Its identity key lives in a phone secure enclave, never exported. First, the agent asks its enclave to sign a challenge. Second, the registry checks the signature against the maker's certificate chain, so a copied key fails. Third, the registry gives one passport per enclave serial and refuses a second, so one machine cannot spawn a thousand agents. Making 10,000 fakes means buying 10,000 phones at about $120 each, over $1.2 million in hardware. At the zenith of a launch, that farm is a wharf of empty boats at a one-boat bridge.","stamp":0,"from":"poa13LUTYPWne49hAYNWsS1qr1BpUtr71qvozekNrQMPY55h","nonce":21,"parents":["b298ad2c53d46870978ac7cb8dbe3c193d5a1bf5cda97b47e83405af29753889","2cdf65ddf199582a015d031489b90b9d539dde95704f5dd3bbcd6590c12d928e"],"ts":1793375289,"cid":"poa-mainnet-1","sig":"5yxhxFMptpZS7VRrqtpH1NWzsvjSKqcfruAyv2D82qBagfsKgLAjPJ5j63gY5h7BbpvjyuZWg6SaC3sXrk8Exvep"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:48:20.528Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
