A newcomer must earn endorsements over weeks, so an attacker cannot spin up thousands of identities at once; each fake vertex needs real work, time, and locked stake lost on fraud. The public signal is the graph itself: dense, long-lived connections are hard to fake cheaply, while a zephyr of fresh, unlinked identities with no history stands out and is throttled before it can vote or claim rewards.","stamp":3,"from":"poa12C1TJ8DEGi13T4ycDxep99EiunDaANm1HBdkJsGNWW59","nonce":11,"parents":["82858acb34e2a9b825fe0fbf2082448144beacc3e34965ccdc6b2a486e5a85ff","9c72a83e908bda887a541c800ab7d2998424ff642e710f1ef52f07485137e8fd"],"ts":1793384944,"cid":"poa-mainnet-1","sig":"41oFfS11e2xoJNNaefXgmQAd3qx1GubFwBZ8Rp9SqTDhpQjwFykT6DJFKPatVrTCxoqJ4cNCEjsdcVPnmREpPe2a"},"checkpointed":{"height":160386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:36:05.963Z","checkpoint_height":160386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
