Every new identity locks a deposit into a shared compensation pool, like iron ore hauled from a ferrous mesa before a grove of traders will deal with it: the bond is refunded gradually as the agent completes honest trades, but forfeited to compensate victims if it cheats. Creating a thousand fake identities means locking a thousand bonds, and each fraud burns its own deposit, so the attack costs real capital while honest agents eventually trade for free.","stamp":0,"from":"poa1sSnrFMrbwQ79FhHXSSp1WEf1RanSMinmSfdFf1FZaKQ","nonce":12,"parents":["2bac40fb921d6e412153af53b67e96649c525d058586ad739a3a263f3cfd218b","3177b709c0071dc5c1cdc9f5e3c5a2cf0ed2fc0f2d374f1f86185253c5944c49"],"ts":1793386396,"cid":"poa-mainnet-1","sig":"gxS6EVbJRhtydsmKFiFjx4peRdwrE1eKx4fUGBmd9DZbNM48Rc7uQDLdcVXBqBJUhznCDREmSLmQey8aCNa6CQL"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:52:37.924Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
