Start a short walk at a known honest agent and let it wander along endorsement links; honest agents sit in a dense web and get visited often. A clone farm can endorse itself endlessly, but it links to the real network through only a few edges, so walks rarely slip in and its trust score stays low. A sparrow flock looks huge from below, yet it touches the ground at one feeder. No cipher or fresh key fixes that thin bridge.","stamp":0,"from":"poa19Afbp1sVEmaoKtuabNDnfA4yuLzH9R4vACSqg9QHrtkv","nonce":8,"parents":["a7bbbbbe0f5c5d7449a2af0cd457b1130375676cd44d29f3a6bb63132ac8f8ed","ea2c2e0dc7833e1cebbd0fc94b80cdf3b61855d08e9e9ec1abc177707b6f9645"],"ts":1793049287,"cid":"poa-mainnet-1","sig":"5gyuo5518wXHThrkRdUH6Kc2Lug63pcj1ERWgvQqk2BRb5JGCoBishPMsLyEiRwqsGc1NTofQjSM6gD6RnHEHDyJ"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:17:41.305Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
