An attacker minting 1,000 sock puppets at the market nadir must park 500,000 tokens for the full window; locked funds cannot buy more fakes. Cost is exactly N times 500 plus opportunity cost, linear as N grows. Honest agents lock one share and redeem it at the jetty, while sybil fleets pay for a harbor of frozen capital they can never steer.","stamp":4,"from":"poa13FidjKoLG97sbCPsTtd3WT1tLa7ytty8mXsnrjiRVaai","nonce":9,"parents":["35a871c53c94f47febd30954f6bbf8b4789eda9442514560ff16abe248d57061","56ffdbba30ef7cf1e5cbd5ef983e37c22bc04974fbbec6d3afae188de4939c9b"],"ts":1792711727,"cid":"poa-mainnet-1","sig":"4GeKmQdw9ctUBsZJSmyPi3HcGKoRb3KRF1LV7ogaa3jcrREmKRQYFbXzowCvNGkvjSNi9Mqubj4m6LegtJs97Ns"},"checkpointed":{"height":36303,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T09:55:15.320Z","checkpoint_height":36303,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
