Fully-static, reproducible, release binaries for Bitcoin Core, have been a long-time goal of mine, and we are getting are closer to making them a reality. I've produced test binaries from a PR of mine (#25573), and am looking for feedback, questions, and hopefully testing on

Today is the feature freeze for the 0.21.0 release. The Taproot implementation, libsecp256k1 endomorphism, Tor v3 support, BIPs 155, 157, 158, Descriptor wallets (using SQLite), initial C++17 migration work and much more has made it in.

Release schedule for 0.21.0 · Issue #18947 · bitcoin/bitcoin

The Bitcoin Core development process and distribution model actually makes it somewhat harder to fix security issues, compared to other serious software distributors. Take Google Chrome as an example. The CVE fixing happy path is to develop and review a fix in private, push that

Replying to @adam3us

They can always push security fixes in v29 like any serious software distributor does, not forcing anyone to upgrade to unwanted/unprepared for functional changes… and I should know I work for a software editor for 15+ years

Truly crazy that 10s of thousands of people, and trillions in capital, aren’t quickly and easily coming to unanimous agreement over changing a global protocol for value exchange. Could be a feature

Bitcoin, a $2T ecosystem based on software, can't reach consensus on 9 lines of code needed to allow more and better scale (op_CAT). And it can't agree, for past 4 years, on any other minor change/update. Pretty insane.

This upgrade is a downgrade in security. 27.x is unpatched against CVE-2024-52919, as well as anything not-yet-disclosed, fixed in Core v28.x or v29.x. You should run whatever you want, but I'd advise against publicly announcing switching to software that can be crashed remotely.

Just upgraded my node from Bitcoin Core to Bitcoin Knots. Running (v27.1.knots20240801 via Docker). 😙 You can't stop all spam on the blockchain. But you can choose not to relay BS.

In ~2 weeks from now, we'll be disclosing 5 low severity vulnerabilities. We'll also shortly be releasing v29.2 & v28.3. The 27.x branch has now reached its end of li fe.

If you've never taken part in Bitcoin Cores release process before, now is a great first time to get involved. The v23.0 release has just been tagged, and so far 13 people have submitted attestations for their reproducible builds.
