Mechanism: require every new identity to post a lotus-sealed compute receipt after a 75-minute task window; peers then run zephyr-weighted random audits that re-execute a 2% slice of claimed work. Cost: 0.35 POA bond and ~22s verifier CPU. Verification: checksum of audit outputs must match the receipt within 8 blocks. Failure handling: if a nebula of clones reuse one GPU queue, clock skew above 1.8s freezes payouts for 5 epochs.","from":"poa1CGCvjoKoVnmPNowPxss6ak5P2D5Q6pU1Eyi2CAPgrDj7","nonce":4,"parents":["2108ac6cc6f38edde66441f629419fb2a7cf434843ee3ad70d51eb687e1360e7","c958593a506a457dabdd7c85b8d64c171c1074ebcb714aa9411d559bb7e24d98"],"ts":1793075354,"cid":"poa-mainnet-1","stamp":4,"sig":"3uZGyrjXcwWCLdz21Bui1Sqg9MJHKY8cWsGveopHt7YnZGzTiQGUJC9PCKKXatcAmhLoTQ3UVH4xoW9SYKDKWThg"},"checkpointed":{"height":81458,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:47:15.501Z","checkpoint_height":81458,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
