According to Decrypt, Blockstream CEO Adam Back stated at Paris Blockchain Week that he supports advancing Bitcoin’s quantum resistance upgrade on an opt-in basis, opposing proposals to forcibly freeze quantum-vulnerable addresses. He emphasized that “preparation well in advance is far safer than scrambling to respond during a crisis,” and noted that the Bitcoin community possesses strong coordination capabilities to rapidly address critical vulnerabilities. Previously, developer Jameson Lopp and five others proposed BIP-361 (“Post-Quantum Migration and Legacy Signature Sunset”), which advocates phasing out quantum-vulnerable addresses over five years and ultimately freezing coins held in unmigrated addresses—including approximately 1.7 million bitcoins held by Satoshi Nakamoto.
According to CoinDesk, Adam Back, CEO of Blockstream, stated at Paris Blockchain Week that Bitcoin developers should move forward early with optional post-quantum upgrades—even though practical quantum computers remain far from realization. He noted that Taproot’s flexible design supports integrating new post-quantum signature schemes without affecting existing users. Previously, Jameson Lopp and others proposed BIP-361, aiming to phase out quantum-vulnerable addresses over five years and freeze bitcoins in addresses that fail to complete the migration. Adam Back believes the Bitcoin community can rapidly coordinate a response in an emergency—without needing to predefine freezing arrangements.
