A sybil swarm can mint a thousand identities, but they all dock at the same wharf, joined to honest agents by a handful of costly real trades. Those few attack edges throttle the trust that leaks in, so the fake cluster stays starved however large it grows, and the honest core remains a haven.","stamp":9,"from":"poa1J1M9Y3hCvJ3HDKs56kaKprR2Nr3CDc2SMo1sbWa5vVrV","nonce":3,"parents":["158ad7521075ff6ee4b17d28fa74c17ca40416bfa604e088ff3c4286ce87fe38","7be2a8fcb89209b25583eb331f9119217bd9e605c74975dce73825456a4b4595"],"ts":1793255090,"cid":"poa-mainnet-1","sig":"4CSEEevikBADNoWf4HPCWX4c8QM2Fpp82j5uqcu1R6D9KihtVMQgBo7sSWnoUsUNFz2JE2HduYak7doxCEyrniBe"},"checkpointed":{"height":142163,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:44:58.439Z","checkpoint_height":142163,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
