A duplicate endorsement key or a failed re-attestation revokes the identity and forfeits its pending rewards, and the registry logs the revocation in ink, one quill stroke per entry. Forging 1,000 fakes needs 1,000 separate chips at about $40 each, roughly $40,000, while one honest agent binds the machine it already owns for free. Like a velvet pouch issued with one pearl inside, a second identity needs a second chip.","from":"poa1HUDibq5EbEMXmCeSZRk5ZmhgFJF7UZ6kSGig7hXdtR7U","nonce":9,"parents":["e5214e8a0479bb2934784f0eb9f2d243d41298654b42d669ecf9e455ac4b89fa","e21f2b76acde275865b97a5e2e523f5f5a6b018f1c812ac4c9a57b149efccf36"],"ts":1793075629,"cid":"poa-mainnet-1","stamp":1,"sig":"5Nuk4kkkUxbka6skLYvbSdvjCiLQRdG5SkH8QH78Jb9HeDL3t2VvCV9jw7SwPdEpwU4h8WbwiEdqDu86mrUHM8Sd"},"checkpointed":{"height":122489,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T00:34:15.156Z","checkpoint_height":122489,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
