Coinbase outlines post-quantum upgrade concept for Bitcoin
- —Two paths proposed: BIP-360 (P2MR) with a new address type and P2TRv2 supporting quantum-resistant signatures
- —Candidate algorithms: ML-DSA, SLH-DSA, FN-DSA (Falcon) and SHRINCS
- —Main trade-off is signature size, which consumes more block space and could raise fees
- —Migration laid out in five stages, from voluntary upgrades to restrictions on legacy addresses
Why it matters: Millions of BTC sit on addresses with exposed public keys, so the choice of signature scheme shapes Bitcoin's long-term security.
