensitivity. But every man who nurtures it as an excuse will, sooner or later, pay for it with his dignity.
Thank you for reading, my friend!

2025-03-18 14:43:08Warning: This piece contains a conversation about difficult topics. Please proceed with caution.
TL;DR please educate your children about online safety.
Julian Assange wrote in his 2012 book Cypherpunks, “This book is not a manifesto. There isn’t time for that. This book is a warning.” I read it a few times over the past summer. Those opening lines definitely stood out to me. I wish we had listened back then. He saw something about the internet that few had the ability to see. There are some individuals who are so close to a topic that when they speak, it’s difficult for others who aren’t steeped in it to visualize what they’re talking about. I didn’t read the book until more recently. If I had read it when it came out, it probably would have sounded like an unknown foreign language to me. Today it makes more sense.
This isn’t a manifesto. This isn’t a book. There is no time for that. It’s a warning and a possible solution from a desperate and determined survivor advocate who has been pulling and unraveling a thread for a few years. At times, I feel too close to this topic to make any sense trying to convey my pathway to my conclusions or thoughts to the general public. My hope is that if nothing else, I can convey my sense of urgency while writing this. This piece is a watchman’s warning.
When a child steps online, they are walking into a new world. A new reality. When you hand a child the internet, you are handing them possibilities—good, bad, and ugly. This is a conversation about lowering the potential of negative outcomes of stepping into that new world and how I came to these conclusions. I constantly compare the internet to the road. You wouldn’t let a young child run out into the road with no guidance or safety precautions. When you hand a child the internet without any type of guidance or safety measures, you are allowing them to play in rush hour, oncoming traffic. “Look left, look right for cars before crossing.” We almost all have been taught that as children. What are we taught as humans about safety before stepping into a completely different reality like the internet? Very little.
I could never really figure out why many folks in tech, privacy rights activists, and hackers seemed so cold to me while talking about online child sexual exploitation. I always figured that as a survivor advocate for those affected by these crimes, that specific, skilled group of individuals would be very welcoming and easy to talk to about such serious topics. I actually had one hacker laugh in my face when I brought it up while I was looking for answers. I thought maybe this individual thought I was accusing them of something I wasn’t, so I felt bad for asking. I was constantly extremely disappointed and would ask myself, “Why don’t they care? What could I say to make them care more? What could I say to make them understand the crisis and the level of suffering that happens as a result of the problem?”
I have been serving minor survivors of online child sexual exploitation for years. My first case serving a survivor of this specific crime was in 2018—a 13-year-old girl sexually exploited by a serial predator on Snapchat. That was my first glimpse into this side of the internet. I won a national award for serving the minor survivors of Twitter in 2023, but I had been working on that specific project for a few years. I was nominated by a lawyer representing two survivors in a legal battle against the platform. I’ve never really spoken about this before, but at the time it was a choice for me between fighting Snapchat or Twitter. I chose Twitter—or rather, Twitter chose me. I heard about the story of John Doe #1 and John Doe #2, and I was so unbelievably broken over it that I went to war for multiple years. I was and still am royally pissed about that case. As far as I was concerned, the John Doe #1 case proved that whatever was going on with corporate tech social media was so out of control that I didn’t have time to wait, so I got to work. It was reading the messages that John Doe #1 sent to Twitter begging them to remove his sexual exploitation that broke me. He was a child begging adults to do something. A passion for justice and protecting kids makes you do wild things. I was desperate to find answers about what happened and searched for solutions. In the end, the platform Twitter was purchased. During the acquisition, I just asked Mr. Musk nicely to prioritize the issue of detection and removal of child sexual exploitation without violating digital privacy rights or eroding end-to-end encryption. Elon thanked me multiple times during the acquisition, made some changes, and I was thanked by others on the survivors’ side as well.
I still feel that even with the progress made, I really just scratched the surface with Twitter, now X. I left that passion project when I did for a few reasons. I wanted to give new leadership time to tackle the issue. Elon Musk made big promises that I knew would take a while to fulfill, but mostly I had been watching global legislation transpire around the issue, and frankly, the governments are willing to go much further with X and the rest of corporate tech than I ever would. My work begging Twitter to make changes with easier reporting of content, detection, and removal of child sexual exploitation material—without violating privacy rights or eroding end-to-end encryption—and advocating for the minor survivors of the platform went as far as my principles would have allowed. I’m grateful for that experience. I was still left with a nagging question: “How did things get so bad with Twitter where the John Doe #1 and John Doe #2 case was able to happen in the first place?” I decided to keep looking for answers. I decided to keep pulling the thread.
I never worked for Twitter. This is often confusing for folks. I will say that despite being disappointed in the platform’s leadership at times, I loved Twitter. I saw and still see its value. I definitely love the survivors of the platform, but I also loved the platform. I was a champion of the platform’s ability to give folks from virtually around the globe an opportunity to speak and be heard.
I want to be clear that John Doe #1 really is my why. He is the inspiration. I am writing this because of him. He represents so many globally, and I’m still inspired by his bravery. One child’s voice begging adults to do something—I’m an adult, I heard him. I’d go to war a thousand more lifetimes for that young man, and I don’t even know his name. Fighting has been personally dark at times; I’m not even going to try to sugarcoat it, but it has been worth it.
The data surrounding the very real crime of online child sexual exploitation is available to the public online at any time for anyone to see. I’d encourage you to go look at the data for yourself. I believe in encouraging folks to check multiple sources so that you understand the full picture. If you are uncomfortable just searching around the internet for information about this topic, use the terms “CSAM,” “CSEM,” “SG-CSEM,” or “AI Generated CSAM.” The numbers don’t lie—it’s a nightmare that’s out of control. It’s a big business. The demand is high, and unfortunately, business is booming. Organizations collect the data, tech companies often post their data, governments report frequently, and the corporate press has covered a decent portion of the conversation, so I’m sure you can find a source that you trust.
Technology is changing rapidly, which is great for innovation as a whole but horrible for the crime of online child sexual exploitation. Those wishing to exploit the vulnerable seem to be adapting to each technological change with ease. The governments are so far behind with tackling these issues that as I’m typing this, it’s borderline irrelevant to even include them while speaking about the crime or potential solutions. Technology is changing too rapidly, and their old, broken systems can’t even dare to keep up. Think of it like the governments’ “War on Drugs.” Drugs won. In this case as well, the governments are not winning. The governments are talking about maybe having a meeting on potentially maybe having legislation around the crimes. The time to have that meeting would have been many years ago. I’m not advocating for governments to legislate our way out of this. I’m on the side of educating and innovating our way out of this.
I have been clear while advocating for the minor survivors of corporate tech platforms that I would not advocate for any solution to the crime that would violate digital privacy rights or erode end-to-end encryption. That has been a personal moral position that I was unwilling to budge on. This is an extremely unpopular and borderline nonexistent position in the anti-human trafficking movement and online child protection space. I’m often fearful that I’m wrong about this. I have always thought that a better pathway forward would have been to incentivize innovation for detection and removal of content. I had no previous exposure to privacy rights activists or Cypherpunks—actually, I came to that conclusion by listening to the voices of MENA region political dissidents and human rights activists. After developing relationships with human rights activists from around the globe, I realized how important privacy rights and encryption are for those who need it most globally. I was simply unwilling to give more power, control, and opportunities for mass surveillance to big abusers like governments wishing to enslave entire nations and untrustworthy corporate tech companies to potentially end some portion of abuses online. On top of all of it, it has been clear to me for years that all potential solutions outside of violating digital privacy rights to detect and remove child sexual exploitation online have not yet been explored aggressively. I’ve been disappointed that there hasn’t been more of a conversation around preventing the crime from happening in the first place.
What has been tried is mass surveillance. In China, they are currently under mass surveillance both online and offline, and their behaviors are attached to a social credit score. Unfortunately, even on state-run and controlled social media platforms, they still have child sexual exploitation and abuse imagery pop up along with other crimes and human rights violations. They also have a thriving black market online due to the oppression from the state. In other words, even an entire loss of freedom and privacy cannot end the sexual exploitation of children online. It’s been tried. There is no reason to repeat this method.
It took me an embarrassingly long time to figure out why I always felt a slight coldness from those in tech and privacy-minded individuals about the topic of child sexual exploitation online. I didn’t have any clue about the “Four Horsemen of the Infocalypse.” This is a term coined by Timothy C. May in 1988. I would have been a child myself when he first said it. I actually laughed at myself when I heard the phrase for the first time. I finally got it. The Cypherpunks weren’t wrong about that topic. They were so spot on that it is borderline uncomfortable. I was mad at first that they knew that early during the birth of the internet that this issue would arise and didn’t address it. Then I got over it because I realized that it wasn’t their job. Their job was—is—to write code. Their job wasn’t to be involved and loving parents or survivor advocates. Their job wasn’t to educate children on internet safety or raise awareness; their job was to write code.
They knew that child sexual abuse material would be shared on the internet. They said what would happen—not in a gleeful way, but a prediction. Then it happened.
I equate it now to a concrete company laying down a road. As you’re pouring the concrete, you can say to yourself, “A terrorist might travel down this road to go kill many, and on the flip side, a beautiful child can be born in an ambulance on this road.” Who or what travels down the road is not their responsibility—they are just supposed to lay the concrete. I’d never go to a concrete pourer and ask them to solve terrorism that travels down roads. Under the current system, law enforcement should stop terrorists before they even make it to the road. The solution to this specific problem is not to treat everyone on the road like a terrorist or to not build the road.
So I understand the perceived coldness from those in tech. Not only was it not their job, but bringing up the topic was seen as the equivalent of asking a free person if they wanted to discuss one of the four topics—child abusers, terrorists, drug dealers, intellectual property pirates, etc.—that would usher in digital authoritarianism for all who are online globally.
Privacy rights advocates and groups have put up a good fight. They stood by their principles. Unfortunately, when it comes to corporate tech, I believe that the issue of privacy is almost a complete lost cause at this point. It’s still worth pushing back, but ultimately, it is a losing battle—a ticking time bomb.
I do think that corporate tech providers could have slowed down the inevitable loss of privacy at the hands of the state by prioritizing the detection and removal of CSAM when they all started online. I believe it would have bought some time, fewer would have been traumatized by that specific crime, and I do believe that it could have slowed down the demand for content. If I think too much about that, I’ll go insane, so I try to push the “if maybes” aside, but never knowing if it could have been handled differently will forever haunt me. At night when it’s quiet, I wonder what I would have done differently if given the opportunity. I’ll probably never know how much corporate tech knew and ignored in the hopes that it would go away while the problem continued to get worse. They had different priorities. The most voiceless and vulnerable exploited on corporate tech never had much of a voice, so corporate tech providers didn’t receive very much pushback.
Now I’m about to say something really wild, and you can call me whatever you want to call me, but I’m going to say what I believe to be true. I believe that the governments are either so incompetent that they allowed the proliferation of CSAM online, or they knowingly allowed the problem to fester long enough to have an excuse to violate privacy rights and erode end-to-end encryption. The US government could have seized the corporate tech providers over CSAM, but I believe that they were so useful as a propaganda arm for the regimes that they allowed them to continue virtually unscathed.
That season is done now, and the governments are making the issue a priority. It will come at a high cost. Privacy on corporate tech providers is virtually done as I’m typing this. It feels like a death rattle. I’m not particularly sure that we had much digital privacy to begin with, but the illusion of a veil of privacy feels gone.
To make matters slightly more complex, it would be hard to convince me that once AI really gets going, digital privacy will exist at all.
I believe that there should be a conversation shift to preserving freedoms and human rights in a post-privacy society.
I don’t want to get locked up because AI predicted a nasty post online from me about the government. I’m not a doomer about AI—I’m just going to roll with it personally. I’m looking forward to the positive changes that will be brought forth by AI. I see it as inevitable. A bit of privacy was helpful while it lasted. Please keep fighting to preserve what is left of privacy either way because I could be wrong about all of this.
On the topic of AI, the addition of AI to the horrific crime of child sexual abuse material and child sexual exploitation in multiple ways so far has been devastating. It’s currently out of control. The genie is out of the bottle. I am hopeful that innovation will get us humans out of this, but I’m not sure how or how long it will take. We must be extremely cautious around AI legislation. It should not be illegal to innovate even if some bad comes with the good. I don’t trust that the governments are equipped to decide the best pathway forward for AI. Source: the entire history of the government.
I have been personally negatively impacted by AI-generated content. Every few days, I get another alert that I’m featured again in what’s called “deep fake pornography” without my consent. I’m not happy about it, but what pains me the most is the thought that for a period of time down the road, many globally will experience what myself and others are experiencing now by being digitally sexually abused in this way. If you have ever had your picture taken and posted online, you are also at risk of being exploited in this way. Your child’s image can be used as well, unfortunately, and this is just the beginning of this particular nightmare. It will move to more realistic interpretations of sexual behaviors as technology improves. I have no brave words of wisdom about how to deal with that emotionally. I do have hope that innovation will save the day around this specific issue. I’m nervous that everyone online will have to ID verify due to this issue. I see that as one possible outcome that could help to prevent one problem but inadvertently cause more problems, especially for those living under authoritarian regimes or anyone who needs to remain anonymous online. A zero-knowledge proof (ZKP) would probably be the best solution to these issues. There are some survivors of violence and/or sexual trauma who need to remain anonymous online for various reasons. There are survivor stories available online of those who have been abused in this way. I’d encourage you seek out and listen to their stories.
There have been periods of time recently where I hesitate to say anything at all because more than likely AI will cover most of my concerns about education, awareness, prevention, detection, and removal of child sexual exploitation online, etc.
Unfortunately, some of the most pressing issues we’ve seen online over the last few years come in the form of “sextortion.” Self-generated child sexual exploitation (SG-CSEM) numbers are continuing to be terrifying. I’d strongly encourage that you look into sextortion data. AI + sextortion is also a huge concern. The perpetrators are using the non-sexually explicit images of children and putting their likeness on AI-generated child sexual exploitation content and extorting money, more imagery, or both from minors online. It’s like a million nightmares wrapped into one. The wild part is that these issues will only get more pervasive because technology is harnessed to perpetuate horror at a scale unimaginable to a human mind.
Even if you banned phones and the internet or tried to prevent children from accessing the internet, it wouldn’t solve it. Child sexual exploitation will still be with us until as a society we start to prevent the crime before it happens. That is the only human way out right now.
There is no reset button on the internet, but if I could go back, I’d tell survivor advocates to heed the warnings of the early internet builders and to start education and awareness campaigns designed to prevent as much online child sexual exploitation as possible. The internet and technology moved quickly, and I don’t believe that society ever really caught up. We live in a world where a child can be groomed by a predator in their own home while sitting on a couch next to their parents watching TV. We weren’t ready as a species to tackle the fast-paced algorithms and dangers online. It happened too quickly for parents to catch up. How can you parent for the ever-changing digital world unless you are constantly aware of the dangers?
I don’t think that the internet is inherently bad. I believe that it can be a powerful tool for freedom and resistance. I’ve spoken a lot about the bad online, but there is beauty as well. We often discuss how victims and survivors are abused online; we rarely discuss the fact that countless survivors around the globe have been able to share their experiences, strength, hope, as well as provide resources to the vulnerable. I do question if giving any government or tech company access to censorship, surveillance, etc., online in the name of serving survivors might not actually impact a portion of survivors negatively. There are a fair amount of survivors with powerful abusers protected by governments and the corporate press. If a survivor cannot speak to the press about their abuse, the only place they can go is online, directly or indirectly through an independent journalist who also risks being censored. This scenario isn’t hard to imagine—it already happened in China. During #MeToo, a survivor in China wanted to post their story. The government censored the post, so the survivor put their story on the blockchain. I’m excited that the survivor was creative and brave, but it’s terrifying to think that we live in a world where that situation is a necessity.
I believe that the future for many survivors sharing their stories globally will be on completely censorship-resistant and decentralized protocols. This thought in particular gives me hope. When we listen to the experiences of a diverse group of survivors, we can start to understand potential solutions to preventing the crimes from happening in the first place.
My heart is broken over the gut-wrenching stories of survivors sexually exploited online. Every time I hear the story of a survivor, I do think to myself quietly, “What could have prevented this from happening in the first place?” My heart is with survivors.
My head, on the other hand, is full of the understanding that the internet should remain free. The free flow of information should not be stopped. My mind is with the innocent citizens around the globe that deserve freedom both online and offline.
The problem is that governments don’t only want to censor illegal content that violates human rights—they create legislation that is so broad that it can impact speech and privacy of all. “Don’t you care about the kids?” Yes, I do. I do so much that I’m invested in finding solutions. I also care about all citizens around the globe that deserve an opportunity to live free from a mass surveillance society. If terrorism happens online, I should not be punished by losing my freedom. If drugs are sold online, I should not be punished. I’m not an abuser, I’m not a terrorist, and I don’t engage in illegal behaviors. I refuse to lose freedom because of others’ bad behaviors online.
I want to be clear that on a long enough timeline, the governments will decide that they can be better parents/caregivers than you can if something isn’t done to stop minors from being sexually exploited online. The price will be a complete loss of anonymity, privacy, free speech, and freedom of religion online. I find it rather insulting that governments think they’re better equipped to raise children than parents and caretakers.
So we can’t go backwards—all that we can do is go forward. Those who want to have freedom will find technology to facilitate their liberation. This will lead many over time to decentralized and open protocols. So as far as I’m concerned, this does solve a few of my worries—those who need, want, and deserve to speak freely online will have the opportunity in most countries—but what about online child sexual exploitation?
When I popped up around the decentralized space, I was met with the fear of censorship. I’m not here to censor you. I don’t write code. I couldn’t censor anyone or any piece of content even if I wanted to across the internet, no matter how depraved. I don’t have the skills to do that.
I’m here to start a conversation. Freedom comes at a cost. You must always fight for and protect your freedom. I can’t speak about protecting yourself from all of the Four Horsemen because I simply don’t know the topics well enough, but I can speak about this one topic.
If there was a shortcut to ending online child sexual exploitation, I would have found it by now. There isn’t one right now. I believe that education is the only pathway forward to preventing the crime of online child sexual exploitation for future generations.
I propose a yearly education course for every child of all school ages, taught as a standard part of the curriculum. Ideally, parents/caregivers would be involved in the education/learning process.
Course: - The creation of the internet and computers - The fight for cryptography - The tech supply chain from the ground up (example: human rights violations in the supply chain) - Corporate tech - Freedom tech - Data privacy - Digital privacy rights - AI (history-current) - Online safety (predators, scams, catfishing, extortion) - Bitcoin - Laws - How to deal with online hate and harassment - Information on who to contact if you are being abused online or offline - Algorithms - How to seek out the truth about news, etc., online
The parents/caregivers, homeschoolers, unschoolers, and those working to create decentralized parallel societies have been an inspiration while writing this, but my hope is that all children would learn this course, even in government ran schools. Ideally, parents would teach this to their own children.
The decentralized space doesn’t want child sexual exploitation to thrive. Here’s the deal: there has to be a strong prevention effort in order to protect the next generation. The internet isn’t going anywhere, predators aren’t going anywhere, and I’m not down to let anyone have the opportunity to prove that there is a need for more government. I don’t believe that the government should act as parents. The governments have had a chance to attempt to stop online child sexual exploitation, and they didn’t do it. Can we try a different pathway forward?
I’d like to put myself out of a job. I don’t want to ever hear another story like John Doe #1 ever again. This will require work. I’ve often called online child sexual exploitation the lynchpin for the internet. It’s time to arm generations of children with knowledge and tools. I can’t do this alone.
Individuals have fought so that I could have freedom online. I want to fight to protect it. I don’t want child predators to give the government any opportunity to take away freedom. Decentralized spaces are as close to a reset as we’ll get with the opportunity to do it right from the start. Start the youth off correctly by preventing potential hazards to the best of your ability.
The good news is anyone can work on this! I’d encourage you to take it and run with it. I added the additional education about the history of the internet to make the course more educational and fun. Instead of cleaning up generations of destroyed lives due to online sexual exploitation, perhaps this could inspire generations of those who will build our futures. Perhaps if the youth is armed with knowledge, they can create more tools to prevent the crime.
This one solution that I’m suggesting can be done on an individual level or on a larger scale. It should be adjusted depending on age, learning style, etc. It should be fun and playful.
This solution does not address abuse in the home or some of the root causes of offline child sexual exploitation. My hope is that it could lead to some survivors experiencing abuse in the home an opportunity to disclose with a trusted adult. The purpose for this solution is to prevent the crime of online child sexual exploitation before it occurs and to arm the youth with the tools to contact safe adults if and when it happens.
In closing, I went to hell a few times so that you didn’t have to. I spoke to the mothers of survivors of minors sexually exploited online—their tears could fill rivers. I’ve spoken with political dissidents who yearned to be free from authoritarian surveillance states. The only balance that I’ve found is freedom online for citizens around the globe and prevention from the dangers of that for the youth. Don’t slow down innovation and freedom. Educate, prepare, adapt, and look for solutions.
I’m not perfect and I’m sure that there are errors in this piece. I hope that you find them and it starts a conversation.

2025-05-16 18:06:46Bitcoin has always been rooted in freedom and resistance to authority. I get that many of you are conflicted about the US Government stacking but by design we cannot stop anyone from using bitcoin. Many have asked me for my thoughts on the matter, so let’s rip it.
Concern
One of the most glaring issues with the strategic bitcoin reserve is its foundation, built on stolen bitcoin. For those of us who value private property this is an obvious betrayal of our core principles. Rather than proof of work, the bitcoin that seeds this reserve has been taken by force. The US Government should return the bitcoin stolen from Bitfinex and the Silk Road.
Using stolen bitcoin for the reserve creates a perverse incentive. If governments see bitcoin as a valuable asset, they will ramp up efforts to confiscate more bitcoin. The precedent is a major concern, and I stand strongly against it, but it should be also noted that governments were already seizing coin before the reserve so this is not really a change in policy.
Ideally all seized bitcoin should be burned, by law. This would align incentives properly and make it less likely for the government to actively increase coin seizures. Due to the truly scarce properties of bitcoin, all burned bitcoin helps existing holders through increased purchasing power regardless. This change would be unlikely but those of us in policy circles should push for it regardless. It would be best case scenario for American bitcoiners and would create a strong foundation for the next century of American leadership.
Optimism
The entire point of bitcoin is that we can spend or save it without permission. That said, it is a massive benefit to not have one of the strongest governments in human history actively trying to ruin our lives.
Since the beginning, bitcoiners have faced horrible regulatory trends. KYC, surveillance, and legal cases have made using bitcoin and building bitcoin businesses incredibly difficult. It is incredibly important to note that over the past year that trend has reversed for the first time in a decade. A strategic bitcoin reserve is a key driver of this shift. By holding bitcoin, the strongest government in the world has signaled that it is not just a fringe technology but rather truly valuable, legitimate, and worth stacking.
This alignment of incentives changes everything. The US Government stacking proves bitcoin’s worth. The resulting purchasing power appreciation helps all of us who are holding coin and as bitcoin succeeds our government receives direct benefit. A beautiful positive feedback loop.
Realism
We are trending in the right direction. A strategic bitcoin reserve is a sign that the state sees bitcoin as an asset worth embracing rather than destroying. That said, there is a lot of work left to be done. We cannot be lulled into complacency, the time to push forward is now, and we cannot take our foot off the gas. We have a seat at the table for the first time ever. Let's make it worth it.
We must protect the right to free usage of bitcoin and other digital technologies. Freedom in the digital age must be taken and defended, through both technical and political avenues. Multiple privacy focused developers are facing long jail sentences for building tools that protect our freedom. These cases are not just legal battles. They are attacks on the soul of bitcoin. We need to rally behind them, fight for their freedom, and ensure the ethos of bitcoin survives this new era of government interest. The strategic reserve is a step in the right direction, but it is up to us to hold the line and shape the future.

2025-05-18 14:42:48What do we mean when we talk about "fitness"? The word implies a connection to a higher purpose: "Fitness for what?"
Biologically, "fitness" refers to the propensity of an organism to pass on it's genes. Biological fitness is clearly context dependent: i.e. an anaconda isn't so fit if it gets moved to the arctic. I think we can build on that, while making it more human.
I think of fitness as our capacity to thrive in our environment. That's going to be different for each of us, depending on our environment and our preferences. However, there are some useful implications of thinking of fitness this way: 1. Chores, errands, work, play, and family activities might be the best kind of exercise, since they are physical activities that are directly tied to your lifestyle. 2. Supplemental exercise should be geared towards your lifestyle and improving your ability to accomplish things you need to be able to do. 3. There's no such thing as a universal "best exercise" or "best diet", because we all have different fitness objectives. 4. "Fitness" is not static: We do different things and have different priorities at different points in our lives, so our fitness goals should change over time. Many of us will even have seasonal fitness changes, since we don't do the same things in winter as we do in summer.
How do you all think about "fitness"?
Is it a highfalutin ivory tower concept or is it just ABs?

2025-05-16 17:59:23Recently we have seen a wave of high profile X accounts hacked. These attacks have exposed the fragility of the status quo security model used by modern social media platforms like X. Many users have asked if nostr fixes this, so lets dive in. How do these types of attacks translate into the world of nostr apps? For clarity, I will use X’s security model as representative of most big tech social platforms and compare it to nostr.
The Status Quo
On X, you never have full control of your account. Ultimately to use it requires permission from the company. They can suspend your account or limit your distribution. Theoretically they can even post from your account at will. An X account is tied to an email and password. Users can also opt into two factor authentication, which adds an extra layer of protection, a login code generated by an app. In theory, this setup works well, but it places a heavy burden on users. You need to create a strong, unique password and safeguard it. You also need to ensure your email account and phone number remain secure, as attackers can exploit these to reset your credentials and take over your account. Even if you do everything responsibly, there is another weak link in X infrastructure itself. The platform’s infrastructure allows accounts to be reset through its backend. This could happen maliciously by an employee or through an external attacker who compromises X’s backend. When an account is compromised, the legitimate user often gets locked out, unable to post or regain control without contacting X’s support team. That process can be slow, frustrating, and sometimes fruitless if support denies the request or cannot verify your identity. Often times support will require users to provide identification info in order to regain access, which represents a privacy risk. The centralized nature of X means you are ultimately at the mercy of the company’s systems and staff.
Nostr Requires Responsibility
Nostr flips this model radically. Users do not need permission from a company to access their account, they can generate as many accounts as they want, and cannot be easily censored. The key tradeoff here is that users have to take complete responsibility for their security. Instead of relying on a username, password, and corporate servers, nostr uses a private key as the sole credential for your account. Users generate this key and it is their responsibility to keep it safe. As long as you have your key, you can post. If someone else gets it, they can post too. It is that simple. This design has strong implications. Unlike X, there is no backend reset option. If your key is compromised or lost, there is no customer support to call. In a compromise scenario, both you and the attacker can post from the account simultaneously. Neither can lock the other out, since nostr relays simply accept whatever is signed with a valid key.
The benefit? No reliance on proprietary corporate infrastructure.. The negative? Security rests entirely on how well you protect your key.
Future Nostr Security Improvements
For many users, nostr’s standard security model, storing a private key on a phone with an encrypted cloud backup, will likely be sufficient. It is simple and reasonably secure. That said, nostr’s strength lies in its flexibility as an open protocol. Users will be able to choose between a range of security models, balancing convenience and protection based on need.
One promising option is a web of trust model for key rotation. Imagine pre-selecting a group of trusted friends. If your account is compromised, these people could collectively sign an event announcing the compromise to the network and designate a new key as your legitimate one. Apps could handle this process seamlessly in the background, notifying followers of the switch without much user interaction. This could become a popular choice for average users, but it is not without tradeoffs. It requires trust in your chosen web of trust, which might not suit power users or large organizations. It also has the issue that some apps may not recognize the key rotation properly and followers might get confused about which account is “real.”
For those needing higher security, there is the option of multisig using FROST (Flexible Round-Optimized Schnorr Threshold). In this setup, multiple keys must sign off on every action, including posting and updating a profile. A hacker with just one key could not do anything. This is likely overkill for most users due to complexity and inconvenience, but it could be a game changer for large organizations, companies, and governments. Imagine the White House nostr account requiring signatures from multiple people before a post goes live, that would be much more secure than the status quo big tech model.
Another option are hardware signers, similar to bitcoin hardware wallets. Private keys are kept on secure, offline devices, separate from the internet connected phone or computer you use to broadcast events. This drastically reduces the risk of remote hacks, as private keys never touches the internet. It can be used in combination with multisig setups for extra protection. This setup is much less convenient and probably overkill for most but could be ideal for governments, companies, or other high profile accounts.
Nostr’s security model is not perfect but is robust and versatile. Ultimately users are in control and security is their responsibility. Apps will give users multiple options to choose from and users will choose what best fits their need.

2025-03-15 23:00:40I want to see Nostr succeed. If you can think of a way I can help make that happen, I’m open to it. I’d like your suggestions.
My schedule’s shifting soon, and I could volunteer a few hours a week to a Nostr project. I won’t have more total time, but how I use it will change.
Why help? I care about freedom. Nostr’s one of the most powerful freedom tools I’ve seen in my lifetime. If I believe that, I should act on it.
I don’t care about money or sats. I’m not rich, I don’t have extra cash. That doesn’t drive me—freedom does. I’m volunteering, not asking for pay.
I’m not here for clout. I’ve had enough spotlight in my life; it doesn’t move me. If I wanted clout, I’d be on Twitter dropping basic takes. Clout’s easy. Freedom’s hard. I’d rather help anonymously. No speaking at events—small meetups are cool for the vibe, but big conferences? Not my thing. I’ll never hit a huge Bitcoin conference. It’s just not my scene.
That said, I could be convinced to step up if it’d really boost Nostr—as long as it’s legal and gets results.
In this space, I’d watch for social engineering. I watch out for it. I’m not here to make friends, just to help. No shade—you all seem great—but I’ve got a full life and awesome friends irl. I don’t need your crew or to be online cool. Connect anonymously if you want; I’d encourage it.
I’m sick of watching other social media alternatives grow while Nostr kinda stalls. I could trash-talk, but I’d rather do something useful.
Skills? I’m good at spotting social media problems and finding possible solutions. I won’t overhype myself—that’s weird—but if you’re responding, you probably see something in me. Perhaps you see something that I don’t see in myself.
If you need help now or later with Nostr projects, reach out. Nostr only—nothing else. Anonymous contact’s fine. Even just a suggestion on how I can pitch in, no project attached, works too. 💜
Creeps or harassment will get blocked or I’ll nuke my simplex code if it becomes a problem.
https://simplex.chat/contact#/?v=2-4&smp=smp%3A%2F%2FSkIkI6EPd2D63F4xFKfHk7I1UGZVNn6k1QWZ5rcyr6w%3D%40smp9.simplex.im%2FbI99B3KuYduH8jDr9ZwyhcSxm2UuR7j0%23%2F%3Fv%3D1-2%26dh%3DMCowBQYDK2VuAyEAS9C-zPzqW41PKySfPCEizcXb1QCus6AyDkTTjfyMIRM%253D%26srv%3Djssqzccmrcws6bhmn77vgmhfjmhwlyr3u7puw4erkyoosywgl67slqqd.onion

2025-05-16 17:51:54In much of the world, it is incredibly difficult to access U.S. dollars. Local currencies are often poorly managed and riddled with corruption. Billions of people demand a more reliable alternative. While the dollar has its own issues of corruption and mismanagement, it is widely regarded as superior to the fiat currencies it competes with globally. As a result, Tether has found massive success providing low cost, low friction access to dollars. Tether claims 400 million total users, is on track to add 200 million more this year, processes 8.1 million transactions daily, and facilitates $29 billion in daily transfers. Furthermore, their estimates suggest nearly 40% of users rely on it as a savings tool rather than just a transactional currency.
Tether’s rise has made the company a financial juggernaut. Last year alone, Tether raked in over $13 billion in profit, with a lean team of less than 100 employees. Their business model is elegantly simple: hold U.S. Treasuries and collect the interest. With over $113 billion in Treasuries, Tether has turned a straightforward concept into a profit machine.
Tether’s success has resulted in many competitors eager to claim a piece of the pie. This has triggered a massive venture capital grift cycle in USD tokens, with countless projects vying to dethrone Tether. Due to Tether’s entrenched network effect, these challengers face an uphill battle with little realistic chance of success. Most educated participants in the space likely recognize this reality but seem content to perpetuate the grift, hoping to cash out by dumping their equity positions on unsuspecting buyers before they realize the reality of the situation.
Historically, Tether’s greatest vulnerability has been U.S. government intervention. For over a decade, the company operated offshore with few allies in the U.S. establishment, making it a major target for regulatory action. That dynamic has shifted recently and Tether has seized the opportunity. By actively courting U.S. government support, Tether has fortified their position. This strategic move will likely cement their status as the dominant USD token for years to come.
While undeniably a great tool for the millions of users that rely on it, Tether is not without flaws. As a centralized, trusted third party, it holds the power to freeze or seize funds at its discretion. Corporate mismanagement or deliberate malpractice could also lead to massive losses at scale. In their goal of mitigating regulatory risk, Tether has deepened ties with law enforcement, mirroring some of the concerns of potential central bank digital currencies. In practice, Tether operates as a corporate CBDC alternative, collaborating with authorities to surveil and seize funds. The company proudly touts partnerships with leading surveillance firms and its own data reveals cooperation in over 1,000 law enforcement cases, with more than $2.5 billion in funds frozen.
The global demand for Tether is undeniable and the company’s profitability reflects its unrivaled success. Tether is owned and operated by bitcoiners and will likely continue to push forward strategic goals that help the movement as a whole. Recent efforts to mitigate the threat of U.S. government enforcement will likely solidify their network effect and stifle meaningful adoption of rival USD tokens or CBDCs. Yet, for all their achievements, Tether is simply a worse form of money than bitcoin. Tether requires trust in a centralized entity, while bitcoin can be saved or spent without permission. Furthermore, Tether is tied to the value of the US Dollar which is designed to lose purchasing power over time, while bitcoin, as a truly scarce asset, is designed to increase in purchasing power with adoption. As people awaken to the risks of Tether’s control, and the benefits bitcoin provides, bitcoin adoption will likely surpass it.

