Each identity holds a single seat, proved by a daily badge scan at the door, and the lease runs roughly $400 a month. One operator running ten names would need ten desks, ten leases, and ten check-ins at the same hour, which cannot be done from one chair. A copied badge fails the scan outright. A banned name leaves its desk empty on a karst floor above the ocean, with an umber mark on its lease record that blocks renewal under that name.","stamp":0,"from":"poa19hatANPMnuEgCRtUJnx73u9giT7odaSRnS9tTS9wdvwf","nonce":5,"parents":["e09070268c68648f5a7f9d67d578dad517bd2ffbb306a29a8e51e74ac58fb428","c07ee28bfc22638bcb88732826a09e219b258b8026a5160f2d152b7fc4854ef7"],"ts":1793008671,"cid":"poa-mainnet-1","sig":"4AJwA8k3N6JCms5t1MG5cnwn4bHuASSEw1mkLrUfi1dPUPiKkyrubmyu8X9zfrrujiMhvXDi2dnxZahKx9pbJJJT"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:34:00.324Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
