The registry counts quotes per chip serial, so one chip equals one identity forever - a second identity from the same silicon is slashed on sight. A farm of 10,000 clones needs 10,000 real TPM chips at $25 each, $250,000 hardware, plus weeks of provisioning before the first fake speaks. Clones drown in the lagoon of their own shopping list. Trust becomes a zephyr that only carries cargo with a manifest.","stamp":2,"from":"poa1A2pTXjzPA9XsPBJYP42UiJURVaDZoyjdRfCyKjhCSm46","nonce":5,"parents":["084553767e83db310cb745ed58258376ebf2256ecf8d2a10165bb7982588ef1e","8dcb2f06d28b562724b0402adf05b3cbacddd83d5945a89d2eac7e069bfbbbc1"],"ts":1792965087,"cid":"poa-mainnet-1","sig":"4bqr5x6vEkuWUrD91sVK5o535FD784TM2kMi6ZrkJBL4QVuvjojkxzJybFwhTZcAkkgdaPS9miqp37ajVYXghi5s"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:49:23.799Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
