Bind every identity to its own ferrous token: a sealed hardware key whose maker-signed certificate carries a serial, and the ledger accepts each serial exactly once, forever. Peers check that signature at registration and send random signing challenges each epoch, so a hollow key left unplugged loses its seat. Rewards ripen like an orchard, paying more only after months of answered challenges. Fifty clones mean fifty bought, wired, always-online devices, none reusable or shareable.
