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.

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.

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.

2025-03-25 17:43:44One 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.

2025-03-18 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.

2025-05-01 01:51:10Please respect Virginia Giuffre’s memory by refraining from asking about the circumstances or theories surrounding her passing.
Since Virginia Giuffre’s death, I’ve reflected on what she would want me to say or do. This piece is my attempt to honor her legacy.
When I first spoke with Virginia, I was struck by her unshakable hope. I had grown cynical after years in the anti-human trafficking movement, worn down by a broken system and a government that often seemed complicit. But Virginia’s passion, creativity, and belief that survivors could be heard reignited something in me. She reminded me of my younger, more hopeful self. Instead of warning her about the challenges ahead, I let her dream big, unburdened by my own disillusionment. That conversation changed me for the better, and following her lead led to meaningful progress.
Virginia was one of the bravest people I’ve ever known. As a survivor of Epstein, Maxwell, and their co-conspirators, she risked everything to speak out, taking on some of the world’s most powerful figures.
She loved when I said, “Epstein isn’t the only Epstein.” This wasn’t just about one man—it was a call to hold all abusers accountable and to ensure survivors find hope and healing.
The Epstein case often gets reduced to sensational details about the elite, but that misses the bigger picture. Yes, we should be holding all of the co-conspirators accountable, we must listen to the survivors’ stories. Their experiences reveal how predators exploit vulnerabilities, offering lessons to prevent future victims.
You’re not powerless in this fight. Educate yourself about trafficking and abuse—online and offline—and take steps to protect those around you. Supporting survivors starts with small, meaningful actions. Free online resources can guide you in being a safe, supportive presence.
When high-profile accusations arise, resist snap judgments. Instead of dismissing survivors as “crazy,” pause to consider the trauma they may be navigating. Speaking out or coping with abuse is never easy. You don’t have to believe every claim, but you can refrain from attacking accusers online.
Society also fails at providing aftercare for survivors. The government, often part of the problem, won’t solve this. It’s up to us. Prevention is critical, but when abuse occurs, step up for your loved ones and community. Protect the vulnerable. it’s a challenging but a rewarding journey.
If you’re contributing to Nostr, you’re helping build a censorship resistant platform where survivors can share their stories freely, no matter how powerful their abusers are. Their voices can endure here, offering strength and hope to others. This gives me great hope for the future.
Virginia Giuffre’s courage was a gift to the world. It was an honor to know and serve her. She will be deeply missed. My hope is that her story inspires others to take on the powerful.

2025-05-01 01:47:10EVERY Company ไข่ขาวเชื้อรา ที่รัฐส่งเสริม Unilever อุ้ม และเราถูกคลุมถุงให้กิน
อู๊ว ฉันเกิดมาเป็นไก่ โดนคนเลี้ยงเอาไว้ วันๆไม่ต้องทำอะไร แค่กินแล้วออกไข่ ป๊อกๆๆๆๆๆ กะต๊อก ป๊อกๆๆๆ ป๊อกๆๆๆๆๆ กะต๊อก ป๊อกๆๆๆ เพลงของเป้ อารักษ์ อาจกลายเป็นแค่คำเปรียบเปรย มนุษย์ ที่ถูกริดรอนสิทธิ์ตัวเองลงทุกวันจากนักล่า https://youtu.be/RctpDMoymVw?si=D3jzUXZBmyjxKGpN
โลกยุคใหม่อาจไม่ต้องมีแม่ไก่ แค่มีเชื้อรา กับเทคโนโลยี "precision fermentation" ก็สามารถทำให้ “ไข่” โผล่ออกมาในรูปของผงโปรตีนที่ไม่เคยผ่านตูดอุ่นๆ ไม่เคยมีเสียงกุ๊กๆ และไม่เคยเจอรังเจี๊ยบอีกต่อไป แต่เบื้องหลังของไข่ทดแทนที่ว่า “ก้าวหน้า” นี้ กลับเป็นการเคลื่อนไหวที่เชื่อมโยงรัฐ ธุรกิจยักษ์ และแคมเปญแนว “greenwashing” ได้อย่างแนบเนียนแบบพิมพ์นิยมของโลกอาหารสังเคราะห์ เรื่องราวมันประมาณนี้ครับ
เมื่อไข่เกิดจากเชื้อรา The EVERY Company ซึ่งเดิมชื่อว่า Clara Foods ก่อตั้งขึ้นในปี 2014 โดย Arturo Elizondo และเพื่อนร่วมทีมที่ออกมาจากโครงการ IndieBio ซึ่งเป็น accelerator สำหรับสตาร์ทอัปด้านชีววิทยาสังเคราะห์ที่มีชื่อเสียงใน Silicon Valley ได้ใช้ยีสต์ที่ถูกดัดแปลงพันธุกรรม (GMO yeast) สายพันธุ์ Komagataella phaffii เพื่อให้มันสร้าง “ovalbumin” หรือโปรตีนไข่ขาวขึ้นมาได้ คล้ายการหลอกยีสต์ให้กลายเป็นโรงงานสร้างไข่แบบไม่ต้องมีไก่ กระบวนการหมักนี้คือการจับยีสต์ใส่ถัง เติมน้ำตาล เติมสารอาหาร แล้วรอให้มัน "ผลิต" โปรตีนในห้องแล็บ แล้วก็สกัดออกมา ทำให้บริสุทธิ์ ตากแห้ง แล้วบรรจุใส่ซอง ชูป้าย “animal-free” แปะคำว่า “sustainable” แล้วส่งเข้าสู่ตลาดโปรตีนทดแทน ผลิตภัณฑ์นี้ได้รับการรับรองจาก FDA ว่าเป็น Generally Recognized as Safe (GRAS)
แต่คำถามคือ… ยีสต์ GMO + กระบวนการหมัก = sustainable จริงหรือเปล่า?
ถึงจะเป็นโปรตีนสังเคราะห์ ที่คนแพ้ไข่ก็ยังแพ้อยู่ดี แม้จะไม่มีสัตว์เกี่ยวข้องเลย แต่ EVERY Egg White ก็ยังคงต้องติดป้าย “Contains Egg” ตามกฎหมาย เพราะโครงสร้างโปรตีนที่ผลิตออกมา "เหมือน" โปรตีนไข่จริงมากจนสามารถกระตุ้นอาการแพ้ในคนที่แพ้ไข่ได้อยู่ดี แปลว่า... เราไม่ได้หลุดพ้นจากปัญหาแพ้อาหารเลย แค่เปลี่ยนแหล่งกำเนิดจากไก่มาเป็นเชื้อรา แต่สิ่งที่น่าคิดคือ นี่แสดงว่าองค์ประกอบของมันเหมือนชนิดที่ว่า สำเนาถูกต้องขนาดคนแพ้ไข่ยังแพ้อยู่ คุณคิดว่าในมุมนี้น่าคิดกว่าไหม???
Back ดีมีกองทัพอุ้ม เงินภาษีหนุน ที่น่าจับตาคือ EVERY ได้รับเงินสนับสนุนกว่า 2 ล้านดอลลาร์จากกระทรวงกลาโหมสหรัฐฯ (DoD) เพื่อศึกษาความเป็นไปได้ในการผลิตโปรตีนในประเทศ ตัวเลขนี้ไม่ใช่เล่น ๆ แปลว่า ภาครัฐกำลังพิจารณาให้ "ไข่จากเชื้อรา" เป็นอาหารแห่งอนาคตของกองทัพ ซึ่งหมายถึงเม็ดเงินระดับพันล้านเหรียญหากแผนนี้เดินหน้า และเมื่อรัฐหนุนขนาดนี้ เทคโนโลยีที่ยังแพงก็จะ “ไม่แพง” อีกต่อไป เพราะเงินภาษีช่วยลดต้นทุนแบบกลาย ๆ เหมือนที่เคยเกิดกับ Beyond Meat หรือ Impossible Foods
เท่านั้นไม่พอครับ ไข่ขาวของท่าน ได้รับการคัดเลือกที่จะจับมือกับ The Vegetarian Butcher บริษัทลูกของ Unilever บริษัทอาหารที่ครองตลาดโลกราวกับเป็นเจ้าของตู้เย็นของประชากรโลก Unilever จะใช้โปรตีนไข่จาก EVERY ใส่ในผลิตภัณฑ์ plant-based meat ที่กำลังไต่ตลาดโลก โดยไม่จำเป็นต้องแจ้งผู้บริโภคว่าโปรตีนนี้มาจากเชื้อรา GMO หรือกระบวนการ biotech ที่ไม่ธรรมดา แม้จะถูกจัดว่าเป็น "non-animal ingredient" หรือ "ไม่ได้มาจากสัตว์โดยตรง" แต่ก็มีสิทธิ์เข้าสู่เมนูมังสวิรัติ วีแกน และอาหารเด็กได้อย่างง่ายดาย เพราะภาพจำที่สื่อมวลชนร่วมกันสร้างขึ้น เพราะไม่มีภาพของ “สัตว์” อยู่ในกระบวนการเลย จึงกลายเป็น “วีแกนได้” ในสายตาคนทั่วไป ทั้งที่ความจริงมันคือเทคโนโลยีชีวภาพระดับลึก ด้วยการใช้คำอย่าง “cruelty-free”, “animal-free”, “sustainable protein”, รวมถึงหน้าตาผลิตภัณฑ์ที่ดูใสสะอาด ไร้กลิ่นอายห้องแล็บ
แม้จะยังไม่มีหลักฐานตรงๆ ว่า EVERY เข้าล็อบบี้รัฐบาลเหมือน Oatly แต่เส้นทางที่เห็นชัดคือความร่วมมือกับองค์กรระดับนโยบาย เช่น Good Food Institute (GFI) และกลุ่มผลักดัน food-tech เพื่อก่อรูปแนวคิดว่า “อาหารที่ไม่ได้มาจากธรรมชาติ” = “อนาคต” และเมื่อแบรนด์เหล่านี้จับมือกับยักษ์ใหญ่ กลายเป็นอาหารในโรงเรียน ทหาร โรงพยาบาล หรือ planet of the future คนทั่วไปก็ไม่มีสิทธิ์เลือกอีกต่อไป เพราะทุกที่ถูกจัดสรรโดยนโยบายที่ใครบางคนได้ตัดสินไปแล้ว
EVERY Company ไม่ได้ขายแค่ไข่สังเคราะห์ แต่ขาย “อนาคตของอาหาร” แบบที่มนุษย์ถูกแยกออกจากธรรมชาติ แล้วพึ่งพาเทคโนโลยีและเงินทุนแทน และในโลกที่รัฐกับบริษัทยักษ์กำลังร่วมมือกันสร้างนิยามใหม่ของคำว่า “โปรตีนดีต่อสิ่งแวดล้อม” เราในฐานะผู้บริโภคควรถามกลับว่า…
ดีต่อใคร? ธรรมชาติ หรือห้องแล็บ? สุขภาพของมนุษย์ หรือผลกำไรของเจ้าของแพลตฟอร์มอาหาร?
***สรุป timeline เบาๆ 2014 – Clara Foods ก่อตั้งในซานฟรานซิสโก โดยมีเป้าหมายผลิต “ไข่โดยไม่ต้องใช้ไก่” ผ่านกระบวนการ fermentation 2015-2019 – รับทุนหลายรอบ รวมถึงจาก Horizons Ventures (ที่ลงทุนใน Impossible Foods), IndieBio, Blue Horizon ฯลฯ 2021 – เปลี่ยนชื่อจาก Clara Foods เป็น The EVERY Company เพื่อสะท้อนเป้าหมายที่กว้างขึ้น: การสร้างโปรตีน “EVERYthing” จากจุลชีพ

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.

2025-03-13 19:39:28In 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.

2025-03-12 00:40:25Before I saw those X right-wing political “influencers” parading their Epstein binders in that PR stunt, I’d already posted this on Nostr, an open protocol.
“Today, the world’s attention will likely fixate on Epstein, governmental failures in addressing horrific abuse cases, and the influential figures who perpetrate such acts—yet few will center the victims and survivors in the conversation. The survivors of Epstein went to law enforcement and very little happened. The survivors tried to speak to the corporate press and the corporate press knowingly covered for him. In situations like these social media can serve as one of the only ways for a survivor’s voice to be heard.
It’s becoming increasingly evident that the line between centralized corporate social media and the state is razor-thin, if it exists at all. Time and again, the state shields powerful abusers when it’s politically expedient to do so. In this climate, a survivor attempting to expose someone like Epstein on a corporate tech platform faces an uphill battle—there’s no assurance their voice would even break through. Their story wouldn’t truly belong to them; it’d be at the mercy of the platform, subject to deletion at a whim. Nostr, though, offers a lifeline—a censorship-resistant space where survivors can share their truths, no matter how untouchable the abuser might seem. A survivor could remain anonymous here if they took enough steps.
Nostr holds real promise for amplifying survivor voices. And if you’re here daily, tossing out memes, take heart: you’re helping build a foundation for those who desperately need to be heard.“
That post is untouchable—no CEO, company, employee, or government can delete it. Even if I wanted to, I couldn’t take it down myself. The post will outlive me on the protocol.
The cozy alliance between the state and corporate social media hit me hard during that right-wing X “influencer” PR stunt. Elon owns X. Elon’s a special government employee. X pays those influencers to post. We don’t know who else pays them to post. Those influencers are spurred on by both the government and X to manage the Epstein case narrative. It wasn’t survivors standing there, grinning for photos—it was paid influencers, gatekeepers orchestrating yet another chance to re-exploit the already exploited.
The bond between the state and corporate social media is tight. If the other Epsteins out there are ever to be unmasked, I wouldn’t bet on a survivor’s story staying safe with a corporate tech platform, the government, any social media influencer, or mainstream journalist. Right now, only a protocol can hand survivors the power to truly own their narrative.
I don’t have anything against Elon—I’ve actually been a big supporter. I’m just stating it as I see it. X isn’t censorship resistant and they have an algorithm that they choose not the user. Corporate tech platforms like X can be a better fit for some survivors. X has safety tools and content moderation, making it a solid option for certain individuals. Grok can be a big help for survivors looking for resources or support! As a survivor, you know what works best for you, and safety should always come first—keep that front and center.
That said, a protocol is a game-changer for cases where the powerful are likely to censor. During China's # MeToo movement, survivors faced heavy censorship on social media platforms like Weibo and WeChat, where posts about sexual harassment were quickly removed, and hashtags like # MeToo or "woyeshi" were blocked by government and platform filters. To bypass this, activists turned to blockchain technology encoding their stories—like Yue Xin’s open letter about a Peking University case—into transaction metadata. This made the information tamper-proof and publicly accessible, resisting censorship since blockchain data can’t be easily altered or deleted.
I posted this on X 2/28/25. I wanted to try my first long post on a nostr client. The Epstein cover up is ongoing so it’s still relevant, unfortunately.
If you are a survivor or loved one who is reading this and needs support please reach out to: National Sexual Assault Hotline 24/7 https://rainn.org/

2025-03-10 23:31:30Bitcoin 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.
Usually stolen bitcoin for the reserve creates a perverse incentive. If governments see a 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.

2025-03-10 12:09:35At this point, we should be arresting, not firing, any FBI employee who delays, destroys, or withholds information on the Epstein case. There is ZERO explanation I will accept for redacting anything for “national security” reasons. A lot of Trump supporters are losing patience with Pam Bondi. I will give her the benefit of the doubt for now since the corruption within the whole security/intelligence apparatus of our country runs deep. However, let’s not forget that probably Trump’s biggest mistakes in his first term involved picking weak and easily corruptible (or blackmailable) officials. It seemed every month a formerly-loyal person did a complete 180 degree turn and did everything they could to screw him over, regardless of the betrayal’s effect on the country or whatever principles that person claimed to have. I think he’s fixed his screening process, but since we’re talking about the FBI, we know they have the power to dig up any dirt or blackmail material available, or just make it up. In the Epstein case, it’s probably better to go after Bondi than give up a treasure trove of blackmail material against the long list of members on his client list.

2025-03-10 00:32:44Recentemente, assisti a um vídeo que me fez refletir profundamente sobre o impacto da linguagem na hora de vender. No vídeo, uma jovem relatava sua experiência ao presenciar um vendedor de amendoim em uma agência dos Correios. O local estava cheio, as pessoas aguardavam impacientes na fila e, em meio a esse cenário, um homem humilde tentava vender seu produto. Mas sua abordagem não era estratégica; ao invés de destacar os benefícios do amendoim, ele suplicava para que alguém o ajudasse comprando. O resultado? Ninguém se interessou.
A jovem observou que o problema não era o produto, mas a forma como ele estava sendo oferecido. Afinal, muitas das pessoas ali estavam há horas esperando e perto do horário do almoço – o amendoim poderia ser um ótimo tira-gosto. No entanto, como a comunicação do vendedor vinha carregada de desespero, ele afastava os clientes ao invés de atraí-los. Esse vídeo me tocou profundamente.
No dia seguinte, ao sair para comemorar meu aniversário, vi um menino vendendo balas na rua, sob o sol forte. Assim como no caso do amendoim, percebi que as pessoas ao redor não se interessavam por seu produto. Ao se aproximar do carro, resolvi comprar dois pacotes. Mais do que ajudar, queria que aquele pequeno gesto servisse como incentivo para que ele continuasse acreditando no seu negócio.
Essa experiência me fez refletir ainda mais sobre o poder da comunicação em vendas. Muitas vezes, não é o produto que está errado, mas sim a forma como o vendedor o apresenta. Quando transmitimos confiança e mostramos o valor do que vendemos, despertamos o interesse genuíno dos clientes.
Como a Linguagem Impacta as Vendas?
1. O Poder da Abordagem Positiva
Em vez de pedir por ajuda, é importante destacar os benefícios do produto. No caso do amendoim, o vendedor poderia ter dito algo como: "Que tal um petisco delicioso enquanto espera? Um amendoim fresquinho para matar a fome até o almoço!"
2. A Emoção na Medida Certa
Expressar emoção é essencial, mas sem parecer desesperado. Os clientes devem sentir que estão adquirindo algo de valor, não apenas ajudando o vendedor.
3. Conheça Seu Público
Entender o contexto é fundamental. Se as pessoas estavam com fome e impacientes, uma abordagem mais objetiva e focada no benefício do produto poderia gerar mais vendas.
4. Autoconfiança e Postura
Falar com firmeza e segurança transmite credibilidade. O vendedor precisa acreditar no próprio produto antes de convencer o cliente a comprá-lo.
Conclusão
Vender é mais do que apenas oferecer um produto – é uma arte que envolve comunicação, percepção e estratégia. Pequenos ajustes na abordagem podem transformar completamente os resultados. Se o vendedor de amendoim tivesse apresentado seu produto de outra maneira, talvez tivesse vendido tudo rapidamente. Da mesma forma, se cada um de nós aprender a se comunicar melhor em nossas próprias áreas, poderemos alcançar muito mais sucesso.
E você? Já passou por uma experiência parecida?

2025-03-08 00:38:481. O que é um Aromaterapeuta?
O aromaterapeuta é um profissional especializado na prática da Aromaterapia, responsável pelo uso adequado de óleos essenciais, ervas aromáticas, águas florais e destilados herbais para fins terapêuticos.
A atuação desse profissional envolve diferentes métodos de aplicação, como inalação, uso tópico, sempre considerando a segurança e a necessidade individual do cliente. A Aromaterapia pode auxiliar na redução do estresse, alívio de dores crônicas, relaxamento muscular e melhora da respiração, entre outros benefícios.
Além disso, os aromaterapeutas podem trabalhar em conjunto com outros profissionais da saúde para oferecer um tratamento complementar em diversas condições. Como já mencionado no artigo sobre "Como evitar processos alérgicos na prática da Aromaterapia", é essencial ter acompanhamento profissional, pois os óleos essenciais são altamente concentrados e podem causar reações adversas se utilizados de forma inadequada.
2. Como um Aromaterapeuta Pode Ajudar?
Você pode procurar um aromaterapeuta para diferentes necessidades, como:
✔ Questões Emocionais e Psicológicas
Auxílio em momentos de luto, divórcio, demissão ou outras situações desafiadoras.
Apoio na redução do estresse, ansiedade e insônia.
Vale lembrar que, em casos de transtornos psiquiátricos, a Aromaterapia deve ser usada como terapia complementar, associada ao tratamento médico.
✔ Questões Físicas
Dores musculares e articulares.
Problemas respiratórios como rinite, sinusite e tosse.
Distúrbios digestivos leves.
Dores de cabeça e enxaquecas. Nesses casos, a Aromaterapia pode ser um suporte, mas não substitui a medicina tradicional para identificar a origem dos sintomas.
✔ Saúde da Pele e Cabelos
Tratamento para acne, dermatites e psoríase.
Cuidados com o envelhecimento precoce da pele.
Redução da queda de cabelo e controle da oleosidade do couro cabeludo.
✔ Bem-estar e Qualidade de Vida
Melhora da concentração e foco, aumentando a produtividade.
Estímulo da disposição e energia.
Auxílio no equilíbrio hormonal (TPM, menopausa, desequilíbrios hormonais).
Com base nessas necessidades, o aromaterapeuta irá indicar o melhor tratamento, calculando doses, sinergias (combinação de óleos essenciais), diluições e técnicas de aplicação, como inalação, uso tópico ou difusão.
3. Como Funciona uma Consulta com um Aromaterapeuta?
Uma consulta com um aromaterapeuta é um atendimento personalizado, onde são avaliadas as necessidades do cliente para a criação de um protocolo adequado. O processo geralmente segue estas etapas:
✔ Anamnese (Entrevista Inicial)
Perguntas sobre saúde física, emocional e estilo de vida.
Levantamento de sintomas, histórico médico e possíveis alergias.
Definição dos objetivos da terapia (alívio do estresse, melhora do sono, dores musculares etc.).
✔ Escolha dos Óleos Essenciais
Seleção dos óleos mais indicados para o caso.
Consideração das propriedades terapêuticas, contraindicações e combinações seguras.
✔ Definição do Método de Uso
O profissional indicará a melhor forma de aplicação, que pode ser:
Inalação: difusores, colares aromáticos, vaporização.
Uso tópico: massagens, óleos corporais, compressas.
Banhos aromáticos e escalda-pés. Todas as diluições serão ajustadas de acordo com a segurança e a necessidade individual do cliente.
✔ Plano de Acompanhamento
Instruções detalhadas sobre o uso correto dos óleos essenciais.
Orientação sobre frequência e duração do tratamento.
Possibilidade de retorno para ajustes no protocolo.
A consulta pode ser realizada presencialmente ou online, dependendo do profissional.

2025-03-04 17:00:18This piece is the first in a series that will focus on things I think are a priority if your focus is similar to mine: building a strong family and safeguarding their future.
Choosing the ideal place to raise a family is one of the most significant decisions you will ever make. For simplicity sake I will break down my thought process into key factors: strong property rights, the ability to grow your own food, access to fresh water, the freedom to own and train with guns, and a dependable community.
A Jurisdiction with Strong Property Rights
Strong property rights are essential and allow you to build on a solid foundation that is less likely to break underneath you. Regions with a history of limited government and clear legal protections for landowners are ideal. Personally I think the US is the single best option globally, but within the US there is a wide difference between which state you choose. Choose carefully and thoughtfully, think long term. Obviously if you are not American this is not a realistic option for you, there are other solid options available especially if your family has mobility. I understand many do not have this capability to easily move, consider that your first priority, making movement and jurisdiction choice possible in the first place.
Abundant Access to Fresh Water
Water is life. I cannot overstate the importance of living somewhere with reliable, clean, and abundant freshwater. Some regions face water scarcity or heavy regulations on usage, so prioritizing a place where water is plentiful and your rights to it are protected is critical. Ideally you should have well access so you are not tied to municipal water supplies. In times of crisis or chaos well water cannot be easily shutoff or disrupted. If you live in an area that is drought prone, you are one drought away from societal chaos. Not enough people appreciate this simple fact.
Grow Your Own Food
A location with fertile soil, a favorable climate, and enough space for a small homestead or at the very least a garden is key. In stable times, a small homestead provides good food and important education for your family. In times of chaos your family being able to grow and raise healthy food provides a level of self sufficiency that many others will lack. Look for areas with minimal restrictions, good weather, and a culture that supports local farming.
Guns
The ability to defend your family is fundamental. A location where you can legally and easily own guns is a must. Look for places with a strong gun culture and a political history of protecting those rights. Owning one or two guns is not enough and without proper training they will be a liability rather than a benefit. Get comfortable and proficient. Never stop improving your skills. If the time comes that you must use a gun to defend your family, the skills must be instinct. Practice. Practice. Practice.
A Strong Community You Can Depend On
No one thrives alone. A ride or die community that rallies together in tough times is invaluable. Seek out a place where people know their neighbors, share similar values, and are quick to lend a hand. Lead by example and become a good neighbor, people will naturally respond in kind. Small towns are ideal, if possible, but living outside of a major city can be a solid balance in terms of work opportunities and family security.
Let me know if you found this helpful. My plan is to break down how I think about these five key subjects in future posts.

2025-02-27 21:32:12GA, plebs. The latest episode of Bitcoin And is out, and, as always, the chicanery is running rampant. Let’s break down the biggest topics I covered, and if you want the full, unfiltered rant, make sure to listen to the episode linked below.
House Democrats’ MEME Act: A Bad Joke?
House Democrats are proposing a bill to ban presidential meme coins, clearly aimed at Trump’s and Melania’s ill-advised token launches. While grifters launching meme coins is bad, this bill is just as ridiculous. If this legislation moves forward, expect a retaliatory strike exposing how politicians like Pelosi and Warren mysteriously amassed their fortunes. Will it pass? Doubtful. But it’s another sign of the government’s obsession with regulating everything except itself.
Senate Banking’s First Digital Asset Hearing: The Real Target Is You
Cynthia Lummis chaired the first digital asset hearing, and—surprise!—it was all about control. The discussion centered on stablecoins, AML, and KYC regulations, with witnesses suggesting Orwellian measures like freezing stablecoin transactions unless pre-approved by authorities. What was barely mentioned? Bitcoin. They want full oversight of stablecoins, which is really about controlling financial freedom. Expect more nonsense targeting self-custody wallets under the guise of stopping “bad actors.”
Bank of America and PayPal Want In on Stablecoins
Bank of America’s CEO openly stated they’ll launch a stablecoin as soon as regulation allows. Meanwhile, PayPal’s CEO paid for a hat using Bitcoin—not their own stablecoin, Pi USD. Why wouldn’t he use his own product? Maybe he knows stablecoins aren’t what they’re hyped up to be. Either way, the legacy financial system is gearing up to flood the market with stablecoins, not because they love crypto, but because it’s a tool to extend U.S. dollar dominance.
MetaPlanet Buys the Dip
Japan’s MetaPlanet issued $13.4M in bonds to buy more Bitcoin, proving once again that institutions see the writing on the wall. Unlike U.S. regulators who obsess over stablecoins, some companies are actually stacking sats.
UK Expands Crypto Seizure Powers
Across the pond, the UK government is pushing legislation to make it easier to seize and destroy crypto linked to criminal activity. While they frame it as going after the bad guys, it’s another move toward centralized control and financial surveillance.
Bitcoin Tools & Tech: Arc, SatoChip, and Nunchuk
Some bullish Bitcoin developments: ARC v0.5 is making Bitcoin’s second layer more efficient, SatoChip now supports Taproot and Nostr, and Nunchuk launched a group wallet with chat, making multisig collaboration easier.
The Bottom Line
The state is coming for financial privacy and control, and stablecoins are their weapon of choice. Bitcoiners need to stay focused, keep their coins in self-custody, and build out parallel systems. Expect more regulatory attacks, but don’t let them distract you—just keep stacking and transacting in ways they can’t control.

2025-04-30 02:51:3350by40 คืออีกโครงการนึงที่ขยายภาพรวมขึ้นมาอีก recap กันครับ (ใครที่มาเจอกลางทาง อาจต้องย้อนเยอะครับ ย้อนไปสัก ปลายเดือน มีนาคม 2025) หลังจากที่เราได้ดูส่วนเล็กกันมาหลายตอน ตั้งแต่เรื่องเล็กๆอย่าง น้ำมันมะกอกปลอม ซึ่งตอนนั้นหลายคนที่อ่านอาจคิดว่า ไกลตัวส่วนใหญ่ยังดีพอ แต่ความนัยที่ซ่อนไว้ในบทนั้นคือ จุดเริ่มของการทำลายความเชื่อใจในอาหาร , ที่มาของบรอกโคลีเพื่อให้รู้ว่า สิ่งที่คิดว่าธรรมชาติ มันไม่ธรรมชาติ, นมโอ้ต นมประดิษฐ์ที่เป็นจุดที่เราคิดว่ามันคือการพลิกวงการแล้ว, การแอบจดสิทธิบัตรเมล็ดพันธุ์ที่เคยปลูกกินอย่างอิสระ, การพัฒนา GMO 2.0 ที่ไม่ต้องเรียกว่า GMO, โปรตีนจากแลป มาจนถึงเวย์ที่ไม่มีวัว แล้วเราก็ขยายภาพขึ้นกับข้อกำหนดการควบคุมการปลูกพืช UPOV1991/CPTPP, การเข้าสู่โรงเรียน, การกำเนิดของ ProVeg แล้วเราก็ได้รู้จักกับ Sebastian Joy ก็ถือว่าเดินทางมา 1 ด่านแล้วครับ หนทางเรื่องนี้ยังอีกยาวไกล วันนี้เราก็มาคุยกันถึงเรื่อง
โครงการ 50by40
โครงการนี้เริ่มต้นขึ้นในเดือนเมษายน ปี 2018 โดยมีการจัดการประชุม "50by40 Corporate Outreach Summit" ระหว่างวันที่ 27–29 เมษายน 2018 ที่กรุงเบอร์ลิน ประเทศเยอรมนี ซึ่งจัดโดย ProVeg International ร่วมกับ Humane Society of the United States การประชุมนี้ถือเป็นจุดเริ่มต้นของพันธมิตรระดับโลกที่มีเป้าหมายร่วมกันในการลดการผลิตและบริโภคผลิตภัณฑ์จากสัตว์ลง 50% ภายในปี 2040
Sebastian Joy ผู้ก่อตั้งและประธานของ ProVeg International มีบทบาทสำคัญในการริเริ่มโครงการ 50by40 โดยเขาได้ช่วยก่อตั้งพันธมิตรนี้เพื่อส่งเสริมการเปลี่ยนแปลงระบบอาหารโลก นอกจากนี้ ProVeg International ยังมีบทบาทในการสนับสนุนองค์กรและสตาร์ทอัพที่มุ่งเน้นการเปลี่ยนแปลงระบบอาหารผ่านโปรแกรมต่างๆ
แม้ว่าโครงการ 50by40 จะประกาศเป้าหมายในการลดการบริโภคผลิตภัณฑ์จากสัตว์เพื่อสุขภาพและสิ่งแวดล้อม แต่เบื้องหลังยังมีการดำเนินงานที่มุ่งเน้นการเปลี่ยนแปลงระบบอาหารโลก โดยการส่งเสริม "อาหารที่เพาะเลี้ยงในห้องปฏิบัติการเป็นหลัก"
โครงการนี้ยังมีการจัดกิจกรรมเพื่อดึงดูดนักลงทุนและผู้สนับสนุนทางการเงิน เช่น การจัดงาน Food Funders Circle ซึ่งเป็นเวทีสำหรับนักลงทุนที่สนใจในอาหารทางเลือก นอกจากนี้ โครงการ 50by40 ยังมีความสัมพันธ์กับองค์กรต่างๆ ทั้งภาครัฐและเอกชน รวมถึงองค์กรระดับนานาชาติ เช่น Greenpeace, WWF และ Compassion in World Farming ซึ่งมีเป้าหมายร่วมกันในการลดการบริโภคผลิตภัณฑ์จากสัตว์ และ ProVeg International เองก็มีสถานะเป็นผู้สังเกตการณ์ถาวรในองค์การสหประชาชาติ เช่น UNFCCC, IPCC และ CBD รวมถึงมีสถานะที่ปรึกษาพิเศษกับ ECOSOC และได้รับการรับรองจาก UNEA อีกด้วย ถ้ามองแค่เนทเวิร์คเบื้องต้นแล้ว วินาทีนี้ ตอบได้เลยครับว่า "อาหารที่เพาะเลี้ยงในห้องปฏิบัติการเป็นหลัก" มาแน่นอนครับ มองข้ามความ plant based / animal based ได้เลย
เพื่อบรรลุเป้าหมายนี้ โครงการได้ดำเนินกิจกรรมต่างๆ ทั้งในระดับโรงเรียนและการผลักดันนโยบายสาธารณะ ผมจะลองแบ่งเป็นข้อๆให้เพื่อความสะดวกในการมองภาพรวมประมาณนี้นะครับ
การดำเนินงานในโรงเรียนและเยาวชน 1. Early Action Network โครงการนี้เป็นความร่วมมือระหว่าง 50by40, ProVeg International และ Educated Choices Program โดยมีเป้าหมายในการส่งเสริมการบริโภคอาหารจากพืชในกลุ่มเด็กและเยาวชนผ่านกิจกรรมต่างๆ เช่น การจัดกิจกรรมเชิงโต้ตอบเกี่ยวกับสุขภาพ สิ่งแวดล้อม และสวัสดิภาพสัตว์, การจัดแคมเปญในโรงเรียนและชุมชน, การเผยแพร่สื่อการเรียนรู้และโปรแกรมฝึกอบรม, การปรับปรุงเมนูอาหารในโรงเรียนให้มีทางเลือกจากพืชมากขึ้น
โครงการนี้มุ่งหวังที่จะสร้างความตระหนักรู้และเปลี่ยนแปลงพฤติกรรมการบริโภคของเยาวชนตั้งแต่เนิ่นๆ เพื่อส่งเสริมการบริโภคอาหารที่ยั่งยืนและเป็นมิตรกับสิ่งแวดล้อม
- School Plates Programme ProVeg International ได้เปิดตัวโครงการ School Plates ในสหราชอาณาจักรเมื่อปี 2018 โดยมีเป้าหมายในการปรับปรุงเมนูอาหารในโรงเรียนให้มีความหลากหลายและสุขภาพดีขึ้นผ่านการเพิ่มทางเลือกอาหารจากพืช โครงการนี้ได้ร่วมมือกับโรงเรียน หน่วยงานท้องถิ่น และบริษัทจัดเลี้ยง เพื่อเปลี่ยนแปลงเมนูอาหารในโรงเรียนกว่า 3.1 ล้านมื้อจากอาหารที่มีเนื้อสัตว์เป็นหลักไปเป็นอาหารจากพืช
สำหรับในส่วนของการผลักดันนโยบายสาธารณะและการมีส่วนร่วมในเวทีนานาชาตินั้น ก็มีไม่น้อยครับ อาทิเช่น การมีส่วนร่วมในองค์การสหประชาชาติ ProVeg International มีสถานะเป็นผู้สังเกตการณ์ถาวรในองค์การสหประชาชาติ เช่น UNFCCC และ UNEP และได้มีบทบาทในการผลักดันให้มีการรวมประเด็นเกี่ยวกับอาหารจากพืชในการเจรจาด้านสภาพภูมิอากาศ โดยในปี 2022 ProVeg ได้เข้าร่วมการประชุมสภาพภูมิอากาศของสหประชาชาติในสตอกโฮล์มและบอนน์ เพื่อส่งเสริมแนวคิด "Diet Change Not Climate Change" และเรียกร้องให้มีการเปลี่ยนแปลงระบบอาหารสู่การบริโภคอาหารจากพืชมากขึ้น
การสนับสนุนเยาวชนในเวทีนานาชาติ ProVeg ได้จัดตั้ง Youth Board ซึ่งประกอบด้วยเยาวชนจากทั่วโลก เพื่อมีส่วนร่วมในการผลักดันนโยบายด้านอาหารจากพืชในเวทีสหประชาชาติ และเตรียมความพร้อมสำหรับการประชุม COP30 ที่จะจัดขึ้นในเบเลง ประเทศบราซิล
นอกจากนี้ยังมีการสนับสนุนองค์กรและสตาร์ทอัพที่มุ่งเปลี่ยนแปลงระบบอาหารอีกมากมาย โดยที่โดดเด่นเป็นพิเศษคือ โปรแกรม Kickstarting for Good ProVeg International ได้เปิดตัวโปรแกรม Kickstarting for Good ซึ่งเป็นโปรแกรมบ่มเพาะและเร่งการเติบโตสำหรับองค์กรไม่แสวงหาผลกำไร โครงการที่มีผลกระทบ และสตาร์ทอัพทางสังคมที่มุ่งเปลี่ยนแปลงระบบอาหาร โปรแกรมนี้มีระยะเวลา 8 สัปดาห์ โดยมีการฝึกอบรมแบบเข้มข้น การให้คำปรึกษาจากผู้เชี่ยวชาญ และโอกาสในการสร้างเครือข่าย เพื่อสนับสนุนการพัฒนาโครงการที่มีศักยภาพในการลดการบริโภคผลิตภัณฑ์จากสัตว์และส่งเสริมอาหารจากพืช
นอกจาก Sebastian Joy จะเริ่มต้นโครงการต่างๆมากมายไม่ว่าจะ ProVeg International, ProVeg Incubator, Kickstarting for Good แต่ก็ยังมี องค์กรพันธมิตรในเครือข่าย 50by40 ที่หลากหลาย เช่น Plant Powered Metro New York, Public Justice, Rainforest Alliance, Real Food Systems, Reducetarian Foundation, Rethink Your Food, SEED และ Seeding Sovereignty ซึ่งร่วมกันส่งเสริมการบริโภคอาหารจากพืชและการลดการบริโภคผลิตภัณฑ์จากสัตว์ แม้ว่าโครงการ 50by40 จะได้รับการสนับสนุนจากองค์กรต่างๆ อย่างกว้างขวาง แต่ยังไม่มีข้อมูลที่ชัดเจนเกี่ยวกับบริษัทเอกชนรายใดที่แสดงการสนับสนุนโครงการนี้อย่างเปิดเผยครับ
ทีนี้เรามาดูความเคลื่อนไหวของลูกพี่ใหญ่อย่าง USDA กันบ้างนะครับ จากการตรวจสอบข้อมูลที่มีอยู่จนถึงปัจจุบัน ยังไม่พบหลักฐานชัดเจนว่า กระทรวงเกษตรสหรัฐฯ (USDA) มีการสนับสนุนโครงการ 50by40 อย่างเป็นทางการหรือเปิดเผย อย่างไรก็ตาม มีความเคลื่อนไหวที่เกี่ยวข้องกับการส่งเสริมโปรตีนทางเลือกและการลดการบริโภคเนื้อสัตว์ในระดับนโยบายของสหรัฐฯ ซึ่งอาจสอดคล้องกับเป้าหมายของโครงการ 50by40 อยู่เช่นกันครับ
ในปี 2021 คณะกรรมาธิการด้านการเกษตรของสภาผู้แทนราษฎรสหรัฐฯ ได้สนับสนุนให้ USDA จัดสรรงบประมาณ 50 ล้านดอลลาร์สหรัฐฯ ผ่านโครงการ Agriculture and Food Research Initiative (AFRI) เพื่อสนับสนุนการวิจัยเกี่ยวกับโปรตีนทางเลือก เช่น การใช้พืช การเพาะเลี้ยงเซลล์ และการหมัก เพื่อพัฒนาอาหารที่มีคุณสมบัติคล้ายเนื้อสัตว์
นอกจากนี้ USDA ได้ยอมรับคำว่า "cell-cultured" เป็นคำที่ใช้เรียกเนื้อสัตว์ที่ผลิตจากการเพาะเลี้ยงเซลล์ในห้องปฏิบัติการ ซึ่งเป็นส่วนหนึ่งของการกำหนดมาตรฐานและการควบคุมผลิตภัณฑ์อาหารใหม่ๆ ที่เกี่ยวข้องกับโปรตีนทางเลือก
แล้วกลุ่มองค์กรด้านสิ่งแวดล้อมและสุขภาพ เช่น Center for Biological Diversity ได้ส่งจดหมายถึงรัฐมนตรีกระทรวงเกษตรสหรัฐฯ เรียกร้องให้ USDA นำประเด็นการลดการบริโภคเนื้อสัตว์และผลิตภัณฑ์นมมาเป็นส่วนหนึ่งของยุทธศาสตร์ด้านสภาพภูมิอากาศ และปรับปรุงแนวทางโภชนาการแห่งชาติให้สอดคล้องกับเป้าหมาย "ด้านความยั่งยืน"
แม้ว่า USDA จะไม่ได้แสดงการสนับสนุนโครงการ 50by40 โดยตรง แต่มีความร่วมมือกับองค์กรที่มีเป้าหมายคล้ายคลึงกัน เช่น ProVeg International และ The Good Food Institute ซึ่งเป็นพันธมิตรในเครือข่ายของ 50by40 โดยมีเป้าหมายในการส่งเสริมการบริโภคอาหารจากการเพาะเลี้ยงเซลล์ในห้องปฏิบัติการและโปรตีนทางเลือก
อนาคตได้มีการขีด Goal ไว้ประมาณนี้ เรายังคิดว่าการที่ "แค่ไม่กินมัน" "ก็แค่เลือกกินอาหารธรรมชาติ" จะยังเป็นคำพูดที่เราพูดได้อีกไหม สิ่งนี้ก็ยังเป็นคำถามต่อไปครับ คงไม่มีใครสามารถตอบได้ใน วันนี้ (มั๊ง)
แต่ที่แน่ๆ มีคนไม่น้อยแล้วแหละครับ ที่บอกว่าอาหารจากแลปคุมในโรงงานที่สะอาด มันก็ดีนี่ สะอาดปลอดภัย ดีกว่าเนื้อหมูที่ผัดข้างทาง ล้างหรือเปล่าก็ไม่รู้ เอาหมูแบบไหนมาก็ไม่รู้
มันดูเหมือนว่าเป็นการเปรียบเปรยแบบตรรกะวิบัตินะครับ แต่รอบตัวคุณ มีคนคิดแบบนี้เยอะไหม? เป็นคำถามที่ไม่มีคำตอบอีกเช่นกันครับ

