Getting ramped up as a new contributor in the FOSS Bitcoin ecosystem isn't easy. There is so much to do, so much to learn. In our effort to lift up and support the next generation, we are excited to announce our 2025 Visiting Scholar program! Over three months, our Visiting

Ava's ranting about Bitcoin Improvement Proposals from Taipei! 🇹🇼 Catch the stream at 4:07:00 to learn why your protocol belongs as a BIP:

64 Byte Transactions A 64 byte Bitcoin transaction has the potential to be confused with an intermediate hashing step in Bitcoin’s Merkle tree, because this is also 64 bytes. We explore how this vulnerability can be exploited & look at a proposed fix https://t.co/eTu2XiDXFv

Just added more block arrival timestamps from six nodes (~90k blocks each) to the CC0 1.0 licensed Bitcoin Block Arrival Time Dataset. We now have full timestamp coverage over the last 10 years 🎉 Thanks to everyone who has contributed so far! https://t.co/raKCKeJLz4

A truly world-class program. ₿OSS alumni have had a lasting impact on our organization. We are eternally grateful to the Chaincode team and all the partners and mentors who make ₿OSS possible.

@bitschmidty from @bitcoinbrink took the initiative to sponsor a security audit of Bitcoin Core. @dergoegge and i helped by providing guidance to @quarkslab's team. Read up more about it here:

If you’ve ever donated to Brink, you should scrutinise how we’re spending your funds. We’re working hard to maintain the Bitcoin codebase, and expanding our security and maintenance efforts. We’re raising to fund more fuzzing engineers and infra; now’s a great time to donate.

We've officially kicked off the #BtrustGathering 🚀 Over the next two days, we're bringing together grantees, engineers, contributors, faculty, community organizers, and ecosystem partners for a focused convening built around strategic alignment, cross-regional collaboration,

The work @murchandamus has done advancing BIP 3 has reached another milestone. BIP 3 is now ready for activation! Read his latest post on the mailing list for a summary of changes since BIP 3 entered the Proposed state, along with his call for activation:

Grateful for @murchandamus work on improving the BIP process

The importance of this work cannot be overstated. Capturing Bitcoin's consensus engine in this way is good not only for Bitcoin Core, but also for Bitcoin more broadly. Congrats to @the_charlatan_ for getting this PR merged, and many thanks to the contributors who reviewed,

Many thanks to the scribes, all who attended, the organizers, and the folks on-the-ground that helped us find a venue! Lots of great transcripts included for those who are interested in closely following the various active projects going on within and around Core.

My second CoreDev event It was engaging I met people I’ve been collaborating with. Discussed my work, learned from the giants. We hacked, reviewed, brainstormed, and had fun! Thanks @btrustteam @2140_dev 🧡 A tiny PR of mine at one of the session https://t.co/pxe90iNoZa

Updated statistics on compact block reconstructions from @0xB10C's Bitcoin network monitoring: "on 2025-09-17, I switched the nodes to run with a lowered minrelayfee. That’s also visible in both the reconstruction rate getting better and having to request a lot less data from

On Tuesday evening, we'll be hosting the monthly SF BitDevs Socratic Seminar at @Stanford in the Gates Building! The Seminar will be followed by two presentations, one from @msgilligan on secp256k1-jdk and another from @tonklaus on Stable Channels. Thanks to @danboneh for helping

What a journey it has been! And with much more to come. We are so excited to see what @sliv3r__ does next. But for time being, we’re monopolizing his time at the Localhost offices. At least until his Visiting Scholar program is done. 😉

Thank you for the kind words @miketwenty1! @tabconf 7 was incredible, and it wouldn't have happened without the efforts from you and the team. The BitDevs Socratic Village got a lot of great engagement and helped drive forward the conversations around mining centralization and

We had 12 members from the Vinteum community attending @tabconf, and even got to hang out with another BR Bitcoin Mafia member from @lclhostresearch. Five of them gave talks or workshops. Thank you, TabConf, for the great event!

Thank you David! It's an honor to have your support. We are so excited for the future of our organization and grateful to have you and @lightspark as members of the Localhost Family. ❤️

@lclhostresearch Awesome to see @lightspark support what matters. Kudos @davidmarcus
