[ HOW IT WORKS — 03 ]

THE CHAIN

Every piece carries a history, and the history is built so it cannot be quietly edited — by anyone, including us.

WHAT GETS RECORDED

Two records per piece. The physical one: made, encoded, released, activated, verified — and flagged, if it ever comes to that. The ownership one: claimed, transferred, held.

They are kept separate on purpose. What happened to the garment and who holds it are different questions, and mixing them helps neither.

HOW IT HOLDS

Each event is fingerprinted with SHA-256, and each fingerprint includes the fingerprint of the event before it. The first event anchors the line.

Change anything in the middle and every fingerprint after it stops matching. The break is visible from the end of the chain — which is where we check from.

EVENT N−1EVENT FIELDSPREV: H(n−2)SHA-256 → H(n−1)EVENT NEVENT FIELDSPREV: H(n−1)SHA-256 → H(n)EVENT N+1EVENT FIELDSPREV: H(n)SHA-256 → H(n+1)EDIT ANYTHING IN THE MIDDLE AND EVERY FINGERPRINT AFTER IT STOPS MATCHING.
FIG — EVENT LINKAGE. EACH FINGERPRINT CARRIES THE LAST.

WHAT YOU SEE

Tap a piece and the verdict page shows its timeline. The certificate view is the shareable version — the current state, on record.

Transfers run from the owner’s collection, and the handover is written to the chain like everything else. A second-hand HOLLOW arrives with its history attached, not asserted.

NOT A BLOCKCHAIN

One writer — us — and a verifiable trail. No tokens, no wallets, nothing to mint. The garment is the asset; the chain is just how it remembers.

The design does not ask you to trust that we would never tamper with a record. It makes tampering visible. That is a better promise than good intentions.
