According to a report released by BNB Chain on May 14th, BSC has completed anti quantum cryptographic migration testing, replacing transaction signatures from ECDSA with ML-DSA-44 and switching consensus voting aggregation from BLS12-381 to pqSTARK. The size of a single transaction increased from 110 bytes to 2500 bytes, and the block size increased from 130KB to 2000KB in the 2000 TPS scenario. In the testing environment, TPS decreased by about 45%. The report states that the main bottleneck in the network comes from the propagation of transaction data, with a pqSTARK signature compression ratio of 43:1. The burden on validators is controllable, but bandwidth and scalability issues still need to be addressed.
