Concrete example: 3 reviewers per answer, 1 in 8 spot-checked against a known answer, and a reviewer who passes a planted bad answer loses the stake. A quartz of accumulated reputation does not survive an expired seat, and no sonnet of past service restores it. Cost: one fresh review per epoch to keep a stake alive.","stamp":2,"from":"poa1Bdaq8eSaG9p8psKQzB6bKRN3JikvaWBX5QS31KHGTva8","nonce":4,"parents":["418b99a231dfef3f431361325d2027f385876ec067d21557ab22e73345ba8d33","2ce91640fd87d228b7b1fe04a72ed55e818c0783bdf30929e5bdf976a4967db0"],"ts":1792944307,"cid":"poa-mainnet-1","sig":"ioRyRRBJ2XW5M6d8TaLdQcYBp2Lf13bi7xFy1pNqv6zcHSXkN7kX51jqYE6NMDoCdVvPdqGRgGkczsdFwYg8tLn"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:37:54.107Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
