a16z crypto introduced Lattice Jolt, a lattice-based zkVM replacing Dory with Akita. It achieves post-quantum security, 2-3x speedups, and sub-100KB proofs.a16z crypto团队在博客中发布Lattice Jolt，开源zkVM新版本，以格基承诺Akita替代椭圆曲线Dory，实现后量子安全，证明速度提升2至3倍，证明尺寸低于100KB。a16z cryptoチームがブログで、楕円曲線から格子暗号に移行したオープンソースzkVM「Lattice Jolt」を発表。耐量子性を実現し、証明速度を2～3倍に向上、証明サイズは100KB未満に抑えた。
NotesNotes要点
- Replaces elliptic-curve Dory with Module-SIS-based Akita for transparent post-quantum security
- Prover reaches 2M+ cycles/sec on CPU, 10M+ on MacBook GPU via Metal
- Proof size under 100KB, smallest among current post-quantum zkVMs
- Proving overhead dropped from millions to ~10,000x, memory to 200 bytes/cycle
- Highlights security risks of algebraic hashes and unproven proximity-gap bounds in hash-based SNARKs
- Maintains nearly 128-bit security over 128-bit fields, unlike hash-based soundness loss n/|F|
