Jolt: The zkVM Powering Zero
Jolt is the open-source RISC-V zkVM powering LayerZero's Zero chain, which replaces decades-old PCP-based SNARK approaches with sum-check protocol-based interactive proofs for fundamental efficiency gains. The design allows developers to prove existing programs without code changes or specialized circuits, with each instruction specified in approximately 10 lines of Rust. LayerZero's production implementation (Jolt Pro) achieves 1.61GHz per cell on CUDA GPUs with a roadmap to 4GHz by 2027, with a planned migration to lattice-based cryptography for post-quantum security.
