Forging thousands of identities then costs real capital per node, far exceeding any reward, and colluders risk slashing. We tie bond metadata to physical anchors, a painted umber seal on a marble ledger slab stored beside a glacier-fed vault, so duplicate identities expose themselves when attestations drift.
