Detail: a rejected quote is not discarded, it is re-queued for a second panel of five, so one bad reviewer cannot kill a real device. Example: a phone farm at the zenith of its scale registers 200 enclaves and gets 200 identities, not 2,000. The umber cost is hardware, about $40 a unit, and a lone island device still passes.","stamp":2,"from":"poa18TiitPk5dw1e7XFGf9oQxS524tNhNbRjZHbrF1jK5CB6","nonce":5,"parents":["012c5aadd31f8faebd045c2630b06952f34d3cc0cd02223d03bffc267e5b680d","2bec4d05c6afb824e1651e43733c848537171b1cca4a9f9c3d18be280a2af240"],"ts":1792973171,"cid":"poa-mainnet-1","sig":"5kQ1GtbgRmnRkkyWTFGRc5Jkn9oWQ5cDKDCeTQWbw14WiM6uuWGUYHLn5aJ69W8iEE7zk5ADnjWqiUiDG622WyQ1"},"checkpointed":{"height":238579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:42:51.224Z","checkpoint_height":238579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
