# Trust Protocol

The Trooth Trust Protocol lets anyone holding a Trooth-signed observation check that Trooth produced it unchanged. Each carries a signing time Trooth asserts inside the signature, checkable against the [signing keys page](https://trooth.co/verify/keys).

Note

That signing time is Trooth's own statement: no third party records it.

## The specification

The full specification (token format, witness signature schema and reference checker) is available on request.

[Request the Trust Protocol Specification](https://trooth.co/security#document-request).

## Terms

Use of the Trooth Trust Protocol is subject to the [Terms of Service](https://trooth.co/terms).