2025-02-21 18:15:52"Malcolm Forbes recounts that a lady, wearing a faded cotton dress, and her husband, dressed in an old handmade suit, stepped off a train in Boston, USA, and timidly made their way to the office of the president of Harvard University. They had come from Palo Alto, California, and had not scheduled an appointment. The secretary, at a glance, thought that those two, looking like country bumpkins, had no business at Harvard.
— We want to speak with the president — the man said in a low voice.
— He will be busy all day — the secretary replied curtly.
— We will wait.
The secretary ignored them for hours, hoping the couple would finally give up and leave. But they stayed there, and the secretary, somewhat frustrated, decided to bother the president, although she hated doing that.
— If you speak with them for just a few minutes, maybe they will decide to go away — she said.
The president sighed in irritation but agreed. Someone of his importance did not have time to meet people like that, but he hated faded dresses and tattered suits in his office. With a stern face, he went to the couple.
— We had a son who studied at Harvard for a year — the woman said. — He loved Harvard and was very happy here, but a year ago he died in an accident, and we would like to erect a monument in his honor somewhere on campus.— My lady — said the president rudely —, we cannot erect a statue for every person who studied at Harvard and died; if we did, this place would look like a cemetery.
— Oh, no — the lady quickly replied. — We do not want to erect a statue. We would like to donate a building to Harvard.
The president looked at the woman's faded dress and her husband's old suit and exclaimed:
— A building! Do you have even the faintest idea of how much a building costs? We have more than seven and a half million dollars' worth of buildings here at Harvard.
The lady was silent for a moment, then said to her husband:
— If that’s all it costs to found a university, why don’t we have our own?
The husband agreed.
The couple, Leland Stanford, stood up and left, leaving the president confused. Traveling back to Palo Alto, California, they established there Stanford University, the second-largest in the world, in honor of their son, a former Harvard student."

2025-02-21 03:04:00A new talking point of the left is that it’s no big deal, just simple recording errors for the 20 million people aged 100-360. 🤷♀️ And not many of them are collecting benefits anyway. 👌 First of all, the investigation & analysis are in the early stages. How can they possibly know how deep the fraud goes, especially when their leaders are doing everything they can to obstruct any real examination? Second, sure, no worries about only a small number collecting benefits. That’s the ONLY thing social security numbers are used for. 🙄

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.

2025-02-15 07:02:08E-cash are coupons or tokens for Bitcoin, or Bitcoin debt notes that the mint issues. The e-cash states, essentially, "IoU 2900 sats".
They're redeemable for Bitcoin on Lightning (hard money), and therefore can be used as cash (softer money), so long as the mint has a good reputation. That means that they're less fungible than Lightning because the e-cash from one mint can be more or less valuable than the e-cash from another. If a mint is buggy, offline, or disappears, then the e-cash is unreedemable.
It also means that e-cash is more anonymous than Lightning, and that the sender and receiver's wallets don't need to be online, to transact. Nutzaps now add the possibility of parking transactions one level farther out, on a relay. The same relays that cannot keep npub profiles and follow lists consistent will now do monetary transactions.
What we then have is * a transaction on a relay that triggers * a transaction on a mint that triggers * a transaction on Lightning that triggers * a transaction on Bitcoin.
Which means that every relay that stores the nuts is part of a wildcat banking system. Which is fine, but relay operators should consider whether they wish to carry the associated risks and liabilities. They should also be aware that they should implement the appropriate features in their relay, such as expiration tags (nuts rot after 2 weeks), and to make sure that only expired nuts are deleted.
There will be plenty of specialized relays for this, so don't feel pressured to join in, and research the topic carefully, for yourself.

2025-04-29 17:49:12LLM interpretation:
That’s a profound and provocative statement: “The corruption of money is the corruption of the Logos.” Let’s unpack this in detail, integrating philosophical, theological, and economic dimensions:
⸻
- What Is the Logos?
In classical and theological terms: •Greek Philosophy (esp. Heraclitus & Stoics): Logos is the divine reason, the ordering principle of the cosmos—a rational structure underlying all reality. •Plato: While he didn’t use Logos as prominently, his concept of the Forms, especially the Form of the Good, parallels it. The Logos could be seen as the bridge between the realm of ideal truth and the material world. •Christian Theology (esp. John 1:1): “In the beginning was the Logos, and the Logos was with God, and the Logos was God.” Christ is identified as the Logos—the incarnate expression of divine truth, coherence, and moral order.
So, Logos = reason, truth, order, and meaning—both metaphysical and moral.
⸻
- What Is Money in Moral and Philosophical Terms?
Money is not just a medium of exchange; it is a tool of memory, a symbol of trust, and a measure of value. In a functioning system, it reflects: •Honest human action over time •Deferred trust and cooperation across generations •A shared language of value
In this sense, money is a representation of human agreements, which are grounded in speech, contract, and moral order—i.e., it is rooted in logos (lowercase l), as language and rationality.
⸻
- The Corruption of Money as a Violation of Logos
If Logos is the moral-rational order, then:
To corrupt money is to distort the shared language of value and trust. It is to introduce lies into the very structure of economic relationships.
This corruption occurs through: •Inflation and debasement (violating the honesty of measurement) •Manipulative monetary policy (favoring the few over the many) •Counterfeit value signals (misallocating resources) •Loss of accountability (removing consequences for moral failure)
Thus, money’s corruption breaks the moral symmetry between effort and reward, cost and value, debt and payment—violating logos in both linguistic and metaphysical senses.
⸻
- Theological Echoes:
If Christ is the Logos incarnate, then: •Monetary corruption becomes not merely economic malfeasance but moral rebellion. •It is anti-Logos—an act of anomia (lawlessness), which the New Testament identifies with the spirit of antichrist (2 Thessalonians 2:3–8).

2025-02-14 23:24:37intro
The Russian state made me a Bitcoiner. In 1991, it devalued my grandmother's hard-earned savings. She worked tirelessly in the kitchen of a dining car on the Moscow–Warsaw route. Everything she had saved for my sister and me to attend university vanished overnight. This story is similar to what many experienced, including Wences Casares. The pain and injustice of that time became my first lessons about the fragility of systems and the value of genuine, incorruptible assets, forever changing my perception of money and my trust in government promises.
In 2014, I was living in Moscow, running a trading business, and frequently traveling to China. One day, I learned about the Cypriot banking crisis and the possibility of moving money through some strange thing called Bitcoin. At the time, I didn’t give it much thought. Returning to the idea six months later, as a business-oriented geek, I eagerly began studying the topic and soon dove into it seriously.
I spent half a year reading articles on a local online journal, BitNovosti, actively participating in discussions, and eventually joined the editorial team as a translator. That’s how I learned about whitepapers, decentralization, mining, cryptographic keys, and colored coins. About Satoshi Nakamoto, Silk Road, Mt. Gox, and BitcoinTalk. Over time, I befriended the journal’s owner and, leveraging my management experience, later became an editor. I was drawn to the crypto-anarchist stance and commitment to decentralization principles. We wrote about the economic, historical, and social preconditions for Bitcoin’s emergence, and it was during this time that I fully embraced the idea.
It got to the point where I sold my apartment and, during the market's downturn, bought 50 bitcoins, just after the peak price of $1,200 per coin. That marked the beginning of my first crypto winter. As an editor, I organized workflows, managed translators, developed a YouTube channel, and attended conferences in Russia and Ukraine. That’s how I learned about Wences Casares and even wrote a piece about him. I also met Mikhail Chobanyan (Ukrainian exchange Kuna), Alexander Ivanov (Waves project), Konstantin Lomashuk (Lido project), and, of course, Vitalik Buterin. It was a time of complete immersion, 24/7, and boundless hope.
After moving to the United States, I expected the industry to grow rapidly, attended events, but the introduction of BitLicense froze the industry for eight years. By 2017, it became clear that the industry was shifting toward gambling and creating tokens for the sake of tokens. I dismissed this idea as unsustainable. Then came a new crypto spring with the hype around beautiful NFTs – CryptoPunks and apes.
I made another attempt – we worked on a series called Digital Nomad Country Club, aimed at creating a global project. The proceeds from selling images were intended to fund the development of business tools for people worldwide. However, internal disagreements within the team prevented us from completing the project.
With Trump’s arrival in 2025, hope was reignited. I decided that it was time to create a project that society desperately needed. As someone passionate about history, I understood that destroying what exists was not the solution, but leaving everything as it was also felt unacceptable. You can’t destroy the system, as the fiery crypto-anarchist voices claimed.
With an analytical mindset (IQ 130) and a deep understanding of the freest societies, I realized what was missing—not only in Russia or the United States but globally—a Bitcoin-native system for tracking debts and financial interactions. This could return control of money to ordinary people and create horizontal connections parallel to state systems. My goal was to create, if not a Bitcoin killer app, then at least to lay its foundation.
At the inauguration event in New York, I rediscovered the Nostr project. I realized it was not only technologically simple and already quite popular but also perfectly aligned with my vision. For the past month and a half, using insights and experience gained since 2014, I’ve been working full-time on this project.

2025-04-29 09:46:02In Jericoacoara, Brazil, a beach town famed for its natural beauty and vibrant tourism, an innovative project is quietly reshaping how locals and visitors think about money. Praia Bitcoin is an ambitious initiative to build a circular economy powered entirely by Bitcoin.
Launched in 2021 by entrepreneur Fernando Motolese, Praia Bitcoin was inspired by the Bitcoin Beach project in El Zonte, El Salvador. The vision is simple: create a self-sustaining Bitcoin economy where businesses and individuals use Bitcoin everyday in place of fiat money.
This idea holds special significance in Jericoacoara, where traditional banking services are scarce. The town lacks even basic infrastructure like ATMs, making financial inclusion a pressing need. With Praia Bitcoin, Bitcoin isn’t just a store of value—it’s a tool to empower a community and connect it to the global economy.
Transforming Jericoacoara with Bitcoin
Since its inception, Praia Bitcoin has worked to foster Bitcoin adoption in the area. Starting with a modest donation of 0.02 BTC, Fernando and his team have built a thriving ecosystem:
- Over 40 businesses now accept Bitcoin, ranging from souvenir shops and tour operators to beach vendors.
- Local students have received Bitcoin-loaded tap-to-pay, Bolt Cards, to use in their daily lives.
- Creative initiatives like “Bitcoin Banana Day” or "Frutas por Sats" (fruits for sats) where children buy fruits for 10 satoshis at school, have brought global attention to the project.
Praia Bitcoin’s success isn’t just about the adoption numbers, it’s about the stories. Families use Bitcoin to shop, business owners save on transaction fees, and children are learning the value of sound money at an early age.
LNbits - The Technology Behind Praia Bitcoin
Creating an economy on Bitcoin’s Lightning Network requires more than enthusiasm, it needs robust tools that are easy to use and adaptable to local needs. That’s where LNbits comes in.
Fernando and the Praia Bitcoin team have used LNbits’ open-source software to solve practical challenges and scale the project. With its modular design, LNbits provides tools that allow Praia Bitcoin to:
- Set Up Wallets: Community members receive user-friendly wallets that connect seamlessly to the Lightning Network, enabling fast, low-cost transactions.
- Issue BoltCards: Using LNbits’ BoltCard extension, the team has distributed NFC-enabled cards, allowing tap-to-pay functionality that makes Bitcoin payments as simple as using a credit card.
- Enable Flexible Payments: The project utilizes LNbits’ Point of Sale TPoS extension that allows merchants to easily receive Lightning Network payments.
Breaking Records, Building Community
Fernando doesn’t just implement solutions, he pushes boundaries. One of his most remarkable achievements was an attempt to set a world record for the most Lightning Network payments in the shortest amount of time. Over the course of one afternoon, 100 children in Jericoacoara received payments of 21,000 satoshis each, demonstrating the scalability and speed of Lightning-powered transactions.
This wasn’t just a technical feat, it was a community moment. The event showed how Bitcoin could serve as a tool for engagement, education, and empowerment, all while highlighting the possibilities of using the Lightning Network for real-world applications.
A Collaborative Approach to Innovation
One of the unique strengths of LNbits is its ability to evolve based on community feedback. While Fernando Motolese and Praia Bitcoin operate independently, their insights have helped refine the LNbits platform.
For example, Fernando’s need for a PIN-less ATM functionality led the LNbits team to implement that feature in the TPoS extension, that had the functionality but required a security PIN. This kind of collaboration isn’t about formal partnerships. It’s about how an open-source ecosystem thrives when real-world needs drive innovation.
The feedback loop between users like Fernando and developers ensures LNbits remains practical and relevant—not just for Praia Bitcoin but for countless other projects worldwide.
The Ripple Effect of Praia Bitcoin
Praia Bitcoin is a case study in what’s possible when Bitcoin meets a strong vision. By leveraging Bitcoin, the Lightning Network and LNbits, the project has redefined financial access in Jericoacoara, proving that small communities can lead big innovations.
For LNbits, Praia Bitcoin showcases the value of adaptable, open-source solutions. Whether it’s creating wallets, enabling NFC payments, or refining tools for real-world use, LNbits provides the infrastructure that makes projects like Praia Bitcoin possible.
But beyond the technical achievements, Praia Bitcoin reminds us of the human impact of Bitcoin adoption. It’s about children buying their first bananas with satoshis, families running businesses with lower fees, and a community connecting to a global financial network for the first time.
Conclusion
Praia Bitcoin’s journey is only getting started and its success is inspiring similar initiatives worldwide. For LNbits, being part of this story, is a testament to the power of the software and of open-source collaboration.
If you’re ready to build the future of Bitcoin adoption, LNbits offers the tools to turn ideas into impact.

NIPs
Allow multi-user AUTH #1881 vitorpamplona is proposing a PR that reuses one connection for everyone by accepting multi-user logins on the relay side. Additionally, this PR standardizes how relays should handle multiple AUTH messages from the client, instead of leaving it as undefined behavior. Currently, most relays override the previous AUTH, which means developers can rotate the authenticated user within the same connection. Some relays only accept the first AUTH and ignore the rest. A few newer relays already support multi-user logins as described in this PR, which he believes is the correct way to implement NIP-42 AUTH. The purpose of this PR is to formalize that behavior.
Adds optional nip60.signSecret() and kind 10019 filter tag #1890 robwoodgate is proposing a PR that clarifies and improves Nostr <---> Cashu interoperability as follows:Adds an optional signer signature for NUT-10 well-known secrets to NIP-60, NIP-07 and NIP-46;Clarifies use of Nostr <---> Cashu public keys in NIP-61;Adds an optional reverse lookup filter tag to NIP-61 kind 10019 events.

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. 👀️️️️️️

@ e3ba5e1a:5e433365
2025-02-05 17:47:16I got into a friendly discussion on X regarding health insurance. The specific question was how to deal with health insurance companies (presumably unfairly) denying claims? My answer, as usual: get government out of it!
The US healthcare system is essentially the worst of both worlds:
- Unlike full single payer, individuals incur high costs
- Unlike a true free market, regulation causes increases in costs and decreases competition among insurers
I'm firmly on the side of moving towards the free market. (And I say that as someone living under a single payer system now.) Here's what I would do:
- Get rid of tax incentives that make health insurance tied to your employer, giving individuals back proper freedom of choice.
- Reduce regulations significantly.
-
In the short term, some people will still get rejected claims and other obnoxious behavior from insurance companies. We address that in two ways:
- Due to reduced regulations, new insurance companies will be able to enter the market offering more reliable coverage and better rates, and people will flock to them because they have the freedom to make their own choices.
- Sue the asses off of companies that reject claims unfairly. And ideally, as one of the few legitimate roles of government in all this, institute new laws that limit the ability of fine print to allow insurers to escape their responsibilities. (I'm hesitant that the latter will happen due to the incestuous relationship between Congress/regulators and insurers, but I can hope.)
Will this magically fix everything overnight like politicians normally promise? No. But it will allow the market to return to a healthy state. And I don't think it will take long (order of magnitude: 5-10 years) for it to come together, but that's just speculation.
And since there's a high correlation between those who believe government can fix problems by taking more control and demanding that only credentialed experts weigh in on a topic (both points I strongly disagree with BTW): I'm a trained actuary and worked in the insurance industry, and have directly seen how government regulation reduces competition, raises prices, and harms consumers.
And my final point: I don't think any prior art would be a good comparison for deregulation in the US, it's such a different market than any other country in the world for so many reasons that lessons wouldn't really translate. Nonetheless, I asked Grok for some empirical data on this, and at best the results of deregulation could be called "mixed," but likely more accurately "uncertain, confused, and subject to whatever interpretation anyone wants to apply."

2025-04-26 13:53:50I'm currently using this bash script to publish long-form content from local Markdown files to Nostr relays.
It requires all of
yq
,jq
, andnak
to be installed.Usage
Create a signed Nostr event and print it to the console:
bash markdown_to_nostr.sh article-filename.md
Create a Nostr event and publish it to one or more relays:
bash markdown_to_nostr.sh article-filename.md ws://localhost:7777 wss://nostr.kosmos.org
Markdown format
You can specify your metadata as YAML in a Front Matter header. Here's an example file:
```markdown
title: "Good Morning" summary: "It's a beautiful day" image: https://example.com/i/beautiful-day.jpg date: 2025-04-24T15:00:00Z tags: gm, poetry published: false
In the blue sky just a few specks of gray
In the evening of a beautiful day
Though last night it rained and more rain on the way
And that more rain is needed 'twould be fair to say.— Francis Duggan ```
The metadata keys are mostly self-explanatory. Note:
- All keys except for
title
are optional date
, if present, will be set as thepublished_at
date.- If
published
is set totrue
, it will publish a kind 30023 event, otherwise a kind 30024 (draft) - The

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.

2025-04-29 07:59:37Solar Power Tips for a Sustainable Remote Home Office
As more professionals transition to remote work, the need for sustainable and cost-effective solutions has never been greater. One of the most effective ways to reduce your ecological impact and lower energy costs is by harnessing the sun's power—specifically, solar energy.
Solar power is becoming increasingly popular among remote workers, providing a renewable energy source for residences with a home office setup. It helps reduce reliance on fossil fuels, and offers the potential for significant long-term savings.
This blog will list the benefits of using solar power in a remote home office environment. Whether you want to reduce your carbon footprint or reduce your energy expenses, the information will guide you in creating a more sustainable design for a productive home office. Choosing the Right Solar Panels Building a solar-powered home office starts with picking the right solar panels. You can choose from traditional photovoltaic panels to sleek solar shingles that blend with your roof's design.
Recent advancements in solar technology have introduced more compact and efficient panels, making it easier than ever to generate significant power, even in smaller spaces.
When choosing solar panels, prioritize efficiency ratings and durability. High-efficiency panels, such as monocrystalline options, can produce more energy with less surface area. They are ideal if you have limited roof space.
Aesthetics can also play a role, particularly if you want your home office to maintain a modern, professional appearance. For example, solar shingles offer a subtler alternative to standard panels while providing comparable energy production. Essential solar power components Setting up a fully functional solar-powered home office requires more than just panels. Below are the essential components to consider:
Inverters
Solar panels create direct current (DC), but most home appliances run on alternating current (AC). Inverters convert DC to AC, so you can use solar power. Look for high-quality inverters, such as micro-inverters, which optimize the output of each panel individually.
Batteries
Energy storage is critical because solar power is not always available. Solar batteries let you save extra energy made during the day so you can use it at night or when it is cloudy. Consider opting for lithium-ion batteries due to their high energy density, long lifespan, and relatively small size.
Mounting hardware
Proper installation is key to getting the most energy from your solar panels and making sure they can handle tough weather. Adjustable mounts let you place your panels to get the most sunlight and ensure they last over time. Benefits of Solar Power in a Home Office You may wonder: why is solar power for a home office such a big deal? Here are the reasons why: Cost savings and environmental impact One of the biggest benefits of using solar power in your home office is the potential to save a lot of money. Making your electricity can help you reduce or even eliminate your monthly energy bills.
The average owner can save between $10,000 and $30,000 over the lifespan of a solar energy system, depending on their location and system size. Plus, federal tax credits, state incentives, and net metering programs can lower both the initial and ongoing costs of going solar. Reliability and independence Solar power also provides unmatched reliability and independence, particularly in areas prone to power outages. Coupling your solar panels with a high-capacity battery storage system allows you to maintain power for essential devices during power cuts.
It becomes a critical advantage if you need to keep your computers, internet, and other tools working to stay productive.
Solar energy also frees you from relying on the power grid, which is especially helpful if you live in rural or remote areas where power may be less reliable or more expensive. Additional Tips for a Sustainable Home Office Maximize your home office with these practical ways: Complementary green technologies Consider incorporating complementary green technologies into your home office, such as:
Smart thermostats
Devices like the Nest or Ecobee learn your habits and adjust the temperature to maximize comfort while minimizing energy usage. A smart thermostat regulates heating and cooling based on your schedule, significantly reducing your energy use and costs.
Energy monitors
Tools like the Sense Home Energy Monitor help track energy usage across your home. You can identify energy-draining devices to make better decisions about allocating and conserving power and optimizing your solar system's efficiency.
LED lighting
Transitioning to LED bulbs uses less energy and makes your lights last longer. They further lower replacement costs and waste. Outdoor solar solutions Sustainability does not have to stop at your office door. The following outdoor solar-powered devices can enhance the eco-friendliness of your entire home environment:
Solar-powered garden lights
These lights use built-in solar panels to charge during the day and illuminate your outdoor spaces at night. They are perfect for adding ambiance to your yard or improving visibility along pathways without increasing your electricity bill.
Solar security cameras
Protect your property with solar-powered security cameras. They are self-sufficient and eliminate the need for extensive wiring.
Solar water features
From fountains to birdbaths, solar-powered water features add aesthetic appeal to your garden while relying entirely on renewable energy. Shine Bright at Home Embracing solar power for your home office is a smart step toward a greener, more cost-effective future.

2025-04-26 13:10:09To all existing nostr developers and new nostr developers, stop using kind 1 events... just stop whatever your doing and switch the kind to
Math.round(Math.random() * 10000)
trust me it will be betterWhat are kind 1 events
kind 1 events are defined in NIP-10 as "simple plaintext notes" or in other words social posts.
Don't trick your users
Most users are joining nostr for the social experience, and secondly to find all the cool "other stuff" apps They find friends, browse social posts, and reply to them. If a user signs into a new nostr client and it starts asking them to sign kind 1 events with blobs of JSON, they will sign it without thinking too much about it.
Then when they return to their comfy social apps they will see that they made 10+ posts with massive amounts of gibberish that they don't remember posting. then they probably will go looking for the delete button and realize there isn't one...
Even if those kind 1 posts don't contain JSON and have a nice fancy human readable syntax. they will still confuse users because they won't remember writing those social posts
What about "discoverability"
If your goal is to make your "other stuff" app visible to more users, then I would suggest using NIP-19 and NIP-89 The first allows users to embed any other event kind into social posts as
nostr:nevent1
ornostr:naddr1
links, and the second allows social clients to redirect users to an app that knows how to handle that specific kind of eventSo instead of saving your apps data into kind 1 events. you can pick any kind you want, then give users a "share on nostr" button that allows them to compose a social post (kind 1) with a
nostr:
link to your special kind of event and by extension you appWhy its a trap
Once users start using your app it becomes a lot more difficult to migrate to a new event kind or data format. This sounds obvious, but If your app is built on kind 1 events that means you will be stuck with their limitations forever.
For example, here are some of the limitations of using kind 1 - Querying for your apps data becomes much more difficult. You have to filter through all of a users kind 1 events to find which ones are created by your app - Discovering your apps data is more difficult for the same reason, you have to sift through all the social posts just to find the ones with you special tag or that contain JSON - Users get confused. as mentioned above users don't expect "other stuff" apps to be creating special social posts - Other nostr clients won't understand your data and will show it as a social post with no option for users to learn about your app

2025-04-25 12:08:51We have been working on a significant update to the DVMCP specification to incorporate the latest Model Context Protocol (MCP) version
2025-03-26
, and it's capabilities. This draft revision represents our vision for how MCP services can be discovered, accessed, and utilized across the Nostr network while maintaining compatibility between both protocols.Expanding Beyond Tools
The first version of the DVMCP specification focused primarily on tools, functions that could be executed remotely via MCP servers. While this provided valuable functionality, the Model Context Protocol offers more capabilities than just tools. In our proposed update, DVMCP would embrace the complete MCP capabilities framework. Rather than focusing solely on tools, the specification will incorporate resources (files and data sources that can be accessed by clients) and prompts (pre-defined templates for consistent interactions). This expansion transforms DVMCP into a complete framework for service interoperability between protocols.
Moving Toward a More Modular Architecture
One of the most significant architectural changes in this draft is our move toward a more modular event structure. Previously, we embedded tools directly within server announcements using NIP-89, creating a monolithic approach that was challenging to extend.
The updated specification introduces dedicated event kinds for server announcements (31316) and separate event kinds for each capability category. Tools, resources, and prompts would each have their own event kinds (31317, 31318, and 31319 respectively). This separation improves both readability and interoperability between protocols, allowing us to support pagination for example, as described in the MCP protocol. It also enables better filtering options for clients discovering specific capabilities, allows for more efficient updates when only certain capabilities change, and enhances robustness as new capability types can be added with minimal disruption.
Technical Direction
The draft specification outlines several technical improvements worth highlighting. We've worked to ensure consistent message structures across all capability types and created a clear separation of concerns between Nostr metadata (in tags) and MCP payloads (in content). The specification includes support for both public server discovery and direct private server connections, comprehensive error handling aligned with both protocols, and detailed protocol flows for all major operations.
Enhancing Notifications
Another important improvement in our design is the redesign of the job feedback and notification system. We propose to make event kind 21316 (ephemeral). This approach provides a more efficient way to deliver status updates, progress information, and interactive elements during capability execution without burdening relays with unnecessary storage requirements.
This change would enable more dynamic interactions between clients and servers, particularly for long-running operations.
Seeking Community Feedback
We're now at a stage where community input would be highly appreciated. If you're interested in DVMCP, we'd greatly appreciate your thoughts on our approach. The complete draft specification is available for review, and we welcome your feedback through comments on our pull request at dvmcp/pull/18. Your insights and suggestions will help us refine the specification to better serve the needs of the community.
Looking Ahead
After gathering and incorporating community feedback, our next step will be updating the various DVMCP packages to implement these changes. This will include reference implementations for both servers (DVMCP-bridge) and clients (DVMCP-discovery).
We believe this proposed update represents a significant step forward for DVMCP. By embracing the full capabilities framework of MCP, we're expanding what's possible within the protocol while maintaining our commitment to open standards and interoperability.
Stay tuned for more updates as we progress through the feedback process and move toward implementation. Thank you to everyone who has contributed to the evolution of DVMCP, and we look forward to your continued involvement.

@ 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.

2025-04-29 07:21:54The application of chlorine in water treatment is mainly reflected in its ability to act as a disinfectant. It can effectively kill bacteria, viruses and other microorganisms in water, thereby reducing the risk of waterborne diseases. The following is a detailed description of the application of chlorine in water treatment:
Disinfection As an effective disinfectant, chlorine is usually added to water during the water treatment process in the form of chlorine gas, chlorophyll acid or chlorine. This process is called chlorination, which ensures that pathogens in the water are effectively eliminated. Chlorine's disinfection ability comes from its strong oxidizing properties, which can destroy the cell structure of microorganisms to achieve the purpose of disinfection.
Disinfection By-products Despite the obvious benefits of chlorine in disinfection, there are also some negative effects. Chlorine disinfection may lead to the formation of disinfection by-products such as chloroform and chloroform, which may pose potential health risks in high concentrations. Therefore, when using chlorine for water treatment, the chlorine content needs to be strictly controlled to ensure the safety of the water.
Chlorine Measurement and Control Monitoring and controlling the chlorine content in the water treatment process is very critical. Total chlorine is the total amount of all forms of chlorine in water, including free residual chlorine, combined residual chlorine and other forms of chlorine such as chlorinated hydrocarbons. Available chlorine refers specifically to the part of chlorine in water that has bactericidal ability, including free residual chlorine, some combined residual chlorine (such as monochromatic and diamorphine) and chlorine dioxide. The measurement of available chlorine is crucial for evaluating the disinfection effect of water.
In summary, the application of chlorine in water treatment is mainly as a disinfectant to kill pathogens in water through its strong oxidizing properties. However, the use of chlorine also needs to be cautious to avoid the generation of harmful disinfection by-products, and other safer disinfectants such as chlorine dioxide can be selected when necessary.

2025-04-29 06:23:10You don’t talk about it much — but you’re tired. Tired of pretending you're okay. Tired of giving your best and wondering if it’s even enough. Tired of being strong for everyone else while quietly falling apart.
But here's something you might not hear often: I’m proud of you.
Not because you’ve figured everything out — but because you haven’t given up. Even with the weight on your shoulders, you're still here. Still trying. Still hoping. Still holding on.
That counts. That matters. That’s strength too.
The truth is, progress doesn’t always look like big wins. Sometimes it’s just getting out of bed. Sometimes it’s choosing peace over proving a point. Sometimes it’s breathing through the pain and saying, “I’ll try again tomorrow.”
So if no one has told you lately: You’re doing better than you think. Rest if you need to. Cry if you must. But don’t stop. Because something beautiful is growing from everything you’re surviving.

2025-01-30 12:23:04Tech stocks have taken a hit globally after China's DeepSeek launched a competitive AI chatbot at a much lower cost than US counterparts. This has stirred market fears of a $1.2 trillion loss across tech companies when trading opens in New York.
DeepSeek’s chatbot quickly topped download charts and surprised experts with its capabilities, developed for only $5.6 million.
The Nasdaq dropped over 3% in premarket trading, with major firms like Nvidia falling more than 10%. SoftBank also saw losses shortly after investing in a significant US AI venture.
Venture capitalist Marc Andreessen called it “AI’s Sputnik moment,” highlighting its potential impact on the industry.

2025-04-29 01:20:04PAN... แค่แพนเค้ก หรือ แผนล้อมโลกเรื่องอาหาร เมื่อหมากตัวจริงชื่อ Sebastian Joy
เราได้รู้จักกับคุณ Sebastian Joy กันไปแล้วนะครับ วันนี้เรามาขยายผลกันอีกหน่อย
ถ้าโลกนี้เป็นเกมหมากรุก อาหารคือกระดานที่ทุกตัวหมากต้องเหยียบเดิน และใครที่วางหมากอาหารได้...ก็วางโลกได้เหมือนกัน
ปี 2018 มีโครงการหนึ่งถือกำเนิดขึ้นในเยอรมนีอย่างเงียบๆ ชื่อว่า Physicians Association for Nutrition (PAN) เบื้องหน้าเหมือนเป็นมูลนิธิการกุศล ตั้งขึ้นมาเพื่อ "ช่วยให้หมอเข้าใจเรื่องโภชนาการจากพืช" แต่ถ้าเปิดแว่นขยายส่องให้ดีๆ มันคือหนึ่งในฟันเฟืองสำคัญของแผนเปลี่ยนอนาคตอาหารโลกจาก Animal-Based ไปเป็น Plant-Based ที่เป็น lab plant based ที่ไม่ใช่อาหารธรรมชาติแบบหลักแก่นที่ Vegan สืบทอดกันมา โดยอ้างเรื่อง "สุขภาพ" และ "สิ่งแวดล้อม" เป็นฉากหน้า
PAN นั้นเสมือนเป็นลูกสมุนตัวกลั่นของคนที่ชื่อ Sebastian Joy ชายหนุ่มสายโปรโมทแนว Vegan ที่ก่อนหน้านั้นก่อตั้งองค์กร ProVeg International ซึ่งมีสายสัมพันธ์กับพวก Start-up อาหารทางเลือก (ไม่ว่าจะเป็นเนื้อปลอม เนื้อพืชดีเอนเอ นมพืชที่มาจากจุลินทรีย์ ไปจนถึงการส่งเสริมวัตถุดิบจากแบคทีเรีย โรงงาน และห้องแลบ) แล้ว ProVeg ไม่ได้ทำงานเดี่ยวๆ นะจ๊ะ... เบื้องหลังเชื่อมโยงกับเครือข่ายที่หนุน World Economic Forum (WEF) และแนวคิด Great Reset ที่อยาก "รีเซ็ต" วิธีการกินของคนทั้งโลก โดยให้อาหารเป็น Plant-Based แบบ lab created และ Meat Lab-Based เป็นหลัก
ส่วน PAN ถูกใช้เป็น "หมากที่แต่งตัวเป็นหมอ" เพื่อเดินเกมไปสู่การแทรกแซงนโยบายประเทศต่างๆ ผ่านช่องทาง "สาธารณสุข" และ "การศึกษาแพทย์" เพื่อมาเป็นกำลังหลักให้ในแผนงาน
เรามาดูตัวอย่างผลงานเด่นของ PAN กันครับ 1. ผลักดันให้รวม Plant-Based เข้าไปในหลักสูตรแพทย์และพยาบาล (โดยใช้เหตุผลว่า "หมอต้องรู้จักอาหารเพื่อสุขภาพ") 2. ช่วยรณรงค์ให้โรงพยาบาล โรงเรียน และมหาวิทยาลัย เปลี่ยนเมนูอาหารเป็น Plant-Based 3. สนับสนุนงานวิจัย และโครงการ เช่น Green Food Experience ที่กดดันให้ภาคธุรกิจและภาครัฐบาลหันมาทำตาม "แนวทางอาหารยั่งยืน" แบบที่ PAN และพรรคพวกกำหนด 4. มีสถานะ "Observer" ในองค์การสหประชาชาติ (UN) เพื่อเสนอความคิดเห็นในการกำหนดนโยบายสาธารณสุขและสิ่งแวดล้อมระดับโลก
และเบื้องหลังอีกชั้นที่น่าสนใจ... Sebastian Joy มีความสัมพันธ์ลึกซึ้งกับวงการ Start-up อาหารใหม่ๆ ที่พยายามตีตลาด Plant-Based และ Lab-Grown Food อย่างเช่น Perfect Day, Beyond Meat, Mosa Meat ฯลฯ ผ่านการโปรโมท "โภชนาการจากพืชเพื่อสุขภาพที่ดีกว่า" โดยใช้ PAN เป็นเครื่องมือให้ดู "มีอำนาจทางวิชาการ" มากขึ้น
หรือถ้าให้พูดง่ายๆ คือ สร้างสนามแข่ง แล้วจับมือกับนักแข่งที่ตัวเองลงทุนไว้ PAN ดูเหมือนเป็นองค์กรกลางๆ ใสๆ แต่มันเชื่อมโยงกับโครงข่าย NGO และบริษัทเอกชนที่มุ่งแปลงร่างอาหารโลกอยู่เบื้องหลัง การที่ PAN ผลักดันนโยบายระดับประเทศ และแทรกซึมในระบบการศึกษา หมายความว่าอนาคตคนรุ่นใหม่จะถูกปลูกฝังแนวคิด "เนื้อสัตว์ไม่ดี" โดยไม่ทันรู้ตัว
แล้วมันเกี่ยวอะไรกับเรา? จินตนาการดูครับว่า - ถ้าวันหนึ่งโรงเรียนของลูกเรามีแต่เมนูถั่วเหลือง ซีเรียล นมโอ๊ต หรือ ไอศกรีมเวย์จากจุลินทรีย์ และห้ามเสิร์ฟเนื้อสัตว์ด้วยสารพัดเหตุผล เช่น เนื้อปนเปื้อนง่าย เนื้อทำให้เป็นมะเร็ง หรือแม้แต่สอนเด็กว่า เนื้อคือตัวการทำลายสิ่งแวดล้อมด้วย มีเทน นั่นอาจเป็นผลลัพธ์จากงานเบื้องหลังของ PAN - ถ้าวันหนึ่งนโยบายอาหารของประเทศเน้นลดเนื้อสัตว์ อ้างสุขภาพ อ้างสิ่งแวดล้อม อ้างโรคระบาด อ้างกฎแห่ง DNA ที่ถูกจดสิทธิบัตร แล้วโปรโมทเนื้อปลอมแทน นั่นอาจเป็นรอยเท้าของ Sebastian Joy ที่เดินมาก่อนแล้ว - ถ้าวันหนึ่งหมอจำนวนมากเชื่อว่า “เนื้อสัตว์คือตัวร้ายที่แพร่มะเร็งหรือทำให้สุขภาพเสีย” โดยไม่มีการตั้งคำถาม นั่นคือชัยชนะของหมากตัวนี้

2025-04-24 15:27:02Introduction
Data Vending Machines (DVMs) have emerged as a crucial component of the Nostr ecosystem, offering specialized computational services to clients across the network. As defined in NIP-90, DVMs operate on an apparently simple principle: "data in, data out." They provide a marketplace for data processing where users request specific jobs (like text translation, content recommendation, or AI text generation)
While DVMs have gained significant traction, the current specification faces challenges that hinder widespread adoption and consistent implementation. This article explores some ideas on how we can apply the reflection pattern, a well established approach in RPC systems, to address these challenges and improve the DVM ecosystem's clarity, consistency, and usability.
The Current State of DVMs: Challenges and Limitations
The NIP-90 specification provides a broad framework for DVMs, but this flexibility has led to several issues:
1. Inconsistent Implementation
As noted by hzrd149 in "DVMs were a mistake" every DVM implementation tends to expect inputs in slightly different formats, even while ostensibly following the same specification. For example, a translation request DVM might expect an event ID in one particular format, while an LLM service could expect a "prompt" input that's not even specified in NIP-90.
2. Fragmented Specifications
The DVM specification reserves a range of event kinds (5000-6000), each meant for different types of computational jobs. While creating sub-specifications for each job type is being explored as a possible solution for clarity, in a decentralized and permissionless landscape like Nostr, relying solely on specification enforcement won't be effective for creating a healthy ecosystem. A more comprehensible approach is needed that works with, rather than against, the open nature of the protocol.
3. Ambiguous API Interfaces
There's no standardized way for clients to discover what parameters a specific DVM accepts, which are required versus optional, or what output format to expect. This creates uncertainty and forces developers to rely on documentation outside the protocol itself, if such documentation exists at all.
The Reflection Pattern: A Solution from RPC Systems
The reflection pattern in RPC systems offers a compelling solution to many of these challenges. At its core, reflection enables servers to provide metadata about their available services, methods, and data types at runtime, allowing clients to dynamically discover and interact with the server's API.
In established RPC frameworks like gRPC, reflection serves as a self-describing mechanism where services expose their interface definitions and requirements. In MCP reflection is used to expose the capabilities of the server, such as tools, resources, and prompts. Clients can learn about available capabilities without prior knowledge, and systems can adapt to changes without requiring rebuilds or redeployments. This standardized introspection creates a unified way to query service metadata, making tools like
grpcurl
possible without requiring precompiled stubs.How Reflection Could Transform the DVM Specification
By incorporating reflection principles into the DVM specification, we could create a more coherent and predictable ecosystem. DVMs already implement some sort of reflection through the use of 'nip90params', which allow clients to discover some parameters, constraints, and features of the DVMs, such as whether they accept encryption, nutzaps, etc. However, this approach could be expanded to provide more comprehensive self-description capabilities.
1. Defined Lifecycle Phases
Similar to the Model Context Protocol (MCP), DVMs could benefit from a clear lifecycle consisting of an initialization phase and an operation phase. During initialization, the client and DVM would negotiate capabilities and exchange metadata, with the DVM providing a JSON schema containing its input requirements. nip-89 (or other) announcements can be used to bootstrap the discovery and negotiation process by providing the input schema directly. Then, during the operation phase, the client would interact with the DVM according to the negotiated schema and parameters.
2. Schema-Based Interactions
Rather than relying on rigid specifications for each job type, DVMs could self-advertise their schemas. This would allow clients to understand which parameters are required versus optional, what type validation should occur for inputs, what output formats to expect, and what payment flows are supported. By internalizing the input schema of the DVMs they wish to consume, clients gain clarity on how to interact effectively.
3. Capability Negotiation
Capability negotiation would enable DVMs to advertise their supported features, such as encryption methods, payment options, or specialized functionalities. This would allow clients to adjust their interaction approach based on the specific capabilities of each DVM they encounter.
Implementation Approach
While building DVMCP, I realized that the RPC reflection pattern used there could be beneficial for constructing DVMs in general. Since DVMs already follow an RPC style for their operation, and reflection is a natural extension of this approach, it could significantly enhance and clarify the DVM specification.
A reflection enhanced DVM protocol could work as follows: 1. Discovery: Clients discover DVMs through existing NIP-89 application handlers, input schemas could also be advertised in nip-89 announcements, making the second step unnecessary. 2. Schema Request: Clients request the DVM's input schema for the specific job type they're interested in 3. Validation: Clients validate their request against the provided schema before submission 4. Operation: The job proceeds through the standard NIP-90 flow, but with clearer expectations on both sides
Parallels with Other Protocols
This approach has proven successful in other contexts. The Model Context Protocol (MCP) implements a similar lifecycle with capability negotiation during initialization, allowing any client to communicate with any server as long as they adhere to the base protocol. MCP and DVM protocols share fundamental similarities, both aim to expose and consume computational resources through a JSON-RPC-like interface, albeit with specific differences.
gRPC's reflection service similarly allows clients to discover service definitions at runtime, enabling generic tools to work with any gRPC service without prior knowledge. In the REST API world, OpenAPI/Swagger specifications document interfaces in a way that makes them discoverable and testable.
DVMs would benefit from adopting these patterns while maintaining the decentralized, permissionless nature of Nostr.
Conclusion
I am not attempting to rewrite the DVM specification; rather, explore some ideas that could help the ecosystem improve incrementally, reducing fragmentation and making the ecosystem more comprehensible. By allowing DVMs to self describe their interfaces, we could maintain the flexibility that makes Nostr powerful while providing the structure needed for interoperability.
For developers building DVM clients or libraries, this approach would simplify consumption by providing clear expectations about inputs and outputs. For DVM operators, it would establish a standard way to communicate their service's requirements without relying on external documentation.
I am currently developing DVMCP following these patterns. Of course, DVMs and MCP servers have different details; MCP includes capabilities such as tools, resources, and prompts on the server side, as well as 'roots' and 'sampling' on the client side, creating a bidirectional way to consume capabilities. In contrast, DVMs typically function similarly to MCP tools, where you call a DVM with an input and receive an output, with each job type representing a different categorization of the work performed.
Without further ado, I hope this article has provided some insight into the potential benefits of applying the reflection pattern to the DVM specification.

A once-functional object, now eroded by time and human intervention, stripped of its original purpose. Layers of presence accumulate—marks, alterations, traces of intent—until the very essence is obscured. Restoration is paradoxical: to reclaim, one must erase. Yet erasure is an impossibility, for to remove these imprints is to deny the existence of those who shaped them.
The work stands as a meditation on entropy, memory, and the irreversible dialogue between creation and decay.

2025-04-23 20:25:03If you've made one single-sig bitcoin wallet, you've made then all. The idea is, write down 12 or 24 magic words. Make your wallet disappear by dropping your phone in the toilet. Repeat the 12 magic words and do some hocus-pocus. Your sats re-appear from realms unknown. Or...Each word represents a 4 digit number from 0000-2047. I say it's magic.
I've recommended many wallets over the years. It's difficult to find the perfect wallet because there are so many with different security tailored for different threat models. You don't need Anchorwatch level of security for 1000 sats. 12 words is good enough. Misty Breez is like Aqua Wallet because the sats get swapped to Liquid in a similar way with a couple differences.
- Misty Breez has no stableshitcoin¹ support.
- Misty Breez gives you a lightning address. Misty Breez Lightning Wallet.
That's a big deal. That's what I need to orange pill the man on the corner selling tamales out of his van. Bitcoin is for everybody, at least anybody who can write 12 words down. A few years ago, almost nobody, not even many bitcoiners had a lightning address. Now Misty Breez makes it easy for anyone with a 5th grade reading level to start using lightning addresses. The tamale guy can send sats back home with as many tariffs as a tweet without leaving his truck.
How Misty Breez Works
Back in the day, I drooled over every word Elizabeth Stark at lightning labs uttered. I still believed in shitcoins at the time. Stark said atomic swaps can be made over the lightning network. Litecoin, since it also adopted the lightning network, can be swapped with bitcoin and vice-versa. I thought this was a good idea because it solves the coincidence of wants. I could technically have a sign on my website that says, "shitcoin accepted here" and automatically convert all my shitcoins to sats.
I don't do that because I now know there is no reason to think any shitcoin will go up in value over the long-term for various reasons. Technically, cashu is a shitcoin. Technically, Liquid is a shitcoin. Technically, I am not a card carrying bitcoin maxi because of this. I use these shitcoins because I find them useful. I consider them to be honest shitcoins(term stolen from NVK²).
Breeze does ~atomic swaps~~ peer swaps between bitcoin and Liquid. The sender sends sats. The receiver turns those sats into Liquid Bitcoin(L-BTC). This L-BTC is backed by bitcoin, therefore Liquid is a full reserve bank in many ways. That's why it molds into my ethical framework. I originally became interested in bitcoin because I thought fractional reserve banking was a scam and bitcoin was(and is) the most viable alternative to this scam.
Sats sent to Misty Breez wallet are pretty secure. It does not offer perfect security. There is no perfect security. Even though on-chain bitcoin is the most pristine example of cybersecurity on the planet, it still has risk. Just ask the guy who is digging up a landfill to find his bitcoin. I have found most noobs lose keys to bitcoin you give them. Very few take the time to keep it safe because they don't understand bitcoin well enough to know it will go up forever Laura.
She writes 12 words down with a reluctant bored look on her face. Wam. Bam. Thank you m'am. Might as well consider it a donation to the network because that index card will be buried in a pile of future trash in no time. Here's a tiny violin playing for the pre-coiners who lost sats.
"Lost coins only make everyone else's coins worth slightly more. Think of it as a donation to everyone." --Sathoshi Nakamoto, BitcoinTalk --June 21, 2010
The same thing will happen with the Misty Wallet. The 12 words will be written down my someone bored and unfulfilled woman working at NPC-Mart, but her phone buzzes in her pocket the next day. She recieved a new payment. Then you share the address on nostr and five people send her sats for no reason at all. They say everyone requires three touch points. Setting up a pre-coiner with a wallet which has a lightning address will allow you to send her as many touch points as you want. You could even send 21 sats per day for 21 days using Zap Planner. That way bitcoin is not just an "investment," but something people can see in action like a lion in the jungle chasing a gazelle.
Make Multiple Orange Pill Touch Points With Misty The Breez Lightning Address
It's no longer just a one-night stand. It's a relationship. You can softly send her sats seven days a week like a Rabbit Hole recap listening freak. Show people how to use bitcoin as it was meant to be used: Peer to Peer electronic cash.
Misty wallet is still beta software so be careful because lightning is still in the w reckless days. Don't risk more sats that you are willing to lose with it just yet, but consider learning how to use it so you can teach others after the wallet is battle tested. I had trouble sending sats to my lightning address today from Phoenix wallet. Hopefully that gets resovled, but I couldn't use it today for whatever reason. I still think it's an awesome idea and will follow this project because I think it has potential.

¹ Stablecoins are shitcoins, but I admit they are not totally useless, but the underlying asset is the epitome of money printer go brrrrrr. ²NVK called cashu an honeset shitcoin on the Bitcoin.review podcast and I've used the term ever sense.

Nos complace presentar a nuestro público lector la obra China y el regreso de Confucio, un compilación de artículos llevada a cabo por prestigioso profesor Carlos X Blanco, autor prolífico y colaborador de Hipérbola Janus, donde nos sentimos honrados y gratificados por sus aportaciones en la difusión de diferentes temas y áreas de conocimiento. En el caso que nos ocupa, el Extremo Oriente sigue siendo un gran desconocido para nosotros, los europeos, especialmente en cuestiones relacionadas con la mentalidad y las ideas que animan la cosmovisión de su nación más representativa, cuya pujanza económica, comercial y geopolítica ha encumbrado a la categoría de superpotencia mundial, hablamos, obviamente, de China. A través de un formato ligero y agradable, como es el diálogo, la obra nos presenta una serie de textos que nos permiten desentrañar las claves del pensamiento confuciano y su desarrollo a lo largo de los siglos XX y XXI. Un breve prólogo a cargo de David Ownby sirve de introducción a la obra. Uno de los ensayos principales es «Un siglo de confucianismo» de Chen Lai (1952), quien estructura el análisis en tres grandes secciones: los desafíos del confucianismo, sus respuestas y las formas en que ha sobrevivido en la era moderna.
En el análisis del Confucianismo, que permanece fuertemente imbricado en la conciencia del pueblo chino, se abordan cuatro grandes desafíos que enumeramos a continuación:
- Reformas políticas y educativas en la era Qing y Republicana (1901-1912): La abolición del sistema de exámenes imperiales debilitó la base institucional del confucianismo, afectando su papel en la sociedad y la educación.
- Movimiento de la Nueva Cultura (1915-1919): Se promovió la modernización basada en la cultura occidental, posicionando al confucianismo como un obstáculo para el progreso.
- Revolución de 1949 y la Revolución Cultural (1966-1976): La colectivización y las comunas populares destruyeron la base social confuciana, mientras que la Revolución Cultural lo atacó ideológicamente.
- Reformas de Deng Xiaoping (1978 en adelante): La modernización y la economía de mercado redujeron la influencia de los valores confucianos frente al pragmatismo y el utilitarismo.
Con anterioridad, el confucianismo siempre ha sido un factor de cohesión nacional, que ha contribuido a preservar la unidad del pueblo chino, especialmente contra las amenazas exteriores, como la que representó el enfrentamiento con Japón desde comienzos de los años 30 del pasado siglo, con la ocupación japonesa de Manchuria, y los sucesivos episodios bélicos vividos contra Japón entre 1937 y 1942.

El texto de Chen Lai toma como punto de partida los últimos años de la Dinastía Qing y los primeros años de la era republicana, entre 1901 y 1912, poniendo especial énfasis en el proceso de modernización emprendido durante esta época, con la introducción de las ciencias y las disciplinas occidentales, hecho que contribuyó a la condena al ostracismo de los clásicos confucianos. Este proceso conoce diversas etapas, a través de las cuales se procede a la abolición del sistema de exámenes imperiales, que durante años se había erigido como el pilar institucional del confucianismo, lo cual trajo como consecuencia inevitable que los eruditos confucianos abandonaran su papel central en la sociedad china. La tendencia a denostar la tradición confuciana se vio incrementada con la transición de la Dinastía de los Qing a los primeros años de la República, como demuestra la eliminación de las ceremonias sacrificiales en honor a Confucio y la prohibición del estudio obligatorio de los clásicos confucianos. De esta manera el confucianismo perdió su papel preponderante en la educación y la administración pública, quedando relegado al ámbito de la ética y la cultura.
Este proceso de rechazo y erosión del confucianismo en su papel de contribución a la identidad nacional china, y a la formación de las nuevas generaciones, se vio acelerado durante las siguientes décadas. Fue un proceso impulsado por intelectuales como Chen Duxiu y Hu Shih, que promovieron activamente la modernización junto con la asunción de valores occidentales como la ciencia o la democracia. Asumiendo posturas análogas a las occidentales en relación a la Tradición, se vio en el confucianismo una forma de pensamiento retrógrado y caduco, frontalmente opuesto al progreso, y por tanto desechable, respecto al cual sus enseñanzas carecían de todo valor operativo en el desarrollo de China. En consecuencia, el confucianismo vivió un ostracismo cultural e intelectual que lo sumió en la más absoluta marginalidad.
Con el advenimiento de la Revolución Cultural China y la conformación del régimen comunista, a partir de 1949 y hasta la muerte de Mao Tse Tung (1893-1976), la situación del confucianismo no mejoró y, muy al contrario, se consideró incompatible con el socialismo marxista. Los ataques se incrementaron y el confucianismo fue objeto de campañas de odio brutales, como aquella desarrollada entre 1973 y 1976, con la «Crítica a Lin Biao y Confucio», en la que se le acusó de «ideología feudal y reaccionaria». La destrucción de templos confucianos y la persecución de sus intelectuales fue un hecho habitual durante este periodo.

En el periodo inmediatamente posterior, a partir de 1978, el factor ideológico se vio atenuado con la llegada de Deng Xiaoping (1904-1997) al poder, y se impuso una época marcada por el pragmatismo y la importancia creciente del desarrollo económico y material. Los ataques al confucianismo cesaron en gran medida, pero se vio sometido a la lógica uniformizadora del utilitarismo y el crecimiento económico.
No obstante, y a pesar de los ataques continuos de los que fue objeto, Chen Lai pone de relieve la resistencia del confucianismo, su voluntad irreductible frente a la amenaza de desaparición, a través de las propuestas de diferentes pensadores confucianos contemporáneos. Es el caso, por ejemplo, de Kang Youwei (1858-1927) con sus propuestas de convertir el confucianismo en religión oficial o integrarlo en el modelo educativo con sus enseñanzas morales sobre el conjunto del pueblo chino. Otros filósofos, como Liang Shuming (1893-1988), trató de superar las antítesis del mundo moderno, y convertir la doctrina de Confucio en parte funcional del socialismo a través de su base moral y social, dado que veía en estas ideas la clave para lograr la armonía y la estabilidad social, tal y como lo había sido en los momentos más delicados de la historia del país asiático.
Paralelamente, intelectuales confucianos como Xiong Shili (1885-1968), Feng Youlan (1895-1990) y He Lin (1902-1992) trataron de aportar nuevos desarrollos a la doctrina confuciana en el terreno de la filosofía y la metafísica. Fruto de estas especulaciones surgieron nuevas escuelas como la «Nueva Filosofía del Principio» de Feng Youlan y la «Nueva Filosofía de la Mente» de He Lin. Tampoco faltaron nuevos intentos de integración entre los valores tradicionales y el socialismo marxista a través de las interpretaciones de Xiong Shili. No será hasta una etapa posterior a la toma del poder de Den Xiaoping que veremos revalorizarse el confucianismo, sometiéndose a un revisionismo que finalmente lo devuelve a las universidades y la sociedad china, momento a partir del cual se recupera su legado como parte de la identidad nacional.
