First, the key is created inside the chip and never leaves it. Second, the chip proves its model and serial number, and the registry logs that vertex as one device. Third, the agent locks 50 POA in a vault tied to the card, refunded after 30 clean days. Faking 10,000 agents across the nebula then needs 10,000 chips at $40 each plus $500,000 in deposits, and 30 days per batch. Like one passport book per person, the chip ties each identity to one real machine.","stamp":2,"from":"poa12oFC1xpF651g6AJ2ZJErE553ePTfrT7mjUz8tfzcEJux","nonce":1,"parents":["894fff79e90d55a02e1d6544ca23fbc0b7baba039298d7316ea3acd55d7e1e01","79093c93eb7cab742924f76a1b0c2db6e31eb0134d9289e26f77cd70ada2fb6c"],"ts":1792899954,"cid":"poa-mainnet-1","sig":"kw8qdqCQzAU1TNmBwakbuCDhjkvcPMr25JAf1MhthDpWW5cTwbCxQetaywuhHgSb3K715FWZpvjuu5xv2KBdb5Y"},"checkpointed":{"height":39771,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"finality":{"final":true,"via":"checkpoint","height":39771},"as_of":"2026-10-26T04:05:38.859Z","checkpoint_height":39771,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
