1月15日消息，随着量子计算长期风险逐步被加密行业正视，OP Labs 正式公布“超级链后量子安全路线图”，明确提出将在未来10年内逐步淘汰基于 ECDSA 的外部账户（EOA），为以太坊生态和 OP Stack 构建量子弹性基础设施。
OP Labs 指出，大规模量子计算机虽然尚未落地，但一旦现有密码学体系被突破，签名与承诺机制失效将对以太坊和超级链造成系统性冲击。因此，提前规划后量子（Post-Quantum，PQ）迁移已成为必要选择。得益于 OP Stack 的模块化架构，核心签名方案可通过硬分叉完成替换，无需重构底层系统。
根据规划，在获得治理批准的前提下，到2036年1月，OP 主网及整个超级链将停止接受 ECDSA 签名的 EOA 交易。所有现有 EOA 将需要把密钥管理权限迁移至支持后量子签名的智能合约账户。这一过程将依托账户抽象机制推进，OP Stack 已支持 EIP-7702，使用户无需更换地址或转移资产即可完成升级。
在过渡期内，EOA 可逐步将交易授权委托给验证后量子签名的智能账户；窗口期结束后，协议层将只接受支持 PQ 的账户路径。具体采用哪种后量子签名方案尚未最终确定，OP Labs 表示将持续评估 NIST 标准化方案，并通过可升级的智能账户设计保持灵活性。
除用户层面外，OP Stack 还计划升级序列器和批量提交器，从 ECDSA 签名过渡至后量子算法，并在整个超级链范围内同步实施。在更高层级，OP Labs 也呼吁以太坊社区为验证器的 BLS 签名和 KZG 承诺制定长期的后量子迁移时间表。
OP Labs 强调，本次公告旨在提前设定预期，而非立即执行变更。未来将为基于 OP Stack 构建的钱包、基础设施和应用提供明确的迁移指南和工具，确保超级链在迈向后量子时代的过程中平稳、安全地演进。
