A16z crypto has released Lattice Jolt, an updated version of its open-source zkVM. The new architecture replaces elliptic-curve cryptography with a lattice-based approach to ensure resistance against potential quantum computing threats.
The system utilizes a new polynomial commitment scheme called Akita, developed by LayerZero, Carnegie Mellon University, and the University of Southern California. It operates under the Module-SIS assumption with 128-bit security strength, aligning with NIST standards.
Lattice Jolt delivers proving times 2 to 3 times faster than the previous version, with proof sizes ranging from 65 to 80 KB. Memory usage per cycle has been reduced from approximately 300 bytes to 200 bytes.
Performance metrics show the system achieves up to 2 million RV64IMAC cycles per second on a CPU, increasing to over 10 million cycles per second with GPU acceleration. The technology currently supports RISC-V instruction sets.
The Zero blockchain serves as the initial integration partner for the technology. A16z crypto has stated that this release is strictly an infrastructure development and does not include any associated token launch.
