ml-dsa-65

Mysten Labs reports that the Sui network has completed its first native post-quantum Devnet transaction. This Devnet implementation introduces the ML-DSA-65 account signature, allowing accounts to authorize transactions directly using this post-quantum signature scheme. ML-DSA-65 belongs to the ML-DSA series defined by the National Institute of Standards and Technology (NIST) FIPS 204 standard, and Sui uses it as the native protocol signature scheme for everyday accounts.Sui is also planning to introduce a hash-based SLH-DSA-SHA2-128s (FIPS 205) for high-value vaults in Move smart contracts. The two schemes are based on lattice-based and hash-based mathematical problems, respectively, so a weakness in one scheme will not affect the other. Since Sui keys are deterministically derived from seeds, users can migrate to post-quantum keys using existing mnemonic phrases; the already launched address aliases allow accounts to update authorization keys without transferring assets.Post-quantum accounts are being rolled out in an optional, incremental manner, following the online path of zkLogin and passkey. Sui states that the goal for the post-quantum vault is to go live on the mainnet within this year, with the native ML-DSA-65 accounts aiming to enter the testnet by the end of the year, and the mainnet native account authentication goal set for the first quarter of 2027, with the final timeline depending on independent audits and testnet feedback.
