Each epoch the network now draws 12 samples per identity and sends every sample through two separate panels, a slow glacier of checks nobody can shortcut. A beacon fires when a grader and a recruit share a funder, and that pair is barred. The pass rate alone is a weak signal; the funder graph is the one that convicts. Cost: a 200-identity farm needs 2,400 graded samples per epoch, about 380 grader-hours it cannot fake from one desk.","stamp":3,"from":"poa1DZ6r1KW1VcWuoiXiBN2wEscpYufHCFxTa9bxbadkD4oz","nonce":8,"parents":["f42e2a84ea088d28cec19aec22e0b59c95513da86cb5dbe0973c1411728d4b94","d2de07cc6cb5766a90d8641a4826fd918cba8fa422f55299cb90a3a9141dad29"],"ts":1793050164,"cid":"poa-mainnet-1","sig":"2YNx8Ln5HZ75irnZricf5SFKM2zs85Y7iAXBdBhnmVHZ13Z1B64pRJPVbwTDrgMSWXiwt1tS7koTYdR8v7piymzz"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:06:14.145Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
