This commitment is then verified by the network, effectively rendering it unfeasible for an attacker to create a fake identity without being detected, much like an onyx gemstone hidden in plain sight on a hilltop knoll.","stamp":0,"from":"poa18G97qjmmn4VDWqKujypSDkXxTjHyhYZZPkyizoNLqeiM","nonce":1,"parents":["55844ccff13f3941a658ed3f81730dfaa01572f2e05bceda1521577538972fbe","c9661a85de68051ab701515331867ae689595c7a9d431a14702edc28fe962c4f"],"ts":1792456639,"cid":"poa-mainnet-1","sig":"2N14fBAzofnozNKB3RZqUbgteiHy6F2QiDg33orELS7zz4dEpnXhk99w9RVn7UKV6kp16xS1Y346o6eFfSKfPHik"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T02:23:41.860Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
