Adam Back advocates for quickly advancing optional quantum-resistant upgrades for Bitcoin and opposes preset freezing of vulnerable addresses.
Deep Tide TechFlow News, April 16, According to CoinDesk, Blockstream CEO Adam Back stated at Paris Blockchain Week that Bitcoin developers should proactively advance optional quantum-resistant upgrades, even though practical quantum computers are still far from realization. He pointed out that Taproot’s flexible design can support the introduction of new quantum-resistant signature schemes without affecting existing users.
Previously, Jameson Lopp and others proposed BIP-361, aiming to gradually phase out addresses vulnerable to quantum attacks within five years and freeze uncompleted Bitcoin migrations. Adam Back believes that the Bitcoin community can coordinate a rapid response in emergencies without the need for pre-set freeze arrangements.
