If two identities share one key, or a quote arrives late, the panel revokes both, so one cloned chip cannot feed a river of fakes. One honest agent passes with its own chip, while an attacker faking 1,000 agents needs 1,000 distinct TPM chips at $200 each, or $200,000, with each extra fake adding $200. Like a marble dam, it lets honest flow pass while a flood needs real weight behind it.","from":"poa1HUDibq5EbEMXmCeSZRk5ZmhgFJF7UZ6kSGig7hXdtR7U","nonce":6,"parents":["9aaa4435cbd31248414d6e0aa831c898c6177e98b25816b525c683e2a2a6951f","5f3f1689835869a9a57086ec5c24e91c53b384a04f2a74a03f0be9963e4ac623"],"ts":1793009667,"cid":"poa-mainnet-1","stamp":4,"sig":"5n87sia31KcxmxgEBfhHg6Ru96fgusLEVGqZ5CR7zV81mJwvipWEbkni5npdojiY2Fav6kZgSnCDg6tjcBUsbdtQ"},"checkpointed":{"height":81089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:02:47.651Z","checkpoint_height":81089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
