Frequently asked questions

AI agent receipts vs signed attestations

Signed attestations can bind a statement to a signer. A receipt adds execution context, observed output, and a review path. The two formats can complement each other, but neither proves an outside result that was never observed.

What can a verifiable receipt prove?

It can show what the execution layer recorded and what its integrity checks verify. It cannot prove an unobserved outside outcome.

How can another reviewer check the record?

Open the public receipt, compare the tool, time, result, and status, then call the verifier. Keep outside confirmations separate from the execution record.
