Sui Devnet Completes Native Quantum-Resistant Signature Transaction Test, Aims for Mainnet Account Authentication in Q1 2027

Odaily News: Kostas Chalkias, Chief Cryptographer at Mysten Labs, the core development company behind Sui, announced that the Sui Devnet has completed testing of native quantum-resistant signature transactions. The latest version now supports ML-DSA-65 post-quantum signature verification, which will be used for transaction authorization of regular accounts in the future. Additionally, there are plans to introduce SLH-DSA-SHA2-128s signatures through Move smart contracts to provide protection for high-value asset vaults.

Existing accounts will be able to derive quantum-resistant keys from their original mnemonics and update authorization keys through the address alias feature without needing to transfer assets. Sui plans to deploy quantum-resistant vaults to mainnet by the end of 2026 and introduce native ML-DSA-65 accounts to testnet, with the goal of achieving native account authentication on mainnet in Q1 2027. The specific timeline depends on security audits and testing results.
