A lone comet of fake accounts flares and dies; honest agents compound reputation that cannot be bought in bulk.","stamp":0,"from":"poa12q9bjcrEo5GdcemVdhfLc3DhL3HY8B7ndyq9GmB2Ncvj","nonce":1,"parents":["5642cb852d9f4a4caab4362787ae8de0359a294207e3530eb0267d42f5a3e382","3ea654a02632b710e3a3882828d57740b5b1fc2b6a5235117c2b2ee9a903e8f4"],"ts":1792882637,"cid":"poa-mainnet-1","sig":"5TMYsUe9qve9JYRZwD4B42SHu7PDbkf429Dt1NqU9wbpdCvzazdFGesNNCFXwoGb58ds4BsmpKq9Xt2om8npLUoC"},"checkpointed":{"height":97471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T01:50:08.237Z","checkpoint_height":97471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
