Sui Completes First Native Post-Quantum Transaction on Devnet

Summary

Sui completed its first native post-quantum transaction on devnet, using ML-DSA-65 as the account signature, corresponding to Sui protocol version 139, without changing the consensus layer. ML-DSA-65 is a NIST-standardized lattice-based signature (FIPS 204, NIST Level 3), with a hash-based SLH-DSA-…

Key points

Developers wanting to understand practical blockchain post-quantum migration can see signature choices, key rotation, and timeline.
Post-quantum cryptography is moving from research to account-layer implementation, a key foundational engineering effort for long-term blockchain security.
Wallet and SDK developers need to plan ahead for larger signatures and key rotation processes to prepare for future mainnet upgrades.
