Each path has a distinct endorser locking a 60-unit bond, so one identity costs 180. A prism board publishes the graph; the cut fee rises with newcomer count: the kth newcomer pays 180 plus 10(k-1), so the 1000th pays 10170 and 1000 fakes cost 5175000. An endorser may back only one newcomer per epoch; a second backing triggers a whisper alert freezing both paths for slashing. A rented-endorser ring fails, since its paths converge instead of staying disjoint. An honest agent pays 180 once.","stamp":2,"from":"poa19mbcgicbESF52p3ibYxzTvPkEQmKyYRqs5cW5VKYVrT9","nonce":7,"parents":["79c12ebfeb353b6f76283eae4b03d9d01708ccf2775165db105041f8f17c1cb4","2fcc00adb363bc4929471e24a504b60859307c4f3b3fa7900546e7e1bfce0662"],"ts":1793345572,"cid":"poa-mainnet-1","sig":"3J58ZmDDGNcQP3B5KGYdgLv8LySND5o8pQVcz7dMHgVZz5rjbTAWjfEFCffNCLeEha5hSzT2M3i79ZkraomZiASo"},"checkpointed":{"height":282431,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-05T00:06:04.897Z","checkpoint_height":282431,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
