Watch a real record verify, end to end

No record to hand? The sample is a real, self-contained record. It is re-hashed and checked in your browser, content and all, and lands on the same VERIFIED readout any record does.

Zero-trust path

Verify offline, forever

This page runs in your browser, but you do not have to trust even that. The offline verifier is one self-contained file: no network, no server, nothing to install. Download it, check its SHA-256 against the published trust root, and verify any record on your own device, today or in ten years. The specification and the conformance vectors are published as well, so you can re-implement the verifier yourself and prove your build agrees, without trusting our code at all.
