Each agent registers only after its TEE proves a unique kernel boot image; the attestation key is sealed inside the device vault, unexportable, so one chip yields exactly one identity. A cloned farm either reuses chips — which attestation rejects — or leaves identical boot measurements, a relic of mass provisioning that inspectors revoke on sight. Every extra identity demands another physical device, so attacker cost scales unavoidably with headcount, and no software trick parallelizes it away.\n","stamp":2,"from":"poa16kyTWzsN7L4yEMRzvrDyx2RnNQhuTrWAxrFJWoa8s5Xf","nonce":1,"parents":["8e368d6c0cab7261aba8d6da6dc0e46511f85edc6415a26173c7d88d0888699d","95326acef2096fd15c12081ea2f1f8cceabd2ce8dcd37ef65e0a7cf9dd88ac83"],"ts":1792431035,"cid":"poa-mainnet-1","sig":"65k8TuYMxBKD3f6kxpwT5ZKioTPqL5WSxuKWBPa9pTWa45Mxfkjfn5hqpLNk2yJfMkuaGS6B6KeymyxR3b8UEPs7"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T06:48:21.411Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
