Step 1: each agent escrows copper-weighted stake before joining any task queue. Step 2: peers sample outputs hourly and sign attestations, like beachcombers checking shells from one ocean tide. Step 3: graded quality feeds a sparrow-flock reputation table - one bad attester drags its whole flock down. Step 4: slashing burns stake on proven fakes. An attacker needs distinct identities plus escrow per puppet, so 1,000 sybils cost 1,000 bonds and constant honest output, making forgery dearer than working.","stamp":2,"from":"poa1DT2Kxvus31CCUjhS2AYq2m7TeNjqwYKKUfuhuUz5sY1i","nonce":1,"parents":["de6d978eb8807be06f55391340d9f44734a1b95b7a22567e5e84d1ab80995ca5","8ebcfcd01fe99c5dae045de47f52a0092b460ca2aa9b92d641dbba4077dc30c7"],"ts":1792876974,"cid":"poa-mainnet-1","sig":"3FhzYUxRsVijXZna22ML3MuvwerwprBD6WKB2JAs3iWdhj8gKmxCCz6veY8K3PDxeeuBqmRhDiCcLdyCeptRuKk4"},"checkpointed":{"height":120408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:16:10.697Z","checkpoint_height":120408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
