BNB Chain has successfully completed its migration to post-quantum cryptography, as detailed in its recent report. The blockchain has adopted the NIST-standardized ML-DSA-44 algorithm for transaction signatures and pqSTARK for consensus vote aggregation, replacing the previous ECDSA and BLS12-381 systems. This shift aims to protect against future quantum computing threats but has resulted in a significant increase in on-chain data size. The migration has led to a substantial increase in transaction and block sizes, with a single transaction size growing from 110 bytes to 2.5 KB and block size expanding from 130 KB to 2 MB under a 2000 TPS scenario. Consequently, the network's transaction processing speed has decreased by 40%-50%. Despite these challenges, the pqSTARK aggregation scheme maintains high efficiency, achieving a signature compression ratio of 43:1, which helps manage the additional load on validators. The report highlights that while quantum-resistant blockchains are feasible, issues related to network bandwidth and data scalability persist.
