ChainCatcher 消息，Sonic 详解其面向 “后量子时代” 的技术路径，指出当前多数 PoS 公链依赖椭圆曲线签名（如 ECDSA、Ed25519），在量子计算（如 Shor 算法）成熟后存在被破解风险。
Sonic 表示，行业正探索抗量子密码方案（如基于哈希的 XMSS、SPHINCS+ 及基于格的 Dilithium、Falcon），但主流共识机制普遍依赖 BLS 聚合签名与阈值签名，迁移至抗量子体系将面临性能、带宽及架构重构等挑战。相比之下，Sonic 的 SonicCS 共识协议不依赖聚合签名或全局随机性，仅使用单节点签名与哈希函数构建 DAG 结构。因此在切换至抗量子密码时，仅需替换签名算法即可完成升级，无需调整共识逻辑或网络结构。Sonic 强调，该设计将显著降低未来向抗量子安全迁移的复杂度，使网络在量子计算威胁到来时具备更强的适应能力。
