USE CASE 03

Audit · long-term retention · retired services

Recheck the original record
after the live system is gone

Package the material required for verification before a service or resolver disappears, then retain and verify it away from the live environment.

An audit asks about a flow from years ago

An audit needs the path of data received years earlier. The service used at the time has since closed, and the system that resolved its keys has been replaced.

Fragments in today’s logs are not enough. The signatures, predecessor records, and verification state from the time need to remain available as one re-verifiable body of evidence.

Exporting evidence from a live system and verifying it offline after retirement

Where provin fits

Export the provenance records together with the credentials, controller, and key state they depend on. Verify the retained bundle without connecting to the original node.

What a verifier can check

  • Carry the material required for verification away from the live node.
  • Re-verify retained evidence without the original service.
  • Check the issuer, signature, and continuity represented by the retained snapshot.

Public E2E coverage

Public E2E: archiveverify and aggregatebundle confirm offline verification from retained records and snapshots; auditsurvival confirms restart durability.

How to read the evidence

Re-verification is bounded by the evidence and snapshot retained in the bundle.

Place verifiable evidence at the data handoff

provin puts receive, verify, process, sign, and emit in the same data flow. The architecture and specifications describe today’s interfaces and implementation boundary.
