Optech's "Changing Consensus" monthly segment always makes for an interesting recap podcast View quoted note →

There is a lot going on in the OP_RETURN debate, but I definitely agree with this: "What the OP_RETURN debate has demonstrated is that Bitcoin Core and the Bitcoin technical community have not done a good job communicating their value – not to mention the rationale behind their decisions – to the average bitcoin user."

OP_RETURN debate: influencers vs. devs - Blockspace Media

The Bitcoin Core developers have produced artifacts and content on these matters already, but those of us closely observing need to do a better job of disseminating that information to a broader set of Bitcoin ecosystem participants. "The single biggest problem in communication is the illusion that it has taken place." I need to do better.

Is there a way to stream video via RTMP to nostr?

Which way, quantum Bitcoiner?

After years of contributing to Bitcoin on nights and weekends, Sebastian Falbesoner has left his job to focus 100% of his time on Bitcoin open source development. "After years of contributing part-time, I'm thrilled to fully commit myself to improving the Bitcoin ecosystem. A big thanks to Brink for providing the ideal environment to make this dream a reality! 🫡 " - Sebastian Brink is proud to enable Sebastian's move to full time, but the credit goes to our supporters. Thank you Samara Asset Group, Lightspark, Stakwork, Ledger, Bitwise, VanEck, and Jack Dorsey whose multi-year pledges show engineers that open source development can be a sustainable career!

Brink just received our first donation from a Bitcoin Donor-Advised Fund. The donation was in BTC and made using a multisig onchain transaction. This donation was made through Unchained's Bitcoin DAF and will be held in our reserves to fund Bitcoin development into the future. 🚀

Brink is excited to announce that Eugene Siegel has joined us as an open source engineer working on fuzz testing and Bitcoin Core development! With a background as a security engineer working on Lightning and already disclosing multiple Bitcoin Core security vulnerabilities, we're excited for Eugene to help ensure the long-term security, resilience & decentralization of Bitcoin. Welcome Eugene!

Whether that is the build system, operating system compatibility, the GUI, or language translations, hebasto’s efforts have been aimed at making Bitcoin secure, accessible, and user-friendly. Hebasto led a project to migrate the build system to a modern, CMake-based one, enhancing efficiency and paving the way for future development. The migration to CMake took nearly 300 pull requests, a dozen people, and two years of review and testing.
