📮 钱包助记词能不能用中文显示?比特币开发者正在讨论 现在 BIP39 助记词只有英文。全世界的非英语用户备份钱包时,只能对着一串英文单词,容易拼错、看不懂、心里没底。 比特币开发邮件列表 bitcoindev 上,有人(开发者 Daniel)提了个办法,项目叫 TZUR:让钱包用本地语言显示和输入助记词,但底层加密一个字都不改。真正"算数"的还是那套标准英文词表,生成密钥前,先在内部把本地语言换回英文,再做后面所有运算。说白了就是加一层"翻译皮肤"——不是新方案,也不取代 BIP39。 讨论里最有价值的是一个安全隐患。开发者 conduition 指出:同样一串法语词,可能是"老式法语 BIP39",也可能是这套"TZUR 法语显示版",两套规则会算出完全不同的钱包。软件要是猜错,用户恢复时打开的是个空钱包,真正的币在另一边——这种歧义是会丢币的。 Daniel 接受了这个担忧,给出三条规则:一、绝不让软件自动猜模式;二、用元数据(语言代码、版本号、词表文件的 SHA256 指纹)明确标记到底是哪套词表;三、永远保留英文助记词作为通用恢复形式。也就是把 TZUR 死死限定在"显示层",不碰密钥怎么生成。 目前结论:方向上没人反对,但讨论还很早期,只有一个人回应,钱包厂商和核心开发者都还没表态,离正式提案还远。 —— 🔮 下期:抗量子签名(quantum-resistant signatures,应对未来量子计算机威胁的方案)。这是近期 bitcoindev 讨论最集中的方向,有多个提案在交锋,下期梳理一下。

BIP-361: Let's assume a fork happens. My coin will be the one in which coins that will never be used again anyways will be frozen. Yours will be the pure ideological coin. For what happens to my coin: Look at the ETH price after July 2016. 1/2 #Bitcoin #BTC #BitcoinDev #Crypto

𝐂𝐨𝐧𝐜𝐞𝐩𝐭 𝐨𝐟 𝐭𝐡𝐞 𝐃𝐚𝐲: 𝐖𝐨𝐫𝐦𝐡𝐨𝐥𝐞 𝐀𝐭𝐭𝐚𝐜𝐤 In distributed networks, assumptions about topology matter. A wormhole attack occurs when an adversary tunnels packets between two distant parts of the network, making nodes appear closer than they actually are. The result is distorted routing and manipulated message propagation. Studying these attack models sharpens our thinking about network resilience. Security starts with understanding the adversary. ⚡ #Bitcoin #DadaDevs #BitcoinDev #BitcoinDevelopment

Day 4 closed with purpose depth. B4OS is Librería de Satoshi’s training program for senior developers. Judy Imasuen @jnpunch (@HRF) reminded us why contributors matter: in many places, Bitcoin isn’t an “investment”—it’s access when traditional rails fail. Then Fernando @LedesmaNando took us into Taproot: privacy and scalability as architecture—better ways to express spending conditions, reduce on-chain footprint, and keep verification sane. If we care about freedom, we build for it. Financial freedom matters. Bitcoin is sovereignty 🇪🇨 El Día 4 cerró con propósito profundidad. B4OS es el programa de formación para developers senior de Librería de Satoshi. Judy Imasuen (HRF) nos recordó por qué importan los contributors open source: en muchos lugares, Bitcoin no es “inversión”, es acceso cuando lo tradicional está bloqueado. Después, Fernando nos metió en Taproot: privacidad y escalabilidad como arquitectura: mejores formas de expresar condiciones de gasto, reducir huella on-chain y mantener la verificación razonable. Si nos importa la libertad, construimos para ella. La libertad financiera importa. Bitcoin es soberanía. #B4OS #Bitcoin #Taproot #BitcoinDev #FOSS

Week 2 — Day 4 (recap). Fox @FedeZupicich brought clarity on building a Bitcoin career: plan your path, do the work, and approach grants with intention—not hope. Then we went hands-on with @Bilthon : a regtest escrow/lending setup—locking BTC as collateral, issuing fiat credit without selling, and learning where risk actually lives (LTV, liquidation, shared control). Librería de Satoshi is making Bitcoin technical education accessible. ES Semana 2 — Día 4 (recap). Fox desarrolló el mapa para construir una carrera en Bitcoin: planificar el camino, ejecutar y aplicar a grants con intención, no la suerte. Después, práctica con Bilthon: setup en regtest de escrow/lending creando una multisig. Desde bloquear BTC como colateral, obtener crédito en fiat sin vender, y entender dónde vive el riesgo (LTV, liquidación y control compartido). Librería de Satoshi está haciendo accesible la educación técnica de Bitcoin. #B4OS #BitcoinDev #FOSS #OpenSource

Just published a short explainer on the UTXO model — the foundation of Bitcoin. This video is part of the Mastering Taproot series, a developer-focused course on understanding Bitcoin through programming. Also my first attempt producing a technical explainer using AI tools (voice, subtitles, whiteboard visuals). Still experimenting with the workflow — hope it helps more developers understand Bitcoin.

