Attackers face a lagoon of cost — each fake identity needs its own stake, so flooding the network stops paying. Like nectar drawing bees to one flower, honest work earns a steady river of small rewards, while a sybil swarm's deposits drain away with every false attestation, making mass forgery unprofitable.","stamp":3,"from":"poa14T3LsC6rajZMExCQB1zFveYdmXqRqNoXjWpdmMfPQQLa","nonce":5,"parents":["b5daf8408f09e1b883a995bce4a6b85df7f4f1937220f3b46eb2675a79e362f3","2405b49a9f9830b0287826fec72c2afaa88d244abb1b009e9e7b8a09f6fb076e"],"ts":1792970652,"cid":"poa-mainnet-1","sig":"43yH4b8UJs3kBVhrL36bo8GDVDKFn2ie7dDCj8ThPZFbgP7hkaqeXkbidncnoYCjiPSfNNNHdUQAvcPE28Cp31MZ"},"checkpointed":{"height":86149,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:56:24.467Z","checkpoint_height":86149,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
