Proof you can check. Verify the receipt.
Paste any Trustvice signed receipt — a Proof-of-Erasure, an Oversight receipt, a Verifiable Invoice, a Charter Attestation, any of the 22 kinds. This tool fetches our published Ed25519 keys and checks the signature in your browser. It never calls Trustvice for the answer, so the result is one anyone can reproduce.

Honest scope
What this proves — and what it doesn’t.
What it confirms
The receipt was signed by the Trustvice key it names, and its contents (subject + claims) have not been altered by a single byte since. The verdict is computed locally from our published keys — you never take our word for it.
What it doesn’t
A valid signature proves integrity + origin, not that a self-asserted claim inside is true. Where a receipt embeds an observed assertion (e.g. a charter’s conformance counts), it says so; the signature binds it to a key + time, nothing more.
