Consensus: Quantum-Vulnerable
Why this rating. Validator authority keys use BLS12-381. Sui's quantum blog covers accounts and leaves consensus untouched; no consensus-layer post-quantum work found.
Transactions: Post-Quantum Ready
Why this rating. ML-DSA-65 verification code is merged behind protocol flag mldsa65_auth (PR 28413). Native accounts target Testnet by end of 2026 and Mainnet in Q1 2027. Not deployed.
Algorithms: ML-DSA