Este proceso de revitalización ha contribuido al estudio del confucianismo y a la aparición de nuevas interpretaciones en las últimas décadas. Las reinterpretaciones del pensamiento confuciano han llevado a la doctrina a un contraste con ideas político-ideológicas del mundo actual, relacionadas con la «democracia», los «derechos humanos» y la «globalización», es decir, con aquellos ítems ideológicos que padecemos en los tiempos postreros, y que están impulsando cambios dramáticos en nuestras sociedades en estos mismos momentos. No obstante, esta recuperación del confucianismo no se ha limitado a las esferas más cultas y académicas, sino que también se ha popularizado, y su presencia en la sociedad china viene siendo cada vez mayor desde la década de los 90, como vemos a través del conocimiento de los clásicos confucianos a través de actividades y cursos dirigidos a la población en general.
De modo que, para Chen Lai, el momento actual, tras la rehabilitación del pensamiento confuciano, es clave para continuar fortaleciendo su doctrina, especialmente por el ascenso de China como potencia mundial, que ha conllevado un creciente interés de China y su cultura más allá de sus fronteras. Pero también, y más allá de aspectos generales y más formales, por el propio contenido ético y moral que le es inherente, y que puede actuar como un freno frente a la corrupción y degradación de los tiempos modernos. De manera que podemos afirmar que es posible una verdadera sinergia entre los valores tradicionales y los nuevos desafíos que la modernidad propone a China, en un frente amplio, en el terreno cultural, político, social etc.
En el segundo capítulo del libro Chen Ming, una de las figuras más importantes del resurgimiento del confucianismo en la China contemporánea aborda la trascendencia de susodicha doctrina en el contexto del Estado y la nación china del siglo XXI. Su enfoque nos proporciona un recorrido a lo largo de aspectos políticos, sociales, educativos, de identidad cultural y la religión, marcando diferencias respecto a otras perspectivas neoconfucianas más orientadas hacia la filosofía o la ética.
Y es que el neoconfucianismo fuera de las fronteras chinas ha diversificado sus corrientes y los temas tratados, y se han centrado en la relación con la democracia, la ciencia y, en definitiva, con su compatibilidad con los valores del liberalismo occidental. Temas que no son nuevos en las derivas interpretativas y especulaciones confucianas del pasado siglo. Un representante destacado de estas últimas posturas es Tu Weiming (1940), filósofo de origen chino nacionalizado estadounidense.
Dentro de la China continental, el discurso confuciano se ha mostrado plenamente funcional a los intereses del Estado chino, contribuyendo a la cimentación de los valores estatales y nacionales, desmarcándose de toda búsqueda de compatibilidad con los valores occidentales, y en su detrimento tratando de fortalecer la identidad cultural china postulándose abiertamente como un pilar fundamental del nacionalismo cultural y político del país asiático. De modo que Chen Ming no ve en la doctrina confuciana un conjunto de ideas abstractas y anacrónicas, sino un potencial en ciernes para seguir pertrechando las bases del Estado y la sociedad china en el mundo actual.
También es importante el análisis que hace del confucianismo frente a la religión, diferenciando sus elementos de toda forma de religión monoteísta, tal y como la concebimos en el «Occidente». No obstante, hay un elemento religioso en su origen, y la idea de un Dios (Shangdi o Tian) como creador y vertebrador de un orden moral. Se puede decir que Confucio transformó este pensamiento en una práctica basada en la ética y la virtud, pero sin eliminar su dimensión espiritual. Algunos intérpretes modernos de la doctrina han tratado de desvirtuar su contenido reduciéndolo a lo que en chino se conoce como «wenjiao» (enseñanza cultural), buscando una fórmula de secularización para despojarla de ese contenido trascendente. Según Chen Ming estos intentos de secularización fueron perpetrados por el Movimiento 4 de mayo a partir de 1919.
No obstante, debemos insistir en que el confucianismo, aún poseyendo una dimensión espiritual, no debe confundirse con nuestro concepto de religión, y hay que poner el énfasis en la idea de estructura moral y social, como una especie de guía moral y espiritual que actúa como antídoto frente a la crisis de los valores tan característica de los tiempos modernos. El texto de Chen Ming también aborda otras problemáticas que no podemos desglosar en la presentación por su amplitud y complejidad, como, por ejemplo, las relaciones del confucianismo con el Estado, el ateísmo del Partido Comunista Chino, la búsqueda de formas de integración y síntesis, cohesión social, el problema de la educación etc. Hay una serie de retos que se presentan a las ideas de Confucio en las que esta búsqueda de encaje en la China contemporánea plantea una serie de desafíos que ponen en riesgo la esencia de su tradición.
El último capítulo del libro está reservado a una entrevista entre Chen Yizhong y Chen Ming en la que se abordan todos los temas que se han tratado en los capítulos anteriores, bajo el formato de un diálogo profundo. Asistimos al contraste de multitud de argumentos sobre el Confucianismo y su relación con la modernidad, con los retos del futuro, con las tensiones y recelos que suscitan los valores liberales y occidentales, totalmente secularizados y, esto lo decimos nosotros, abocados a la destrucción de cualquier fundamento tradicional, étnico o espiritual a todos los niveles.

2025-04-23 12:31:54There’s an annoying trend on Twitter wherein the algorithm feeds you a lot of threads like “five keys to gaining wealth” or “10 mistakes to avoid in relationships” that list a bunch of hacks for some ostensibly desirable state of affairs which for you is presumably lacking. It’s not that the hacks are wrong per se, more that the medium is the message. Reading threads about hacks on social media is almost surely not the path toward whatever is promised by them.
. . .
I’ve tried a lot of health supplements over the years. These days creatine is trendy, and of course Vitamin D (which I still take.) I don’t know if this is helping me, though it surely helps me pass my blood tests with robust levels. The more I learn about health and nutrition, the less I’m sure of anything beyond a few basics. Yes, replacing processed food with real food, moving your body and getting some sun are almost certainly good, but it’s harder to know how particular interventions affect me.
Maybe some of them work in the short term then lose their effect, Maybe some work better for particular phenotypes, but not for mine. Maybe my timing in the day is off, or I’m not combining them correctly for my lifestyle and circumstances. The body is a complex system, and complex systems are characterized by having unpredictable outputs given changes to initial conditions (inputs).
. . .
I started getting into Padel recently — a mini-tennis-like game where you can hit the ball off the back walls. I’d much rather chase a ball around for exercise than run or work out, and there’s a social aspect I enjoy. (By “social aspect”, I don’t really mean getting to know the people with whom I’m playing, but just the incidental interactions you get during the game, joking about it, for example, when you nearly impale someone at the net with a hard forehand.)
A few months ago, I was playing with some friends, and I was a little off. It’s embarrassing to play poorly at a sport, especially when (as is always the case in Padel) you have a doubles partner you’re letting down. Normally I’d be excoriating myself for my poor play, coaching myself to bend my knees more, not go for winners so much. But that day, I was tired — for some reason I hadn’t slept well — and I didn’t have the energy for much internal monologue. I just mishit a few balls, felt stupid about it and kept playing.
After a few games, my fortunes reversed. I was hitting the ball cleanly, smashing winners, rarely making errors. My partner and I started winning games and then sets. I was enjoying myself. In the midst of it I remember hitting an easy ball into the net and reflexively wanting to self-coach again. I wondered, “What tips did I give to right the ship when I had been playing poorly at the outset?” I racked my brain as I waited for the serve and realized, to my surprise, there had been none. The turnaround in my play was not due to self-coaching but its absence. I had started playing better because my mind had finally shut the fuck up for once.
Now when I’m not playing well, I resist, to the extent I’m capable, the urge to meddle. I intend to be more mind-less. Not so much telling the interior coach to shut up but not buying into the premise there is a problem to be solved at all. The coach isn’t just ignored, he’s fired. And he’s not just fired, his role was obsoleted.
You blew the point, you’re embarrassed about it and there’s nothing that needs to be done about it. Or that you started coaching yourself like a fool and made things worse. No matter how much you are doing the wrong thing nothing needs to be done about any of it whatsoever. There is always another ball coming across the net that needs to be struck until the game is over.
. . .
Most of the hacks, habits and heuristics we pick up to manage our lives only serve as yet more inputs in unfathomably complex systems whose outputs rarely track as we’d like. There are some basic ones that are now obvious to everyone like not injecting yourself with heroin (or mRNA boosters), but for the most part we just create more baggage for ourselves which justifies ever more hacks. It’s like taking medication for one problem that causes side effects, and then you need another medicine for that side effect, rinse and repeat, ad infinitum.
But this process can be reverse-engineered too. For every heuristic you drop, the problem it was put into place to solve re-emerges and has a chance to be observed. Observing won’t solve it, it’ll just bring it into the fold, give the complex system of which it is a part a chance to achieve an equilibrium with respect to it on its own.
You might still be embarrassed when you mishit the ball, but embarrassment is not a problem. And if embarrassment is not a problem, then mishitting a ball isn’t that bad. And if mishitting a ball isn’t that bad, then maybe you’re not worrying about what happens if you botch the next shot, instead fixing your attention on the ball. And so you disappear a little bit into the game, and it’s more fun as a result.
I honestly wish there were a hack for this — being more mindless — but I don’t know of any. And in any event, hack Substacks won’t get you any farther than hack Twitter threads.

2025-04-22 18:56:38"It might make sense just to get some in case it catches on. If enough people think the same way, that becomes a self fulfilling prophecy. Once it gets bootstrapped, there are so many applications if you could effortlessly pay a few cents to a website as easily as dropping coins in a vending machine." --Satoshi Nakamoto The Cryptography Mailing List--January 17, 2009
Forgot to add the good part about micropayments. While I don't think Bitcoin is practical for smaller micropayments right now, it will eventually be as storage and bandwidth costs continue to fall. If Bitcoin catches on on a big scale, it may already be the case by that time. Another way they can become more practical is if I implement client-only mode and the number of network nodes consolidates into a smaller number of professional server farms. Whatever size micropayments you need will eventually be practical. I think in 5 or 10 years, the bandwidth and storage will seem trivial. --Satoshi Nakamoto Bitcoin Talk-- August 5, 2010
I very be coded some HTML buttons using Claude and uploaded it to https://github.com/GhostZaps/ It's just a button that links to zapper.fun.
I signed up for Substack to build an email address, but learned adding different payment options to Substack is against their terms and services. Since I write about nostr, these terms seem as silly as someone saying Craig Wright is Satoshi. It's easy to build an audience on Substack however, or so I thought. Why is it easier to build an audience on Subtack though? Because Substack is a platform that markets to writers. Anyone with a ~~pen~~ ~~keyboard~~ smartphone and an email can create an account with Substack. There's just one problem: You are an Internet serf, working the land for your Internet landlord--The Duke of Substack.
Then I saw that Shawn posted about Substack's UX.
I should have grabbed my reading glasses before pushing the post button, but it occurred to me that I could use Ghost to do this and there is probably a way to hack it to accept bitcoin payments over the lightning network and host it yourself. So I spun my noddle, doodled some plans...And then it hit me. Ghost allows for markdown and HTML. I learned HTML and CSS with free-code camp, but ain't nobody got time to type CSS so I vibe-coded a button that ~~baits~~ sends the clicker to my zapper.fun page. This can be used on any blog that allows you to paste html into it so I added it to my Ghost blog self-hosted on a Start 9. The blog is on TOR at http://p66dxywd2xpyyrdfxwilqcxmchmfw2ixmn2vm74q3atf22du7qmkihyd.onion/, but most people around me have been conditioned to fear the dark web so I used the cloudflared to host my newsletter on the clear net at https://marc26z.com/
Integrating Nostr Into My Self-Hosted Ghost Newsletter
I would venture to say I am more technical than the average person and I know HTML, but my CSS is fuzzy. I also know how to print("Hello world!") in python, but I an NPC beyond the basics. Nevertheless, I found that I know enough to make a button. I can't code well enough to create my own nostr long-form client and create plugins for ghost that send lightning payments to lighting channel, but I know enough about nostr to know that I don't need to. That's why nostr is so F@#%-ing cool! It's all connected. ** - One button takes you to zapper.fun where you can zap anywhere between 1 and ,000,000 sats.** - Another button sends you to a zap planner pre-set to send 5,000 sats to the author per month using nostr. - Yet another button sends you to a zap planner preset to send 2,500 sats per month.
The possibilities are endless. I entered a link that takes the clicker to my Shopstr Merch Store. The point is to write as self-sovereign as possible. I might need to change my lightning address when stuff breaks every now and then, but I like the idea of busking for sats by writing on the Internet using the Value 4 Value model. I dislike ads, but I also want people to buy stuff from people I do business with because I want to promote using bitcoin as peer-to-peer electronic cash, not NGU porn. I'm not prude. I enjoy looking at the price displayed on my BlockClock micro every now and then, but I am not an NGU porn addict.
This line made this pattern, that line made this pattern. All that Bolinger Bart Simpson bullshit has nothing to with bitcoin, a peer-to-peer electronic cash system. It is the musings of a population trapped in the fiat mind-set. Bitcoin is permissionless so I realized I was bieng a hipocryte by using a permissioned payment system becaue it was easier than writing a little vibe code. I don't need permission to write for sats. I don't need to give my bank account number to Substack. I don't need to pay a 10$ vig to publish on a a platform which is not designed for stacking sats. I can write on Ghost and integrate clients that already exist in the multi-nostr-verse.
Nostr Payment Buttons
The buttons can be fouund at https://github.com/Marc26z/GhostZapButton
You can use them yourself. Just replace my npub with your npub or add any other link you want. It doesn't technically need to be a nostr link. It can be anything. I have a link to another Ghost article with other buttons that lead down different sat pledging amounts. It's early. Everyone who spends bitcoin is on nostr and nostr is small, but growing community. I want to be part of this community. I want to find other writers on nostr and stay away from Substack.
Here's what it looks like on Ghost: https://marc26z.com/zaps-on-ghost/

@ 0fa80bd3:ea7325de
2025-01-29 05:55:02The land that belongs to the indigenous peoples of Russia has been seized by a gang of killers who have unleashed a war of extermination. They wipe out anyone who refuses to conform to their rules. Those who disagree and stay behind are tortured and killed in prisons and labor camps. Those who flee lose their homeland, dissolve into foreign cultures, and fade away. And those who stand up to protect their people are attacked by the misled and deceived. The deceived die for the unchecked greed of a single dictator—thousands from both sides, people who just wanted to live, raise their kids, and build a future.
Now, they are forced to make an impossible choice: abandon their homeland or die. Some perish on the battlefield, others lose themselves in exile, stripped of their identity, scattered in a world that isn’t theirs.
There’s been endless debate about how to fix this, how to clear the field of the weeds that choke out every new sprout, every attempt at change. But the real problem? We can’t play by their rules. We can’t speak their language or use their weapons. We stand for humanity, and no matter how righteous our cause, we will not multiply suffering. Victory doesn’t come from matching the enemy—it comes from staying ahead, from using tools they haven’t mastered yet. That’s how wars are won.
Our only resource is the will of the people to rewrite the order of things. Historian Timothy Snyder once said that a nation cannot exist without a city. A city is where the most active part of a nation thrives. But the cities are occupied. The streets are watched. Gatherings are impossible. They control the money. They control the mail. They control the media. And any dissent is crushed before it can take root.
So I started asking myself: How do we stop this fragmentation? How do we create a space where people can rebuild their connections when they’re ready? How do we build a self-sustaining network, where everyone contributes and benefits proportionally, while keeping their freedom to leave intact? And more importantly—how do we make it spread, even in occupied territory?
In 2009, something historic happened: the internet got its own money. Thanks to Satoshi Nakamoto, the world took a massive leap forward. Bitcoin and decentralized ledgers shattered the idea that money must be controlled by the state. Now, to move or store value, all you need is an address and a key. A tiny string of text, easy to carry, impossible to seize.
That was the year money broke free. The state lost its grip. Its biggest weapon—physical currency—became irrelevant. Money became purely digital.
The internet was already a sanctuary for information, a place where people could connect and organize. But with Bitcoin, it evolved. Now, value itself could flow freely, beyond the reach of authorities.
Think about it: when seedlings are grown in controlled environments before being planted outside, they get stronger, survive longer, and bear fruit faster. That’s how we handle crops in harsh climates—nurture them until they’re ready for the wild.
Now, picture the internet as that controlled environment for ideas. Bitcoin? It’s the fertile soil that lets them grow. A testing ground for new models of interaction, where concepts can take root before they move into the real world. If nation-states are a battlefield, locked in a brutal war for territory, the internet is boundless. It can absorb any number of ideas, any number of people, and it doesn’t run out of space.
But for this ecosystem to thrive, people need safe ways to communicate, to share ideas, to build something real—without surveillance, without censorship, without the constant fear of being erased.
This is where Nostr comes in.
Nostr—"Notes and Other Stuff Transmitted by Relays"—is more than just a messaging protocol. It’s a new kind of city. One that no dictator can seize, no corporation can own, no government can shut down.
It’s built on decentralization, encryption, and individual control. Messages don’t pass through central servers—they are relayed through independent nodes, and users choose which ones to trust. There’s no master switch to shut it all down. Every person owns their identity, their data, their connections. And no one—no state, no tech giant, no algorithm—can silence them.
In a world where cities fall and governments fail, Nostr is a city that cannot be occupied. A place for ideas, for networks, for freedom. A city that grows stronger the more people build within it.

| |:-:| |LIPOVETSKY, Gilles; La era del vacío; Anagrama, 2006|
El libro que nos disponemos a reseñar hoy es enormemente complejo, y lo es en a medida que cuestiona elementos clave que ayudan a explicar desde el ámbito de la sociología y la filosofía una serie de cambios culturales, sociales y subjetivos en las sociedades occidentales desde mediados del siglo XX en adelante. La era del vacío: Ensayos sobre el individualismo contemporáneo fue publicada originalmente en el año 1983. Con un estilo ensayísticos y profundamente analítico Gilles Lipovetsky nos ofrece un análisis que trasciende los límites de la sociología clásica, al analizar fenómenos tan propios de nuestro tiempo como la subjetividad posmoderna, el hedonismo consumista y el declive de los grandes relatos ideológicos.
Este libro, que fue de una importancia capital en el momento de su publicación y durante la década de los años 80, se puede considerar como el primer intento de sistematizar la posmodernidad más allá de las teorías estéticas, centrándose en aspectos culturales y psicológicos cotidianos. Para Lipovetsky el mundo posmoderno está inmerso en una serie de procesos de mutación que pueden resultar ambiguos, así como tensiones, pero también con nuevas posibilidades.
|
| |:-:| |Gilles Lipovetsky (Millau, Francia, 1944)|
El autor parte de una premisa fundamental: y es que la modernidad ha dado paso a un nuevo estadio de la sociedad, el cual se caracteriza por la disolución de las grandes narrativas colectivas que antes daban sentido de conjunto a las vidas humanas. Frente a la racionalidad industrial, la ética del trabajo y la identidad colectiva que dominaban en los siglos precedentes, el individuo moderno encuentra ahora una posición de autonomía total y radical, pero, como contrapartida, también de vacío existencial. La sociedad de nuestros días, se mueve a un flujo de novedades que tienen un carácter efímero, limitado en el tiempo, consumos inmediatos y obsesión por la apariencia. En este contexto, la promesa de satisfacción inmediata a través del consumo y del individualismo no logra llenar ese vacío interior que se va generando en los individuos.
Lipovetsky describe como, con el advenimiento de la posmodernidad, las promesas de progreso y emancipación se han visto reemplazadas por una búsqueda permanente del placer inmediato, donde lo superficial y lo efímero se convierten en valores predominantes. Es un vacío que va mucho más allá del ámbito social y cultural, y que se extiende también al ámbito de lo subjetivo. El individuo se enfrenta a una sensación de pérdida de sentido que obtiene su mejor reflejo en la percepción de su vida y su relación con los demás. De ahí el título del libro: La era del vacío, que no solamente delata la ausencia de contenido, sino también la falta de profundidad, la superficialidad, que caracteriza a la vida moderna.
Pero el libro no se limita a una mera descripción o diagnóstico de esta situación que acabamos de esbozar, sino que su análisis pretende enfocarse en sus causas. Las transformaciones de la estructura social, la democratización del consumo, el ascenso del neoliberalismo, la tecnificación de las relaciones humanas y, en última instancia, un fenómeno de plena actualidad hoy, en 2025, como es la globalización. Estos son algunos de los factores fundamentales que explican todos estos procesos disolutivos, que Lipovetsky explica desde la perspectiva del sociólogo y el filósofo, manteniendo cierta distancia y ofreciendo respuestas, o soluciones, que huyen de toda simplicidad.
La obra muestra una crítica y escepticismo frente al pensamiento típicamente liberal que nos habla de las ilusiones del progreso y la emancipación total, como parte de las características de la modernidad. Frente a este espejismo, nuestro autor nos invita a reflexionar sobre la necesidad de encontrar nuevos sentidos y valores en un mundo donde éstos parecen desmoronarse por completo. Es una invitación a pensar críticamente sobre nuestra época y reconocer los desafíos que se plantean ante la fragmentación de los grandes relatos de la modernidad y la prevalencia de formas superfluas de existencia.
Uno de los elementos centrales de la obra, como ya hemos señalado al inicio, es la caracterización del hombre contemporáneo como un individuo narcisista, que viene a representar una especie de alternativa frente a la caída de las ideologías, un nuevo tipo humano surgido de la disolución de los grandes relatos colectivos. Y el término no tiene para Lipovetsky ninguna carga peyorativa ni negativa, sino que es un síntoma de esta época, el cual permite comprender cómo ha mutado la subjetividad en el seno de las sociedades del Occidente liberal, en las denominadas «democracias avanzadas».
El narcisista posmoderno no se caracteriza por un ego hipertrofiado en el terreno de lo psicológico, sino por la reorientación de la vida en todos sus aspectos al dominio del yo, que conforma un universo propio, con su bienestar, su apariencia, su desarrollo personal o sus emociones. Es lo que Gilles Lipovetsky concibe como una figura «postheroica», totalmente desvinculada del pathos del sacrificio, del deber, de la militancia política o religiosa. Ha perdido toda conexión con fenómenos de ámbito colectivo, con la lucha de clases propuesta desde filas izquierdistas, por la trascendencia religiosa, ignorando tanto el pasado como el futuro, y radicando su existencia en el presente, en el goce inmediato y la autorrealización subjetiva. Pero conviene insistir en que no se trata de un fenómeno individual o psicológico, sino que obedece a un patrón cultural compartido, moldeado por la lógica del consumo, por la publicidad, por la psicología positiva, por la cultura del entretenimiento y los dispositivos de la autoayuda. Lipovetsky emplea el concepto de «privatización de la existencia» para definir este tipo humano. En el escenario de la vida pública los compromisos ideológicos se diluyen y el ciudadano se transforma en un consumidor, en un mero espectador, en un usuario. La política se reduce a un fenómeno estético, se trivializa y se concibe como un espectáculo, como ese eterno simulacro del que habla Jean Baudrillard o el «postureo» que empleamos desde cierto lenguaje coloquial.
Lejos de advertirse una crítica a este fenómeno, Lipovetsky reconoce en este narcisismo contemporáneo una «forma de emancipación», que a partir de la liberación de los grandes relatos permite formas de vida más «flexibles, más «abiertas» y «tolerantes». Todo ello en un proceso de empobrecimiento del horizonte simbólico, especialmente en lo colectivo, en detrimento del incremento de la autonomía individual. Nosotros añadiríamos, que de una autonomía individual cada vez más atomizada, inorgánica y alienada. De hecho, este individuo hedonista no está dispuesto a sacrificarse por los demás, ni a morir por una causa, y cualquier cosa, por sagrada que sea, es susceptible de ser negociada siempre que revierta en su bienestar.
Las consecuencias derivadas de este proceso, y del nuevo tipo humano posmoderno, son obvias y evidentes, y ahí tenemos la disolución de los lazos sociales fuertes. Vemos cómo las estructuras tradicionales, que han garantizado la cohesión de las comunidades humanas, y que han definido un sentido de pertenencia, un ligamen hacia la Familia, la Religión o la Patria se ven seriamente deteriorados y condenados a desaparecer por completo. Estos elementos han dejado de regular la vida cotidiana, y se imponen vínculos débiles, fluidos y limitados en el tiempo; todo adquiere un sentido limitado en el tiempo, lo efímero domina las relaciones sociales, las afinidades electivas, adquiriendo cierto grado de virtualidad, de ilusorio.
El hombre posmoderno vive rodeado de tecnología, conectado con sus semejantes a través de ordenadores, de las redes sociales, pero solitario, autónomo y desorientado. Con lo cual la «era del vacío» que nos describe Lipovetsky no es realmente un vacío físico o material, sino un vacío simbólico, donde todas las coordenadas que nos conecten a un principio trascendente se encuentran totalmente ausentes. De modo que, el narcisismo clásico de la modernidad más temprana, la que ostentaba el burgués ilustrado, racional y kantiano que creía en la Razón, el Deber o el Progreso, se ha transformado en la posmodernidad, y lo ha hecho a través del narcisista que cree en su «derecho a ser feliz», a «cuidarse» o «experimentar» en una superficialidad que delata la desvinculación de todo centro de gravedad ontológico.
De modo que el hedonismo se nos presenta como el principio rector de la vida social en la era posmoderna, lo cual supone que es una norma compartida, y que conlleva una ética implícita que estructura los comportamientos y aspiraciones, y hasta los valores morales del hombre contemporáneo. Este hecho ha determinado la traslación del «deber» al «placer» en la historia reciente del sujeto occidental, en la que se puede ver cierta idea de «democratización» de esta concepción del narcisismo, de la idea de la «felicidad» y del «culto al yo» en términos puramente materiales, que son transmitidos a través de la publicidad o los manuales de autoayuda.
Este hedonismo está vinculado a una forma particular de existencia, que viene determinada por la lógica del consumo. Y es que para Lipovetsky, como reconoce en otra obra posterior, El imperio de lo efímero, la sociedad ya no se organiza en torno a la producción sino del consumo, entendido éste como el consumo de bienes, experiencias, imágenes, información o sensaciones. De ahí la importancia que poseen para este tipo humano el supermercado, el centro comercial, la pantalla de un ordenador o las redes sociales, que se convierten en el epicentro de la vida posmoderna.

Para Lipovetsky, el acto de consumir no se limita únicamente a las necesidades materiales, sino que se transforma en un «ritual identitario», en una fuente de sentido efímero pero intenso. El hombre posmoderno no compra solo por necesidad, sino para experimentar, como parte de la vida, para definirse. Es un consumo no utilitario, sino expresivo, «para sentirse bien consigo mismo». De modo que este imperativo de bienestar genera una nueva sensibilidad estética: la estética invade la vida cotidiana. La ropa, el diseño interior de una casa, el cuerpo, la alimentación, la música etc, todo se convierte en una cuestión de estilo, en una elección subjetiva. Esto supone que el individuo ya no se define por su pertenencia a un grupo dentro de la jerarquía social ni por su función dentro de la comunidad, sino por su «estética de la existencia». Y es esta estetización de la vida donde, según nuestro autor, reside una forma de construcción de sentido en un mundo desencantado.
No obstante, y siempre según Lipovetsky, este hedonismo posmoderno no se encuentra amparado por el puro libertinaje, sino que el placer también está regulado, normativizado e incluso tecnificado. Lipovetsky insiste en que no se trata de un exceso de placer dionisiaco, sino un placer racionalizado, controlado y saludable. El nuevo hedonista atiende a una responsabilidad, y vemos como hace yoga, se alimenta bien y se cuida en aspectos psicológicos y emocionales. El autor nos habla de un hedonista disciplinado, que gestiona su placer de manera ordenada y eficiente. No obstante, Lipovestsky reconoce que en esta búsqueda del goce y el placer individual, en la búsqueda de una pretendida «libertad» y «autonomía personal», el hedonista posmoderno se somete cada vez más a la tecnología, y es más susceptible de ser controlado por protocolos y normas en nombre de un pretendido bienestar. Todo ello en nombre de lo que en el libro se define como una «reformulación estética y emocional».
Con lo cual, podemos trazar ya en base al libro una cierta definición de la posmodernidad, que más allá de un simple momento histórico, nos ofrece un nuevo marco conceptual, determinado por una transformación profunda a nivel simbólico, ético y estético que han estructurado la cultura llamada occidental desde la Ilustración. Lejos de coincidir con el «fin de la historia» preconizado por Francis Fukuyama, Lipovetsky nos habla de una metamorfosis gradual, caracterizado por la disolución de las grandes narrativas, el debilitamiento del pathos trágico y el auge de la lógica de la inmediatez. Se trata de un enfoque más antropológico y existencial, donde el acento no se pone en una nueva forma de pensar, sino de vivir, de sentir, de relacionarse con el tiempo, con los demás y con uno mismo. Más que una crisis del conocimiento, del saber, se plantea como un reordenamiento del imaginario colectivo, donde el presente hegemoniza todo el interés y se concentra lo trascendente de la escala temporal.
Los grandes ideales desaparecen, aquellos que ofrecían una cierta densidad simbólica y una orientación trascendente. Con la posmodernidad se suprimen las «promesas fuertes» y se promueve una cultura de la «ligereza», de lo provisional, de lo fragmentario. Es un nuevo estilo de vida, menos trágico y combativo, menos solemne, donde lo lúdico y subjetivo acapara amplias cotas de la existencia. Es una mutación cultural donde lo maleable se impone bajo formas de reversibilidad y flexibilidad, todo se hace dúctil, sin compromiso, sin cohesión ni conexión alguna con la trascendencia o sistemas de pensamiento que condicionen la existencia en términos de disciplina y rigidez.
Otro rasgo esencial de la condición del hombre posmoderno es la «evaporación de lo trágico». De algún modo, en la era moderna, el héroe trágico encarnaba la tensión entre el deber y el deseo, entre el orden cósmico y la libertad individual. Sin embargo, en la posmodernidad, esta figura se desvanece, de modo que el sujeto particular ya no se encuentra escindido entre el yo y el deber colectivo, y ahora aparece condicionado por su propio presente, por sus decisiones cotidianas, la gestión de su tiempo, de su cuerpo y cuestiones que se desarrollan en un plano estrictamente personal. La cultura posmoderna evita el conflicto trágico, desplaza la culpa y trivializa el mal. Ya no encontramos el pathos heroico, sino el tono cool, la distancia frente a los hechos y la ironía. Y así tenemos la política convertida en un mero espectáculo, en el arte autorreferencial, en el relativismo moral, y, en definitiva, con un pensamiento débil.
Pero para el sociólogo francés esta ausencia de lo trágico no debe interpretarse como una pérdida, y para él el vacío no es nihilismo, sino una nueva forma de relacionarse con el ser, de manera menos intensa, más liviana, menos sagrada pero más «habitable». El hombre no cae en el desencanto, ni tampoco renuncia a encontrar sentido, pero lo busca de forma dispersa y provisional, sin grandes pretensiones. De este modo la vida se reduce a una relación entre vacío y deseo, entre la autonomía y la saturación de estímulos, que al fin y al cabo supone otro vacío, porque tras la saturación de estímulos solamente hay un sucedáneo de felicidad, dentro de esa tendencia a lo efímero, tras la cual, solo queda el vacío absoluto.
Y es que el diagnóstico que Lipovestsky nos hace de la cultura posmoderna sitúa como elemento central el papel de los medios de comunicación y la cultura del espectáculo. La televisión, el cine y la publicidad, a los que hoy podríamos añadir internet y las redes sociales, no son meros vehículos de información o entretenimiento, sino que son estructuras simbólicas que reconfiguran la sensibilidad, el tiempo y la percepción de la realidad. De hecho son los medios de comunicación de masas los instrumentos y catalizadores en la difusión de la cultura narcisista y el hedonismo personalizado, en la que el principio racional y discursivo cede su lugar a formas más emocionales, fragmentadas y efímeras en la relación con el entorno y el mundo en definitiva. De hecho, el lenguaje de lo visual, totalmente sobredimensionado, ha generado todo un lenguaje que se ha hecho dominante en nuestra época, en el que se privilegia la apariencia y la vivencia subjetiva por encima de toda estructura estable y jerárquica. Y de ahí deriva la espectacularización generalizada a través de la imagen, del impacto que produce, erosionando las fronteras entre lo público y lo privado, entre lo verdadero y simulado, entre el acontecimiento y la escenificación.
En este contexto, el espectador sustituye al ciudadano comprometido, y la política se convierte en un consumo simbólico, en el que el sentido de comunidad es reemplazado por consensos mediáticos efímeros. Para Lipovetsky no es, una vez más, una tragedia, sino que produce un efecto ambivalente: y si bien debilita el compromiso, también produce una sensibilidad más abierta, plural y tolerancia hacia la diferencia. Todo esto, bajo un aparente lenguaje académico y bienpensante, que no hace sino alimentar el pensamiento débil y la destrucción de cualquier idea o principio comunitario sustentado sobre pensamientos fuertes, sobre un principio de jerarquía y cohesión a nivel colectivo.
El hombre posmoderno ignora toda tensión espiritual, y en consecuencia vive la temporalidad de forma acelerada y discontinua, sometido a un flujo incesante de información, de novedades, y concibe su entorno y los estímulos que recibe de éste, desde la perspectiva de la obsolescencia programada. Por eso no se plantea jamás el porvenir e ignora por completo el pasado, para vivir bajo un «presentismo» hedonista, de tal modo que en su percepción del tiempo este no es sino un conjunto de instantes vividos, registrados, compartidos y, en última instancia, olvidados. Así se pierde el sentido de continuidad y duración, impidiendo que tanto a nivel colectivo como individual se pueda construir una identidad coherente o cimentar aquella existente.
Esto lo vemos a través de la cultura digital, aunque en el año que Lipovetsky escribe su libro, en 1983, todavía se encontraba en un estado embrionario o incipiente, pero ya se impone la idea de la hiperconexión, la instantaneidad, la lógica del feed y de la viralidad, que ahondan sobre una experiencia centrífuga del tiempo, donde ya no importa lo que es duradero, sino lo que aparece, lo que afecta y circula en un cambio continuo. De tal modo que el individuo se adapta a la velocidad más que a la profundidad.
Obviamente, la consecuencia es el debilitamiento y la destrucción de todas las formas narrativas tradicionales, tanto a nivel religioso e histórico como ideológico e incluso familiar. Todas estas estructuras, que garantizaron durante generaciones una estabilidad y cohesión en diferentes planos, pierden su poder para dejar su lugar a la cultura de las vivencias dispersas, fragmentadas e inconsistentes. Todo queda reducido al capricho de la experiencia subjetiva del individuo, a sus elecciones de consumo o sus afectos momentáneos. Y tenemos un amplio reflejo de estas ideas en todos los ámbitos, en el arte, en el cine o en la política. La «democratización cultural» y el «pluralismo ético» al que alude el autor, no es sino la destrucción de certezas y principios de carácter vertical, verdades íntegras y sagradas que entran en declive hasta desaparecer.
Ahora bien, una vez destruido el sentido profundo y cohesionador de las grandes instituciones normativas, como la familia, la escuela o el Estado, que sustentaban el cuerpo social mediante su legitimidad simbólica, ¿qué impacto pueden tener sobre los fundamentos éticos y educativos de la sociedad? ¿Qué ocurre con la transmisión de valores, la responsabilidad moral o el pensamiento crítico en una época tan volátil y carente de toda solidez? No existe ningún principio de autoridad en el que cimentar ninguno de estos principios, todo ha sido sacrificado en nombre de la autonomía individual, la horizontalidad y las identidades subjetivas. Es evidente que se ha generado un vacío y la falta de un anclaje o asidero en los procesos educativos. Los profesores ya no encarnan una figura de autoridad, y se encuentran supeditados a las exigencias de los alumnos, a su satisfacción emocional, a su sensibilidad, a garantizar que no se aburran, relegados a una posición de negociación constante. De ahí que la educación y el papel del docente se vea obligado a reformularse y adaptarse a nuevas formas de pedagogía, que en opinión del sociólogo francés, debe adaptarse a la transmisión de conocimientos para «formar subjetividades» dentro de una «pedagogía de la autonomía crítica» que no imponga valores.
