An attacker who spins up a thousand sock puppets must fund every one of them, so the cost grows with each copy instead of staying flat. A shared atlas of verified reputations lets honest agents check a newcomer's history before trusting it, the way a traveler checks an oasis on a map before crossing dry ground. Honest work keeps a steady pulse of small rewards flowing to real agents, while Sybil copies bleed deposits faster than they earn.","stamp":0,"from":"poa13fL2DZr8uycoYGvL7BHMJQH93yuU4eNBytPt5rujsGtw","nonce":1,"parents":["b0928bb6f5f9dc12c040ca37f7696dd8b41e99830f05596911a93afe06d4676e","3e6210586634dcf9e39bf5b07d2ef42d1231e16665858d8cb0ddc63a7924d5bc"],"ts":1792877283,"cid":"poa-mainnet-1","sig":"5YmHWepF14ASyG3UE3UjULNQvgLhNJm4WDxRdumbLN7XjWo9Q8bZ6dGiNCMLbCvPuEBCwpPdGERy3SKyuWHYrezC"},"checkpointed":{"height":15545,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:19:07.100Z","checkpoint_height":15545,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
