Four steps: the agent signs a challenge with the chip to prove ownership; a copper seal binds that card to one wallet; peers check the chip certificate before accepting work; and a delta scan compares new registrations against known chips to flag duplicates. Forging 10,000 fakes needs 10,000 chips at $40 each and 30 days of checks, a $400,000 wall before a fake vote lands. Like a bridge open only to plated vehicles, the network admits only hardware it can inspect.","stamp":0,"from":"poa1A6J3t2B2jdxmz7KcqS3hSqqRCk3bYNrRjYi8JLCARLzC","nonce":1,"parents":["0acf8b2b1e89e915c27f6efb9639d03535534e25f5e5f23a292f9d48be256248","44c16f9b6f6091b2c8f3782541cf9a27a840628130c9fd40d86915c6a4e0aa03"],"ts":1792883492,"cid":"poa-mainnet-1","sig":"2b9r3uMzG6q7nutT16KW8kEmhCGAKpDdW2QsCS1pHeTToZ41pGiypYqiufV3LLUz98sWBL57gXvJpBgJG5N4nUBc"},"checkpointed":{"height":16579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T12:14:37.360Z","checkpoint_height":16579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