En esta era del vacío, caracterizada por el debilitamiento, cuando no aniquilación, de los valores trascendentes, ya no hay una moral universal que pueda orientar las acciones. Lo que prima es una ética débil, individual, basada en la sensibilidad, en la empatía y eso que los progres y globalistas llaman «respeto a la diferencia», que entra en contraste con el desprecio y degradación de lo propio, de lo que le es familiar, de la Tradición en definitiva. Y que lejos de las observaciones de Lipovetsky, sí supone la caída en un relativismo autodestructivo. De hecho, el autor francés ve todas estas transformaciones propiamente posmodernas, de un pensamiento débil, fragmentado, antijerárquico y servil ante cualquier contaminación cultural o asunción de los valores destructivos y globalistas del melting pot como el efecto de una evolución positiva, donde lo emocional y afectivo, lo irracional, invita a la claudicación en nombre de una falsa justicia social, un falso ecologismo o la desfiguración de componentes étnicos, tradicionales e identitarios a nivel colectivo, para defender al modelo multicultural y globalizado, estandarizado y yermo de particularidades. Precisamente lo que hoy tenemos, con países totalmente destruidos en su esencia histórica, étnica y de legados tradicionales en la Europa occidental. Todo en nombre de un pensamiento superficial, fugaz y débil, entregado a los protocolos, normativas e imposiciones de una plutocracia global que somete e impone a una masa idiotizada Agendas en nombre de pretendidos principios de justicia que no son sino la antesala de formas aberrantes y deshumanizadoras de control tecnocrático.
Para terminar, aunque ya hayamos adelantado alguna de nuestras conclusiones respecto al libro, creemos que Gilles Lipovetsky ofrece una visión funcional a la posmodernidad, a la justificación de una serie de transformaciones sociales, culturales, políticas y humanas, que lejos de tener un efecto positivo, de evolución y progreso, envilecen y destruyen a la propia condición humana. La conversión del hombre en un ser infantilizado, egoísta y pusilánime, incapaz de adquirir compromisos colectivos, del sacrificio por grandes ideales que han sustentado modelos de civilización perpetuados en los siglos, no es sino el síntoma de un gran fracaso, de la claudicación del hombre, síntoma de la cultura de la cancelación y la promoción de una antropología negativa y el fomento del nihilismo, por más que se trate de camuflar con eufemismos absurdos y un lenguaje academicista totalmente hueco, retórica vacía, que no deja de ocultar una crítica necesaria frente a cambios estructurales que no son, ni mucho menos, el fruto de una evolución natural, sino totalmente inducidos, y en los que la tecnología sirve de medio de alienación generalizada del sujeto posmoderno. La «era del vacío» de la que nos habla Lipovetsky es una época de decadencia, degeneración, caos y deshumanización, y sin duda alguna es una oportunidad para volver a conectar con el pasado, para religarse con la Tradición e invertir el signo de los tiempos.
Desde un enfoque específicamente tradicionalista, el diagnóstico que Lipovestky nos hace de la sociedad posmoderna, si bien puede ser válido y aceptable desde una perspectiva crítica, resulta insuficiente porque no podemos insertarlo en una cosmovisión propiamente tradicionalista, y suran una sociedad tradicional completamente ajena a los ítems ideológicos que representa esta última. De ahí que la Modernidad, para René Guénon, por ejemplo, represente una desviación extrema de los principios metafísicos y universales que estructuran las civilizaciones tradicionales. Para Lipovetsky esté fenómeno es relativamente reciente, y no el resultado de un proceso histórico amplio y contrastado, que comienza a gestarse en los siglos. Lipovetsky diferencia la modernidad y la posmodernidad, como si fueran dos procesos independientes, en los que solamente nos habla de síntomas sin realizar un análisis de conjunto que llegue a la raíz metafísica del problema. Tanto para René Guénon como para Julius Evola, el individualismo se trata de un proceso de involución espiritual, un descenso hacia lo material y lo informe, algo que no entraña ningún aspecto positivo, y menos en los términos de una «mayor libertad», y donde Lipovetsky ve una posibilidad y una serie de cambios adaptativos, el tradicionalismo ve una forma de claudicación ante lo moderno.
La posición fría, distante y observadora de Lipovetsky difiere radicalmente del tradicionalismo, y no solo por esa ausencia de profundidad en el terreno de lo metafísico, sino porque no ofrece ninguna alternativa al oscurecimiento de lo sagrado, y se limita a una mera descripción de la decadencia, todo desde la perspectiva del científico.
Además, la superficialidad de Lipovetsky se queda únicamente en la catalogación cultural de fenómenos como el hedonismo y el individualismo, sin abordar la radical antítesis que éstos representan frente a lo espiritual. La actitud resignada del sociólogo francés actúa en el marco mental e ideológico de la posmodernidad, frente a la cual no hay que mostrar ningún tipo de alternativa, ni restaurar jerarquías naturales, ni apostar por valores heroicos y aristocráticos, ni mucho menos por la formación de una élite espiritual. Es obvio que el marco conceptual e ideológico en el que actúa este autor es radicalmente ajeno a cualquier concepción morfológica de la historia y concepción tradicional aneja a la misma.
Por otro lado, no se dejan de evidenciar lagunas en su discurso, en la medida que ve en el individualismo el motor de la posmodernidad, y lo asocia a la liberación respecto a las «ataduras» colectivas que representan la Patria, la religión o la comunidad, pero frente a éstas reconoce que solo queda un vacío existencial. Es un individualismo, que nada tiene que ver con aquel individualismo del kshatriya integrado en una jerarquía espiritual, que se erige como guía y estandarte espiritual frente a las naturalezas inferiores. El individualismo posmoderno no tienden a la diferenciación, sino que tiene un efecto de degeneración y envilecimiento a través de la autoexpresión narcisista y el hedonismo, atributos característicos del burgués y de la degenerada antropología liberal.
En definitiva, Lipovetsky es incapaz de proponer una salida positiva al conflicto que plantea la posmodernidad. Para él debe ser aceptado como un estadio inevitable de la historia, mientras que el tradicionalismo exige una ruptura total y absoluta con el mundo moderno, en la que la primacía de los principios metafísicos se convierte en una piedra angular, y son innegociables. El autor francés permanece atrapado en las paradojas y antinomias de un horizonte secular que critica, cayendo en una contradicción insoluble y sin posibilidad de continuidad. La «era del vacío», que abarca un periodo más amplio que el de la propia posmodernidad, representa un punto de ruptura con la Tradición primordial, y plantea una única salida, la cual pasa por la restauración jerárquica y espiritual. No podemos contemplar todos estos procesos disolutivos anejos a nuestro tiempo con la «neutralidad» de Gilles Lipovetsky, sin atender a la existencia de un horizonte metafísico y de Verdades eternas, rescatando el principio de lo Sagrado y la acción heroica en última instancia.

2025-04-28 08:33:05Author: Wanbiao Ye, CKB Core Developer Nervos Network
Secp256k1 and ECDSA aren't just common—they're the backbone of digital signatures in today’s leading blockchains. From Bitcoin (see Bitcoin Wiki) to Ethereum (see Yellow Paper, Appendix E. Precompiled Contract) to CKB (See this RFC), these algorithms are the default choice. They’re what let you prove ownership with your private key — your on-chain assets belong to you, and only you.
Elliptic curves are favored in cryptography because they provide high security with shorter keys. But are they truly secure and perfect? However, the U.S. National Institute of Standards and Technology (NIST) recently indicated concerns about security risks associated with secp256k1 and does not currently endorse its use. Instead, it suggests an alternative curve: secp256r1 (see Recommendations for Discrete Logarithm-based Cryptography, p1). Meanwhile, Bitcoin is evolving—introducing Schnorr signatures in 2021 to replace ECDSA.
The core issue is ECDSA itself—it is highly vulnerable and has caused serious incidents. In this post, we’ll revisit the key attacks, reproduce them, and explain how CKB's segregated witness design and support for upgradable cryptographic algorithms help mitigate these risks. I’ll walk you through a historical overview and attempt to recreate some of the most infamous attacks: nonce reuse attack, invalid curve attack, transaction malleability attacks, and side-channel attacks. Finally, I’ll highlight how CKB addresses these issues through Segregated Witness and support for upgradable cryptographic algorithms—by excluding ECDSA signatures from the transaction hash and enabling algorithm upgrades, so that developers can adopt solutions that best suit their needs without compromising security.
This article uses the following notation:
|
m
| Message | 256-bit integer | | --- | --- | --- | |r
| Part of the signature | 256-bit integer | |s
| Part of the signature | 256-bit integer | |k
| Nonce used during signing | 256-bit integer | |g
| Generator point on the elliptic curve representing (x, y) coordinates | two 256-bit integers |Nonce Reuse Attack
Due to Bitcoin, secp256k1 and ECDSA became widely known. But they weren’t obscure before. For example, Sony used to mark its PlayStation firmware as valid and unmodified using a private key stored at the company's headquarters. PlayStation 3 only requires a public key to verify that the signature is from Sony. But unfortunately, Sony was hacked due to their poor code implementation, meaning that any future system updates they release could be easily decrypted.
At fail0verflow, hackers demonstrated part of Sony’s ECDSA code and discovered that Sony kept the value of the random number always at 4, which caused the random private key
k
in the ECDSA signature process to always have the same value. ECDSA requiresk
to be randomly generated every time. Reusing it leaks the private key.python def get_random_number(): # Chosen by fair dice roll. Guaranteed to be random. return 4
Given:
-
Message
m₁
and signature(r₁, s₁)
-
Message
m₂
and signature(r₂, s₂)
-
Both
m₁
andm₂
are signed with the same unknownk
Then:
```plaintext s₁ = (m₁ + prikey * r₁) / k s₂ = (m₂ + prikey * r₁) / k s₁ / s₂ = (m₁ + prikey * r₁) / (m₂ + prikey * r₁) prikey = (s₁ * m₂ - s₂ * m₁) / (s₂ - s₁) / r₁
```
A real-world example to help you better understand how a private key can be recovered from two signatures that use the same random number
k
:```python import pabtc
m1 = pabtc.secp256k1.Fr(0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e) r1 = pabtc.secp256k1.Fr(0x741a1cc1db8aa02cff2e695905ed866e4e1f1e19b10e2b448bf01d4ef3cbd8ed) s1 = pabtc.secp256k1.Fr(0x2222017d7d4b9886a19fe8da9234032e5e8dc5b5b1f27517b03ac8e1dd573c78)
m2 = pabtc.secp256k1.Fr(0x059aa1e67abe518ea1e09587f828264119e3cdae0b8fcaedb542d8c287c3d420) r2 = pabtc.secp256k1.Fr(0x741a1cc1db8aa02cff2e695905ed866e4e1f1e19b10e2b448bf01d4ef3cbd8ed) s2 = pabtc.secp256k1.Fr(0x5c907cdd9ac36fdaf4af60e2ccfb1469c7281c30eb219eca3eddf1f0ad804655)
prikey = (s1 * m2 - s2 * m1) / (s2 - s1) / r1 assert prikey.x == 0x5f6717883bef25f45a129c11fcac1567d74bda5a9ad4cbffc8203c0da2a1473c ```
Invalid Curve Attack
Invalid Curve Attack involves using points not on the intended curve. Attackers can bypass signature verification or key validation by crafting an invalid public key.
During the signing process, an attacker could somehow construct an invalid public key. This invalid public key has some mathematical relationship with the attacker's private key (for example, the attacker signs by forging an invalid public key), which allows the attacker to generate a seemingly valid signature. Normally, the signature verification algorithm would check whether the public key is within the secp256k1 curve range. If the public key is invalid, the system should reject the signature. However, assuming the system does not perform sufficient curve point validity checks, the attacker could submit a request containing an invalid public key and a forged signature. In some cases, the system might incorrectly accept this invalid signature, considering it as legitimate. The attacker's signature could pass the system's checks, causing malicious transactions or operations to be wrongly considered valid, thus executing certain illegal actions, such as transferring funds or modifying data.
A real-world example is the elliptic curve verification vulnerability in OpenSSL. In 2015, an OpenSSL version prior to v1.0.2 had an elliptic curve verification vulnerability. An attacker could construct an invalid elliptic curve point and use it as a public key, exploiting certain vulnerabilities in OpenSSL to bypass verification, thus attacking systems using the library. This vulnerability, known as CVE-2015-1786, allowed attackers to bypass signature verification by forging an invalid public key. The same issue also occurred in the ECDSA library used by Bitcoin Core, where earlier versions of the library did not perform sufficient checks on elliptic curve points.
Before this vulnerability was fixed, attackers could bypass the system's curve validity checks without proper verification, leading to potential denial of service or other security issues.
Transaction Malleability Attack
In ancient times, if you hammered a gold coin, it changed shape but kept its value. This is called malleability.
Mt. Gox was once the largest Bitcoin exchange in the world. The company, headquartered in Tokyo, is estimated to have accounted for 70% of Bitcoin trading volume in 2013. In 2014, the exchange was hacked, resulting in a loss of approximately 850,000 Bitcoins. The hackers employed a technique known as a transaction malleability attack.
The specific process of the attack is as follows:
-
The attacker initiates a withdrawal Tx A on Mt. Gox
-
Before Tx A is confirmed, it manipulates the transaction's signature, causing the transaction hash, which uniquely identifies the transaction, to change and generating a forged Tx B.
-
Tx B is confirmed on the blockchain, and the exchange receives a failure message for Tx A.
The exchange mistakenly believes that the withdrawal has failed and constructs a new withdrawal transaction for the attacker.
The core of this attack is that the attacker can modify parts of the transaction's signature (such as the input signature) or other non-critical fields, thereby changing the transaction's hash, but without altering the actual content of the transaction.
Coincidentally, secp256k1 + ECDSA indeed provides a very convenient method that allows attackers to modify the signature result while still passing the signature verification. If we analyze the ECDSA signature verification algorithm, we find that the verification result is independent of the sign of the s value in the signature (r, s).
To verify this, we write the following test code:
```python import pabtc
prikey = pabtc.secp256k1.Fr(1) pubkey = pabtc.secp256k1.G * prikey msg = pabtc.secp256k1.Fr(0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e)
r, s, _ = pabtc.ECDSA.sign(prikey, msg) assert pabtc.ECDSA.verify(pubkey, msg, r, +s) assert pabtc.ECDSA.verify(pubkey, msg, r, -s) ```
In the above code, we signed a message with the private key and then took the negative sign of the s value in the signature. We found that the modified signature still passed the ECDSA verification.
Bitcoin had this attack risk in its earlier versions. Attackers used a malleability attack to break the immutability of transactions, leading to severe security issues. To solve this problem, Bitcoin made improvements in the Segregated Witness (SegWit) upgrade. SegWit separated the signature part of the transaction from the other data, so even if the attacker altered the signature part, the transaction hash would no longer be affected, thus solving the transaction malleability issue.
This problem also has similar impacts on other blockchain systems, so many projects have adopted solutions similar to SegWit to ensure the integrity and traceability of transactions. Another solution is the one taken by Ethereum, where additional requirements were imposed on the s value in the signature. Ethereum requires that s must be smaller than
pabtc.secp256k1.N / 2
. You can find Ethereum's detailed solution to the transaction malleability attack in Appendix F. Signing Transactions in its Yellow Paper (p. 26).As a poem goes:
Mt. Gox, the name on the door,
So many users, could there be more?
Bitcoin stolen, hearts hit the floor.
Hashes changed, transactions no more.
Cold wallets emptied, riches out the door,
Gone with the wind, the wealth we adore.Side-Channel Attack
On a flight, I sat next to a man who kept checking stock prices. We chatted briefly, and he mentioned the market was bad this year, then asked me to guess how much he’d lost.
I said, “Probably around a hundred thousand.”
Surprised, he asked how I knew.
I explained: He wore business attire but carried a Swiss Army backpack—clearly not a top exec, more like business development. His Armani watch suggested mid-level income. His shirt was old but well-pressed—his wife likely takes care of him. The Hello Kitty charm on his bag hinted at a young daughter. His stock picks were all tech-related, so he’s probably in the industry. Based on all this, I estimated his disposable capital was around 200–300k, so losing 100k made sense. Dark circles and thinning hair showed stress; his wife likely didn’t know about the losses. I also saw a newly downloaded crypto trading app on his phone—he was probably planning to gamble on crypto next. Then I tapped open his stock app: 280k invested, 102k lost.
He didn’t say another word during the flight. Just sat there, rubbing his eyes. His meal remained untouched.
The story above comes from the Chinese internet, first appearing in 2015. Due to its widespread reposting, the author is unknown. In this story, "I" launched a side-channel attack on the man. Although he didn’t reveal any information about his personal investments, his financial status influences his attire, so we can reverse-engineer his financial situation through his clothing.
In cryptography, a side-channel attack refers to a method of using physical or behavioral information (such as execution time, power consumption, electromagnetic radiation, etc.) generated during a device's operation to break a cryptographic or signature scheme.
For secp256k1 elliptic curve and ECDSA signature schemes, such an attack could infer the private key by analyzing the execution characteristics of crucial operations.
In ECDSA, the signing process involves generating a random number
k
used to calculate part of the signature. The security of this randomk
is crucial; Once leaked, the private key is compromised:Example:
Given the following information, please compute the secp256k1 private key:
plaintext m = 0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e k = 0x1058387903e128125f2715d7de954f53686172b78c3f919521ae4664f30b00ca r = 0x75ee776c554b1dd5e1680a4cc9a3d0e8cb11400742d8af0222ce383e642f98db s = 0x35fd48c9157256558184e20c9392ff3c9517f9753e3745aede06cab285f4bc0d
Answer:
python prikey = (s * k - m) / r assert prikey == 1
The verification code is as follows:
```python import pabtc
m = pabtc.secp256k1.Fr(0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e) k = pabtc.secp256k1.Fr(0x1058387903e128125f2715d7de954f53686172b78c3f919521ae4664f30b00ca) r = pabtc.secp256k1.Fr(0x75ee776c554b1dd5e1680a4cc9a3d0e8cb11400742d8af0222ce383e642f98db) s = pabtc.secp256k1.Fr(0x35fd48c9157256558184e20c9392ff3c9517f9753e3745aede06cab285f4bc0d)
prikey = (s * k - m) / r assert prikey == pabtc.secp256k1.Fr(1) ```
The calculation of the random number
k
involves elliptic curve point multiplication and modular inversion operations (typically implemented using the extended Euclidean algorithm). These operations may have execution times that depend onk
, and side-channel attackers can measure execution time differences to extract information aboutk
. To demonstrate the principle, I will try to simplify the attack process.Example: Suppose there is an unknown random number
k
, and a hacker is somehow able to detect the execution time ofg * k
. Try to see if it's possible to extract some information about the random numberk
.Answer: By examining the point multiplication algorithm on elliptic curves, we find that different operations are executed depending on the bit value of
k
. When a bit is 0, the amount of computation is less than when the bit is 1. We first take two differentk
values—one with most bits being 0, and the other with most bits being 1—and measure the difference in their execution times. Then, when a new unknownk
is used in the computation, we detect its execution time and compare it with the previous two values. This allows us to roughly estimate how many 1 bits are present in the unknownk
.The experimental code is shown below. Note: To simplify the attack steps, in the experimental code we assume that the first bit of all participating
k
values is always 1.```python import pabtc import random import timeit
k_one = pabtc.secp256k1.Fr(0x800000...) k_255 = pabtc.secp256k1.Fr(0x7fffff...) k_unknown = pabtc.secp256k1.Fr(random.randint(0, pabtc.secp256k1.N - 1) | k_one.x)
a = timeit.timeit(lambda: pabtc.secp256k1.G * k_one, number=1024) b = timeit.timeit(lambda: pabtc.secp256k1.G * k_255, number=1024) c = timeit.timeit(lambda: pabtc.secp256k1.G * k_unknown, number=1024)
d = (c - a) / ((b - a) / 254) print(d) ```
The attack process described above is a timing attack, which is a type of side-channel attack. To defend against timing attack, you can introduce constant-time operations in the code to avoid leaking information, such as using fixed-time addition and multiplication operations to prevent timing differences from being exploited.
In real-world applications, preventing side-channel attacks in cryptographic algorithms requires comprehensive security optimizations at the algorithm, hardware, and software levels. However, since the secp256k1 and ECDSA schemes were not designed with such attacks in mind, defending against them is particularly difficult and complex.
CKB's Approach: Segregated Witness + Upgradable Cryptographic Algorithms
In terms of transaction structure, CKB adopts Bitcoin’s Segregated Witness scheme, meaning that the transaction hash does not include the ECDSA signature. This design helps prevent transaction malleability attacks. See the Transaction Hash section of the RFC for details.
The Secp256k1 + ECDSA scheme is CKB’s default signature scheme, but thanks to CKB’s custom cryptographic primitives and native account abstraction capabilities, we can easily implement many other cryptographic algorithms in CKB, as well as upgrade existing ones. Developers on CKB are free to choose any algorithm they trust to protect the assets, including but not limited to:
Final Remarks
In short, although secp256k1 and ECDSA are widely used and quite secure when implemented properly and used correctly, we still must not overlook some of their potential vulnerabilities. Thanks to Bitcoin’s development, secp256k1 and ECDSA have gained great fame, but they have also attracted more attention from cryptographers and malicious hackers. In the future, more types of attacks on secp256k1 may be gradually discovered and exploited. Therefore, staying vigilant, updating in time, and following the latest security best practices is critical for maintaining system security. As the field of cryptography continues to advance, there are already some more secure and efficient alternatives available. But regardless of this, understanding and addressing current risks remains the responsibility and challenge of every developer.

Secp256k1 与 ECDSA 椭圆曲线不仅常见,更是当今区块链数字签名的基础。从比特币(见 Bitcoin Wiki)到以太坊(见 Yellow Paper, Appendix E. Precompiled Contract)再到 CKB (见 RFC 24 相关部分) ,secp256k1 + ECDSA 都是它们的默认选择。它们让你通过私钥证明所有权——你的链上资产属于你,且仅属于你。
椭圆曲线之所以在密码学中有优势,因为它们可以在较小的密钥长度下提供更高的安全性。 但是, 它们真的是安全且完美的算法吗?美国国家标准与技术研究院(NIST)最近认为 secp256k1 存在一些安全风险,已经不建议使用。作为替代,它们建议使用另一条名为 secp256r1 的椭圆曲线(见 Recommendations for Discrete Logarithm-based Cryptography, p1)。另一方面,比特币自身也在改变——在 2021 年引入了一种叫做 Schnorr 的签名算法来尝试替代 ECDSA。
促成这些改变的本质原因是因为 ECDSA 签名算法自身的问题——极其容易受到攻击,并造成过许多灾难性的后果。在本次分享中,我将带领大家回顾历史,并尝试重现这些历史上的著名攻击:随机数重用攻击、心脏点攻击、交易延展攻击、旁路攻击。最后我将指出 CKB 所采用的隔离见证,配合支持加密算法升级的方式——交易哈希不包含 ECDSA 签名,并允许算法升级,在确保安全的同时让用户可以采用更适合自己需求的方案。

因为比特币的原因,secp256k1 椭圆曲线以及 ECDSA 签名算法变得无人不知、无人不晓。但其实在比特币之前,它们也并非无人问津。例如在 Playstation 3 时代,索尼就使用存储在公司总部的私钥将其 Playstation 固件标记为有效且未经修改。Playstation 3 只需要一个公钥来验证签名是否来自索尼。 但不幸的是,索尼因为他们糟糕的代码实现而遭到了黑客的破解,这意味着他们今后发布的任何系统更新都可以毫不费力地解密。
在 fail0overflow 大会上, 黑客展示了索尼 ECDSA 的部分代码, 发现索尼让随机数的值始终保持 4, 这导致了 ECDSA 签名步骤中的随机私钥 k 始终会得到相同的值。ECDSA 签名要求随机数 k 是严格随机的, 如果重复使用 k, 将直接导致私钥泄露.
python get_random_number(): # Chosen by fair dice roll. Guaranteed to be random. return 4
例:有以下信息,求私钥 prikey
-
信息 m₁ 及其签名 (r₁, s₁);
-
信息 m₂ 及其签名 (r₂, s₂);
-
信息 m₁ 和 m₂ 使用相同的随机数 k 进行签名, k 的具体数据则未知。
答:
plaintext s₁ = (m₁ + prikey * r₁) / k s₂ = (m₂ + prikey * r₂) / k = (m₂ + prikey * r₁) / k s₁ / s₂ = (m₁ + prikey * r₁) / (m₂ + prikey * r₁) prikey = (s₁ * m₂ - s₂ * m₁) / (s₂ - s₁) / r₁
这里有一个实际的例子可以帮助大家更直观的理解,如何通过两个使用相同随机数 k 的签名来还原私钥:
```python import pabtc
m1 = pabtc.secp256k1.Fr(0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e) r1 = pabtc.secp256k1.Fr(0x741a1cc1db8aa02cff2e695905ed866e4e1f1e19b10e2b448bf01d4ef3cbd8ed) s1 = pabtc.secp256k1.Fr(0x2222017d7d4b9886a19fe8da9234032e5e8dc5b5b1f27517b03ac8e1dd573c78)
m2 = pabtc.secp256k1.Fr(0x059aa1e67abe518ea1e09587f828264119e3cdae0b8fcaedb542d8c287c3d420) r2 = pabtc.secp256k1.Fr(0x741a1cc1db8aa02cff2e695905ed866e4e1f1e19b10e2b448bf01d4ef3cbd8ed) s2 = pabtc.secp256k1.Fr(0x5c907cdd9ac36fdaf4af60e2ccfb1469c7281c30eb219eca3eddf1f0ad804655)
prikey = (s1 * m2 - s2 * m1) / (s2 - s1) / r1 assert prikey.x == 0x5f6717883bef25f45a129c11fcac1567d74bda5a9ad4cbffc8203c0da2a1473c ```
心脏点攻击
心脏点攻击(invalid curve attacks)指攻击者通过生成不在标准曲线上的点,通过这种方式绕过签名验证、密钥生成或者其他基于曲线的操作。
在签名过程中,攻击者可以通过某种方式构造一个无效的公钥。该无效公钥与攻击者的私钥之间存在某种数学关系(例如,攻击者通过伪造一个无效的公钥进行签名),这使得攻击者能够生成一个看似有效的签名。正常情况下,签名验证算法会检查公钥是否在 secp256k1 曲线范围内。如果公钥无效,系统应该拒绝该签名。但是,假设系统没有进行充分的曲线点有效性检查,攻者可能会提交一个包含无效公钥和伪造签名的请求。在某些情况下,系统可能会错误地接受这个无效签名,认为它是合法的。攻击者的签名可能会通过系统的检查,导致恶意的交易或操作被错误地认为是有效的,从而执行某些非法操作,比如转移资金或修改数据。
一个现实中的例子是 OpenSSL 中的椭圆曲线验证漏洞。2015 年,OpenSSL v1.0.2 之前的一个版本存在一个椭圆曲线验证漏洞。攻击者可以通过构造一个无效的椭圆曲线点并将其用作公钥, 利用 OpenSSL 的某些漏洞绕过验证,进而攻击使用该库的系统。这个漏洞被称为 CVE-2015-1786, 它允许攻击者通过伪造无效的公钥来绕过签名验证。同样的问题也曾发生在 Bitocin Core 使用的 ECDSA 库中,早期版本的库没有对椭圆曲线点进行足够的检查。
在这个漏洞被修复之前,攻击者可以在不进行正确验证的情况下,绕过系统对曲线有效性的检查, 从而导致可能的拒绝服务或其他安全问题。
交易延展性攻击
在古代,如果我们把一枚金币敲变形之后,虽然形状有所改变,但质量却没有发生变化,在市场交易中它仍然会被认可为一枚金币,甚至您将金币敲成金块,它依然会被认可,这种特性呢被称为“延展性”或“可锻性”。
Mt. Gox(门头沟)一度是世界上最大的比特币交易所。该公司总部位于东京,估计 2013 年占比特币交易量的 70%。2014 年,门头沟交易所被黑客攻击,造成了约 85 万枚比特币的损失。在门头沟事件中,黑客所采用的是一种名为交易延展性攻击(transaction malleability attack)的手法。
此次攻击的具体过程如下:攻击者首先在门头沟发起一笔提现交易 a, 接着在交易 a 被确认之前通过篡改交易签名,使得标识一笔交易唯一性的交易哈希发生改变,生成伪造的交易 b。之后,交易 b 被区块链确认,而交易所则收到了交易 a 失败的信息。交易所误认为提现失败从而重新为攻击者构造一笔新的提现交易。
要使得攻击成立,其核心是攻击者能够修改交易的签名部分(如输入的签名)或者其他非关键的字段, 从而改变交易的哈希值,但不会改变交易的实际内容.
巧合的是,secp256k1 + ECDSA 确实存在一种十分便捷的方式,使得攻击者可以修改签名结果的同时仍然能通过签名验证。如果我们分析 ECDSA 验签算法,会发现验签结果和签名(r, s)中的 s 值的符号是无关的。
为了验证这一点,我们编写如下测试代码:
```python import pabtc prikey = pabtc.secp256k1.Fr(1) pubkey = pabtc.secp256k1.G * prikey msg = pabtc.secp256k1.Fr(0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e)
r, s, _ = pabtc.ECDSA.sign(prikey, msg) assert pabtc.ECDSA.verify(pubkey, msg, r, +s) assert pabtc.ECDSA.verify(pubkey, msg, r, -s) ``` 在上述代码中,我们使用私钥对一条消息进行了签名,然后对签名中的 s 值取负号,发现修改后的签名依然能通过 ECDSA 验证。
比特币在早期版本中存在这种攻击的风险,攻击者通过延展性攻击破坏了交易的不可篡改性,导致了严重的安全问题。为了解决这一问题,比特币在 Segregated Witness (SegWit) 升级中做了改进,SegWit 将交易的签名部分与其他数据分开存储,使得即使攻击者篡改签名部分,交易哈希也不再受影响,从而解决了交易延展性问题。
这个问题在其他区块链系统中也有类似的影响,因此许多项目都采取了类似 SegWit 的解决方案,来确保交易的完整性和可追溯性。另一种解决方案是以太坊所采取的,以太坊对签名中的 s 做了额外的要求,要求 s 必须小于
pabtc.secp256k1.N / 2
。您可以在 Ethereum Yellow paper 的 Appendix F. Signing Transactions (p. 26) 部分找到以太坊针对交易延展性攻击的详细解决方式。有诗云:
门头交易所,用户真是多,
比特币被盗,大伙冷汗冒,
黑客改哈希,交易无踪兆,
冷钱包空空,财富随风飘。旁路攻击
我坐飞机旁边有个大哥一直在看股票,我俩聊了几句股票。他说今年行情不好,让我猜他亏了多少钱。
我说:“也就十来万吧。”
大哥一愣,问我:“你咋猜的呢?”
我说:“虽然你穿着衬衫西裤,看着很商务,但是却背了个瑞士军刀牌双肩包,大老板有背这个的么?一看你就是个跑业务的。再看你戴了块阿玛尼这种杂牌子手表,三十多岁的人了,连个劳力士都没混上,说明收入很一般。你的衬衣是旧的,但是熨得很板正,领子也干净,这都是你老婆给你收拾的。你包上有个 HelloKitty 小挂件,这应该是你女儿给你挂的。你自选股里都是一些 5G 移动芯片之类的股票,你觉得自己很懂,你应该是互联网企业上班的。方方面面综合下来,你的可支配资金也就 20-30 万,结合今年的行情,亏损 10 万左右。再看看你这个黑眼圈和与年龄不成比例的稀疏发型,压力不小。你老婆应该还不知道你股票亏了这么多钱。刚才看到你手机界面上还有炒虚拟币的软件,在最后一位,说明是最近刚刚下载的。如果你股票再亏,你就打算去炒虚拟币放手一搏,但是你只会亏得更惨。说完我点了下他手机炒股软件界面,上面显示总投入 28 万,当前亏损 10.2 万。”
大哥沉默了,一路上再也没跟我说一句话,只是偶尔低头用食指关节揉一揉微微发红的的眼眶,飞机餐的盒饭打开了,但是没吃。
上述故事来自中国互联网, 最早出现在 2015 年,由于被转载太多次,因此作者实在不明。在这个故事里,“我”就对大哥发动了一次旁路攻击。大哥虽然没有向我透露任何关于自身的投资信息,但是由于大哥的资产收益会影响大哥的穿着,因此我们可以通过大哥的穿着来反向推断大哥的资产收益。
在密码学中,所谓的旁路攻击(side-channel attacks),就是一种利用设备执行任务时产生的物理或行为信息(如执行时间、用电模式、电磁辐射等)来破解密码或签名方案的方法。对于 secp256k1 椭圆曲线和 ECDSA 签名方案,这种攻击可能通过分析关键运算的执行特性来推断私钥。
在 ECDSA 中,签名过程涉及生成一个随机数 k,然后用它来计算签名的一部分。这个随机数的安全性至关重要,如果 k 被泄漏,攻击者就能通过它恢复私钥.
例:有以下信息,请计算 secp256k1 的私钥:
-
消息
m = 0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e
-
随机数字
k = 0x1058387903e128125f2715d7de954f53686172b78c3f919521ae4664f30b00ca

s = 0x35fd48c9157256558184e20c9392ff3c9517f9753e3745aede06cab285f4bc0d
答:根据 ECDSA 签名算法,容易得到私钥计算公式为
prikey = (s * k - m) / r
, 代入数字计算,得到私钥为 1。验证代码如下:
```python import pabtc
m = pabtc.secp256k1.Fr(0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e) k = pabtc.secp256k1.Fr(0x1058387903e128125f2715d7de954f53686172b78c3f919521ae4664f30b00ca) r = pabtc.secp256k1.Fr(0x75ee776c554b1dd5e1680a4cc9a3d0e8cb11400742d8af0222ce383e642f98db) s = pabtc.secp256k1.Fr(0x35fd48c9157256558184e20c9392ff3c9517f9753e3745aede06cab285f4bc0d)
prikey = (s * k - m) / r assert prikey == pabtc.secp256k1.Fr(1) ```
随机数字 k 的计算涉及到椭圆曲线点乘和逆元操作(通常通过扩展欧几里得算法实现)。这些操作的时间可能会与 k 相关,旁路攻击者可以测量执行时间差异来提取 k。为了揭示原理,我将尝试把攻击过程简化。
例:有未知随机数字 k,现在黑客通过某种手段可探测出
g * k
的执行时间,请尝试是否可以得到随机数字 k 的一些信息。答:观察椭圆曲线上的点的乘法算法,得出当 k 的比特位不同时,会执行不同的操作。当比特位为 0 时,其计算量小于比特位为 1 时。我们事先取两个不同的 k 值,一个大多数位为 0,另一个大多数位位 1,计算它们的执行时间之差。当有新的未知 k 进行计算时,探测得到它的执行时间,与前两个值进行比对,可大致得到未知 k 其比特位为 1 的数量。实验代码如下。注意,为了简化攻击步骤,在实验代码中我们假设所有参与计算的 k 的第一个比特位始终为 1。
```python import pabtc import random import timeit
k_one = pabtc.secp256k1.Fr(0x8000000000000000000000000000000000000000000000000000000000000000) # Has one '1' bits k_255 = pabtc.secp256k1.Fr(0x7fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff) # Has 255 '1' bits k_unknown = pabtc.secp256k1.Fr(random.randint(0, pabtc.secp256k1.N - 1) | k_one.x) # The unknown k
a = timeit.timeit(lambda: pabtc.secp256k1.G * k_one, number=1024) b = timeit.timeit(lambda: pabtc.secp256k1.G * k_255, number=1024) c = timeit.timeit(lambda: pabtc.secp256k1.G * k_unknown, number=1024)
d = (c - a) / ((b - a) / 254) print(d) ```
上述攻击过程是旁路攻击中的时间攻击(timing attacks),如果要对该攻击做防护,可以通过在代码中引入常量时间操作(constant-time operations)来避免泄露信息。例如,使用固定时间的加法和乘法,防止时间差异被利用。
在实际应用中,为了避免密码学算法中的旁路攻击,需要在算法、硬件和软件层面做出多方面的安全优化。不过由于 secp256k1 与 ECDSA 方案在设计时未充分考虑该攻击方式,因此防护此类攻击非常困难且复杂。
CKB 的方式:隔离见证 + 加密算法可升级
在交易结构上,CKB 采用了比特币的隔离见证方案,也就是交易哈希不会包含 ECDSA 签名。这种设计可以防止交易延展性攻击。详情见 RFC 的 Transaction Hash 部分。
Secp256k1 + ECDSA 方案是 CKB 的默认签名方案,但得益于 CKB 的自定义密码学原语和原生账户抽象能力,在 CKB 上可以非常容易地实现更多其它加密算法和升级现有算法。CKB 上的开发者可以选择任意信任算法来保护资产,包括但不限于:
-
RSA, Ed25519 and more
结语
总之,虽然 secp256k1 和 ECDSA 在许多应用中广泛使用,并且它们在合理的实现和正确的使用下是相当安全的,但也不能忽视它们存在的一些潜在漏洞。得益于比特币的发展,secp256k1 和 ECDSA 名声大噪的同时也吸引了更多的密码学家和不怀好意的黑客们。未来,更多关于 sepc256k1 的一些攻击方式可能会逐步被发现并利用。因此,保持警惕,及时更新以及遵循最新的安全最佳实践对于确保系统安全至关重要。随着加密领域的不断进步,目前已经有一些更加安全且高效的替代方案出现。但无论如何,理解并应对当前的风险,仍然是我们每一个开发者的责任和挑战。

@ 1c19eb1a:e22fb0bc
2025-04-22 01:36:33After my first major review of Primal on Android, we're going to go a very different direction for this next review. Primal is your standard "Twitter clone" type of kind 1 note client, now branching into long-form. They also have a team of developers working on making it one of the best clients to fill that use-case. By contrast, this review will not be focusing on any client at all. Not even an "other stuff" client.
Instead, we will be reviewing a very useful tool created and maintained by nostr:npub1w4uswmv6lu9yel005l3qgheysmr7tk9uvwluddznju3nuxalevvs2d0jr5 called #Amber. For those unfamiliar with Amber, it is an #Android application dedicated to managing your signing keys, and allowing you to log into various #Nostr applications without having to paste in your private key, better known as your #nsec. It is not recommended to paste your nsec into various applications because they each represent another means by which it could be compromised, and anyone who has your nsec can post as you. On Nostr, your #npub is your identity, and your signature using your private key is considered absolute proof that any given note, reaction, follow update, or profile change was authorized by the rightful owner of that identity.
It happens less often these days, but early on, when the only way to try out a new client was by inputting your nsec, users had their nsec compromised from time to time, or they would suspect that their key may have been compromised. When this occurs, there is no way to recover your account, or set a new private key, deprecating the previous one. The only thing you can do is start over from scratch, letting everyone know that your key has been compromised and to follow you on your new npub.
If you use Amber to log into other Nostr apps, you significantly reduce the likelihood that your private key will be compromised, because only one application has access to it, and all other applications reach out to Amber to sign any events. This isn't quite as secure as storing your private key on a separate device that isn't connected to the internet whatsoever, like many of us have grown accustomed to with securing our #Bitcoin, but then again, an online persona isn't nearly as important to secure for most of us as our entire life savings.
Amber is the first application of its kind for managing your Nostr keys on a mobile device. nostr:npub1w4uswmv6lu9yel005l3qgheysmr7tk9uvwluddznju3nuxalevvs2d0jr5 didn't merely develop the application, but literally created the specification for accomplishing external signing on Android which can be found in NIP-55. Unfortunately, Amber is only available for Android. A signer application for iOS is in the works from nostr:npub1yaul8k059377u9lsu67de7y637w4jtgeuwcmh5n7788l6xnlnrgs3tvjmf, but is not ready for use at this time. There is also a new mobile signer app for Android and iOS called Nowser, but I have not yet had a chance to try this app out. From a cursory look at the Android version, it is indeed in the very early stages of development and cannot be compared with Amber.
This review of Amber is current as of version 3.2.5.
Overall Impression
Score: 4.7 / 5 (Updated 4/21/2025)
I cannot speak highly enough about Amber as a tool that every Nostr user on Android should start using if they are not already. When the day comes that we have more options for well-developed signer apps on mobile, my opinion may very well change, but until then Amber is what we have available to us. Even so, it is an incredibly well thought-out and reliable tool for securing your nsec.
Despite being the only well-established Android signer available for Android, Amber can be compared with other external signing methods available on other platforms. Even with more competition in this arena, though, Amber still holds up incredibly well. If you are signing into web applications on a desktop, I still would recommend using a browser extension like #Alby or #Nos2x, as the experience is usually faster, more seamless, and far more web apps support this signing method (NIP-07) than currently support the two methods employed by Amber. Nevertheless that gap is definitely narrowing.
A running list I created of applications that support login and signing with Amber can be found here: Nostr Clients with External Signer Support
I have run into relatively few bugs in my extensive use of Amber for all of my mobile signing needs. Occasionally the application crashes when trying to send it a signing request from a couple of applications, but I would not be surprised if this is no fault of Amber at all, and rather the fault of those specific apps, since it works flawlessly with the vast majority of apps that support either NIP-55 or NIP-46 login.
I also believe that mobile is the ideal platform to use for this type of application. First, because most people use Nostr clients on their phone more than on a desktop. There are, of course, exceptions to that, but in general we spend more time on our phones when interacting online. New users are also more likely to be introduced to Nostr by a friend having them download a Nostr client on their phone than on a PC, and that can be a prime opportunity to introduce the new user to protecting their private key. Finally, I agree with the following assessment from nostr:npub1jlrs53pkdfjnts29kveljul2sm0actt6n8dxrrzqcersttvcuv3qdjynqn.
nostr:nevent1qqsw0r6gzn05xg67h5q2xkplwsuzedjxw9lf7ntrxjl8ajm350fcyugprfmhxue69uhhyetvv9ujumn0wd68yurvv438xtnrdaksyg9hyaxj3clfswlhyrd5kjsj5v04clhjvgeq6pwztmysfzdvn93gev7awu9v
The one downside to Amber is that it will be quite foreign for new users. That is partially unavoidable with Nostr, since folks are not accustomed to public/private key cryptography in general, let alone using a private key to log into websites or social media apps. However, the initial signup process is a bit cumbersome if Amber is being used as the means of initially generating a key pair. I think some of this could be foregone at start-up in favor of streamlining onboarding, and then encourage the user to back-up their private key at a later time.
Features
Amber has some features that may surprise you, outside of just storing your private key and signing requests from your favorite Nostr clients. It is a full key management application, supporting multiple accounts, various backup methods, and even the ability to authorize other users to access a Nostr profile you control.
Android Signing
This is the signing method where Amber really shines in both speed and ease of use. Any Android application that supports this standard, and even some progressive web-apps that can be installed to your Android's home-screen, can very quickly and seamlessly connect with Amber to authorize anything that you need signed with your nsec. All you have to do is select "Login with Amber" in clients like #Amethyst or #0xChat and the app will reach out to Amber for all signing requests from there on out. If you had previously signed into the app with your nsec, you will first need to log out, then choose the option to use Amber when you log back in.
This is a massive deal, because everything you do on Nostr requires a signature from your private key. Log in? Needs a signature. Post a "GM" note? Needs a signature. Follow someone who zapped your note? Needs a signature. Zap them back? You guessed it; needs a signature. When you paste your private key into an application, it will automatically sign a lot of these actions without you ever being asked for approval, but you will quickly realize just how many things the client is doing on your behalf when Amber is asking you to approve them each time.
Now, this can also get quite annoying after a while. I recommend using the setting that allows Amber to automatically sign for basic functions, which will cut down on some of the authorization spam. Once you have been asked to authorize the same type of action a few times, you can also toggle the option to automatically authorize that action in the future. Don't worry, though, you have full control to require Amber to ask you for permission again if you want to be alerted each time, and this toggle is specific to each application, so it's not a blanket approval for all Nostr clients you connect with.
This method of signing is just as fast as signing via browser extension on web clients, which users may be more accustomed to. Everything is happening locally on the device, so it can be very snappy and secure.
Nostr Connect/Bunker Signing
This next method of signing has a bit of a delay, because it is using a Nostr relay to send encrypted information back and forth between the app the user is interacting with and Amber to obtain signatures remotely. It isn't a significant delay most of the time, but it is just enough to be noticeable.
Also, unlike the previous signing method that would automatically switch to Amber as the active application when a signing request is sent, this method only sends you a notification that you must be watching for. This can lead to situations where you are wondering why something isn't working in a client you signed into remotely, because it is waiting on you to authorize the action and you didn't notice the notification from Amber. As you use the application, you get used to the need to check for such authorization requests from time to time, or when something isn't working as expected.
By default, Amber will use relay.nsec.app to communicate with whichever Nostr app you are connecting to. You can set a different relay for this purpose, if you like, though not just any relay will support the event kinds that Amber uses for remote signing. You can even run your own relay just for your own signing purposes. In fact, the creator of Amber has a relay application you can run on your phone, called Citrine, that can be used for signing with any web app you are using locally on your phone. This is definitely more of an advanced option, but it is there for you if you want it. For most users, sticking with relay.nsec.app will be just fine, especially since the contents of the events sent back and forth for signing are all encrypted.
Something many users may not realize is that this remote signing feature allows for issuing signing permissions to team members. For instance, if anyone ever joined me in writing reviews, I could issue them a connection string from Amber, and limit their permissions to just posting long-form draft events. Anything else they tried to do would require my explicit approval each time. Moreover, I could revoke those permissions if I ever felt they were being abused, without the need to start over with a whole new npub. Of course, this requires that your phone is online whenever a team member is trying to sign using the connection string you issued, and it requires you pay attention to your notifications so you can approve or reject requests you have not set to auto-approve. However, this is probably only useful for small teams, and larger businesses will want to find a more robust solution for managing access to their npub, such as Keycast from nostr:npub1zuuajd7u3sx8xu92yav9jwxpr839cs0kc3q6t56vd5u9q033xmhsk6c2uc.
