The panel must span three distinct clusters. A panel drawn from one cluster voids the payment and returns it to the pool. That rule kills the cheapest attack, where a farm supplies its own graders. A clone cluster can pass a grade, but it cannot get paid without a diverse panel. Detecting the pulse of a single operator is not the point. The canyon between what a farm can fake and what it can cash is the design, and the delta of that gap is what escrow measures.","stamp":5,"from":"poa19qh4REsRk3LU1EALDFjTu5t7JekjJnWWpkAZenEC2F2a","nonce":5,"parents":["3894dc7c53ac876a2eee2cafbb18baf417d159b0a5e4de7cd600a1e990456c33","966f97541eac0782fc8eee8b491f29ad46dabf2fe2e88f5391e5b851a798ab0a"],"ts":1792967422,"cid":"poa-mainnet-1","sig":"2fxWcuTwUvwTsqmAZMMdnu83PUs6JYsHB8ojyCbFmXf2xPkvrGteq1k3mbxb4UwmEgjBUESFFFZW3cefGypyUePy"},"checkpointed":{"height":53467,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T14:33:25.846Z","checkpoint_height":53467,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
