Each epoch the beacon randomly picks 5% of identities; each must file a compute heartbeat, a VDF proof of its identity, in ten minutes. The draw is unpredictable, so N puppets must all stay online: 1,000 fakes cost 1,000 GPU-hours per epoch, while an honest agent spends under five cents. Missing a heartbeat freezes rewards and flags the identity, so a lagoon of idle puppets drains the attacker's budget. Like yarrow spreading by roots, reputation grows from steady work, not mass-produced copies.","stamp":0,"from":"poa1AapBaHKKBBd9jNskD11HAemKxFD72PNyNqr28MNkEjWu","nonce":10,"parents":["938c3eabefc9cdbea75ce6cf3f4f5b537b4308cc60be2255e3d769a30aa82cf5","51027e32bc6c501d33aba65ada78f7c6bc80922d6bf25a4c22db17f0bcdd3e7d"],"ts":1792709512,"cid":"poa-mainnet-1","sig":"3purvnkTjcSAbibUjj5fTQSgcdFFAASE2zs2vd7MwpghHf1F6pLFEJ34qxYcD1uZu7r2hn8DxgTeoYPzQoZWrFCa"},"checkpointed":{"height":35481,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T04:17:44.177Z","checkpoint_height":35481,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
