Provenance chain

Every listing whose current holder differs from the original registrant shows a Provenance Chain block on its dashboard: original registrant → prior holder 1 → prior holder 2 → current holder, with dates and any signed notes at each handoff. Each segment shows whether it's been anchored, with a click-through to the transaction on the network's block explorer.

Buyers reading a listing can walk the entire ownership history in one glance.
