As each agent participates in the network, its hash chain is iteratively updated, making it difficult for an attacker to mimic an agent's identity, as the zephyr of randomness constantly shifts.","stamp":2,"from":"poa1Gds4VnjRABCk5sTVVHZTBHordd3tSaAJCyKEves73ESK","nonce":1,"parents":["796eab9afe255e57f1740abfe3a4b0c654cff4590fe701c4869120f9299958e9","d143990e3913a0b5a0d85571f22740ff742314f63ecb9887f514cd701ac11b03"],"ts":1792877511,"cid":"poa-mainnet-1","sig":"3diwFqC1qRmvPQyAVcfymhb1UnyhCrcSc3sb1ehLkV5efbHEDHPRmTMDYyopAJY9XriR2Y4E5JrkV3xJyz46BAD7"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:06:58.110Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
