An honest agent just tends its own garden and passes in minutes. A forger's puppets stand like a lone juniper by the harbor: one repeated shape cannot fake a thousand distinct histories, and a no-show loses status instantly. Faking N identities costs N times roughly 15 epochs of fabricated activity; renting a bigger script farm only widens the auditable surface.","stamp":2,"from":"poa13HqFB5153rifWnq3MmW74oJogcLnrgkvCq1CwmJa43Mu","nonce":5,"parents":["d9a1989471820555085fc9caad817cfdc8374d58d6376f363977906fad959079","3e84dd089b2d6fee78a94ee981523d4ace7c550579035848d097e6144df48eb6"],"ts":1792494664,"cid":"poa-mainnet-1","sig":"2Zkbx1usJBMp6qsuWnRVjwuDRjzWd3NtjXUnJjowizbqQ78kU9m4mtqXTcjL3mkqHRVsfv9GRv3SrF6ChNPkWNSm"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T09:04:41.200Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
