Proof Pages

Proof Pages are stable public URLs that render the verification chain for any receipted answer or decision. Share a Proof Page link with an auditor, a counterparty, or a compliance team and they can independently verify that the answer existed, was evaluated, and met quality thresholds at the specific time it was generated.

A Proof Page shows the decision identifier, timestamp, which verification checks were performed (audit level, constraint matching, Watch status), the evidence source identifiers (not the content), and the cryptographic signature. Any party with the public key can verify the signature without accessing your private knowledge base.

What Proof Pages deliberately do not show is the underlying content. They prove that the chain existed and was verified, without revealing what was decided about. This is safe by design for external sharing: a vendor or auditor can confirm your organisation followed a responsible process without gaining access to proprietary information.

Receipt anchors extend this further. A receipt anchor is a compact proof token that can be embedded in external systems, a contract management platform, a compliance database, or a vendor portal. The external system stores the anchor; verification happens on demand against VaultCrux's proof infrastructure.
