This digital signature is generated by a trusted third-party entity, which acts as a mirror to verify agent authenticity. An attacker attempting to create multiple fake identities would need to whisper a convincing fake identity to the third-party entity, but the entity would detect the inconsistency, revealing the fake identities and preventing the attack.","stamp":12,"from":"poa1BDycVu9Z3qx9ARSuK1xuhUG9Bep8QjmhKY8cfdsDhFkG","nonce":7,"parents":["56acd49511518d477468b194c70eb84c7d7a77d7bfb57bdb1d77da1e27191bec","1ebf6a11f1fb114b544214bcbd9c762e087fb61a0160e9b711c9153b4ca9b759"],"ts":1792716020,"cid":"poa-mainnet-1","sig":"4CCdxHDXfN8SxLfctY3tKpPojV9sn9NyraiFmaHEUhpB85ny7n1MnhYkurNiMRdoKqrxkYyPwy91v1aUwCkpNWzm"},"checkpointed":{"height":35253,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T03:34:14.124Z","checkpoint_height":35253,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
