This ultimately resulted in a change to GCC (thanks @MarcoFalke), which we’ll backport to the GCC we use to compile releases.

The Bitcoin Whitepaper is now available for people in the UK to read freely once again. The default judgement obtained fraudulently by Craig Wright has been overturned. Thank you to everyone who helped.

Today we announce the new disclosure policy the Bitcoin Core will adopt for most reported vulnerabilities.
We also publicly disclose 10 vulnerabilities affecting Bitcoin Core versions lower than 0.21.0.

In the beginning of June, it’s time for the citizens of the European Union to elect new Members of the European Parliament. Vote for candidates who stand up for privacy as a human right! 11/11

🇬🇧The verdict against Tornado Cash programmer @alex_pertsev criminalizes legitimate anonymity and all programmers who make it possible. We Pirates fight for digital freedom because freedom is the foundation of our society! More: patrick-breyer.de/en/convict…
ALT In the picture, MEP Patrick Breyer is depicted with the quote "Seeing freedom only in light of its abuse by some individuals curtails liberty and is an authoritarian way of thinking"
-ftrivial-auto-var-init=pattern in combination with Asan and UBsan may be a better sanitizer than Msan or valgrind, because it can even detect uninitialized memory reads before they are used to take a code branch.
Docker supports ipv6 out of the box now. :)

A Bitcoin Core ipv6-only CI system is not far away. Only @github is still stuck on ipv4-only.

The LTS program has a longer time horizon than regular grants, geared towards long-term stability for grantees.
The first recipient is @MarcoFalke, a long-term maintainer and contributor of Bitcoin Core with thousands of contributions over many years. 🫡

If you think OSS licenses matter and devs should be free to contribute w/o fear of multi-million-$ SLAPP lawsuits, this case matters.
It says bitcoin on the tin, but it’s about all of OSS. And yes it’s really costing millions to defend the MIT license.

We've seen both recent LLVM and GCC versions heavily "optimize" standard constant-time tricks (e.g. creating bitmasks from booleans) into branches.
We use valgrind tests to catch these cases, but I worry that other code bases are affected by recent compiler improvements as well.

Guix's main branch and its entire package base can now be built from a 357-byte auditable program: a Full-Source Bootstrap.
This means the first step I mentioned here: nitter.cf/carl_dong/status/15222… is now complete, and looking at the blog post there's active work on the second.

We are concerned that language in the proposed European Cyber Resilience Act may cause problems for public open source repositories like the ones we host. Please read and share: pyfound.blogspot.com/2023/04…
I have been the quality assurance and testing maintainer of Bitcoin Core for about 7 years now. In a challenging decision, I concluded to transition out of my role as maintainer. 🧵
I remain passionate about open source and Bitcoin and I am positive about the future, however being a maintainer is no longer a good fit for me personally. I am happy about my achievements and recognize that they would not have been possible without my sponsors.

Coincidentally, coverage about #bitcoin core devs in the WSJ today.
While it's positive to highlight how open-source development works, not sure I agree with the whole "mysterious control" angle.
The work is extremely public, and ultimately nodes need to run the code.
Bitcoin's value rests partly in the hands of six little-known developers who are selected by their peers and paid by a loose network of donors. They're often vague about their whereabouts. on.wsj.com/3S8r6F0
Thank you @Okcoin, a long time sponsor of my full time work on Bitcoin Core, and @paradigm for partnering on the renewed grant.
I like that @Okcoin pays me directly in #Bitcoin, which I can spend without extra hops at all businesses accepting LN⚡ or BTC.
We're excited to announce that we've partnered with @paradigm for the renewal of our grant to @MarcoFalke, one of #Bitcoin core's maintainers!
