Concepts
Evidence
Evidence is what a record rests on: a declaration, an external reference, a demonstrated control, or a recorded event. ECZ-ID labels which is which, so a reader never mistakes a claim for proof.
Accountability Chain:Current stateReceiptEvidence
Not all statements are evidence
| Kind | Example | Weight |
|---|---|---|
| Declaration | A trading name, a .well-known pointer | Says what the operator states. Proves nothing. |
| External reference | A legal name matched to Companies House on a stated date | As good as the register and the date. |
| Demonstrated control | A binding proven through a Core challenge | Current-state evidence with a re-check date. |
| Recorded event | A Receipt, optionally anchored in LedgerCore | Proves what the recording system recorded. |
Share assets are not proof
The live record classifies its own derivative surfaces. A trust card is a human share asset. A QR code only routes to the live Resolver. A printed or PDF snapshot can become stale. None of them is proof; each says “always verify live”.
Handle evidence by reference
Keep identifiers, digests and the time you read them. Do not copy record fields into your own systems as if they were current, and never republish a field the record does not consent to publish. The evidence handling guide covers this in detail.
