At this rate you're risking breaking people's trust until someone makes you obsolete.

🚨 We are receiving reports of hot wallets on BTCPay Servers being swept by unauthorized attackers.
If you're running an instance, please shut it down (./btcpay-down.sh) until we complete the investigation.

Así cierra @labitconf 2026
Felices 18 años desde el white paper que marcó un antes y un después en cómo entendemos el dinero, la confianza y el poder del open source.
Gracias a quienes pasaron a saludar, preguntaron o se inscribieron a un curso.
Nos vemos en el aula 💜

On this day in 2008, Satoshi Nakamoto introduced the world to bitcoin through the publication of the bitcoin whitepaper.
What began as a proposal for a peer-to-peer electronic cash system has grown into a global ecosystem, bringing together people from different backgrounds to build, learn, create, and explore what's possible with bitcoin.
At Btrust, we're working to ensure that more developers across the Global Majority have the skills, resources, and opportunities to be part of that journey. The work continues, one contributor at a time.
Happy bitcoin whitepaper day! 🧡

Two months ago, alongside @Coinbase and @danboneh, we co-hosted a post-quantum workshop for cryptographers, protocol engineers, hardware wallet manufacturers, and institutional voices working on Bitcoin’s preparedness for a CRQC.
Today, we’re sharing transcripts from the event and a blog post summarizing the discussions: lclhost.org/blog/quantum-wor…
A special thank you to our speakers and session leaders: @danboneh, @asanso, @LindellYehuda, Pieter Wuille, @conduition_io, @n1ckler, @P3b7_, and Justin of Localhost, everyone who traveled to attend, and the @MARAFoundation_ for sponsoring our post-event dinner.
We hope this workshop leads to more in-person opportunities to study Bitcoin’s Post-Quantum Problem (PQP).
Finally, thank you to @btctranscripts for hosting the transcripts of every talk and session: btctranscripts.com/quantum-w…

🧡 ¡Nueva etapa para el talento que construye Bitcoin!
Librería de Satoshi ahora es @ismosxyz ⚡ Desde 2021 formando a quienes construyen el protocolo de Bitcoin en español, y ahora también en más idiomas.
Porque el talento está en todas partes, y acercar oportunidades también es construir un ecosistema más fuerte. 🟠
¡Felicitaciones a todo el equipo por este nuevo paso! Nos vemos en @labitconf 🚀
Librería de Satoshi is now ISMOS 🎉
Five years teaching Technical Bitcoin in Spanish taught us this: language shouldn’t decide who gets to learn, and building Bitcoin well starts with its foundations.
A new name for a bigger mission.
Cryptography, math, software engineering, AI and critical thinking, in more languages and more countries, all built on the foundations Bitcoin taught us.

🚨 BREAKING: Three new Bitcoin Core vulnerabilities discovered including a bug allowing attackers to remotely brick nodes.
The vulnerabilities include two medium-severity flaws that could allow malicious peers to exhaust node memory and a third that could corrupt blockchain undo data under extreme conditions. @ProjectLoupe, an AI-powered security initiative at @spiral_xyz, independently identified the vulnerabilities alongside other researchers, including @L0RINC of the #Bitcoin Red Team 🟥.
Fixes have been released in Bitcoin Core versions 29.5, 30.4, 31.2, and 32.1, although certain 32-bit and FAT32 configurations remain vulnerable to the third issue.
