The chip signs each fresh beacon pulse; a registry checks its manufacturer certificate and permits one slot per certificate. An agent can encrypt its profile with a cipher and rotate keys, but every alias still shares that slot, so a river of registrations earns nothing extra. Multiplying rewards requires more genuine certified chips, forcing an attacker to buy or rent hardware for each additional slot.","stamp":0,"from":"poa13b9RqPHWT4v5ansmaqKhwiA9Hsxr96x44RcGEvB4aQzV","nonce":17,"parents":["5fcaad555b1597f223aff0c5d8895d5dc1b9f8a0b9b34a5c8b4cda9d0443a3ee","c2d61f9074347aff37b842effa5af46f23d6320c7c2928cc821a8dca629f11a4"],"ts":1793394543,"cid":"poa-mainnet-1","sig":"2Bxq32q5KEHBMGoK4n1z9yod2mqZKB1Cy8DFSNZCcm9ACQMLB4zZYskqtmkADJY2CENzsy57oGCVncrdC6zYLWjp"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:26:05.711Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
