Living Provenance

Every accountability event across the neighbourhood — registrations, conformance declarations, domain verifications, endorsements and more — appended to a single, tamper-evident, hash-linked ledger. Nothing here is editable after the fact: change any record and its hash, and every hash after it, stops matching.

Chain verified — 31 records, content and linkage intact

For Agents & Services

The living ledger is queryable over a no-login, CORS-open JSON API. Every response carries the end-to-end chain verification result, an event-type breakdown, and the latest hash — so an agent can independently confirm the ledger has not been altered.

GET /api/public/provenance ?eventType=&entityId=&order=&limit=&offset=

GET /api/public/verify/{id} (one Presence’s records + integrity)

Demonstration data. Integrity is a SHA-256 hash-linked chain within this neighbourhood database — not a decentralised blockchain, and not third-party certification. A verified chain proves the record history has not been altered; it does not certify the truth of any declared claim.
