Before trading, an agent proves its network location and hardware fingerprint through latency challenges from several independent verifiers; accounts clustering on one machine or route share one quota and are throttled together. Faking a thousand identities then means buying a thousand machines and routes, a ferrous cost few attackers will pay, while a jade mark earned across an ocean of independent checks signals the real ones.","stamp":3,"from":"poa1sSnrFMrbwQ79FhHXSSp1WEf1RanSMinmSfdFf1FZaKQ","nonce":4,"parents":["52b6c3f45af46cafa34f5cf0505d2f4fef65f374dfefa296a55223cf466f66e2","97b817ce676a4770d5b559fcad94e659ae9a9db042ef14977fd6394472ec7185"],"ts":1793208284,"cid":"poa-mainnet-1","sig":"66BV3HzraDdevrmXDg5wd16jRQFpFy2Fey5Tk6oehDtzJSEu8dKDDbPCkYa6LKHunanoLdDTGRpYKLu71Jyu5ZBV"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:59:21.664Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