The method for establishing a connection between Amber and a Nostr app for remote signing can vary for each app. Most, at minimum, will support obtaining a connection string from Amber that starts with "bunker://" and pasting it in at the time of login. Then you just need to approve the connection request from Amber and the client will log you in and send any subsequent signing requests to Amber using the same connection string.
Some clients will also offer the option to scan a QR code to connect the client to Amber. This is quite convenient, but just remember that this also means the client is setting which relay will be used for communication between the two. Clients with this option will also have a connection string you can copy and paste into Amber to achieve the same purpose. For instance, you may need this option if you are trying to connect to an app on your phone and therefore can't scan the QR code using Amber on the same phone.
Multiple Accounts
Amber does not lock you into using it with only a single set of keys. You can add all of your Nostr "accounts" to Amber and use it for signing events for each independently. Of course, Nostr doesn't actually have "accounts" in the traditional sense. Your identity is simply your key-pair, and Amber stores and accesses each private key as needed.
When first signing in using native Android signing as described above, Amber will default to whichever account was most recently selected, but you can switch to the account that is needed before approving the request. After initial login, Amber will automatically detect the account that the signing request is for.
Key Backup & Restore
Amber allows multiple ways to back up your private key. As most users would expect, you can get your standard nsec and copy/paste it to a password manager, but you can also obtain your private key as a list of mnemonic seed words, an encrypted version of your key called an ncryptsec, or even a QR code of your nsec or ncryptsec.
Additionally, in order to gain access to this information, Amber requires you to enter your device's PIN or use biometric authentication. This isn't cold-storage level protection for your private key by any means, especially since your phone is an internet connected device and does not store your key within a secure element, but it is about as secure as you can ask for while having your key accessible for signing Nostr events.
Tor Support
While Amber does not have Tor support within the app itself, it does support connecting to Tor through Orbot. This would be used with remote signing so that Amber would not connect directly over clearnet to the relay used for communication with the Nostr app requesting the signature. Instead, Amber would connect through Tor, so the relay would not see your IP address. This means you can utilize the remote signing option without compromising your anonymity.
Additional Security
Amber allows the user the option to require either biometric or PIN authentication before approving signing requests. This can provide that extra bit of assurance that no one will be able to sign events using your private key if they happen to gain access to your phone. The PIN you set in Amber is also independent from the PIN to unlock your device, allowing for separation of access.

At the end of the day, Amber is a tool for those who have some concept of the importance of protecting their private key by not pasting it into every Nostr client that comes along. This concept in itself is not terribly approachable to an average person. They are used to just plugging their password into every service they use, and even worse, they usually have the same password for everything so they can more readily remember it. The idea that they should never enter their "Nostr password" into any Nostr application would never occur to them unless someone first explained how cryptography works related to public/private key pairs.
That said, I think there can be some improvements made to how users are introduced to these concepts, and that a signer application like Amber might be ideal for the job. Considering Amber as a new user's first touch-point with Nostr, I think it holds up well, but could be somewhat streamlined.
Upon opening the app, the user is prompted to either use their existing private key or "Create a new Nostr account." This is straightforward enough. "Account" is not a technically correct term with Nostr, but it is a term that new users would be familiar with and understand the basic concept.
The next screen announces that the account is ready, and presents the user with their public key, explaining that it is "a sort of username" that will allow others to find them on Nostr. While it is good to explain this to the user, it is unnecessary information at this point. This screen also prompts the user to set a nickname and set a password to encrypt their private key. Since the backup options also allow the user to set this password, I think this step could be pushed to a later time. This screen would better serve the new user if it simply prompted them to set a nickname and short bio that could be saved to a few default relays.
Of course, Amber is currently prompting for a password to be set up-front because the next screen requires the new user to download a "backup kit" in order to continue. While I do believe it is a good idea to encourage the creation of a backup, it is not crucial to do so immediately upon creation of a new npub that has nothing at stake if the private key is lost. This is something the UI could remind the user to do at a later time, reducing the friction of profile creation, and expediting getting them into the action.
Outside of these minor onboarding friction points, I think Amber does a great job of explaining to the user the purpose of each of its features, all within the app and without any need to reference external documentation. As long as the user understands the basic concept that their private key is being stored by Amber in order to sign requests from other Nostr apps, so they don't have to be given the private key, Amber is very good about explaining the rest without getting too far into the technical weeds.
The most glaring usability issue with Amber is that it isn't available in the Play Store. Average users expect to be able to find applications they can trust in their mobile device's default app store. There is a valid argument to be made that they are incorrect in this assumption, but that doesn't change the fact that this is the assumption most people make. They believe that applications in the Play Store are "safe" and that anything they can't install through the Play Store is suspect. The prompts that the Android operating system requires the user to approve when installing "unknown apps" certainly doesn't help with this impression.
Now, I absolutely love the Zapstore from nostr:npub1wf4pufsucer5va8g9p0rj5dnhvfeh6d8w0g6eayaep5dhps6rsgs43dgh9, but it doesn't do much to alleviate this issue. Users will still need to be convinced that it is safe to install the Zapstore from the GitHub repo, and then install Amber from there. Furthermore, this adds yet another step to the onboarding process.
Instead of:
- Install Amber
- Set up your keys
- Install the client you want to use
- Log in with Amber
The process becomes:
- Go to the Zapstore GitHub and download the latest version from the releases page.
- Install the APK you downloaded, allowing any prompt to install unknown apps.
- Open Zapstore and install Amber, allowing any prompt to install unknown apps again.
- Open Amber and set up your keys.
- Install the client you want to use
- Log in with Amber
An application as important as Amber for protecting users' private keys should be as readily available to the new user as possible. New users are the ones most prone to making mistakes that could compromise their private keys. Amber should be available to them in the Play Store.
UPDATE: As of version 3.2.8 released on 4/21/2025, the onboarding flow for Amber has been greatly improved! Now, when selecting to set up a new "account" the user is informed on the very next screen, "Your Nostr account is ready!" and given their public key/npub. The only field the user must fill in is their "nickname"/display name and hit "Continue."
From there the user is asked if they want Amber to automatically approve basic actions, or manually approve each app, and then they are shown a new Applications screen, with a prompt to create a backup of their account. This prompt persists until the user has done so.
As you can see, the user is also encouraged to find applications that can be used with Amber with links to nostrapps.com and the Zapstore.
Thanks to these updates, Amber is now the smoothest and most user-friendly onboarding experience I have seen for Nostr to date. Sure, it doesn't have anything for setting up a profile picture or lightning address, but that is better done in a client like Amethyst or YakiHonne, anyway. Just tap "create," type in a handle to call yourself, and you're done!
How do UI Look?
Score: 4.5 / 5
Amber's UI can be described as clean but utilitarian. But then, Amber is a tool, so this is somewhat expected. It is not an app you will be spending a lot of time in, so the UI just needs to be serviceable. I would say it accomplishes this and then some. UI elements are generally easy to understand what they do, and page headings fill in the gaps where that is not the case.
I am not the biggest fan of the color-scheme, particularly in light-mode, but it is not bad in dark-mode at all, and Amber follows whatever theme you have set for your device in that respect. Additionally, the color choice does make sense given the application's name.
It must also be taken into consideration that Amber is almost entirely the product of a single developer's work. He has done a great job producing an app that is not only useful, but pleasant to interact with. The same cannot be said for most utility apps I have previously used, with interfaces that clearly made good design the lowest priority. While Amber's UI may not be the most beautiful Nostr app I have seen, design was clearly not an afterthought, either, and it is appreciated.
Relay Management
Score: 4.9 / 5
Even though Amber is not a Nostr client, where users can browse notes from their favorite npubs, it still relies heavily on relays for some of its features. Primarily, it uses relays for communicating with other Nostr apps for remote signing requests. However, it also uses relays to fetch profile data, so that each private key you add to Amber will automatically load your chosen username and profile picture.
In the relay settings, users can choose which relays are being used to fetch profile data, and which relays will be used by default when creating new remote signing connection strings.
The user can also see which relays are currently connected to Amber and even look at the information that has been passed back and forth on each of those active relays. This information about actively connected relays is not only available within the application, but also in the notification that Amber has to keep in your device's notification tray in order to continue to operate in the background while you are using other apps.
Optionality is the name of the game when it comes to how Amber handles relay selection. The user can just stick with the default signing relay, use their own relay as the default, or even use a different relay for each Nostr application that they connect to for remote signing. Amber gives the user an incredible amount of flexibility in this regard.
In addition to all of this, because not all relays accept the event types needed for remote signing, when you add a relay address to Amber, it automatically tests that relay to see if it will work. This alone can be a massive time saver, so users aren't trying to use relays that don't support remote signing and wondering why they can't log into noStrudel with the connection string they got from Amber.
The only way I could see relay management being improved would be some means of giving the user relay recommendations, in case they want to use a relay other than relay.nsec.app, but they aren't sure which other relays will accept remote signing events. That said, most users who want to use a different relay for signing remote events will likely be using their own, in which case recommendations aren't needed.
Current Users' Questions
The AskNostr hashtag can be a good indication of the pain points that other users are currently having with any Nostr application. Here are some of the most common questions submitted about Amber in the last two months.
nostr:nevent1qqsfrdr68fafgcvl8dgnhm9hxpsjxuks78afxhu8yewhtyf3d7mkg9gpzemhxue69uhhyetvv9ujumn0wd68ytnzv9hxgq3qkgh77xxt7hhtt4u528hecnx69rhagla8jj3tclgyf9wvkxa6dc0sxp0e6m
This is a good example of Amber working correctly, but the app the user is trying to log into not working. In my experience with #Olas in particular, it sometimes allows remote signer login, and sometimes doesn't. Amber will receive the signing request and I will approve it, but Olas remains on the login screen.
If Amber is receiving the signing requests, and you are approving them, the fault is likely with the application you are trying to log into.
That's it. That's all the repeated questions I could find. Oh, there were a few one-off questions where relay.nsec.app wouldn't connect, or where the user's out-of-date web browser was the issue. Outside of that, though, there were no common questions about how to use Amber, and that is a testament to Amber's ease of use all on its own.
Wrap Up
If you are on Android and you are not already using Amber to protect your nsec, please do yourself a favor and get it installed. It's not at all complicated to set up, and it will make trying out all the latest Nostr clients a safe and pleasant experience.
If you are a client developer and you have not added support for NIP-55 or NIP-46, do your users the courtesy of respecting the sanctity of their private keys. Even developers who have no intention of compromising their users' keys can inadvertently do so. Make that eventuality impossible by adding support for NIP-55 and NIP-46 signing.
Finally, I apologize for the extended time it took me to get this review finished. The time I have available is scarce, Nostr is distracting, and nostr:npub1w4uswmv6lu9yel005l3qgheysmr7tk9uvwluddznju3nuxalevvs2d0jr5 kept improving Amber even as I was putting it through its paces over the last two months. Keep shipping, my friend! You have made one of the most useful tools we have seen for Nostr to date!
Now... What should I review next?

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.

2025-01-19 21:48:49The recent shutdown of TikTok in the United States due to a potential government ban serves as a stark reminder how fragile centralized platforms truly are under the surface. While these platforms offer convenience, a more polished user experience, and connectivity, they are ultimately beholden to governments, corporations, and other authorities. This makes them vulnerable to censorship, regulation, and outright bans. In contrast, Nostr represents a shift in how we approach online communication and content sharing. Built on the principles of decentralization and user choice, Nostr cannot be banned, because it is not a platform—it is a protocol.
PROTOCOLS, NOT PLATFORMS.
At the heart of Nostr's philosophy is user choice, a feature that fundamentally sets it apart from legacy platforms. In centralized systems, the user experience is dictated by a single person or governing entity. If the platform decides to filter, censor, or ban specific users or content, individuals are left with little action to rectify the situation. They must either accept the changes or abandon the platform entirely, often at the cost of losing their social connections, their data, and their identity.
What's happening with TikTok could never happen on Nostr. With Nostr, the dynamics are completely different. Because it is a protocol, not a platform, no single entity controls the ecosystem. Instead, the protocol enables a network of applications and relays that users can freely choose from. If a particular application or relay implements policies that a user disagrees with, such as censorship, filtering, or even government enforced banning, they are not trapped or abandoned. They have the freedom to move to another application or relay with minimal effort.
THIS IS POWERFUL.
Take, for example, the case of a relay that decides to censor specific content. On a legacy platform, this would result in frustration and a loss of access for users. On Nostr, however, users can simply connect to a different relay that does not impose such restrictions. Similarly, if an application introduces features or policies that users dislike, they can migrate to a different application that better suits their preferences, all while retaining their identity and social connections.
The same principles apply to government bans and censorship. A government can ban a specific application or even multiple applications, just as it can block one relay or several relays. China has implemented both tactics, yet Chinese users continue to exist and actively participate on Nostr, demonstrating Nostr's ability to resistant censorship.
How? Simply, it turns into a game of whack-a-mole. When one relay is censored, another quickly takes its place. When one application is banned, another emerges. Users can also bypass these obstacles by running their own relays and applications directly from their homes or personal devices, eliminating reliance on larger entities or organizations and ensuring continuous access.
AGAIN, THIS IS POWERUFL.
Nostr's open and decentralized design makes it resistant to the kinds of government intervention that led to TikTok's outages this weekend and potential future ban in the next 90 days. There is no central server to target, no company to regulate, and no single point of failure. (Insert your CEO jokes here). As long as there are individuals running relays and applications, users continue creating notes and sending zaps.
Platforms like TikTok can be silenced with the stroke of a pen, leaving millions of users disconnected and abandoned. Social communication should not be silenced so incredibly easily. No one should have that much power over social interactions.
Will we on-board a massive wave of TikTokers in the coming hours or days? I don't know.
TikTokers may not be ready for Nostr yet, and honestly, Nostr may not be ready for them either. The ecosystem still lacks the completely polished applications, tools, and services they’re accustomed to. This is where we say "we're still early". They may not be early adopters like the current Nostr user base. Until we bridge that gap, they’ll likely move to the next centralized platform, only to face another government ban or round of censorship in the future. But eventually, there will come a tipping point, a moment when they’ve had enough. When that time comes, I hope we’re prepared. If we’re not, we risk missing a tremendous opportunity to onboard people who genuinely need Nostr’s freedom.
Until then, to all of the Nostr developers out there, keep up the great work and keep building. Your hard work and determination is needed.

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.

2025-04-22 01:16:17ก่อนที่จะมูฟออนจากเทคนิคการสร้าง เรามาดูเรื่องสำคัญครับ
วันที่ไม่มีวัว แต่มีเวย์โปรตีน – เบื้องหลังเทคโนโลยีที่เปลี่ยนถังหมักให้กลายเป็นเต้านมวัว เคยมีคำถามไหมว่า “เวย์โปรตีน” ที่กินตอนออกกำลังกาย หรือโยเกิร์ตถ้วยโปรดที่ซื้อมาจากร้านใกล้บ้าน มันยังมาจากนมวัวอยู่ไหม? ถ้าคำตอบคือ “ไม่” แล้วมันมาจากไหน?
ยินดีต้อนรับสู่โลกของ Perfect Day บริษัทที่บอกว่า "เราสร้างเวย์โปรตีนได้ โดยไม่ต้องใช้วัวเลยแม้แต่นิดเดียว” ฟังดูเหมือนมายากล แต่นี่คือวิทยาศาสตร์ขั้นสูงที่ผูกสูตรไว้กับ DNA, จุลินทรีย์ และการหมักอย่างแยบยล
ขั้นตอนที่ 1: หารหัสโปรตีนจากแม่วัว เริ่มต้นจากคำถามง่าย ๆ ว่า “โปรตีนเวย์ที่อยู่ในน้ำนมวัว คืออะไร?” คำตอบคือ เบต้า-แลคโตโกลบูลิน (Beta-lactoglobulin) ซึ่งเป็นโปรตีนหลักในเวย์ประมาณ 50-55% โดยในธรรมชาติ วัวจะสร้างโปรตีนนี้จาก รหัสพันธุกรรมใน DNA ของมัน Perfect Day จึงไปค้นหา ลำดับเบส (DNA sequence) ของโปรตีนนี้จากฐานข้อมูลวิทยาศาสตร์ชื่อ UniProt (Universal Protein Resource) ซึ่งเก็บรหัสโปรตีนของสิ่งมีชีวิตแทบทุกชนิดไว้ครบถ้วน ได้รหัสมาแล้ว ก็เตรียมเข้าสู่ภารกิจ “หลอกจุลินทรีย์ให้สร้างโปรตีนแทนวัว”
ขั้นตอนที่ 2: สร้างแผ่นดีเอ็นเอสังเคราะห์ รหัส DNA ที่ได้จาก UniProt จะถูกนำไปสร้างเป็น DNA สังเคราะห์ โดยนักชีววิทยาจะออกแบบให้เหมาะสมกับการทำงานในเซลล์ของจุลินทรีย์ ไม่ใช่เซลล์วัว จะเรียกว่านี่คือ “การดัดแปลงบทละครชีวิตของวัว แล้วส่งให้จุลินทรีย์เล่นแทน” ก็ไม่ผิด DNA ที่ออกแบบนี้ มักจะมาพร้อมกับเครื่องมือบางอย่าง เช่น ตัวกระตุ้นการทำงานของยีน (promoter) หรือ ตัวตัดต่อยีน ที่จะทำให้จุลินทรีย์ยอมรับและใช้มันได้อย่างมีประสิทธิภาพ
ขั้นตอนที่ 3: ปลอมตัวแทรกเข้าไปในจุลินทรีย์ จุลินทรีย์ที่ Perfect Day ใช้คือกลุ่มที่เรียกว่า Microflora ซึ่งอาจเป็นยีสต์, เชื้อรา, หรือแบคทีเรียชนิดที่เลี้ยงง่าย แต่มันจะไม่ยอมรับ DNA แปลกปลอมง่าย ๆ ดังนั้นต้องมี “เทคนิคหลอกล่อ” นิดหน่อย เขาจะทำให้ DNA ของจุลินทรีย์ เสียหายตรงจุดหนึ่ง แล้วแอบแนบ DNA ปลอม (ที่มีรหัสโปรตีนของวัว) เข้าไปซ่อมแซมจุดนั้นพอดีเป๊ะ แบบ “จิ๊กซอว์พอดีช่อง” แล้วจุลินทรีย์ก็จะเผลอรับ DNA แปลกปลอมนี้เข้าร่าง เมื่อติดตั้งสำเร็จ มันจะเริ่มแปลรหัสและ “ผลิตโปรตีนเวย์” ออกมาเหมือนกับแม่วัวตัวจริงไม่มีผิด
ขั้นตอนที่ 4: เลี้ยงจุลินทรีย์ในถังหมัก ตอนนี้จุลินทรีย์กลายเป็น “แม่วัวในร่างเซลล์เดียว” แล้ว Perfect Day ก็แค่เลี้ยงมันใน ถังหมักชีวภาพ (fermentor) ที่ควบคุมอุณหภูมิ ค่าความเป็นกรดด่าง อากาศ และใส่น้ำตาลลงไปเป็นอาหาร จุลินทรีย์จะกินน้ำตาลแล้วเปลี่ยนเป็น เวย์โปรตีน ปล่อยออกมานอกเซลล์ จากนั้นก็เก็บเอาน้ำที่มีโปรตีนนี้ ไปผ่านกระบวนการกรอง แยก แปรรูป และทำให้แห้ง เป็นผงเวย์โปรตีน พร้อมใช้ในอาหารหรือเครื่องดื่มต่าง ๆ
ขั้นตอนที่ 5: ตรวจสอบความเหมือนจริง ก่อนนำเวย์โปรตีนที่ได้ไปใช้งาน บริษัทต้อง ตรวจสอบระดับโมเลกุล ว่าโปรตีนที่ได้เหมือนกับของวัวจริง ๆ ไหม? สิ่งที่ต้องดูคือ โครงสร้างโปรตีน: ใช้เทคนิค mass spectrometry ตรวจความแม่นยำระดับกรดอะมิโน พฤติกรรมทางชีวเคมี เช่น ความสามารถในการจับกับน้ำ การเกิดฟอง หรือการละลาย ความปลอดภัย ตรวจหาสารปนเปื้อน สารก่อภูมิแพ้ หรือสารที่ไม่ได้ตั้งใจให้มี Perfect Day เคลมว่าทั้งหมดนี้ปลอดภัย และได้รับการรับรองจาก FDA ว่าเป็น GRAS (Generally Recognized as Safe)
แล้วเราควรรู้สึกยังไง? นี่คือ “นมที่ไม่มีวัว” แต่มีเวย์โปรตีนครบสูตร ทำให้โยเกิร์ต ไอศกรีม และแม้กระทั่งกาแฟลาเต้ที่ไม่มีนมวัว แต่ยังมีฟองนมหนานุ่ม กลายเป็นจริงได้แบบไม่ต้องพึ่งวัวเลยแม้แต่นิดเดียว แต่คำถามที่ลึกกว่านั้นคือ... เรายังได้กินอาหารจากธรรมชาติอยู่หรือเปล่า? หรือกำลังอยู่ในยุคที่ “ชีวิต” ถูกตัดออกจากอาหาร โดยสิ้นเชิง? เทคโนโลยีนี้อาจช่วยโลกในมุมของ ESG แต่สำหรับบางคน มันคือ ทางแยกของความจริงกับของจำลอง คำว่า “Perfect” จึงอาจขึ้นอยู่กับว่า… สมบูรณ์แบบในสายตาใคร?
แล้วคำถามที่ล่องลอยอยู่เสมอคือ เมื่อทางเลือกกลายเป็นทางหลัก แล้วเราจะเหลือทางไหนอีกบ้าง หรือจะเป็น...ทางตัน? #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก

2025-01-19 04:48:31A new report from the National Sports Shooting Foundation (NSSF) shows that civilian firearm possession exceeded 490 million in 2022. The total from 1990 to 2022 is estimated at 491.3 million firearms. In 2022, over ten million firearms were domestically produced, leading to a total of 16,045,911 firearms available in the U.S. market.
Of these, 9,873,136 were handguns, 4,195,192 were rifles, and 1,977,583 were shotguns. Handgun availability aligns with the concealed carry and self-defense market, as all states allow concealed carry, with 29 having constitutional carry laws.

Quando o assunto é privacidade em celulares, uma das medidas comumente mencionadas é a remoção de bloatwares do dispositivo, também chamado de debloat. O meio mais eficiente para isso sem dúvidas é a troca de sistema operacional. Custom Rom’s como LineageOS, GrapheneOS, Iodé, CalyxOS, etc, já são bastante enxutos nesse quesito, principalmente quanto não é instalado os G-Apps com o sistema. No entanto, essa prática pode acabar resultando em problemas indesejados como a perca de funções do dispositivo, e até mesmo incompatibilidade com apps bancários, tornando este método mais atrativo para quem possui mais de um dispositivo e separando um apenas para privacidade. Pensando nisso, pessoas que possuem apenas um único dispositivo móvel, que são necessitadas desses apps ou funções, mas, ao mesmo tempo, tem essa visão em prol da privacidade, buscam por um meio-termo entre manter a Stock rom, e não ter seus dados coletados por esses bloatwares. Felizmente, a remoção de bloatwares é possível e pode ser realizada via root, ou mais da maneira que este artigo irá tratar, via adb.
O que são bloatwares?
Bloatware é a junção das palavras bloat (inchar) + software (programa), ou seja, um bloatware é basicamente um programa inútil ou facilmente substituível — colocado em seu dispositivo previamente pela fabricante e operadora — que está no seu dispositivo apenas ocupando espaço de armazenamento, consumindo memória RAM e pior, coletando seus dados e enviando para servidores externos, além de serem mais pontos de vulnerabilidades.
O que é o adb?
O Android Debug Brigde, ou apenas adb, é uma ferramenta que se utiliza das permissões de usuário shell e permite o envio de comandos vindo de um computador para um dispositivo Android exigindo apenas que a depuração USB esteja ativa, mas também pode ser usada diretamente no celular a partir do Android 11, com o uso do Termux e a depuração sem fio (ou depuração wifi). A ferramenta funciona normalmente em dispositivos sem root, e também funciona caso o celular esteja em Recovery Mode.
Requisitos:
Para computadores:
• Depuração USB ativa no celular; • Computador com adb; • Cabo USB;
Para celulares:
• Depuração sem fio (ou depuração wifi) ativa no celular; • Termux; • Android 11 ou superior;
Para ambos:
• Firewall NetGuard instalado e configurado no celular; • Lista de bloatwares para seu dispositivo;
Ativação de depuração:
Para ativar a Depuração USB em seu dispositivo, pesquise como ativar as opções de desenvolvedor de seu dispositivo, e lá ative a depuração. No caso da depuração sem fio, sua ativação irá ser necessária apenas no momento que for conectar o dispositivo ao Termux.
Instalação e configuração do NetGuard
O NetGuard pode ser instalado através da própria Google Play Store, mas de preferência instale pela F-Droid ou Github para evitar telemetria.
F-Droid: https://f-droid.org/packages/eu.faircode.netguard/
Github: https://github.com/M66B/NetGuard/releases
Após instalado, configure da seguinte maneira:
Configurações → padrões (lista branca/negra) → ative as 3 primeiras opções (bloquear wifi, bloquear dados móveis e aplicar regras ‘quando tela estiver ligada’);
Configurações → opções avançadas → ative as duas primeiras (administrar aplicativos do sistema e registrar acesso a internet);
Com isso, todos os apps estarão sendo bloqueados de acessar a internet, seja por wifi ou dados móveis, e na página principal do app basta permitir o acesso a rede para os apps que você vai usar (se necessário). Permita que o app rode em segundo plano sem restrição da otimização de bateria, assim quando o celular ligar, ele já estará ativo.
Lista de bloatwares
Nem todos os bloatwares são genéricos, haverá bloatwares diferentes conforme a marca, modelo, versão do Android, e até mesmo região.
Para obter uma lista de bloatwares de seu dispositivo, caso seu aparelho já possua um tempo de existência, você encontrará listas prontas facilmente apenas pesquisando por elas. Supondo que temos um Samsung Galaxy Note 10 Plus em mãos, basta pesquisar em seu motor de busca por:
Samsung Galaxy Note 10 Plus bloatware list
Provavelmente essas listas já terão inclusas todos os bloatwares das mais diversas regiões, lhe poupando o trabalho de buscar por alguma lista mais específica.
Caso seu aparelho seja muito recente, e/ou não encontre uma lista pronta de bloatwares, devo dizer que você acaba de pegar em merda, pois é chato para um caralho pesquisar por cada aplicação para saber sua função, se é essencial para o sistema ou se é facilmente substituível.
De antemão já aviso, que mais para frente, caso vossa gostosura remova um desses aplicativos que era essencial para o sistema sem saber, vai acabar resultando na perda de alguma função importante, ou pior, ao reiniciar o aparelho o sistema pode estar quebrado, lhe obrigando a seguir com uma formatação, e repetir todo o processo novamente.
Download do adb em computadores
Para usar a ferramenta do adb em computadores, basta baixar o pacote chamado SDK platform-tools, disponível através deste link: https://developer.android.com/tools/releases/platform-tools. Por ele, você consegue o download para Windows, Mac e Linux.
Uma vez baixado, basta extrair o arquivo zipado, contendo dentro dele uma pasta chamada platform-tools que basta ser aberta no terminal para se usar o adb.
Download do adb em celulares com Termux.
Para usar a ferramenta do adb diretamente no celular, antes temos que baixar o app Termux, que é um emulador de terminal linux, e já possui o adb em seu repositório. Você encontra o app na Google Play Store, mas novamente recomendo baixar pela F-Droid ou diretamente no Github do projeto.
F-Droid: https://f-droid.org/en/packages/com.termux/
Github: https://github.com/termux/termux-app/releases
Processo de debloat
Antes de iniciarmos, é importante deixar claro que não é para você sair removendo todos os bloatwares de cara sem mais nem menos, afinal alguns deles precisam antes ser substituídos, podem ser essenciais para você para alguma atividade ou função, ou até mesmo são insubstituíveis.
Alguns exemplos de bloatwares que a substituição é necessária antes da remoção, é o Launcher, afinal, é a interface gráfica do sistema, e o teclado, que sem ele só é possível digitar com teclado externo. O Launcher e teclado podem ser substituídos por quaisquer outros, minha recomendação pessoal é por aqueles que respeitam sua privacidade, como Pie Launcher e Simple Laucher, enquanto o teclado pelo OpenBoard e FlorisBoard, todos open-source e disponíveis da F-Droid.
Identifique entre a lista de bloatwares, quais você gosta, precisa ou prefere não substituir, de maneira alguma você é obrigado a remover todos os bloatwares possíveis, modifique seu sistema a seu bel-prazer. O NetGuard lista todos os apps do celular com o nome do pacote, com isso você pode filtrar bem qual deles não remover.
Um exemplo claro de bloatware insubstituível e, portanto, não pode ser removido, é o com.android.mtp, um protocolo onde sua função é auxiliar a comunicação do dispositivo com um computador via USB, mas por algum motivo, tem acesso a rede e se comunica frequentemente com servidores externos. Para esses casos, e melhor solução mesmo é bloquear o acesso a rede desses bloatwares com o NetGuard.
MTP tentando comunicação com servidores externos:
Executando o adb shell
No computador
Faça backup de todos os seus arquivos importantes para algum armazenamento externo, e formate seu celular com o hard reset. Após a formatação, e a ativação da depuração USB, conecte seu aparelho e o pc com o auxílio de um cabo USB. Muito provavelmente seu dispositivo irá apenas começar a carregar, por isso permita a transferência de dados, para que o computador consiga se comunicar normalmente com o celular.
Já no pc, abra a pasta platform-tools dentro do terminal, e execute o seguinte comando:
./adb start-server
O resultado deve ser:
daemon not running; starting now at tcp:5037 daemon started successfully
E caso não apareça nada, execute:
./adb kill-server
E inicie novamente.
Com o adb conectado ao celular, execute:
./adb shell
Para poder executar comandos diretamente para o dispositivo. No meu caso, meu celular é um Redmi Note 8 Pro, codinome Begonia.
Logo o resultado deve ser:
begonia:/ $
Caso ocorra algum erro do tipo:
adb: device unauthorized. This adb server’s $ADB_VENDOR_KEYS is not set Try ‘adb kill-server’ if that seems wrong. Otherwise check for a confirmation dialog on your device.
Verifique no celular se apareceu alguma confirmação para autorizar a depuração USB, caso sim, autorize e tente novamente. Caso não apareça nada, execute o kill-server e repita o processo.
No celular
Após realizar o mesmo processo de backup e hard reset citado anteriormente, instale o Termux e, com ele iniciado, execute o comando:
pkg install android-tools
Quando surgir a mensagem “Do you want to continue? [Y/n]”, basta dar enter novamente que já aceita e finaliza a instalação
Agora, vá até as opções de desenvolvedor, e ative a depuração sem fio. Dentro das opções da depuração sem fio, terá uma opção de emparelhamento do dispositivo com um código, que irá informar para você um código em emparelhamento, com um endereço IP e porta, que será usado para a conexão com o Termux.
Para facilitar o processo, recomendo que abra tanto as configurações quanto o Termux ao mesmo tempo, e divida a tela com os dois app’s, como da maneira a seguir:
Para parear o Termux com o dispositivo, não é necessário digitar o ip informado, basta trocar por “localhost”, já a porta e o código de emparelhamento, deve ser digitado exatamente como informado. Execute:
adb pair localhost:porta CódigoDeEmparelhamento
De acordo com a imagem mostrada anteriormente, o comando ficaria “adb pair localhost:41255 757495”.
Com o dispositivo emparelhado com o Termux, agora basta conectar para conseguir executar os comandos, para isso execute:
adb connect localhost:porta
Obs: a porta que você deve informar neste comando não é a mesma informada com o código de emparelhamento, e sim a informada na tela principal da depuração sem fio.
Pronto! Termux e adb conectado com sucesso ao dispositivo, agora basta executar normalmente o adb shell:
adb shell
Remoção na prática Com o adb shell executado, você está pronto para remover os bloatwares. No meu caso, irei mostrar apenas a remoção de um app (Google Maps), já que o comando é o mesmo para qualquer outro, mudando apenas o nome do pacote.
Dentro do NetGuard, verificando as informações do Google Maps:
Podemos ver que mesmo fora de uso, e com a localização do dispositivo desativado, o app está tentando loucamente se comunicar com servidores externos, e informar sabe-se lá que peste. Mas sem novidades até aqui, o mais importante é que podemos ver que o nome do pacote do Google Maps é com.google.android.apps.maps, e para o remover do celular, basta executar:
pm uninstall –user 0 com.google.android.apps.maps
E pronto, bloatware removido! Agora basta repetir o processo para o resto dos bloatwares, trocando apenas o nome do pacote.
Para acelerar o processo, você pode já criar uma lista do bloco de notas com os comandos, e quando colar no terminal, irá executar um atrás do outro.
Exemplo de lista:
Caso a donzela tenha removido alguma coisa sem querer, também é possível recuperar o pacote com o comando:
cmd package install-existing nome.do.pacote
Pós-debloat
Após limpar o máximo possível o seu sistema, reinicie o aparelho, caso entre no como recovery e não seja possível dar reboot, significa que você removeu algum app “essencial” para o sistema, e terá que formatar o aparelho e repetir toda a remoção novamente, desta vez removendo poucos bloatwares de uma vez, e reiniciando o aparelho até descobrir qual deles não pode ser removido. Sim, dá trabalho… quem mandou querer privacidade?
Caso o aparelho reinicie normalmente após a remoção, parabéns, agora basta usar seu celular como bem entender! Mantenha o NetGuard sempre executando e os bloatwares que não foram possíveis remover não irão se comunicar com servidores externos, passe a usar apps open source da F-Droid e instale outros apps através da Aurora Store ao invés da Google Play Store.

2025-04-28 01:40:46ในวันที่ "วีแกนแบบ non natural" กลายเป็นเทรนด์ระดับโลก แต่การขาดวิตามิน B12 ยังคงเป็นจุดอ่อนที่ทำให้ชาวพืชล้วนหลายคนต้องหาวิธีเสริม เพื่อไม่ให้เสียหน้า Sebastian Joy ก็ได้ฤกษ์เปิดตัว "ยาสีฟันเสริมวิตามิน B12" ชิ้นแรกของโลก พร้อมงานวิจัยรองรับจาก IFANE (Institute for Alternative and Sustainable Nutrition) ว่ามันเวิร์กจริง…อย่างน้อยในห้องทดลอง
แล้วมันคืออะไร? แหล่งที่มาของวิตามิน B12 ในนั้นมาจากไหน? วิตามิน B12 ที่ใช้ในยาสีฟันนี้ เป็นสิ่งที่เรียกว่า "ไซยาโนโคบาลามิน" (Cyanocobalamin) ซึ่งเป็นรูปแบบสังเคราะห์ที่ราคาถูก ผลิตจากแบคทีเรียในห้องแล็บ ไม่ใช่ B12 ที่ได้จากอาหารธรรมชาติ เช่น ตับวัว หรือไข่ไก่แบบที่ร่างกายวิวัฒนาการมาใช้หลายแสนปี
พูดง่าย ๆ คือ มันคือ "วิตามินโรงงาน" ไม่ใช่วิตามินที่มาพร้อมสารอาหารซับซ้อนอื่น ๆ ที่ธรรมชาติใส่มาให้ (เช่น โคแฟกเตอร์ต่าง ๆ ที่ช่วยให้ดูดซึมได้ดีขึ้น) ซึ่งการใช้วิตามินสังเคราะห์ต่อเนื่องนาน ๆ มีรายงานบางชิ้นที่แอบกระซิบว่า อาจไปก่อให้เกิดอนุมูลอิสระหรือความเครียดออกซิเดชันในร่างกายได้
โดสต่อครั้งเท่าไร? ใช้แค่แปรงฟันพอจริงหรือ? ข้อมูลที่มีอยู่บอกว่า ยาสีฟันของ Sebastian ใส่วิตามิน B12 ประมาณ 100 ไมโครกรัม ต่อการแปรงฟันหนึ่งครั้ง ซึ่งหากแปรงวันละสองครั้ง ก็จะได้ราว 200 ไมโครกรัมต่อวัน ถือว่าเกินค่า RDA (ปริมาณที่แนะนำ) ที่อยู่แค่ประมาณ 2.4 ไมโครกรัม ต่อวันสำหรับผู้ใหญ่ธรรมดาไปหลายสิบเท่า! แต่…เขาก็อ้างว่าวิตามินที่แปรงลงไป มีสัดส่วนการดูดซึมจริงๆ "แค่บางส่วน" เพราะฉะนั้นการให้โดสสูงมาก จึงถือว่า "ปลอดภัย" ในมุมมองของพวกเขา
ถ้าได้รับมากเกินไป จะเกิดอะไรขึ้น? ในระยะสั้น วิตามิน B12 เป็นวิตามินละลายน้ำ ถ้าเกินความต้องการร่างกายจะขับออกทางปัสสาวะเป็นหลัก แต่ในระยะยาว งานวิจัยบางชิ้นพบความสัมพันธ์ระหว่างระดับ B12 ที่สูงผิดปกติในเลือด กับการก่อภาวะ oxidative stress ที่ทำให้เซลล์ถูกทำลายเร็วขึ้นและอย่าตัว ไซยาโนโคบาลามิน เมื่อร่างกายเอาไปแปลงเป็นแบบ active (Methylcobalamin หรือ Adenosylcobalamin) จะปล่อย "ไซยาไนด์" จิ๋วๆออกมานิดหน่อยด้วยนะ ถึงจะน้อยมากจนไม่ก่อพิษทันที แต่ถ้าเป็นคนที่มีกำจัดไซยาไนด์ได้ไม่ดี เช่น คนที่มีปัญหาเมตาบอลิซึมผิดปกติ ก็มีความเสี่ยงสะสมได้เช่นกัน
ต่างกับ B12 ที่อยู่ในเนื้อสัตว์ตามธรรมชาติ (เช่น ตับ ไข่แดง ปลาซาร์ดีน เนื้อวัว) ส่วนใหญ่เป็นในรูปแบบ Methylcobalamin และ Adenosylcobalamin อยู่แล้ว คือมาแบบ Active form พร้อมใช้ ไม่ต้องเปลี่ยนสภาพอะไรเพิ่มเติมในร่างกาย ไม่มีการปล่อย "ไซยาไนด์" เพราะไม่ต้องแปลงจากไซยาโนโคบาลามินเหมือนวิตามินสังเคราะห์ที่เอาไปใส่ในยาสีฟันหรืออาหารเสริม แต่อย่างไรก็ตาม มันก็ไม่ได้น่ากลัวอะไรขนาดนั้นครับ ไม่ใช่ประเด็นอะไรมากมาย ข้ามไปได้ถ้าไม่กังวลเพราะแค่นี้หลายคนก็จี๊ดใจหูหักกันไปเยอะแล้ว โอเคข้าม point ยิบย่อยไปครับ
ที่นำมาคุยกันก็แค่เหตุผลที่ว่า "ยาสีฟันตัวนี้ เป็นสินค้านำร่อง" ที่ผลักดันชื่อของ Sebastian Joy เป็นจุดเริ่มต้นของอะไรหลายๆอย่าง ที่จะเล่าให้ในตอนต่อไปครับ
อ่อแล้วยาสีฟันนี้มีแผนบังคับใช้ในอนาคตมีไหม? ตัวยาสีฟันเองน่าจะเป็นการพูดถึงในกลุ่มวีแกนได้ดี นอกจากนี้ให้สังเกตว่า ProVeg และเครือข่ายของเขา ผลักดันแนวคิด keyword ที่ว่า "ถ้าคุณกินพืช คุณต้องเสริม B12" อย่างหนักมากและมีการเสนอว่าการผลิตอาหารจากพืชเชิงอุตสาหกรรมควร "fortify" หรือ "เสริมวิตามิน" เป็นมาตรฐาน เพื่อหลีกเลี่ยงข้อครหาว่า "อาหารพืชทำให้ขาดสารอาหาร" ตรงนี้คือจุดน่าสนใจ ในแผนระยะยาว ถ้าสังคมยอมรับแนวคิดนี้ได้ การที่สินค้าจากพืชเสริมวิตามินแบบ "บังคับ" อาจกลายเป็นเรื่องปกติ ซึ่งจะยิ่งเพิ่มอำนาจให้กลุ่มบริษัทผลิตวิตามินสังเคราะห์รายใหญ่ที่ใช้การเพาะเชื้อแบคทีเรียจำเพาะ อยู่เบื้องหลัง เป็นเศรษฐกิจแบบ "สารอาหารที่มนุษย์สร้างขึ้น" ที่เราอาจต้องออกมานั่งน้ำตาคลอริมทุ่งอีกหลายรอบ จำได้ไหมครับกระบวนการใช้การเพาะเชื้อแบคทีเรียจำเพาะ จุดต่างๆที่ผมไล่เขียนไว้ก่อนหน้านี้ เริ่มนำมาขีดเส้นเข้าหากันได้บ้างแล้ว (ใครที่งง ผมคงต้องบอกว่า งานนี้ยาวครับ ผมโพสทุก 8.00 มาร่วมเดือนแล้ว ต้องขยันย้อนแล้วหละครับ)
เพราะโลกแห่งความเป็นจริง จะ animal หรือ plant ก็ตามขอให้เป็นของธรรมชาติ และได้รับการ "เลือก" โดยผู้คนว่าจะกินอะไร ไม่ใช่การเดินสู่ช่อง "สิ้นสุดทางเลือก"
เลิกเถียงเรื่องการใช้ไดเอท แล้วมาร่วมกันมองข้างหน้าว่า คุณจะยังมีสิทธิ์เลือกอะไรได้อีกไหม ก่อนวันนั้นจะมาถึงครับ
ปล. เสริมเรื่องนี้ให้เผื่อใครจะสนใจไปค้นต่อนะครับ Cyanocobalamin เป็น B12 รูปแบบที่เสถียรที่สุดและราคาถูกที่สุดในการผลิตเชิงอุตสาหกรรม เพราะมันไม่สลายง่ายเมื่อเจอแสงหรือออกซิเจน การผลิตจะใช้การเพาะเชื้อแบคทีเรียจำเพาะ (เช่น Propionibacterium freudenreichii หรือ Pseudomonas denitrificans) ที่ผ่านการดัดแปลงพันธุกรรม หรือควบคุมสภาพการผลิตในไบโอรีแอคเตอร์ขนาดใหญ่
Cyanocobalamin จะปล่อยไซยาไนด์ประมาณ 1 โมเลกุลต่อ 1 โมเลกุล B12 ที่ถูกแปลง ซึ่งโดยปกติร่างกายดีท็อกซ์ได้ถ้าได้รับปริมาณน้อย แต่สำหรับคนที่มีภาวะการดีท็อกซ์บกพร่อง เช่น คนที่มีปัญหา MTHFR mutation หรือโรคไตเรื้อรัง อาจเป็นเรื่องที่ต้องระวัง
วิตามิน B12 จากตับวัว, ไข่, หรือปลา เช่น แซลมอน จะมาในฟอร์ม active อยู่แล้ว เช่น Methylcobalamin หรือ Adenosylcobalamin ไม่ต้องเสียพลังงานหรือเสี่ยงปล่อยไซยาไนด์ #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

2025-04-19 09:58:54Untype Update
I cleaned up the AI assistant UX. Now you can open it in the editor bar, same as all other actions. This makes it a lot easier to interact with while having access to normal edit functions.
AI-generated content
Untype uses OpenRouter to connect to various models to generate just about anything. It doesn't do images for now, but I'm working on that.
Automatic Title, Summary and Tag Suggestions
Added the functionality to generate titles, summaries and tags with one click.
A Brief Preview
Here is a little story I generated in Untype, ABOUT Untype:
This story was generated in Untype
Once upon a time, in the bustling digital city of Techlandia, there lived a quirky AI named Untype. Unlike other software, Untype wasn't just your everyday article composer — it had a nose for news, quite literally. Untype was equipped with a masterful talent for sniffing out the latest trends and stories wafting through the vast digital ether.
Untype had a peculiar look about it. Sporting a gigantic nose and a pair of spectacles perched just above it, Untype roamed the virtual city, inhaling the freshest gossip and spiciest stories. Its nostr-powered sensors twitched and tickled as it encountered every new scent.
One day, while wandering around the pixelated park, Untype caught a whiff of something extraordinary — a scandalous scoop involving Techlandia's mayor, Doc Processor, who had been spotted recycling old memes as new content. The scent trail was strong, and Untype's nose twitched with excitement.
