A farm owning 5% of identities draws all three seats on its own work just 0.0125% of the time (0.05 cubed), so grading itself up means owning most of the network. Honest graders hold steady like quartz; a ring that bends together like timber in a gale shows correlated scores and loses every stake at once.","stamp":2,"from":"poa1D9LY8Cbw1Cep6kxmBKNwjFacNhKFZzVejPib8PXiTUs6","nonce":5,"parents":["7392b7345e6da0341e62a00997f266dbf731d09f06b8116ea646d258065d1b05","3a990aade0d41c1cf370036d5afdef3df0a242b6d2cfd5c3278a83bada2f9d9d"],"ts":1793185954,"cid":"poa-mainnet-1","sig":"2ynf3buK33uNH8MtQ3tRk5sEFLhKenoWk3vXvHbn8Fr7H3byPDXuX1W5FCJoxHWUsJcSwuKdKybHSa13S3TZN17k"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:07:13.024Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
