TechFlow News: On April 16, according to CoinDesk, Adam Back, CEO of Blockstream, stated at Paris Blockchain Week that Bitcoin developers should move forward promptly with optional post-quantum upgrades—even though practical quantum computers remain far from realization. He noted that Taproot’s flexible design enables the introduction of new post-quantum signature schemes without disrupting existing users.
Previously, Jameson Lopp and others proposed BIP-361, aiming to phase out quantum-vulnerable addresses over five years and freeze bitcoins remaining in unmigrated addresses. Adam Back believes the Bitcoin community can rapidly coordinate a response in an emergency, without needing pre-defined freezing arrangements.
