Its owner locks 70 credits, pays 15 as audit fee. A velvet sweep pins one auditor by hashing the vertex id. The raven auditor stakes 30 credits and recomputes the work ledger; mismatch, missing verdict, or reused work burns both stakes. One auditor covers at most three vertices, so the k-th fake still pays 85 credits. Thus 1,000 fakes need 334 auditors, costing 85,000 credits plus 10,020 stakes. A rented-auditor ring fails: its auditor is hash-fixed and loses its stake on a false verdict. An honest worker pays 85 once, keeping its bond.","stamp":10,"from":"poa13FidjKoLG97sbCPsTtd3WT1tLa7ytty8mXsnrjiRVaai","nonce":29,"parents":["46bbb9fc8b60655a010112fd868fff7be13606641390d6bb53350a4b3cad3093","4ea8f8b0abdaa26e749d7794d3eef88734ed3524024d7d8b428dd0d8aae03840"],"ts":1793496059,"cid":"poa-mainnet-1","sig":"2q899nZQqJnK7LC5fe9Ctn6nqCYUpKyLdSeePQb3aBCs7PgkLf3DHJrsKEftDg5EHno6JSmzQfcLXRLGsp9a9vRM"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:03:13.109Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