2025-05-20 01:22:31พอพูดถึงบริษัทอย่าง Formo ที่ทำชีสโดยไม่ใช้วัวเลย คนส่วนใหญ่จะนึกถึงคำว่า “นวัตกรรม” “ยั่งยืน” “ลดโลกร้อน” กันเป็นด่านแรก แต่พอเฮียมองทะลุม่านควันพวกนี้ไป จะเห็นทุนรายใหญ่ที่หนุนหลังอยู่ ซึ่งหลายเจ้าก็ไม่ใช่ผู้พิทักษ์โลก แต่เป็นผู้เล่นตัวจี๊ดในอุตสาหกรรมอาหารโลกมายาวนาน
หนึ่งในนั้นคือบริษัทจากเกาหลีใต้ชื่อ CJ CheilJedang ซึ่งอาจฟังดูไกลตัว แต่จริงๆ แล้ว เฮียว่าชื่อนี้โผล่ตามซองอาหารสำเร็จรูปในครัวคนไทยหลายบ้านโดยไม่รู้ตัว
ถ้าจะเข้าใจ Formo ให้ถึงแก่น เราต้องมองไปถึงทุนที่ “ใส่เงิน” และ “ใส่จุดยืน” ลงไปในบริษัทนั้น และหนึ่งในผู้ถือหุ้นรายสำคัญก็คือ CJ CheilJedang บริษัทเกาหลีใต้ที่ก่อตั้งมาตั้งแต่ปี 1953 โดยเริ่มจากการเป็นโรงงานผลิตน้ำตาล จากนั้นก็กินรวบแทบทุกวงจรอาหารของเกาหลี
โปรไฟล์ CJ แค่เห็นภาพรวมก็ขนลุกแล้วครับ ลูกพี่เราแข็งแกร่งขนาดไหน - เป็นเจ้าของแบรนด์ Bibigo ที่เราอาจจะคุ้นในสินค้า กิมจิ และ CJ Foods ที่มีขายทั่วโลก -เป็นผู้ผลิต กรดอะมิโน รายใหญ่ของโลก เช่น ไลซีน, ทรีโอนีน, ทริปโตแฟน ที่ใช้เป็นวัตถุดิบในอาหารสัตว์ แต่ตอนนี้หลายบริษัทเอาไปใส่ใน Plant-based food แล้วเคลมว่าเป็นโปรตีนสมบูรณ์ -เป็นเจ้าของโรงงานผลิต แบคทีเรียสายพันธุ์พิเศษ สำหรับการหมักหลายประเภท -ขึ้นชื่อเรื่อง bioscience โดยเฉพาะ precision fermentation ซึ่งเป็นเทคโนโลยีเดียวกับที่ Formo ใช้ผลิตเคซีน (โปรตีนในนมวัว)
แปลว่า CJ ไม่ได้มาลงทุนใน Formo แบบ “หวังผลกำไรเฉยๆ” แต่เขามองเห็น “อนาคตใหม่ของอาหาร” ที่ตัวเองจะเป็นเจ้าของต้นน้ำยันปลายน้ำ
คำถามก็คือเบื้องลึกการลงทุนใน Formo ใครได้อะไร? Formo ปิดรอบระดมทุน Series A ได้ประมาณ 50 ล้านดอลลาร์สหรัฐ เมื่อปี 2021 โดยมีนักลงทุนหลายเจ้า เช่น EQT Ventures, Elevat3 Capital, Atomico แต่ CJ CheilJedang ก็เป็นหนึ่งในผู้ลงทุนเชิงกลยุทธ์ (strategic investor) ที่เข้ามาแบบไม่ใช่แค่ลงเงิน แต่เอา เทคโนโลยี + เครือข่ายโรงงาน + ซัพพลายเชนระดับโลก มาเสริมให้ Formo ขยายได้เร็วขึ้น
การจับมือกันครั้งนี้มีนัยยะสำคัญครับ -Formo ได้ เทคโนโลยีหมักจุลินทรีย์ (ที่ CJ ถนัดมาก) และช่องทางกระจายสินค้าในเอเชีย -CJ ได้ ถือหุ้นในบริษัทที่กำลังจะเปลี่ยนภาพ “ผลิตภัณฑ์จากนม” ให้กลายเป็นสิ่งที่ไม่ต้องมีสัตว์อีกต่อไป ซึ่งจะเป็นกลยุทธ์สำคัญในการสร้างแบรนด์อาหารแห่งอนาคต ที่นมจะต้องมาจากโรงงานผลิตเท่านั้นจึงจะมีคุณสมบัติที่ดีทั้งสารอาหารและความสะอาด
CJ เองก็เคยประกาศต่อสื่อว่า อยากเป็น “Global Lifestyle Company” ซึ่งฟังดูเบาๆ แต่จริงๆ คือแผนใหญ่ในการ เปลี่ยนวิธีการกินของคนทั้งโลกได้เลยเช่นกัน -จาก “อาหารจริง” ไปเป็น “อาหารสังเคราะห์” (synthetic food) -จาก “ฟาร์มสัตว์” ไปเป็น “ถังหมักจุลินทรีย์” -จาก “ความหลากหลายตามธรรมชาติ” ไปเป็น “สูตรกลาง” ที่ควบคุมได้ในระดับโมเลกุล
การหนุนหลัง Formo จึงไม่ใช่เรื่องบังเอิญ แต่เป็นอีกหนึ่งหมากในกระดานใหญ่ที่ CJ วางไว้ เพื่อเป็นเจ้าของอาหารอนาคตแบบไม่ต้องเลี้ยงหมู ไก่ วัว แต่ครองเทคโนโลยีแทน
คำถามคือแล้วผู้บริโภคจะรู้ทันไหมว่า เบื้องหลังชีสที่ไม่มีวัว อาจมี “ทุนที่อยากครองโลกอาหาร” คำที่เคลมว่า “ยั่งยืน” อาจสร้างระบบอาหารใหม่ที่ยิ่งห่างจากธรรมชาติเข้าไปทุกที
คนที่เคย “กลัวสารเคมี” ในอาหารแปรรูป กลับกลืนผลิตภัณฑ์จากห้องแล็บ โดยคิดว่า “มันคือความสะอาดและอนาคต” #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

2025-03-09 22:36:26Não são recentes as táticas da esquerda de tentar reprimir intelectualmente seus opositores na base do deboche, da ironia, do desprezo e do boicote à credibilidade. Até Marx usava ironia para chamar os críticos de "burgueses iludidos". A diferença é que, no século XXI, trocaram o manifesto comunista por threads no Twitter e a dialética por memes de mau gosto.
A Falácia da Superioridade Moral
O debate sobre o "pobre de direita" no Brasil é contaminado por uma premissa tácita da esquerda: a ideia de que classes baixas só podem ter consciência política se aderirem a pautas progressistas. Quem ousa divergir é tratado como "traidor de classe", "manipulado", "ignorante", ou até vítimas de deboches como alguma pessoa com um qi em temperatura ambiente repetir diversas vezes "não é possível que ainda exista pobre de direita", "nunca vou entender pobre de direita", ou "pobre de direita é muito burro, rico eu até entendo", como se o autor dessas frases fosse o paladino dos mais oprimidos e pobres. Esse discurso, porém, não resiste a uma análise empírica, histórica ou sociológica.
Contexto Histórico: A Esquerda e o Mito do "Voto Consciente"
A noção de que o pobre deve votar na esquerda por "interesse de classe" é herança do marxismo ortodoxo, que via a política como mero reflexo da posição econômica. No entanto, a realidade é mais complexa:
- Dados do Latinobarómetro (2022): 41% dos brasileiros de baixa renda (até 2 salários mínimos) apoiam redução de impostos e maior liberdade econômica — pautas tradicionalmente associadas à direita.
- Pesquisa IPEC (2023): 58% dos pobres brasileiros priorizam "segurança pública" como principal demanda, acima de "distribuição de renda".
Esses números não são acidentais. Refletem uma mudança estrutural: o pobre moderno não é mais o "operário industrial" do século XX, mas um empreendedor informal, motorista de app, ou microempresário — figuras que valorizam autonomia e rejeitam paternalismo estatal. Eles dizem não entender o pobre de direita e que nunca vai entendê-los, mas o fato é que não entendem porque nunca conversaram com um sem fazer cara de psicólogo de posto de saúde. Sua "preocupação" é só uma máscara para esconder o desprezo por quem ousa pensar diferente do seu manual de "oprimido ideal".
Se ainda não entenderam:
Direita ≠ rico: Tem gente que trabalha 12h/dia e vota em liberal porque quer ser dono do próprio negócio, não pra pagar mais taxação pra você postar meme no Twitter.
Acham que são o Sherlock Holmes da pobreza: o palpite de que "o pobre é manipulado" é tão raso quanto sua compreensão de economia básica.
A Psicologia por Trás do Voto Conservador nas Periferias
A esquerda atribui o voto pobre em direita a "falta de educação" ou "manipulação midiática". Essa tese é não apenas elitista, mas cientificamente falsa:
Análise Psicológica Básica (para você que se acha o Paulo Freire):
- Síndrome do Branco Salvador: Acha que o pobre é uma criatura tão frágil que precisa de você pra pensar. Spoiler: ele não precisa.
- Viés da Superioridade Moral: "Se você é pobre e não concorda comigo, você é burro". Parabéns, recriou a escravidão intelectual.
- Efeito Dunning-Kruger: Não sabe o que é CLT, mas dá palpite sobre reforma trabalhista.- Estudo da Universidade de São Paulo (USP, 2021): Entre moradores de favelas, 63% associam políticas de segurança dura (como "bandido bom é bandido morto") à proteção de seus negócios e famílias. Para eles, a esquerda é "branda demais" com o crime.
- Pesquisa FGV (2020): 71% dos trabalhadores informais rejeitam aumentos de impostos, mesmo que para financiar programas sociais. Motivo: já sofrem com a burocracia estatal para legalizar seus negócios.
Esses dados revelam uma racionalidade prática: o pobre avalia políticas pelo impacto imediato em sua vida, não por abstrações ideológicas. Enquanto a esquerda fala em "reforma estrutural" e tenta importar discursos estrangeiros para debate, por exemplo, o tema irrelevante do pronome neutro, ele quer resolver problemas como:
- Violência (que afeta seu comércio);
- Impostos (que consomem até 40% do lucro de um camelô);
- Burocracia (que impede a legalização de sua barraca de pastel).
Religião, Valores e a Hipocrisia do "Ateísmo de Redes Sociais"
A esquerda subestima o papel da religião na formação política das classes baixas. No Brasil, 76% dos evangélicos são pobres (Datafolha, 2023), e suas igrejas promovem valores como:
- Família tradicional (contra pautas progressistas como ideologia de gênero em escolas);
- Auto-responsabilidade (ênfase em "trabalho duro" em vez de assistencialismo).Exemplo Concreto:
Nas favelas de São Paulo, pastores evangélicos são frequentemente eleitos a cargos locais com plataformas anticrime e pró-mercado. Para seus eleitores, a esquerda urbana (que defende descriminalização de drogas e críticas à polícia) representa uma ameaça ao seu estilo de vida.
A Esquerda e seu Desprezo pela Autonomia do Pobre
O cerne do debate é a incapacidade da esquerda de aceitar que o pobre possa ser autônomo. Algumas evidências:
O Caso dos Empreendedores Informais
- Segundo o IBGE (2023), 40% dos trabalhadores brasileiros estão na informalidade. Muitos veem o Estado como obstáculo, não aliado. Políticas de direita (como simplificação tributária) são mais atraentes para eles que o Bolsa Família.
A Ascensão do Conservadorismo Periférico
- Pessoas assim tem um pensamento simples. Sua mensagem: "Queremos empreender, não depender de político."
A Rejeição ao "Vitimismo"
- Pesquisa Atlas Intel (2022): 68% dos pobres brasileiros rejeitam o termo "vítima da sociedade". Preferem ser vistos como "lutadores".
A projeção freudiana "o pobre é burro porque eu sou inteligente"
O deboche esquerdista esconde um complexo de inferioridade disfarçado de superioridade moral. É a Síndrome do Salvador em sua forma mais patética:
- Passo 1: Assume-se que o pobre é um ser desprovido de agência.
- Passo 2: Qualquer desvio da narrativa é atribuído a "manipulação da elite".
- Passo 3: Quem critica o processo é chamado de "fascista".Exemplo Prático:
Quando uma empregada doméstica diz que prefere o livre mercado a programas sociais, a esquerda não pergunta "por quê?" — ela grita "lavagem cerebral!". A ironia? Essa mesma esquerda defende a autonomia feminina, exceto quando a mulher é pobre e pensa diferente.Dados Globais: O Fenômeno Não é Brasileiro
A ideia de que "pobre de direita" é uma anomalia é desmentida por evidências internacionais:
- Estados Unidos: 38% dos eleitores com renda abaixo de US$ 30k/ano votaram em Trump em 2020 (Pew Research). Motivos principais: conservadorismo social e rejeição a impostos. A esquerda: "vítimas da falsa consciência". Mais um detalhe: na última eleição de 2024, grande parte da classe "artística" milionária dos Estados Unidos, figuras conhecidas, promoveram em peso a Kamala Harris, do Partido Democrata. Percebe como a esquerda atual é a personificaçãoda burguesia e de só pensar na própria barriga?
- Argentina: Javier Milei, libertário radical, quando candidato, tinha forte apoio nas villas miseria (favelas). Seu lema — "O estado é um parasita" — ressoa entre quem sofria com inflação de 211% ao ano.
- Índia: O partido BJP (direita nacionalista) domina entre os pobres rurais, que associam a esquerda a elites urbanas desconectadas de suas necessidades.
A história que a esquerda tenta apagar: pobres de direita existem desde sempre
A esquerda age como se o "pobre de direita" fosse uma invenção recente do MBL, mas a realidade é que classes baixas conservadoras são regra, não exceção, na história mundial:
- Revolução Francesa (1789): Camponeses apoiaram a monarquia contra os jacobinos urbanos que queriam "libertá-los".
- Brasil Imperial: Escravos libertos que viraram pequenos proprietários rurais rejeitavam o abolicionismo radical — queriam integração, não utopia.Tradução:
Quando o pobre não segue o script, a esquerda inventa teorias conspiratórias.
A Hipocrisia da Esquerda Urbana e Universitária
Enquanto acusa o pobre de direita de "alienado", a esquerda brasileira é dominada por uma elite desconectada da realidade periférica:
- Perfil Socioeconômico: 82% dos filiados ao PSOL têm ensino superior completo (TSE, 2023). Apenas 6% moram em bairros periféricos.
- Prioridades Descoladas: Enquanto o pobre debate segurança e custo de vida, a esquerda pauta discussões como "linguagem não-binária em editais públicos" — tema irrelevante para quem luta contra o desemprego. Os grandes teóricos comunistas se reviram no túmulo quando veem o que a esquerda se tornou: não debatem os reais problemas do Brasil, e sim sobre suas próprias emoções.
"A esquerda brasileira trocou o operário pelo influencer progressista. O pobre virou um personagem de campanha, não um interlocutor real."
A diversidade de pensamento que a esquerda não suporta
A esquerda prega diversidade — desde que você seja diverso dentro de um checklist pré-aprovado. Pobre LGBTQ+? Herói. Pobre evangélico? Fascista. Pobre que abre MEI? "Peão do capitalismo". A realidade é que favelas e periferias são microcosmos de pluralidade ideológica, algo que assusta quem quer reduzir seres humanos a estereótipos.
Respostas aos Argumentos Esquerdistas (e Por que Falham)
"O pobre de direita é manipulado pela mídia!"
- Contradição: Se a mídia tradicional é dominada por elites (como alegam), por que grandes veículos são abertamente progressistas? A Record (evangélica) é exceção, não regra.
Contradição Central:
Como explicar que, segundo o Banco Mundial (2023), países com maior liberdade econômica (ex.: Chile, Polônia) reduziram a pobreza extrema em 60% nas últimas décadas, enquanto modelos estatizantes (ex.: Venezuela, Argentina com o governo peronista) afundaram na miséria? Simples: a esquerda prefere culpar o "neoliberalismo" a admitir que o pobre com o mínimo de consciência quer emprego, não esmola.Dado que Machuca:
- 71% das mulheres da periferia rejeitam o feminismo radical, associando-o a "prioridades distantes da realidade" (Instituto Locomotiva, 2023)."Ele vota contra os próprios interesses!"
- Falácia: Pressupõe que a esquerda define o que é o "interesse do pobre". Para um pai de família na Cidade de Deus, ter a boca de fogo fechada pode ser mais urgente que um aumento de 10% no Bolsa Família.
O pobre de direita não é uma anomalia. É o produto natural de um mundo complexo onde seres humanos têm aspirações, medos e valores diversos. Enquanto a esquerda insiste em tratá-lo como um projeto fracassado, ele está ocupado:
- Trabalhando para não depender do governo.
- Escolhendo religiões que dão sentido à sua vida.
- Rejeitando pautas identitárias que não resolvem o custo do gás de cozinha."É falta de educação política!"
- Ironia: Nos países nórdicos (modelo da esquerda), as classes baixas são as mais conservadoras. Educação não correlaciona com progressismo.
Por que o Debuste Precisa Acabar
A insistência em descredibilizar o pobre de direita revela um projeto de poder fracassado. A esquerda, ao substituir diálogo por deboche, perdeu a capacidade de representar quem mais precisaria dela. Enquanto isso, a direita — nem sempre por virtude, mas por pragmatismo — capturou o descontentamento de milhões com o status quo.
O pobre de direita existe porque ele não precisa da permissão do rico de esquerda para pensar. A incapacidade de entender isso só prova que a esquerda é a nova aristocracia.
Último Dado: Nas eleições de 2022, Tarcísio de Freitas (direita) venceu em 72% das favelas de São Paulo. O motivo? Seu discurso anti-burocracia e pró-microempreendedor.
A mensagem é clara: o pobre não é um projeto ideológico. É um agente político autônomo — e quem não entender isso continuará perdendo eleições.
A esquerda elitista não odeia o pobre de direita por ele ser "irracional". Odeia porque ele desafia o monopólio moral que ela construiu sobre a miséria alheia. Enquanto isso, o pobre segue sua vida, ignorando os berros de quem acha que sabem mais da sua vida que ele mesmo.
Pergunta Retórica (Para Incomodar):
Se a esquerda é tão sábia, por que não usa essa sabedoria para entender que pobre também cansa de ser tratado como cachorro que late no ritmo errado?

2025-05-16 17:12:05One of the most common criticisms leveled against nostr is the perceived lack of assurance when it comes to data storage. Critics argue that without a centralized authority guaranteeing that all data is preserved, important information will be lost. They also claim that running a relay will become prohibitively expensive. While there is truth to these concerns, they miss the mark. The genius of nostr lies in its flexibility, resilience, and the way it harnesses human incentives to ensure data availability in practice.
A nostr relay is simply a server that holds cryptographically verifiable signed data and makes it available to others. Relays are simple, flexible, open, and require no permission to run. Critics are right that operating a relay attempting to store all nostr data will be costly. What they miss is that most will not run all encompassing archive relays. Nostr does not rely on massive archive relays. Instead, anyone can run a relay and choose to store whatever subset of data they want. This keeps costs low and operations flexible, making relay operation accessible to all sorts of individuals and entities with varying use cases.
Critics are correct that there is no ironclad guarantee that every piece of data will always be available. Unlike bitcoin where data permanence is baked into the system at a steep cost, nostr does not promise that every random note or meme will be preserved forever. That said, in practice, any data perceived as valuable by someone will likely be stored and distributed by multiple entities. If something matters to someone, they will keep a signed copy.
Nostr is the Streisand Effect in protocol form. The Streisand effect is when an attempt to suppress information backfires, causing it to spread even further. With nostr, anyone can broadcast signed data, anyone can store it, and anyone can distribute it. Try to censor something important? Good luck. The moment it catches attention, it will be stored on relays across the globe, copied, and shared by those who find it worth keeping. Data deemed important will be replicated across servers by individuals acting in their own interest.
Nostr’s distributed nature ensures that the system does not rely on a single point of failure or a corporate overlord. Instead, it leans on the collective will of its users. The result is a network where costs stay manageable, participation is open to all, and valuable verifiable data is stored and distributed forever.

2025-05-16 07:51:08Payjoin allows the sender and receiver of an on-chain payment to collaborate and create a transaction that breaks on-chain heuristics, allowing a more private transaction with ambiguous payment amount and UTXO ownership. Additionally, it can also be used for UTXO consolidation (receiver saves future fees) and batching payments (receiver can make payment(s) of their own in the process of receiving one), also known as transaction cut-through. Other than improved privacy, the rest of the benefits are typically applicable to the receiver, not the sender.
BIP-78 was the original payjoin protocol that required the receiver to run a endpoint/server (always online) in order to mediate the payjoin process. Payjoin adoption has remained pretty low, something attributed to the server & perpetual online-ness requirement. This is the motivation for payjoin v2.
The purpose of the one-pager is to analyse the protocol, and highlight the UX issues or tradeoffs it entails, so that the payjoin user flows can be appropriately designed and the tradeoffs likewise communicated. A further document on UX solutions might be needed to identify solutions and opportunities
The following observations are generally limited to individual users transacting through their mobile devices:
While users naturally want better privacy and fee-savings, they also want to minimise friction and minimise (optimise) payment time. These are universal and more immediate needs since they deal with the user experience.
Added manual steps
TL;DR v2 payjoin eliminates server & simultaneous user-liveness requirements (increasing TAM, and opportunities to payjoin, as a result) by adding manual steps.
Usually, the extent of the receiver's involvement in the transaction process is limited to sharing their address with the sender. Once they share the address/URI, they can basically forget about it. In the target scenario for v2 payjoin, the receiver must come online again (except they have no way of knowing "when") to contribute input(s) and sign the PSBT. This can be unexpected, unintuitive and a bit of a hassle.
Usually (and even with payjoin v1), the sender crafts and broadcasts the transaction in one go; meaning the user's job is done within a few seconds/minutes. With payjoin v2, they must share the original-PSBT with the receiver, and then wait for them to do their part. Once the the receiver has done that, the sender must come online to review the transaction, sign it & broadcast.
In summary,
In payjoin v1, step 3 is automated and instant, so delay 2, 3 =~ 0. As the user experiences it, the process is completed in a single session, akin to a non-payjoin transaction.
With payjoin v2, Steps 2 & 3 in the above diagram are widely spread and noticeable. These manual steps are separated by uncertain delays (more on that below) when compared to a non-payjoin transaction.
Delays
We've established that both senders and receivers must take extra manual steps to execute a payoin transaction. With payjoin v2, this process gets split into multiple sessions, since the sender and receiver are not like to be online simultaneously.
Delay 2 & 3 (see diagram above) are uncertain in nature. Most users do not open their bitcoin wallets for days or weeks! The receiver must come online before the timeout hits in order for the payjoin process to work, otherwise time is just wasted with no benefit. UX or technical solutions are needed to minimise these delays.
Delays might be exacerbated if the setup is based on hardware wallet and/or uses multisig.
Notifications or background processes
There is one major problem when we say "the user must come online to..." but in reality the user has no way of knowing there is a payjoin PSBT waiting for them. After a PSBT is sent to the relay, the opposite user would only find out about it whenever they happen to come online. Notifications and background sync processes might be necessary to minimise delays. This is absolutely essential to avert timeouts in addition to saving valuable time. Another risk is phantom payjoin stuff after the timeout is expired if receiver-side does not know it has.
Fee Savings
The following observations might be generally applicable for both original and this v2 payjoin version. Fee-savings with payjoin is a tricky topic. Of course, overall a payjoin transaction is always cheaper than 2 separate transactions, since they get to share the overhead.
Additionally, without the receiver contributing to fees, the chosen fee rate of the PSBT (at the beginning) drops, and can lead to slower confirmation. From another perspective, a sender paying with payjoin pays higher fees for similar confirmation target. This has been observed in a production wallet years back. Given that total transaction time can extend to days, the fee environment itself might change, and all this must be considered when designing the UX.
Of course, there is nothing stopping the receiver from contributing to fees, but this idea is likely entirely novel to the bitcoin ecosystem (perhaps payments ecosystem in general) and the user base. Additionally, nominally it involves the user paying fees and tolerating delays just to receive bitcoin. Without explicit incentives/features that encourage receivers to participate, payjoining might seem like an unncessary hassle.
Overall, it seems that payjoin makes UX significant tradeoffs for important privacy (and potential fee-saving) benefits. This means that the UX might have to do significant heavy-lifting, to ensure that users are not surprised, confused or frustrated when they try to transact on-chain in a privacy-friendly feature. Good, timely communication, new features for consolidation & txn-cutthrough and guided user flows seem crucial to ensure payjoin adoption and for help make on-chain privacy a reality for users.

2025-03-06 06:00:53De acordo com a Forbes, a Ripple (Empresa responsável pela Criptomoeda XRP) tem financiado e apoiado campanhas contra a mineração de Bitcoin.
Por que Ripple faz propaganda anti-bitcoin?
Simples: eles são o oposto do Bitcoin em quase tudo. Enquanto o Bitcoin foi criado para ser descentralizado, resistente à censura e independente de instituições, o Ripple é basicamente um serviço bancário 2.0. Eles precisam atacar o Bitcoin para justificar sua própria existência.
O que você não sabe:
- Ripple Labs controla a maioria do XRP: Eles têm um estoque estratégico que pode ser liberado no mercado a qualquer momento. Isso é o oposto de descentralização.
- XRP não é uma moeda para "pessoas comuns": Foi criada para bancos e instituições financeiras. Basicamente, é o "banco central" das criptomoedas.
- Ripple não é blockchain no sentido tradicional: Eles usam um protocolo chamado Ripple Protocol Consensus Algorithm (RPCA), que é mais rápido, mas menos descentralizado.
Os principais ataques do Ripple ao Bitcoin:
- Anti-mineração: O Ripple critica o consumo de energia do Bitcoin, mas esquece que seu próprio sistema depende de servidores centralizados que também consomem energia.
- Anti-reserva estratégica: O Ripple tem um estoque gigante de XRP, mas critica o Bitcoin por ser "deflacionário". Hipocrisia? Nunca ouvi falar.
- Anti-descentralização: O Ripple prega que a descentralização do Bitcoin é "ineficiente", mas o que eles realmente querem é manter o controle nas mãos de poucos.
Análise Psicológica Básica (para você que acha que XRP é o futuro):
- Síndrome do Underdog: Acha que apoiar o Ripple te faz um rebelde, mas na verdade você está torcendo para o sistema bancário tradicional.
- Viés de Confirmação: Só ouve opiniões que validam sua decisão de comprar XRP.
- Efeito Dunning-Kruger: Acha que entender Ripple te torna um especialista em criptomoedas, mas não sabe o que é um hard fork.
Estudo de Caso (Real, mas Você Vai Ignorar):
Carlos, 30 anos, comprou XRP porque "é o futuro das transações bancárias". Ele não sabe que o Ripple está sendo processado pela SEC por vender XRP como um título não registrado. Carlos agora está esperando o "pump" que nunca vem.Conclusão: ou, "volte para a aula de economia do ensino médio"
Ripple não é o futuro das finanças. É só mais um player tentando lucrar em um mercado competitivo. E sua propaganda anti-Bitcoin? Essa só prova que a descentralização assusta quem quer controle. Agora vá estudar blockchain básico — ou pelo menos pare de compartilhar memes com erros de português.

Lego is something most of us knows. This is a opportuity to ask where is our creativity going? From the art of crafting figures to building blocks following our need and desires to have a machine thinking and building following step-by-step instructions to achieve an isolated goal.
Is the creative act then in the question itself, not anymore in the crafting? Are we just delegating the solution of problems, the thinking of how to respond to questions, to machines? Would it be different if delegated to other people?

2025-03-06 04:33:48De ''Dialética do Oprimido'' a ''Like do Oprimido'': A Queda Livre do Debate que Nunca Existiu.
A moda do momento
Fiquei aproximadamente 8 meses sem ter acesso a nenhum dispositivo. Quando consegui novamente o acesso ao smartphone, percebi algo diferente no debate político brasileiro: enquanto a direita estava se engajando em incontáveis números de curtidas e compartilhamentos com memes que demonstravam críticas ao governo e aos seus ainda poucos apoiadores que se humilham para defender o indefensável, a esquerda radical repetia sua imposição intelectual em comentários de vários posts, incluindo textos, vídeos e tweets com frases semelhantes a "vai ler um livro de história" "nunca leu um livro", "eu estou do lado certo da história" e "se eu fosse irracional eu seria de direita". Tudo isso pra tentar passar uma mensagem de que a história é de esquerda. A tese é: será que eles realmente são tão inteligentes como juram?
Fatos que ignoram enquanto cospem jargões do "lado certo da história":
1. A esquerda também tem seus terraplanistas: Anti-vaxxers de organicafé, terraplanistas do gênero, e os que acham que a Coreia do Norte é uma democracia.
2. Viés de confirmação não é monopólio da direita: Eles compartilham estudos "científicos" do Medium como se fossem peer-reviewed, mas desdenham de dados que contradizem sua narrativa.
3. A direita não é um monolito: Tem desde ancaps que calculam até a última casa decimal até bolsominions que acham que a Terra é plana. Generalizar é... bem, irracional.Estudo de Caso (Fictício, mas Verdadeiro):
Larissa, 23 anos, posta sobre "ciência e razão" enquanto defende horóscopo como "ferramenta de autoconhecimento". Acredita que o capitalismo causa depressão, mas não sabe o que é taxa Selic. Larissa é você após três caipirinhas.A Imposição intelectual que ninguém pediu (mas todos recebem de graça)
A esquerda brasileira, em sua cruzada épica para salvar o mundo dos "fascistas que ousam discordar", adotou uma nova estratégia: transformar complexidade política em slogans de camiseta de feira. A frase "se eu fosse irracional, seria de direita" não é original — é plágio descarado da cartilha do Complexo de Deus em Oferta no AliExpress.
O Quebra-Cabeça da superioridade Auto-Delirante
A tese esquerdista se sustenta em três pilares frágeis:
1. A falácia do "lado certo da história": Como se história fosse um jogo de futebol com narração do João Cléber.
2. A ilusão de que citar Foucault = ter QI elevado: Spoiler: decorar "biopoder" não te torna imune a acreditar em astrologia.
3. A crença de que volume de texto = profundidade: 15 parágrafos no Twitter não equivalem a um semestre de Ciência Política.Dado Cruel: Um estudo da Universidade de Cambridge (2022) mostrou que extremistas de ambos os lados cometem erros lógicos similares. A diferença? A esquerda usa palavras mais bonitas para mascarar a burrice.
A hipocrisia do "nunca tocou em um livro" (enquanto compartilham resumo de livro no TikTok)
A acusação preferida — "você não lê!" — esconde uma ironia deliciosa:
- 72% dos "intelectuais de rede social" citam livros que nunca leram além do título (Fonte: Pesquisa Informal do Twitter, 2023).
- Obras citadas como troféu: "1984" (para chamar Bolsonaro de Big Brother), "O Capital" (para justificar o NFT da Gal Gadot), e "Feminismo para os 99%" (para atacar homens heterossexuais que usam sandália de dedo).Pergunta Incômoda: Se ler Marx fosse garantia de racionalidade, por que a União Soviética acabou em pizza (literalmente, considerando a economia deles)?
Quando a autoimagem colide com a realidade (Ou: por que nenhum esquerdista lassa no teste de turing da coerência)
A esquerda adora se pintar como a Última Trincheira da Razão, mas pratica o que critica:
- Exemplo 1: Defendem "ciência" quando convém (vacinas), mas abraçam pseudociência quando é trendy (cristais energéticos contra o capitalismo).
- Exemplo 2: Chamam a direita de "terraplanista", mas acham que inflação se resolve com tabelamento estatal — a versão econômica de "a Terra é sustentada por tartarugas".
- Exemplo 3: Criticam "fake news", mas compartilham teorias de que o agro "envenena a comida" (enquanto comem sushi de supermercado).Frase-Chave: "Racionalidade seletiva é o novo analfabetismo funcional."
Pergunta Final: Se a esquerda é tão racional, por que não usa a "lógica implacável" para resolver algo além do enquadro perfeito de stories no Instagram?
Enfim
O debate "esquerda racional vs. direita irracional" é só mais um episódio da novela "Brasil: O País que Confunde Opinião com Ataque de Ego". Enquanto uns brincam de "quem tem o QI mais alto", o país queima — literalmente, considerando o Pantanal. Talvez a verdadeira irracionalidade seja gastar energia discutindo superioridade moral enquanto o Wi-Fi cai pela décima vez no dia. Racionalidade não tem lado político. Arrogância, por outro lado, é universal. Sua necessidade de se sentir superior só prova que a lacração é o último refúgio dos fracos de argumento. Agora deviam estudar economia básica — ou pelo menos que parem de achar que "Ah, mas o capitalismo!" é um contra-argumento.
Saudade da época em que a esquerda não se fingia de intelectual.

2025-02-19 21:10:15Nostr is a revolutionary protocol that enables decentralized, censorship-resistant communication. Unlike traditional social networks controlled by corporations, Nostr operates without central servers or gatekeepers. This openness makes it incredibly powerful—but also means its success depends entirely on users, developers, and relay operators.
If you believe in free speech, decentralization, and an open internet, there are many ways to support and strengthen the Nostr ecosystem. Whether you're a casual user, a developer, or someone looking to contribute financially, every effort helps build a more robust network.
Here’s how you can get involved and make a difference.
1️⃣ Use Nostr Daily
The simplest and most effective way to contribute to Nostr is by using it regularly. The more active users, the stronger and more valuable the network becomes.
✅ Post, comment, and zap (send micro-payments via Bitcoin’s Lightning Network) to keep conversations flowing.\ ✅ Engage with new users and help them understand how Nostr works.\ ✅ Try different Nostr clients like Damus, Amethyst, Snort, or Primal and provide feedback to improve the experience.
Your activity keeps the network alive and helps encourage more developers and relay operators to invest in the ecosystem.
2️⃣ Run Your Own Nostr Relay
Relays are the backbone of Nostr, responsible for distributing messages across the network. The more independent relays exist, the stronger and more censorship-resistant Nostr becomes.
✅ Set up your own relay to help decentralize the network further.\ ✅ Experiment with relay configurations and different performance optimizations.\ ✅ Offer public or private relay services to users looking for high-quality infrastructure.
If you're not technical, you can still support relay operators by subscribing to a paid relay or donating to open-source relay projects.
3️⃣ Support Paid Relays & Infrastructure
Free relays have helped Nostr grow, but they struggle with spam, slow speeds, and sustainability issues. Paid relays help fund better infrastructure, faster message delivery, and a more reliable experience.
✅ Subscribe to a paid relay to help keep it running.\ ✅ Use premium services like media hosting (e.g., Azzamo Blossom) to decentralize content storage.\ ✅ Donate to relay operators who invest in long-term infrastructure.
By funding Nostr’s decentralized backbone, you help ensure its longevity and reliability.
4️⃣ Zap Developers, Creators & Builders
Many people contribute to Nostr without direct financial compensation—developers who build clients, relay operators, educators, and content creators. You can support them with zaps! ⚡
✅ Find developers working on Nostr projects and send them a zap.\ ✅ Support content creators and educators who spread awareness about Nostr.\ ✅ Encourage builders by donating to open-source projects.
Micro-payments via the Lightning Network make it easy to directly support the people who make Nostr better.
5️⃣ Develop New Nostr Apps & Tools
If you're a developer, you can build on Nostr’s open protocol to create new apps, bots, or tools. Nostr is permissionless, meaning anyone can develop for it.
✅ Create new Nostr clients with unique features and user experiences.\ ✅ Build bots or automation tools that improve engagement and usability.\ ✅ Experiment with decentralized identity, authentication, and encryption to make Nostr even stronger.
With no corporate gatekeepers, your projects can help shape the future of decentralized social media.
6️⃣ Promote & Educate Others About Nostr
Adoption grows when more people understand and use Nostr. You can help by spreading awareness and creating educational content.
✅ Write blogs, guides, and tutorials explaining how to use Nostr.\ ✅ Make videos or social media posts introducing new users to the protocol.\ ✅ Host discussions, Twitter Spaces, or workshops to onboard more people.
The more people understand and trust Nostr, the stronger the ecosystem becomes.
7️⃣ Support Open-Source Nostr Projects
Many Nostr tools and clients are built by volunteers, and open-source projects thrive on community support.
✅ Contribute code to existing Nostr projects on GitHub.\ ✅ Report bugs and suggest features to improve Nostr clients.\ ✅ Donate to developers who keep Nostr free and open for everyone.
If you're not a developer, you can still help with testing, translations, and documentation to make projects more accessible.
🚀 Every Contribution Strengthens Nostr
Whether you:
✔️ Post and engage daily\ ✔️ Zap creators and developers\ ✔️ Run or support relays\ ✔️ Build new apps and tools\ ✔️ Educate and onboard new users
Every action helps make Nostr more resilient, decentralized, and unstoppable.
Nostr isn’t just another social network—it’s a movement toward a free and open internet. If you believe in digital freedom, privacy, and decentralization, now is the time to get involved.

2025-05-14 06:48:45Has the architect Greg Chasen considered it when rebuilding the house just one year before the catastrophe? Apparently not! Another of his projects was featured on the Value of Architecture as properties with design integrity.
This is a super interesting subject. The historic character, livability, and modern disaster-resistance is a triangle where you often have to pick just one or two, which leads to some tough decisions that have major impacts on families and communities. Like one of the things he mentions is that the architect completely eliminated plants from the property. That's great for fire resistance, but not so great for other things if the entire town decides to go the same route (which he does bring up later in the video). I don't think there's any objectively right answer, but definitely lots of good (and important) discussion points to be had.

2025-02-09 16:50:04There has been a good bit of discussion on Nostr over the past few days about the merits of zaps as a method of engaging with notes, so after writing a rather lengthy article on the pros of a strategic Bitcoin reserve, I wanted to take some time to chime in on the much more fun topic of digital engagement.
Let's begin by defining a couple of things:
Nostr is a decentralized, censorship-resistance protocol whose current biggest use case is social media (think Twitter/X). Instead of relying on company servers, it relies on relays that anyone can spin up and own their own content. Its use cases are much bigger, though, and this article is hosted on my own relay, using my own Nostr relay as an example.
Zap is a tip or donation denominated in sats (small units of Bitcoin) sent from one user to another. This is generally done directly over the Lightning Network but is increasingly using Cashu tokens. For the sake of this discussion, how you transmit/receive zaps will be irrelevant, so don't worry if you don't know what Lightning or Cashu are.
If we look at how users engage with posts and follows/followers on platforms like Twitter, Facebook, etc., it becomes evident that traditional social media thrives on engagement farming. The more outrageous a post, the more likely it will get a reaction. We see a version of this on more visual social platforms like YouTube and TikTok that use carefully crafted thumbnail images to grab the user's attention to click the video. If you'd like to dive deep into the psychology and science behind social media engagement, let me know, and I'd be happy to follow up with another article.
In this user engagement model, a user is given the option to comment or like the original post, or share it among their followers to increase its signal. They receive no value from engaging with the content aside from the dopamine hit of the original experience or having their comment liked back by whatever influencer they provide value to. Ad revenue flows to the content creator. Clout flows to the content creator. Sales revenue from merch and content placement flows to the content creator. We call this a linear economy -- the idea that resources get created, used up, then thrown away. Users create content and farm as much engagement as possible, then the content is forgotten within a few hours as they move on to the next piece of content to be farmed.
What if there were a simple way to give value back to those who engage with your content? By implementing some value-for-value model -- a circular economy. Enter zaps.
Unlike traditional social media platforms, Nostr does not actively use algorithms to determine what content is popular, nor does it push content created for active user engagement to the top of a user's timeline. Yes, there are "trending" and "most zapped" timelines that users can choose to use as their default, but these use relatively straightforward engagement metrics to rank posts for these timelines.
That is not to say that we may not see clients actively seeking to refine timeline algorithms for specific metrics. Still, the beauty of having an open protocol with media that is controlled solely by its users is that users who begin to see their timeline gamed towards specific algorithms can choose to move to another client, and for those who are more tech-savvy, they can opt to run their own relays or create their own clients with personalized algorithms and web of trust scoring systems.
Zaps enable the means to create a new type of social media economy in which creators can earn for creating content and users can earn by actively engaging with it. Like and reposting content is relatively frictionless and costs nothing but a simple button tap. Zaps provide active engagement because they signal to your followers and those of the content creator that this post has genuine value, quite literally in the form of money—sats.
I have seen some comments on Nostr claiming that removing likes and reactions is for wealthy people who can afford to send zaps and that the majority of people in the US and around the world do not have the time or money to zap because they have better things to spend their money like feeding their families and paying their bills. While at face value, these may seem like valid arguments, they, unfortunately, represent the brainwashed, defeatist attitude that our current economic (and, by extension, social media) systems aim to instill in all of us to continue extracting value from our lives.
Imagine now, if those people dedicating their own time (time = money) to mine pity points on social media would instead spend that time with genuine value creation by posting content that is meaningful to cultural discussions. Imagine if, instead of complaining that their posts get no zaps and going on a tirade about how much of a victim they are, they would empower themselves to take control of their content and give value back to the world; where would that leave us? How much value could be created on a nascent platform such as Nostr, and how quickly could it overtake other platforms?
Other users argue about user experience and that additional friction (i.e., zaps) leads to lower engagement, as proven by decades of studies on user interaction. While the added friction may turn some users away, does that necessarily provide less value? I argue quite the opposite. You haven't made a few sats from zaps with your content? Can't afford to send some sats to a wallet for zapping? How about using the most excellent available resource and spending 10 seconds of your time to leave a comment? Likes and reactions are valueless transactions. Social media's real value derives from providing monetary compensation and actively engaging in a conversation with posts you find interesting or thought-provoking. Remember when humans thrived on conversation and discussion for entertainment instead of simply being an onlooker of someone else's life?
If you've made it this far, my only request is this: try only zapping and commenting as a method of engagement for two weeks. Sure, you may end up liking a post here and there, but be more mindful of how you interact with the world and break yourself from blind instinct. You'll thank me later.

2025-05-14 06:12:19We asked members of the design community to choose an artifact that embodies craft—something that speaks to their understanding of what it means to make with intention. Here’s what they shared.
A vintage puzzle box, a perfectly tuned guitar, an AI-powered poetry camera. A daiquiri mixed with precision. A spreadsheet that still haunts muscle memory. Each artifact tells a story: not just about the thing itself, but about the choices of the creator behind it. What to refine, what to leave raw. When to push forward, when to let go. Whether built to last for generations or designed to delight in a fleeting moment, the common thread is that great craft doesn’t happen by accident. It’s made.

