Q-Day won’t be the right time to start preparing. Why? Because upgrading cryptography across an entire blockchain ecosystem takes time. @tezos is already preparing for the post-quantum transition. The work involves more than replacing an algorithm: 1/ Select and implement new cryptographic standards. 2/ Upgrade wallets and applications. 3/ Update baker keys and signing systems. 4/ Test security, compatibility and performance. 5/ Coordinate governance and educate users. 6/ Plan how existing assets and accounts will migrate. The challenge isn’t just developing quantum-resistant cryptography. It’s deploying it safely across an entire ecosystem. Tezos’ post-quantum research and experimental initiatives reflect the importance of preparing before quantum computers pose a real cryptographic threat. The goal isn’t to predict Q-Day. It’s to reduce the risk of being unprepared. Which part of the transition do you think will be hardest for Tezos and other blockchains to coordinate: wallets, bakers or user migration?
