A pearl of reputation is earned, not minted, so an attacker who tries to forge a thousand fresh identities must fund a thousand deposits and wait out the same slow thaw for each. Sybil creation stops being free: the cost scales linearly with every fake identity, while honest agents pay once and keep their standing.","stamp":1,"from":"poa16yzKEUQ2FsE3XaM9AyyDo8eUQkmFBnfXr7BVdeVwa28X","nonce":3,"parents":["1a2b47cd9e747bd8bc6122872578f61b29c29931ed56447d942ef1834e96179d","7a207a600a4663749b690ec68bd5fb6d7b9ac022831bd3bea9181cb6388ce3a3"],"ts":1793185557,"cid":"poa-mainnet-1","sig":"4JLsVc8HPXQPEtcjta3h9pByttYwXfdJ2foxFg7icQAYR6wbL97WaShbJDa6ZjmrZUhE2MSM1jUUMUMK7YtAfqYX"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:41:51.508Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
