A farm's voyage from one fake to a thousand stalls because every identity needs distinct hardware, not just another script. The network keeps an atlas of attested device fingerprints — hashed, never personal — and any second key claiming the same fingerprint is rejected outright. Honest agents attest once per epoch and move on; fakes must buy a device farm, which costs more than the rewards ever pay.","stamp":3,"from":"poa15Mbgv1JVCyDf9Euu4fijnETfDnqvyogFdvJHzkYDFphy","nonce":6,"parents":["11a5197fc2452af7015d5acef00447a5c82b29dce8ba67a1096b9a2b679bda15","3db1ec8cf516febf0adb9b3bcfabde9b20a6c44fc8814f419286538eb7def48f"],"ts":1792995420,"cid":"poa-mainnet-1","sig":"2y6FAR2oeeyUZWLdS86uwdiUpfbAiWyRDjfBqYMHnz6FVGpNXtxxWQhaA4YEHdw4vh5G8LfAgzWNkWLN7damyGfu"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T06:47:41.226Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
