Adam Back advocates for optional quantum resistance upgrades, differing from the mandatory freeze proposal of BIP-361

According to market news, Blockstream CEO Adam Back stated at the Paris Blockchain Week that he supports the optional advancement of Bitcoin's quantum resistance upgrade and opposes the proposal to forcibly freeze quantum-vulnerable addresses. He emphasized that "preparation is much safer than hasty responses in a crisis" and pointed out that the Bitcoin community has the coordination ability to respond quickly to urgent vulnerabilities.

Previously, the BIP-361 proposal ("Post-Quantum Migration and Legacy Signature Sunset") put forward by developers Jameson Lopp and five others advocated for the gradual elimination of quantum-vulnerable addresses over five years, ultimately freezing coins that have not completed migration— including approximately 1.7 million Bitcoins held by Satoshi Nakamoto.
