BNB Chain completes post-quantum cryptography migration testing

According to the report released by BNB Chain on May 14, BSC has completed quantum-resistant cryptography migration testing, replacing transaction signatures from ECDSA with ML-DSA-44 and switching consensus vote aggregation from BLS12-381 to pqSTARK. The size of a single transaction increased from 110 bytes to 2,500 bytes, and block size in a 2,000 TPS scenario grew from 130KB to 2,000KB, with TPS dropping about 45% in the test environment. The report states that network bottlenecks mainly stem from the propagation of transaction data. pqSTARK signature compression ratio reaches 43:1, making the validator workload controllable, but bandwidth and scalability issues still need to be addressed.
