BNB Chain cut throughput by 40% after post-quantum test

BNB Chain (BSC) don start run post-quantum cryptography test wey don really slow down how the network dey perform. For the BNB Chain post-quantum test dem change core signature and validator cryptography to quantum-resistant alternatives, and the reported throughput drop from 4,973 to 2,997 transfers per second (about −40%). The slow down na because quantum-ready digital signatures big and on-chain data too big. Transaction signatures climb from ~110 bytes to ~2.5 KB (about 23×), and average block size jump from ~130 KB to nearly 2 MB (about 15×). This one create steady bandwidth and propagation pressure, even though the validator confirmation layer no too feel am because of compression. Important be say dem frame am as research, no be live protocol upgrade, so immediate on-chain impact dem talk sey minimal. For traders, the main takeaway na short-term engineering uncertainty around BNB Chain scaling and possible fee dynamics as the ecosystem dey weigh stronger quantum security vs performance. Other networks dem also dey use phased approaches: Bitcoin dey plan long-term upgrades (e.g., BIP-360), Ethereum dey push post-quantum initiative through the Ethereum Foundation, and TRON don announce quantum-resistant testnet for Q2 2024 with mainnet rollout targeted for Q3.
