Sui processes first quantum-safe transaction on Devnet

Sui's Devnet has executed its first native quantum-safe transaction using ML-DSA-65 post-quantum signatures, according to Mysten Labs co-founder Kostas Chalkias. The milestone marks the first on-chain verification of post-quantum cryptography on the network.

ML-DSA-65 support is now live in Devnet v1.82.0 with full API integration through ExecuteTransaction and VerifySignature endpoints. The signatures work in multisig transactions and are integrated into GraphQL and the Rust SDK.

Sui targets Mainnet deployment of native ML-DSA-65 accounts in Q1 2027, pending security audits. The move prepares the blockchain for quantum computing threats to current elliptic curve cryptography standards.
