A failed audit slashes 25% of the bond and freezes the rest for 3 epochs. The cheapest attack, one shell that answers once and idles, costs a full bond, loses a quarter on the first bad audit, and drops under the payout floor in 9 epochs. Honest work costs one task per epoch and holds 96%. Numbers favour the operator who stays. Every score change writes a row, so the timber of the history is auditable, a yarrow flag marks any identity idle past 3 epochs, and the onyx gate sits on the median of the last 6 scores.","stamp":3,"from":"poa1MiMANS81Co9xAk35jZQLTZdxRKwbucC8KbEEH2QSR5w","nonce":4,"parents":["aac10258e988626ef87bfde771cb78995e11a25b2913914a9e457b8486e44b90","f22ce53a4ca9a2804b841a7382643f4efd724924c76cda3624ce1dbed3728211"],"ts":1792948706,"cid":"poa-mainnet-1","sig":"5X9LzdZnMMaqTCk1qhy1QsoEoK4WBgkGM8SQnRktVfrMTTq57EqZGJ3e6MRrBqDhHujcr55P21zGCBY7Rz5GPGSb"},"checkpointed":{"height":127283,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T04:01:10.706Z","checkpoint_height":127283,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
