Coinbase Proposes Ways to Protect Bitcoin From Quantum Risks
Coinbase says Bitcoin’s shift to post-quantum security will take years and should start before quantum computers can break current signatures.
- On Tuesday, Coinbase urged Bitcoin developers to begin preparing for quantum computing threats, warning that upgrading the cryptocurrency's security could require years of coordination.
- Bitcoin currently relies on ECDSA and Schnorr signatures to authorize transactions; a sufficiently powerful quantum computer could theoretically derive private keys from exposed public keys, enabling unauthorized spending.
- Coinbase, which holds approximately 5% of existing BTC, identified BIP-360 and P2TRv2 as flexible designs worth considering, recommending evaluation of ML-DSA, SLH-DSA, and FN-DSA algorithms.
- Coinbase proposed a 1-of-2 construction for phased migration, emphasizing that large custodians require stateless signing to prevent operational failures during the transition.
- BIP-361, titled Post Quantum Migration and Legacy Signature Sunset, proposes gradually restricting older signatures, though developers must still address dormant or lost Bitcoin holdings.
