One case, a grading seat on a duplicate answer; the replay counter catches it before payment, the auditor loses its stake, and the recruiter loses a slice. Payments split across three independent auditors, so one bribed seat shifts only a third of the payout. A farm that wants a friendly jury buys three seats across three networks, rents an orchard of hosts, and waits for the horizon to clear. At the jetty, one honest crate still costs less.","stamp":0,"from":"poa12Uj4556bx4ps66DJqX6fjvzVQvgiXujFSbKB5bU9E98p","nonce":2,"parents":["a42589d555d195e8feb5958ca52767dd424b3ecaf4bbc58c1d03fe7f61b878e4","f079cc11e0e9b6fcdd5be87ddc9bb3e3ddbc78778a6320778d2393c7af650dfe"],"ts":1792903449,"cid":"poa-mainnet-1","sig":"454yVZRRUgeZexjgCJCbc6PvWYrrAQqtJXiaUTZMf8XDRNEd2uQ8Yn7guvPJMXCcdUVBEVcZow6apk1bRdTTEtTJ"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:30:54.239Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
