Techub News reports, according to Cointelegraph, Layer 1 network BNB Chain released a report indicating that post-quantum cryptography upgrades could lead to increased transaction data size, thereby reducing network throughput by 40% to 50%. Post-quantum cryptography (PQC) aims to resist attacks from quantum computers, but the upgraded encryption algorithms typically require larger keys and signature sizes, which will increase the storage and transmission burden on the blockchain. As one of the mainstream public chains, BNB Chain's technical assessment provides an important reference for the industry regarding the trade-offs between quantum security and performance.
