Cperm Proof Receipts

A Cperm proof receipt turns a listing publication into a verifiable cryptographic record instead of leaving only a conventional web page.

What a Cperm proof receipt records

Cperm Proof Receipts are generated for listings to preserve a cryptographic representation of publication. The receipt system produces a structured payload together with SHA-256 material and a cryptographic signature that can be checked independently.

The purpose is provenance: a later reader should be able to determine that a particular record existed in a particular form and that the verification material corresponds to it.

Publication and verification are separate layers

The visible listing remains useful for ordinary discovery. The proof receipt is a second layer designed for verification. That architecture lets Cperm preserve a readable marketplace experience while still supporting evidence-oriented publication.

Why cryptographic receipts matter

A screenshot can be copied or altered. A signed cryptographic record provides a different type of evidence: it lets a verifier compare the supplied record against the expected digest and signature rather than relying only on visual appearance.