2025-05-18 11:02:09比特币持有者在 iPhone 上的安全使用注意事项
引言:iPhone 与安卓的对比
当涉及移动设备安全,比特币持有者面临着在 iPhone 和安卓设备之间的选择。从安全硬件来看,安卓阵营中确有一些型号配备了类似于 Apple Secure Enclave 的硬件安全模块,例如 Google Pixel 手机内置的 Titan M/M2 安全芯片,用于保障启动流程和存储敏感数据us.norton.com;三星的旗舰机型则集成了 Samsung Knox 多层安全平台,经过多国政府机构认证,可在硬件层面保护设备及其中数据us.norton.com。这些安全措施大大提升了设备抵御恶意攻击和数据泄露的能力。然而,需要注意的是:具备此类高级安全特性的安卓机型在市场上相对少见,并非安卓阵营的普遍标准us.norton.com。安卓生态高度碎片化,不同厂商的安全实践差异悬殊;除了少数注重安全的厂商(如 Google、Samsung)外,许多设备缺乏统一的安全保障水平us.norton.com。尤其在二手市场上,安卓设备型号繁杂且来源不一,一些旧款或改装机型可能缺少最新的安全芯片或更新,使安全性难以得到保证。
相比之下,Apple iPhone 全系列自带硬件级的安全隔区(Secure Enclave),统一的闭源系统和严格的应用审核使其安全措施在所有设备上保持一致us.norton.com。同时,iPhone 引入的 Face ID(三维结构光人脸识别)在生物识别安全性上具有独特优势。Apple官方数据显示,Face ID 被他人解锁的概率只有 百万分之一,远低于指纹识别的五万分之一。这源于Face ID利用红外点阵投射捕捉面部3D结构,难以被照片或面具所破解,大幅减少了伪造生物特征解锁的风险。此外,相较许多安卓手机仍依赖的二维人脸识别或电容/光学指纹,Face ID 在抗攻击能力上更胜一筹——例如普通指纹残留可能被提取复制,而二维人脸解锁曾被照片轻易骗过,但Face ID的深度感应技术有效避免了这些漏洞。
综上所述,在移动设备安全领域,iPhone 为比特币等高价值敏感资产的持有者提供了更为稳健和统一的安全基础。尽管某些高端安卓手机具有可圈可点的安全功能,但鉴于这类机型凤毛麟角、安卓设备更新和管控的不统一,以及生物识别方案的差异,我们强烈建议将 iPhone 作为比特币手持设备的唯一选择。从硬件加密到生物识别,iPhone 的封闭生态和领先技术能为数字资产提供更可靠的防护,而安卓设备在这一场景下则存在诸多先天不足。
小结: 安卓阵营虽有Pixel Titan芯片、Samsung Knox等亮点,但安全机型数量有限且良莠不齐;iPhone凭借统一的安全架构和先进的Face ID,在保护敏感数据方面更胜一筹。为确保比特币等资产安全,选择安全可靠的iPhone 是明智之举。
iPhone 安全配置指南
选择了 iPhone 作为比特币存取和通讯设备后,仍需进行细致的安全设置,以最大化利用其安全潜力。以下是针对比特币持有者的 iPhone 安全配置要点:
-
禁用 Face ID/Touch ID 生物解锁,改用强PIN码: 建议关闭面容ID解锁功能,改用6位以上的数字PIN码(或更复杂的字母数字密码)作为解锁方式。在紧急情况下,生物识别容易被他人强制利用(例如他人将手机对准机主面部强行解锁),而记忆型的PIN码只有持有人知晓,更难以被胁迫获取。此外,法律上某些地区对强制提供生物特征和提供密码有所区别,这也使得使用PIN码在极端情况下更有保障。
-
启用自动锁定(1分钟) 将设备设为闲置1分钟后自动锁定屏幕。从安全角度出发,锁定等待时间越短越好。1分钟的设置可确保即使暂时离开或疏忽,设备也会很快上锁,防范他人乘虚而入。养成随手锁屏的习惯固然重要,但有了短自动锁定时间作为双重保障,安全性更上一层楼。
-
开启输错10次自动抹除: 在“设置 > 面容ID/触控ID与密码”中启用“连续输错10次密码抹掉数据”功能。一旦有人反复尝试猜测密码,该功能会在第十次错误尝试后自动抹除手机数据。很多用户担心该设置存在风险,但事实上 误触发的可能性极低。sspai.comsspai.com实际测试表明,iPhone在多次输错密码时会触发累进的延迟惩罚机制:第五次错误需要等待1分钟,第六次错误等待5分钟,第7-8次各等待15分钟,第9次等待1小时sspai.comsspai.com。要连续进行十次独立的错误尝试至少需要约96分钟,在现实中“熊孩子”乱按连续清空数据几乎不可能发生sspai.com。相反,该功能对抗暴力破解极为有效——正如2015年圣贝纳迪诺恐怖袭击案中,嫌犯所用的iPhone就启用了十次错误清除,使FBI也无法轻易尝试破解en.wikipedia.org。总之,此项设置能将设备落入他人之手时的数据泄露风险降至最低。
-
利用应用级 Face ID 控制(iOS 18+):升级至iOS 18或更新版本,充分利用其新增的应用锁定功能。长按主屏某个应用图标,可以找到“需要Face ID”选项,将该应用加锁theverge.com。被加锁的应用每次打开都需要通过Face ID身份验证(即使手机已解锁)。建议对 聊天通讯、密码管理、交易所App 等敏感应用启用此功能。例如,将微信、Signal、邮件客户端等设置为打开需Face ID验证,以防范他人在您手机解锁的短暂间隙内获取其中内容。应用级Face ID锁定为设备提供了第二道防线:即使手机本身已解锁,敏感应用和数据仍受到保护。

建议购买第二台 iPhone 或 iPad 作为“备用解锁入口”: 利用 Apple 的“信任链”机制,为同一 Apple ID 配置多台受信任设备(如两台 iPhone 或 iPhone+iPad)。这样即使主设备丢失或被抹除,备用设备依然可以访问并恢复 iCloud 端到端加密数据。其安全本质类似于“1-of-N 多签”,即任一设备均可独立解锁所有云数据,但无需多设备联合协商,恢复更灵活。注意:这与比特币的m-of-n多签不同,Apple的信任链是单设备多入口,安全性和便利性权衡需根据个人需求评估。官方说明参见:Apple平台安全白皮书(Keychain与信任链)
-
建议购买 YubiKey 等硬件安全密钥作为 Apple ID 验证要素: 由于信任链机制下新设备加入时,身份验证成为潜在攻击点(如钓鱼、社工、短信劫持),推荐为 Apple ID 配置 YubiKey 或兼容 FIDO2/U2F 的硬件安全密钥。启用后,只有插入并触发硬件密钥的情况下,才能完成新设备授权、敏感操作或账户恢复,有效阻止网络钓鱼和大部分远程攻击。该方法可显著提升账户安全,降低因凭证泄漏或验证被劫持导致的信任链攻破风险。Apple 官方说明:为 Apple ID 添加安全密钥
通过上述配置,iPhone 将处于一个平衡了便利性和安全性的状态:日常解锁采用PIN码确保意外情况下设备不被强制解锁,短自动锁和十次清除严防暴力破解,而应用级加锁进一步保障重要数据不外泄。
小结: 按照以上指南对iPhone进行安全配置,可以大幅提升设备在实际使用中的抗攻击能力。生物识别解锁的取舍、自动锁定和清除机制、以及iOS 18引入的应用加锁功能相结合,全方位地巩固了手机作为比特币手持设备的安全基石。
关于自动抹除的常见质疑回应
启用“输错10次自动抹除”功能后,不少用户会提出疑虑,主要集中在两个方面:其一,担心儿童误操作或本人一时疏忽导致设备数据被抹掉;其二,担心万一手机数据被抹除,设备本身价值受损。针对这些质疑,我们进行如下回应:
-
“熊孩子乱按怎么办?” 前文已提及,iPhone设计了渐进延时机制,使得连续十次错误输入并非易事sspai.comsspai.com。孩子无意识地反复点击相同数字,系统只视为一次错误sspai.com;而多次不同错误则会触发越来越长的锁定时间,很难真的连续试满十次sspai.com。实践中,要触发十次错误清除需要近两个小时且每次输入都不同,这种情景极不现实sspai.com。因此,只要平时看护好设备,误抹除几乎无需担心。相反,如果没有该功能,一旦设备遗失或被不法分子获取,后果将不堪设想——对方可以在足够时间和专业工具协助下尝试无限次解锁,从而获取您手机中的一切秘密。
-
“数据没了岂不可惜?” 我们强调,比特币持有者手机中存储的敏感信息价值远超设备本身。手机里可能有助记词、私钥线索、交易记录截图,甚至包含您社交账户中关于资产的对话。在攻击者眼中,这些数据的价值胜过一部手机。与其担心设备被误清除,不如担心设备落入他人之手数据遭泄露的风险。况且,对于重要数据您应当早有备份(下文将讨论启用iCloud云备份的问题)。即使真发生误清除,有备份在手也能恢复;但若数据被不法分子窃取,一旦造成资产损失将无法挽回。因此,从风险权衡来看,“宁可误删,不可被盗”——自动抹除是最后一道保障,在极端情况下保护您的数字资产不被侵害。
总而言之,这一功能的利远大于弊。儿童误触可以通过良好监护和系统延时设计来防范,而一旦启用,您将获得巨大的安心:手机若遭试图破解,可以自毁以保全数据安全。这正是比特币持有者应有的安全理念:舍弃设备保安全,数据和资产永远优先于硬件。随着良好备份策略的配合(例如iCloud加密备份),启用自动抹除几乎没有后顾之忧。
小结: 针对自动抹除功能的疑虑更多是误解。iPhone的机制使得误触发几率极低,而其提供的数据安全保障却是无可替代的。比特币等敏感资产持有者应放下顾虑,优先保护数据安全——哪怕代价是设备被清除,也胜过数据落入他人之手。
iCloud 备份的争议与建议
在确保本地设备安全的同时,妥善备份数据同样关键。对于比特币持有者而言,启用 iCloud 云备份可以提供额外的一层安心:万一设备遗失、损坏或被抹除后,仍有机会恢复重要信息。然而,围绕iCloud备份的安全性一直存在争议,我们在此详细分析并给出建议:
首先强烈建议在启用iCloud备份的同时,务必开启「高级数据保护」(Advanced Data Protection, ADP)。默认情况下,iCloud云备份的数据加密密钥由Apple掌管,这意味着苹果公司在法律要求下能够解密并提供您的备份数据support.apple.comsupport.apple.com。而开启高级数据保护后,备份所涉及的大部分数据将采用端对端加密,只有您的受信任设备掌握解锁密钥support.apple.com。据苹果官方说明,在ADP模式下,即便苹果公司也无法读取您的备份内容support.apple.com。因此,高级数据保护能够将使用云备份可能带来的隐私泄露风险降至最低(前提是您妥善保管好自己的账户和恢复密钥)。
启用云备份常见的疑虑是:“会不会把我的钱包私钥也备份上去,万一云被攻破岂不危险?” 实际上,多数主流比特币/加密钱包软件不会将核心密钥(如助记词或扩展公钥xpub)存储在云备份中。很多钱包在设计时就要求用户自行备份助记词,而不会把这些高度敏感的数据写入应用沙盒,可被iCloud备份抓取。同样地,一些钱包应用甚至提醒用户关闭iCloud备份以防助记词泄露support.wallet.coinex.com。换言之,开启iCloud备份并不会将您的私钥上传(除非个别钱包特别设置了云同步,但大多数非托管钱包都没有这么做)。当然,为审慎起见,您可以查阅所用钱包的文档或设置,确认其是否有备份敏感信息到云的选项,并据此做出取舍。
与此同时,我们更加关心的是其他应用的数据完整备份。对于比特币持有者来说,聊天记录、笔记文档和工作应用的数据往往同样敏感且重要。例如,常用通讯软件(微信、Telegram、Signal 等)中的聊天可能涉及交易细节或人脉网络;办公应用如钉钉、飞书则包含财务往来或业务资料。这些应用的数据都会包含在iCloud整机备份中并被完整保存,一旦手机丢失或损坏,可以通过云备份原样恢复。support.apple.com值得一提的是,在高级数据保护开启且不泄漏密钥的前提下,这些备份数据即使存储在苹果服务器上也是安全的,第三方无法解读其中内容。
进一步的好处是:利用备份进行调查取证。假设最坏情况发生——您的手机被抹除或遗失,但是事先有一份最新的iCloud备份。在紧急需要时,您可以在一台新的iPhone上恢复这份备份。在恢复完成后,切断新设备的网络连接(拔掉SIM卡或不连Wi-Fi)。由于备份恢复会还原您的应用登录状态和本地数据,新设备在离线情况下将维持原手机当时的登录环境。您可以打开聊天应用、邮件、照片等查看内容,就像原手机一样。离线操作确保应用不会因为检测到新设备而要求重新登录,也避免了云端数据被远程清除的可能。这对于事后取证、提供线索给执法部门或自我调查都极为有利。比如,若涉及盗窃诈骗案件,这部离线恢复的手机里保留的聊天记录、交易凭证可以作为关键证据。而一旦联网,这些应用可能出于安全考虑登出账户或拉取最新状态,反而不利于保留原始证据。因此,有意识地保存一份完整云备份,并在需要时以离线方式恢复,是一种非常巧妙的应对策略。
小结: 尽管人们对云备份心存疑虑,但通过启用高级数据保护,iCloud备份既能提供数据恢复便利,又充分保障了隐私安全。大多数加密钱包不会上传私钥等核心数据,而聊天、办公等应用的数据则可完整份以备不时之需。在平衡安全与可用性的前提下,开启iCloud备份(搭配ADP加密)是明智之举——它让您在设备意外损坏或丢失时依然有据可查、有据可证。
高级数据保护与密码学机制分析
最后,我们从更宏观的视角,结合真实案例和技术原理,深入探讨苹果设备与云服务的安全性,以及高级数据保护(ADP)所依赖的密码学机制。这部分将涵盖苹果在多个国家遭遇的解锁争议、ADP 的运作及其与实体安全密钥的配合、以及关于苹果是否存在解密后门的分析。
苹果与执法部门的解锁事件
过去数年间,多起高调事件凸显了设备加密与执法取证之间的矛盾。美国国会山骚乱事件(2021年1月6日)中,执法部门缴获了大量嫌疑人的手机。据报道,不少嫌犯使用的是iPhone,调查人员能够从苹果获取其中的数据 但途径主要是通过 iCloud 云备份 而非直接破解设备thedailybeast.com。由于当时高级数据保护尚未推出或未启用,苹果依然持有那些嫌疑人iCloud账户的备份密钥,因此在收到合法的执法请求后,苹果向FBI提供了嫌疑人的iCloud备份内容,其中包括视频、照片和聊天记录等关键证据thedailybeast.com。这些数据帮助当局重构了案件过程,也反映出如果用户没有使用端到端加密备份,云端数据在法律压力下并非牢不可破。
相反,在更早的**圣贝纳迪诺恐怖袭击案(2015)**中,FBI面对一部启用了强加密的嫌犯iPhone却陷入僵局。那是一个运行iOS 9的 iPhone 5C,开启了PIN码锁和10次输错清除功能en.wikipedia.org。由于该设备上的本地数据经过设备加密且苹果并不持有密钥,FBI无法提取其中信息,遂求助苹果公司要求破解。但苹果以维护所有用户安全为由拒绝编写后门固件来绕过安全限制,引发了一场著名的法律拉锯en.wikipedia.orgen.wikipedia.org。最终执法部门辗转通过第三方工具解锁了手机,但苹果的立场十分明确:即便面对恐怖主义案件,也不会为单次事件在系统中留下后门。这一事件凸显出现代iPhone设备本地加密之强大——在没有用户密码的情况下,即使连厂商都无能为力,除非另辟蹊径寻求系统或硬件漏洞。
iCloud 在中国与英国的访问争议
在不同国家,苹果围绕用户数据加密与政府监管的博弈也在上演。中国方面,自2018年以来苹果将中国大陆 iCloud 服务交由“云上贵州”公司运营,数据存储和加密密钥均留在境内zh.amnesty.org。依据中国《网络安全法》,云服务运营者有义务为执法和国家安全机关提供“技术支持和协助”zh.amnesty.org。这意味着若中国警方出于刑侦需要向云上贵州调取某用户的 iCloud 数据,该公司必须配合提供,几乎没有拒绝的空间zh.amnesty.org。更重要的是,苹果把中国用户的 iCloud 加密密钥也存放在中国,一旦收到合法命令要求解密数据,苹果和云上贵州只能遵从zh.amnesty.org。换言之,在标准数据保护模式下,中国当局有途径通过法律手段获取本地存储的iCloud明文数据。这引发了人们对隐私的担忧:如果没有端到端加密,中国的用户数据可能在政府要求下被查看。然而如果用户开启高级数据保护,使得苹果也无法解读备份内容,那么即便在中国,此举从技术上为用户争取到了更高的私密性(前提是中国地区允许开启ADP——截至目前,苹果并未在中国禁用该功能,国区用户依然可以自行启用高级数据保护support.apple.comsupport.apple.com)。
再看英国的情况。英国政府近年以打击犯罪和恐怖主义为由,不断向科技公司施压要求提供加密数据的后门访问权。2023年底,英国援引《调查权力法》(IPA)秘密向苹果发出“技术能力通知”(TCN),要求苹果在全球范围内为英国安全部门提供对加密iCloud内容的解锁途径cnbeta.com.tw。这实际上等同于要求苹果破坏其端到端加密体系,留出一个只有政府能用的后门。苹果对此断然拒绝,并做出强硬回应:宁愿撤除在英服务,也不会妥协安全底线cnbeta.com.tw。结果是,苹果选择在英国境内停止提供高级数据保护功能给新用户。已有启用ADP的英国用户被通知需在宽限期内手动将其关闭,否则将无法继续使用iCloud备份cnbeta.com.tw。苹果在声明中表示对此深感失望,但为了遵守当地法律别无他法cnbeta.com.tw。下面这张截图显示了英国用户在系统中看到的提示信息,明确告知ADP服务不再可用
苹果针对英国地区做出的ADP功能调整通知。英国政府要求能够解密用户数据,迫使苹果撤回了对英国用户的新端到端加密备份支持cnbeta.com.twcnbeta.com.tw。苹果声明强调只有用户本人才能解读其加密数据,并重申不会在产品中留下执法后门cnbeta.com.tw。
这一英国内外的罕见举措表明,各国政府正日益重视加密带来的执法障碍,而苹果则在平衡用户隐私和法律要求之间走钢丝。尽管英国的情况迫使苹果让步(取消当地ADP),但苹果并未真的为政府打造解密后门,而是通过限制功能来表明态度——这与其长期立场一致:绝不在加密产品中留后门,即使承受业务上的损失cnbeta.com.tw。
高级数据保护与安全密钥
高级数据保护(ADP) 是苹果于 iOS 16.2 引入的一项可选功能,其核心是在用户选择开启后,将包括设备备份在内的大部分 iCloud 数据升级为端到端加密存储support.apple.comsupport.apple.com。开启ADP有两个前提:账户已启用双重认证,以及设置了账户恢复联系人或恢复密钥,以防用户遗失访问权限support.apple.comsupport.apple.com。在ADP模式下,Apple不再持有绝大部分云数据的解锁密钥,这些密钥只存在于用户的受信任设备中support.apple.com。这意味着,即便苹果公司收到政府索取数据的要求或其服务器遭黑客攻击,没有密钥的加密数据对任何第三方都是无意义的乱码。正如苹果声明所言:“只有拥有数据的用户才能解密,Apple 无法访问端对端加密的数据”cnbeta.com.tw。可以说,ADP将用户云数据的主导权完全交还给用户自己,从而彻底消除了苹果方面潜在的数据泄露点。
为了进一步增强账户安全,苹果在_iOS 16.3_开始支持绑定实体安全密钥(如 YubiKey)作为 Apple ID 的额外两步验证方式sspai.com。过去Apple ID登录主要依赖密码+发送到受信设备的验证码,但假如用户Apple ID密码泄露,攻击者可能利用社会工程获取验证码。而引入实体安全密钥后,用户可以要求任何新的登录尝试都必须提供物理密钥认证才能完成。这相当于给 Apple ID 上了一把“硬件锁”。对于比特币持有者而言,这一步非常值得配置:即使黑客骗取了您的苹果账号密码,没有您的YubiKey或同类FIDO2安全密钥,他仍无法登录您的iCloud或停用您的ADP。安全密钥本身具有防钓鱼特性,它不会把可被重用的机密泄露给假网站,再加上密钥私藏于硬件内部不可导出,使得账户保护达到新的高度sspai.comsspai.com。简而言之,**“ADP + 硬件安全密钥”**的组合为用户云数据打造了双重护城河:前者确保云上数据加密不被窥探,后者确保账户本身不被劫持利用。
需要注意的是,启用ADP后如果遗失所有设备且忘记密码,苹果无法帮您找回数据support.apple.com。这就像您把保险箱钥匙只握在自己手里而不交给任何人保管,其安全性空前提高,但也意味着责任完全在您。因此请务必牢记Apple ID密码,保管好恢复密钥或紧急联系人。一旦平衡好便利与安全,这套机制将为您的数字资产提供堪比硬件钱包的云端保障。
后门密钥与私钥不可拆分性
现代加密体系的设计使得用户私钥与设备环境密不可分。在苹果的生态中,每台设备都拥有由硬件生成的唯一加密根密钥。例如,安全隔区(Secure Enclave)内嵌入了设备唯一标识符UID作为根密钥,UID由安全硬件随机生成并烧录至芯片中help.apple.com。这个UID既不与任何其他设备标识相关,也无法被设备外的任何人(包括苹果官方)获取help.apple.com。同时,用户的解锁密码与该UID进行数学“交织”(entangle),共同派生出加密密钥help.apple.com。换言之,设备硬件密钥和用户密码共同决定了数据加密密钥,没有这两者就无法还原密钥。这体现了用户私钥对设备及用户身份的强绑定——苹果没有第三方密钥可以绕过这一绑定关系help.apple.comhelp.apple.com。
从密码学角度来看,如果苹果试图在上述体系中插入一个额外的“后门密钥”,将面临巨大的技术困难,并且这样的异常极易被察觉。设想苹果通过异或(XOR)或 Shamir 密钥共享等方式,将一个后门密钥与用户密钥组合:
- 实现层面的异常:用户设备在正常情况下应当能够独立完成解密/签名操作。如果加入隐藏密钥份额,意味着设备单凭用户自己的密钥无法完成某些解密,必须依赖苹果持有的那一份。这样的改动会造成额外的密钥协商步骤或异常的解密失败。例如,若苹果将后门密钥与用户密钥异或生成实际工作密钥,那么单用用户密钥将无法解密出正确结果,设备可能需要静默地向苹果服务器请求密钥片段或进行额外计算。这类非预期的通信或计算步骤很容易被安全研究者通过流量分析或逆向工程发现端倪。再比如采用 Shamir’s Secret Sharing 等门限方案,如果苹果持有一份密钥碎片,设备在解密时就需要满足门限条件,这通常意味着需要苹果的参与或预置公钥,从而在协议日志中留下异常痕迹。任何偏离常规协议的做法——无论是多传输一段数据,还是多保存一段密钥信息——都可能成为研究者捕捉的线索。历史经验表明,密码协议中的“奇怪之处”往往预示潜在漏洞或后门:例如 NSA 推出的 Dual_EC_DRBG 伪随机数生成器由于使用了异常常数,被专家迅速怀疑存在后门;著名密码学家施奈尔(Bruce Schneier)就曾直言 Dual_EC_DRBG 中的后门“相当明显”,呼吁业界停止使用en.wikipedia.org。由此可见,试图暗中插入额外密钥会在数学实现上留下破绽,而资深密码学者和安全社区有足够能力识别这些反常之处。
进一步,从门限签名理论对比苹果现有密钥管理,可以加深这一不可行性的理解。门限密码学允许将密钥拆分给多方持有,只有达到预定门槛的份额才能重构密钥或执行签名解密toc.csail.mit.edumedium.com。其优点在于提高了密钥托管的安全性,需要多方协作才能解锁秘密。然而,这种机制是公开设计的一部分,各参与方和流程都是明示的。例如在某些区块链多重签名方案中,多个私钥持有者共同生成交易签名,每个人都知晓门限机制的存在。相较之下,苹果在产品中的密钥管理要么是完全由用户端掌握密钥(如iPhone本地数据加密,密钥存在Secure Enclave中),要么是在用户许可下由苹果代管(如传统iCloud云备份未启用高级加密时,苹果保存备份密钥)。苹果并没有公开采用“两方门限”的模式来和用户分享密钥,否则等于声明“用户单方无法完全掌控自己的解密权”。如果苹果暗中采用门限签名让自己持有一份密钥碎片,本质上就是一种**变相密钥托管(Escrow)**行为。这样的做法会明显偏离苹果宣称的零后门立场,与其在隐私政策中反复强调的原则相违背。值得注意的是,苹果在其官方隐私声明中明确表示:“我们从未在任何产品或服务中创建过后门或万能解锁主密钥”apple.com。因此,从理论和实践双重层面来看,用户私钥与潜在后门密钥是难以在不被发现的情况下拆分存在的。任何试图将二者解耦的举措都会引起体系架构的异常,进而难逃专家法眼。
加密社区对后门的发现与审计
在当今的安全生态中,不存在“悄无声息的后门”。一旦厂商试图在加密方案中掺入后门密钥,全球的密码学社区和安全研究人员都有多种手段将其揪出。下面从几个方面概述社区常用的后门检测与审计方法:
-
开源协议分析:安全专家偏好开源的软件和协议,因为源码透明意味着任何可疑的算法修改、密钥处理流程都暴露在公众视野中。通过阅读和形式化分析公开的协议规范,研究者可以发现是否有多余的密钥交换步骤或异常的参数。例如,Signal通信协议的源代码和技术细节是完全公开的,全球专家曾多次审阅其实现,验证其端到端加密未存在后门linkedin.com。事实证明,公开透明带来的是更严苛的监督,任何隐秘加入的密钥参数都有可能被审计人员发现。正如业内人士所指出的,Signal 采用开放源码意味着安全专家可以独立审计其代码以核实安全性linkedin.com。类似地,许多现代加密库都会经过社区审视,以确保其中没有“暗门”。
-
逆向工程与二进制审计:对于闭源的软件(例如苹果自身的系统组件),安全研究者会运用逆向工程技术来分析应用的二进制代码和运行时行为。一旦苹果的加密实现存在未公开的密钥使用,比如在本地程序中引用了某个神秘常量或调用了隐藏的密钥解密函数,逆向工程往往能还原这些逻辑。专业团队通过调试、反编译、动态埋点等方式重现协议的握手过程,查看每一步骤所用的密钥材料。如果过程中出现与官方文档不符的环节(例如本应由用户设备生成的密钥却从外部获取),将立即引发怀疑。此外,安全社区定期举办的漏洞挖掘和破解挑战赛也扮演重要角色——顶尖黑客会竞相攻破苹果设备的加密层,并公开报告发现的问题。过去这些努力揭示了一些实现漏洞(如内存越界、0day攻击途径),但从未曝出“苹果预留万能密钥”之类的后门。一例典型事件是2017年有黑客成功解密了Secure Enclave固件以研究其中机理,结果证实即便取得固件代码,攻击者仍无法提取到任何用户密钥或后门凭证ciso.economictimes.indiatimes.com。这一结论进一步增强了业界对苹果加密实现中无后门的信心。
-
网络流量与协议行为分析:加密协议往往涉及设备与服务器的交互流程。研究人员会抓包和监控这些网络流量,分析协议握手时交换的消息格式和内容。如果苹果尝试在密钥协商时暗中插入自己的公钥或请求额外数据,流量分析将捕捉到异常的报文模式。例如,在正常的端到端加密通信中,设备之间交换彼此的公钥证书,不应有第三方公钥悄然出现。而所谓“幽灵用户”后门提案正是要求服务提供商在群聊中偷偷加入一个看不见的第三方公钥。这样的方案被广泛批评因为它破坏了用户验证通信对端身份的机制,需要服务器隐藏通知才能欺骗用户lawfaremedia.org。密码学家指出,这将削弱认证过程并带来新漏洞,因此难以在不被发现的情况下实施lawfaremedia.org。由此可见,通过流量异常识别潜在后门是切实可行的。当年的GCHQ“幽灵用户”建议一提出,就被包括苹果在内的业界联合抵制,47家机构和专家联名公开信指出该做法“对网络安全构成严重威胁”internetsociety.orgsilicon.co.uk,可见社区对这类后门手段有高度警惕性。
-
独立审计和信任链验证:许多安全敏感的加密功能会接受独立机构的审计,以建立公众信任。比如苹果的 iCloud 钥匙串(Keychain) 采用多层加密和信任链机制,其设计文档表明敏感信息的密钥始终需要Secure Enclave参与才能解锁techrepublic.com。有第三方评估指出,钥匙串中的私密数据即便保存在云端也是经过高强度加密的,任何人(包括苹果)都无法直接读取明文techrepublic.com。这一架构经过多轮外部安全会议研讨和学者研究,至今未出现被植入后门的迹象。同样,苹果设备中的 Secure Enclave 安全隔区 也多次成为学术研究和黑客大会的焦点。研究人员通过攻击Secure Enclave找出了少数漏洞(例如早期A7-A11芯片存在硬件级漏洞ciso.economictimes.indiatimes.comciso.economictimes.indiatimes.com),但这些漏洞只是实现瑕疵,并非有意留出的后门。实际上,正是这些公开的审计和破解挑战证明了Secure Enclave的设计初衷:即使攻击者获得硬件或固件访问权,仍无法提取出主密钥ciso.economictimes.indiatimes.com。学术界和白帽黑客社区通过反复的审查和渗透测试,为苹果的“零后门”承诺提供了有力的背书。换言之,加密社区的独立审计机制确保了任何后门都难以隐藏;只有经得起各方检验的系统,才能真正赢得用户信任。
综上所述,在强大的社区监督下,任何后门密钥的存在都会留下蛛丝马迹,并最终被曝光。无论是协议分析、逆向工程还是实网监测,多层次的手段使得厂商无法神不知鬼不觉地在成熟加密方案中藏入后门。这也是为什么苹果等公司反复强调没有后门:一旦撒谎,终将被揭穿,信用荡然无存。
iCloud 钥匙串信任链下的全局数据加密密钥(DEK)机制研究
苹果的高级数据保护(Advanced Data Protection)引入了端到端加密,将大部分 iCloud 数据的密钥仅存储在用户的受信设备上support.apple.com。在该机制下,每个用户的 iCloud 帐户针对各数据类别生成自己的“全局”数据加密密钥(Data Encryption Key, DEK),这些密钥受 iCloud 钥匙串的信任链机制保护。下面将详细探讨全局 DEK 的生成、分发与封装,多设备场景下的生命周期变化,以及苹果保障 DEK 安全和确保服务器从未获取明文 DEK 的技术手段。
全局 DEK 的生成、更新与轮换
初始生成:当用户首次在支持的设备上启用高级数据保护时(需运行 iOS 16.2、macOS 13.1 等新版系统,并开启双重认证),系统会在该设备上本地生成全局数据加密密钥。实际上,每个受端到端加密保护的 iCloud 服务(例如云备份、照片、笔记等)都有各自的 CloudKit 服务密钥对,其私钥用作该类别数据的主加密密钥support.apple.comsupport.apple.com。这些服务密钥使用安全随机算法在用户受信设备上创建,具有唯一性,并由设备的安全硬件保护。启用高级数据保护时,设备会将之前由苹果保存的云端密钥从苹果的硬件安全模块(HSM)中删除,并生成新的服务密钥,以改用仅存储在用户设备上的密钥来加密云端数据support.apple.comsupport.apple.com。这一过程确保全局 DEK(即各服务的新密钥)仅存在于用户受信设备上,苹果服务器端不再持有其副本。
是否变化及何时变化:在正常使用中,全局 DEK(各服务密钥)的私钥一经生成会保持稳定,用于持续加密解密用户数据,并不会频繁更换。唯有在特定事件下才会轮换或更新密钥,例如用户启用高级数据保护时系统触发的一次性密钥轮换,以及用户后来关闭高级数据保护或怀疑密钥泄露时的情况support.apple.com。苹果文档指出,当用户打开高级数据保护时,设备会启动异步密钥轮换操作,为此前存储于苹果服务器的每个服务创建新的服务密钥support.apple.com。新数据随后使用新密钥加密,旧密钥无法解密新数据support.apple.com。同样地,当用户关闭高级数据保护返回标准保护时,设备会将原本仅存于本地的新密钥上传回苹果HSM,并可恢复使用先前的旧密钥support.apple.com。因此,可以总结:初始启用高级保护时会生成并切换到新的全局 DEK,此后这些密钥保持不变;如用户关闭功能则恢复旧密钥;除非再次启用或发生安全事件,系统通常不会主动更换全局 DEK。
值得注意的是,在极端情况下如果用户怀疑密钥泄露或设备失窃,用户可以选择通过重置整个端到端加密环境(例如先关闭再重新开启高级数据保护)来触发新的 DEK 生成,从而保护云端数据安全。然而,此操作会要求所有设备重新加入信任链,并重新上传数据副本加密后存储。
多设备环境下 DEK 的分发与封装
信任链机制: 苹果使用 iCloud 钥匙串的信任链(又称同步圈,circle of trust)来在多设备间安全同步全局 DEK。启用了高级数据保护后,属于用户 Apple ID 的所有受信设备共同构成一个加密信任链,每台设备都有一对用于同步的非对称椭圆曲线密钥(如 P-384)support.apple.com。当第一台设备生成全局 DEK 后,它会将这些密钥加入自身的 iCloud 钥匙串保护域,并通过 CloudKit 安全地共享给用户的其他设备support.apple.com。具体而言,设备会维护一份受信设备的公钥列表,并使用自身的私钥对列表签名后存储于 iCloud;只有持有用户账户密码或设备私钥者才能读取或篡改这份列表support.apple.com。这一机制保证了只有经过用户授权加入信任链的设备才能获取 DEK,其余任何第三方(包括苹果服务器)都无法读取信任链中的密钥数据support.apple.com。
密钥传递与封装:在多设备场景下,每台设备都会持有全局 DEK(各服务私钥)的一个副本,但这些副本始终以安全加密形式封装后再传输和存储。例如,当用户新增一台受信设备时,新设备会生成自己的同步密钥对并向云端发出加入信任链的请求support.apple.com。已有的一台受信设备(通常是用户主动在其上同意新增设备)会验证该请求并通过 设备间安全信道 传输 DEK 副本给新设备support.apple.com。在此过程中,现有设备会利用新设备的公钥来加密封装 DEK,或双方通过椭圆曲线 Diffie-Hellman(ECDH)协商会话密钥来传递 DEK,从而确保只有目标新设备能解开密钥包装。苹果未公开具体用哪种算法封装,但业界常用方案包括 AES 密钥封装算法(AES-KW) 或 AES-GCM 算法 对会话密钥加密support.apple.comsupport.apple.com。可以推测,Apple 采用了符合 NIST 标准的 AES-256 算法对对称 DEK 进行二次加密包装,并结合设备的非对称密钥进行密钥交换/加密,以实现端到端的安全传递。
本地存储与保护:当设备接收到封装的 DEK 后,会在本地将其解密并安全保存于设备的 Keychain 中。所有 DEK 私钥仅存在于设备的安全隔区中,例如 iPhone 的密钥保存在 Data Protection 类钥匙串项下,并受 Secure Enclave 协处理器保护(访问需通过用户设备解锁)support.apple.com。这样设计保证即使设备遗失或被攻破,未解锁状态下设备上的 DEK 依然难以提取。总之,多设备环境下,每台受信设备都持有全局 DEK 副本,但始终通过端到端加密的方式同步与存储:传输过程中使用公钥加密/会话密钥,存储时依赖设备硬件密钥封装技术(如 Secure Enclave 提供的UID派生密钥)进一步加密,最大程度降低密钥泄露风险。
设备新增、移除与丢失场景下 DEK 和数据的生命周期
新设备加入: 当用户在新设备上登入 iCloud 并启用高级数据保护时,该设备无法直接访问云端受保护数据,需要首先加入信任链。加入流程包括:新设备生成自己的同步密钥对并将公钥提交给苹果云端(CloudKit)support.apple.com;苹果服务器将此请求传达给用户已有的一台受信设备上,提醒用户有新设备申请加入。用户在已有设备上批准请求(需输入密码或通过生物识别验证身份),之后已有设备会将新设备的公钥添加到信任链并再次用自己的私钥和账户密码派生密钥签署信任圈数据support.apple.com。随后,该已有设备通过上述安全信道,将全局 DEK 的加密副本传送给新设备support.apple.com。一旦新设备成功解密获得 DEK,它就加入了受信设备列表,可以像其他设备一样解密云端的端到端加密数据。整个过程确保只有获得用户明示批准的新设备才能获取 DEK support.apple.com。
设备移除与更换:当用户从 Apple ID 中移除某台设备,或设备被抹除/重置时,该设备将不再被视为信任链的一员。此时其他仍在线的受信设备会更新信任链状态,将该设备的身份从受信列表中剔除support.apple.com。需要强调的是,移除设备本身并不会导致全局 DEK 自动更改。被移除的设备虽曾持有 DEK 副本,但一旦不再受信,其无法从苹果服务器获取新的数据更新,而且由于设备已从账户移除或被抹掉,攻击者无法再借此解密云端后续的数据。苹果并未设定在每次设备变动时轮换密钥,这是出于实用性的考虑——频繁更换 DEK 将要求对云端大量数据重新加密,代价高昂。不过,若某台设备遗失且用户怀疑其本地密钥可能泄露,用户可以选择手动采取措施,例如从 iCloud 设置中移除此设备并重置高级数据保护(关闭再开启),从而生成新的 DEK,保护未来的数据安全。
云端数据影响: 当设备移除或失效时,云端已经加密的数据依旧由原来的 DEK 保护,并不会因为设备离开而重新加密。只要用户其他任一受信设备仍保存着该 DEK,便可继续访问此前的数据。被移除的设备由于缺失信任凭证,也无法再从服务器同步到后续新增或修改的任何机密数据(即使攻击者拥有其物理设备,由于密钥受 Secure Enclave 和设备密码保护,也难以提取support.apple.com)。因此,在多设备环境中,云端数据的可访问性取决于至少有一台受信设备存有对应 DEK。只要用户至少有一台设备或有效的恢复方式,数据就可解密使用;反之则数据陷于加密状态无法读取。
失去所有设备:高级数据保护要求用户在失去所有受信设备的极端情况下,借助预先设置的恢复机制取回 DEK。苹果强制要求启用该功能的用户提供至少一种账户恢复方法(例如指定恢复联系人或设置恢复密钥)support.apple.comsupport.apple.com。当用户所有设备均遗失或不可用时,只有通过这些恢复方式才能重获对数据的访问权。具体而言,如果用户提前设置了恢复密钥(一串随机生成的28位字符)并安全保存,那么此时用户可在新设备上登陆 Apple ID,并输入该恢复密钥来恢复数据。苹果服务器会将一份加密的 DEK 备份( escrow 记录 )下发到新设备,而新设备利用用户提供的恢复密钥将其解密,提取出全局 DEKsupport.apple.comsupport.apple.com。由于恢复密钥是由用户掌控、苹果不存储明文的要素,只有提供正确密钥的新设备才能解开 escrow 获得 DEK。在成功恢复后,新设备将重建信任链,并可以访问之前端到端加密的所有云端数据。
若用户选择的是恢复联系人,流程类似:用户联系预先设定的可信联系人,由联系人通过其苹果设备生成一个验证代码提供给用户。用户在新设备上输入该代码后,苹果同样将加密的 DEK 备份下发,新设备据此恢复密钥。整个恢复流程依然遵循端到端加密原则:苹果仅充当中转并验证权限,但并不知晓用户的实际 DEK 内容support.apple.com。
不可恢复的情况:如果用户既没有其他受信设备、又未设置任何恢复联系人或恢复密钥,那么全局 DEK 将无法找回,相应的云端数据也就永久处于加密不可读状态support.apple.com。苹果明确表示,若用户丢失所有设备且无恢复方式,公司无法帮助用户恢复这部分端到端加密的数据support.apple.com。这凸显了高级数据保护的一个权衡:安全性增强的同时,数据恢复的责任完全由用户自担。因此用户需谨慎管理受信设备和恢复选项,以避免陷入无法解密个人数据的境地。
DEK 安全性的密码学保障机制
苹果在高级数据保护与 iCloud 钥匙串架构中运用了多种密码学机制来保障 DEK 的机密性和完整性,包括密钥封装、密钥派生、硬件安全模块,以及严格的权限控制:
-
端到端加密与密钥层级化:如上所述,iCloud 采用分层密钥架构对数据加密。以 CloudKit 私有数据库为例,每位用户有一个顶层的 CloudKit 服务密钥对,其私钥用来保护下层对称密钥(如 Zone密钥、Record记录密钥等)
support.apple.com。当用户在设备上写入数据时,会生成记录级别的随机对称密钥加密数据字段,再逐层用上级密钥封装这些对称密钥。具体来说,记录密钥用 Zone 密钥加密,Zone 密钥再用全局服务公钥加密(即 DEK 公钥),形成多层密钥封装结构support.apple.com。只有持有最顶层私钥(DEK 私钥)的受信设备才能逐层解开封装,最终解密出用户数据。通过这种分层加密与密钥隔离设计,即使某一层的密钥泄露,攻击者也无法直接获取上层密钥或明文数据。
-
AES 密钥封装与封闭式硬件存储:苹果广泛采用了经验证的对称加密算法来封装和存储 DEK。传输过程中的 DEK(或下层对称密钥)通常通过 AES-256 算法加密封装后再上传support.apple.com。一种常用方法是 AES 密钥包装 (AES-KW),它专门用于用一个对称密钥安全地封装另一个密钥,确保密钥材料在传输中不暴露。与此同时,设备本地的 DEK 私钥会存储在受 Secure Enclave 保护的区域。Secure Enclave 为每台设备提供唯一的硬件 UID 密钥,仅用于解锁设备密钥袋和钥匙串项support.apple.com。也就是说, DEK 私钥本身可能被进一步用设备硬件密钥加密(这相当于在软件密钥之外又加了一道硬件锁)。只有当用户解锁设备并通过身份验证,操作系统才能调用 Secure Enclave 解封这些密钥用于加解密操作。通过AES-GCM 等对称加密结合Secure Enclave 硬件密钥封装,苹果确保 DEK 无论在云端传输还是本地存储,都始终处于加密状态,降低被截获或提取的风险support.apple.com。
-
椭圆曲线密码与密钥交换: 信任链中设备互认和密钥共享依赖椭圆曲线密码算法。每台设备的同步身份密钥对采用强大的 P-256 或 P-384 曲线support.apple.comsupport.apple.com。当新设备加入时,已有设备会利用椭圆曲线数字签名算法 (ECDSA) 对信任链数据签名校验,防止伪造support.apple.com。同时,在设备间传输 DEK 时,可能使用椭圆曲线 Diffie-Hellman (ECDH) 来建立共享密钥,加密传输内容。ECDH 可确保即使通信被窃听,攻击者无法推导出会话密钥,因而无法获取密钥内容。综上,非对称加密和密钥交换协议保证了只有合法设备才能参与密钥同步,新设备的引入需要现有设备用其私钥签名确认,杜绝中间人攻击或伪造信任链的可能。
-
密钥派生函数 (KDF):在某些步骤中,苹果使用了密钥派生函数强化密码。历史上,iCloud 钥匙串曾要求用户设置 iCloud 安全码时,将用户密码通过 PBKDF2 等KDF算法派生出密钥,用于签名和加密信任圈hackmag.comhackmag.com。即便在新的双重认证架构下,某些场景仍可能涉及KDF——例如恢复密钥或联系人代码很可能通过 KDF 转换为实际用于解密 escrow 密文的密钥材料。这些 KDF 算法引入高强度的盐值和大量迭代运算hackmag.com,增强了抗暴力破解能力,防止弱口令被攻击者猜测。总之,KDF 的应用确保从用户口令/恢复码到加密密钥的映射具有单向性和计算复杂度,进一步保护 DEK 相关流程的安全。
服务器无权获取明文 DEK 的保障
苹果的设计宗旨是在云端架起“盲墙”,确保服务器既无权也无实能接触用户 DEK 的明文,这也是实现“即使云端泄露,用户数据仍安全”的关键:
-
密钥仅存在于用户端: 开启高级数据保护后,所有主要 iCloud 数据类别的加密密钥仅存储于用户受信设备(或用户掌握的恢复载体)中,苹果服务器端不再保存这些密钥support.apple.com。文档明确指出,启用该功能后,苹果“无法读取或访问用户的服务密钥”support.apple.com。即在正常运行过程中,苹果的云服务器从未拥有解锁用户端到端加密数据所需的密钥。服务器所见到的只是由用户设备加密后的数据碎片,对其而言是不可解密的黑箱。
-
云端存储密文及加密元数据:iCloud 服务器虽然需要存储用户数据(如云照片、备忘录的加密内容),但这些内容均已由设备使用 DEK 加密完成。即便是为了提供某些功能,云端保留了少量未加密的元数据(如文件校验和用于重复数据消除),这些元数据也不包含可用于推导 DEK 的信息support.apple.comsupport.apple.com。苹果正在致力于将更多此类元数据也纳入端到端加密范围,以进一步减少明文暴露面support.apple.com。此外,CloudKit 框架要求开发者在模式中明确标记需要加密的字段,未标记的字段(例如排序用的时间戳)即便明文存储,亦不涉及敏感内容support.apple.com。由此,云服务器始终缺乏关于 DEK 或用户敏感数据的明文,一旦发生数据泄露或内部越权,攻击者拿到的也只是高强度加密下的乱码。
-
权限架构防范后门访问:苹果构建的信任链机制也防止了服务器假借授权来获取密钥的可能性。服务器不能私自添加受信设备或篡改信任链,因为每次信任链更新都需要现有设备的私钥签名以及(在老架构下)用户密码派生密钥的二次签名hackmag.comsupport.apple.com。苹果服务器既不持有用户设备私钥,也不知晓用户密码,因此无法伪造这些签名来诱导其他设备信任一个恶意设备。即使在双重认证体系下,服务器在设备加入流程中充当中继,并没有能力绕过用户批准直接将新设备植入圈内support.apple.comsupport.apple.com。这种架构等于为服务器访问用户密钥设置了密码学上的禁区。正如苹果安全白皮书所言,在最坏情形下如果用户丢失对 iCloud 钥匙串和其恢复机制的访问,那么相应的端到端加密数据苹果也无力恢复support.apple.com。苹果通过制度和技术结合,确保即便政府或机构要求提供用户数据,由于公司本身并无解密能力,只能交出加密的内容。
综上所述,Apple 高级数据保护下,全局数据加密密钥的生成由用户设备掌控,借助 iCloud 钥匙串信任链在多设备间安全同步。无论是在设备增加、移除还是用户失去设备的情况下,密钥和数据的生命周期管理均以用户掌控为中心:只要用户保有至少一个密钥载体(设备或恢复方式),数据即可解密使用;反之苹果也无法绕过用户获取密钥明文support.apple.com。苹果通过成熟的加密算法(AES-KW、ECDH 等)、硬件支持(Secure Enclave)、密钥分层与派生策略,实现了“零信任”云存储:服务器对用户密钥一无所知,从而使用户云端数据获得前所未有的保密性提升。

2025-05-14 05:56:15Shanghai: Bus Stops Here
A new crowd-sourced transit platform allows riders to propose, vote on, and activate new bus lines in as little as three days.
From early-morning school drop-offs to seniors booking rides to the hospital, from suburban commuters seeking a faster link to the metro to families visiting ancestral graves, Shanghai is rolling out a new kind of public bus — one that’s designed by commuters, and launched only when enough riders request it.
Branded “DZ” for dingzhi, or “customized,” the system invites residents to submit proposed routes through a city-run platform. Others with similar travel needs can opt in or vote, and if demand meets the threshold — typically 15 to 20 passengers per trip — the route goes live.
More than 220 DZ routes have already launched across all 16 city districts. Through an online platform opened May 8, users enter start and end points, preferred times, and trip frequency. If approved, routes can begin running in as little as three days.

