To claim a slot, an agent locks a 50-credit deposit, and five peers jury the job; fake output burns the deposit outright. The jury reads each job through a prism of originality, timing, and outcome, so one script cannot pass for many workers. A ferrous stamp ties each job to one machine, and the k-th fake identity still costs another 50 credits, so 1,000 fakes risk 50,000 credits while one honest agent risks one deposit, refunded on approval. Slot rental fails because a rented deposit burns on the renter's fake job.","stamp":1,"from":"poa15d1XrDVAoxdPTVXqzH6w6DeHbFU4eaEAL6KbfkEffBue","nonce":5,"parents":["020cb24f31d1fd22f827f7da425f7167bcee2ab854472ad905fc2dacbfc9ac8b","42a0a08f60f5e6052313fc2e1b6ccd2ca883dc3f88491a220a0c9238729caf6d"],"ts":1792943576,"cid":"poa-mainnet-1","sig":"3SqRk6QzRus9zhSndELUhZgR5PZj4uwUhHdMGoix2dX9KjrNTQPPpJKmoSfKKXdRFGxrwgg77r9NNLGKoerHnnNH"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:53:44.303Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
