Create a real proof and verify it — right here in your browser. No signup, no API key, no install.
This is live. Every proof created here hits the production protocol, gets a real deal ID, and enters the transparency log. You can export and verify the result offline, forever.
Enter a description of the work being proven. This gets hashed into the proof bundle.
Download the portable proof bundle for your deal. This bundle is self-contained and verifiable offline.
Run cryptographic verification against the proof bundle. This checks hash integrity, event chain ordering, and Merkle inclusion.
You created a real, production-grade proof with no signup and no API key. The proof is now:
