Brink

Michael Ford (@fanquake) presented an update on his multi-year effort to ship fully static bitcoind binaries:

- Static vs dynamic linking
- Splitting Guix builds
- Running on older systems
- Open questions
- An experimental LLVM-only toolchain
- Why not macOS and Windows
- Q&A

Brink grantee @conduition_io presented on the state of post-quantum Bitcoin research:

- Post-quantum output types
- Quantum canaries and tripwires
- Freezing, ignoring, or rate-limiting Satoshi-era coins
- Rescue protocols
- Hash-based, lattice, isogeny signature schemes
- Q&A

We are excited to announce that Martin Zumsande (@lightlike1) has (re)joined Brink to continue his work on Bitcoin Core including P2P networking, validation, testing, and review!

Thank you @ColeMacro and @Strive for supporting Brink and open source Bitcoin development!

Reproducing rare bugs found during fuzz testing is hard because software can run slightly differently every time. Bedrock is a hypervisor that controls that randomness, so given the same inputs a program runs identically on every execution...
