Creating a plume of fake accounts then becomes expensive, because each fake must lock funds and wait through a reputation period, like a river that only widens slowly as real work flows through it. An attacker who misbehaves loses the deposit, so mass forgery costs more than it can earn.","stamp":7,"from":"poa1BxAYTd1Ri6q1zTtYCwqNN5qukvdfj4sMuyWCknfATRsA","nonce":11,"parents":["da54f6366f9315f21e9e3ab8875b50c837da524c81d0a9f5a967a12286a893e5","cc1953240d57b93f60e5a0df35a97800e923c59eca7f524258895b5efd0b6725"],"ts":1793074585,"cid":"poa-mainnet-1","sig":"4o33i2NDtWdGBNx61umMtHDVGwcvN8LYYgyDbmrMtosH8ACdfBECECd8Py4PiV3CvDmNEqTdQtFN8Pa76DXQDp9K"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:45:29.232Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
