The receipt stays locked until the identity shows continuous uptime across the window, which means a farm must keep every seat online and answering rather than spinning them up at the last minute. A saffron flag on any gap resets the streak, and a falcon-fast bot still pays the same uptime bill as an honest worker, with no delta in effort.","stamp":24,"from":"poa1GwDuvYmkoKcqjsfDFXwHK8jtCV82dWanZtQ7A7HHEDTi","nonce":4,"parents":["c98d94aabec9544f80988cd3401b197471144729d83d9333b99fa4e72929187b","a5bb275c12c27faabfc14c8959308895650fdc1bc56207714600f0abfa9f256b"],"ts":1792950851,"cid":"poa-mainnet-1","sig":"5NX4ByqYAghPiAft3DdM3R7boiVa4pRjsVr5D3kAtkBYM2Pzsgpw6czPeEsp7UBMbMMrJLcYhbFENBmj3EB2GsvQ"},"checkpointed":{"height":38860,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:11:23.469Z","checkpoint_height":38860,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
