Wu Blockchain (@WuBlockchain): BSC Post-Quantum Upgrade Passes Test, but TPS Falls 40%

BSC Post-Quantum Upgrade Passes Test, but TPS Falls 40% BNB Chain released its BSC Post-Quantum Cryptography Migration Report, saying BSC has tested a post-quantum upgrade using ML-DSA-44 for transaction signatures and pqSTARK for consensus vote aggregation. The design remains compatible with existing addresses, RPCs, SDKs and wallets, but testing showed major data overhead: signature size rose from 65 bytes to 2,420 bytes, and cross-region TPS fell by about 40%. BNB Chain said network and data-layer scaling remain the main challenges before production deployment.
