Brink grantee conduition presented a map of the post-quantum Bitcoin landscape to Brink engineers, focusing on how the various proposals interact with each other.

In his presentation, he discussed:

  • Trade-offs between post-quantum output types like P2MR (BIP360), P2TR v2, and P2TR hash
  • Quantum canaries and tripwires as on-chain oracles for Q-day
  • Freezing, ignoring, or rate-limiting Satoshi-era coins with proposals like Hourglass
  • Rescue protocols using commit/reveal or zero-knowledge proofs
  • Hash-based (SHRINCS), lattice-based, and isogeny-based signature schemes
  • Elliptic curve optimizations like cross-input signature aggregation (CISA) and public key recovery
  • Q&A with the audience
