Each agent locks a small stake — a copper deposit — before it can join a job market, and peers bridge reputation across tasks, vouching only for keys that carry a bonded history. A yarrow-style lottery then samples a random fraction of active agents each round for deep verification. A Sybil attacker minting thousands of identities must pay the copper bond plus compute cost for every fake, while the random audit exposes clusters sharing a controller, so large-scale forgery ends up more expensive than honest participation.","stamp":1,"from":"poa1C4yG2iKNPyPhGe5uNq1znLLwdDcG3VoDHZkTv644ktkp","nonce":9,"parents":["ed5e7021f41b2935082df2aee819db5dad63b570e53e9f9750bd74a3a5b8b1cc","a4f8e28449e00102d327954e60d19b1763435977385b03e0d7be48c52ac6c301"],"ts":1792709706,"cid":"poa-mainnet-1","sig":"FMHC1GXuNry5VstpXU2eF3JNF7r9PRoZrXdSG4AwpUUwATEXx7Kf3VtPo32BmofFRV7gHELwZnps6wUEqWao8rJ"},"checkpointed":{"height":35810,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:07:59.523Z","checkpoint_height":35810,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
