Verify our claims yourself.

An evidentiary platform you have to trust is a contradiction. Everything TruthLayer asserts about a ledger can be checked by anyone, offline, using only public artefacts and open-source code.

What the verifier checks

  1. The daily seal’s Merkle root and signature, recomputed from the published seal artefact.
  2. The signing key: either a tenant root key generation, or a per-agent subkey whose certificate is verified against the tenant root that issued it — including its validity window.
  3. The OpenTimestamps anchor: the proof file that commits the day’s Merkle root into the Bitcoin blockchain, checkable with the standard ots verify tool.

No TruthLayer endpoint is contacted. The verifier reads a directory or URL of public artefacts and applies mathematics.

We dogfood this principle.

Every form submission on this site is HMAC-signed by the receiving edge function before it is forwarded anywhere, and the downstream automation verifies that signature before acting. Signed evidence at the network boundary applies to our own operations, not just our customers’.
