BSC 发布抗量子密码迁移报告，交易签名已切换至 ML-DSA-44，TPS 测试下降约 40%-50%
ChainCatcher 消息，BNB Chain 于此前 5 月 14 日发布《BSC Post-Quantum Cryptography Migration Report》称，已完成针对交易签名与共识层的抗量子密码迁移测试，采用 NIST 标准化后量子签名算法 ML-DSA-44（Dilithium）及 pqSTARK 聚合方案。
报告显示，BSC 已将交易签名从 ECDSA 替换为 ML-DSA-44，并将共识投票聚合从 BLS12-381 切换至 pqSTARK，以应对未来量子计算对现有椭圆曲线密码体系的潜在威胁。不过，后量子签名也显著增加链上数据体积：单笔交易大小从约 110 字节增至约 2.5KB；区块大小在 2000 TPS 场景下从约 130KB 增至约 2MB；测试环境下 TPS 下降约 40%-50%。
BSC 表示，当前网络瓶颈主要来自更大的交易数据传播，而非共识协议本身。与此同时，共识层聚合仍保持较高效率，pqSTARK 可实现约 43:1 的签名压缩比，验证者额外负担仍处于可控范围。报告认为，现有技术已可实现区块链“抗量子化”部署，但未来仍需解决网络带宽与数据扩展性问题。
