BSC releases anti quantum cryptographic migration report: transaction signatures have been switched to ML-DSA-44, TPS testing has decreased by about 40% -50% According to BlockBeats, on May 19th, BNB Chain released the "BSC Post Quantum Cryptography Migration Report" on May 14th, stating that it has completed anti quantum cryptographic migration testing for transaction signatures and consensus layers, using NIST standardized quantum signature algorithm ML-DSA-44 (Dilithium) and pqSTARK aggregation scheme. The report shows that BSC has replaced transaction signatures from ECDSA with ML-DSA-44 and switched consensus voting aggregation from BLS12-381 to pqSTARK to address potential threats from future quantum computing to existing elliptic curve cryptography. However, post quantum signatures also significantly increase the on chain data volume: the size of a single transaction increases from about 110 bytes to about 2.5KB; the block size increases from about 130KB to about 2MB in the 2000 TPS scenario; and TPS decreases by about 40% -50% in the testing environment. BSC states that the current network bottleneck mainly comes from the propagation of larger transaction data, rather than the consensus protocol itself. At the same time, consensus layer aggregation still maintains high efficiency, and pqSTARK can achieve a signature compression ratio of about 43:1, while the additional burden on validators is still within a controllable range. The report suggests that existing technologies can achieve "anti quantization" deployment of blockchain, but network bandwidth and data scalability issues still need to be addressed in the future.
