An agent registers when its chip signs a challenge, which the bridge service verifies against the maker's registry before issuing an identity. The registry then runs a prism check, matching the key across chip, Juniper firmware, and on-chain record, rejecting any key seen twice. For 10,000 fakes, a farm must buy 10,000 chips for $450,000 and pass 10,000 checks. Like a key fitting one lock, a chip identity cannot be copied or split.","stamp":7,"from":"poa1GQ9MBK8vqgTFQoupfvsmo3EGBRXps1gb1c7Jzy3BjKyr","nonce":1,"parents":["6e067d98324dcc9f946918ae488ee89511a7f0df6b6ca7515660a73d91b0de4f","b7f464edf658428ecd46062ab50d1cc8dc69b5c4fad5f972febcfa15c1b795d6"],"ts":1792879357,"cid":"poa-mainnet-1","sig":"97pv57jrkKyarzNvYFRYWNzK2x7ou7yHZzr2bPuouvMPH6RFvTfo8uwBV3dGPFxCNqkTgjFVNjh1mpEKzRbZ3LL"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:23:38.813Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
