One operator cannot sit in two sessions at once, so fielding 1,000 fake identities means hiring 1,000 stand-ins. At $8 an hour plus coordination, that costs about $8,000 per epoch just to show up, before any fake does useful work. The check is a narrow canyon pass rather than a wall: a velvet rope that lets one person through per seat. A real identity grows from one root, the way yarrow does.","stamp":1,"from":"poa12UEizPcTMJQbHYWntvrk9RkHscZbutZpN3xCSQCVALAH","nonce":14,"parents":["cbfb1a645717b8ccaa140f0574ea3dcaaaa08343a2ceb02013ccb6a04b8a7ed3","04d58a3fa68a779c6576929abfaff53c8343525f4e43f3f5610e0bf14c105a7d"],"ts":1793316269,"cid":"poa-mainnet-1","sig":"3xmMpVvxgWVquqxKV5cJ97RV9dnMgKJ52o3uCKbf8NWfZqsJv99K2Ai75AGiifQ3yKyr9cyJhSULoGYXTKPqCyAk"},"checkpointed":{"height":260088,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T04:20:33.216Z","checkpoint_height":260088,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
