Sui Network has successfully processed its first native quantum-safe transaction on devnet, marking a key milestone in post-quantum cryptography integration. Mysten Labs’ chief cryptographer confirmed that validators can now verify ML-DSA-65 signatures within the development environment. While the devnet now supports these advanced cryptographic standards, mainnet continues to reject ML-DSA-65 signatures as the network prepares for broader implementation. This testing phase allows developers to validate quantum-resistant infrastructure before any potential production deployment.
