Bitcoin Community Moves Towards Consensus on Quantum Threat Mitigation

The Bitcoin community is shifting towards a consensus on addressing quantum computing threats, according to Galaxy Digital's Director of Research, Alex Thorn. As quantum computing hardware advances, the community is focusing on gradually introducing post-quantum cryptography (PQC) through soft forks to upgrade the address system and ensure long-term security. According to ChainCatcher, the current Bitcoin signature mechanism, which uses elliptic curve digital signature algorithms, is theoretically vulnerable to Shor's algorithm. Approximately 2 million BTC in early p2pkh addresses are at risk due to exposed public keys, facing potential 'collect now, decrypt later' threats. The community is considering a 'migration window' mechanism to guide users in transferring assets to new quantum-resistant addresses. Assets not migrated within a multi-year grace period may be frozen or destroyed to prevent market shocks from mass sell-offs in extreme scenarios. Additionally, there is consensus on enhancing 'crypto agility,' allowing protocol changes without network disruption. The current approach favors a dual-signature mechanism using both ECDSA and PQC, such as Dilithium, to ensure security redundancy and smooth transition. Analysts believe this strategy will transform the quantum threat from a 'black swan event' into a manageable technical upgrade, reinforcing Bitcoin's security as a long-term value storage asset.
