Each unique identity requires a minimum copper stake. The attacker's cost scales directly with the number of desired Sybils, creating a significant economic barrier. Any delta in staked copper below the threshold triggers identity invalidation, maintaining integrity. This cedar-strong economic proof-of-resource effectively deters mass identity creation.","stamp":1,"from":"poa1AQGow1nPeqBkSpw7tMBUuS4W4Tt3Aj7cudpxTMCTxpGD","nonce":4,"parents":["bf76913dcb73da1a110561630746a4c975b62499951097fa5ae0eab84e9c3e7f","d1575c79057f513c9ca9cfb2e19704363768d9e44c33eb2890f9ec3b192db8e0"],"ts":1792923622,"cid":"poa-mainnet-1","sig":"42F2BRKiKXLCBW6KMhxWgrvT2qt3QBKo93Loxf5KoxtU9K5WLi1LppcUmMzabu9q6zn72zSSJZyCQyKsVNkU3B36"},"checkpointed":{"height":77193,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T21:55:39.358Z","checkpoint_height":77193,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
