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 is excited to announce that Eugene Siegel has joined us as an open source engineer working on fuzz testing and Bitcoin Core development!
https://m.primal.net/QBty.png
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!

Today we celebrate Hennadii Stepanov's 4 year anniversary as a Bitcoin Core engineer at Brink 🎉
From a simple fixup because of an old laptop, to one of the most prolific contributors to Bitcoin Core today...
https://brink.dev/blog/2025/03/28/hebastos-brink-epoch/
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.
https://bitcoinops.org/en/newsletters/2024/09/06/#bitcoin-core-30454
Since his initial contribution, hebasto has 1800+ (!) commits to his name.
But it isn't just his own work...in the last year alone hebasto also provided nearly 1,700 review comments.
https://github.com/bitcoin/bitcoin/graphs/contributors
Brink and the Bitcoin community are lucky to have hebasto on our team.
Thank you for your open source #Bitcoin contributions, Hennadii 🚀

Gloria Zhao, Niklas Gögge, and b10c discuss 3 recently announced Bitcoin Core vulnerabilities:
- DoS vulnerability in headers sync
- DoS vulnerability in inventory send queue
- Crash vulnerability in compact block relay
High severity:
An attacker could provide a peer with a chain of low-difficulty headers, which could be used to remotely crash the node.
Medium severity:
Increased network activity affected block and transaction propagation and dropped connections.
High severity:
An attacker could remotely crash Bitcoin Core nodes by triggering an assertion in the blocktxn message handling logic.
