@robin_linus Nice. That reminds me of a similar testnet tx (without the hashing in the redeem script though): mempool.space/testnet/tx/c6c… bitcointalk.org/index.php?topi…

Many of you have waited for a SHA2 hash that is also a valid signature. Finally, the wait is over:

A new release candidate of Bitcoin Core, v31.0rc1, is available for testing. This is a new major release, and follows v30.2. Work-in-progress release notes are here: github.com/bitcoin-core/b… Binaries are available here: bitcoincore.org/bin/bitcoin-co…

An impementation of BIP 54 "Consensus Cleanup" has been merged by @ajtowns into Bitcoin Inquisition: github.com/bitcoin-inquis…. @darosior continues to push this important work forward.

New BIP number assignment: BIP445: FROST Signing Protocol for BIP340 Signatures

Thanks @glozow for driving the package relay project for five years and to a good conclusion. Bitcoin users and especially Lightning Network users owe you a lot for your hard and admirable work.

I've opened a pull request for the FROST Signing BIP, aiming to standardize FROST signing for the Bitcoin ecosystem. If you've reviewed BIP327, this should feel very familiar. Would love to hear the community's feedback! github.com/bitcoin/bips/p…

Fuzzamoto is a fuzz testing tool for Bitcoin full nodes. For the last year, Niklas Gögge (@dergoegge) has been building Fuzzamoto with the goal of: “an external testing suite that gets as close as possible to taking production binaries as input and producing bugs as output”...

@OpenSats Nice, congrats @andrew_s_toth 🎉

The mempool is dead, long live the mempool github.com/bitcoin/bitcoi…

1 year later: we now have two compatible implementations supporting 0-fee channels (eclair and LDK) and the spec is final: github.com/lightning/bolt… Huge thanks to @glozow and @theinstagibbs who made it possible by working on mempool policy 🙏

🥕🥕🥕🥕 Happy Taproot activation anniversary! Taproot has now been active for four years!

Bitcoin Core now has an interface for its consensus code - it only took a decade. github.com/bitcoin/bitcoi…

You know what’s frustrating? When you’ve got the skills, the drive, and the ideas to make an impact, but the only thing stopping you is a border stamp. That’s the reality for so many brilliant Bitcoin developers across Africa and the Global South. They can write world‑class code, contribute to open‑source, and push the ecosystem forward, but collaborating in person with global peers or speaking on major stages? Too often, visa challenges make that impossible. We’ve decided that can’t be where the story ends. That's why we created the Pull Partnership; a way to place our grantees directly inside top Bitcoin teams around the world, where they can learn, share, and grow without barriers holding them back. The idea started when our grantee, @sadeeq_ismaela, joined @ChaincodeLabs in New York 🇺🇸 last year. He spent time working alongside leading Bitcoin developers, gaining hands-on experience and navigating the visa maze. That success made us think: what if we made this kind of opportunity a standard part of our grant ecosystem? Fast forward to this year. We’ve just piloted the Pull Partnership with @2140_dev in Amsterdam 🇳🇱. We’ve paired the Btrust‑funded developers with their team, covering salaries, relocation costs, and visa support, while 2140 provided mentorship, career development, and access to key Bitcoin industry events. We’d like to say a huge thank you to @josibake, @SomsenRuben and the @2140_dev team for making this partnership a reality.

Okay, v30.0 is tagged. Now that the [OP⏎ Debate|Bitcoin] is about to die, how about we pick something new to bash our heads in about? How about: - SENDTEMPLATE - TH+CSFS+IK - Consensus Cleanup - Great Script Restoration - Activate BIP 3 Links below.

Excited to share "Provable Cryptography for Bitcoin: An Introduction" - a comprehensive workbook that teaches formal security definitions and proofs through hands-on exercises. Solutions included!

One year ago Marco (@macrohead7) embarked on a year long Brink fellowship in our London office. Today, after a year of progress and contributions, we’re happy to bring him on as a full-time Bitcoin Core engineer…!
