Sui targets 2027 mainnet rollout for native quantum safe account authentication

Sui has added two NIST-approved post-quantum signature schemes to its blockchain roadmap as it prepares optional quantum-safe accounts and vaults for future network upgrades. Summary Sui plans to add two NIST approved post quantum signature schemes for accounts and smart contract vaults. Existing recovery phrases and wallet addresses can be retained when users move to quantum safe authentication. Quantum safe vaults are targeted for mainnet this year, with native accounts planned for testnet by the end of 2026. ML DSA 65 and SLH DSA are designed to protect different types of assets using separate cryptographic approaches. The announcement follows similar post quantum security work across Bitcoin custody, BNB Chain and other blockchain projects. According to Sui’s latest announcement, the blockchain plans to introduce ML-DSA-65 as a native signature scheme for regular accounts and SLH-DSA-SHA2-128s for high-value smart contract vaults, giving users an optional way to protect accounts against future quantum computing risks without replacing their recovery phrases or moving assets. The rollout comes as blockchain developers and infrastructure providers increasingly prepare for the pos...
