BNB Chain has released its "BSC Post-Quantum Cryptography Migration Report," confirming the feasibility of post-quantum cryptography solutions in testing. The report details the replacement of transaction signatures with the NIST standard ML-DSA-44 and consensus vote aggregation with pqSTARK, while maintaining compatibility with existing 20-byte addresses, RPC, SDK, and wallets. However, tests revealed that signature sizes increased from 65 bytes to 2,420 bytes, and block sizes in a 2,000 TPS scenario grew from approximately 130 KB to about 2 MB, with cross-regional TPS dropping by around 40%. BNB Chain noted that the challenges of network and data layer expansion due to data inflation remain significant for production deployment.