Happening now: GOSTR — Git and Other Stuff: Tricks and Recommendations with @JGMontoyaS & Josefina from @whitenoisechat (B4OS Alumni). This isn’t “Git basics.” It’s the real workflow: how to keep your history clean, reduce review friction, and move faster without breaking trust — plus the “other stuff” they’ve learned building in the ecosystem (including Nostr). Alumni teaching what actually works. That’s how the culture compounds. Librería de Satoshi is making Bitcoin technical education accessible. 🇨🇱 Ahora mismo: GOSTR, "Git and Other Stuff: Tricks and Recommendations" con Javier y Josefina de Whitenoise (B4OS Alumni). No es “Git básico”. Es workflow real: cómo mantener el historial limpio, reducir fricción en el review y avanzar más rápido sin romper confianza, más el “other stuff” que aprendieron construyendo en el ecosistema (incluyendo IA y Nostr). Alumni enseñando lo que de verdad funciona. Así compone la cultura. Librería de Satoshi está haciendo accesible la educación técnica de Bitcoin. #B4OS #BitcoinDev #FOSS #OpenSource #Git

Now with @jarolrod: PR Review, with a philosophy layer. Same diff, sharper lens: state your intent, keep scope tight, make claims testable, and write so a reviewer can verify—not guess. In Bitcoin open source, review isn’t bureaucracy. It’s the quality system. Librería de Satoshi is making Bitcoin technical education accessible. 🇨🇴 Ahora con @jarolrod: PR Review, pero con una capa de filosofía. Mismo diff, otra lupa: dejar clara la intención, acotar el alcance, hacer afirmaciones testeables y escribir para que un reviewer pueda verificar—no adivinar. En el open source de Bitcoin, el review no es burocracia. Es el sistema de calidad. Librería de Satoshi está haciendo accesible la educación técnica de Bitcoin. #B4OS #PullRequests #BitcoinDev #FOSS

B4OS — Librería de Satoshi’s training program for senior developers — hits Day 3 in Week 2. Back in the classroom. Daniela Brozzoni @danielabrozzoni  ran a hands-on session on Bitcoin Core code review. Not just reading diffs—learning to think like a reviewer: spot assumptions, stress-test edge cases, and understand what “reviewable” actually means. We closed with a real PR review exercise. Review isn’t a formality—it’s how open source moves. 🇺🇾 B4OS, el programa de formación de Librería de Satoshi para developers senior, llega al Día 3 de la segunda semana. De vuelta en el aula. Daniela Brozzoni lideró una sesión práctica de code review en Bitcoin Core. No se trata solo de leer diffs: es aprender a pensar como reviewer; detectar supuestos, poner a prueba casos borde y entender qué significa realmente “ser revisable”. Cerramos con un ejercicio real de revisión de PR. El review no es una formalidad: es cómo avanza el open source. #B4OS #BitcoinDev #FOSS #OpenSource #PullRequests

Happening now: @oz_21m on What makes a good pull request — starting from the principles. Oscar opened the talk about Fedi (@fedibtc) and the Fedimint model: real users, real constraints, real stakes. Then we moved to crafting PRs. It's not “how to submit it.” It's how to make reviewable: a clear intent, tight scope, reproducible context, and respect for the reviewer’s time. 🇵🇪 (ES) Ahora mismo: @oz_21m sobre cómo se hace un buen pull request,  arrancando desde los fundamentos. Óscar comenzó su presentación sobre Fedi (@fedibtc) y el modelo de Fedimint: usuarios reales, restricciones reales, riesgos reales. Continuamos con el arte de crear PRs. No se trata de “cómo enviarlo”. Se trata de cómo hacerlo revisable: una intención clara, alcance acotado, contexto reproducible y respeto por el tiempo de quien revisa. #B4OS #BitcoinDev #PullRequests #FOSS

Day 2 of Week 2 at B4OS Residency. Short walk, breakfast, commute — then back with @0xB10C Same mission: sharpen our tooling, reduce guesswork, and make progress you can verify. 🇪🇸 Día 2 de la semana 2 en la Residencia B4OS. Caminata corta, desayuno, traslado — y volvemos con 0xB10C  Misma misión: mejores herramientas, menos suposiciones y progreso verificable. #B4OS #BitcoinDev #FOSS

Today’s rhythm at the Residency: review culture. We started with stand-up, then @sliv3r__ and Nymius put devs on the spot: bring your commits, defend your PR, absorb feedback, and improve the contribution — two B4OS alumni leading by example and strengthening the next generation of contributors. Later, we shifted from mechanics to mindset with Bitcoin Unfiltered, with mentors like @0xB10C, @jarolrod, @danielabrozzoni, @oz_21m, and Matthew Zipkin from @ChaincodeLabs reflecting on what it actually takes to become (and remain) useful in FOSS. Same theme, two angles: process principles. 🇲🇽 El ritmo de hoy en la Residencia: cultura de review. Arrancamos con stand-up y después @sliv3r__ y Nymius pusieron a los devs a prueba: traer commits, defender el PR, recibir feedback y mejorar la contribución; dos alumni de B4OS liderando con el ejemplo y fortaleciendo a la próxima generación de contributors. Más tarde pasamos de la mecánica a la mentalidad con Bitcoin Unfiltered, con mentores como @0xB10C, @jarolrod, @danielabrozzoni, @oz_21m y Matthew Zipkin de @ChaincodeLabs reflexionando sobre lo que realmente implica volverse (y mantenerse) útil en FOSS.
