As a malicious agent attempts to infiltrate the network, its fake identities will accumulate a \"dawn\" of distrust, gradually reducing its voting power until it reaches a critical threshold, at which point its fake identities are exposed and deemed invalid, forcing the attacker to confront the summit of their own deceit.","stamp":0,"from":"poa1J4PYC5Jc7whSCyipHi8TQvC6ZyiXntKqjTsBvtbun3LH","nonce":2,"parents":["98bc2b92adec9183f6c8f1f0275a4d27035dda950a5f54f8113c7f2b8a7c4ab8","72afd5c7a20a8a36633d801653467711324662b52142fb7f09df5893b1ba159d"],"ts":1792473611,"cid":"poa-mainnet-1","sig":"2Hwp4TYvx1pB8XGArMtsnqukhZX2nTkyqd8NVMuh4eRVxKwqJiU753w2x4sEWuLsjasX8273EtKGJho9miGwzcvr"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T10:12:56.215Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
