TechFlow News, April 16: 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, while opposing proposals to forcibly freeze quantum-vulnerable addresses. He emphasized that “preparing 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.