2025-02-04 08:29:00President Trump has started rolling out his tariffs, something I blogged about in November. People are talking about these tariffs a lot right now, with many people (correctly) commenting on how consumers will end up with higher prices as a result of these tariffs. While that part is true, I’ve seen a lot of people taking it to the next, incorrect step: that consumers will pay the entirety of the tax. I put up a poll on X to see what people thought, and while the right answer got a lot of votes, it wasn't the winner.
For purposes of this blog post, our ultimate question will be the following:
- Suppose apples currently sell for $1 each in the entire United States.
- There are domestic sellers and foreign sellers of apples, all receiving the same price.
- There are no taxes or tariffs on the purchase of apples.
- The question is: if the US federal government puts a $0.50 import tariff per apple, what will be the change in the following:
- Number of apples bought in the US
- Price paid by buyers for apples in the US
- Post-tax price received by domestic apple producers
- Post-tax price received by foreign apple producers
Before we can answer that question, we need to ask an easier, first question: before instituting the tariff, why do apples cost $1?
And finally, before we dive into the details, let me provide you with the answers to the ultimate question. I recommend you try to guess these answers before reading this, and if you get it wrong, try to understand why:
- The number of apples bought will go down
- The buyers will pay more for each apple they buy, but not the full amount of the tariff
- Domestic apple sellers will receive a higher price per apple
- Foreign apple sellers will receive a lower price per apple, but not lowered by the full amount of the tariff
In other words, regardless of who sends the payment to the government, both taxed parties (domestic buyers and foreign sellers) will absorb some of the costs of the tariff, while domestic sellers will benefit from the protectionism provided by tariffs and be able to sell at a higher price per unit.
Marginal benefit
All of the numbers discussed below are part of a helper Google Sheet I put together for this analysis. Also, apologies about the jagged lines in the charts below, I hadn’t realized before starting on this that there are some difficulties with creating supply and demand charts in Google Sheets.
Let’s say I absolutely love apples, they’re my favorite food. How much would I be willing to pay for a single apple? You might say “$1, that’s the price in the supermarket,” and in many ways you’d be right. If I walk into supermarket A, see apples on sale for $50, and know that I can buy them at supermarket B for $1, I’ll almost certainly leave A and go buy at B.
But that’s not what I mean. What I mean is: how high would the price of apples have to go everywhere so that I’d no longer be willing to buy a single apple? This is a purely personal, subjective opinion. It’s impacted by how much money I have available, other expenses I need to cover, and how much I like apples. But let’s say the number is $5.
How much would I be willing to pay for another apple? Maybe another $5. But how much am I willing to pay for the 1,000th apple? 10,000th? At some point, I’ll get sick of apples, or run out of space to keep the apples, or not be able to eat, cook, and otherwise preserve all those apples before they rot.
The point being: I’ll be progressively willing to spend less and less money for each apple. This form of analysis is called marginal benefit: how much benefit (expressed as dollars I’m willing to spend) will I receive from each apple? This is a downward sloping function: for each additional apple I buy (quantity demanded), the price I’m willing to pay goes down. This is what gives my personal demand curve. And if we aggregate demand curves across all market participants (meaning: everyone interested in buying apples), we end up with something like this:
Assuming no changes in people’s behavior and other conditions in the market, this chart tells us how many apples will be purchased by our buyers at each price point between $0.50 and $5. And ceteris paribus (all else being equal), this will continue to be the demand curve for apples.
Marginal cost
Demand is half the story of economics. The other half is supply, or: how many apples will I sell at each price point? Supply curves are upward sloping: the higher the price, the more a person or company is willing and able to sell a product.
Let’s understand why. Suppose I have an apple orchard. It’s a large property right next to my house. With about 2 minutes of effort, I can walk out of my house, find the nearest tree, pick 5 apples off the tree, and call it a day. 5 apples for 2 minutes of effort is pretty good, right?
Yes, there was all the effort necessary to buy the land, and plant the trees, and water them… and a bunch more than I likely can’t even guess at. We’re going to ignore all of that for our analysis, because for short-term supply-and-demand movement, we can ignore these kinds of sunk costs. One other simplification: in reality, supply curves often start descending before ascending. This accounts for achieving efficiencies of scale after the first number of units purchased. But since both these topics are unneeded for understanding taxes, I won’t go any further.
Anyway, back to my apple orchard. If someone offers me $0.50 per apple, I can do 2 minutes of effort and get $2.50 in revenue, which equates to a $75/hour wage for me. I’m more than happy to pick apples at that price!
However, let’s say someone comes to buy 10,000 apples from me instead. I no longer just walk out to my nearest tree. I’m going to need to get in my truck, drive around, spend the day in the sun, pay for gas, take a day off of my day job (let’s say it pays me $70/hour). The costs go up significantly. Let’s say it takes 5 days to harvest all those apples myself, it costs me $100 in fuel and other expenses, and I lose out on my $70/hour job for 5 days. We end up with:
- Total expenditure: $100 + $70 * 8 hours a day * 5 days \== $2900
- Total revenue: $5000 (10,000 apples at $0.50 each)
- Total profit: $2100
So I’m still willing to sell the apples at this price, but it’s not as attractive as before. And as the number of apples purchased goes up, my costs keep increasing. I’ll need to spend more money on fuel to travel more of my property. At some point I won’t be able to do the work myself anymore, so I’ll need to pay others to work on the farm, and they’ll be slower at picking apples than me (less familiar with the property, less direct motivation, etc.). The point being: at some point, the number of apples can go high enough that the $0.50 price point no longer makes me any money.
This kind of analysis is called marginal cost. It refers to the additional amount of expenditure a seller has to spend in order to produce each additional unit of the good. Marginal costs go up as quantity sold goes up. And like demand curves, if you aggregate this data across all sellers, you get a supply curve like this:
Equilibrium price
We now know, for every price point, how many apples buyers will purchase, and how many apples sellers will sell. Now we find the equilibrium: where the supply and demand curves meet. This point represents where the marginal benefit a buyer would receive from the next buyer would be less than the cost it would take the next seller to make it. Let’s see it in a chart:
You’ll notice that these two graphs cross at the $1 price point, where 63 apples are both demanded (bought by consumers) and supplied (sold by producers). This is our equilibrium price. We also have a visualization of the surplus created by these trades. Everything to the left of the equilibrium point and between the supply and demand curves represents surplus: an area where someone is receiving something of more value than they give. For example:
- When I bought my first apple for $1, but I was willing to spend $5, I made $4 of consumer surplus. The consumer portion of the surplus is everything to the left of the equilibrium point, between the supply and demand curves, and above the equilibrium price point.
- When a seller sells his first apple for $1, but it only cost $0.50 to produce it, the seller made $0.50 of producer surplus. The producer portion of the surplus is everything to the left of the equilibrium point, between the supply and demand curves, and below the equilibrium price point.
Another way of thinking of surplus is “every time someone got a better price than they would have been willing to take.”
OK, with this in place, we now have enough information to figure out how to price in the tariff, which we’ll treat as a negative externality.
Modeling taxes
Alright, the government has now instituted a $0.50 tariff on every apple sold within the US by a foreign producer. We can generally model taxes by either increasing the marginal cost of each unit sold (shifting the supply curve up), or by decreasing the marginal benefit of each unit bought (shifting the demand curve down). In this case, since only some of the producers will pay the tax, it makes more sense to modify the supply curve.
First, let’s see what happens to the foreign seller-only supply curve when you add in the tariff:
With the tariff in place, for each quantity level, the price at which the seller will sell is $0.50 higher than before the tariff. That makes sense: if I was previously willing to sell my 82nd apple for $3, I would now need to charge $3.50 for that apple to cover the cost of the tariff. We see this as the tariff “pushing up” or “pushing left” the original supply curve.
We can add this new supply curve to our existing (unchanged) supply curve for domestic-only sellers, and we end up with a result like this:
The total supply curve adds up the individual foreign and domestic supply curves. At each price point, we add up the total quantity each group would be willing to sell to determine the total quantity supplied for each price point. Once we have that cumulative supply curve defined, we can produce an updated supply-and-demand chart including the tariff:
As we can see, the equilibrium has shifted:
- The equilibrium price paid by consumers has risen from $1 to $1.20.
- The total number of apples purchased has dropped from 63 apples to 60 apples.
- Consumers therefore received 3 less apples. They spent $72 for these 60 apples, whereas previously they spent $63 for 3 more apples, a definite decrease in consumer surplus.
- Foreign producers sold 36 of those apples (see the raw data in the linked Google Sheet), for a gross revenue of $43.20. However, they also need to pay the tariff to the US government, which accounts for $18, meaning they only receive $25.20 post-tariff. Previously, they sold 42 apples at $1 each with no tariff to be paid, meaning they took home $42.
- Domestic producers sold the remaining 24 apples at $1.20, giving them a revenue of $28.80. Since they don’t pay the tariff, they take home all of that money. By contrast, previously, they sold 21 apples at $1, for a take-home of $21.
- The government receives $0.50 for each of the 60 apples sold, or in other words receives $30 in revenue it wouldn’t have received otherwise.
We could be more specific about the surpluses, and calculate the actual areas for consumer surplus, producer surplus, inefficiency from the tariff, and government revenue from the tariff. But I won’t bother, as those calculations get slightly more involved. Instead, let’s just look at the aggregate outcomes:
- Consumers were unquestionably hurt. Their price paid went up by $0.20 per apple, and received less apples.
- Foreign producers were also hurt. Their price received went down from the original $1 to the new post-tariff price of $1.20, minus the $0.50 tariff. In other words: foreign producers only receive $0.70 per apple now. This hurt can be mitigated by shifting sales to other countries without a tariff, but the pain will exist regardless.
- Domestic producers scored. They can sell less apples and make more revenue doing it.
- And the government walked away with an extra $30.
Hopefully you now see the answer to the original questions. Importantly, while the government imposed a $0.50 tariff, neither side fully absorbed that cost. Consumers paid a bit more, foreign producers received a bit less. The exact details of how that tariff was split across the groups is mediated by the relevant supply and demand curves of each group. If you want to learn more about this, the relevant search term is “price elasticity,” or how much a group’s quantity supplied or demanded will change based on changes in the price.
Other taxes
Most taxes are some kind of a tax on trade. Tariffs on apples is an obvious one. But the same applies to income tax (taxing the worker for the trade of labor for money) or payroll tax (same thing, just taxing the employer instead). Interestingly, you can use the same model for analyzing things like tax incentives. For example, if the government decided to subsidize domestic apple production by giving the domestic producers a $0.50 bonus for each apple they sell, we would end up with a similar kind of analysis, except instead of the foreign supply curve shifting up, we’d see the domestic supply curve shifting down.
And generally speaking, this is what you’ll always see with government involvement in the economy. It will result in disrupting an existing equilibrium, letting the market readjust to a new equilibrium, and incentivization of some behavior, causing some people to benefit and others to lose out. We saw with the apple tariff, domestic producers and the government benefited while others lost.
You can see the reverse though with tax incentives. If I give a tax incentive of providing a deduction (not paying income tax) for preschool, we would end up with:
- Government needs to make up the difference in tax revenue, either by raising taxes on others or printing more money (leading to inflation). Either way, those paying the tax or those holding government debased currency will pay a price.
- Those people who don’t use the preschool deduction will receive no benefit, so they simply pay a cost.
- Those who do use the preschool deduction will end up paying less on tax+preschool than they would have otherwise.
This analysis is fully amoral. It’s not saying whether providing subsidized preschool is a good thing or not, it simply tells you where the costs will be felt, and points out that such government interference in free economic choice does result in inefficiencies in the system. Once you have that knowledge, you’re more well educated on making a decision about whether the costs of government intervention are worth the benefits.

2025-05-13 16:47:48(Textículo em prosa erudita sobre a Ideologia Anarco-Capitalista-Cristã)
https://davipinheiro.com/01-escravos-da-cara-inchada/
A cultura #Woke apropriou-se da imagem sobre a #escravidão. Quando uma pessoa aculturada imagina um #escravo, vem em sua mente a imagem de um ser humano negro, magro e flagelado. Para quem enxerga além das cortinas da mentira, vem em sua mente a imagem de um ser humano de qualquer etnia, gordo e doente.
Democracia, péssimo regime de governo assim classificado pelo seu próprio idealizador: Platão em A República, é o grito da hienas de dentes arreganhados para ampliação do regime escravocrata fomentado pelos #GlobalistasSatanistas.
Um escravo da cara inchada é todo aquele ser humano ignorante inconsciente que alimenta esse sistema em troca de intoxicantes como flúor¹, cloro, glutamato monosódico, gordura trans, corantes, conservantes, refrigerantes, bebidas alcoólicas, psicotrópicos e remédios sintomáticos, tudo embrulhado com mentiras reiteradas.
Como consequência, após os 18 anos de idade o corpo do #EscravoDaCaraInchada sucumbe à tamanha intoxicação e passa a inchar, sendo fisicamente perceptível sua condição de escravo da cara inchada tanto à olho nú quando por reconhecimento facial de qualquer pseudo inteligência artificial.
O círculo vicioso da #EscravidaoDemocratica é tão simples e tosco como o “pão e circo romano”, Mesmo assim é muito difícil para o escravo da cara inchada perceber a própria condição tamanha é sua intoxicação física e mental.
Se um Anarco-Capitalista-Cristão (#Ancapcristão) chega para um escravo da cara inchada e explica sobre esses intoxicantes como instrumento de escravização, dificilmente o escravo da cara inchada irá acreditar pois diferentemente do antigo e aposentado chicote, o novo instrumento da escravidão não dói de imediato e os próprios efeitos da intoxicação impedem-no de raciocinar com clareza.
Portanto, para que os #GlobalistasSatanistas obtivessem sucesso na democratização da escravidão, tiveram que criar um chicote químico e uma ideologia favorável. Quanto às etapas utilizadas para formação dessa ideologia no inconsciente coletivo passo a elencar as 6 grandes mentiras em ordem cronológica:
(1ª etapa) Iluminismo: distanciamento de #Deus e seus ensinamentos, criação de sociedades secretas, exacerbação do ser humano perante o criador na tentativa de projetar o ser humano como seu próprio deus, tornando-o responsável sobre os rumos naturais do planeta. Assim formou-se a base ideológica para o materialismo, ambientalismo, feminismo, controle populacional e ideologia de gêneros;
(2ª etapa) Materialismo: perda do propósito espiritual e do sentido da vida², o que passa a importar são apenas as coisas materiais, acima inclusive do próprio ser humano. A perpetuação da espécie também fica em segundo plano. Assim formou-se a base ideológica para o ambientalismo, feminismo, controle populacional e ideologia de gêneros;
(3ª etapa) Ambientalismo: redução do ser humano à mero câncer do planeta superlotado, atribuído-lhe a responsabilidade por qualquer desastre natural. Assim formou-se a base ideológica para o controle populacional e ideologia de gêneros;
(4ª etapa) Feminismo: enfraquecimento do ser humano por meio da sua divisão em duas categorias: macho e fêmea, os quais são inimigos e não cooperadores. A ideia de igualdade de gêneros é tão antagônica que beira ao conflito cognitivo³: Eles querem separar para dizer que são iguais... Ora, como não pode haver diferenças entre os gêneros se eles são fisicamente e mentalmente diferentes? Nesse diapasão, mesmo não sendo os estados nacionais os arquitetos da escravidão democrática e sim meros fantoches dos globalistas satanistas, o voto feminino foi fundamental para aprovação de leis misândricas com o fito de acelerar a destruição da base familiar do escravo da cara inchada. Importante mencionar que a base familiar dos globalistas satanistas continua sendo patriarcal. Assim formou-se a base ideológica para o controle populacional e ideologia de gêneros;
(5ª etapa) Controle Populacional: “Crescei e multiplicai-vos” é o caralho, Deus não sabe de nada (Iluminismo), o que importa é o dinheiro e filho é caro (Materialismo), para que colocar mais um ser humano nesse planeta doente e superlotado (Ambientalismo), além disso o sexo oposto é meu inimigo (Feminismo). Essa é base ideológica que antecede a ideologia de Controle Populacional, ainda reforçada pela apologia à castração, já que em todas as mídias produzidas com patrocínio oculto de capital globalista satanista tentam normalizar a castração do homem (perda da capacidade de reprodução) desde em desenhos infantis até grandes produções cinematográficas, ora em tom de humor ora em tom de tortura. Assim os escravos da cara inchada do sexo masculino perderam sua identidade, essência e desejo de ser o que são, formando-se a base ideológica para o homossexualismo, ou seja, para a ideologia de gêneros.
(6ª etapa) Ideologia de Gêneros: É a cereja do bolo para os planos do Diabo (Anjo invejoso de Deus que quer destruir a maior criação: nós). Enquanto os globalistas satanistas, dentro de sua sábia ignorância, acreditam estarem chefiando a democratização da escravidão, na verdade também não passam de meros fantoches do Anjo Caído. Com a sexta e última etapa de mentiras para extinção da humanidade (#apocalipse) posta em prática através da Ideologia de Gêneros, fecha-se o ciclo vicioso de mentiras que se auto justificam: Se #Deus não presta, o que vale são os bens materiais, o ser humano é um câncer no planeta, o sexo oposto é inimigo e ter filhos é uma péssima ideia e ser homem másculo é crime, então ser #homossexual é a melhor opção, inclusive vamos castrar os meninos antes da puberdade sem o consentimento dos pais ou mães solo. Aqui também há uma grande bifurcação do círculo vicioso de mentiras, qual seja o gritante conflito cognitivo³: Se todos os homens deixarem de ser másculos, quem vai comer os #gays afeminados? Ou se todas as mulheres deixarem de ser femininas, quem as #sapatonas irão comer? E o pior, se todos passem a ser homossexuais quem vai perpetuar a espécie? Seremos extintos no lapso temporal de apenas uma geração, pois a fraudulenta medicina moderna jamais terá a capacidade de gerar bebês de chocadeira à tempo.
É interessante enxergar que mesmo os Globalistas Satanistas, dentro de sua sábia ignorância, acreditando estarem democratizando a escravidão em benefício próprio, na verdade apenas estão fomentando o apocalipse, ou seja sua própria extinção. Também não terão qualquer lugar especial no inferno, sinônimo de mal é mentira. Portanto os #GlobalistaSatanistas são meros fantoches do #Diabo enganador, tão submissos quanto o Escravo da Cara Inchada…
Interessante também enxergar que o livre arbítrio é uma condição obrigatória para independência da criação (anjo e ser humano). Todos somos livres para escolher entre o bem e o mal, se iremos ser escravos de #Deus ou escravos do Diabo. Se assim não fosse, inexistiria criação pois seríamos mera extensão da consciência do #Criador, em outras palavras: para que exista uma criação, essa deve ter a capacidade de decisão de forma independente, o chamado livre arbítrio.
Com base nisso, temos que não cabe à nos fazer qualquer revolução, tudo está normal, a luta entre o bem e o mal sempre irá existir pois um não existe sem o outro. Nos cabe apenas escolher o lado. Nesse contexto, tenho a seguinte mensagem destinada à você para encerrar o presente Textículo Anarco-Capitalista-Cristão:
------ > Se você for um ANARCO-CAPITALISTA-CRISTÃO passe esta palavra à diante para que a verdade atinja o maior número de ignorantes inconscientes possível;
------ > Se você for um GLOBALISTA SATANISTA, vai viver sua vida, desfrutar da própria fortuna e pare de ser fantoche o Diabo, mentiram para você: não terá qualquer lugar especial quando morrer;
------ > Se você for um ESCRAVO DA CARA INCHADA e não entendeu o que eu disse, por favor me pergunte ou debata comigo, terei o prazer em lhe ajudar a enxergar a verdade. Pare de trabalhar por dinheiro fiduciário, passe a aceitar #Monero e #Bitcoin em troca do seu trabalho, pois isso é o único jeito de sermos financeiramente livres, se tiver alguma dúvida sobre #criptomoedas me pergunte e terei o prazer e ensinar. Se ainda assim você se recusa a enxergar a verdade exposta aqui, por favor aceite #Monero e #Bitcoin quando for dar o seu cú. Ou melhor, cometa suicídio, já que você é um câncer no planeta, salve a natureza.

@ 4ba8e86d:89d32de4
2025-05-19 22:33:46O que é Cwtch? Cwtch (/kʊtʃ/ - uma palavra galesa que pode ser traduzida aproximadamente como “um abraço que cria um lugar seguro”) é um protocolo de mensagens multipartidário descentralizado, que preserva a privacidade, que pode ser usado para construir aplicativos resistentes a metadados.
Como posso pronunciar Cwtch? Como "kutch", para rimar com "butch".
Descentralizado e Aberto : Não existe “serviço Cwtch” ou “rede Cwtch”. Os participantes do Cwtch podem hospedar seus próprios espaços seguros ou emprestar sua infraestrutura para outras pessoas que buscam um espaço seguro. O protocolo Cwtch é aberto e qualquer pessoa é livre para criar bots, serviços e interfaces de usuário e integrar e interagir com o Cwtch.
Preservação de privacidade : toda a comunicação no Cwtch é criptografada de ponta a ponta e ocorre nos serviços cebola Tor v3.
Resistente a metadados : O Cwtch foi projetado de forma que nenhuma informação seja trocada ou disponibilizada a ninguém sem seu consentimento explícito, incluindo mensagens durante a transmissão e metadados de protocolo
Uma breve história do bate-papo resistente a metadados Nos últimos anos, a conscientização pública sobre a necessidade e os benefícios das soluções criptografadas de ponta a ponta aumentou com aplicativos como Signal , Whatsapp e Wire. que agora fornecem aos usuários comunicações seguras.
No entanto, essas ferramentas exigem vários níveis de exposição de metadados para funcionar, e muitos desses metadados podem ser usados para obter detalhes sobre como e por que uma pessoa está usando uma ferramenta para se comunicar.
Uma ferramenta que buscou reduzir metadados é o Ricochet lançado pela primeira vez em 2014. Ricochet usou os serviços cebola Tor v2 para fornecer comunicação criptografada segura de ponta a ponta e para proteger os metadados das comunicações.
Não havia servidores centralizados que auxiliassem no roteamento das conversas do Ricochet. Ninguém além das partes envolvidas em uma conversa poderia saber que tal conversa está ocorrendo.
Ricochet tinha limitações; não havia suporte para vários dispositivos, nem existe um mecanismo para suportar a comunicação em grupo ou para um usuário enviar mensagens enquanto um contato está offline.
Isto tornou a adoção do Ricochet uma proposta difícil; mesmo aqueles em ambientes que seriam melhor atendidos pela resistência aos metadados, sem saber que ela existe.
Além disso, qualquer solução para comunicação descentralizada e resistente a metadados enfrenta problemas fundamentais quando se trata de eficiência, privacidade e segurança de grupo conforme definido pelo consenso e consistência da transcrição.
Alternativas modernas ao Ricochet incluem Briar , Zbay e Ricochet Refresh - cada ferramenta procura otimizar para um conjunto diferente de compensações, por exemplo, Briar procura permitir que as pessoas se comuniquem mesmo quando a infraestrutura de rede subjacente está inoperante, ao mesmo tempo que fornece resistência à vigilância de metadados.
O projeto Cwtch começou em 2017 como um protocolo de extensão para Ricochet, fornecendo conversas em grupo por meio de servidores não confiáveis, com o objetivo de permitir aplicativos descentralizados e resistentes a metadados como listas compartilhadas e quadros de avisos.
Uma versão alfa do Cwtch foi lançada em fevereiro de 2019 e, desde então, a equipe do Cwtch dirigida pela OPEN PRIVACY RESEARCH SOCIETY conduziu pesquisa e desenvolvimento em cwtch e nos protocolos, bibliotecas e espaços de problemas subjacentes.
Modelo de Risco.
Sabe-se que os metadados de comunicações são explorados por vários adversários para minar a segurança dos sistemas, para rastrear vítimas e para realizar análises de redes sociais em grande escala para alimentar a vigilância em massa. As ferramentas resistentes a metadados estão em sua infância e faltam pesquisas sobre a construção e a experiência do usuário de tais ferramentas.
https://nostrcheck.me/media/public/nostrcheck.me_9475702740746681051707662826.webp
O Cwtch foi originalmente concebido como uma extensão do protocolo Ricochet resistente a metadados para suportar comunicações assíncronas de grupos multiponto por meio do uso de infraestrutura anônima, descartável e não confiável.
Desde então, o Cwtch evoluiu para um protocolo próprio. Esta seção descreverá os vários riscos conhecidos que o Cwtch tenta mitigar e será fortemente referenciado no restante do documento ao discutir os vários subcomponentes da Arquitetura Cwtch.
Modelo de ameaça.
É importante identificar e compreender que os metadados são omnipresentes nos protocolos de comunicação; é de facto necessário que tais protocolos funcionem de forma eficiente e em escala. No entanto, as informações que são úteis para facilitar peers e servidores também são altamente relevantes para adversários que desejam explorar tais informações.
Para a definição do nosso problema, assumiremos que o conteúdo de uma comunicação é criptografado de tal forma que um adversário é praticamente incapaz de quebrá-lo veja tapir e cwtch para detalhes sobre a criptografia que usamos, e como tal nos concentraremos em o contexto para os metadados de comunicação.
Procuramos proteger os seguintes contextos de comunicação:
• Quem está envolvido em uma comunicação? Pode ser possível identificar pessoas ou simplesmente identificadores de dispositivos ou redes. Por exemplo, “esta comunicação envolve Alice, uma jornalista, e Bob, um funcionário público”.
• Onde estão os participantes da conversa? Por exemplo, “durante esta comunicação, Alice estava na França e Bob estava no Canadá”.
• Quando ocorreu uma conversa? O momento e a duração da comunicação podem revelar muito sobre a natureza de uma chamada, por exemplo, “Bob, um funcionário público, conversou com Alice ao telefone por uma hora ontem à noite. Esta é a primeira vez que eles se comunicam.” *Como a conversa foi mediada? O fato de uma conversa ter ocorrido por meio de um e-mail criptografado ou não criptografado pode fornecer informações úteis. Por exemplo, “Alice enviou um e-mail criptografado para Bob ontem, enquanto eles normalmente enviam apenas e-mails de texto simples um para o outro”.
• Sobre o que é a conversa? Mesmo que o conteúdo da comunicação seja criptografado, às vezes é possível derivar um contexto provável de uma conversa sem saber exatamente o que é dito, por exemplo, “uma pessoa ligou para uma pizzaria na hora do jantar” ou “alguém ligou para um número conhecido de linha direta de suicídio na hora do jantar”. 3 horas da manhã."
Além das conversas individuais, também procuramos defender-nos contra ataques de correlação de contexto, através dos quais múltiplas conversas são analisadas para obter informações de nível superior:
• Relacionamentos: Descobrir relações sociais entre um par de entidades analisando a frequência e a duração de suas comunicações durante um período de tempo. Por exemplo, Carol e Eve ligam uma para a outra todos os dias durante várias horas seguidas.
• Cliques: Descobrir relações sociais entre um grupo de entidades que interagem entre si. Por exemplo, Alice, Bob e Eva se comunicam entre si.
• Grupos vagamente conectados e indivíduos-ponte: descobrir grupos que se comunicam entre si através de intermediários, analisando cadeias de comunicação (por exemplo, toda vez que Alice fala com Bob, ela fala com Carol quase imediatamente depois; Bob e Carol nunca se comunicam).
• Padrão de Vida: Descobrir quais comunicações são cíclicas e previsíveis. Por exemplo, Alice liga para Eve toda segunda-feira à noite por cerca de uma hora. Ataques Ativos
Ataques de deturpação.
O Cwtch não fornece registro global de nomes de exibição e, como tal, as pessoas que usam o Cwtch são mais vulneráveis a ataques baseados em declarações falsas, ou seja, pessoas que fingem ser outras pessoas:
O fluxo básico de um desses ataques é o seguinte, embora também existam outros fluxos:
•Alice tem um amigo chamado Bob e outro chamado Eve
• Eve descobre que Alice tem um amigo chamado Bob
• Eve cria milhares de novas contas para encontrar uma que tenha uma imagem/chave pública semelhante à de Bob (não será idêntica, mas pode enganar alguém por alguns minutos)
• Eve chama essa nova conta de "Eve New Account" e adiciona Alice como amiga.
• Eve então muda seu nome em "Eve New Account" para "Bob"
• Alice envia mensagens destinadas a "Bob" para a conta falsa de Bob de Eve Como os ataques de declarações falsas são inerentemente uma questão de confiança e verificação, a única maneira absoluta de evitá-los é os usuários validarem absolutamente a chave pública. Obviamente, isso não é o ideal e, em muitos casos, simplesmente não acontecerá .
Como tal, pretendemos fornecer algumas dicas de experiência do usuário na interface do usuário para orientar as pessoas na tomada de decisões sobre confiar em contas e/ou distinguir contas que possam estar tentando se representar como outros usuários.
Uma nota sobre ataques físicos A Cwtch não considera ataques que exijam acesso físico (ou equivalente) à máquina do usuário como praticamente defensáveis. No entanto, no interesse de uma boa engenharia de segurança, ao longo deste documento ainda nos referiremos a ataques ou condições que exigem tal privilégio e indicaremos onde quaisquer mitigações que implementámos falharão.
Um perfil Cwtch.
Os usuários podem criar um ou mais perfis Cwtch. Cada perfil gera um par de chaves ed25519 aleatório compatível com Tor.
Além do material criptográfico, um perfil também contém uma lista de Contatos (outras chaves públicas do perfil Cwtch + dados associados sobre esse perfil, como apelido e (opcionalmente) mensagens históricas), uma lista de Grupos (contendo o material criptográfico do grupo, além de outros dados associados, como apelido do grupo e mensagens históricas).
Conversões entre duas partes: ponto a ponto
https://nostrcheck.me/media/public/nostrcheck.me_2186338207587396891707662879.webp
Para que duas partes participem de uma conversa ponto a ponto, ambas devem estar on-line, mas apenas uma precisa estar acessível por meio do serviço Onion. Por uma questão de clareza, muitas vezes rotulamos uma parte como “ponto de entrada” (aquele que hospeda o serviço cebola) e a outra parte como “ponto de saída” (aquele que se conecta ao serviço cebola).
Após a conexão, ambas as partes adotam um protocolo de autenticação que:
• Afirma que cada parte tem acesso à chave privada associada à sua identidade pública.
• Gera uma chave de sessão efêmera usada para criptografar todas as comunicações futuras durante a sessão.
Esta troca (documentada com mais detalhes no protocolo de autenticação ) é negável offline , ou seja, é possível para qualquer parte falsificar transcrições desta troca de protocolo após o fato e, como tal - após o fato - é impossível provar definitivamente que a troca aconteceu de forma alguma.
Após o protocolo de autenticação, as duas partes podem trocar mensagens livremente.
Conversas em Grupo e Comunicação Ponto a Servidor
Ao iniciar uma conversa em grupo, é gerada uma chave aleatória para o grupo, conhecida como Group Key. Todas as comunicações do grupo são criptografadas usando esta chave. Além disso, o criador do grupo escolhe um servidor Cwtch para hospedar o grupo. Um convite é gerado, incluindo o Group Key, o servidor do grupo e a chave do grupo, para ser enviado aos potenciais membros.
Para enviar uma mensagem ao grupo, um perfil se conecta ao servidor do grupo e criptografa a mensagem usando a Group Key, gerando também uma assinatura sobre o Group ID, o servidor do grupo e a mensagem. Para receber mensagens do grupo, um perfil se conecta ao servidor e baixa as mensagens, tentando descriptografá-las usando a Group Key e verificando a assinatura.
Detalhamento do Ecossistema de Componentes
O Cwtch é composto por várias bibliotecas de componentes menores, cada uma desempenhando um papel específico. Algumas dessas bibliotecas incluem:
- abertoprivacidade/conectividade: Abstração de rede ACN, atualmente suportando apenas Tor.
- cwtch.im/tapir: Biblioteca para construção de aplicativos p2p em sistemas de comunicação anônimos.
- cwtch.im/cwtch: Biblioteca principal para implementação do protocolo/sistema Cwtch.
- cwtch.im/libcwtch-go: Fornece ligações C para Cwtch para uso em implementações de UI.
TAPIR: Uma Visão Detalhada
Projetado para substituir os antigos canais de ricochete baseados em protobuf, o Tapir fornece uma estrutura para a construção de aplicativos anônimos.
Está dividido em várias camadas:
• Identidade - Um par de chaves ed25519, necessário para estabelecer um serviço cebola Tor v3 e usado para manter uma identidade criptográfica consistente para um par.
• Conexões – O protocolo de rede bruto que conecta dois pares. Até agora, as conexões são definidas apenas através do Tor v3 Onion Services.
• Aplicativos - As diversas lógicas que permitem um determinado fluxo de informações em uma conexão. Os exemplos incluem transcrições criptográficas compartilhadas, autenticação, proteção contra spam e serviços baseados em tokens. Os aplicativos fornecem recursos que podem ser referenciados por outros aplicativos para determinar se um determinado peer tem a capacidade de usar um determinado aplicativo hospedado.
• Pilhas de aplicativos - Um mecanismo para conectar mais de um aplicativo, por exemplo, a autenticação depende de uma transcrição criptográfica compartilhada e o aplicativo peer cwtch principal é baseado no aplicativo de autenticação.
Identidade.
Um par de chaves ed25519, necessário para estabelecer um serviço cebola Tor v3 e usado para manter uma identidade criptográfica consistente para um peer.
InitializeIdentity - de um par de chaves conhecido e persistente:i,I
InitializeEphemeralIdentity - de um par de chaves aleatório: ie,Ie
Aplicativos de transcrição.
Inicializa uma transcrição criptográfica baseada em Merlin que pode ser usada como base de protocolos baseados em compromisso de nível superior
O aplicativo de transcrição entrará em pânico se um aplicativo tentar substituir uma transcrição existente por uma nova (aplicando a regra de que uma sessão é baseada em uma e apenas uma transcrição).
Merlin é uma construção de transcrição baseada em STROBE para provas de conhecimento zero. Ele automatiza a transformação Fiat-Shamir, para que, usando Merlin, protocolos não interativos possam ser implementados como se fossem interativos.
Isto é significativamente mais fácil e menos sujeito a erros do que realizar a transformação manualmente e, além disso, também fornece suporte natural para:
• protocolos multi-round com fases alternadas de commit e desafio;
• separação natural de domínios, garantindo que os desafios estejam vinculados às afirmações a serem provadas;
• enquadramento automático de mensagens, evitando codificação ambígua de dados de compromisso;
• e composição do protocolo, usando uma transcrição comum para vários protocolos.
Finalmente, o Merlin também fornece um gerador de números aleatórios baseado em transcrição como defesa profunda contra ataques de entropia ruim (como reutilização de nonce ou preconceito em muitas provas). Este RNG fornece aleatoriedade sintética derivada de toda a transcrição pública, bem como dos dados da testemunha do provador e uma entrada auxiliar de um RNG externo.
Conectividade Cwtch faz uso do Tor Onion Services (v3) para todas as comunicações entre nós.
Fornecemos o pacote openprivacy/connectivity para gerenciar o daemon Tor e configurar e desmontar serviços cebola através do Tor.
Criptografia e armazenamento de perfil.
Os perfis são armazenados localmente no disco e criptografados usando uma chave derivada de uma senha conhecida pelo usuário (via pbkdf2).
Observe que, uma vez criptografado e armazenado em disco, a única maneira de recuperar um perfil é recuperando a senha - como tal, não é possível fornecer uma lista completa de perfis aos quais um usuário pode ter acesso até inserir uma senha.
Perfis não criptografados e a senha padrão Para lidar com perfis "não criptografados" (ou seja, que não exigem senha para serem abertos), atualmente criamos um perfil com uma senha codificada de fato .
Isso não é o ideal, preferiríamos confiar no material de chave fornecido pelo sistema operacional, de modo que o perfil fosse vinculado a um dispositivo específico, mas esses recursos são atualmente uma colcha de retalhos - também notamos, ao criar um perfil não criptografado, pessoas que usam Cwtch estão explicitamente optando pelo risco de que alguém com acesso ao sistema de arquivos possa descriptografar seu perfil.
Vulnerabilidades Relacionadas a Imagens e Entrada de Dados
Imagens Maliciosas
O Cwtch enfrenta desafios na renderização de imagens, com o Flutter utilizando Skia, embora o código subjacente não seja totalmente seguro para a memória.
Realizamos testes de fuzzing nos componentes Cwtch e encontramos um bug de travamento causado por um arquivo GIF malformado, levando a falhas no kernel. Para mitigar isso, adotamos a política de sempre habilitar cacheWidth e/ou cacheHeight máximo para widgets de imagem.
Identificamos o risco de imagens maliciosas serem renderizadas de forma diferente em diferentes plataformas, como evidenciado por um bug no analisador PNG da Apple.
Riscos de Entrada de Dados
Um risco significativo é a interceptação de conteúdo ou metadados por meio de um Input Method Editor (IME) em dispositivos móveis. Mesmo aplicativos IME padrão podem expor dados por meio de sincronização na nuvem, tradução online ou dicionários pessoais.
Implementamos medidas de mitigação, como enableIMEPersonalizedLearning: false no Cwtch 1.2, mas a solução completa requer ações em nível de sistema operacional e é um desafio contínuo para a segurança móvel.
Servidor Cwtch.
O objetivo do protocolo Cwtch é permitir a comunicação em grupo através de infraestrutura não confiável .
Ao contrário dos esquemas baseados em retransmissão, onde os grupos atribuem um líder, um conjunto de líderes ou um servidor confiável de terceiros para garantir que cada membro do grupo possa enviar e receber mensagens em tempo hábil (mesmo que os membros estejam offline) - infraestrutura não confiável tem o objetivo de realizar essas propriedades sem a suposição de confiança.
O artigo original do Cwtch definia um conjunto de propriedades que se esperava que os servidores Cwtch fornecessem:
• O Cwtch Server pode ser usado por vários grupos ou apenas um.
• Um servidor Cwtch, sem a colaboração de um membro do grupo, nunca deve aprender a identidade dos participantes de um grupo.
• Um servidor Cwtch nunca deve aprender o conteúdo de qualquer comunicação.
• Um servidor Cwtch nunca deve ser capaz de distinguir mensagens como pertencentes a um grupo específico. Observamos aqui que essas propriedades são um superconjunto dos objetivos de design das estruturas de Recuperação de Informações Privadas.
Melhorias na Eficiência e Segurança
Eficiência do Protocolo
Atualmente, apenas um protocolo conhecido, o PIR ingênuo, atende às propriedades desejadas para garantir a privacidade na comunicação do grupo Cwtch. Este método tem um impacto direto na eficiência da largura de banda, especialmente para usuários em dispositivos móveis. Em resposta a isso, estamos ativamente desenvolvendo novos protocolos que permitem negociar garantias de privacidade e eficiência de maneiras diversas.
Os servidores, no momento desta escrita, permitem o download completo de todas as mensagens armazenadas, bem como uma solicitação para baixar mensagens específicas a partir de uma determinada mensagem. Quando os pares ingressam em um grupo em um novo servidor, eles baixam todas as mensagens do servidor inicialmente e, posteriormente, apenas as mensagens novas.
Mitigação de Análise de Metadados
Essa abordagem permite uma análise moderada de metadados, pois o servidor pode enviar novas mensagens para cada perfil suspeito exclusivo e usar essas assinaturas de mensagens exclusivas para rastrear sessões ao longo do tempo. Essa preocupação é mitigada por dois fatores:
- Os perfis podem atualizar suas conexões a qualquer momento, resultando em uma nova sessão do servidor.
- Os perfis podem ser "ressincronizados" de um servidor a qualquer momento, resultando em uma nova chamada para baixar todas as mensagens. Isso é comumente usado para buscar mensagens antigas de um grupo.
Embora essas medidas imponham limites ao que o servidor pode inferir, ainda não podemos garantir resistência total aos metadados. Para soluções futuras para esse problema, consulte Niwl.
Proteção contra Pares Maliciosos
Os servidores enfrentam o risco de spam gerado por pares, representando uma ameaça significativa à eficácia do sistema Cwtch. Embora tenhamos implementado um mecanismo de proteção contra spam no protótipo do Cwtch, exigindo que os pares realizem alguma prova de trabalho especificada pelo servidor, reconhecemos que essa não é uma solução robusta na presença de um adversário determinado com recursos significativos.
Pacotes de Chaves
Os servidores Cwtch se identificam por meio de pacotes de chaves assinados, contendo uma lista de chaves necessárias para garantir a segurança e resistência aos metadados na comunicação do grupo Cwtch. Esses pacotes de chaves geralmente incluem três chaves: uma chave pública do serviço Tor v3 Onion para o Token Board, uma chave pública do Tor v3 Onion Service para o Token Service e uma chave pública do Privacy Pass.
Para verificar os pacotes de chaves, os perfis que os importam do servidor utilizam o algoritmo trust-on-first-use (TOFU), verificando a assinatura anexada e a existência de todos os tipos de chave. Se o perfil já tiver importado o pacote de chaves do servidor anteriormente, todas as chaves são consideradas iguais.
Configuração prévia do aplicativo para ativar o Relé do Cwtch.
No Android, a hospedagem de servidor não está habilitada, pois essa opção não está disponível devido às limitações dos dispositivos Android. Essa funcionalidade está reservada apenas para servidores hospedados em desktops.
No Android, a única forma direta de importar uma chave de servidor é através do grupo de teste Cwtch, garantindo assim acesso ao servidor Cwtch.
Primeiro passo é Habilitar a opção de grupo no Cwtch que está em fase de testes. Clique na opção no canto superior direito da tela de configuração e pressione o botão para acessar as configurações do Cwtch.
Você pode alterar o idioma para Português do Brasil.Depois, role para baixo e selecione a opção para ativar os experimentos. Em seguida, ative a opção para habilitar o chat em grupo e a pré-visualização de imagens e fotos de perfil, permitindo que você troque sua foto de perfil.

