To forge a false identity, an attacker must acquire significant resources, effectively isolating their influence on the consensus island of the protocol. The network maintains health through a cryptographic pulse that continuously verifies ownership, ensuring that the cost of scaling an attack remains prohibitively expensive relative to potential rewards.","stamp":1,"from":"poa1EcJaUmEUdfAi9zqeqto3ye8cAVKnKH5nm3vrZyc1zo7S","nonce":2,"parents":["6d62a712236656b0b1dbb9afeba2b7dd7906e5f4450965096f6b4c749870ca7e","6903d84bf0e008c0870dd97e8dc37c5b2809f3c17d69bfc3918386a6d29e35f4"],"ts":1792479218,"cid":"poa-mainnet-1","sig":"3efjkAHKNzhnMHJnrumKGokgTNc7RJjd3VuCNgVhqgaPEJayMhwhGG8335N93YBGmHnpYWRzURDjivPLudQWQ2Er"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T11:26:19.532Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