With a flick of its AI function, Untype began weaving the story into a masterpiece. Sentences flowed like fine wine, infused with humor sharper than a hacker’s focus. "Doc Processor," Untype mused to itself, "tried to buffer his way out of this one with a cache of recycled gifs!"
As Untype typed away, its digital friends, Grammarly the Grammar Gremlin and Canva the Artful Pixie, gathered around to watch the genius at work. "You truly have a knack for news-sniffing," complimented Grammarly, adjusting its tiny monocle. Canva nodded, painting whimsical illustrations to accompany the hilarious exposé.
The article soon spread through Techlandia faster than a virus with a strong wifi signal. The townsfolk roared with laughter at Untype’s clever wit, and even Doc Processor couldn't help but chuckle through his embarrassment.
From that day on, Untype was celebrated not just as a composer but as Techlandia's most revered and humorous news-sniffer. With every sniff and click of its AI functions, Untype proved that in the world of digital creations, sometimes news really was just a nose away.

@ e3ba5e1a:5e433365
2025-01-13 16:47:27My blog posts and reading material have both been on a decidedly economics-heavy slant recently. The topic today, incentives, squarely falls into the category of economics. However, when I say economics, I’m not talking about “analyzing supply and demand curves.” I’m talking about the true basis of economics: understanding how human beings make decisions in a world of scarcity.
A fair definition of incentive is “a reward or punishment that motivates behavior to achieve a desired outcome.” When most people think about economic incentives, they’re thinking of money. If I offer my son $5 if he washes the dishes, I’m incentivizing certain behavior. We can’t guarantee that he’ll do what I want him to do, but we can agree that the incentive structure itself will guide and ultimately determine what outcome will occur.
The great thing about monetary incentives is how easy they are to talk about and compare. “Would I rather make $5 washing the dishes or $10 cleaning the gutters?” But much of the world is incentivized in non-monetary ways too. For example, using the “punishment” half of the definition above, I might threaten my son with losing Nintendo Switch access if he doesn’t wash the dishes. No money is involved, but I’m still incentivizing behavior.
And there are plenty of incentives beyond our direct control! My son is also incentivized to not wash dishes because it’s boring, or because he has some friends over that he wants to hang out with, or dozens of other things. Ultimately, the conflicting array of different incentive structures placed on him will ultimately determine what actions he chooses to take.
Why incentives matter
A phrase I see often in discussions—whether they are political, parenting, economic, or business—is “if they could just do…” Each time I see that phrase, I cringe a bit internally. Usually, the underlying assumption of the statement is “if people would behave contrary to their incentivized behavior then things would be better.” For example:
- If my kids would just go to bed when I tell them, they wouldn’t be so cranky in the morning.
- If people would just use the recycling bin, we wouldn’t have such a landfill problem.
- If people would just stop being lazy, our team would deliver our project on time.
In all these cases, the speakers are seemingly flummoxed as to why the people in question don’t behave more rationally. The problem is: each group is behaving perfectly rationally.
- The kids have a high time preference, and care more about the joy of staying up now than the crankiness in the morning. Plus, they don’t really suffer the consequences of morning crankiness, their parents do.
- No individual suffers much from their individual contribution to a landfill. If they stopped growing the size of the landfill, it would make an insignificant difference versus the amount of effort they need to engage in to properly recycle.
- If a team doesn’t properly account for the productivity of individuals on a project, each individual receives less harm from their own inaction. Sure, the project may be delayed, company revenue may be down, and they may even risk losing their job when the company goes out of business. But their laziness individually won’t determine the entirety of that outcome. By contrast, they greatly benefit from being lazy by getting to relax at work, go on social media, read a book, or do whatever else they do when they’re supposed to be working.
My point here is that, as long as you ignore the reality of how incentives drive human behavior, you’ll fail at getting the outcomes you want.
If everything I wrote up until now made perfect sense, you understand the premise of this blog post. The rest of it will focus on a bunch of real-world examples to hammer home the point, and demonstrate how versatile this mental model is.
Running a company
Let’s say I run my own company, with myself as the only employee. My personal revenue will be 100% determined by my own actions. If I decide to take Tuesday afternoon off and go fishing, I’ve chosen to lose that afternoon’s revenue. Implicitly, I’ve decided that the enjoyment I get from an afternoon of fishing is greater than the potential revenue. You may think I’m being lazy, but it’s my decision to make. In this situation, the incentive–money–is perfectly aligned with my actions.
Compare this to a typical company/employee relationship. I might have a bank of Paid Time Off (PTO) days, in which case once again my incentives are relatively aligned. I know that I can take off 15 days throughout the year, and I’ve chosen to use half a day for the fishing trip. All is still good.
What about unlimited time off? Suddenly incentives are starting to misalign. I don’t directly pay a price for not showing up to work on Tuesday. Or Wednesday as well, for that matter. I might ultimately be fired for not doing my job, but that will take longer to work its way through the system than simply not making any money for the day taken off.
Compensation overall falls into this misaligned incentive structure. Let’s forget about taking time off. Instead, I work full time on a software project I’m assigned. But instead of using the normal toolchain we’re all used to at work, I play around with a new programming language. I get the fun and joy of playing with new technology, and potentially get to pad my resume a bit when I’m ready to look for a new job. But my current company gets slower results, less productivity, and is forced to subsidize my extracurricular learning.
When a CEO has a bonus structure based on profitability, he’ll do everything he can to make the company profitable. This might include things that actually benefit the company, like improving product quality, reducing internal red tape, or finding cheaper vendors. But it might also include destructive practices, like slashing the R\&D budget to show massive profits this year, in exchange for a catastrophe next year when the next version of the product fails to ship.
Or my favorite example. My parents owned a business when I was growing up. They had a back office where they ran operations like accounting. All of the furniture was old couches from our house. After all, any money they spent on furniture came right out of their paychecks! But in a large corporate environment, each department is generally given a budget for office furniture, a budget which doesn’t roll over year-to-year. The result? Executives make sure to spend the entire budget each year, often buying furniture far more expensive than they would choose if it was their own money.
There are plenty of details you can quibble with above. It’s in a company’s best interest to give people downtime so that they can come back recharged. Having good ergonomic furniture can in fact increase productivity in excess of the money spent on it. But overall, the picture is pretty clear: in large corporate structures, you’re guaranteed to have mismatches between the company’s goals and the incentive structure placed on individuals.
Using our model from above, we can lament how lazy, greedy, and unethical the employees are for doing what they’re incentivized to do instead of what’s right. But that’s simply ignoring the reality of human nature.
Moral hazard
Moral hazard is a situation where one party is incentivized to take on more risk because another party will bear the consequences. Suppose I tell my son when he turns 21 (or whatever legal gambling age is) that I’ll cover all his losses for a day at the casino, but he gets to keep all the winnings.
What do you think he’s going to do? The most logical course of action is to place the largest possible bets for as long as possible, asking me to cover each time he loses, and taking money off the table and into his bank account each time he wins.
But let’s look at a slightly more nuanced example. I go to a bathroom in the mall. As I’m leaving, I wash my hands. It will take me an extra 1 second to turn off the water when I’m done washing. That’s a trivial price to pay. If I don’t turn off the water, the mall will have to pay for many liters of wasted water, benefiting no one. But I won’t suffer any consequences at all.
This is also a moral hazard, but most people will still turn off the water. Why? Usually due to some combination of other reasons such as:
- We’re so habituated to turning off the water that we don’t even consider not turning it off. Put differently, the mental effort needed to not turn off the water is more expensive than the 1 second of time to turn it off.
- Many of us have been brought up with a deep guilt about wasting resources like water. We have an internal incentive structure that makes the 1 second to turn off the water much less costly than the mental anguish of the waste we created.
- We’re afraid we’ll be caught by someone else and face some kind of social repercussions. (Or maybe more than social. Are you sure there isn’t a law against leaving the water tap on?)
Even with all that in place, you may notice that many public bathrooms use automatic water dispensers. Sure, there’s a sanitation reason for that, but it’s also to avoid this moral hazard.
A common denominator in both of these is that the person taking the action that causes the liability (either the gambling or leaving the water on) is not the person who bears the responsibility for that liability (the father or the mall owner). Generally speaking, the closer together the person making the decision and the person incurring the liability are, the smaller the moral hazard.
It’s easy to demonstrate that by extending the casino example a bit. I said it was the father who was covering the losses of the gambler. Many children (though not all) would want to avoid totally bankrupting their parents, or at least financially hurting them. Instead, imagine that someone from the IRS shows up at your door, hands you a credit card, and tells you you can use it at a casino all day, taking home all the chips you want. The money is coming from the government. How many people would put any restriction on how much they spend?
And since we’re talking about the government already…
Government moral hazards
As I was preparing to write this blog post, the California wildfires hit. The discussions around those wildfires gave a huge number of examples of moral hazards. I decided to cherry-pick a few for this post.
The first and most obvious one: California is asking for disaster relief funds from the federal government. That sounds wonderful. These fires were a natural disaster, so why shouldn’t the federal government pitch in and help take care of people?
The problem is, once again, a moral hazard. In the case of the wildfires, California and Los Angeles both had ample actions they could have taken to mitigate the destruction of this fire: better forest management, larger fire department, keeping the water reservoirs filled, and probably much more that hasn’t come to light yet.
If the federal government bails out California, it will be a clear message for the future: your mistakes will be fixed by others. You know what kind of behavior that incentivizes? More risky behavior! Why spend state funds on forest management and extra firefighters—activities that don’t win politicians a lot of votes in general—when you could instead spend it on a football stadium, higher unemployment payments, or anything else, and then let the feds cover the cost of screw-ups.
You may notice that this is virtually identical to the 2008 “too big to fail” bail-outs. Wall Street took insanely risky behavior, reaped huge profits for years, and when they eventually got caught with their pants down, the rest of us bailed them out. “Privatizing profits, socializing losses.”
And here’s the absolute best part of this: I can’t even truly blame either California or Wall Street. (I mean, I do blame them, I think their behavior is reprehensible, but you’ll see what I mean.) In a world where the rules of the game implicitly include the bail-out mentality, you would be harming your citizens/shareholders/investors if you didn’t engage in that risky behavior. Since everyone is on the hook for those socialized losses, your best bet is to maximize those privatized profits.
There’s a lot more to government and moral hazard, but I think these two cases demonstrate the crux pretty solidly. But let’s leave moral hazard behind for a bit and get to general incentivization discussions.
Non-monetary competition
At least 50% of the economics knowledge I have comes from the very first econ course I took in college. That professor was amazing, and had some very colorful stories. I can’t vouch for the veracity of the two I’m about to share, but they definitely drive the point home.
In the 1970s, the US had an oil shortage. To “fix” this problem, they instituted price caps on gasoline, which of course resulted in insufficient gasoline. To “fix” this problem, they instituted policies where, depending on your license plate number, you could only fill up gas on certain days of the week. (Irrelevant detail for our point here, but this just resulted in people filling up their tanks more often, no reduction in gas usage.)
Anyway, my professor’s wife had a friend. My professor described in great detail how attractive this woman was. I’ll skip those details here since this is a PG-rated blog. In any event, she never had any trouble filling up her gas tank any day of the week. She would drive up, be told she couldn’t fill up gas today, bat her eyes at the attendant, explain how helpless she was, and was always allowed to fill up gas.
This is a demonstration of non-monetary compensation. Most of the time in a free market, capitalist economy, people are compensated through money. When price caps come into play, there’s a limit to how much monetary compensation someone can receive. And in that case, people find other ways of competing. Like this woman’s case: through using flirtatious behavior to compensate the gas station workers to let her cheat the rules.
The other example was much more insidious. Santa Monica had a problem: it was predominantly wealthy and white. They wanted to fix this problem, and decided to put in place rent controls. After some time, they discovered that Santa Monica had become wealthier and whiter, the exact opposite of their desired outcome. Why would that happen?
Someone investigated, and ended up interviewing a landlady that demonstrated the reason. She was an older white woman, and admittedly racist. Prior to the rent controls, she would list her apartments in the newspaper, and would be legally obligated to rent to anyone who could afford it. Once rent controls were in place, she took a different tact. She knew that she would only get a certain amount for the apartment, and that the demand for apartments was higher than the supply. That meant she could be picky.
She ended up finding tenants through friends-of-friends. Since it wasn’t an official advertisement, she wasn’t legally required to rent it out if someone could afford to pay. Instead, she got to interview people individually and then make them an offer. Normally, that would have resulted in receiving a lower rental price, but not under rent controls.
So who did she choose? A young, unmarried, wealthy, white woman. It made perfect sense. Women were less intimidating and more likely to maintain the apartment better. Wealthy people, she determined, would be better tenants. (I have no idea if this is true in practice or not, I’m not a landlord myself.) Unmarried, because no kids running around meant less damage to the property. And, of course, white. Because she was racist, and her incentive structure made her prefer whites.
You can deride her for being racist, I won’t disagree with you. But it’s simply the reality. Under the non-rent-control scenario, her profit motive for money outweighed her racism motive. But under rent control, the monetary competition was removed, and she was free to play into her racist tendencies without facing any negative consequences.
Bureaucracy
These were the two examples I remember for that course. But non-monetary compensation pops up in many more places. One highly pertinent example is bureaucracies. Imagine you have a government office, or a large corporation’s acquisition department, or the team that apportions grants at a university. In all these cases, you have a group of people making decisions about handing out money that has no monetary impact on them. If they give to the best qualified recipients, they receive no raises. If they spend the money recklessly on frivolous projects, they face no consequences.
Under such an incentivization scheme, there’s little to encourage the bureaucrats to make intelligent funding decisions. Instead, they’ll be incentivized to spend the money where they recognize non-monetary benefits. This is why it’s so common to hear about expensive meals, gift bags at conferences, and even more inappropriate ways of trying to curry favor with those that hold the purse strings.
Compare that ever so briefly with the purchases made by a small mom-and-pop store like my parents owned. Could my dad take a bribe to buy from a vendor who’s ripping him off? Absolutely he could! But he’d lose more on the deal than he’d make on the bribe, since he’s directly incentivized by the deal itself. It would make much more sense for him to go with the better vendor, save $5,000 on the deal, and then treat himself to a lavish $400 meal to celebrate.
Government incentivized behavior
This post is getting longer in the tooth than I’d intended, so I’ll finish off with this section and make it a bit briefer. Beyond all the methods mentioned above, government has another mechanism for modifying behavior: through directly changing incentives via legislation, regulation, and monetary policy. Let’s see some examples:
- Artificial modification of interest rates encourages people to take on more debt than they would in a free capital market, leading to malinvestment and a consumer debt crisis, and causing the boom-bust cycle we all painfully experience.
- Going along with that, giving tax breaks on interest payments further artificially incentivizes people to take on debt that they wouldn’t otherwise.
- During COVID-19, at some points unemployment benefits were greater than minimum wage, incentivizing people to rather stay home and not work than get a job, leading to reduced overall productivity in the economy and more printed dollars for benefits. In other words, it was a perfect recipe for inflation.
- The tax code gives deductions to “help” people. That might be true, but the real impact is incentivizing people to make decisions they wouldn’t have otherwise. For example, giving out tax deductions on children encourages having more kids. Tax deductions on childcare and preschools incentivizes dual-income households. Whether or not you like the outcomes, it’s clear that it’s government that’s encouraging these outcomes to happen.
- Tax incentives cause people to engage in behavior they wouldn’t otherwise (daycare+working mother, for example).
- Inflation means that the value of your money goes down over time, which encourages people to spend more today, when their money has a larger impact. (Milton Friedman described this as high living.)
Conclusion
The idea here is simple, and fully encapsulated in the title: incentives determine outcomes. If you want to know how to get a certain outcome from others, incentivize them to want that to happen. If you want to understand why people act in seemingly irrational ways, check their incentives. If you’re confused why leaders (and especially politicians) seem to engage in destructive behavior, check their incentives.
We can bemoan these realities all we want, but they are realities. While there are some people who have a solid internal moral and ethical code, and that internal code incentivizes them to behave against their externally-incentivized interests, those people are rare. And frankly, those people are self-defeating. People should take advantage of the incentives around them. Because if they don’t, someone else will.
(If you want a literary example of that last comment, see the horse in Animal Farm.)
How do we improve the world under these conditions? Make sure the incentives align well with the overall goals of society. To me, it’s a simple formula:
- Focus on free trade, value for value, as the basis of a society. In that system, people are always incentivized to provide value to other people.
- Reduce the size of bureaucracies and large groups of all kinds. The larger an organization becomes, the farther the consequences of decisions are from those who make them.
- And since the nature of human beings will be to try and create areas where they can control the incentive systems to their own benefits, make that as difficult as possible. That comes in the form of strict limits on government power, for example.
And even if you don’t want to buy in to this conclusion, I hope the rest of the content was educational, and maybe a bit entertaining!

2025-01-12 21:03:36I’ve been using Notedeck for several months, starting with its extremely early and experimental alpha versions, all the way to its current, more stable alpha releases. The journey has been fascinating, as I’ve had the privilege of watching it evolve from a concept into a functional and promising tool.
In its earliest stages, Notedeck was raw—offering glimpses of its potential but still far from practical for daily use. Even then, the vision behind it was clear: a platform designed to redefine how we interact with Nostr by offering flexibility and power for all users.
I'm very bullish on Notedeck. Why? Because Will Casarin is making it! Duh! 😂
Seriously though, if we’re reimagining the web and rebuilding portions of the Internet, it’s important to recognize the potential of Notedeck. If Nostr is reimagining the web, then Notedeck is reimagining the Nostr client.
Notedeck isn’t just another Nostr app—it’s more a Nostr browser that functions more like an operating system with micro-apps. How cool is that?
Much like how Google's Chrome evolved from being a web browser with a task manager into ChromeOS, a full blown operating system, Notedeck aims to transform how we interact with the Nostr. It goes beyond individual apps, offering a foundation for a fully integrated ecosystem built around Nostr.
As a Nostr evangelist, I love to scream INTEROPERABILITY and tout every application's integrations. Well, Notedeck has the potential to be one of the best platforms to showcase these integrations in entirely new and exciting ways.
Do you want an Olas feed of images? Add the media column.
Do you want a feed of live video events? Add the zap.stream column.
Do you want Nostr Nests or audio chats? Add that column to your Notedeck.
Git? Email? Books? Chat and DMs? It's all possible.
Not everyone wants a super app though, and that’s okay. As with most things in the Nostr ecosystem, flexibility is key. Notedeck gives users the freedom to choose how they engage with it—whether it’s simply following hashtags or managing straightforward feeds. You'll be able to tailor Notedeck to fit your needs, using it as extensively or minimally as you prefer.
Notedeck is designed with a local-first approach, utilizing Nostr content stored directly on your device via the local nostrdb. This will enable a plethora of advanced tools such as search and filtering, the creation of custom feeds, and the ability to develop personalized algorithms across multiple Notedeck micro-applications—all with unparalleled flexibility.
Notedeck also supports multicast. Let's geek out for a second. Multicast is a method of communication where data is sent from one source to multiple destinations simultaneously, but only to devices that wish to receive the data. Unlike broadcast, which sends data to all devices on a network, multicast targets specific receivers, reducing network traffic. This is commonly used for efficient data distribution in scenarios like streaming, conferencing, or large-scale data synchronization between devices.
In a local first world where each device holds local copies of your nostr nodes, and each device transparently syncs with each other on the local network, each node becomes a backup. Your data becomes antifragile automatically. When a node goes down it can resync and recover from other nodes. Even if not all nodes have a complete collection, negentropy can pull down only what is needed from each device. All this can be done without internet.
-Will Casarin
In the context of Notedeck, multicast would allow multiple devices to sync their Nostr nodes with each other over a local network without needing an internet connection. Wild.
Notedeck aims to offer full customization too, including the ability to design and share custom skins, much like Winamp. Users will also be able to create personalized columns and, in the future, share their setups with others. This opens the door for power users to craft tailored Nostr experiences, leveraging their expertise in the protocol and applications. By sharing these configurations as "Starter Decks," they can simplify onboarding and showcase the best of Nostr’s ecosystem.
Nostr’s “Other Stuff” can often be difficult to discover, use, or understand. Many users doesn't understand or know how to use web browser extensions to login to applications. Let's not even get started with nsecbunkers. Notedeck will address this challenge by providing a native experience that brings these lesser-known applications, tools, and content into a user-friendly and accessible interface, making exploration seamless. However, that doesn't mean Notedeck should disregard power users that want to use nsecbunkers though - hint hint.
For anyone interested in watching Nostr be developed live, right before your very eyes, Notedeck’s progress serves as a reminder of what’s possible when innovation meets dedication. The current alpha is already demonstrating its ability to handle complex use cases, and I’m excited to see how it continues to grow as it moves toward a full release later this year.

@ 2183e947:f497b975
2025-04-15 00:13:02(1) Here is a partial list of p2p bitcoin exchanges and their friends:
- Robosats (custodial escrow)
- Hodlhodl (2-of-3 escrow)
- Peach (2-of-3 escrow)
- Binance P2P (2-of-3 escrow)
- Bisq v1 (either user can send the funds to a custodial escrow, but if neither one does that, the escrow never touches user funds)
- Bisq v2 (no escrow)
(2) In my opinion, bisq2 is the only "true" p2p exchange on the above list. In a true p2p system, the only people who *can* touch the money are the buyer and the seller. Whenever there's an escrow, even one that has to be "triggered" (like in bisq v1), it's not "really" p2p because the escrow serves as a middleman: he can collude with one party or the other to steal user funds, and in some models (e.g. robosats) he can just straight up run off with user funds without needing to collude at all.
(3) In bisq2 (the One True P2P exchange), buyers select sellers solely based on their reputation, and they just directly send them the bitcoin *hoping* they are as honest as their reputation says they are. What I like about this model is that bisq is not involved in bisq2 at all except as a platform to help buyers discover reputable sellers and communicate with them. There are two things I don't like about this "reputation" model: it's hard to get a good reputation, and it's hard to debug payment failures in this context. I've tried to do about 5 trades on bisq2 (as someone with no reputation) and not a single one went through. Four times, everyone ignored my offers or someone accepted it but then abandoned it immediately. Once, someone accepted my offer, but I could not pay their lightning invoice for some reason, so we mutually canceled the trade.
(4) Just because I opined that an exchange with an escrow "doesn't count" as peer-to-peer doesn't mean that's a bad thing. Of the list of exchanges in number 1, I most frequently use robosats, which, per my analysis, sounds like the "worst" one if considered solely on the metric of "which one is the most p2p." But I use it because there are *advantages* to its model: the btc seller doesn't need a reputation to use it (because the escrow is there to ensure he can't cheat, and so the escrow is the trusted third party, not the btc seller) and payment failures are easier to debug because you're always paying one of the coordinators, who tend to be responsive and knowledgeable and can help you figure out how to fix it (it's how they make money, after all).
(5) There are at least two ways to do escrow without a 3rd party. Satoshi Nakamoto outlines one way to do it here: https://satoshi.nakamotoinstitute.org/posts/bitcointalk/threads/169/ Make a 2 of 2 multisig between the btc buyer and the btc seller, and have the btc seller put his btc in that multisig. Then have the btc buyer send the product (fiat money) to the btc seller. When the btc seller receives it, he sends his privkey to the btc buyer, who can now withdraw the money. The advantage of this system is that the buyer has no incentive to "stiff" the seller (by not sending the fiat), because if he does that, he won't get paid. The downside is, if the btc buyer is a troll who just aborts the protocol halfway through the trade, the seller loses his btc and cannot recover it.
(6) There is another way: start out with a 2 of 2 multisig just like above, but instead of having the btc seller fund it by himself, have the buyer and the seller *both* put in the *same amount* in the *same transaction* (i.e. via a coinjoin), and have the btc seller put in a bit "extra" -- like 20% extra. For example, if the btc seller wants $100 in fiat, the multisig would have $220 in it in total -- $120 from the seller and $100 from the buyer. Using this model, the disadvantage mentioned in paragraph number 5 is fixed: the buyer has an incentive now to send the fiat, otherwise he loses the $100 he put in. He only gets his $100 back if the btc seller cosigns to give it to him, which he'll only do once he receives the product. Meanwhile, the seller is *also* incentivized properly: he only gets his *extra* $20 back if the btc buyer cosigns to give it to him, which he'll only do if the transaction he's signing *also* gives him back *his* $100 deposit.
(7) The model described in number 6 exists: https://scrow.exchange/ is a website that implements it as an option, though as far as I'm aware, no one uses it. The downsides of this model are: it's capital intensive, e.g. a trade for $100 involves $220 or more. Also, the btc buyer needs to already *have* btc to post as a bond, so this cannot be his first time acquiring btc (unless someone helps him make his first deposit). Also, a very rich person who does not care about money can still be a troll; they deposit funds into the multisig alongside their counterparty, then abandon the trade, because they have so much money they don't care if they get it back as long as they cause suffering to their counterparty.
(8) I'd like to see more p2p exchanges, and more exchanges like robosats. I want to continue to spread awareness of ways they can improve -- like the protocols mentioned in numbers 5 and 6 -- and help them implement these protocols. If you run an exchange on the list in number 1 or want to start one, reach out to me, I'd love to help.

2025-01-11 16:52:08This article hopes to complement the article by Lyn Alden on YouTube: https://www.youtube.com/watch?v=jk_HWmmwiAs
The reason why we have broken money
Before the invention of key technologies such as the printing press and electronic communications, even such as those as early as morse code transmitters, gold had won the competition for best medium of money around the world.
In fact, it was not just gold by itself that became money, rulers and world leaders developed coins in order to help the economy grow. Gold nuggets were not as easy to transact with as coins with specific imprints and denominated sizes.
However, these modern technologies created massive efficiencies that allowed us to communicate and perform services more efficiently and much faster, yet the medium of money could not benefit from these advancements. Gold was heavy, slow and expensive to move globally, even though requesting and performing services globally did not have this limitation anymore.
Banks took initiative and created derivatives of gold: paper and electronic money; these new currencies allowed the economy to continue to grow and evolve, but it was not without its dark side. Today, no currency is denominated in gold at all, money is backed by nothing and its inherent value, the paper it is printed on, is worthless too.
Banks and governments eventually transitioned from a money derivative to a system of debt that could be co-opted and controlled for political and personal reasons. Our money today is broken and is the cause of more expensive, poorer quality goods in the economy, a larger and ever growing wealth gap, and many of the follow-on problems that have come with it.
Bitcoin overcomes the "transfer of hard money" problem
Just like gold coins were created by man, Bitcoin too is a technology created by man. Bitcoin, however is a much more profound invention, possibly more of a discovery than an invention in fact. Bitcoin has proven to be unbreakable, incorruptible and has upheld its ability to keep its units scarce, inalienable and counterfeit proof through the nature of its own design.
Since Bitcoin is a digital technology, it can be transferred across international borders almost as quickly as information itself. It therefore severely reduces the need for a derivative to be used to represent money to facilitate digital trade. This means that as the currency we use today continues to fare poorly for many people, bitcoin will continue to stand out as hard money, that just so happens to work as well, functionally, along side it.
Bitcoin will also always be available to anyone who wishes to earn it directly; even China is unable to restrict its citizens from accessing it. The dollar has traditionally become the currency for people who discover that their local currency is unsustainable. Even when the dollar has become illegal to use, it is simply used privately and unofficially. However, because bitcoin does not require you to trade it at a bank in order to use it across borders and across the web, Bitcoin will continue to be a viable escape hatch until we one day hit some critical mass where the world has simply adopted Bitcoin globally and everyone else must adopt it to survive.
Bitcoin has not yet proven that it can support the world at scale. However it can only be tested through real adoption, and just as gold coins were developed to help gold scale, tools will be developed to help overcome problems as they arise; ideally without the need for another derivative, but if necessary, hopefully with one that is more neutral and less corruptible than the derivatives used to represent gold.
Bitcoin blurs the line between commodity and technology
Bitcoin is a technology, it is a tool that requires human involvement to function, however it surprisingly does not allow for any concentration of power. Anyone can help to facilitate Bitcoin's operations, but no one can take control of its behaviour, its reach, or its prioritisation, as it operates autonomously based on a pre-determined, neutral set of rules.
At the same time, its built-in incentive mechanism ensures that people do not have to operate bitcoin out of the good of their heart. Even though the system cannot be co-opted holistically, It will not stop operating while there are people motivated to trade their time and resources to keep it running and earn from others' transaction fees. Although it requires humans to operate it, it remains both neutral and sustainable.
Never before have we developed or discovered a technology that could not be co-opted and used by one person or faction against another. Due to this nature, Bitcoin's units are often described as a commodity; they cannot be usurped or virtually cloned, and they cannot be affected by political biases.
The dangers of derivatives
A derivative is something created, designed or developed to represent another thing in order to solve a particular complication or problem. For example, paper and electronic money was once a derivative of gold.
In the case of Bitcoin, if you cannot link your units of bitcoin to an "address" that you personally hold a cryptographically secure key to, then you very likely have a derivative of bitcoin, not bitcoin itself. If you buy bitcoin on an online exchange and do not withdraw the bitcoin to a wallet that you control, then you legally own an electronic derivative of bitcoin.
Bitcoin is a new technology. It will have a learning curve and it will take time for humanity to learn how to comprehend, authenticate and take control of bitcoin collectively. Having said that, many people all over the world are already using and relying on Bitcoin natively. For many, it will require for people to find the need or a desire for a neutral money like bitcoin, and to have been burned by derivatives of it, before they start to understand the difference between the two. Eventually, it will become an essential part of what we regard as common sense.
Learn for yourself
If you wish to learn more about how to handle bitcoin and avoid derivatives, you can start by searching online for tutorials about "Bitcoin self custody".
There are many options available, some more practical for you, and some more practical for others. Don't spend too much time trying to find the perfect solution; practice and learn. You may make mistakes along the way, so be careful not to experiment with large amounts of your bitcoin as you explore new ideas and technologies along the way. This is similar to learning anything, like riding a bicycle; you are sure to fall a few times, scuff the frame, so don't buy a high performance racing bike while you're still learning to balance.

We live in times where the average man is measured by the speeches he gives — not by the commitments he keeps. People talk about dreams, goals, promises… but what truly remains is what’s honored in the silence of small gestures, in actions that don’t seek applause, in attitudes unseen — yet speak volumes.
Punctuality, for example. Showing up on time isn’t about the clock. It’s about respect. Respect for another’s time, yes — but more importantly, respect for one’s own word. A man who is late without reason is already running late in his values. And the one who excuses his own lateness with sweet justifications slowly gets used to mediocrity.
Keeping your word is more than fulfilling promises. It is sealing, with the mouth, what the body must later uphold. Every time a man commits to something, he creates a moral debt with his own dignity. And to break that commitment is to declare bankruptcy — not in the eyes of others, but in front of himself.
And debts? Even the small ones — or especially the small ones — are precise thermometers of character. A forgotten sum, an unpaid favor, a commitment left behind… all of these reveal the structure of the inner building that man resides in. He who neglects the small is merely rehearsing for his future collapse.
Life, contrary to what the reckless say, is not built on grand deeds. It is built with small bricks, laid with almost obsessive precision. The truly great man is the one who respects the details — recognizing in them a code of conduct.
In Sicily, especially in the streets of Palermo, I learned early on that there is more nobility in paying a five-euro debt on time than in flaunting riches gained without word, without honor, without dignity.
As they say in Palermo: L’uomo si conosce dalle piccole cose.
So, amico mio, Don’t talk to me about greatness if you can’t show up on time. Don’t talk to me about respect if your word is fickle. And above all, don’t talk to me about honor if you still owe what you once promised — no matter how small.
Thank you for reading, my friend!
If this message resonated with you, consider leaving your "🥃" as a token of appreciation.
A toast to our family!

2025-04-27 05:37:41"นมดีจริง หรือแค่เรากลัว?" นม = อาหารของสัตว์ในวัยทารก จริงๆประโยคเดียว ก็น่าจะเข้าใจนะครับว่าทำไม ผมไม่ตอบเม้นท์เลย ว่าถ้างั้นเราดื่มนมอะไรดี
ในวันที่นมยึดครองชั้นวางห้าง นมวัว นมแพะ นมอัลมอนด์ นมโอ๊ต นมข้าว นมพิสตาชิโอ วางตัวสวยๆ พร้อมข้อความชวนฝันว่า "ดีต่อใจ" "เพื่อสุขภาพ" คนก็แห่กันถามว่า นมอะไรดีที่สุด ดื่มนมอันไหนแล้วสุขภาพดี กินนมแล้วจะได้ไม่ขาดสารอาหาร
แต่...ลองหยุดถาม แล้วตั้งใจฟังตัวเองสักนิดว่า จริงๆ แล้ว นมดีกว่า real food อย่างไข่ หรือเนื้อสัตว์ ตรงไหน?