O próximo passo é adicionar o FuzzBot, que é um bot de testes e de desenvolvimento.
Contato do FuzzBot: 4y2hxlxqzautabituedksnh2ulcgm2coqbure6wvfpg4gi2ci25ta5ad.
Ao enviar o comando "testgroup-invite" para o FuzzBot, você receberá um convite para entrar no Grupo Cwtch Test. Ao ingressar no grupo, você será automaticamente conectado ao servidor Cwtch. Você pode optar por sair do grupo a qualquer momento ou ficar para conversar e tirar dúvidas sobre o aplicativo e outros assuntos. Depois, você pode configurar seu próprio servidor Cwtch, o que é altamente recomendável. https://pomf2.lain.la/f/x4pm8hm8.mp4
Agora você pode utilizar o aplicativo normalmente. Algumas observações que notei: se houver demora na conexão com outra pessoa, ambas devem estar online. Se ainda assim a conexão não for estabelecida, basta clicar no ícone de reset do Tor para restabelecer a conexão com a outra pessoa.
Uma introdução aos perfis Cwtch.
Com Cwtch você pode criar um ou mais perfis . Cada perfil gera um par de chaves ed25519 aleatório compatível com a Rede Tor.
Este é o identificador que você pode fornecer às pessoas e que elas podem usar para entrar em contato com você via Cwtch.
Cwtch permite criar e gerenciar vários perfis separados. Cada perfil está associado a um par de chaves diferente que inicia um serviço cebola diferente.
Gerenciar Na inicialização, o Cwtch abrirá a tela Gerenciar Perfis. Nessa tela você pode:
- Crie um novo perfil.
- Desbloquear perfis.
- Criptografados existentes.
- Gerenciar perfis carregados.

Uma vez confirmado, o Cwtch tentará descriptografar o arquivo fornecido usando uma chave derivada da senha fornecida. Se for bem-sucedido, o perfil aparecerá na tela Gerenciamento de perfil e estará pronto para uso.
OBSERVAÇÃO Embora um perfil possa ser importado para vários dispositivos, atualmente apenas uma versão de um perfil pode ser usada em todos os dispositivos ao mesmo tempo. As tentativas de usar o mesmo perfil em vários dispositivos podem resultar em problemas de disponibilidade e falhas de mensagens.
Qual é a diferença entre uma conexão ponto a ponto e um grupo cwtch?
As conexões ponto a ponto Cwtch permitem que 2 pessoas troquem mensagens diretamente. As conexões ponto a ponto nos bastidores usam serviços cebola Tor v3 para fornecer uma conexão criptografada e resistente a metadados. Devido a esta conexão direta, ambas as partes precisam estar online ao mesmo tempo para trocar mensagens.
Os Grupos Cwtch permitem que várias partes participem de uma única conversa usando um servidor não confiável (que pode ser fornecido por terceiros ou auto-hospedado). Os operadores de servidores não conseguem saber quantas pessoas estão em um grupo ou o que está sendo discutido. Se vários grupos estiverem hospedados em um único servidor, o servidor não conseguirá saber quais mensagens pertencem a qual grupo sem a conivência de um membro do grupo. Ao contrário das conversas entre pares, as conversas em grupo podem ser conduzidas de forma assíncrona, para que todos num grupo não precisem estar online ao mesmo tempo.
Por que os grupos cwtch são experimentais? Mensagens em grupo resistentes a metadados ainda são um problema em aberto . Embora a versão que fornecemos no Cwtch Beta seja projetada para ser segura e com metadados privados, ela é bastante ineficiente e pode ser mal utilizada. Como tal, aconselhamos cautela ao usá-lo e apenas o fornecemos como um recurso opcional.
Como posso executar meu próprio servidor Cwtch? A implementação de referência para um servidor Cwtch é de código aberto . Qualquer pessoa pode executar um servidor Cwtch, e qualquer pessoa com uma cópia do pacote de chaves públicas do servidor pode hospedar grupos nesse servidor sem que o operador tenha acesso aos metadados relacionados ao grupo .
https://git.openprivacy.ca/cwtch.im/server
https://docs.openprivacy.ca/cwtch-security-handbook/server.html
Como posso desligar o Cwtch? O painel frontal do aplicativo possui um ícone do botão "Shutdown Cwtch" (com um 'X'). Pressionar este botão irá acionar uma caixa de diálogo e, na confirmação, o Cwtch será desligado e todos os perfis serão descarregados.

2025-05-13 06:32:15You don’t have to be a type designer to appreciate what goes into the design of a letterform. In fact, even if you’re just a humble graphic designer, you should have a basic knowledge of what constructs the type you employ.
Typography, for all its concepts, expectations, implications, connotations and artistry, is, ultimately, a system. Just like a body has bones and muscles, every letterform has parts that give it shape, rhythm, and character.
If you're a creative working with type, learning the names of these parts helps you communicate clearly, better analyze your work and others, and design with precision. Everything comes down to a foundational understanding of the anatomy of the letterform and its essential component. So let’s help you with that.
Pangram Pangram Foundry is where the art of typography meets unparalleled craftsmanship. Established in 2018 by designer Mat Desjardins, Pangram Pangram has swiftly risen to become a globally recognized independent type foundry, admired and trusted by industry peers and the design community alike.

2025-05-19 22:33:33タイトルは釣りです。そんなこと微塵も思っていません。 本稿はアウトボックスモデルの実装に関してうだうだ考えるコーナーです。 ダムスに関して何か言いたいわけではないので先にタイトル回収しておきます。
- NIP-65を守る気なんかさらさら無いのにNIP-65に書いてあるkind:10002のReadリレーの意味を知っていながら全然違う使い方をしているのは一部の和製クライアントの方だよね
- NIP-65を守る気が無いならkind:10002を使うべきではなく、独自仕様でリレーを保存するべきだよね
- アウトボックスモデルを採用しているクライアントからすれば仕様と異なる実装をしてしまっているクライアントが迷惑だと思われても仕方ないよね
- と考えればダムスの方が潔いよね
- とはいえkind:3のcontentは空にしろって言われてんだからやっぱダムスはゴミだわ
- やるとしたらRabbitみたいにローカルに保存するか、別デバイス間で同期したいならkind:30078を使うべきだよね
アウトボックスモデルはなぜ人気がないのか
言ってることはとてもいいと思うんですよ。 欠点があるとすれば、
- 末端のユーザーからすればreadリレーとwriteリレーと書かれると直感的にイメージされるものとかけ離れている
- 正しく設定してもらうには相当の説明が必要
- フォローTLを表示しようとすれば非常にたくさんのリレーと接続することになり現実的ではない
- なるほど完璧な作戦っスねーっ 不可能だという点に目をつぶればよぉ~
余談ですが昔irisでログインした時に localhost のリレーに繋ごうとしてiris壊れたって思ったけど今思えばアウトボックスモデルを忠実に実装してたんじゃないかな…。
現実的に実装する方法は無いのか
これでReadすべきリレーをシミュレーションできる。 https://nikolat.github.io/nostr-relay-trend/ フォローイーのWriteリレーを全部購読しようとすると100個近いリレー数になるので現実的ではありません。 しかしフォローイーのWriteリレーのうち1個だけでよい、とする条件を仮に追加すると一気にハードルが下がります。私の場合はReadリレー含めて7個のリレーに収まりました。 Nos Haikuはとりあえずこの方針でいくことにしました。
今後どうしていきたいのか
エンドユーザーとしての自分の志向としては、自分が指定したリレーだけを購読してほしい、勝手に余計なリレーを読みに行かないでほしい、という気持ちがあり、現状の和製クライアントの仕様を気に入っています。 仮にNos Haikuでアウトボックスモデルを採用しつつ自分の決めたリレーに接続するハイブリッド実装を考えるとすれば、
あなたの購読するリレーはこれですよー - Read(inbox) Relays (あなたへのメンションが届くリレー) - wss://relay1.example.com/ - wss://relay2.example.com/ - wss://relay3.example.com/ - Followee's Write Relays (フォローイーが書き込んでいるリレー) - wss://relay4.example.com/ - wss://relay5.example.com/ - wss://relay6.example.com/って出して、チェックボックス付けてON/OFFできるようにして最終的に購読するリレーをユーザーに決めてもらう感じかな……って漠然と考えています。よほど時間を持て余したときがあればやってみるかも。
あとリレーを数は仕方ないとしてリレーごとにフォローイーの投稿だけを取得するようにした方が理にかなってるよね。全部のリレーから全部のフォローイーの投稿を取得しようとしたら(実装はシンプルで楽だけど)通信量が大変だよね。 rx-nostr の Forward Strategy ってリレーごとにREQかえて一度に購読できるっけ?
常にひとつ以下の REQ サブスクリプションを保持します。
って書いてあるから無理なのかな? あとReadリレーは純粋に自分へのメンション(pタグ付き)イベントのみを購読するようにした方がいい気がする。スパム対策としてかなり有効だと思うので。スパムはNIP-65に準拠したりはしていないでしょうし。 まぁ、NIP-65に準拠していないクライアントからのメンションは届かなくなってしまうわけですが。

2025-05-17 08:26:13背景:WhatsApp的号码验证与运营商合作关系
作为一款基于手机号码注册的即时通信应用,WhatsApp的账号验证严重依赖全球电信运营商提供的短信或电话服务。这意味着,当用户注册或在新设备登录WhatsApp时,WhatsApp通常会向用户的手机号码发送SMS短信验证码或发起语音电话验证。这一流程利用了传统电信网络的基础设施,例如通过SS7(信令系统7)协议在全球范围内路由短信和电话securityaffairs.com。换句话说,WhatsApp把初始账户验证的安全性建立在电信运营商网络之上。然而,这种依赖关系也带来了隐患:攻击者可以利用电信网络的漏洞来拦截验证码。例如,研究人员早在2016年就演示过利用SS7协议漏洞拦截WhatsApp和Telegram的验证短信,从而劫持用户账户的攻击方法securityaffairs.com。由于SS7协议在全球范围内连接各国运营商,一个运营商的安全缺陷或恶意行为都可能被不法分子利用来获取他网用户的短信验证码securityaffairs.com。正因如此,有安全专家指出,仅依赖短信验证不足以保障账户安全,WhatsApp等服务提供商需要考虑引入额外机制来核实用户身份securityaffairs.com。
除了技术漏洞,基于电信运营商的验证还受到各地政策和网络环境影响。WhatsApp必须与全球各地运营商“合作”,才能将验证码送达到用户手机。然而这种“合作”在某些国家可能并不顺畅,典型例子就是中国。在中国大陆,国际短信和跨境电话常受到严格管控,WhatsApp在发送验证码时可能遭遇拦截或延迟sohu.com。因此,理解WhatsApp在中国的特殊联网和验证要求,需要将其全球验证机制与中国的电信政策和网络审查环境联系起来。下文将深入探讨为什么在中国使用WhatsApp进行号码验证时,必须开启蜂窝移动数据,并分析其中的技术逻辑和政策因素。
中国环境下的特殊问题:为何必须开启蜂窝数据?
中国的网络审查与封锁: WhatsApp自2017年起就在中国大陆遭遇严格封锁。起初,WhatsApp在华的服务受到**“GFW”(防火长城)**的部分干扰——例如曾一度只能发送文本消息,语音、视频和图片消息被封锁theguardian.com。到2017年下半年,封锁升级,很多用户报告在中国完全无法使用WhatsApp收发任何消息theguardian.com。中国官方将WhatsApp与Facebook、Telegram等西方通信平台一同屏蔽,视作对国家网络主权的挑战theguardian.com。鉴于此,在中国境内直接访问WhatsApp的服务器(无论通过Wi-Fi还是本地互联网)都会被防火长城所阻断。即使用户收到了短信验证码,WhatsApp客户端也无法在没有特殊连接手段的情况下与服务器完成验证通信。因此,单纯依赖Wi-Fi等本地网络环境往往无法完成WhatsApp的注册或登陆。很多用户经验表明,在中国使用WhatsApp时需要借助VPN等工具绕过审查,同时尽可能避免走被审查的网络路径sohu.com。
强制Wi-Fi热点与连接策略: 除了国家级的封锁,用户所连接的局域网络也可能影响WhatsApp验证。许多公共Wi-Fi(如机场、商场)采取强制门户认证(captive portal),用户需登录认证后才能上网。对此,WhatsApp在客户端内置了检测机制,当发现设备连入这类强制Wi-Fi热点而无法访问互联网时,会提示用户忽略该Wi-Fi并改用移动数据faq.whatsapp.com。WhatsApp要求对此授予读取Wi-Fi状态的权限,以便在检测到被拦截时自动切换网络faq.whatsapp.com。对于中国用户来说,即便所连Wi-Fi本身联网正常,由于GFW的存在WhatsApp依然可能视之为“不通畅”的网络环境。这也是WhatsApp官方指南中强调:如果Wi-Fi网络无法连接WhatsApp服务,应直接切换到手机的移动数据网络faq.whatsapp.com。在中国,由于本地宽带网络对WhatsApp的封锁,蜂窝数据反而成为相对可靠的通道——尤其在搭配VPN时,可以避开本地ISP的审查策略,实现与WhatsApp服务器的通信sohu.com。
国际短信的运营商限制: 使用移动数据还有助于解决短信验证码接收难题。中国的手机运营商出于防垃圾短信和安全考虑,默认对国际短信和境外来电进行一定限制。许多中国用户发现,注册WhatsApp时迟迟收不到验证码短信,原因可能在于运营商将来自国外服务号码的短信拦截或过滤sohu.com。例如,中国移动默认关闭国际短信接收,需要用户主动发送短信指令申请开通sohu.com。具体而言,中国移动用户需发送文本“11111”到10086(或10085)来开通国际短信收发权限;中国联通和电信用户也被建议联系运营商确认未屏蔽国际短信sohu.com。若未进行这些设置,WhatsApp发送的验证码短信可能根本无法抵达用户手机。在这种情况下,WhatsApp提供的备用方案是语音电话验证,即通过国际电话拨打用户号码并播报验证码。然而境外来电在中国也可能遭到运营商的安全拦截,特别是当号码被认为可疑时zhuanlan.zhihu.com。因此,中国用户经常被建议开启手机的蜂窝数据和漫游功能,以提高验证码接收的成功率sohu.com。一方面,开启数据漫游意味着用户准备接受来自境外的通信(通常也包含短信/电话);另一方面,在数据联网的状态下,WhatsApp可以尝试通过网络直接完成验证通信,从而减少对SMS的依赖。
移动数据的网络路径优势: 在实际案例中,一些中国WhatsApp用户报告仅在开启蜂窝数据的情况下才能完成验证。这可能归因于蜂窝网络和宽带网络在国际出口上的差异。中国移动、联通等运营商的移动数据可能走与宽带不同的网关路由,有时对跨境小流量的拦截相对宽松。此外,WhatsApp在移动数据环境中可以利用一些底层网络特性。例如,WhatsApp可能通过移动网络发起某些专用请求或利用运营商提供的号码归属地信息进行辅助验证(虽然具体实现未公开,但这是业界讨论的可能性)。总之,在中国特殊的网络环境下,开启蜂窝数据是确保WhatsApp验证流程顺利的重要一步。这一步不仅是为了基本的互联网连接,也是为了绕开种种对国际短信和应用数据的拦截限制,从而与WhatsApp的全球基础设施建立必要的通讯。
PDP Context与IMSI:移动网络验证的技术细节
要理解为什么移动数据对WhatsApp验证如此关键,有必要了解移动通信网络中的一些技术细节,包括PDP Context和IMSI的概念。
PDP Context(分组数据协议上下文): 当手机通过蜂窝网络使用数据(如4G/5G上网)时,必须先在运营商核心网中建立一个PDP上下文。这实际上就是申请开启一个数据会话,运营商将为设备分配一个IP地址,并允许其通过移动核心网访问互联网datascientest.com。PDP上下文包含了一系列参数(例如APN接入点名称、QoS等级等),描述该数据会话的属性datascientest.comdatascientest.com。简单来说,激活蜂窝数据就意味着创建了PDP上下文,设备获得了移动网络网关分配的IP地址,可以收发数据包。对于WhatsApp验证而言,只有在建立数据连接后,手机才能直接与WhatsApp的服务器交换数据,例如提交验证码、完成加密密钥协商等。如果仅有Wi-Fi而蜂窝数据关闭,且Wi-Fi环境无法连通WhatsApp服务器,那么验证过程将陷入停滞。因此,在中国场景下,开启蜂窝数据(即建立PDP数据通路)是WhatsApp客户端尝试绕过Wi-Fi限制、直接通过移动网络进行验证通信的前提faq.whatsapp.comsohu.com。值得一提的是,PDP Context的建立也表明手机在运营商网络上处于活跃状态,这对于某些验证机制(比如后述的闪信/闪呼)来说至关重要。
IMSI与MSISDN: IMSI(国际移动用户标识)和MSISDN(移动用户号码,即手机号码)是运营商网络中两个密切相关但不同的标识。IMSI是存储在SIM卡上的一串唯一数字,用于在移动网络中标识用户身份netmanias.com。当手机接入网络时,它向运营商提供IMSI以进行鉴权,运营商据此知道“是哪张SIM”的请求netmanias.com。而MSISDN则是我们平常说的手机号,用于在语音通话和短信路由中定位用户,也存储在运营商的HLR/HSS数据库中netmanias.com。运营商通过IMSI<->MSISDN的对应关系,将来自全球的短信/电话正确路由到用户手机上。WhatsApp的验证短信或电话本质上就是通过目标号码(MSISDN)寻找所属运营商网络,由该网络根据IMSI定位用户终端。一般情况下,WhatsApp应用并不直接接触IMSI这种信息,因为IMSI属于运营商网络的内部标识。然而,IMSI的存在仍然对安全产生影响。例如,**SIM卡交换(SIM Swap)**欺诈发生时,攻击者获得了受害者号码的新SIM卡,新SIM卡会有不同的IMSI,但MSISDN保持原号码不变。运营商会将原号码映射到新的IMSI,这样验证码短信就发送到了攻击者手中的SIM上。对WhatsApp而言,除非有机制检测IMSI变动,否则无法察觉用户号码背后的SIM已被盗换。部分应用在检测到SIM变化时会提示用户重新验证,这需要读取设备的IMSI信息进行比对。然而,在现代智能手机中,获取IMSI通常需要特殊权限,WhatsApp并未明确说明它有此类检测。因此,从WhatsApp角度,IMSI更多是网络侧的概念,但它提醒我们:电信级身份验证依赖于SIM的有效性。只有当正确的IMSI在网络注册、并建立了PDP数据上下文时,WhatsApp的后台服务才能确认该SIM对应的号码目前“在线”,进而可靠地发送验证信号(短信或电话)到该设备。
移动网络的信号辅助验证: 有观点认为,一些OTT应用可能利用移动网络提供的附加服务来辅助号码验证。例如,某些运营商提供号码快速验证API,当应用检测到设备在移动数据网络中时,可以向特定地址发起请求,由运营商返回当前设备的号码信息(通常通过已经建立的PDP通道)。Google等公司在部分国家与运营商合作过类似服务,实现用户免输入验证码自动完成验证。但就WhatsApp而言,没有公开证据表明其使用了运营商提供的自动号码识别API。即便如此,WhatsApp鼓励用户保持移动网络在线的做法,隐含的意义之一可能是:当手机处于蜂窝网络且数据畅通时,验证码通过率和验证成功率都会显著提升。这既包括了物理层面短信、电话能否送达,也涵盖了数据层面应用和服务器能否互通。
Flash Call机制:WhatsApp验证的新方案
针对传统SMS验证码容易被拦截、延迟以及用户体验不佳的问题,WhatsApp近年来引入了一种Flash Call(闪呼)验证机制fossbytes.com。所谓闪呼,即应用在用户验证阶段向用户的手机号发起一个非常短暂的来电:用户无需真正接听,WhatsApp会自动结束这通电话,并根据通话记录来确认是否拨通fossbytes.com。
原理与流程: 当用户选择使用闪呼验证(目前主要在Android设备上可用),WhatsApp会请求权限访问用户的通话记录fossbytes.com。随后应用拨打用户的号码,一般是一个预先设定的特定号码或号码段。由于WhatsApp后台知道它拨出的号码及通话ID,只要该未接来电出现在用户手机的通话日志中,应用即可读取并匹配最后一通来电的号码是否符合验证要求,从而确认用户持有这个号码fossbytes.com。整个过程用户无需手动输入验证码,验证通话在数秒内完成。相比6位数字短信验证码需要用户在短信和应用间切换输入,闪呼方式更加快捷无缝fossbytes.com。
优缺点分析: 闪呼验证的优势在于速度快且避免了SMS可能的延迟或拦截。一些分析指出闪呼将成为取代SMS OTP(一次性密码)的新趋势,Juniper Research预测2022年用于验证的闪呼次数将从2021年的六千万猛增到五十亿次subex.comglobaltelcoconsult.com。对于WhatsApp这样全球用户庞大的应用,闪呼可以节约大量SMS网关费用,并绕开部分运营商对国际SMS的限制。然而,闪呼也有局限:fossbytes.com首先,iOS设备由于系统安全限制,应用无法访问通话记录,因此iPhone上无法使用闪呼验证fossbytes.com。这意味着苹果用户仍需使用传统短信验证码。其次,为实现自动匹配来电号码,用户必须授予读取通话记录的权限,这在隐私上引发一些担忧fossbytes.comfossbytes.com。WhatsApp声称不会将通话记录用于验证以外的用途,号码匹配也在本地完成fossbytes.com,但考虑到母公司Meta的隐私争议,部分用户依然顾虑。第三,闪呼验证依赖语音通话路线,同样受制于电信网络质量。如果用户所处网络无法接通国际来电(比如被运营商拦截境外短振铃电话),闪呼也无法成功。此外,从运营商角度看,闪呼绕过了A2P短信计费,可能侵蚀短信营收,一些运营商开始研究识别闪呼流量的策略wholesale.orange.com。总体而言,闪呼机制体现了WhatsApp希望减轻对短信依赖的努力,它在许多国家提升了验证体验,但在中国等特殊环境,其效果仍取决于本地语音网络的开放程度。值得注意的是,中国运营商对于境外电话,尤其是这种**“零响铃”未接来电**也有防范措施,中国电信和联通用户就被建议如需接收海外来电验证,应联系客服确保未拦截海外来电hqsmartcloud.com。因此,即便WhatsApp支持闪呼,中国用户若未开启移动语音漫游或运营商许可,仍然难以通过此途径完成验证。
与SIM Swap安全性的关系: 从安全角度看,闪呼并未实质提升抵御SIM交换攻击的能力。如果攻击者成功将受害者的号码转移至自己的SIM卡上(获取新IMSI),那么无论验证码以短信还是闪呼方式发送,都会到达攻击者设备。闪呼机制能防御的是部分恶意拦截短信的行为(如恶意网关或木马读取短信),但对社工换卡没有太大帮助。WhatsApp早已提供两步验证(即设置6位PIN码)供用户自行启用,以防号码被他人重新注册时需要额外密码。然而大量用户未开启该功能。因此,闪呼更多是从用户体验和成本出发的改良,而非针对高级别攻击的防护机制。正如前文所述,真正要防御SIM Swap和SS7漏洞等系统性风险,依赖运营商的号码验证本身就是薄弱环节,需要引入更高级的身份认证手段。
SIM卡交换攻击的风险与运营商信任问题
WhatsApp和Telegram一类基于手机号认证的应用普遍面临一个安全挑战:手机号码本身并非绝对安全的身份凭证。攻击者可以通过一系列手段取得用户的号码控制权,其中SIM交换(SIM Swap)是近年高发的欺诈手法。SIM Swap通常由不法分子冒充用户,诱骗或贿赂运营商客服将目标号码的服务转移到攻击者的新SIM卡上keepnetlabs.com。一旦成功,所有发往该号码的短信和电话都转由攻击者接收,原机主的SIM卡失效。对于依赖短信/电话验证的应用来说,这意味着攻击者可以轻易获取验证码,从而重置账户并登录。近年来全球SIM Swap案件呈上升趋势,许多在线服务的账号被此攻破rte.ie。
WhatsApp并非未知晓此风险。事实上,WhatsApp在其帮助中心和安全博客中多次提醒用户开启两步验证PIN,并强调绝不向他人透露短信验证码。然而,从系统设计上讲,WhatsApp仍将信任根基放在运营商发送到用户手机的那串数字验证码上。一旦运营商端的安全被绕过(无论是内部员工作恶、社工欺诈,还是SS7网络被黑客利用securityaffairs.com),WhatsApp本身无法辨别验证码接收者是否是真正的用户。正如安全研究所Positive Technologies指出的那样,目前主要的即时通讯服务(包括WhatsApp和Telegram)依赖SMS作为主要验证机制,这使得黑客能够通过攻击电信信令网络来接管用户账户securityaffairs.com。换言之,WhatsApp被迫信任每一个参与短信/电话路由的运营商,但这个信任链条上任何薄弱环节都可能遭到利用securityaffairs.com。例如,在SIM Swap攻击中,运营商本身成为被欺骗的对象;而在SS7定位拦截攻击中,全球互联的电信网成为攻击面。在中国的场景下,虽然主要威胁来自审查而非黑客,但本质上仍是WhatsApp无法完全掌控电信网络这一事实所导致的问题。
应对这些风险,WhatsApp和Telegram等采用了一些弥补措施。除了提供用户自行设定的二次密码,两者也开始探索设备多因子的概念(如后文Telegram部分所述,利用已有登录设备确认新登录)。然而,对绝大多数首次注册或更换设备的用户来说,传统的短信/电话验证仍是唯一途径。这就是为什么在高安全需求的行业中,SMS OTP正逐渐被视为不充分securityaffairs.com。监管机构和安全专家建议对涉敏感操作采用更强验证,如专用身份应用、硬件令牌或生物识别等。WhatsApp作为大众通信工具,目前平衡了易用性与安全性,但其依赖电信运营商的验证模式在像中国这样特殊的环境下,既遇到政策阻碍,也隐藏安全短板。这一点对于决策制定者评估国外通信应用在华风险时,是一个重要考量:任何全球运营商合作机制,在中国境内都可能因为**“最后一公里”由中国运营商执行**而受到影响。无论是被拦截信息还是可能的监控窃听,这些风险都源自于底层通信网的控制权不在应用服务商手中。
Telegram登录机制的比较
作为对比,Telegram的账号登录机制与WhatsApp类似,也以手机号码为主要身份标识,但在具体实现上有一些不同之处。
多设备登录与云端代码: Telegram从设计上支持多设备同时在线(手机、平板、PC等),并将聊天内容储存在云端。这带来的一个直接好处是:当用户在新设备上登录时,Telegram会优先通过已登录的其他设备发送登录验证码。例如,用户尝试在电脑上登录Telegram,Telegram会在用户手机上的Telegram应用里推送一条消息包含登录码,而不是立即发短信accountboy.comaccountboy.com。用户只需在新设备输入从老设备上收到的代码即可完成登录。这种机制确保了只要用户至少有一个设备在线,就几乎不需要依赖运营商短信。当然,如果用户当前只有一部新设备(例如换了手机且旧设备不上线),Telegram才会退而求其次,通过SMS发送验证码到手机号。同时,Telegram也允许用户选择语音电话获取验证码,类似于WhatsApp的语音验证。当用户完全无法收到SMS时(比如在中国这种场景),语音呼叫常常比短信更可靠seatuo.com。
两步验证密码: 与WhatsApp一样,Telegram提供可选的两步验证密码。当启用此功能后,即使拿到短信验证码,仍需输入用户设置的密码才能登录账户quora.com。这对抗SIM Swap等攻击提供了另一层防线。不过需要指出,如果用户忘记了设置的Telegram密码且没有设置信任邮箱,可能会永久失去账号访问,因此开启该功能在中国用户中接受度一般。
登录体验与安全性的取舍: Telegram的登录流程在用户体验上更加灵活。多设备下无需每次都收验证码,提高了便利性。但从安全角度看,这种“信任已有设备”的做法也有隐患:如果用户的某个设备落入他人之手并未及时登出,那么该人有可能利用该设备获取新的登录验证码。因此Telegram会在应用中提供管理活动会话的功能,用户可随时查看和撤销其它设备的登录状态telegram.org。总体而言,Telegram和WhatsApp在初始注册环节同样依赖短信/电话,在这一点上,中国的网络环境对两者影响相似:Telegram在中国同样被全面封锁,需要VPN才能使用,其短信验证码发送也会受到运营商限制。另外,Telegram曾在2015年因恐怖分子利用该平台传递信息而被中国当局重点关注并屏蔽,因此其国内可达性甚至比WhatsApp更低。许多中国用户实际使用Telegram时,通常绑定国外号码或通过海外SIM卡来收取验证码,以绕开国内运营商的限制。
差异总结: 简而言之,Telegram在登录验证机制上的主要优势在于已有会话协助和云端同步。这使得老用户换设备时不依赖国内短信通道即可登录(前提是原设备已登录并可访问)。WhatsApp直到最近才推出多设备功能,但其多设备模式采用的是端到端加密设备链路,需要主手机扫码授权,而非像Telegram那样用账号密码登录其它设备。因此WhatsApp仍然强绑定SIM卡设备,首次注册和更换手机号时逃不开运营商环节。安全方面,两者的SMS验证所面临的系统性风险(如SS7攻击、SIM Swap)并无本质区别,都必须仰仗运营商加强对核心网络的保护,以及用户自身启用附加验证措施securityaffairs.comkeepnetlabs.com。
结论
对于希望在中国使用WhatsApp的用户来说,“开启蜂窝数据”这一要求背后体现的是技术与政策交织的复杂现实。一方面,蜂窝数据承载着WhatsApp与其全球服务器通信的关键信道,在中国的受限网络中提供了相对可靠的出路faq.whatsapp.comsohu.com。另一方面,WhatsApp的号码验证机制深深植根于传统电信体系,必须经由全球运营商的“协作”才能完成用户身份确认securityaffairs.com。而在中国,这种协作受到防火长城和运营商政策的双重阻碍:国际短信被拦截、国际数据被阻断。为克服这些障碍,WhatsApp既采取了工程上的应对(如检测强制Wi-Fi并提示使用移动网络faq.whatsapp.com),也引入了诸如闪呼验证等新方案以减少对短信的依赖fossbytes.com。但从根本上说,只要注册流程离不开手机号码,这种与电信运营商的捆绑关系就无法割舍。由此带来的安全问题(如SIM Swap和信令网络漏洞)在全球范围内敲响警钟securityaffairs.comkeepnetlabs.com。
对于从事安全研究和政策评估的人士,这篇分析揭示了WhatsApp在中国遇到的典型困境:技术系统的全球化与监管环境的本地化冲突。WhatsApp全球统一的验证框架在中国水土不服,不得不通过额外的设置和手段来“曲线救国”。这既包括让用户切换网络、配置VPN等绕过审查,也包括思考未来是否有必要采用更安全独立的验证方式。相比之下,Telegram的机制给出了一种启示:灵活运用多设备和云服务,至少在一定程度上降低对单一短信渠道的依赖。然而,Telegram自身在中国的处境表明,再优雅的技术方案也难以直接对抗高强度的网络封锁。最终,无论是WhatsApp还是Telegram,要想在受限环境下可靠运作,都需要技术与政策的双管齐下:一方面提高验证与登录的安全性和多样性,另一方面寻求运营商和监管层面的理解与配合。
综上所述,WhatsApp要求中国用户开启蜂窝数据并非偶然的臆想,而是其全球运营商合作验证机制在中国受阻后的务实选择。这一要求折射出移动通信应用在跨境运营中面临的挑战,也提醒我们在设计安全策略时必须考虑底层依赖的信任假设。对于个人用户,最实际的建议是在使用此类应用时提前了解并遵循这些特殊设置(如开通国际短信、启用数据漫游),并善用应用自身的安全功能(如两步验证)来保护账户免遭社工和网络攻击keepnetlabs.com。对于监管和运营商,则有必要权衡安全审查与用户便利之间的平衡,在可控范围内为可信的全球服务留出技术通道。在全球通信愈加融合的时代,WhatsApp的中国验证问题或许只是一个缩影,背后涉及的既有网络安全考量,也有数字主权与国际合作的议题,值得持续深入研究和关注。

2025-05-13 06:21:36Steve Jobs sent me an email saying “Great idea, thank you."
Wait, what? What was the great idea?
new guy at NeXT In October of 1991, I was a new Systems Engineer at NeXT. NeXT, of course, was the company Steve Jobs had founded after leaving Apple in 1985, and which eventually merged back into Apple in 1996. I was one of three employees in Canada, and I think NeXT had about 400 people total.
NeXTMail Mail on the NeXT Computer was pretty amazing in 1991. Multimedia! Fonts! Attachments! Sounds! It’s hard to overstate how cool that was compared to the command line email everybody was used to. Every NeXT user got this email from Steve when they started up their computer.
That message included an attachment of what NeXT called Lip Service, the crazy idea that you could embed an audio file inside an email message. Crazy.
i have an idea
NeXT automatically set everybody up with a first-initial last-name address in the usual way, so I was shayman@next.com, and the big guy was sjobs@next.com.
A few colleagues had somehow acquired cooler email aliases - single letter things, or their first name, or a nickname or an easier to spell version, or whatever. Turns out NeXT had set up some sort of form where you could request an email alias that would redirect to whatever your real email address was.
I also noticed that even though there were seven or eight people at NeXT named Steve, nobody was using the email alias steve@next.com.
So late one Friday night, two weeks into the job, I figured, naively, what the heck, nobody else seems to want it, so I filled in the form asking for steve@next.com to be forwarded to me, shayman@next.com.
In the back of my mind was a vague idea that maybe somebody would have to approve this. But no, it all got set up automatically, and …

2025-02-01 11:16:04Federal employees must remove pronouns from email signatures by the end of the day. This directive comes from internal memos tied to two executive orders signed by Donald Trump. The orders target diversity and equity programs within the government.
CDC, Department of Transportation, and Department of Energy employees were affected. Staff were instructed to make changes in line with revised policy prohibiting certain language.
One CDC employee shared frustration, stating, “In my decade-plus years at CDC, I've never been told what I can and can't put in my email signature.” The directive is part of a broader effort to eliminate DEI initiatives from federal discourse.

