【Change the lock, don’t rebuild the whole building】 🔐 If changing a door lock required construction across the entire building, how many people would need to coordinate for a security upgrade? 🧩 This is precisely how I understand Starknet’s native account abstraction: accounts themselves are smart contracts, and “what counts as a valid signature” can be defined within the account’s verification logic. In the future, when adopting a new post-quantum signature verifier, developers can create new account implementations without forcing a network-wide hard fork for every signature type. As cryptographic schemes evolve, allowing accounts to update their rules provides a flexible path for adaptation. 🔍 But flexibility doesn’t mean automatic completion. Upgrading old accounts, how wallets sign, how keys are stored, and how recovery permissions are configured—all require someone to deliver and audit the product. As of October 25, 2026, what I value is this adaptable mechanism, not the conclusion that “all wallets are quantum-safe.” Being able to change the lock is just the beginning; the final step is ensuring users can safely and reliably use it. @Starknet
