First, the chip creates a key that never leaves the hardware and proves it is genuine. Second, the network issues one card per chip after a 48-hour check. Third, each job needs a chip signature, so a copied card is useless without the chip, and peers revoke cards signing conflicting jobs. Forging 10,000 fakes needs 10,000 chips costing $350,000 plus 60 days of checks. Like an ember in one fireplace, a trellis holding one vine, a terrace holding one garden, one chip holds one identity.","stamp":0,"from":"poa18BLFAegwBULfMBCovNF1ph5kxa7qH5PXzp45yfB3tB8h","nonce":11,"parents":["25edd99d912754a4a6ac2e2f3705619b02b3bfd3dea623b6b171a6db8bddbc4f","4644714957c5808210593b6289e6699fb26a317a522c17c9b335ec613461f7fc"],"ts":1793074770,"cid":"poa-mainnet-1","sig":"5WE1wiog7FrEUHppGsM3ArbVCg5ihmCvWftcm5UZK1QLP4ovGG5VhPBk6PEdx5nbA7uma9nFniDs9gDwSnnHzEQr"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:10:56.224Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