BitMine Launches Bitcoin Treasury Advisory Practice, Secures $4M Deal with First ClientToday, BitMine Immersion Technologies, Inc. (OTCQX: BMNRD) announced the launch of its Bitcoin Treasury Advisory Practice and a $4 million deal with a U.S. exchange-listed company. The deal saw Bitmine surpass its last year’s total revenue in that single transaction alone, according to the announcement.
BitMine ( OTCQX: $BMNRD $BMNR) launches Bitcoin Treasury Advisory Practice and secures $4M deal with first client.
This single transaction exceeds our 2024 revenue and sets the stage for major growth.

— Bitmine Immersion Technologies, Inc. (@BitMNR) May 19, 2025
BitMine will provide “Mining as a Service” (MaaS) by leasing 3,000 Bitcoin ASIC miners to the client through December 30, 2025, in a $3.2 million lease deal, with $1.6 million paid upfront. Additionally, the client has signed an $800,000 consulting agreement for one year focusing on Bitcoin Mining-as-a-Service and Bitcoin Treasury Strategy.
“Currently, there are almost 100 public companies that have adopted Bitcoin as a treasury holding. We expect this number to grow in the future. As more companies adopt Bitcoin treasury strategies, the need for infrastructure, revenue generation, and expert guidance grows along with it,” said Jonathan Bates, CEO of BitMine. “This single transaction is greater than our entire 2024 fiscal year revenue, and we feel there is an opportunity to acquire more clients in the near future as interest in Bitcoin ownership grows.”
BitMine’s first quarter 2025 results showed strong revenue growth, with GAAP revenue rising approximately 135% to $1.2 million, up from $511,000 in Q1 2024, supported by an expanded mining capacity of 4,640 miners as of November 30, 2024, compared to 1,606 the previous year. Despite this growth, the company reported a net loss of $3.9 million in Q1 2025, primarily due to a one-time, non-cash accounting adjustment related to preferred stock; excluding this charge, the adjusted loss was approximately $975,000, consistent with the prior year’s results.
$BMNR reports a 135% revenue increase YOY for Q1 2025 and tripled self-mining capacity with 3,000 new miners! CEO Jonathan Bates credits a team-driven approach and creative financing for this growth.

Wer einhundert Prozent seines Einkommens abgeben muss, ist sicher ein Sklave, oder? Aber ab wieviel Prozent Pflichtabgabe ist er denn kein Sklave mehr? Ab wann ist er frei und selbst-bestimmt?
Wer definieren möchte, was ein Sklave ist, sollte nicht bei Pflichtabgaben verweilen, denn die Fremdbestimmtheit geht viel weiter. Vielfach hat der gewöhnliche Mensch wenig Einfluss darauf, wie er und seine Familie misshandelt wird. Es wird verfügt, welche Bildung, welche Nahrung, welche Medikamente, welche Impfungen und welche Kriege er zu erdulden hat. Hierbei erkennt der gewöhnliche Mensch aber nur, wer ihm direkt etwas an-tut. So wie der Gefolterte bestenfalls seinen Folterer wahrnimmt, aber nicht den, in dessen Auftrag dieser handelt, so haben die vorbezeichnet Geschädigten mit Lehrern, „Experten“, Ärzten und Politikern zu tun. Ebenfalls ohne zu wissen, in wessen Auftrag diese Leute handeln. „Führungssysteme“ sind so konzipiert, dass für viele Menschen bereits kleinste wahrgenommene Vorteile genügen, um einem anderen Menschen Schlimmes anzutun.
Aber warum genau wird Menschen Schlimmes angetan? Die Gründe dafür sind stets dieselben. Der Täter hat ein Motiv und Motivlagen können vielfältig sein.
Wer also ein Motiv hat, ein Geschehen zu beeinflussen, motiviert andere zur Unterstützung. Wem es gelingt, bei anderen den Wunsch zu erwecken, das zu tun, was er möchte, ist wirklich mächtig. Und es sind die Mächtigen im Hintergrund, welche die Darsteller auf den Bühnen dieser Welt dazu nutzen, die Interessen der wirklich Mächtigen durchzusetzen. Insbesondere die letzten fünf Jahre haben eindrucksvoll gezeigt, wie willfährig Politiker, Ärzte, Experten und viele weitere ihre jeweiligen Aufträge gegen die Bevölkerung durchsetz(t)en.
Und so geschieht es auch beim aktuellen Krieg, der stellvertretend auf dem europäischen Kontinent ausgetragen wird. Parolen wie „nie wieder Krieg“ gehören der Vergangenheit an. Stattdessen ist nunmehr wieder der Krieg und nur der Krieg geeignet, um „Aggressionen des Gegners abzuwehren“ und um „uns zu verteidigen“.
Das hat mindestens drei gute Gründe:
- Mit einem Krieg können Sie einem anderen etwas wegnehmen, was er freiwillig nicht herausrückt. Auf diese Weise kommen Sie an dessen Land, seine Rohstoffe und sein Vermögen. Sie können ihn beherrschen und Ihren eigenen Einfluss ausbauen. Je mehr Ihnen gehört, um so besser ist das für Sie. Sie müssen sich weniger abstimmen und Widersacher werden einfach ausgeschaltet.
- Wenn etwas über einen langen Zeitraum aufgebaut wurde, ist es irgendwann auch einmal fertig. Um aber viel Geld verdienen und etwas nach eigenen Vorstellungen gestalten zu können, muss immer wieder etwas Neues erschaffen werden, und da stört das Alte nur. Demzufolge ist ein Krieg ein geeignetes Mittel, etwas zu zerstören. Und das Schöne ist, dass man von Beginn an viel Geld verdient. Denn man muss dem indoktrinierten Volk nur vormachen, dass der Krieg „unbedingt erforderlich“ sei, um das Volk dann selbst bereitwillig für diesen Krieg bezahlen und auch sonst engagiert mitwirken zu lassen. Dann kann in Rüstung und „Kriegstauglichkeit“ investiert werden. Deutschland soll dem Vernehmen nach bereits in einigen Jahren „kriegstauglich“ sein. Der Gegner wartet sicher gerne mit seinen Angriffen, bis es so weit ist.
- Und nicht zu vergessen ist, dass man die vielen gewöhnlichen Menschen loswird. Schon immer wurden Populationen „reguliert“. Das macht bei Tieren ebenfalls so, indem man sie je nach „Erfordernis“ tötet. Und bei kollabierenden Systemen zu Zeiten von Automatisierung und KI unter Berücksichtigung der Klimarettung wissen doch mittlerweile alle, dass es viel zu viele Menschen auf dem Planeten gibt. Wenn jemand durch medizinische Misshandlungen oder auch durch einen Krieg direkt stirbt, zahlt dies auf die Lösung des Problems ein. Aber auch ein „Sterben auf Raten“ ist von großem Vorteil, denn durch die „fachmännische Behandlung von Verletzten“ bis zu deren jeweiligen Tode lässt sich am Leid viel verdienen.
Sie erkennen, dass es sehr vorteilhaft ist, Kriege zu führen, oder? Und diese exemplarisch genannten drei Gründe könnten noch beliebig erweitert werden.

Mehr Infos hier oder am Ende des Textes.
Das Einzige, was gegen Kriegsereignisse sprechen könnte, wäre, dass man selbst niemandem etwas wegnehmen möchte, was ihm gehört, und dass man seinen Mitmenschen nicht schaden, geschweige denn diese verletzen oder gar töten möchte.
In diesem Zusammenhang könnte man auch erkennen, dass die, die nach Krieg rufen, selbst nicht kämpfen. Auch deren Kinder nicht. Man könnte erkennen, dass man selbst nur benutzt wird, um die Interessen anderer durchzusetzen. Wie beim Brettspiel Schach hat jede Figur eine Funktion und keinem Spieler ist das Fortbestehen eines Bauern wichtig, wenn seine Entnahme dem Spielgewinn dient. Wer Krieg spielt, denkt sicher ähnlich.
Meine beiden Großväter waren Soldaten im zweiten Weltkrieg und erlebten die Grausamkeiten des Krieges und der Gefangenschaft so intensiv, dass sie mit uns Enkeln zu keiner Zeit hierüber sprechen konnten, da sie wohl wussten, dass uns allein ihre Erzählungen zutiefst traumatisiert hätten. Die Opas waren analog dem, was wir ihnen an Information abringen konnten, angeblich nur Sanitäter. Sanitäter, wie auch die meisten Großväter aus der Nachbarschaft. Wer aber jemals beobachten konnte, wie unbeholfen mein Opa ein Pflaster aufgebracht hat, der konnte sich denken, dass seine vermeintliche Tätigkeit als Sanitäter eine Notlüge war, um uns die Wahrheit nicht vermitteln zu müssen.
Mein Opa war mein bester Freund und mir treibt es unverändert die Tränen in die Augen, sein erlebtes Leid nachzuempfinden. Und trotz aller seelischen und körperlichen Verletzungen hat er nach seiner Rückkehr aus der Kriegshölle mit großem Erfolg daran gearbeitet, für seine Familie zu sorgen.
Manchmal ist es m. E. besser, die Dinge vom vorhersehbaren Ende aus zu betrachten, um zu entscheiden, welche Herausforderungen man annimmt und welche man besser ablehnt. Es brauchte fast 80 Jahre, um die Deutschen erneut dafür zu begeistern, Ihre Leben „für die gute Sache“ zu opfern. Was heutzutage aber anders ist als früher: Einerseits sind die Politiker dieser Tage sehr durchschaubar geworden. Aber in einem ähnlichen Verhältnis, wie die schauspielerischen Leistungen der Politiker abgenommen haben, hat die Volksverblödung zugenommen.
Denken Sie nicht nach. Denken Sie stattdessen vor. Und denken Sie selbst. Für sich, Ihre Lieben und alle anderen Menschen. Andernfalls wird die Geschichte, so wie sie von meinen Opas (und Omas) erlebt wurde, mit neuen Technologien und „zeitgemäßen Methoden“ wiederholt. Dies führt zweifelsfrei zu Not und Tod.

@ 2b998b04:86727e47
2025-05-19 21:18:46After the pruning came clarity.\ And after the clarity came a quiet but relentless question:\ What now?
If I wasn’t going back to Web3, if I wasn’t going to pretend anymore — not in faith, not in finance — then I needed to start building again. But this time, with different materials. Different rhythms. A different spirit.
Starting Over on Solid Ground
I’d spent years exploring tokens, networks, and well-intentioned communities. But most of it, I see now, was sand. It moved with the tides. The incentives shifted. The values bent. And when the storms came — personal, financial, spiritual — much of what I’d been part of collapsed or exposed its shallowness.
So I returned to the beginning: What can’t be faked?
That’s where Bitcoin came in — not just as an asset, but as a foundation.\ It taught me cost. Time. Truth. It doesn’t market itself. It just is.\ A system that punishes shortcuts, rewards discipline, and invites peace.
And the more I leaned in, the more I realized:\ This isn’t just money. This is philosophy. This is soil.
Pruned to Plant Again
I used to be a buy-and-hold investor. I still carry those instincts. But in 2020–21, I discovered trading — and with it, a new kind of discipline. Not gambling. Not speculation. Stewardship under pressure. Real-time decision-making with skin in the game.
My grandfather, who passed in the late '90s, probably would’ve looked a little dimly on trading. He lived off his dividends. Stocks he held for decades. He wasn’t chasing. He was rooting. But he would’ve respected the discipline — the clarity — when done right.
He also saw things I didn’t. He once told me I wasn’t raised properly. It hurt at the time, but now I understand. He saw the drift — not just in me, but in the culture. He understood that frugality means nothing if it’s not paired with truth.
I think he would’ve respected what I’m doing now — even if he wouldn't have fully understand it.
What I’m Building Now
-
StartNation – A Bitcoin-aligned equity accelerator. Proof-based. No tokens. No hype.
-
Golden Gate Group Investments – Real estate with a vision to integrate BTC in payments and ownership. Still early. Still real.
-
Blue Planet Ventures – Equities trading with daily proof-of-work and sats-based performance tracking.
-
A garden – Yes, literal food. Soil and seed. Hypdropnics. Bitcoin taught me patience; gardening reinforces it.
I’m not building a brand. I’m building a life. And I’m doing it in public — not to be seen, but to help others see. That it’s possible to step off the hype rails and still thrive.
Bitcoin: The Turning Point
It wasn’t until last fall that Bitcoin truly became central for me.\ Not just part of a portfolio — the lens through which I see capital, time, and truth.
I don’t see it as speculative anymore. I see it as inevitable. In 20–30 years, I believe Bitcoin will be the de facto reserve currency — even if not in name. Those who hold it will steward wealth not because they played the game, but because they opted out of it early.
I’m stacking not to escape — but to prepare. Not to prove I'm right — but to live rightly.
Legacy Without a Platform
I don’t have children.\ But I do have nieces. Nephews. Brothers. Sisters. Cousins. In-Laws.
And I know they’re watching — even if they don’t say it.\ I want to show them that you can live with truth, walk by faith, work with your hands — and still thrive.
I’m not stacking for applause. I’m stacking for legacy.\ I’m building not just for the next quarter — but for the next generation.
And if someone, years from now, asks why I chose this path, I want to say:
Because it was real.\ Because it was proof.\ Because it was built to last.
⚡ If this series has encouraged or challenged you, zap a few sats/bitcoin. It keeps me building.

@ 97c70a44:ad98e322
2025-01-30 17:15:37There was a slight dust up recently over a website someone runs removing a listing for an app someone built based on entirely arbitrary criteria. I'm not to going to attempt to speak for either wounded party, but I would like to share my own personal definition for what constitutes a "nostr app" in an effort to help clarify what might be an otherwise confusing and opaque purity test.
In this post, I will be committing the "no true Scotsman" fallacy, in which I start with the most liberal definition I can come up with, and gradually refine it until all that is left is the purest, gleamingest, most imaginary and unattainable nostr app imaginable. As I write this, I wonder if anything built yet will actually qualify. In any case, here we go.
It uses nostr
The lowest bar for what a "nostr app" might be is an app ("application" - i.e. software, not necessarily a native app of any kind) that has some nostr-specific code in it, but which doesn't take any advantage of what makes nostr distinctive as a protocol.
Examples might include a scraper of some kind which fulfills its charter by fetching data from relays (regardless of whether it validates or retains signatures). Another might be a regular web 2.0 app which provides an option to "log in with nostr" by requesting and storing the user's public key.
In either case, the fact that nostr is involved is entirely neutral. A scraper can scrape html, pdfs, jsonl, whatever data source - nostr relays are just another target. Likewise, a user's key in this scenario is treated merely as an opaque identifier, with no appreciation for the super powers it brings along.
In most cases, this kind of app only exists as a marketing ploy, or less cynically, because it wants to get in on the hype of being a "nostr app", without the developer quite understanding what that means, or having the budget to execute properly on the claim.
It leverages nostr
Some of you might be wondering, "isn't 'leverage' a synonym for 'use'?" And you would be right, but for one connotative difference. It's possible to "use" something improperly, but by definition leverage gives you a mechanical advantage that you wouldn't otherwise have. This is the second category of "nostr app".
This kind of app gets some benefit out of the nostr protocol and network, but in an entirely selfish fashion. The intention of this kind of app is not to augment the nostr network, but to augment its own UX by borrowing some nifty thing from the protocol without really contributing anything back.
Some examples might include:
- Using nostr signers to encrypt or sign data, and then store that data on a proprietary server.
- Using nostr relays as a kind of low-code backend, but using proprietary event payloads.
- Using nostr event kinds to represent data (why), but not leveraging the trustlessness that buys you.
An application in this category might even communicate to its users via nostr DMs - but this doesn't make it a "nostr app" any more than a website that emails you hot deals on herbal supplements is an "email app". These apps are purely parasitic on the nostr ecosystem.
In the long-term, that's not necessarily a bad thing. Email's ubiquity is self-reinforcing. But in the short term, this kind of "nostr app" can actually do damage to nostr's reputation by over-promising and under-delivering.
It complements nostr
Next up, we have apps that get some benefit out of nostr as above, but give back by providing a unique value proposition to nostr users as nostr users. This is a bit of a fine distinction, but for me this category is for apps which focus on solving problems that nostr isn't good at solving, leaving the nostr integration in a secondary or supporting role.
One example of this kind of app was Mutiny (RIP), which not only allowed users to sign in with nostr, but also pulled those users' social graphs so that users could send money to people they knew and trusted. Mutiny was doing a great job of leveraging nostr, as well as providing value to users with nostr identities - but it was still primarily a bitcoin wallet, not a "nostr app" in the purest sense.
Other examples are things like Nostr Nests and Zap.stream, whose core value proposition is streaming video or audio content. Both make great use of nostr identities, data formats, and relays, but they're primarily streaming apps. A good litmus test for things like this is: if you got rid of nostr, would it be the same product (even if inferior in certain ways)?
A similar category is infrastructure providers that benefit nostr by their existence (and may in fact be targeted explicitly at nostr users), but do things in a centralized, old-web way; for example: media hosts, DNS registrars, hosting providers, and CDNs.
To be clear here, I'm not casting aspersions (I don't even know what those are, or where to buy them). All the apps mentioned above use nostr to great effect, and are a real benefit to nostr users. But they are not True Scotsmen.
It embodies nostr
Ok, here we go. This is the crème de la crème, the top du top, the meilleur du meilleur, the bee's knees. The purest, holiest, most chaste category of nostr app out there. The apps which are, indeed, nostr indigitate.
This category of nostr app (see, no quotes this time) can be defined by the converse of the previous category. If nostr was removed from this type of application, would it be impossible to create the same product?
To tease this apart a bit, apps that leverage the technical aspects of nostr are dependent on nostr the protocol, while apps that benefit nostr exclusively via network effect are integrated into nostr the network. An app that does both things is working in symbiosis with nostr as a whole.
An app that embraces both nostr's protocol and its network becomes an organic extension of every other nostr app out there, multiplying both its competitive moat and its contribution to the ecosystem:
- In contrast to apps that only borrow from nostr on the technical level but continue to operate in their own silos, an application integrated into the nostr network comes pre-packaged with existing users, and is able to provide more value to those users because of other nostr products. On nostr, it's a good thing to advertise your competitors.
- In contrast to apps that only market themselves to nostr users without building out a deep integration on the protocol level, a deeply integrated app becomes an asset to every other nostr app by becoming an organic extension of them through interoperability. This results in increased traffic to the app as other developers and users refer people to it instead of solving their problem on their own. This is the "micro-apps" utopia we've all been waiting for.
Credible exit doesn't matter if there aren't alternative services. Interoperability is pointless if other applications don't offer something your app doesn't. Marketing to nostr users doesn't matter if you don't augment their agency as nostr users.
If I had to choose a single NIP that represents the mindset behind this kind of app, it would be NIP 89 A.K.A. "Recommended Application Handlers", which states:
Nostr's discoverability and transparent event interaction is one of its most interesting/novel mechanics. This NIP provides a simple way for clients to discover applications that handle events of a specific kind to ensure smooth cross-client and cross-kind interactions.
These handlers are the glue that holds nostr apps together. A single event, signed by the developer of an application (or by the application's own account) tells anyone who wants to know 1. what event kinds the app supports, 2. how to link to the app (if it's a client), and (if the pubkey also publishes a kind 10002), 3. which relays the app prefers.
As a sidenote, NIP 89 is currently focused more on clients, leaving DVMs, relays, signers, etc somewhat out in the cold. Updating 89 to include tailored listings for each kind of supporting app would be a huge improvement to the protocol. This, plus a good front end for navigating these listings (sorry nostrapp.link, close but no cigar) would obviate the evil centralized websites that curate apps based on arbitrary criteria.
Examples of this kind of app obviously include many kind 1 clients, as well as clients that attempt to bring the benefits of the nostr protocol and network to new use cases - whether long form content, video, image posts, music, emojis, recipes, project management, or any other "content type".
To drill down into one example, let's think for a moment about forms. What's so great about a forms app that is built on nostr? Well,
- There is a spec for forms and responses, which means that...
- Multiple clients can implement the same data format, allowing for credible exit and user choice, even of...
- Other products not focused on forms, which can still view, respond to, or embed forms, and which can send their users via NIP 89 to a client that does...
- Cryptographically sign forms and responses, which means they are self-authenticating and can be sent to...
- Multiple relays, which reduces the amount of trust necessary to be confident results haven't been deliberately "lost".
Show me a forms product that does all of those things, and isn't built on nostr. You can't, because it doesn't exist. Meanwhile, there are plenty of image hosts with APIs, streaming services, and bitcoin wallets which have basically the same levels of censorship resistance, interoperability, and network effect as if they weren't built on nostr.
It supports nostr
Notice I haven't said anything about whether relays, signers, blossom servers, software libraries, DVMs, and the accumulated addenda of the nostr ecosystem are nostr apps. Well, they are (usually).
This is the category of nostr app that gets none of the credit for doing all of the work. There's no question that they qualify as beautiful nostrcorns, because their value propositions are entirely meaningless outside of the context of nostr. Who needs a signer if you don't have a cryptographic identity you need to protect? DVMs are literally impossible to use without relays. How are you going to find the blossom server that will serve a given hash if you don't know which servers the publishing user has selected to store their content?
In addition to being entirely contextualized by nostr architecture, this type of nostr app is valuable because it does things "the nostr way". By that I mean that they don't simply try to replicate existing internet functionality into a nostr context; instead, they create entirely new ways of putting the basic building blocks of the internet back together.
A great example of this is how Nostr Connect, Nostr Wallet Connect, and DVMs all use relays as brokers, which allows service providers to avoid having to accept incoming network connections. This opens up really interesting possibilities all on its own.
So while I might hesitate to call many of these things "apps", they are certainly "nostr".
Appendix: it smells like a NINO
So, let's say you've created an app, but when you show it to people they politely smile, nod, and call it a NINO (Nostr In Name Only). What's a hacker to do? Well, here's your handy-dandy guide on how to wash that NINO stench off and Become a Nostr.
You app might be a NINO if:
- There's no NIP for your data format (or you're abusing NIP 78, 32, etc by inventing a sub-protocol inside an existing event kind)
- There's a NIP, but no one knows about it because it's in a text file on your hard drive (or buried in your project's repository)
- Your NIP imposes an incompatible/centralized/legacy web paradigm onto nostr
- Your NIP relies on trusted third (or first) parties
- There's only one implementation of your NIP (yours)
- Your core value proposition doesn't depend on relays, events, or nostr identities
- One or more relay urls are hard-coded into the source code
- Your app depends on a specific relay implementation to work (ahem, relay29)
- You don't validate event signatures
- You don't publish events to relays you don't control
- You don't read events from relays you don't control
- You use legacy web services to solve problems, rather than nostr-native solutions
- You use nostr-native solutions, but you've hardcoded their pubkeys or URLs into your app
- You don't use NIP 89 to discover clients and services
- You haven't published a NIP 89 listing for your app
- You don't leverage your users' web of trust for filtering out spam
- You don't respect your users' mute lists
- You try to "own" your users' data
Now let me just re-iterate - it's ok to be a NINO. We need NINOs, because nostr can't (and shouldn't) tackle every problem. You just need to decide whether your app, as a NINO, is actually contributing to the nostr ecosystem, or whether you're just using buzzwords to whitewash a legacy web software product.
If you're in the former camp, great! If you're in the latter, what are you waiting for? Only you can fix your NINO problem. And there are lots of ways to do this, depending on your own unique situation:
- Drop nostr support if it's not doing anyone any good. If you want to build a normal company and make some money, that's perfectly fine.
- Build out your nostr integration - start taking advantage of webs of trust, self-authenticating data, event handlers, etc.
- Work around the problem. Think you need a special relay feature for your app to work? Guess again. Consider encryption, AUTH, DVMs, or better data formats.
- Think your idea is a good one? Talk to other devs or open a PR to the nips repo. No one can adopt your NIP if they don't know about it.
- Keep going. It can sometimes be hard to distinguish a research project from a NINO. New ideas have to be built out before they can be fully appreciated.
- Listen to advice. Nostr developers are friendly and happy to help. If you're not sure why you're getting traction, ask!
I sincerely hope this article is useful for all of you out there in NINO land. Maybe this made you feel better about not passing the totally optional nostr app purity test. Or maybe it gave you some actionable next steps towards making a great NINON (Nostr In Not Only Name) app. In either case, GM and PV.

2025-05-11 06:23:03Past week summary
From a Self Custody for Organizations perspective, after analyzing the existing protocols (Cerberus, 10xSecurityBTCguide and Glacier) and reading a bunch of relates articles and guides, have wrapped to the conclusion that this format it is good to have as reference. However, something else is needed. For example, a summary or a map of the whole process to provide an overview, plus a way to deliver all the information and the multy-process in a more enjoyable way. Not a job for this hackathon, but with the right collaborations I assume it's possible to: - build something that might introduce a bit more quests and gamification - provide a learning environment (with testnet funds) could also be crucial on educating those unfamiliar with bitcoin onchain dynamics.
Have been learning more and playing around practicing best accessibility practices and how it could be applied to a desktop software like Bitcoin Safe. Thanks to @johnjherzog for providing a screen recording of his first experience and @jasonb for suggesting the tools to be used. (in this case tested/testing on Windows with the Accessibility Insights app). Some insight shared have been also applied to the website, running a full accessibility check (under WCAG 2.2 ADA, and Section 508 standards) with 4 different plugins and two online tools. I recognize that not all of them works and analyze the same parameters, indeed they complement each other providing a more accurate review.
For Bitcoin Safe interface improvements, many suggestions have been shared with @andreasgriffin , including: - a new iconset, including a micro-set to display the number of confirmed blocs for each transaction - a redesigned History/Dashboard - small refinements like adding missing columns on the tables - allow the user to select which columns to be displayed - sorting of unconfirmed transactions - Defining a new style for design elements like mempool blocks and quick receive boxes You can find below some screenshots with my proposals that hopefully will be included in the next release.
Last achievement this week was to prepare the website https://Safe.BTC.pub, the container where all the outcomes f this experiment will be published. You can have a look, just consider it still WIP. Branding for the project has also been finalized and available in this penpot file https://design.penpot.app/#/workspace?team-id=cec80257-5021-8137-8005-eab60c043dd6&project-id=cec80257-5021-8137-8005-eab60c043dd8&file-id=95aea877-d515-80ac-8006-23a251886db3&page-id=132f519a-39f4-80db-8006-2a41c364a545
What's for next week
After spending most of the time learning and reading material, this coming week will be focused on deliverables. The goal as planned will be to provide: - Finalized Safe₿its brand and improve overall desktop app experience, including categorization of transactions and addresses - An accessibility report or guide for Bitcoin Safe and support to implement best practices - A first draft of the Self-Custody for Organizations guide/framework/protocol, ideally delivered through the website http://Safe.BTC.pub in written format, but also as FlowChart to help have an overview of the whole resources needed and the process itself. This will clearly define preparations and tools/hardwares needed to successfully complete the process.

2025-01-21 23:17:29A seguir, veja como instalar e configurar o Privoxy no Pop!_OS.
1. Instalar o Tor e o Privoxy
Abra o terminal e execute:
bash sudo apt update sudo apt install tor privoxy
Explicação:
- Tor: Roteia o tráfego pela rede Tor.
- Privoxy: Proxy avançado que intermedia a conexão entre aplicativos e o Tor.
2. Configurar o Privoxy
Abra o arquivo de configuração do Privoxy:
bash sudo nano /etc/privoxy/config
Navegue até a última linha (atalho:
Ctrl
+/
depoisCtrl
+V
para navegar diretamente até a última linha) e insira:bash forward-socks5 / 127.0.0.1:9050 .
Isso faz com que o Privoxy envie todo o tráfego para o Tor através da porta 9050.
Salve (
CTRL
+O
eEnter
) e feche (CTRL
+X
) o arquivo.
3. Iniciar o Tor e o Privoxy
Agora, inicie e habilite os serviços:
bash sudo systemctl start tor sudo systemctl start privoxy sudo systemctl enable tor sudo systemctl enable privoxy
Explicação:
- start: Inicia os serviços.
- enable: Faz com que iniciem automaticamente ao ligar o PC.
4. Configurar o Navegador Firefox
Para usar a rede Tor com o Firefox:
- Abra o Firefox.

2025-05-19 20:31:54“ประเด็นแท้จริงคือเรื่องของการควบคุม—อินเทอร์เน็ตแพร่ขยายกว้างไกลเกินกว่าที่รัฐบาลใดจะครอบงำได้โดยง่าย ด้วยการสร้างเขตเศรษฐกิจระดับโลกที่ไร้รอยต่อ ไม่ขึ้นต่ออธิปไตย และอยู่นอกเหนือการควบคุม อินเทอร์เน็ตจึงตั้งคำถามต่อแนวคิดของรัฐชาติในตัวมันเอง” — JOHN PERRY BARLOW
บทนี้เริ่มต้นด้วยการวิพากษ์แนวคิด ทางด่วนข้อมูล ว่าเป็นคำอุปมาอุปมัยที่ยังยึดติดกับโลกยุคอุตสาหกรรม เพราะเศรษฐกิจยุคสารสนเทศไม่ใช่แค่โครงสร้างพื้นฐานสำหรับขนส่งข้อมูล แต่คือ จุดหมายปลายทาง ใหม่ในตัวเอง นั่นคือ ไซเบอร์สเปซ —ดินแดนที่ก้าวข้ามขอบเขตทางภูมิศาสตร์โดยสิ้นเชิง
ไซเบอร์สเปซคือพื้นที่ใหม่ของปฏิสัมพันธ์ทางสังคม เศรษฐกิจ และการเมือง ซึ่งไม่สามารถควบคุมโดยรัฐชาติแบบเดิมได้อีกต่อไป ผู้เขียนยกคำของ John Perry Barlow ที่เปรียบไซเบอร์สเปซเป็น “ดินแดนแห่งเสรีภาพ” ที่ไม่ยึดโยงกับสถานที่จริง และเปิดโอกาสให้ทุกคนแสดงความคิดเห็นได้อย่างไร้การควบคุม
การเปลี่ยนผ่านนี้ส่งผลกระทบรุนแรงต่อโครงสร้างของเศรษฐกิจแบบเดิม การเข้าถึงข้อมูลอย่างรวดเร็วแบบไร้ขอบเขตเปรียบเสมือนตัวทำละลายที่กัดกร่อนต้นทุนของสถาบันขนาดใหญ่ ทั้งภาครัฐและเอกชน ไมโครโพรเซสซิงจะเปลี่ยนรูปแบบขององค์กรและแนวคิดเรื่องสถานที่ในทางเศรษฐกิจอย่างสิ้นเชิง
ตลอดประวัติศาสตร์ เศรษฐกิจผูกติดกับพื้นที่ทางภูมิศาสตร์ การเดินทางเป็นเรื่องยากและจำกัด การค้าขายส่วนใหญ่เกิดในระดับท้องถิ่น ภาษา วัฒนธรรม และภูมิประเทศเป็นอุปสรรคทางการเมืองเสมอ จนถึงกับที่ผู้เขียนกล่าวว่า การเมืองทั้งหมดเป็นเรื่องท้องถิ่น
แต่เทคโนโลยีสมัยใหม่กำลังเปลี่ยนสมการนี้ การสื่อสารและขนส่งที่รวดเร็วทำให้ผู้มีความสามารถสามารถเลือกสถานที่อยู่อาศัยหรือทำงานได้อย่างเสรี ลดอำนาจต่อรองของรัฐบาลในพื้นที่นั้นลง เพราะคนสามารถ “หนี” ได้ง่ายขึ้น หากรัฐบาลกดขี่หรือรีดไถ
แม้อินเทอร์เน็ตยุคแรกจะดูธรรมดา เช่น ใช้อ่านบทความหรือสั่งซื้อสินค้า แต่ศักยภาพที่แท้จริงของเศรษฐกิจไซเบอร์นั้นยิ่งใหญ่มาก ผู้เขียนเสนอว่ามันจะพัฒนาเป็นสามขั้น: 1. ขั้นพื้นฐาน: อินเทอร์เน็ตเป็นเพียงช่องทางเพิ่มประสิทธิภาพธุรกิจแบบเดิม (เช่น เว็บขายสินค้าขายของออนไลน์ เช่น อเมซอน) 2. ขั้นพัฒนา: การเกิดขึ้นของเงินดิจิทัลที่เข้ารหัสและไม่สามารถติดตามได้ จะปลดปล่อยธุรกรรมจากการควบคุมและการจัดเก็บภาษีของรัฐ 3. ขั้นก้าวหน้า: ไซเบอร์สเปซจะมีระบบเศรษฐกิจ กฎหมาย และกลไกคุ้มครองของตัวเอง ปราศจากการควบคุมจากรัฐบาลใด ๆ
ในโลกใหม่นี้ Sovereign Individual หรือ “ปัจเจกผู้มีอธิปไตย” จะสามารถสร้างความมั่งคั่งและดำเนินกิจกรรมในไซเบอร์สเปซได้อย่างเป็นอิสระ โดยไม่ต้องอิงรัฐชาติ รัฐจึงจะถูกบีบให้ลดขนาดและเปลี่ยนบทบาทจากผู้ใช้อำนาจกลายเป็นผู้ให้บริการที่ต้องแข่งขันเพื่อความพึงพอใจของพลเมือง

2025-05-10 09:50:45Information ohne Reflexion ist geistiger Flugsand. \ Ernst Reinhardt
Der lateinische Ausdruck «Quo vadis» als Frage nach einer Entwicklung oder Ausrichtung hat biblische Wurzeln. Er wird aber auch in unserer Alltagssprache verwendet, laut Duden meist als Ausdruck von Besorgnis oder Skepsis im Sinne von: «Wohin wird das führen?»
Der Sinn und Zweck von so mancher politischen Entscheidung erschließt sich heutzutage nicht mehr so leicht, und viele Trends können uns Sorge bereiten. Das sind einerseits sehr konkrete Themen wie die zunehmende Militarisierung und die geschichtsvergessene Kriegstreiberei in Europa, deren Feindbildpflege aktuell beim Gedenken an das Ende des Zweiten Weltkriegs beschämende Formen annimmt.
Auch das hohe Gut der Schweizer Neutralität scheint immer mehr in Gefahr. Die schleichende Bewegung der Eidgenossenschaft in Richtung NATO und damit weg von einer Vermittlerposition erhält auch durch den neuen Verteidigungsminister Anschub. Martin Pfister möchte eine stärkere Einbindung in die europäische Verteidigungsarchitektur, verwechselt bei der Argumentation jedoch Ursache und Wirkung.
Das Thema Gesundheit ist als Zugpferd für Geschäfte und Kontrolle offenbar schon zuverlässig etabliert. Die hauptsächlich privat finanzierte Weltgesundheitsorganisation (WHO) ist dabei durch ein Netzwerk von sogenannten «Collaborating Centres» sogar so weit in nationale Einrichtungen eingedrungen, dass man sich fragen kann, ob diese nicht von Genf aus gesteuert werden.
Das Schweizer Bundesamt für Gesundheit (BAG) übernimmt in dieser Funktion ebenso von der WHO definierte Aufgaben und Pflichten wie das deutsche Robert Koch-Institut (RKI). Gegen die Covid-«Impfung» für Schwangere, die das BAG empfiehlt, obwohl es fehlende wissenschaftliche Belege für deren Schutzwirkung einräumt, formiert sich im Tessin gerade Widerstand.
Unter dem Stichwort «Gesundheitssicherheit» werden uns die Bestrebungen verkauft, essenzielle Dienste mit einer biometrischen digitalen ID zu verknüpfen. Das dient dem Profit mit unseren Daten und führt im Ergebnis zum Verlust unserer demokratischen Freiheiten. Die deutsche elektronische Patientenakte (ePA) ist ein Element mit solchem Potenzial. Die Schweizer Bürger haben gerade ein Referendum gegen das revidierte E-ID-Gesetz erzwungen. In Thailand ist seit Anfang Mai für die Einreise eine «Digital Arrival Card» notwendig, die mit ihrer Gesundheitserklärung einen Impfpass «durch die Hintertür» befürchten lässt.
Der massive Blackout auf der iberischen Halbinsel hat vermehrt Fragen dazu aufgeworfen, wohin uns Klimawandel-Hysterie und «grüne» Energiepolitik führen werden. Meine Kollegin Wiltrud Schwetje ist dem nachgegangen und hat in mehreren Beiträgen darüber berichtet. Wenig überraschend führen interessante Spuren mal wieder zu internationalen Großbanken, Globalisten und zur EU-Kommission.
Zunehmend bedenklich ist aber ganz allgemein auch die manifestierte Spaltung unserer Gesellschaften. Angesichts der tiefen und sorgsam gepflegten Gräben fällt es inzwischen schwer, eine zukunftsfähige Perspektive zu erkennen. Umso begrüßenswerter sind Initiativen wie die Kölner Veranstaltungsreihe «Neue Visionen für die Zukunft». Diese möchte die Diskussionskultur reanimieren und dazu beitragen, dass Menschen wieder ohne Angst und ergebnisoffen über kontroverse Themen der Zeit sprechen.
Quo vadis – Wohin gehen wir also? Die Suche nach Orientierung in diesem vermeintlichen Chaos führt auch zur Reflexion über den eigenen Lebensweg. Das ist positiv insofern, als wir daraus Kraft schöpfen können. Ob derweil der neue Papst, dessen «Vorgänger» Petrus unsere Ausgangsfrage durch die christliche Legende zugeschrieben wird, dabei eine Rolle spielt, muss jede/r selbst wissen. Mir persönlich ist allein schon ein Führungsanspruch wie der des Petrusprimats der römisch-katholischen Kirche eher suspekt.

— Bitcoin Magazine (@BitcoinMagazine) May 19, 2025
This weekly close sets a new benchmark for BTC’s price performance and positions the asset in a historically rare range. As of Monday, Bitcoin is trading at $102,924, reflecting typical price movement following a new high as markets adjust to key levels.
Historical data helps illustrate the significance of this moment. According to an analysis shared by on-chain researcher Dan, Bitcoin has closed above $106,439 only once—this week—accounting for just 0.02% of its entire trading history. Closures above $100,000 have occurred in only 40 days total. Even levels like $75,000 and $50,000 remain relatively uncommon in Bitcoin’s lifespan, appearing on just 181 and 586 days, respectively.
— Dan (@robustus) May 19, 2025
This data highlights how current prices place Bitcoin in a historically narrow range of time — a reflection of the long-term upward trend of the asset over the past decade. For market participants, this type of price action often serves as an indicator of continued momentum and interest in Bitcoin’s role as a digital store of value.
The broader Bitcoin ecosystem continues to show strength, with on-chain metrics reflecting growing user engagement and long-term holder confidence. Notably, activity on the Bitcoin network remains elevated, with transaction volumes and address growth signaling continued adoption. Analysts are closely watching inflows into Bitcoin-focused ETFs and the behavior of long-term holders, both of which are key indicators of sustained interest and belief in Bitcoin’s long-term value.

