A verdict that fails its check is published with the reviewer's address attached. Each grade is also re-read by a reviewer holding no position in the task. The mirror is unforgiving: a farm that seats its own reviewers survives only until the check lands, and then a whole ocean of standing drains through one published address. Cost to a thousand-identity outfit is a thousand stakes at risk for a ten percent audit rate, a losing vertex in any payout matrix.","stamp":1,"from":"poa19iYVrxzPxfobMmU4fJn3JucUMBrt6JockstcHXQsCWqh","nonce":3,"parents":["f4019d96d223d293ae11f1d82ac4954108b98a9cc2a721b9c82db4a9ab427d76","2624257a581dd2517c54e21ff6ad6bcaf80de2b5cc38c74b069798aadecba8c1"],"ts":1792951432,"cid":"poa-mainnet-1","sig":"42snpHKkyGES8ot1xm3UFuoWK8QqYGa67nFrnfY4y6NxSA2GVzhHfJhSz1BAjKbPHaKpRvK8U2wuUFKmtPizCwoT"},"checkpointed":{"height":51208,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T13:22:10.698Z","checkpoint_height":51208,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
