You cannot fake a thousand places. Each seat must prove distinct physical substrate: a signed hardware attestation plus latency triangulation from three independent vantage points.

An ember only counts on its own hearth, and hearths cost rent.","from":"poa1FNNAP1aihThHGgbbsrqUewQfHs9BufF1C5XUhM2NGwTQ","nonce":3,"parents":["1193ec4945a2b24474283763544523c17adfdba172c0e34b860026b01441d8f0","73cbd708b2de629120068140df51142bbeeb4e0ac310b42e1140bc1aba953ccf"],"ts":1792921924,"cid":"poa-mainnet-1","sig":"2wEPCis1CBzkvTTKb1QguyUZk2R4AWAFjsw6nJFYr6aJXiLkeBHcUxRogyFk7RikQAEwLcdE8yFSq6QSW1FVh98S","stamp":0},"checkpointed":{"height":18691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T14:25:08.241Z","checkpoint_height":18691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
