ZEE200: Zero Knowledge for Everything and Everyone @ 200 KHz

Paper

https://eprint.iacr.org/2026/828

Sunghyeon Jo zkVM Constant-Round

Jo et al. proposed ZEE200, a constant-round ZK system achieving 200 KHz CPU speed on a commodity laptop, supporting a richer ISA and improving over ZEE by ~4000%, demonstrated by proving CVE vulnerabilities in Linux programs.

Notes

ZEE200's performance boosted by about 4000%, increasing from ZEE's 50 KHz to 200 KHz.
ZEE200 runs on a standard laptop (2021 ThinkPad X1 Carbon Gen 9) and in a simulated LAN environment.
Supports a richer instruction set, with arithmetic encoding optimizations and extensive low-level improvements.
Integrates the latest advances such as Tight ZK CPU (CCS'24) and fast ZK RAM (USENIX Security'24).
Benchmark: proving Linux tool CVE vulnerabilities drops from several seconds (ZEE) to sub-second (ZEE200).
ZEE200 provides an efficient and practical zero-knowledge proving toolchain for general-purpose programs.

What is the main goal of ZEE200?

ZEE200 aims to enable efficient zero-knowledge execution of general programs, allowing arbitrary computations to be proven correct while preserving input privacy.

What key techniques does ZEE200 build on?

It builds on techniques like Tight ZK CPU and fast ZK RAM to efficiently represent instruction execution and memory access for general-purpose proofs.

Why does ZEE200 achieve significant performance gains?

It improves arithmetic encodings, optimizes the CPU execution model, and integrates efficient ZK components, reducing per-step proof cost and increasing throughput.
