ZisK is an open-source zero-knowledge proving toolstack featuring a zkVM that enables verifiable execution of programs written in high-level languages like Rust.
- ZisK is low-latency by design, distributed by nature.
- ZisK controls the full inhouse full stack. This allows to have many optimizations that affects the whole architecture.
- Targeting 128 bits security.
- ZisK is the Fully Open Source (including GPU code) project. You can integrate in your own infrastructure.
- RiscV 64 bit architecture. Rust, golang, C#, etc.
- ZisK stack is modular and can allow other VMs like wasm or native LLVM
Initially incubated by Polygon Labs from May 2024 to June 2025, ZisK became an independent project on June 13, 2025. Its intellectual property, the core team and all its knownledge were transferred to SilentSig Switzerland GmbH, a company fully owned by Jordi Baylina (@jbaylina).
The team remains fully committed to advancing ZisK as a community-driven, open-source project (under MIT/Apache 2.0 licenses), ensuring continuous improvement and maintenance.
We invite all developers and projects to test, contribute to, and use ZisK. Our goal is to build the reference zkVM project in the space.
