ChainCatcher 消息，a16z crypto 研究团队今日发布开源 zkVM Jolt 的新版本 Lattice Jolt。该版本架构与此前版本相同，但将底层密码学从椭圆曲线改为格，同时实现后量子安全性、证明者与验证者速度提升 2-3 倍，以及证明大小低于 100 KB。
Lattice Jolt 用基于 Module-SIS 假设的新多项式承诺方案 Akita 替换此前依赖椭圆曲线的 Dory，目标完整 128 位安全性。Akita 由 LayerZero 研究人员与工程师主导开发，并与卡内基梅隆大学、南加州大学以及 a16z crypto 团队合作。在同一机器上，仅 CPU 的 Lattice Jolt 证明超过 200 万 RISC-V 周期/秒，Apple Metal GPU 加速下超过 1000 万周期/秒，证明者空间降至每周期约 200 字节。
