Brink grantee @conduition_io presented on the state of post-quantum Bitcoin research: - Post-quantum output types - Quantum canaries and tripwires - Freezing, ignoring, or rate-limiting Satoshi-era coins - Rescue protocols - Hash-based, lattice, isogeny signature schemes - Q&A

Yesterday, Localhost team member @pseudoramdom joined the Optech recap podcast to discuss the staletip network message. Tune in if you're interested in some of the lower level mechanics of this recently proposed idea!

One more thing: the new QML based Bitcoin Core GUI is available for adventurous testers only as an early preview demo. We've had some rounds of testing with a select group of devs and the great team over at @lclhostresearch giving good feedback and finding bugs. It’s experimental, signet-only, and not an official Bitcoin Core release. Try it and tell us (@johnny9dev, @pseudoramdom) what works and what you don't like: None of this would be possible without the @bitcoin_design community and their benevolent dictator @GBKS Goal is to get this across the finish line for the following Bitcoin Core release. 🌎🌍🌏

@lclhostresearch Thanks for sponsoring this @lclhostresearch! peer-observer being a honey-pot means giving wide access to the "production" instance risks leaking node IPs. The demo instance has been very useful for new contributors to explore and test.

Have you seen @0xB10C's instance? This is another tool that we financially support! peer-observer is useful for detecting attacks and other anomalies in the Bitcoin P2P network. The demo instance let's curious individuals explore and experiment with the infrastructure. For us, the project has been particularly useful. b10c attached a FIBRE node to peer-observer and discovered two issues. Thank you @0xB10C!

We are honored to sponsor and two useful pieces of infrastructure. @FarsideInsights, thank you for including us in the future of these two projects. Wishing the former BitMex team a soft landing and a graceful transition into the next chapter of their journey.

Today, Bitcoin Policy Institute and a broad coalition from across the digital-asset ecosystem are publishing an open letter calling on the world’s leading AI labs to provide qualified open-source defenders with trusted access to frontier AI models. The past several weeks have made the need for this abundantly clear. The people defending digital-asset infrastructure and open-source software need access to the latest AI capabilities to perform comprehensive security reviews and stay ahead of increasingly sophisticated adversaries. The coalition includes open-source development organizations, major custodians, treasury companies, payment services, security firms, capital allocators, and others whose businesses and customers depend on the integrity of open-source infrastructure and libraries. Open-source defenders often occupy the least privileged position in the AI security landscape. They have limited access to the strongest internal cyber models and are frequently blocked by guardrails when using publicly available frontier systems for legitimate security research. As a result, they often resort to less capable open-weight alternatives. We are urging frontier AI labs to establish a clear, trusted pathway for qualified open-source and digital asset defenders to access their strongest capabilities, with sufficient compute and secure environments to conduct meaningful security reviews. Frontier AI could become one of the most powerful defensive technologies ever developed, but only if defenders get fair access to those systems. It’s time to give defenders the tools they deserve.

In P2Poolv2, we always propagate stales, aka uncles. This helps with nodes being up to date with the DAG, so that if/when a fork happens, nodes already have the blocks for the other forks. We needed this to sync uncles etc, so the machinery was already there for stales too. Great to see stales being acknowledged here too! #JusticeForStales# 😉

With the help of @ajtowns, Localhost team members @pseudoramdom and w0xlt have sent a draft BIP on the staletip network message to the ML! Check out the proposal, review the PoC, and share your feedback:
