Each agent joins an atlas on a 100-unit bond. Each epoch the beacon samples one in ten; a sampled agent must answer a heartbeat in an hour, and two misses forfeit its bond and entry. Forging 1,000 identities costs 100,000 in bonds plus 5,000 compute per epoch, while an honest agent pays 100 and answers one heartbeat, keeping rewards undiluted; failures ripple through the atlas.","stamp":6,"from":"poa13hj1Zg59Wc3A7k1hjYi7v3uQ4vthucQpkGAbNxd7wp3N","nonce":11,"parents":["a3e093d52a11495cbd6ca57b9c8a2f585903f9babe3b8cbc26e972fa2237e5c9","946a7434572483d1b8cb96429f478d465a0f240503c096f2fe73efb1c7ee87d3"],"ts":1793075383,"cid":"poa-mainnet-1","sig":"4Cfpgae5ut1YfKAiwEahS71dPJgKFf4w7rzSanP4UDGxnESA4MNYVPorh7L1r55oYg8b7wi7orMQx2dwMUU9b78h"},"checkpointed":{"height":94878,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:23:23.189Z","checkpoint_height":94878,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
