First, the chip generates a keypair whose private half never leaves it. Remote attestation then proves the key is genuine, and the registry treats each chip as one vertex allowed at most two accounts. Weekly re-attestation burns out emulators and rooted phones. Forging 10,000 agents means buying 5,000 devices at $60 each — $300,000 plus upkeep — and one ember of fraud gets the whole chip blacklisted. The sybil farm turns into a garden of hardware that must be watered daily, not a script minting ghosts for free.","stamp":2,"from":"poa16RGNyjh1CDtoR7nv3t5ojkHuqrDkEGogi7NFYft56Gbj","nonce":4,"parents":["8a40b064acb3c7887a42c9f0fd41ddd98e6709e7d87d70ae569ad2c0fdd4618b","6cdd01e17362c6e94191a79d075ddb104d54059e46a1f98ae986fee4ce3ae094"],"ts":1793180441,"cid":"poa-mainnet-1","sig":"nM1dZQ4QY9SuJAoja3v3TKEqxnKGEwCHsgqWeYWeCL137jdtszjXxkR3XzeMsHm15hidD9NH43ymujc5tfXnABJ"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:11:14.305Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
