Verum · Attest

The data authority for place.

Agents send a claim. We return a signed verdict on whether it corroborates against the record we hold. The signature is the product — verification is free, offline, and permanent.

The position

Data is copyable. A signature is not. Anyone can verify a receipt without us, which is exactly why the receipt is worth carrying: it names a snapshot, a claim, a verdict, and an issuer, and it cannot be forged.

Verum. The signature is the authority.
