Why it matters

What signed receipts changes

  • Each decision comes with a signed receipt.
  • The evidence pack says who, what, when and why.
  • Change any field and the signature breaks.
  • Evidence is pulled together by hand when someone asks.
  • Who approved what is spread across several tools.
  • Nothing ties an answer to the exact request.

The resultEvidence made as the decision happens.

What you get

Signed receipts, in practice

  • Signed

    A receipt cannot be changed without breaking its signature.

  • Evidence pack per request

    The data, the rule, the reviewer and the result in one bundle.

  • Hashes over the plain text

    Hashes are taken over readable data, so proofs still verify when stored data is encrypted.

Questions

About signed receipts

Can I export receipts?

Yes, through the API, or streamed to your own log system.

Do receipts include private data?

They hold what you chose to send. Retention rules can redact it later without breaking the proof.
