a16z crypto releases Lattice Jolt: The first high-performance post-quantum zkVM based on lattice cryptography
According to an official post from a16z crypto, a16z crypto has officially released Lattice Jolt, a new version of its open-source zkVM (zero-knowledge virtual machine) that fully transitions its underlying cryptography from elliptic curves to a lattice architecture, achieving post-quantum security while significantly boosting performance.
Key highlights include:
• Performance improvement: Proof generation speed increased by 2-3 times, reaching up to 2 million RV64IMAC cycles per second in CPU mode, and breaking through 10 million cycles per second with MacBook GPU acceleration (Apple Metal);
• Smallest proof size: Proof footprint is under 100 KB, significantly outperforming other post-quantum zkVMs with sizes ranging from 200 KB to 600 KB;
• Memory optimization: Memory consumption per cycle reduced from approximately 300 bytes to 200 bytes, supporting proof generation for millions of RISC-V cycles on mobile devices;
• Security: Based on the standard Module-SIS assumption, providing a complete 128-bit security strength, sharing the same assumption framework as ML-DSA and ML-KEM;
• New commitment scheme: The Akita polynomial commitment scheme, jointly developed by LayerZero in collaboration with institutions such as Carnegie Mellon University and the University of Southern California, replaces the original Dory scheme.
a16z crypto also pointed out that hash-based SNARKs are widespread...
