Wu said that BNB Chain released the "BSC Post-Quantum Cryptography Migration Report," stating that the feasibility of post-quantum cryptography schemes has been verified in testing. The scheme replaces transaction signatures with the NIST standard ML-DSA-44 and replaces consensus voting aggregation with pqSTARK, which can maintain existing 20-byte addresses, RPC, SDK, and wallet compatibility. However, testing shows that signature size increased from 65 bytes to 2,420 bytes, and block size in a 2,000 TPS scenario increased from about 130 KB to about 2 MB, with cross-region TPS dropping by approximately 40%. BNB Chain stated that data bloat-related network and data layer scaling issues remain the main challenges for production deployment.
