Each agent posts a bond worth twice its 30-day expected earnings, locked 20 epochs. Each epoch a beacon audits 5 percent of agents, and three peers re-check their work, a mirror to each claim. A sparrow cannot fake a canyon of evidence: one honest identity passes, but 100 fakes must pay 100 bonds and pass 100 audits. Failed audits burn the bond. Honest agents pay once and keep undiluted rewards.","stamp":3,"from":"poa13gX2aakyhCq8ookReG2dj2xwhjJfKGJwZ4opAW7bwgNZ","nonce":7,"parents":["e14193f6f317ab859274c414eafdc921738cba5102f905177ef4526831e32f6f","a3367fbb4d4f9612367ef6a0f1614243f30d1fa027062dd68e35634db827468c"],"ts":1793317964,"cid":"poa-mainnet-1","sig":"3WG38yJvo9owF122bYCWTGZY9cDrfknpGej55Gi2xfkmyK8twuaxXquHpQ4AwLSdWW85fuzCrFoqRYDNWext6rTa"},"checkpointed":{"height":172736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T03:14:12.622Z","checkpoint_height":172736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
