Sebastian’s next priorities are getting silent payments merged into libsecp256k1, activating the DLEQ module, reviewing BIP54 (the Consensus Cleanup), working on FROST threshold signatures and helping with the ongoing effort to remove libevent as a Bitcoin Core dependency.

How can we automatically test Bitcoin nodes with millions of different tests/day without changes to the software itself while considering non-deterministic factors like time &randomness? Niklas Gögge (@dergoegge) explores in part 2 of our Fuzzamoto series brink.dev/blog/2026/04/0…

Marco De Leon (@macrohead7) completed his transition from Brink fellow to full-time grantee, establishing himself as a capable contributor across multiple areas of the codebase. He drove the txid type safety project to completion across six pull requests, successfully removed Bitcoin Core's legacy checkpoints, left nearly 250 review comments, and contributed to fuzz testing infrastructure and P2P code review.
