Coinbase lays out plan for a quantum-safe Bitcoin
- —Coinbase wants address design decoupled from signature method so cryptography can change without redesign
- —Options include BIP-360 (P2MR), P2TRv2 and hybrid addresses spendable with either signature type
- —Signature candidates: ML-DSA, SLH-DSA, FN-DSA (Falcon) and experimental SHRINCS
- —Migration path: voluntary adoption, hybrids, restrictions on old addresses, then rules for unmoved coins
Why it matters: As one of Bitcoin's largest custodians, Coinbase is shaping the framework for quantum migration that will affect institutional security and compatibility.