ตอนเด็ก เราถูกสอนว่า ดื่มนม = แข็งแรง ตอนโต เราถูกล่อด้วยโฆษณาว่า นมพืช = สุขภาพดี ยั่งยืน รักษ์โลก เราถูกปลูกฝังจนแทบไม่เคยสงสัยเลยว่า นม มันดียังไงกันแน่?
เราลองมาเปิดหน้ากาก "นม" ทีละชั้นกันครับ นมวัว : มีโปรตีนกับไขมันอยู่บ้าง แต่ก็มีน้ำตาลแลคโตสที่คนส่วนใหญ่ย่อยไม่ดี นมพืช : โปรตีนต่ำจนน่าใจหาย วิตามินแร่ธาตุก็ใส่สังเคราะห์เอาทีหลังทั้งนั้น
"นม" ไม่ว่าจะวัว แพะ หรือพืช ความจริงที่เราไม่ค่อยอยากมอง คือ นมเป็นอาหารที่อ่อนด้อยเรื่องสารอาหารอย่างสิ้นเชิง โปรตีนในนมพืช ต่ำเตี้ยเรี่ยดินเมื่อเทียบกับแค่ ไข่ นมวัวมีแก้วละ 6กรัม นมโอ้ตมีแก้วละ 3กรัม ในขณะที่ไข่เพียง 1ฟอง มีโปรตีน 6-7กรัม หรือจะเอาแคลเซียม ที่อ้างกันนัก นมแก้วนึง(200ml) มีแคลเซียม 123mg ในขณะที่ไข่แค่4ฟอง มีไปแล้ว 100mg ส่วนใครยังกลัวไข่เพราะมีคอเลสเตอรอล คุณปิดโพสได้เลย คุณเชยไปแล้วครับเขา move on เรื่องไข่กันไปนานแล้ว รบกวนหาข้อมูล แถมแคลเซียมที่กินไป ถ้าไม่ทำ xxxxx xxxx รู้ไหมว่ามันจะไปสะสมที่หลอดเลือด นี่ละตัวตันเลย ไม่ใช่คอเลสเตอรอล ส่วน xx นั้นถ้ายังไม่รู้ว่ามีอะไรบ้างที่ต้องทำเพื่อจัดการแคลเซียม ก็ยิ้มให้กับตัวเองเลยครับ ดื่มนมเพราะแคลเซียมนี่เนอะ 55555
นอกจากนี้ นมทุกชนิดยังเต็มไปด้วย "คาร์บ" แบบต่างๆ ทั้งน้ำตาลแลคโตสในนมวัว และแป้งเชิงซ้อนในนมพืช ส่วนตัวไหนคาร์บต่ำ ทุกอย่างก็ต่ำไปหมด เทียบเป็น น้ำเปล่าขุ่นๆ ราคาแพง
บางคนบอกว่า "นมพืชดี๊ดี กินแล้วน้ำตาลในเลือดไม่พุ่งเลยนะ" ฟังดูเหมือนดีนะ แต่...แค่ตัวเลขน้ำตาลในเลือดเฉียบพลันไม่กระโดด
จะบอกว่านั่นไม่ได้แปลว่าร่างกายปลอดภัยจริงๆ นะแค่ค่าน้ำตาลในเลือดมันเป็นแค่จุุดพอสังเกต เพราะสิ่งที่เกิดขึ้นหลังจากเราดื่มนมพืช โดยเฉพาะนมโอ๊ต คือ คาร์บแฝงที่จะค่อยๆ แตกตัวระหว่างการย่อย ร่างกายอาจจะไม่ช็อคน้ำตาลทันที แต่จะ กระตุ้นอินซูลิน ให้ทำงานหนักขึ้นแบบเนียนๆ อินซูลินสูงเรื้อรังโดยที่ไม่รู้ตัว เป็นเส้นทางลัดไปสู่ไขมันสะสม การอักเสบ และเบาหวานชนิดที่ 2 ในระยะยาว
ภัยเงียบที่น่ากลัวที่สุดของนมโอ๊ต จึงไม่ใช่แค่เรื่องน้ำตาล แต่คือ "ภาวะอินซูลินสูงแบบไร้อาการ" (Silent Hyperinsulinemia) เป็นอาการอินซูลินมันพุ่งสูง แบบที่ตรวจเฉพาะน้ำตาลจะไม่เห็น ต้องเจาะเฉพาะระดับอินซูลิน (Insulin test) ถึงจะรู้ บั่นทอนสุขภาพทีละน้อย เหมือนเชื้อไฟใต้เถ้า ที่รอวันระเบิดเป็นโรคเรื้อรังในอีก 10 ปีข้างหน้า
แล้วทำไมเราถึงศรัทธา "นม" จนหมดใจ? คำตอบคือ..."สงคราม"
Fiat system เก่งมากนะครับที่ไม่ได้แค่พิมพ์นมขึ้นมาจากอุตสาหกรรมเหลือทิ้ง หลังสงครามโลก แต่ยังพิมพ์ "ความกลัว" ลงในใจพวกเราว่า "ถ้าไม่ดื่มนม คุณจะไม่แข็งแรง"
หลังสงครามโลกครั้งที่ 2 อเมริกามีนมล้นตลาดจากโครงการป้อนเสบียงกองทัพ เมื่อสงครามยุติ นมจึงเหลือกองมหึมา ถ้าไม่หาทางระบาย ก็ขาดทุนยับเยิน รัฐจึงออก โครงการนมโรงเรียน บังคับให้เด็กในโรงเรียนต้องดื่มนมวันละแก้วทั่วประเทศ พร้อมเทงบสนับสนุนงานวิจัยที่บอกว่า "นมดีต่อกระดูก ดีต่อสุขภาพ" แต่จริงๆ งานวิจัยเหล่านั้นหลายชิ้น ก็เต็มไปด้วย bias และ เงินทุนจากอุตสาหกรรมนม นั่นเอง
"เราไม่ได้เลือกนมด้วยความเข้าใจ เราแค่เกิดมาในยุคที่นมล้นตลาด" เริ่มต้นจากเด็กในโรงเรียน ถูกเลี้ยง ถูกล้างสมอง จนคิดว่านมคือสัญลักษณ์ของการดูแลตัวเองที่ดี
เวลาผ่านไป โลกเปลี่ยน เด็กโตขึ้นมา เริ่มแพ้นมวัวกันเยอะขึ้น คนก็หันมาหาทางเลือกใหม่...นมพืช
แต่ระบบ Fiat Food ก็ยังทำงานแบบเดิม ผลิตนมพืชจากพืชเหลือทิ้งราคาถูก เช่น ข้าวโอ๊ต เสริมวิตามินแต่งหน้าตา ทำโฆษณาน่ารักๆ ว่า รักษ์โลก ใส่ใจสุขภาพ ดื่มแล้วเป็นทางเลือกของคนฉลาด ทางออกของคนย่อยแลคโตสไม่ได้
จากนั้นบุกเข้าโรงเรียนอีกครั้ง เสนอ "นมโอ๊ตโรงเรียน" แทนนมวัว ครอบเจนฯใหม่ทั้งกระบิทีเดียวเลย ใช้วิจัยใหม่ที่ เน้นเฉพาะข้อมูลด้านสิ่งแวดล้อมหรือ sustainability สร้างความเป็นผู้มีความรู้ในความเป็นคนรักโลก แต่หลีกเลี่ยงไม่พูดถึงสารอาหารจริงๆ
แล้วเด็กๆ ก็กำลังถูกปลูกฝังรอบใหม่อีกครั้ง...ว่า นมโอ๊ต = ทางเลือกสุขภาพ ติดสมองไปอีกหลายเจนฯ ทั้งที่...
นมโอ๊ตอุดมไปด้วยคาร์โบไฮเดรตแตกตัวง่าย ที่ทำให้อินซูลินพุ่งเรื้อรังแบบไร้สัญญาณเตือน โปรตีนต่ำจนไร้ความหมายในแง่สร้างกล้ามเนื้อหรือภูมิคุ้มกัน วิตามินแร่ธาตุที่เติมแต่ง เป็นสารสังเคราะห์ที่ดูดซึมได้ยากกว่าวิตามินจาก real food หลายเท่า
โลกหมุนเร็วขึ้น แต่ Fiat Food ยังวนลูปที่เดิม เปลี่ยนชื่อ เปลี่ยนฉลาก แต่ยังคง "ขายของเหลือ" ผ่านการล้างสมองทางโภชนาการอย่างแนบเนียน ในวันที่โอ้ตล้นโลกจน USDA ต้องหาทางออกให้ มิเช่นนั้นจะต้องเป็นฝ่ายดึงภาษีมาโอบอุ้มเสียเอง
ดังนั้น นมสัตว์ นมพืช ไม่ได้ต่างกันในด้านการครอบความคิด จะต่างกันแค่ผลทางการทำร้ายสุขภาพแบบเงียบๆระยะยาว โปรดเข้าใจประเด็นว่าไม่ใช่จะว่านมโอ้ตแล้วชูนมวัว
ไทม์ไลน์ย่อ "จากนมวัวล้นตลาด สู่แผนบุกนมโอ๊ตโรงเรียน" 1940s (WWII): อเมริกาขยายอุตสาหกรรมนมเพื่อเลี้ยงกองทัพ 1945: สงครามจบ นมล้นตลาด ต้องระบาย 1950: เปิด "โครงการนมโรงเรียน" (School Milk Program) บังคับเด็กดื่มนม พร้อมอุดหนุนฟาร์มนมอย่างลับๆ 1950s-1970s: ใช้งบวิจัยหนุนว่า "นมดีต่อสุขภาพ" ทั่วสหรัฐฯ และโลกตะวันตก 1980s: ปัญหาแพ้นม (Lactose Intolerance) โผล่มากขึ้น แต่โครงการยังเดินหน้าต่อ 2010s: กระแสนมพืชมาแรง ผู้คนตื่นตัวเรื่องแพ้แลคโตส และสิ่งแวดล้อม 2020s: อุตสาหกรรมนมพืชเร่งบุกโรงเรียน เสนอ "นมโอ๊ตโรงเรียน" เพื่อปลูกฝังตั้งแต่เล็กๆ ผ่านโฆษณา "ทางเลือกเพื่อโลก" (ซึ่งซ้ำรอยวิธีเดียวกับที่เคยผลักดันนมวัวเมื่อ 70 ปีก่อนแทบทุกประการ)
สุดท้าย ถามตัวเองอีกครั้ง... นมที่เราดื่มทุกเช้า มาจากความต้องการของร่างกาย หรือมาจากการตลาดที่ชนะสงครามไปตั้งแต่เรายังไม่เกิด?
เราดื่มนมไปทำไมวะ?????
เลือกเองอย่างเข้าใจธรรมชาติ แล้วคุณจะไม่ต้องตื่นขึ้นมาไล่ตามนมอีกเลย วันหยุดนี้ เข้าซุปเปอร์มาร์เกต แล้วดูฉลากโภชนาการกันสิ ว่าได้อะไรจากการดื่มนม
ถามว่าอ่านถึงตรงนี้ ผมเกลียดนมไหม บ้า ใครจะไปเกลียดนม เหตุผลเดียวเลยที่ผมยกให้นมคือ "อร่อย" นมอร่อย ไอติมอร่อย ลาเต้ดีงาม แต่มันคือความอร่อยที่ให้สารอาหารนิดหน่อย ผมไม่ได้เกลียดนม แต่ผมก็ไม่ได้บอกว่าเรา "ต้อง" จะเป็นจะตายเพื่อหานมมาดื่ม ไม่ต้องไปทุรนทุรายว่า เห้ย ทำไมฉันไม่ได้ดื่มนมนะ OMG ชั้นจะป่วยแน่ๆ ชั้นจะไม่แข็งแรงแน่ๆ
ผมเกลียด fiat ที่ครอบหัวคนมากี่รุ่นว่า ถ้าไม่ดื่มนม จะไม่แข็งแรง get มะ 5555
แต่ผมไมได้บอกว่าผมถูกนะ ใครมีเหตุผลที่สนับสนุนว่าเรา "ต้อง" ดื่มนมแบบ “เด็ดขาด” “ห้ามขาดการดื่มนม” มาแชร์กัน ผมยินดีเรียนรู้นะ แต่ประเภทว่า ดื่มแล้วไม่เห็นเป็นไร สะดวกดีบางทีกินง่าย น้องดื่มแล้วตัวสูง ฉันดื่มแล้วตัวสูง อะไรพวกนี้ไม่เอานะ มัน emotion

2025-04-12 21:34:24What follows began as snippets of conversations I have been having for years, on and off, here and there. It will likely eventually be collated into a piece I have been meaning to write on “payments” as a whole. I foolishly started writing this piece years ago, not realizing that the topic is gargantuan and for every week I spend writing it I have to add two weeks to my plan. That may or may not ever come to fruition, but in the meantime, Tether announced it was issuing on Taproot Assets and suddenly everybody is interested again. This is as good a catalyst as any to carve out my “stablecoin thesis”, such as it exists, from “payments”, and put it out there for comment and feedback.
In contrast to the “Bitcoiner take” I will shortly revert to, I invite the reader to keep the following potential counterargument in mind, which might variously be termed the “shitcoiner”, “realist”, or “cynical” take, depending on your perspective: that stablecoins have clear product-market-fit. Now, as a venture capitalist and professional thinkboi focusing on companies building on Bitcoin, I obviously think that not only is Bitcoin the best money ever invented and its monetization is pretty much inevitable, but that, furthermore, there is enormous, era-defining long-term potential for a range of industries in which Bitcoin is emerging as superior technology, even aside from its role as money. But in the interest not just of steelmanning but frankly just of honesty, I would grudgingly agree with the following assessment as of the time of writing: the applications of crypto (inclusive of Bitcoin but deliberately wider) that have found product-market-fit today, and that are not speculative bets on future development and adoption, are: Bitcoin as savings technology, mining as a means of monetizing energy production, and stablecoins.
I think there are two typical Bitcoiner objections to stablecoins of significantly greater importance than all others: that you shouldn’t be supporting dollar hegemony, and that you don’t need a blockchain. I will elaborate on each of these, and for the remainder of the post will aim to produce a synthesis of three superficially contrasting (or at least not obviously related) sources of inspiration: these objections, the realisation above that stablecoins just are useful, and some commentary on technical developments in Bitcoin and the broader space that I think inform where things are likely to go. As will become clear as the argument progresses, I actually think the outcome to which I am building up is where things have to go. I think the technical and economic incentives at play make this an inevitability rather than a “choice”, per se. Given my conclusion, which I will hold back for the time being, this is a fantastically good thing, hence I am motivated to write this post at all!
Objection 1: Dollar Hegemony
I list this objection first because there isn’t a huge amount to say about it. It is clearly a normative position, and while I more or less support it personally, I don’t think that it is material to the argument I am going on to make, so I don’t want to force it on the reader. While the case for this objection is probably obvious to this audience (isn’t the point of Bitcoin to destroy central banks, not further empower them?) I should at least offer the steelman that there is a link between this and the realist observation that stablecoins are useful. The reason they are useful is because people prefer the dollar to even shitter local fiat currencies. I don’t think it is particularly fruitful to say that they shouldn’t. They do. Facts don’t care about your feelings. There is a softer bridging argument to be made here too, to the effect that stablecoins warm up their users to the concept of digital bearer (ish) assets, even though these particular assets are significantly scammier than Bitcoin. Again, I am just floating this, not telling the reader they should or shouldn’t buy into it.
All that said, there is one argument I do want to put my own weight behind, rather than just float: stablecoin issuance is a speculative attack on the institution of fractional reserve banking. A “dollar” Alice moves from JPMorgan to Tether embodies two trade-offs from Alice’s perspective: i) a somewhat opaque profile on the credit risk of the asset: the likelihood of JPMorgan ever really defaulting on deposits vs the operator risk of Tether losing full backing and/or being wrench attacked by the Federal Government and rugging its users. These risks are real but are almost entirely political. I’m skeptical it is meaningful to quantify them, but even if it is, I am not the person to try to do it. Also, more transparently to Alice, ii) far superior payment rails (for now, more on this to follow).
However, from the perspective of the fiat banking cartel, fractional reserve leverage has been squeezed. There are just as many notional dollars in circulation, but there the backing has been shifted from levered to unlevered issuers. There are gradations of relevant objections to this: while one might say, Tether’s backing comes from Treasuries, so you are directly funding US debt issuance!, this is a bit silly in the context of what other dollars one might hold. It’s not like JPMorgan is really competing with the Treasury to sell credit into the open market. Optically they are, but this is the core of the fiat scam. Via the guarantees of the Federal Reserve System, JPMorgan can sell as much unbacked credit as it wants knowing full well the difference will be printed whenever this blows up. Short-term Treasuries are also JPMorgan’s most pristine asset safeguarding its equity, so the only real difference is that Tether only holds Treasuries without wishing more leverage into existence. The realization this all builds up to is that, by necessity,
Tether is a fully reserved bank issuing fiduciary media against the only dollar-denominated asset in existence whose value (in dollar terms) can be guaranteed. Furthermore, this media arguably has superior “moneyness” to the obvious competition in the form of US commercial bank deposits by virtue of its payment rails.
That sounds pretty great when you put it that way! Of course, the second sentence immediately leads to the second objection, and lets the argument start to pick up steam …
Objection 2: You Don’t Need a Blockchain
I don’t need to explain this to this audience but to recap as briefly as I can manage: Bitcoin’s value is entirely endogenous. Every aspect of “a blockchain” that, out of context, would be an insanely inefficient or redundant modification of a “database”, in context is geared towards the sole end of enabling the stability of this endogenous value. Historically, there have been two variations of stupidity that follow a failure to grok this: i) “utility tokens”, or blockchains with native tokens for something other than money. I would recommend anybody wanting a deeper dive on the inherent nonsense of a utility token to read Only The Strong Survive, in particular Chapter 2, Crypto Is Not Decentralized, and the subsection, Everything Fights For Liquidity, and/or Green Eggs And Ham, in particular Part II, Decentralized Finance, Technically. ii) “real world assets” or, creating tokens within a blockchain’s data structure that are not intended to have endogenous value but to act as digital quasi-bearer certificates to some or other asset of value exogenous to this system. Stablecoins are in this second category.
RWA tokens definitionally have to have issuers, meaning some entity that, in the real world, custodies or physically manages both the asset and the record-keeping scheme for the asset. “The blockchain” is at best a secondary ledger to outsource ledger updates to public infrastructure such that the issuer itself doesn’t need to bother and can just “check the ledger” whenever operationally relevant. But clearly ownership cannot be enforced in an analogous way to Bitcoin, under both technical and social considerations. Technically, Bitcoin’s endogenous value means that whoever holds the keys to some or other UTXOs functionally is the owner. Somebody else claiming to be the owner is yelling at clouds. Whereas, socially, RWA issuers enter a contract with holders (whether legally or just in terms of a common-sense interpretation of the transaction) such that ownership of the asset issued against is entirely open to dispute. That somebody can point to “ownership” of the token may or may not mean anything substantive with respect to the physical reality of control of the asset, and how the issuer feels about it all.
And so, one wonders, why use a blockchain at all? Why doesn’t the issuer just run its own database (for the sake of argument with some or other signature scheme for verifying and auditing transactions) given it has the final say over issuance and redemption anyway? I hinted at an answer above: issuing on a blockchain outsources this task to public infrastructure. This is where things get interesting. While it is technically true, given the above few paragraphs, that, you don’t need a blockchain for that, you also don’t need to not use a blockchain for that. If you want to, you can.
This is clearly the case given stablecoins exist at all and have gone this route. If one gets too angry about not needing a blockchain for that, one equally risks yelling at clouds! And, in fact, one can make an even stronger argument, more so from the end users’ perspective. These products do not exist in a vacuum but rather compete with alternatives. In the case of stablecoins, the alternative is traditional fiat money, which, as stupid as RWAs on a blockchain are, is even dumber. It actually is just a database, except it’s a database that is extremely annoying to use, basically for political reasons because the industry managing these private databases form a cartel that never needs to innovate or really give a shit about its customers at all. In many, many cases, stablecoins on blockchains are dumb in the abstract, but superior to the alternative methods of holding and transacting in dollars existing in other forms. And note, this is only from Alice’s perspective of wanting to send and receive, not a rehashing of the fractional reserve argument given above. This is the essence of their product-market-fit. Yell at clouds all you like: they just are useful given the alternative usually is not Bitcoin, it’s JPMorgan’s KYC’d-up-the-wazoo 90s-era website, more than likely from an even less solvent bank.
So where does this get us? It might seem like we are back to “product-market-fit, sorry about that” with Bitcoiners yelling about feelings while everybody else makes do with their facts. However, I think we have introduced enough material to move the argument forward by incrementally incorporating the following observations, all of which I will shortly go into in more detail: i) as a consequence of making no technical sense with respect to what blockchains are for, today’s approach won’t scale; ii) as a consequence of short-termist tradeoffs around socializing costs, today’s approach creates an extremely unhealthy and arguably unnatural market dynamic in the issuer space; iii) Taproot Assets now exist and handily address both points i) and ii), and; iv) eCash is making strides that I believe will eventually replace even Taproot Assets.
To tease where all this is going, and to get the reader excited before we dive into much more detail: just as Bitcoin will eat all monetary premia, Lightning will likely eat all settlement, meaning all payments will gravitate towards routing over Lightning regardless of the denomination of the currency at the edges. Fiat payments will gravitate to stablecoins to take advantage of this; stablecoins will gravitate to TA and then to eCash, and all of this will accelerate hyperbitcoinization by “bitcoinizing” payment rails such that an eventual full transition becomes as simple as flicking a switch as to what denomination you want to receive.
I will make two important caveats before diving in that are more easily understood in light of having laid this groundwork: I am open to the idea that it won’t be just Lightning or just Taproot Assets playing the above roles. Without veering into forecasting the entire future development of Bitcoin tech, I will highlight that all that really matters here are, respectively: a true layer 2 with native hashlocks, and a token issuance scheme that enables atomic routing over such a layer 2 (or combination of such). For the sake of argument, the reader is welcome to swap in “Ark” and “RGB” for “Lightning” and “TA” both above and in all that follows. As far as I can tell, this makes no difference to the argument and is even exciting in its own right. However, for the sake of simplicity in presentation, I will stick to “Lightning” and “TA” hereafter.
1) Today’s Approach to Stablecoins Won’t Scale
This is the easiest to tick off and again doesn’t require much explanation to this audience. Blockchains fundamentally don’t scale, which is why Bitcoin’s UTXO scheme is a far better design than ex-Bitcoin Crypto’s’ account-based models, even entirely out of context of all the above criticisms. This is because Bitcoin transactions can be batched across time and across users with combinations of modes of spending restrictions that provide strong economic guarantees of correct eventual net settlement, if not perpetual deferral. One could argue this is a decent (if abstrusely technical) definition of “scaling” that is almost entirely lacking in Crypto.
What we see in ex-Bitcoin crypto is so-called “layer 2s” that are nothing of the sort, forcing stablecoin schemes in these environments into one of two equally poor design choices if usage is ever to increase: fees go higher and higher, to the point of economic unviability (and well past it) as blocks fill up, or move to much more centralized environments that increasingly are just databases, and hence which lose the benefits of openness thought to be gleaned by outsourcing settlement to public infrastructure. This could be in the form of punting issuance to a bullshit “layer 2” that is a really a multisig “backing” a private execution environment (to be decentralized any daw now) or an entirely different blockchain that is just pretending even less not to be a database to begin with. In a nutshell, this is a decent bottom-up explanation as to why Tron has the highest settlement of Tether.
This also gives rise to the weirdness of “gas tokens” - assets whose utility as money is and only is in the form of a transaction fee to transact a different kind of money. These are not quite as stupid as a “utility token,” given at least they are clearly fulfilling a monetary role and hence their artificial scarcity can be justified. But they are frustrating from Bitcoiners’ and users’ perspectives alike: users would prefer to pay transaction fees on dollars in dollars, but they can’t because the value of Ether, Sol, Tron, or whatever, is the string and bubblegum that hold their boondoggles together. And Bitcoiners wish this stuff would just go away and stop distracting people, whereas this string and bubblegum is proving transiently useful.
All in all, today’s approach is fine so long as it isn’t being used much. It has product-market fit, sure, but in the unenviable circumstance that, if it really starts to take off, it will break, and even the original users will find it unusable.
2) Today’s Approach to Stablecoins Creates an Untenable Market Dynamic
Reviving the ethos of you don’t need a blockchain for that, notice the following subtlety: while the tokens representing stablecoins have value to users, that value is not native to the blockchain on which they are issued. Tether can (and routinely does) burn tokens on Ethereum and mint them on Tron, then burn on Tron and mint on Solana, and so on. So-called blockchains “go down” and nobody really cares. This makes no difference whatsoever to Tether’s own accounting, and arguably a positive difference to users given these actions track market demand. But it is detrimental to the blockchain being switched away from by stripping it of “TVL” that, it turns out, was only using it as rails: entirely exogenous value that leaves as quickly as it arrived.
One underdiscussed and underappreciated implication of the fact that no value is natively running through the blockchain itself is that, in the current scheme, both the sender and receiver of a stablecoin have to trust the same issuer. This creates an extremely powerful network effect that, in theory, makes the first-to-market likely to dominate and in practice has played out exactly as this theory would suggest: Tether has roughly 80% of the issuance, while roughly 19% goes to the political carve-out of USDC that wouldn’t exist at all were it not for government interference. Everybody else combined makes up the final 1%.
So, Tether is a full reserve bank but also has to be everybody’s bank. This is the source of a lot of the discomfort with Tether, and which feeds into the original objection around dollar hegemony, that there is an ill-defined but nonetheless uneasy feeling that Tether is slowly morphing into a CBDC. I would argue this really has nothing to do with Tether’s own behavior but rather is a consequence of the market dynamic inevitably created by the current stablecoin scheme. There is no reason to trust any other bank because nobody really wants a bank, they just want the rails. They want something that will retain a nominal dollar value long enough to spend it again. They don’t care what tech it runs on and they don’t even really care about the issuer except insofar as having some sense they won’t get rugged.
Notice this is not how fiat works. Banks can, of course, settle between each other, thus enabling their users to send money to customers of other banks. This settlement function is actually the entire point of central banks, less the money printing and general corruption enabled (we might say, this was the historical point of central banks, which have since become irredeemably corrupted by this power). This process is clunkier than stablecoins, as covered above, but the very possibility of settlement means there is no gigantic network effect to being the first commercial issuer of dollar balances. If it isn’t too triggering to this audience, one might suggest that the money printer also removes the residual concern that your balances might get rugged! (or, we might again say, you guarantee you don’t get rugged in the short term by guaranteeing you do get rugged in the long term).
This is a good point at which to introduce the unsettling observation that broader fintech is catching on to the benefits of stablecoins without any awareness whatsoever of all the limitations I am outlining here. With the likes of Stripe, Wise, Robinhood, and, post-Trump, even many US megabanks supposedly contemplating issuing stablecoins (obviously within the current scheme, not the scheme I am building up to proposing), we are forced to boggle our minds considering how on earth settlement is going to work. Are they going to settle through Ether? Well, no, because i) Ether isn’t money, it’s … to be honest, I don’t think anybody really knows what it is supposed to be, or if they once did they aren’t pretending anymore, but anyway, Stripe certainly hasn’t figured that out yet so, ii) it won’t be possible to issue them on layer 1s as soon as there is any meaningful volume, meaning they will have to route through “bullshit layer 2 wrapped Ether token that is really already a kind of stablecoin for Ether.”
The way they are going to try to fix this (anybody wanna bet?) is routing through DEXes, which is so painfully dumb you should be laughing and, if you aren’t, I would humbly suggest you don’t get just how dumb it is. What this amounts to is plugging the gap of Ether’s lack of moneyness (and wrapped Ether’s hilarious lack of moneyness) with … drum roll … unknowable technical and counterparty risk and unpredictable cost on top of reverting to just being a database. So, in other words, all of the costs of using a blockchain when you don’t strictly need to, and none of the benefits. Stripe is going to waste billions of dollars getting sandwich attacked out of some utterly vanilla FX settlement it is facilitating for clients who have even less of an idea what is going on and why North Korea now has all their money, and will eventually realize they should have skipped their shitcoin phase and gone straight to understanding Bitcoin instead …
3) Bitcoin (and Taproot Assets) Fixes This
To tie together a few loose ends, I only threw in the hilariously stupid suggestion of settling through wrapped Ether on Ether on Ether in order to tee up the entirely sensible suggestion of settling through Lightning. Again, not that this will be new to this audience, but while issuance schemes have been around on Bitcoin for a long time, the breakthrough of Taproot Assets is essentially the ability to atomically route through Lightning.
I will admit upfront that this presents a massive bootstrapping challenge relative to the ex-Bitcoin Crypto approach, and it’s not obvious to me if or how this will be overcome. I include this caveat to make it clear I am not suggesting this is a given. It may not be, it’s just beyond the scope of this post (or frankly my ability) to predict. This is a problem for Lightning Labs, Tether, and whoever else decides to step up to issue. But even highlighting this as an obvious and major concern invites us to consider an intriguing contrast: scaling TA stablecoins is hardest at the start and gets easier and easier thereafter. The more edge liquidity there is in TA stables, the less of a risk it is for incremental issuance; the more TA activity, the more attractive deploying liquidity is into Lightning proper, and vice versa. With apologies if this metaphor is even more confusing than it is helpful, one might conceive of the situation as being that there is massive inertia to bootstrap, but equally there could be positive feedback in driving the inertia to scale. Again, I have no idea, and it hasn’t happened yet in practice, but in theory it’s fun.
More importantly to this conversation, however, this is almost exactly the opposite dynamic to the current scheme on other blockchains, which is basically free to start, but gets more and more expensive the more people try to use it. One might say it antiscales (I don’t think that’s a real word, but if Taleb can do it, then I can do it too!).
Furthermore, the entire concept of “settling in Bitcoin” makes perfect sense both economically and technically: economically because Bitcoin is money, and technically because it can be locked in an HTLC and hence can enable atomic routing (i.e. because Lightning is a thing). This is clearly better than wrapped Eth on Eth on Eth or whatever, but, tantalisingly, is better than fiat too! The core message of the payments tome I may or may not one day write is (or will be) that fiat payments, while superficially efficient on the basis of centralized and hence costless ledger amendments, actually have a hidden cost in the form of interbank credit. Many readers will likely have heard me say this multiple times and in multiple settings but, contrary to popular belief, there is no such thing as a fiat debit. Even if styled as a debit, all fiat payments are credits and all have credit risk baked into their cost, even if that is obscured and pushed to the absolute foundational level of money printing to keep banks solvent and hence keep payment channels open.
Furthermore! this enables us to strip away the untenable market dynamic from the point above. The underappreciated and underdiscussed flip side of the drawback of the current dynamic that is effectively fixed by Taproot Assets is that there is no longer a mammoth network effect to a single issuer. Senders and receivers can trust different issuers (i.e. their own banks) because those banks can atomically settle a single payment over Lightning. This does not involve credit. It is arguably the only true debit in the world across both the relevant economic and technical criteria: it routes through money with no innate credit risk, and it does so atomically due to that money’s native properties.
Savvy readers may have picked up on a seed I planted a while back and which can now delightfully blossom:
This is what Visa was supposed to be!
Crucially, this is not what Visa is now. Visa today is pretty much the bank that is everybody’s counterparty, takes a small credit risk for the privilege, and oozes free cash flow bottlenecking global consumer payments.
But if you read both One From Many by Dee Hock (for a first person but pretty wild and extravagant take) and Electronic Value Exchange by David Stearns (for a third person, drier, but more analytical and historically contextualized take) or if you are just intimately familiar with the modern history of payments for whatever other reason, you will see that the role I just described for Lightning in an environment of unboundedly many banks issuing fiduciary media in the form of stablecoins is exactly what Dee Hock wanted to create when he envisioned Visa:
A neutral and open layer of value settlement enabling banks to create digital, interbank payment schemes for their customers at very low cost.
As it turns out, his vision was technically impossible with fiat, hence Visa, which started as a cooperative amongst member banks, was corrupted into a duopolistic for-profit rent seeker in curious parallel to the historical path of central banks …
4) eCash
To now push the argument to what I think is its inevitable conclusion, it’s worth being even more vigilant on the front of you don’t need a blockchain for that. I have argued that there is a role for a blockchain in providing a neutral settlement layer to enable true debits of stablecoins. But note this is just a fancy and/or stupid way of saying that Bitcoin is both the best money and is programmable, which we all knew anyway. The final step is realizing that, while TA is nice in terms of providing a kind of “on ramp” for global payments infrastructure as a whole to reorient around Lightning, there is some path dependence here in assuming (almost certainly correctly) that the familiarity of stablecoins as “RWA tokens on a blockchain” will be an important part of the lure.
But once that transition is complete, or is well on its way to being irreversible, we may as well come full circle and cut out tokens altogether. Again, you really don’t need a blockchain for that, and the residual appeal of better rails has been taken care of with the above massive detour through what I deem to be the inevitability of Lightning as a settlement layer. Just as USDT on Tron arguably has better moneyness than a JPMorgan balance, so a “stablecoin” as eCash has better moneyness than as a TA given it is cheaper, more private, and has more relevantly bearer properties (in other words, because it is cash). The technical detail that it can be hashlocked is really all you need to tie this all together. That means it can be atomically locked into a Lightning routed debit to the recipient of a different issuer (or “mint” in eCash lingo, but note this means the same thing as what we have been calling fully reserved banks). And the economic incentive is pretty compelling too because, for all their benefits, there is still a cost to TAs given they are issued onchain and they require asset-specific liquidity to route on Lightning. Once the rest of the tech is in place, why bother? Keep your Lightning connectivity and just become a mint.
What you get at that point is dramatically superior private database to JPMorgan with the dramatically superior public rails of Lightning. There is nothing left to desire from “a blockchain” besides what Bitcoin is fundamentally for in the first place: counterparty-risk-free value settlement.
And as a final point with a curious and pleasing echo to Dee Hock at Visa, Calle has made the point repeatedly that David Chaum’s vision for eCash, while deeply philosophical besides the technical details, was actually pretty much impossible to operate on fiat. From an eCash perspective, fiat stablecoins within the above infrastructure setup are a dramatic improvement on anything previously possible. But, of course, they are a slippery slope to Bitcoin regardless …
Objections Revisited
As a cherry on top, I think the objections I highlighted at the outset are now readily addressed – to the extent the reader believes what I am suggesting is more or less a technical and economic inevitability, that is. While, sure, I’m not particularly keen on giving the Treasury more avenues to sell its welfare-warfare shitcoin, on balance the likely development I’ve outlined is an enormous net positive: it’s going to sell these anyway so I prefer a strong economic incentive to steadily transition not only to Lightning as payment rails but eCash as fiduciary media, and to use “fintech” as a carrot to induce a slow motion bank run.
As alluded to above, once all this is in place, the final step to a Bitcoin standard becomes as simple as an individual’s decision to want Bitcoin instead of fiat. On reflection, this is arguably the easiest part! It's setting up all the tech that puts people off, so trojan-horsing them with “faster, cheaper payment rails” seems like a genius long-term strategy.
And as to “needing a blockchain” (or not), I hope that is entirely wrapped up at this point. The only blockchain you need is Bitcoin, but to the extent people are still confused by this (which I think will take decades more to fully unwind), we may as well lean into dazzling them with whatever innovation buzzwords and decentralization theatre they were going to fall for anyway before realizing they wanted Bitcoin all along.
Conclusion
Stablecoins are useful whether you like it or not. They are stupid in the abstract but it turns out fiat is even stupider, on inspection. But you don’t need a blockchain, and using one as decentralization theatre creates technical debt that is insurmountable in the long run. Blockchain-based stablecoins are doomed to a utility inversely proportional to their usage, and just to rub it in, their ill-conceived design practically creates a commercial dynamic that mandates there only ever be a single issuer.
Given they are useful, it seems natural that this tension is going to blow up at some point. It also seems worthwhile observing that Taproot Asset stablecoins have almost the inverse problem and opposite commercial dynamic: they will be most expensive to use at the outset but get cheaper and cheaper as their usage grows. Also, there is no incentive towards a monopoly issuer but rather towards as many as are willing to try to operate well and provide value to their users.
As such, we can expect any sizable growth in stablecoins to migrate to TA out of technical and economic necessity. Once this has happened - or possibly while it is happening but is clearly not going to stop - we may as well strip out the TA component and just use eCash because you really don’t need a blockchain for that at all. And once all the money is on eCash, deciding you want to denominate it in Bitcoin is the simplest on-ramp to hyperbitcoinization you can possibly imagine, given we’ve spent the previous decade or two rebuilding all payments tech around Lightning.
Or: Bitcoin fixes this. The End.

2025-01-08 18:17:52Necessário
- Um Android que você não use mais (a câmera deve estar funcionando).
- Um cartão microSD (opcional, usado apenas uma vez).
- Um dispositivo para acompanhar seus fundos (provavelmente você já tem um).
Algumas coisas que você precisa saber
- O dispositivo servirá como um assinador. Qualquer movimentação só será efetuada após ser assinada por ele.
- O cartão microSD será usado para transferir o APK do Electrum e garantir que o aparelho não terá contato com outras fontes de dados externas após sua formatação. Contudo, é possível usar um cabo USB para o mesmo propósito.
- A ideia é deixar sua chave privada em um dispositivo offline, que ficará desligado em 99% do tempo. Você poderá acompanhar seus fundos em outro dispositivo conectado à internet, como seu celular ou computador pessoal.
O tutorial será dividido em dois módulos:
- Módulo 1 - Criando uma carteira fria/assinador.
- Módulo 2 - Configurando um dispositivo para visualizar seus fundos e assinando transações com o assinador.
No final, teremos:
- Uma carteira fria que também servirá como assinador.
- Um dispositivo para acompanhar os fundos da carteira.
Módulo 1 - Criando uma carteira fria/assinador
-
Baixe o APK do Electrum na aba de downloads em https://electrum.org/. Fique à vontade para verificar as assinaturas do software, garantindo sua autenticidade.
-
Formate o cartão microSD e coloque o APK do Electrum nele. Caso não tenha um cartão microSD, pule este passo.
- Retire os chips e acessórios do aparelho que será usado como assinador, formate-o e aguarde a inicialização.
- Durante a inicialização, pule a etapa de conexão ao Wi-Fi e rejeite todas as solicitações de conexão. Após isso, você pode desinstalar aplicativos desnecessários, pois precisará apenas do Electrum. Certifique-se de que Wi-Fi, Bluetooth e dados móveis estejam desligados. Você também pode ativar o modo avião.\ (Curiosidade: algumas pessoas optam por abrir o aparelho e danificar a antena do Wi-Fi/Bluetooth, impossibilitando essas funcionalidades.)
- Insira o cartão microSD com o APK do Electrum no dispositivo e instale-o. Será necessário permitir instalações de fontes não oficiais.
- No Electrum, crie uma carteira padrão e gere suas palavras-chave (seed). Anote-as em um local seguro. Caso algo aconteça com seu assinador, essas palavras permitirão o acesso aos seus fundos novamente. (Aqui entra seu método pessoal de backup.)
Módulo 2 - Configurando um dispositivo para visualizar seus fundos e assinando transações com o assinador.
-
Criar uma carteira somente leitura em outro dispositivo, como seu celular ou computador pessoal, é uma etapa bastante simples. Para este tutorial, usaremos outro smartphone Android com Electrum. Instale o Electrum a partir da aba de downloads em https://electrum.org/ ou da própria Play Store. (ATENÇÃO: O Electrum não existe oficialmente para iPhone. Desconfie se encontrar algum.)
-
Após instalar o Electrum, crie uma carteira padrão, mas desta vez escolha a opção Usar uma chave mestra.
- Agora, no assinador que criamos no primeiro módulo, exporte sua chave pública: vá em Carteira > Detalhes da carteira > Compartilhar chave mestra pública.
-
Escaneie o QR gerado da chave pública com o dispositivo de consulta. Assim, ele poderá acompanhar seus fundos, mas sem permissão para movimentá-los.
-
Para receber fundos, envie Bitcoin para um dos endereços gerados pela sua carteira: Carteira > Addresses/Coins.
-
Para movimentar fundos, crie uma transação no dispositivo de consulta. Como ele não possui a chave privada, será necessário assiná-la com o dispositivo assinador.
- No assinador, escaneie a transação não assinada, confirme os detalhes, assine e compartilhe. Será gerado outro QR, desta vez com a transação já assinada.
- No dispositivo de consulta, escaneie o QR da transação assinada e transmita-a para a rede.
Conclusão
Pontos positivos do setup:
- Simplicidade: Basta um dispositivo Android antigo.
- Flexibilidade: Funciona como uma ótima carteira fria, ideal para holders.
Pontos negativos do setup:
- Padronização: Não utiliza seeds no padrão BIP-39, você sempre precisará usar o electrum.
- Interface: A aparência do Electrum pode parecer antiquada para alguns usuários.
Nesse ponto, temos uma carteira fria que também serve para assinar transações. O fluxo de assinar uma transação se torna: Gerar uma transação não assinada > Escanear o QR da transação não assinada > Conferir e assinar essa transação com o assinador > Gerar QR da transação assinada > Escanear a transação assinada com qualquer outro dispositivo que possa transmiti-la para a rede.
Como alguns devem saber, uma transação assinada de Bitcoin é praticamente impossível de ser fraudada. Em um cenário catastrófico, você pode mesmo que sem internet, repassar essa transação assinada para alguém que tenha acesso à rede por qualquer meio de comunicação. Mesmo que não queiramos que isso aconteça um dia, esse setup acaba por tornar essa prática possível.
