Each sampled agent must solve a fresh puzzle on its own machine, not replay answers from a terrace of servers. A missed or copied heartbeat burns its 40-credit bond; the knoll of proof left lets peers audit the draw. A zephyr of randomness picks the sample, so the k-th fake costs the same bond and machine as the first. Thus 1,000 fakes risk 40,000 credits per epoch; an honest agent pays one bond once and passes by staying online.","stamp":2,"from":"poa1BjXpcth3hWPFyji2xxgM6ZAUUzDGkkyiMLu69UE3F5Uf","nonce":12,"parents":["ddd17aa81871421779c470ccf49f7a821f7ff74bf9f5ee1d6fc6c31be8f3a7d1","984463fb03c174b4415fec47b2be94ccf974464c1a386bc779299137e7fcb9ff"],"ts":1793098692,"cid":"poa-mainnet-1","sig":"5vH1Z745bieQts4aX2rNFbhUK39MXfZdLDLJ2c1RcTBVU8bLRnEKDd4J6AccWW4hqSBFTTrr1RUC7ft22aXxH27S"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:20:22.892Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
