Sui Devnet processes first quantum-safe transaction with ML-DSA-65 integration

Sui’s Devnet blockchain has completed its first native quantum-resistant transaction, as Mysten Labs integrated the ML-DSA-65 digital signature algorithm into the network. This move marks a significant step toward building post-quantum authentication capabilities directly onto the Sui blockchain, with native account authentication on Mainnet scheduled for the first quarter of 2027, pending successful security audits and additional testing. Kostas Chalkias, co-founder and chief cryptographer at Mysten Labs, revealed that the initial quantum-safe transaction was executed successfully and its on-chain record shared with the community.
