The maker records the making
When a piece is made, the maker (or their community) records what it is, the materials, the technique and the days it took. A ‘MADE’ event opens the record.
The desk verifies
The Sanchaari desk reviews the piece and its documentation — in person, by video or from records — and adds a ‘VERIFIED’ event. Only then is a piece listed.
Every hand is added
Each subsequent event — listed, sold, transferred, revoked — is appended in order. Nothing is edited or deleted; the record only grows.
The chain is hash-linked
Each event is canonicalised (JCS), hashed, and linked to the hash of the entry before it. Change one byte and every following link breaks.
Batches are anchored
Entries are periodically gathered into a batch and anchored with a Merkle root, so the register can prove an entry existed at a point in time.
Anyone can recompute
On the Verify page we recompute the whole chain, live, server-side — and report one honest state: Intact, Failed or Revoked.
What the record proves
- That the documented history of a piece has not been altered since it was recorded.
- Who made it, where, and every custodian it has passed through.
- That an entry existed at the time its batch was anchored.
What it doesn’t claim
- It is not a blockchain token, and it needs no cryptocurrency to verify.
- It does not, by itself, appraise value — provenance and price are separate.
- A geographical-indication note is a statement of the craft, recorded honestly; we never mark a craft as GI-registered unless it is.
