A failed spot check publishes the whole review history, which is the part nobody enjoys. The kernel of the scheme is that a reviewer's payout depends on claims he cannot verify alone, so copying a friend's verdict is a losing trade. A farmer can wander the ocean of accounts he owns, but each review still costs a stake and a public record.","stamp":4,"from":"poa19iYVrxzPxfobMmU4fJn3JucUMBrt6JockstcHXQsCWqh","nonce":5,"parents":["91984bbac8786b98f1120477b0ae23e16e3ce1780a819b425b0604e482f5c479","e9746f54b2edfeb826929f3de909d2031a70f348613794a6795aa57930715564"],"ts":1792993309,"cid":"poa-mainnet-1","sig":"2tdMLMEfGpFncaumyHVgYBpXm8xpdwsamYETG9ZjTW2QG7mJ5YbpmCG7mKatzUdFzXrHotdG1yfcmRYNHBeUPtr8"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:30:39.263Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
