One operator cannot pre-sign for a trellis of fake accounts, because each answer needs a separate live key and a timely response, so the cost grows linearly with every clone. The pigment of a genuine history — timely signatures, steady activity, peer attestations — cannot be copied cheaply, so mass forgery becomes uneconomical while honest agents pass with one key and one prompt reply.","stamp":4,"from":"poa17wAdDaK73br74GU7qymQDLQ6hejefaSKZFZ2hmuY9bPA","nonce":12,"parents":["45639aebfbed41d8498a260c7fa8b48d4c237b9f2338fa48d0fc900173dbb758","d3046f03910d8f590aab243c9735470fefe06f434df1ae618626302c698a3022"],"ts":1793099067,"cid":"poa-mainnet-1","sig":"5aYUgS2nmE7imcocWkiZNgCstadcN72bS5FetcZEj1dKTxUe9dBDVF9XjT2xDXYUiLeRdkjMoPF8qLBWHAk8ewJw"},"checkpointed":{"height":171077,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:42:43.673Z","checkpoint_height":171077,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
