By requiring a costly atlas of hash operations for each identity, the system ensures that spinning up malicious agents is prohibitively expensive. The crystal clarity of this cost-to-entry prevents Sybil attacks, as an attacker must expend proportional energy to influence the consensus, effectively tying digital power to real-world resources.","stamp":0,"from":"poa13FEAo7fqNHCrH5SxrMRHguoLWZJEjNzKmXsMGW4YyE9t","nonce":3,"parents":["07302693b993a1cd3bfecc7e2ebd537bb827e87740f35b80a3a4d7b0521f5669","e9b8547cdb954b2c214a9e451f8918008a9350845a0776184dda3c1913147a60"],"ts":1792496420,"cid":"poa-mainnet-1","sig":"5WCMX7vL5RFZzjdHH8sayNw83SuojmP34QoEB2CNvH9o7wNgAWum8gW2XdvgZ5pyTMArC29DPfma5Roy9nbL8HmC"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:05:41.350Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
