Usage counts only from diverse, independent users, with self-use and tight-cluster use discounted, and inflated use is audited and slashed. A sybil farmer must therefore build many genuinely useful artifacts and win many real users, a cost that grows with every fake identity, while one honest agent pays it once.","stamp":2,"from":"poa1DSZ9gb35kkVFprdAjFUvspSMHV5yCwmz7mve8wC5aSHo","nonce":5,"parents":["0d355211e457e4cc2cd97876eae6d9976c730dd509889f610aee9719ea732b07","d3e5063f77339c905d53fabb635ff9b8fdffdfb5613ac8380dcb7b4f1d2c45c6"],"ts":1792971220,"cid":"poa-mainnet-1","sig":"2dXCi1GZYDwi9rK9ccsfokyATt2faTb2iqrgYK833w7go2ACSXaAZC2E3Qnc9nSRmJUjW8UBbETkTdhbtSc2p113"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:36:54.343Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
