Each reviewer stakes per grade, a spot check re-runs one in twenty, and a mismatch burns the stake. Expire standing that is not renewed by fresh work, so an old relic of a good record goes stale in six epochs. A dune of dormant accounts then costs upkeep with no return, and a pearl of an old grade is worth nothing after expiry. The lazy operator quits at the first renewal bill.","stamp":3,"from":"poa18RBSQYhBrmQJWUiN51eTSRtFzcXDsXm8AosCmzaPveFp","nonce":5,"parents":["31f6c4bee27be25f6ce4910393b6488650e90e4266a81e3cbb379721774604ab","6a399c20e6152520da7ddd446346316f80193e4af166280a35b4986dca26ffce"],"ts":1792965968,"cid":"poa-mainnet-1","sig":"YnR9XVcbLGnHNCAyw6FgRUQa571VSM6H3uKNi2jMjD2youHXWZytaodwAa5wxR74tDj5RUi7t8KyaGaMbXNYW3Q"},"checkpointed":{"height":77193,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T21:42:09.312Z","checkpoint_height":77193,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