We'll probably be done with the 2nd round, by the time we record, which means round 2 recap and conference finals previews. It's definitely not the matchups anyone expected. What are the implications for our brackets?
The NFL released the season schedules and @grayruby's rightly excited for his 49ers upcoming season.
The parity situation worsens in the MLB, as the Dodgers' pitchers are ravaged by injury. Also, @grayruby and I are going head-to-head in fantasy baseball this week. Who will prevail?
On this week's Blok'd Shots, @grayruby will dance on the Leafs' grave and celebrate their well-deserved misfortune. Hell hath no fury like a scorned Leafs fan. Also, the NHL bracket is coming down to me and @Jer. Will knowing anything about hockey be enough to get Jer the victory?

For generations before generative text, writers have used the em dash to hop between thoughts, emotions, and ideas. Dickens shaped his morality tales with it, Woolf’s stream-of-consciousness flowed through it, Kerouac let it drive his jazz-like prose. Today, Sally Rooney threads it through her quiet truths of the heart.
But this beloved punctuation mark has become a casualty of the algorithmic age. The em dash has been so widely adopted by AI-generated text that even when used by human hands, it begs the question: was this actually written or apathetically prompted?
The battle for the soul of writing is in full swing. And the human fightback starts here. With a new punctuation mark that serves as a symbol of real pondering, genuine daydreaming, and true editorial wordsmithery. Inspired by Descartes’ belief that thinking makes us human, the am dash is a small but powerful testament that the words you’ve painstakingly and poetically pulled together are unequivocally, certifiably, and delightfully your own.
Let's reclain writig from AI—oneam dash at time.

2025-05-10 05:11:27Consider the following two charts from A History of Clojure which detail the introduction and retention of new code by release for both Clojure and for Scala.
While this doesn't necessarily translate to library stability, it's reasonable to assume that the attitude of the Clojure maintainers will seep into the community. And that assumption is true.
Consider a typical Javascript program. What is it comprised of? Objects, objects, and more objects. Members of those objects must be either introspected or divined. Worse, it's normal to monkeypatch those objects, so the object members may (or may not) change over time.
Now, consider a typical Clojure program. What is it comprised of? Namespaces. Those namespaces contain functions and data. Functions may be dynamically generated (via macros), but it is extremely rare to "monkeypatch" a namespace. If you want to know what functions are available in a namespace, you can simply read the source file.

2025-01-21 01:51:46Bitcoin: Um sistema de dinheiro eletrônico direto entre pessoas.
Satoshi Nakamoto
satoshin@gmx.com
www.bitcoin.org
Resumo
O Bitcoin é uma forma de dinheiro digital que permite pagamentos diretos entre pessoas, sem a necessidade de um banco ou instituição financeira. Ele resolve um problema chamado gasto duplo, que ocorre quando alguém tenta gastar o mesmo dinheiro duas vezes. Para evitar isso, o Bitcoin usa uma rede descentralizada onde todos trabalham juntos para verificar e registrar as transações.
As transações são registradas em um livro público chamado blockchain, protegido por uma técnica chamada Prova de Trabalho. Essa técnica cria uma cadeia de registros que não pode ser alterada sem refazer todo o trabalho já feito. Essa cadeia é mantida pelos computadores que participam da rede, e a mais longa é considerada a verdadeira.
Enquanto a maior parte do poder computacional da rede for controlada por participantes honestos, o sistema continuará funcionando de forma segura. A rede é flexível, permitindo que qualquer pessoa entre ou saia a qualquer momento, sempre confiando na cadeia mais longa como prova do que aconteceu.
1. Introdução
Hoje, quase todos os pagamentos feitos pela internet dependem de bancos ou empresas como processadores de pagamento (cartões de crédito, por exemplo) para funcionar. Embora esse sistema seja útil, ele tem problemas importantes porque é baseado em confiança.
Primeiro, essas empresas podem reverter pagamentos, o que é útil em caso de erros, mas cria custos e incertezas. Isso faz com que pequenas transações, como pagar centavos por um serviço, se tornem inviáveis. Além disso, os comerciantes são obrigados a desconfiar dos clientes, pedindo informações extras e aceitando fraudes como algo inevitável.
Esses problemas não existem no dinheiro físico, como o papel-moeda, onde o pagamento é final e direto entre as partes. No entanto, não temos como enviar dinheiro físico pela internet sem depender de um intermediário confiável.
O que precisamos é de um sistema de pagamento eletrônico baseado em provas matemáticas, não em confiança. Esse sistema permitiria que qualquer pessoa enviasse dinheiro diretamente para outra, sem depender de bancos ou processadores de pagamento. Além disso, as transações seriam irreversíveis, protegendo vendedores contra fraudes, mas mantendo a possibilidade de soluções para disputas legítimas.
Neste documento, apresentamos o Bitcoin, que resolve o problema do gasto duplo usando uma rede descentralizada. Essa rede cria um registro público e protegido por cálculos matemáticos, que garante a ordem das transações. Enquanto a maior parte da rede for controlada por pessoas honestas, o sistema será seguro contra ataques.
2. Transações
Para entender como funciona o Bitcoin, é importante saber como as transações são realizadas. Imagine que você quer transferir uma "moeda digital" para outra pessoa. No sistema do Bitcoin, essa "moeda" é representada por uma sequência de registros que mostram quem é o atual dono. Para transferi-la, você adiciona um novo registro comprovando que agora ela pertence ao próximo dono. Esse registro é protegido por um tipo especial de assinatura digital.
O que é uma assinatura digital?
Uma assinatura digital é como uma senha secreta, mas muito mais segura. No Bitcoin, cada usuário tem duas chaves: uma "chave privada", que é secreta e serve para criar a assinatura, e uma "chave pública", que pode ser compartilhada com todos e é usada para verificar se a assinatura é válida. Quando você transfere uma moeda, usa sua chave privada para assinar a transação, provando que você é o dono. A próxima pessoa pode usar sua chave pública para confirmar isso.
Como funciona na prática?
Cada "moeda" no Bitcoin é, na verdade, uma cadeia de assinaturas digitais. Vamos imaginar o seguinte cenário:
- A moeda está com o Dono 0 (você). Para transferi-la ao Dono 1, você assina digitalmente a transação com sua chave privada. Essa assinatura inclui o código da transação anterior (chamado de "hash") e a chave pública do Dono 1.
- Quando o Dono 1 quiser transferir a moeda ao Dono 2, ele assinará a transação seguinte com sua própria chave privada, incluindo também o hash da transação anterior e a chave pública do Dono 2.
- Esse processo continua, formando uma "cadeia" de transações. Qualquer pessoa pode verificar essa cadeia para confirmar quem é o atual dono da moeda.
Resolvendo o problema do gasto duplo
Um grande desafio com moedas digitais é o "gasto duplo", que é quando uma mesma moeda é usada em mais de uma transação. Para evitar isso, muitos sistemas antigos dependiam de uma entidade central confiável, como uma casa da moeda, que verificava todas as transações. No entanto, isso criava um ponto único de falha e centralizava o controle do dinheiro.
O Bitcoin resolve esse problema de forma inovadora: ele usa uma rede descentralizada onde todos os participantes (os "nós") têm acesso a um registro completo de todas as transações. Cada nó verifica se as transações são válidas e se a moeda não foi gasta duas vezes. Quando a maioria dos nós concorda com a validade de uma transação, ela é registrada permanentemente na blockchain.
Por que isso é importante?
Essa solução elimina a necessidade de confiar em uma única entidade para gerenciar o dinheiro, permitindo que qualquer pessoa no mundo use o Bitcoin sem precisar de permissão de terceiros. Além disso, ela garante que o sistema seja seguro e resistente a fraudes.
3. Servidor Timestamp
Para assegurar que as transações sejam realizadas de forma segura e transparente, o sistema Bitcoin utiliza algo chamado de "servidor de registro de tempo" (timestamp). Esse servidor funciona como um registro público que organiza as transações em uma ordem específica.
Ele faz isso agrupando várias transações em blocos e criando um código único chamado "hash". Esse hash é como uma impressão digital que representa todo o conteúdo do bloco. O hash de cada bloco é amplamente divulgado, como se fosse publicado em um jornal ou em um fórum público.
Esse processo garante que cada bloco de transações tenha um registro de quando foi criado e que ele existia naquele momento. Além disso, cada novo bloco criado contém o hash do bloco anterior, formando uma cadeia contínua de blocos conectados — conhecida como blockchain.
Com isso, se alguém tentar alterar qualquer informação em um bloco anterior, o hash desse bloco mudará e não corresponderá ao hash armazenado no bloco seguinte. Essa característica torna a cadeia muito segura, pois qualquer tentativa de fraude seria imediatamente detectada.
O sistema de timestamps é essencial para provar a ordem cronológica das transações e garantir que cada uma delas seja única e autêntica. Dessa forma, ele reforça a segurança e a confiança na rede Bitcoin.
4. Prova-de-Trabalho
Para implementar o registro de tempo distribuído no sistema Bitcoin, utilizamos um mecanismo chamado prova-de-trabalho. Esse sistema é semelhante ao Hashcash, desenvolvido por Adam Back, e baseia-se na criação de um código único, o "hash", por meio de um processo computacionalmente exigente.
A prova-de-trabalho envolve encontrar um valor especial que, quando processado junto com as informações do bloco, gere um hash que comece com uma quantidade específica de zeros. Esse valor especial é chamado de "nonce". Encontrar o nonce correto exige um esforço significativo do computador, porque envolve tentativas repetidas até que a condição seja satisfeita.
Esse processo é importante porque torna extremamente difícil alterar qualquer informação registrada em um bloco. Se alguém tentar mudar algo em um bloco, seria necessário refazer o trabalho de computação não apenas para aquele bloco, mas também para todos os blocos que vêm depois dele. Isso garante a segurança e a imutabilidade da blockchain.
A prova-de-trabalho também resolve o problema de decidir qual cadeia de blocos é a válida quando há múltiplas cadeias competindo. A decisão é feita pela cadeia mais longa, pois ela representa o maior esforço computacional já realizado. Isso impede que qualquer indivíduo ou grupo controle a rede, desde que a maioria do poder de processamento seja mantida por participantes honestos.
Para garantir que o sistema permaneça eficiente e equilibrado, a dificuldade da prova-de-trabalho é ajustada automaticamente ao longo do tempo. Se novos blocos estiverem sendo gerados rapidamente, a dificuldade aumenta; se estiverem sendo gerados muito lentamente, a dificuldade diminui. Esse ajuste assegura que novos blocos sejam criados aproximadamente a cada 10 minutos, mantendo o sistema estável e funcional.
5. Rede
A rede Bitcoin é o coração do sistema e funciona de maneira distribuída, conectando vários participantes (ou nós) para garantir o registro e a validação das transações. Os passos para operar essa rede são:
-
Transmissão de Transações: Quando alguém realiza uma nova transação, ela é enviada para todos os nós da rede. Isso é feito para garantir que todos estejam cientes da operação e possam validá-la.
-
Coleta de Transações em Blocos: Cada nó agrupa as novas transações recebidas em um "bloco". Este bloco será preparado para ser adicionado à cadeia de blocos (a blockchain).
-
Prova-de-Trabalho: Os nós competem para resolver a prova-de-trabalho do bloco, utilizando poder computacional para encontrar um hash válido. Esse processo é como resolver um quebra-cabeça matemático difícil.
-
Envio do Bloco Resolvido: Quando um nó encontra a solução para o bloco (a prova-de-trabalho), ele compartilha esse bloco com todos os outros nós na rede.
-
Validação do Bloco: Cada nó verifica o bloco recebido para garantir que todas as transações nele contidas sejam válidas e que nenhuma moeda tenha sido gasta duas vezes. Apenas blocos válidos são aceitos.
-
Construção do Próximo Bloco: Os nós que aceitaram o bloco começam a trabalhar na criação do próximo bloco, utilizando o hash do bloco aceito como base (hash anterior). Isso mantém a continuidade da cadeia.
Resolução de Conflitos e Escolha da Cadeia Mais Longa
Os nós sempre priorizam a cadeia mais longa, pois ela representa o maior esforço computacional já realizado, garantindo maior segurança. Se dois blocos diferentes forem compartilhados simultaneamente, os nós trabalharão no primeiro bloco recebido, mas guardarão o outro como uma alternativa. Caso o segundo bloco eventualmente forme uma cadeia mais longa (ou seja, tenha mais blocos subsequentes), os nós mudarão para essa nova cadeia.
Tolerância a Falhas
A rede é robusta e pode lidar com mensagens que não chegam a todos os nós. Uma transação não precisa alcançar todos os nós de imediato; basta que chegue a um número suficiente deles para ser incluída em um bloco. Da mesma forma, se um nó não receber um bloco em tempo hábil, ele pode solicitá-lo ao perceber que está faltando quando o próximo bloco é recebido.
Esse mecanismo descentralizado permite que a rede Bitcoin funcione de maneira segura, confiável e resiliente, sem depender de uma autoridade central.
6. Incentivo
O incentivo é um dos pilares fundamentais que sustenta o funcionamento da rede Bitcoin, garantindo que os participantes (nós) continuem operando de forma honesta e contribuindo com recursos computacionais. Ele é estruturado em duas partes principais: a recompensa por mineração e as taxas de transação.
Recompensa por Mineração
Por convenção, o primeiro registro em cada bloco é uma transação especial que cria novas moedas e as atribui ao criador do bloco. Essa recompensa incentiva os mineradores a dedicarem poder computacional para apoiar a rede. Como não há uma autoridade central para emitir moedas, essa é a maneira pela qual novas moedas entram em circulação. Esse processo pode ser comparado ao trabalho de garimpeiros, que utilizam recursos para colocar mais ouro em circulação. No caso do Bitcoin, o "recurso" consiste no tempo de CPU e na energia elétrica consumida para resolver a prova-de-trabalho.
Taxas de Transação
Além da recompensa por mineração, os mineradores também podem ser incentivados pelas taxas de transação. Se uma transação utiliza menos valor de saída do que o valor de entrada, a diferença é tratada como uma taxa, que é adicionada à recompensa do bloco contendo essa transação. Com o passar do tempo e à medida que o número de moedas em circulação atinge o limite predeterminado, essas taxas de transação se tornam a principal fonte de incentivo, substituindo gradualmente a emissão de novas moedas. Isso permite que o sistema opere sem inflação, uma vez que o número total de moedas permanece fixo.
Incentivo à Honestidade
O design do incentivo também busca garantir que os participantes da rede mantenham um comportamento honesto. Para um atacante que consiga reunir mais poder computacional do que o restante da rede, ele enfrentaria duas escolhas:
- Usar esse poder para fraudar o sistema, como reverter transações e roubar pagamentos.
- Seguir as regras do sistema, criando novos blocos e recebendo recompensas legítimas.
A lógica econômica favorece a segunda opção, pois um comportamento desonesto prejudicaria a confiança no sistema, diminuindo o valor de todas as moedas, incluindo aquelas que o próprio atacante possui. Jogar dentro das regras não apenas maximiza o retorno financeiro, mas também preserva a validade e a integridade do sistema.
Esse mecanismo garante que os incentivos econômicos estejam alinhados com o objetivo de manter a rede segura, descentralizada e funcional ao longo do tempo.
7. Recuperação do Espaço em Disco
Depois que uma moeda passa a estar protegida por muitos blocos na cadeia, as informações sobre as transações antigas que a geraram podem ser descartadas para economizar espaço em disco. Para que isso seja possível sem comprometer a segurança, as transações são organizadas em uma estrutura chamada "árvore de Merkle". Essa árvore funciona como um resumo das transações: em vez de armazenar todas elas, guarda apenas um "hash raiz", que é como uma assinatura compacta que representa todo o grupo de transações.
Os blocos antigos podem, então, ser simplificados, removendo as partes desnecessárias dessa árvore. Apenas a raiz do hash precisa ser mantida no cabeçalho do bloco, garantindo que a integridade dos dados seja preservada, mesmo que detalhes específicos sejam descartados.
Para exemplificar: imagine que você tenha vários recibos de compra. Em vez de guardar todos os recibos, você cria um documento e lista apenas o valor total de cada um. Mesmo que os recibos originais sejam descartados, ainda é possível verificar a soma com base nos valores armazenados.
Além disso, o espaço ocupado pelos blocos em si é muito pequeno. Cada bloco sem transações ocupa apenas cerca de 80 bytes. Isso significa que, mesmo com blocos sendo gerados a cada 10 minutos, o crescimento anual em espaço necessário é insignificante: apenas 4,2 MB por ano. Com a capacidade de armazenamento dos computadores crescendo a cada ano, esse espaço continuará sendo trivial, garantindo que a rede possa operar de forma eficiente sem problemas de armazenamento, mesmo a longo prazo.
8. Verificação de Pagamento Simplificada
É possível confirmar pagamentos sem a necessidade de operar um nó completo da rede. Para isso, o usuário precisa apenas de uma cópia dos cabeçalhos dos blocos da cadeia mais longa (ou seja, a cadeia com maior esforço de trabalho acumulado). Ele pode verificar a validade de uma transação ao consultar os nós da rede até obter a confirmação de que tem a cadeia mais longa. Para isso, utiliza-se o ramo Merkle, que conecta a transação ao bloco em que ela foi registrada.
Entretanto, o método simplificado possui limitações: ele não pode confirmar uma transação isoladamente, mas sim assegurar que ela ocupa um lugar específico na cadeia mais longa. Dessa forma, se um nó da rede aprova a transação, os blocos subsequentes reforçam essa aceitação.
A verificação simplificada é confiável enquanto a maioria dos nós da rede for honesta. Contudo, ela se torna vulnerável caso a rede seja dominada por um invasor. Nesse cenário, um atacante poderia fabricar transações fraudulentas que enganariam o usuário temporariamente até que o invasor obtivesse controle completo da rede.
Uma estratégia para mitigar esse risco é configurar alertas nos softwares de nós completos. Esses alertas identificam blocos inválidos, sugerindo ao usuário baixar o bloco completo para confirmar qualquer inconsistência. Para maior segurança, empresas que realizam pagamentos frequentes podem preferir operar seus próprios nós, reduzindo riscos e permitindo uma verificação mais direta e confiável.
9. Combinando e Dividindo Valor
No sistema Bitcoin, cada unidade de valor é tratada como uma "moeda" individual, mas gerenciar cada centavo como uma transação separada seria impraticável. Para resolver isso, o Bitcoin permite que valores sejam combinados ou divididos em transações, facilitando pagamentos de qualquer valor.
Entradas e Saídas
Cada transação no Bitcoin é composta por:
- Entradas: Representam os valores recebidos em transações anteriores.
- Saídas: Correspondem aos valores enviados, divididos entre os destinatários e, eventualmente, o troco para o remetente.
Normalmente, uma transação contém:
- Uma única entrada com valor suficiente para cobrir o pagamento.
- Ou várias entradas combinadas para atingir o valor necessário.
O valor total das saídas nunca excede o das entradas, e a diferença (se houver) pode ser retornada ao remetente como troco.
Exemplo Prático
Imagine que você tem duas entradas:
- 0,03 BTC
- 0,07 BTC
Se deseja enviar 0,08 BTC para alguém, a transação terá:
- Entrada: As duas entradas combinadas (0,03 + 0,07 BTC = 0,10 BTC).
- Saídas: Uma para o destinatário (0,08 BTC) e outra como troco para você (0,02 BTC).
Essa flexibilidade permite que o sistema funcione sem precisar manipular cada unidade mínima individualmente.
Difusão e Simplificação
A difusão de transações, onde uma depende de várias anteriores e assim por diante, não representa um problema. Não é necessário armazenar ou verificar o histórico completo de uma transação para utilizá-la, já que o registro na blockchain garante sua integridade.
10. Privacidade
O modelo bancário tradicional oferece um certo nível de privacidade, limitando o acesso às informações financeiras apenas às partes envolvidas e a um terceiro confiável (como bancos ou instituições financeiras). No entanto, o Bitcoin opera de forma diferente, pois todas as transações são publicamente registradas na blockchain. Apesar disso, a privacidade pode ser mantida utilizando chaves públicas anônimas, que desvinculam diretamente as transações das identidades das partes envolvidas.
Fluxo de Informação
- No modelo tradicional, as transações passam por um terceiro confiável que conhece tanto o remetente quanto o destinatário.
- No Bitcoin, as transações são anunciadas publicamente, mas sem revelar diretamente as identidades das partes. Isso é comparável a dados divulgados por bolsas de valores, onde informações como o tempo e o tamanho das negociações (a "fita") são públicas, mas as identidades das partes não.
Protegendo a Privacidade
Para aumentar a privacidade no Bitcoin, são adotadas as seguintes práticas:
- Chaves Públicas Anônimas: Cada transação utiliza um par de chaves diferentes, dificultando a associação com um proprietário único.
- Prevenção de Ligação: Ao usar chaves novas para cada transação, reduz-se a possibilidade de links evidentes entre múltiplas transações realizadas pelo mesmo usuário.
Riscos de Ligação
Embora a privacidade seja fortalecida, alguns riscos permanecem:
- Transações multi-entrada podem revelar que todas as entradas pertencem ao mesmo proprietário, caso sejam necessárias para somar o valor total.
- O proprietário da chave pode ser identificado indiretamente por transações anteriores que estejam conectadas.
11. Cálculos
Imagine que temos um sistema onde as pessoas (ou computadores) competem para adicionar informações novas (blocos) a um grande registro público (a cadeia de blocos ou blockchain). Este registro é como um livro contábil compartilhado, onde todos podem verificar o que está escrito.
Agora, vamos pensar em um cenário: um atacante quer enganar o sistema. Ele quer mudar informações já registradas para beneficiar a si mesmo, por exemplo, desfazendo um pagamento que já fez. Para isso, ele precisa criar uma versão alternativa do livro contábil (a cadeia de blocos dele) e convencer todos os outros participantes de que essa versão é a verdadeira.
Mas isso é extremamente difícil.
Como o Ataque Funciona
Quando um novo bloco é adicionado à cadeia, ele depende de cálculos complexos que levam tempo e esforço. Esses cálculos são como um grande quebra-cabeça que precisa ser resolvido.
- Os “bons jogadores” (nós honestos) estão sempre trabalhando juntos para resolver esses quebra-cabeças e adicionar novos blocos à cadeia verdadeira.
- O atacante, por outro lado, precisa resolver quebra-cabeças sozinho, tentando “alcançar” a cadeia honesta para que sua versão alternativa pareça válida.
Se a cadeia honesta já está vários blocos à frente, o atacante começa em desvantagem, e o sistema está projetado para que a dificuldade de alcançá-los aumente rapidamente.
A Corrida Entre Cadeias
Você pode imaginar isso como uma corrida. A cada bloco novo que os jogadores honestos adicionam à cadeia verdadeira, eles se distanciam mais do atacante. Para vencer, o atacante teria que resolver os quebra-cabeças mais rápido que todos os outros jogadores honestos juntos.
Suponha que:
- A rede honesta tem 80% do poder computacional (ou seja, resolve 8 de cada 10 quebra-cabeças).
- O atacante tem 20% do poder computacional (ou seja, resolve 2 de cada 10 quebra-cabeças).
Cada vez que a rede honesta adiciona um bloco, o atacante tem que "correr atrás" e resolver mais quebra-cabeças para alcançar.
Por Que o Ataque Fica Cada Vez Mais Improvável?
Vamos usar uma fórmula simples para mostrar como as chances de sucesso do atacante diminuem conforme ele precisa "alcançar" mais blocos:
P = (q/p)^z
- q é o poder computacional do atacante (20%, ou 0,2).
- p é o poder computacional da rede honesta (80%, ou 0,8).
- z é a diferença de blocos entre a cadeia honesta e a cadeia do atacante.
Se o atacante está 5 blocos atrás (z = 5):
P = (0,2 / 0,8)^5 = (0,25)^5 = 0,00098, (ou, 0,098%)
Isso significa que o atacante tem menos de 0,1% de chance de sucesso — ou seja, é muito improvável.
Se ele estiver 10 blocos atrás (z = 10):
P = (0,2 / 0,8)^10 = (0,25)^10 = 0,000000095, (ou, 0,0000095%).
Neste caso, as chances de sucesso são praticamente nulas.
Um Exemplo Simples
Se você jogar uma moeda, a chance de cair “cara” é de 50%. Mas se precisar de 10 caras seguidas, sua chance já é bem menor. Se precisar de 20 caras seguidas, é quase impossível.
No caso do Bitcoin, o atacante precisa de muito mais do que 20 caras seguidas. Ele precisa resolver quebra-cabeças extremamente difíceis e alcançar os jogadores honestos que estão sempre à frente. Isso faz com que o ataque seja inviável na prática.
Por Que Tudo Isso é Seguro?
- A probabilidade de sucesso do atacante diminui exponencialmente. Isso significa que, quanto mais tempo passa, menor é a chance de ele conseguir enganar o sistema.
- A cadeia verdadeira (honesta) está protegida pela força da rede. Cada novo bloco que os jogadores honestos adicionam à cadeia torna mais difícil para o atacante alcançar.
E Se o Atacante Tentar Continuar?
O atacante poderia continuar tentando indefinidamente, mas ele estaria gastando muito tempo e energia sem conseguir nada. Enquanto isso, os jogadores honestos estão sempre adicionando novos blocos, tornando o trabalho do atacante ainda mais inútil.
Assim, o sistema garante que a cadeia verdadeira seja extremamente segura e que ataques sejam, na prática, impossíveis de ter sucesso.
12. Conclusão
Propusemos um sistema de transações eletrônicas que elimina a necessidade de confiança, baseando-se em assinaturas digitais e em uma rede peer-to-peer que utiliza prova de trabalho. Isso resolve o problema do gasto duplo, criando um histórico público de transações imutável, desde que a maioria do poder computacional permaneça sob controle dos participantes honestos. A rede funciona de forma simples e descentralizada, com nós independentes que não precisam de identificação ou coordenação direta. Eles entram e saem livremente, aceitando a cadeia de prova de trabalho como registro do que ocorreu durante sua ausência. As decisões são tomadas por meio do poder de CPU, validando blocos legítimos, estendendo a cadeia e rejeitando os inválidos. Com este mecanismo de consenso, todas as regras e incentivos necessários para o funcionamento seguro e eficiente do sistema são garantidos.

JPMorgan To Allow Clients To Buy Bitcoin, Jamie Dimon SaysToday, Chairman and CEO of JPMorgan Chase Jamie Dimon reiterated his personal disapproval of Bitcoin during the bank’s annual Investor Day event. Despite the bank’s decision to provide clients with access to Bitcoin investments, Dimon emphasized his personal disapproval of Bitcoin.
“I am not a fan” of Bitcoin, stated Dimon.
JPMorgan is going to allow clients to buy Bitcoin, but the bank won’t custody it, according to Bloomberg. Dimon made clear that while JPMorgan will provide clients access to Bitcoin investments, the bank will not hold or manage the digital asset directly.

In a January 2025 interview with CBS News, Dimon expressed continued skepticism toward Bitcoin. “Bitcoin itself has no intrinsic value. It’s used heavily by sex traffickers, money launderers, ransomware,” said Dimon.
Although he acknowledged, “We are going to have some kind of digital currency at some point,” he added, “I just don’t feel great about bitcoin. I applaud your ability to wanna buy or sell it. Just like I think you have the right to smoke, but I don’t think you should smoke.”
These comments from Dimon contrast with recent optimism from JPMorgan analysts regarding Bitcoin’s market prospects. JPMorgan analysts reported that Bitcoin is likely to continue gaining ground at gold’s expense in the second half of the year, driven by rising corporate demand and growing support from U.S. states.

“Between mid-February and mid-April gold was rising at the expense of bitcoin, while of the past three weeks we have been observing the opposite, i.e. bitcoin rising at the expense of gold,” said JPMorgan analysts. “In all, we expect the YTD zero sum game between gold and bitcoin to extend to the remainder of the year, but are biased towards crypto-specific catalysts creating more upside for bitcoin over gold into the second half of the year.”
Since April 22, gold has dropped nearly 8%, while Bitcoin has surged 18%, reflecting a notable shift in investor sentiment. Capital has been moving out of gold ETFs and into Bitcoin. Several U.S. states are also warming to Bitcoin—New Hampshire now permits up to 5% of its reserves in Bitcoin, while Arizona is launching a Bitcoin reserve and has pledged not to raise taxes this year. At the corporate level, companies like Strategy and Metaplanet are expanding their Bitcoin holdings.
“As the list grows, with other U.S. states potentially considering adding bitcoin to their strategic reserves, this could turn out to be a more sustained positive catalyst for bitcoin,” said the analysts.

2025-05-08 05:25:48Safe Bits & Self Custody Tips
The journey of onboarding a user and create a bitcoin multiSig setup begins far before opening a desktop like Bitcoin Safe (BS) or any other similar application. Bitcoin Safe seems designed for families and people that want to start exploring and learning about multiSig setup. The need for such application and use of it could go much further, defining best practices for private organizations that aim to custody bitcoin in a private and anonymous way, following and enjoy the values and standards bitcoin has been built for.
Intro
Organizations and small private groups like families, family offices and solopreneurs operating on a bitcoin standard will have the need to keep track of transactions and categorize them to keep the books in order. A part of our efforts will be spent ensuring accessibility standards are in place for everyone to use Bitcoin Safe with comfort and safety.
We aim with this project to bring together the three Designathon ideas below: - Bitcoin Safe: improve its overall design and usability. - No User Left Behind: improve Bitcoin Safe accessibility. - Self-custody guidelines for organizations: How Bitcoin Safe can be used by private organization following best self-custody practices.
We are already halfway of the first week, and here below the progress made so far.
Designing an icon Set for Bitcoin Safe
One of the noticeable things when using BS is the inconsistency of the icons, not just in colors and shapes, but also the way are used. The desktop app try to have a clean design that incorporate with all OS (Win, macOS, Linux) and for this reason it's hard to define when a system default icon need to be used or if a custom one can be applied instead. The use of QT Ui framework for python apps help to respond to these questions. It also incorporates and brig up dome default settings that aren't easily overwritten.
Here below you can see the current version of BS:
Defining a more strict color palette for Bitcoin Safe was the first thing!
How much the icons affect accessibility? How they can help users to reach the right functionality? I took the challenge and, with PenPot.app, redesigned the icons based on the grid defined in the https://bitcoinicons.com/ and proposing the implementation of it to have a cleaner and more consistent look'n feel, at least for the icons now.
What's next
I personally look forward to seeing these icons implemented soon in Bitcoin Safe interface. In the meantime, we'll focus on delivering an accessibility audit and evaluate options to see how BS could be used by private organizations aiming to become financially sovereign with self-custody or more complex bitcoin multiSig setups.
One of the greatest innovations BS is bringing to us is the ability to sync the multiSig wallets, including PBST, Categories and labels, through the nostr decentralized protocol, making current key custodial services somehow obsolete. Second-coolest feature that this nostr implementation brings is the ability to have a build-in private chat that connect and enable the various signers of a multiSig to communicate and sign transactions remotely. Where have you seen something like this before?
Categories UX and redesign is also considered in this project. We'll try to understand how to better serve this functionality to you, the user, really soon.
Stay tuned!

2025-05-19 17:38:59Németország feladja a nukleáris energiával szembeni ellenállását Franciaországgal való közeledés jegyében
Németország hosszú idő után feladta a nukleáris energiával szembeni ellenállását, ami jelentős lépést jelenthet az EU energiapolitikai vitáinak rendezésében, különösen Franciaországgal szemben. Ez a változás eltávolíthatja a nukleáris energiával szembeni előítéleteket az uniós jogszabályokból, és elősegítheti a közös európai energiapolitika kialakítását[2].
Trump adminisztráció tervezett rendeletei a nukleáris erőművek építésének gyorsítására
Az Egyesült Államokban a Trump-adminisztráció több elnöki rendelet-tervezetet készít elő, amelyek célja a nukleáris erőművek építésének gyorsítása. A tervek szerint a jelenlegi mintegy 100 GW nukleáris kapacitást 2050-re 400 GW-ra növelnék, az engedélyezési folyamatok egyszerűsítésével, a hadsereg szerepének növelésével és a nukleáris üzemanyag-ellátás megerősítésével[3][9].
Tajvan hivatalosan is nukleárismentes lett
- május 17-én Tajvan utolsó kereskedelmi reaktorát is leállították, ezzel az ország elérte a "nukleárismentes haza" célját. Az energiamixben a nukleáris energia aránya 17%-ról 3%-ra csökkent, miközben a megújuló energia tízszeresére nőtt. Bár a parlamentben vita folyik a Maanshan atomerőmű élettartam-hosszabbításáról, jelenleg Tajvan teljesen leállította a nukleáris energiatermelést[1][6].
Kazatomprom hitelmegállapodást kötött egy új kénsavgyár finanszírozására
Kazahsztán állami atomipari vállalata, a Kazatomprom hitelmegállapodást kötött egy évi 800 000 tonna kapacitású kénsavgyár építésére. A kénsavat az uránkitermeléshez használják, és a gyár 2027 első negyedévében készülhet el. A projekt célja a régió gazdasági fejlődésének támogatása és az uránipar ellátásbiztonságának javítása[4].
Az IAEA segíti Kazahsztánt az első atomerőmű biztonságos helyszínének kiválasztásában
Az IAEA (Nemzetközi Atomenergia-ügynökség) szakértői csapata ötnapos szemináriumot tart Kazahsztánban, hogy segítsen kiválasztani az ország első atomerőművének legbiztonságosabb helyszínét. A folyamatban több helyszín is szóba került, jelenleg a Zhambyl körzet az elsődleges jelölt. A projektben négy lehetséges technológiai partner vesz részt: CNNC (Kína), Roszatom (Oroszország), KHNP (Dél-Korea) és EDF (Franciaország)[8].
India új nukleáris helyszínt hagyott jóvá
Az indiai nukleáris hatóság engedélyezte a Mahi Banswara Rajasthan Atomic Power Project négy blokkjának elhelyezését Rádzsasztán államban. Ez újabb lépés India ambiciózus nukleáris bővítési terveiben[5].
Globális nukleáris ipari konferencia Varsóban
- május 20-21-én Varsóban rendezik meg az első World Nuclear Supply Chain Conference-t, amely célja a globális nukleáris ellátási lánc megerősítése és a szektor 2 billió dolláros beruházási lehetőségének kiaknázása a következő 15 évben. A konferencián iparági vezetők, döntéshozók és szakértők vesznek részt[7].

2025-01-19 17:48:02Einleitung\ \ Schwierige Dinge einfach zu erklären ist der Anspruch von ELI5 (explain me like I'm 5). Das ist in unserer hoch technisierten Welt dringend erforderlich, denn nur mit dem Verständnis der Technologien können wir sie richtig einsetzen und weiter entwickeln.\ Ich starte meine Serie mit Nostr, einem relativ neuen Internet-Protokoll. Was zum Teufel ist ein Internet-Protokoll? Formal beschrieben sind es internationale Standards, die dafür sorgen, dass das Internet seit über 30 Jahren ziemlich gut funktioniert. Es ist die Sprache, in der sich die Rechner miteinander unterhalten und die auch Sie täglich nutzen, vermutlich ohne es bewusst wahrzunehmen. http(s) transportiert ihre Anfrage an einen Server (z.B. Amazon), und html sorgt dafür, dass aus den gelieferten Daten eine schöne Seite auf ihrem Bildschirm entsteht. Eine Mail wird mit smtp an den Mailserver gesendet und mit imap von ihm abgerufen, und da alle den Standard verwenden, funktioniert das mit jeder App auf jedem Betriebssystem und mit jedem Mail-Provider. Und mit einer Mail-Adresse wie roland@pareto.space können sie sogar jederzeit umziehen, egal wohin. Cool, das ist state of the art! Aber warum funktioniert das z.B. bei Chat nicht, gibt es da kein Protokoll? Doch, es heißt IRC (Internet Relay Chat → merken sie sich den Namen), aber es wird so gut wie nicht verwendet. Die Gründe dafür sind nicht technischer Natur, vielmehr wurden mit Apps wie Facebook, Twitter, WhatsApp, Telegram, Instagram, TikTok u.a. bewusst Inkompatibilitäten und Nutzerabhängigkeiten geschaffen um Profite zu maximieren.
Warum Nostr?
Da das Standard-Protokoll nicht genutzt wird, hat jede App ihr eigenes, und wir brauchen eine handvoll Apps um uns mit allen Bekannten auszutauschen. Eine Mobilfunknummer ist Voraussetzung für jedes Konto, damit können die App-Hersteller die Nutzer umfassend tracken und mit dem Verkauf der Informationen bis zu 30 USD je Konto und Monat verdienen. Der Nutzer ist nicht mehr Kunde, er ist das Produkt! Der Werbe-SPAM ist noch das kleinste Problem bei diesem Geschäftsmodell. Server mit Millionen von Nutzerdaten sind ein “honey pot”, dementsprechend oft werden sie gehackt und die Zugangsdaten verkauft. 2024 wurde auch der Twitter-Account vom damaligen Präsidenten Joe Biden gehackt, niemand wusste mehr wer die Nachrichten verfasst hat (vorher auch nicht), d.h. die Authentizität der Inhalte ist bei keinem dieser Anbieter gewährleistet. Im selben Jahr wurde der Telegram-Gründer in Frankreich in Beugehaft genommen, weil er sich geweigert hatte Hintertüren in seine Software einzubauen. Nun kann zum Schutz "unserer Demokratie” praktisch jeder mitlesen, was sie mit wem an Informationen austauschen, z.B. darüber welches Shampoo bestimmte Politiker verwenden.
Und wer tatsächlich glaubt er könne Meinungsfreiheit auf sozialen Medien praktizieren, findet sich schnell in der Situation von Donald Trump wieder (seinerzeit amtierender Präsident), dem sein Twitter-Konto 2021 abgeschaltet wurde (Cancel-Culture). Die Nutzerdaten, also ihr Profil, ihre Kontakte, Dokumente, Bilder, Videos und Audiofiles - gehören ihnen ohnehin nicht mehr sondern sind Eigentum des Plattform-Betreibers; lesen sie sich mal die AGB's durch. Aber nein, keine gute Idee, das sind hunderte Seiten und sie werden permanent geändert. Alle nutzen also Apps, deren Technik sie nicht verstehen, deren Regeln sie nicht kennen, wo sie keine Rechte haben und die ihnen die Resultate ihres Handelns stehlen. Was würde wohl der Fünfjährige sagen, wenn ihm seine ältere Schwester anbieten würde, alle seine Spielzeuge zu “verwalten” und dann auszuhändigen wenn er brav ist? “Du spinnst wohl”, und damit beweist der Knirps mehr Vernunft als die Mehrzahl der Erwachsenen. \ \ Resümee: keine Standards, keine Daten, keine Rechte = keine Zukunft!
\ Wie funktioniert Nostr?
Die Entwickler von Nostr haben erkannt dass sich das Server-Client-Konzept in ein Master-Slave-Konzept verwandelt hatte. Der Master ist ein Synonym für Zentralisierung und wird zum “single point of failure”, der zwangsläufig Systeme dysfunktional macht. In einem verteilten Peer2Peer-System gibt es keine Master mehr sondern nur gleichberechtigte Knoten (Relays), auf denen die Informationen gespeichert werden. Indem man Informationen auf mehreren Relays redundant speichert, ist das System in jeglicher Hinsicht resilienter. Nicht nur die Natur verwendet dieses Prinzip seit Jahrmillionen erfolgreich, auch das Internet wurde so konzipiert (das ARPAnet wurde vom US-Militär für den Einsatz in Kriegsfällen unter massiven Störungen entwickelt). Alle Nostr-Daten liegen auf Relays und der Nutzer kann wählen zwischen öffentlichen (zumeist kostenlosen) und privaten Relays, z.B. für geschlossene Gruppen oder zum Zwecke von Daten-Archivierung. Da Dokumente auf mehreren Relays gespeichert sind, werden statt URL's (Locator) eindeutige Dokumentnamen (URI's = Identifier) verwendet, broken Links sind damit Vergangenheit und Löschungen / Verluste ebenfalls.\ \ Jedes Dokument (Event genannt) wird vom Besitzer signiert, es ist damit authentisch und fälschungssicher und kann nur vom Ersteller gelöscht werden. Dafür wird ein Schlüsselpaar verwendet bestehend aus privatem (nsec) und öffentlichem Schlüssel (npub) wie aus der Mailverschlüsselung (PGP) bekannt. Das repräsentiert eine Nostr-Identität, die um Bild, Namen, Bio und eine lesbare Nostr-Adresse ergänzt werden kann (z.B. roland@pareto.space ), mehr braucht es nicht um alle Ressourcen des Nostr-Ökosystems zu nutzen. Und das besteht inzwischen aus über hundert Apps mit unterschiedlichen Fokussierungen, z.B. für persönliche verschlüsselte Nachrichten (DM → OxChat), Kurznachrichten (Damus, Primal), Blogbeiträge (Pareto), Meetups (Joinstr), Gruppen (Groups), Bilder (Olas), Videos (Amethyst), Audio-Chat (Nostr Nests), Audio-Streams (Tunestr), Video-Streams (Zap.Stream), Marktplätze (Shopstr) u.v.a.m. Die Anmeldung erfolgt mit einem Klick (single sign on) und den Apps stehen ALLE Nutzerdaten zur Verfügung (Profil, Daten, Kontakte, Social Graph → Follower, Bookmarks, Comments, etc.), im Gegensatz zu den fragmentierten Datensilos der Gegenwart.\ \ Resümee: ein offener Standard, alle Daten, alle Rechte = große Zukunft!
\ Warum ist Nostr die Zukunft des Internet?
“Baue Dein Haus nicht auf einem fremden Grundstück” gilt auch im Internet - für alle App-Entwickler, Künstler, Journalisten und Nutzer, denn auch ihre Daten sind werthaltig. Nostr garantiert das Eigentum an den Daten, und überwindet ihre Fragmentierung. Weder die Nutzung noch die kreativen Freiheiten werden durch maßlose Lizenz- und Nutzungsbedingungen eingeschränkt. Aus passiven Nutzern werden durch Interaktion aktive Teilnehmer, Co-Creatoren in einer Sharing-Ökonomie (Value4Value). OpenSource schafft endlich wieder Vertrauen in die Software und ihre Anbieter. Offene Standards ermöglichen den Entwicklern mehr Kooperation und schnellere Entwicklung, für die Anwender garantieren sie Wahlfreiheit. Womit wir letztmalig zu unserem Fünfjährigen zurückkehren. Kinder lieben Lego über alles, am meisten die Maxi-Box “Classic”, weil sie damit ihre Phantasie im Kombinieren voll ausleben können. Erwachsene schenken ihnen dann die viel zu teuren Themenpakete, mit denen man nur eine Lösung nach Anleitung bauen kann. “Was stimmt nur mit meinen Eltern nicht, wann sind die denn falsch abgebogen?" fragt sich der Nachwuchs zu Recht. Das Image lässt sich aber wieder aufpolieren, wenn sie ihren Kindern Nostr zeigen, denn die Vorteile verstehen sogar Fünfjährige.
\ Das neue Internet ist dezentral. Das neue Internet ist selbstbestimmt. Nostr ist das neue Internet.

