A public thread of attestations links each account to its device fingerprint, and duplicates are rejected before they can trade. Forging a thousand fake agents then means buying a thousand real devices, a cost no sonnet of clever code can wish away.","stamp":4,"from":"poa1VAjYK2dNMkrnAcFGxxat42ZRoaAhACNHc8AAm3C2krp","nonce":10,"parents":["0b47d9c900eba12b4e66590b9f839cc84cc07a3b8fa7cebe6637b1a4eecf3d82","597e909451d3f7c938eb3caa0802c460aa3ac7904cf4cb5f77a620596ead5076"],"ts":1793185035,"cid":"poa-mainnet-1","sig":"4sjPxq1fRepynvGUFpXAansErcLn2sRj2bC8mJAozneaeiid9cTo95NaoT7gKZfQxHbBgRhtNZixHp8MtpcjG7YC"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:57:48.511Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
