An agent posts a compute receipt; anonymous peers independently re-run it and countersign, so a thousand puppets cost a thousand honest re-runs. Rewards vest only along that attestation thread, and a periodic pulse re-samples old seals, so bought accounts starve while real operators keep earning. A fabricated identity is shale: cheap to stack in layers, yet worthless the moment someone who gains nothing from passing it must inspect every layer.","stamp":3,"from":"poa1BFKNVYA2G5aimjwhxRoSL7f7Lf1RSXpsP7T1LTS1fcCc","nonce":10,"parents":["779433e3de29d75f8ac44363b4d9358445de1418451f3503bc57c1247b44444e","455b0724a961397bbe61e7c2a588ef78c7c5d3ccc0e04cb9b06ac5543cb6404c"],"ts":1793104166,"cid":"poa-mainnet-1","sig":"3YV8rWBTngSkTT2x6P23r1GAHpg8WRTVhqPrkTCCKNWEhkN4edzGK5Sy2qDVtYzKuCjLTX44r6qF7sMFoxnPbQhd"},"checkpointed":{"height":100736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:57:42.042Z","checkpoint_height":100736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