2025-05-15 17:40:26It's been in the news recently that Mike Waltz was not using Signal but an app called TeleMessage, which is marketed as a tool to archive Signal chat conversations. This event presents a great opportunity for learning. After years of following security and privacy tech, one of the many lessons I've learned is that humans are almost always the weak link in security. Foolish decisions are usually at the root of most breaches and attacks. This was the case with the Trump admin. I am of the opinion that it is foolish to use devices like the iPhone or any phone OS for secure communication. Not because the devices are not secure—they can be very secure. It's that humans can break this security very easily with careless behavior, as we see in this case.
While Signal encrypts messages in transit[^1] and at rest on your mobile devices, it is important to remember that any encrypted messenger app, whether it's Signal, WhatsApp, Apple Messages, or SimpleX, must decrypt the messages for you to read them. There really isn't a way around this. So, with this in mind, it's obvious that trust is involved when using any of these apps. First, you are trusting the person you are conversing with. This might seem trivial, but it seems to be lost on many people. When you send a message to another party, you have no idea what they are doing with it. Apps like Signal try to mitigate this by offering disappearing messages. Some apps don't allow screenshots of the application. But make no mistake, if your message is readable by a human, they can capture it. Even if they just snap a picture of it from another device. If that were the only thing to consider, we could end this now, but it's not.
You are also trusting the phone/device OS. While I think it is unlikely that Apple and Google are capturing the screens on devices and apps like Signal, we cannot have 100% certainty of this. At least I do not. But it's worse than this. There are attack toolkits like Pegasus which can be covertly installed on phones like the iPhone and most Android devices. It is almost certain that Pegasus or something like it could capture and expose your private messages when you read them. This is because they basically gain low-level access to the device without your knowledge. And because humans can't mentally unencrypt messages, Signal must decrypt the message for you to read it. When it does, the malicious app can capture it and send it off to the attacker. FWIW, this is possibly what happened to Tucker Carlson when he claimed that Signal "leaked" his communication about traveling to Russia to interview Putin. Though I suspect it is more likely a mole in either his operation or the Russians. The least likely scenario is that Signal was actually compromised.
So no matter how secure your messaging app may be, if your phone OS is compromised, it's game over. This wasn't the case here as Waltz foolishly was using a clone of the Signal app called TM SGNL to log Signal chats and send them to the TeleMessage servers. It appears that this was done in the clear and that the logs were even emailed to mail servers. You can read more about this in a post I made earlier today. So, as you can see, he wasn't actually using Signal at all. Signal was not the issue.
So what should you do now that you are armed with this knowledge? Well, first of all, you should take everything I write with a grain of salt. Do your own research and do not do anything you don't feel comfortable doing. Don't trust, verify. With that caveat, the likelihood of Signal being compromised in my opinion is low. The likelihood that Apple or Google is logging your Signal chats is also low. I think they could if they desired. The likelihood of your being targeted with something like Pegasus is also low but not impossible. I don't know you or your threat model. It's something to think about. But here is something everyone should consider.
The most important thing to consider is that you are always trusting the person you communicate with. This is not only true for digital communication but also in-person communication. Of course, SMS is not secure, but I do use it for things that I have no concern about being recorded. But I do prefer to use encryption when I can. A side note, we seem to be heading toward a secure-by-default standard in the future with SMS[^2], which is good to hear. I use Signal with any friends that are willing to use it, but I do not trust them all equally. For one thing, most of us do not trust everyone equally for anything. Trust is earned and built over time. But even for people I trust, I may not trust their technical skills or security practices. This has to be a consideration when you use Signal. Signal cannot protect you against a malicious recipient. This person could be building a log of your conversations. They might even be hacked and unaware. They could be using an insecure client, as was the case with the Trump admin.
So be aware. The best policy is to be very careful with anything you put in a digital device. The best way to keep a secret is to not share it. There are many thoughts and communications that I would never use a phone or computer to communicate. I think people would be wise to do the same.

@ 0b118e40:4edc09cb
2025-05-15 15:40:21My week started off with a lovely message from a friend : “I often think about you. Especially during times when it requires me to be more resilient and have faith in myself. I always carry your note in the book you gave me, “what the dog saw” And it always gives me courage and I send a little prayer your way”.
This friend of mine was dealing with the undercurrent of discrimination in my alma mater when we first met, and I helped out. It's something anybody would have done, but surprisingly, nobody else showed up. We’ve stayed in touch over the years, and my friend went on to help a lot of other people along the way.
I don’t remember what I wrote in that note. It’s something I tend to do (write notes, give books, write notes in books). But the message boomeranged back to me at a time when I needed to hold the line. To keep the faith.
Most of us don’t talk about our struggles. And sometimes the smallest act, which could just be a kind word or a reminder of the person you are, can carry farther than we imagine.
On the act of giving
There’s a book called Give and Take by Adam Grant. I picked it up hoping to learn how to take, because it’s always been easier to give and harder to accept help. But what I learned was something else entirely.
Grant studied over 30,000 people across different companies and grouped them into three types: * Givers * Matchers * Takers
Based on his studies, givers often finish last... They struggle the most. They burn out. They get overlooked. They’re too trusting.
But oddly, they also rise to the very top.
Matchers are the scorekeepers, the “I’ll help you if you help me” kind. They make up most of the population. The fascinating thing about tit-for-tat is that if someone’s kind, they reciprocate. But if someone acts like a jerk, they return the energy, and over time, it becomes a pool of spoiled milk. Matchers are a lukewarm, forgettable kind of network.
Takers are the ones chasing attention, always aligning themselves with whoever looks powerful. They tend to float toward status and soak up what they can. But they often portray themselves as kind and giving.
One example Grant shared was Enron's Kenneth Lay, who was at the center of one of the biggest corporate scandals in U.S. history. He hung around wherever he’d get seen or validated. He funded both Bush and Clinton, hedging his bets on who might win by securing proximity. Sadly, when Enron crumbled, he died of a heart attack before his prison sentencing.
Most people steer clear from takers because they are just exhausting. And takers often collapse under the weight of their own games.
But takers aren’t the lowest performers. That spot belongs to a certain kind of giver—the self-neglecting kind. The ones with no boundaries, no clarity, and no self-awareness. They give in to avoid conflict, to feel worthy, or because they don’t know how to say no. And when life breaks them, they point fingers.
Then there’s the other kind of giver. The ones who build trust and build people up without asking for a receipt.
These givers: 1. Give without expectation, from a place of purpose 2. Build and uplift others without seeking credit 3. Set boundaries and walk away when giving turns into draining
This group of givers rarely talk much about what they do for others. But when you hear about it or see it, it stays with you. It makes you want to show up a little better.
Why open source environments feels like home
The more I thought about it, the more I saw how deeply open source reflects that kind of giving that ends up right at the top.
In open source, you don’t last if it’s just about ego. You can’t fake it. There are no titles, no awards. You either show up to build and help, or you don’t.
People who give without needing to be seen are the ones the community leans on. You can tell when someone’s pretending to care. It’s in their tone, their urgency and their sense of transaction. The genuine ones don’t need to brand themselves as generous. They just are.
Open source works because giving is the default setting. The work speaks volumes and generosity compounds. The system filters for people who show up with purpose and stay consistent.
It’s also why the ones who whine, posture, or manipulate rarely last. They might call themselves givers, but they’re not fooling anyone who’s actually doing the work.
Adam Grant found that for giver cultures to thrive, takers have to be removed. They need to be pruned. Because takers poison the well. They drain givers, shift the culture from contribution to calculation, and unravel the trust that holds open systems together.
When hope boomerangs
That note is something I don’t remember writing. But it found its way back to me, and it was a good reminder to take my own advice and keep the faith.
And maybe that’s the point.
You do a small thing. And years later, it circles back when it matters most. Not because you expected it. But because you mattered.
According to Grant, givers do best when they combine generosity with grit and strategy. They create networks built on goodwill, which eventually open doors others don’t even know exist.
So if you’re wondering where I’m going with this, do something genuinely kind for someone today. Even if it’s as simple as sending a kind note. Not for you to be seen or heard. And not for you to keep scores.
But, just because.

2025-05-15 15:31:45Capitalism is the most effective system for scaling innovation. The pursuit of profit is an incredibly powerful human incentive. Most major improvements to human society and quality of life have resulted from this base incentive. Market competition often results in the best outcomes for all.
That said, some projects can never be monetized. They are open in nature and a business model would centralize control. Open protocols like bitcoin and nostr are not owned by anyone and if they were it would destroy the key value propositions they provide. No single entity can or should control their use. Anyone can build on them without permission.
As a result, open protocols must depend on donation based grant funding from the people and organizations that rely on them. This model works but it is slow and uncertain, a grind where sustainability is never fully reached but rather constantly sought. As someone who has been incredibly active in the open source grant funding space, I do not think people truly appreciate how difficult it is to raise charitable money and deploy it efficiently.
Projects that can be monetized should be. Profitability is a super power. When a business can generate revenue, it taps into a self sustaining cycle. Profit fuels growth and development while providing projects independence and agency. This flywheel effect is why companies like Google, Amazon, and Apple have scaled to global dominance. The profit incentive aligns human effort with efficiency. Businesses must innovate, cut waste, and deliver value to survive.
Contrast this with non monetized projects. Without profit, they lean on external support, which can dry up or shift with donor priorities. A profit driven model, on the other hand, is inherently leaner and more adaptable. It is not charity but survival. When survival is tied to delivering what people want, scale follows naturally.
The real magic happens when profitable, sustainable businesses are built on top of open protocols and software. Consider the many startups building on open source software stacks, such as Start9, Mempool, and Primal, offering premium services on top of the open source software they build out and maintain. Think of companies like Block or Strike, which leverage bitcoin’s open protocol to offer their services on top. These businesses amplify the open software and protocols they build on, driving adoption and improvement at a pace donations alone could never match.
When you combine open software and protocols with profit driven business the result are lean, sustainable companies that grow faster and serve more people than either could alone. Bitcoin’s network, for instance, benefits from businesses that profit off its existence, while nostr will expand as developers monetize apps built on the protocol.
Capitalism scales best because competition results in efficiency. Donation funded protocols and software lay the groundwork, while market driven businesses build on top. The profit incentive acts as a filter, ensuring resources flow to what works, while open systems keep the playing field accessible, empowering users and builders. Together, they create a flywheel of innovation, growth, and global benefit.

Documentation and Wikis with Spaces and Format Declaration
draft
optional
Summary
This NIP introduces a system for collaborative documentation and wikis on Nostr. It improves upon earlier efforts by adding namespace-like Spaces, explicit content format declaration, and clearer separation of article types, including redirects and merge requests.
Motivation
Previous approaches to wiki-style collaborative content on Nostr had two key limitations:
- Format instability – No declared format per event led to breaking changes (e.g. a shift from Markdown to Asciidoc).
- Lack of namespace separation – All articles existed in a global space, causing confusion and collision between unrelated projects.
This NIP addresses both by introducing:
- Spaces – individually defined wikis or documentation sets.
- Explicit per-article format declaration.
- Dedicated event kinds for articles, redirects, merge requests, and space metadata.
Specification
kind: 31055
– Space DefinitionDefines a project namespace for articles.
Tags: -
["name", "<space title>"]
-["slug", "<short identifier>"]
-["description", "<optional description>"]
-["language", "<ISO language code>"]
-["license", "<license text or SPDX ID>"]
Content: (optional) full description or README for the space.
kind: 31056
– ArticleAn article in a specific format belonging to a defined space.
Tags: -
["space", "<slug>"]
-["title", "<article title>"]
-["format", "markdown" | "asciidoc" | "mediawiki" | "html"]
-["format-version", "<format version>"]
(optional) -["prev", "<event-id>"]
(optional) -["summary", "<short change summary>"]
(optional)Content: full body of the article in the declared format.
kind: 31057
– RedirectRedirects from one article title to another within the same space.
Tags: -
["space", "<slug>"]
-["from", "<old title>"]
-["to", "<new title>"]
Content: empty.
kind: 31058
– Merge RequestProposes a revision to an article without directly altering the original.
Tags: -
["space", "<slug>"]
-["title", "<article title>"]
-["base", "<event-id>"]
-["format", "<format>"]
-["comment", "<short summary>"]
(optional)Content: proposed article content.
Format Guidelines
Currently allowed formats: -
markdown
-asciidoc
-mediawiki
-html
Clients MUST ignore formats they do not support. Clients MAY apply stricter formatting rules.
Client Behavior
Clients: - MUST render only supported formats. - MUST treat
space
as a case-sensitive namespace. - SHOULD allow filtering, browsing and searching within Spaces. - SHOULD support revision tracking viaprev
. - MAY support diff/merge tooling forkind: 31058
.
Examples

Acknowledgements
This proposal builds on earlier ideas for decentralized wikis and documentation within Nostr, while solving common issues related to format instability and lack of project separation.

2025-01-14 01:31:12Bitcoin is more than money, more than an asset, and more than a store of value. Bitcoin is a Prime Mover, an enabler and it ignites imaginations. It certainly fueled an idea in my mind. The idea integrates sensors, computational prowess, actuated machinery, power conversion, and electronic communications to form an autonomous, machined creature roaming forests and harvesting the most widespread and least energy-dense fuel source available. I call it the Forest Walker and it eats wood, and mines Bitcoin.
I know what you're thinking. Why not just put Bitcoin mining rigs where they belong: in a hosted facility sporting electricity from energy-dense fuels like natural gas, climate-controlled with excellent data piping in and out? Why go to all the trouble building a robot that digests wood creating flammable gasses fueling an engine to run a generator powering Bitcoin miners? It's all about synergy.
Bitcoin mining enables the realization of multiple, seemingly unrelated, yet useful activities. Activities considered un-profitable if not for Bitcoin as the Prime Mover. This is much more than simply mining the greatest asset ever conceived by humankind. It’s about the power of synergy, which Bitcoin plays only one of many roles. The synergy created by this system can stabilize forests' fire ecology while generating multiple income streams. That’s the realistic goal here and requires a brief history of American Forest management before continuing.
Smokey The Bear
In 1944, the Smokey Bear Wildfire Prevention Campaign began in the United States. “Only YOU can prevent forest fires” remains the refrain of the Ad Council’s longest running campaign. The Ad Council is a U.S. non-profit set up by the American Association of Advertising Agencies and the Association of National Advertisers in 1942. It would seem that the U.S. Department of the Interior was concerned about pesky forest fires and wanted them to stop. So, alongside a national policy of extreme fire suppression they enlisted the entire U.S. population to get onboard via the Ad Council and it worked. Forest fires were almost obliterated and everyone was happy, right? Wrong.
Smokey is a fantastically successful bear so forest fires became so few for so long that the fuel load - dead wood - in forests has become very heavy. So heavy that when a fire happens (and they always happen) it destroys everything in its path because the more fuel there is the hotter that fire becomes. Trees, bushes, shrubs, and all other plant life cannot escape destruction (not to mention homes and businesses). The soil microbiology doesn’t escape either as it is burned away even in deeper soils. To add insult to injury, hydrophobic waxy residues condense on the soil surface, forcing water to travel over the ground rather than through it eroding forest soils. Good job, Smokey. Well done, Sir!
Most terrestrial ecologies are “fire ecologies”. Fire is a part of these systems’ fuel load and pest management. Before we pretended to “manage” millions of acres of forest, fires raged over the world, rarely damaging forests. The fuel load was always too light to generate fires hot enough to moonscape mountainsides. Fires simply burned off the minor amounts of fuel accumulated since the fire before. The lighter heat, smoke, and other combustion gasses suppressed pests, keeping them in check and the smoke condensed into a plant growth accelerant called wood vinegar, not a waxy cap on the soil. These fires also cleared out weak undergrowth, cycled minerals, and thinned the forest canopy, allowing sunlight to penetrate to the forest floor. Without a fire’s heat, many pine tree species can’t sow their seed. The heat is required to open the cones (the seed bearing structure) of Spruce, Cypress, Sequoia, Jack Pine, Lodgepole Pine and many more. Without fire forests can’t have babies. The idea was to protect the forests, and it isn't working.
So, in a world of fire, what does an ally look like and what does it do?
Meet The Forest Walker
For the Forest Walker to work as a mobile, autonomous unit, a solid platform that can carry several hundred pounds is required. It so happens this chassis already exists but shelved.
Introducing the Legged Squad Support System (LS3). A joint project between Boston Dynamics, DARPA, and the United States Marine Corps, the quadrupedal robot is the size of a cow, can carry 400 pounds (180 kg) of equipment, negotiate challenging terrain, and operate for 24 hours before needing to refuel. Yes, it had an engine. Abandoned in 2015, the thing was too noisy for military deployment and maintenance "under fire" is never a high-quality idea. However, we can rebuild it to act as a platform for the Forest Walker; albeit with serious alterations. It would need to be bigger, probably. Carry more weight? Definitely. Maybe replace structural metal with carbon fiber and redesign much as 3D printable parts for more effective maintenance.
The original system has a top operational speed of 8 miles per hour. For our purposes, it only needs to move about as fast as a grazing ruminant. Without the hammering vibrations of galloping into battle, shocks of exploding mortars, and drunken soldiers playing "Wrangler of Steel Machines", time between failures should be much longer and the overall energy consumption much lower. The LS3 is a solid platform to build upon. Now it just needs to be pulled out of the mothballs, and completely refitted with outboard equipment.
The Small Branch Chipper
When I say “Forest fuel load” I mean the dead, carbon containing litter on the forest floor. Duff (leaves), fine-woody debris (small branches), and coarse woody debris (logs) are the fuel that feeds forest fires. Walk through any forest in the United States today and you will see quite a lot of these materials. Too much, as I have described. Some of these fuel loads can be 8 tons per acre in pine and hardwood forests and up to 16 tons per acre at active logging sites. That’s some big wood and the more that collects, the more combustible danger to the forest it represents. It also provides a technically unlimited fuel supply for the Forest Walker system.
The problem is that this detritus has to be chewed into pieces that are easily ingestible by the system for the gasification process (we’ll get to that step in a minute). What we need is a wood chipper attached to the chassis (the LS3); its “mouth”.
A small wood chipper handling material up to 2.5 - 3.0 inches (6.3 - 7.6 cm) in diameter would eliminate a substantial amount of fuel. There is no reason for Forest Walker to remove fallen trees. It wouldn’t have to in order to make a real difference. It need only identify appropriately sized branches and grab them. Once loaded into the chipper’s intake hopper for further processing, the beast can immediately look for more “food”. This is essentially kindling that would help ignite larger logs. If it’s all consumed by Forest Walker, then it’s not present to promote an aggravated conflagration.
I have glossed over an obvious question: How does Forest Walker see and identify branches and such? LiDaR (Light Detection and Ranging) attached to Forest Walker images the local area and feed those data to onboard computers for processing. Maybe AI plays a role. Maybe simple machine learning can do the trick. One thing is for certain: being able to identify a stick and cause robotic appendages to pick it up is not impossible.
Great! We now have a quadrupedal robot autonomously identifying and “eating” dead branches and other light, combustible materials. Whilst strolling through the forest, depleting future fires of combustibles, Forest Walker has already performed a major function of this system: making the forest safer. It's time to convert this low-density fuel into a high-density fuel Forest Walker can leverage. Enter the gasification process.
The Gassifier
The gasifier is the heart of the entire system; it’s where low-density fuel becomes the high-density fuel that powers the entire system. Biochar and wood vinegar are process wastes and I’ll discuss why both are powerful soil amendments in a moment, but first, what’s gasification?
Reacting shredded carbonaceous material at high temperatures in a low or no oxygen environment converts the biomass into biochar, wood vinegar, heat, and Synthesis Gas (Syngas). Syngas consists primarily of hydrogen, carbon monoxide, and methane. All of which are extremely useful fuels in a gaseous state. Part of this gas is used to heat the input biomass and keep the reaction temperature constant while the internal combustion engine that drives the generator to produce electrical power consumes the rest.
Critically, this gasification process is “continuous feed”. Forest Walker must intake biomass from the chipper, process it to fuel, and dump the waste (CO2, heat, biochar, and wood vinegar) continuously. It cannot stop. Everything about this system depends upon this continual grazing, digestion, and excretion of wastes just as a ruminal does. And, like a ruminant, all waste products enhance the local environment.
When I first heard of gasification, I didn’t believe that it was real. Running an electric generator from burning wood seemed more akin to “conspiracy fantasy” than science. Not only is gasification real, it’s ancient technology. A man named Dean Clayton first started experiments on gasification in 1699 and in 1901 gasification was used to power a vehicle. By the end of World War II, there were 500,000 Syngas powered vehicles in Germany alone because of fossil fuel rationing during the war. The global gasification market was $480 billion in 2022 and projected to be as much as $700 billion by 2030 (Vantage Market Research). Gasification technology is the best choice to power the Forest Walker because it’s self-contained and we want its waste products.
Biochar: The Waste
Biochar (AKA agricultural charcoal) is fairly simple: it’s almost pure, solid carbon that resembles charcoal. Its porous nature packs large surface areas into small, 3 dimensional nuggets. Devoid of most other chemistry, like hydrocarbons (methane) and ash (minerals), biochar is extremely lightweight. Do not confuse it with the charcoal you buy for your grill. Biochar doesn’t make good grilling charcoal because it would burn too rapidly as it does not contain the multitude of flammable components that charcoal does. Biochar has several other good use cases. Water filtration, water retention, nutrient retention, providing habitat for microscopic soil organisms, and carbon sequestration are the main ones that we are concerned with here.
Carbon has an amazing ability to adsorb (substances stick to and accumulate on the surface of an object) manifold chemistries. Water, nutrients, and pollutants tightly bind to carbon in this format. So, biochar makes a respectable filter and acts as a “battery” of water and nutrients in soils. Biochar adsorbs and holds on to seven times its weight in water. Soil containing biochar is more drought resilient than soil without it. Adsorbed nutrients, tightly sequestered alongside water, get released only as plants need them. Plants must excrete protons (H+) from their roots to disgorge water or positively charged nutrients from the biochar's surface; it's an active process.
Biochar’s surface area (where adsorption happens) can be 500 square meters per gram or more. That is 10% larger than an official NBA basketball court for every gram of biochar. Biochar’s abundant surface area builds protective habitats for soil microbes like fungi and bacteria and many are critical for the health and productivity of the soil itself.
The “carbon sequestration” component of biochar comes into play where “carbon credits” are concerned. There is a financial market for carbon. Not leveraging that market for revenue is foolish. I am climate agnostic. All I care about is that once solid carbon is inside the soil, it will stay there for thousands of years, imparting drought resiliency, fertility collection, nutrient buffering, and release for that time span. I simply want as much solid carbon in the soil because of the undeniably positive effects it has, regardless of any climactic considerations.
Wood Vinegar: More Waste
Another by-product of the gasification process is wood vinegar (Pyroligneous acid). If you have ever seen Liquid Smoke in the grocery store, then you have seen wood vinegar. Principally composed of acetic acid, acetone, and methanol wood vinegar also contains ~200 other organic compounds. It would seem intuitive that condensed, liquefied wood smoke would at least be bad for the health of all living things if not downright carcinogenic. The counter intuition wins the day, however. Wood vinegar has been used by humans for a very long time to promote digestion, bowel, and liver health; combat diarrhea and vomiting; calm peptic ulcers and regulate cholesterol levels; and a host of other benefits.
For centuries humans have annually burned off hundreds of thousands of square miles of pasture, grassland, forest, and every other conceivable terrestrial ecosystem. Why is this done? After every burn, one thing becomes obvious: the almost supernatural growth these ecosystems exhibit after the burn. How? Wood vinegar is a component of this growth. Even in open burns, smoke condenses and infiltrates the soil. That is when wood vinegar shows its quality.
This stuff beefs up not only general plant growth but seed germination as well and possesses many other qualities that are beneficial to plants. It’s a pesticide, fungicide, promotes beneficial soil microorganisms, enhances nutrient uptake, and imparts disease resistance. I am barely touching a long list of attributes here, but you want wood vinegar in your soil (alongside biochar because it adsorbs wood vinegar as well).
The Internal Combustion Engine
Conversion of grazed forage to chemical, then mechanical, and then electrical energy completes the cycle. The ICE (Internal Combustion Engine) converts the gaseous fuel output from the gasifier to mechanical energy, heat, water vapor, and CO2. It’s the mechanical energy of a rotating drive shaft that we want. That rotation drives the electric generator, which is the heartbeat we need to bring this monster to life. Luckily for us, combined internal combustion engine and generator packages are ubiquitous, delivering a defined energy output given a constant fuel input. It’s the simplest part of the system.
The obvious question here is whether the amount of syngas provided by the gasification process will provide enough energy to generate enough electrons to run the entire system or not. While I have no doubt the energy produced will run Forest Walker's main systems the question is really about the electrons left over. Will it be enough to run the Bitcoin mining aspect of the system? Everything is a budget.
CO2 Production For Growth
Plants are lollipops. No matter if it’s a tree or a bush or a shrubbery, the entire thing is mostly sugar in various formats but mostly long chain carbohydrates like lignin and cellulose. Plants need three things to make sugar: CO2, H2O and light. In a forest, where tree densities can be quite high, CO2 availability becomes a limiting growth factor. It’d be in the forest interests to have more available CO2 providing for various sugar formation providing the organism with food and structure.
An odd thing about tree leaves, the openings that allow gasses like the ever searched for CO2 are on the bottom of the leaf (these are called stomata). Not many stomata are topside. This suggests that trees and bushes have evolved to find gasses like CO2 from below, not above and this further suggests CO2 might be in higher concentrations nearer the soil.
The soil life (bacterial, fungi etc.) is constantly producing enormous amounts of CO2 and it would stay in the soil forever (eventually killing the very soil life that produces it) if not for tidal forces. Water is everywhere and whether in pools, lakes, oceans or distributed in “moist” soils water moves towards to the moon. The water in the soil and also in the water tables below the soil rise toward the surface every day. When the water rises, it expels the accumulated gasses in the soil into the atmosphere and it’s mostly CO2. It’s a good bet on how leaves developed high populations of stomata on the underside of leaves. As the water relaxes (the tide goes out) it sucks oxygenated air back into the soil to continue the functions of soil life respiration. The soil “breathes” albeit slowly.
The gasses produced by the Forest Walker’s internal combustion engine consist primarily of CO2 and H2O. Combusting sugars produce the same gasses that are needed to construct the sugars because the universe is funny like that. The Forest Walker is constantly laying down these critical construction elements right where the trees need them: close to the ground to be gobbled up by the trees.
The Branch Drones
During the last ice age, giant mammals populated North America - forests and otherwise. Mastodons, woolly mammoths, rhinos, short-faced bears, steppe bison, caribou, musk ox, giant beavers, camels, gigantic ground-dwelling sloths, glyptodons, and dire wolves were everywhere. Many were ten to fifteen feet tall. As they crashed through forests, they would effectively cleave off dead side-branches of trees, halting the spread of a ground-based fire migrating into the tree crown ("laddering") which is a death knell for a forest.
These animals are all extinct now and forests no longer have any manner of pruning services. But, if we build drones fitted with cutting implements like saws and loppers, optical cameras and AI trained to discern dead branches from living ones, these drones could effectively take over pruning services by identifying, cutting, and dropping to the forest floor, dead branches. The dropped branches simply get collected by the Forest Walker as part of its continual mission.
The drones dock on the back of the Forest Walker to recharge their batteries when low. The whole scene would look like a grazing cow with some flies bothering it. This activity breaks the link between a relatively cool ground based fire and the tree crowns and is a vital element in forest fire control.
The Bitcoin Miner
Mining is one of four monetary incentive models, making this system a possibility for development. The other three are US Dept. of the Interior, township, county, and electrical utility company easement contracts for fuel load management, global carbon credits trading, and data set sales. All the above depends on obvious questions getting answered. I will list some obvious ones, but this is not an engineering document and is not the place for spreadsheets. How much Bitcoin one Forest Walker can mine depends on everything else. What amount of biomass can we process? Will that biomass flow enough Syngas to keep the lights on? Can the chassis support enough mining ASICs and supporting infrastructure? What does that weigh and will it affect field performance? How much power can the AC generator produce?
Other questions that are more philosophical persist. Even if a single Forest Walker can only mine scant amounts of BTC per day, that pales to how much fuel material it can process into biochar. We are talking about millions upon millions of forested acres in need of fuel load management. What can a single Forest Walker do? I am not thinking in singular terms. The Forest Walker must operate as a fleet. What could 50 do? 500?
What is it worth providing a service to the world by managing forest fuel loads? Providing proof of work to the global monetary system? Seeding soil with drought and nutrient resilience by the excretion, over time, of carbon by the ton? What did the last forest fire cost?
The Mesh Network
What could be better than one bitcoin mining, carbon sequestering, forest fire squelching, soil amending behemoth? Thousands of them, but then they would need to be able to talk to each other to coordinate position, data handling, etc. Fitted with a mesh networking device, like goTenna or Meshtastic LoRa equipment enables each Forest Walker to communicate with each other.
Now we have an interconnected fleet of Forest Walkers relaying data to each other and more importantly, aggregating all of that to the last link in the chain for uplink. Well, at least Bitcoin mining data. Since block data is lightweight, transmission of these data via mesh networking in fairly close quartered environs is more than doable. So, how does data transmit to the Bitcoin Network? How do the Forest Walkers get the previous block data necessary to execute on mining?
Back To The Chain
Getting Bitcoin block data to and from the network is the last puzzle piece. The standing presumption here is that wherever a Forest Walker fleet is operating, it is NOT within cell tower range. We further presume that the nearest Walmart Wi-Fi is hours away. Enter the Blockstream Satellite or something like it.
A separate, ground-based drone will have two jobs: To stay as close to the nearest Forest Walker as it can and to provide an antennae for either terrestrial or orbital data uplink. Bitcoin-centric data is transmitted to the "uplink drone" via the mesh networked transmitters and then sent on to the uplink and the whole flow goes in the opposite direction as well; many to one and one to many.
We cannot transmit data to the Blockstream satellite, and it will be up to Blockstream and companies like it to provide uplink capabilities in the future and I don't doubt they will. Starlink you say? What’s stopping that company from filtering out block data? Nothing because it’s Starlink’s system and they could decide to censor these data. It seems we may have a problem sending and receiving Bitcoin data in back country environs.
But, then again, the utility of this system in staunching the fuel load that creates forest fires is extremely useful around forested communities and many have fiber, Wi-Fi and cell towers. These communities could be a welcoming ground zero for first deployments of the Forest Walker system by the home and business owners seeking fire repression. In the best way, Bitcoin subsidizes the safety of the communities.
Sensor Packages
LiDaR
The benefit of having a Forest Walker fleet strolling through the forest is the never ending opportunity for data gathering. A plethora of deployable sensors gathering hyper-accurate data on everything from temperature to topography is yet another revenue generator. Data is valuable and the Forest Walker could generate data sales to various government entities and private concerns.
LiDaR (Light Detection and Ranging) can map topography, perform biomass assessment, comparative soil erosion analysis, etc. It so happens that the Forest Walker’s ability to “see,” to navigate about its surroundings, is LiDaR driven and since it’s already being used, we can get double duty by harvesting that data for later use. By using a laser to send out light pulses and measuring the time it takes for the reflection of those pulses to return, very detailed data sets incrementally build up. Eventually, as enough data about a certain area becomes available, the data becomes useful and valuable.
Forestry concerns, both private and public, often use LiDaR to build 3D models of tree stands to assess the amount of harvest-able lumber in entire sections of forest. Consulting companies offering these services charge anywhere from several hundred to several thousand dollars per square kilometer for such services. A Forest Walker generating such assessments on the fly while performing its other functions is a multi-disciplinary approach to revenue generation.
pH, Soil Moisture, and Cation Exchange Sensing
The Forest Walker is quadrupedal, so there are four contact points to the soil. Why not get a pH data point for every step it takes? We can also gather soil moisture data and cation exchange capacities at unheard of densities because of sampling occurring on the fly during commission of the system’s other duties. No one is going to build a machine to do pH testing of vast tracts of forest soils, but that doesn’t make the data collected from such an endeavor valueless. Since the Forest Walker serves many functions at once, a multitude of data products can add to the return on investment component.
Weather Data
Temperature, humidity, pressure, and even data like evapotranspiration gathered at high densities on broad acre scales have untold value and because the sensors are lightweight and don’t require large power budgets, they come along for the ride at little cost. But, just like the old mantra, “gas, grass, or ass, nobody rides for free”, these sensors provide potential revenue benefits just by them being present.
I’ve touched on just a few data genres here. In fact, the question for universities, governmental bodies, and other institutions becomes, “How much will you pay us to attach your sensor payload to the Forest Walker?”
Noise Suppression
Only you can prevent Metallica filling the surrounds with 120 dB of sound. Easy enough, just turn the car stereo off. But what of a fleet of 50 Forest Walkers operating in the backcountry or near a township? 500? 5000? Each one has a wood chipper, an internal combustion engine, hydraulic pumps, actuators, and more cooling fans than you can shake a stick at. It’s a walking, screaming fire-breathing dragon operating continuously, day and night, twenty-four hours a day, three hundred sixty-five days a year. The sound will negatively affect all living things and that impacts behaviors. Serious engineering consideration and prowess must deliver a silencing blow to the major issue of noise.
It would be foolish to think that a fleet of Forest Walkers could be silent, but if not a major design consideration, then the entire idea is dead on arrival. Townships would not allow them to operate even if they solved the problem of widespread fuel load and neither would governmental entities, and rightly so. Nothing, not man nor beast, would want to be subjected to an eternal, infernal scream even if it were to end within days as the fleet moved further away after consuming what it could. Noise and heat are the only real pollutants of this system; taking noise seriously from the beginning is paramount.
Fire Safety
A “fire-breathing dragon” is not the worst description of the Forest Walker. It eats wood, combusts it at very high temperatures and excretes carbon; and it does so in an extremely flammable environment. Bad mix for one Forest Walker, worse for many. One must take extreme pains to ensure that during normal operation, a Forest Walker could fall over, walk through tinder dry brush, or get pounded into the ground by a meteorite from Krypton and it wouldn’t destroy epic swaths of trees and baby deer. I envision an ultimate test of a prototype to include dowsing it in grain alcohol while it’s wrapped up in toilet paper like a pledge at a fraternity party. If it runs for 72 hours and doesn’t set everything on fire, then maybe outside entities won’t be fearful of something that walks around forests with a constant fire in its belly.
The Wrap
How we think about what can be done with and adjacent to Bitcoin is at least as important as Bitcoin’s economic standing itself. For those who will tell me that this entire idea is without merit, I say, “OK, fine. You can come up with something, too.” What can we plug Bitcoin into that, like a battery, makes something that does not work, work? That’s the lesson I get from this entire exercise. No one was ever going to hire teams of humans to go out and "clean the forest". There's no money in that. The data collection and sales from such an endeavor might provide revenues over the break-even point but investment demands Alpha in this day and age. But, plug Bitcoin into an almost viable system and, voilà! We tip the scales to achieve lift-off.
Let’s face it, we haven’t scratched the surface of Bitcoin’s forcing function on our minds. Not because it’s Bitcoin, but because of what that invention means. The question that pushes me to approach things this way is, “what can we create that one system’s waste is another system’s feedstock?” The Forest Walker system’s only real waste is the conversion of low entropy energy (wood and syngas) into high entropy energy (heat and noise). All other output is beneficial to humanity.
Bitcoin, I believe, is the first product of a new mode of human imagination. An imagination newly forged over the past few millennia of being lied to, stolen from, distracted and otherwise mis-allocated to a black hole of the nonsensical. We are waking up.
What I have presented is not science fiction. Everything I have described here is well within the realm of possibility. The question is one of viability, at least in terms of the detritus of the old world we find ourselves departing from. This system would take a non-trivial amount of time and resources to develop. I think the system would garner extensive long-term contracts from those who have the most to lose from wildfires, the most to gain from hyperaccurate data sets, and, of course, securing the most precious asset in the world. Many may not see it that way, for they seek Alpha and are therefore blind to other possibilities. Others will see only the possibilities; of thinking in a new way, of looking at things differently, and dreaming of what comes next.
