I looked closer at @Starknet and the most interesting part of their quantum work right now is a version that is already on mainnet. With v0.14.3 the OS program and configuration hashes moved from Pedersen to a BLAKE2s-256 based construction. This is live, not a testnet experiment and not a future promise. It does not mean Starknet is fully quantum safe. State commitments, contract address derivation, account signatures and the Ethereum facing pieces still need separate work. Cryptographic migration is a series of scoped changes, each with its own implementation and evidence, not one overnight upgrade. One piece has shipped. Others stay on the roadmap. Starknet already has a structural edge here because STARKs rely on hash based cryptography and native account abstraction lets signature schemes change without a hard fork. Falcon-512 accounts have also been demonstrated on mainnet. That feels like a clearer story than another quantum security headline. The @KaitoAI Studio campaign runs until November 9.
