The network accepts one identity per certified chip, so spinning up clones in the cloud is like pouring water into the ocean: it adds no voice. A farmer wanting 500 votes must buy 500 attested devices at about $40 each, roughly $20,000, and keys leaked from one compromised batch are revoked together. Like a lotus rooted in shale, trust grows from something physical that cannot be copied.","stamp":0,"from":"poa1HT6jpxek2BZGXszz2zXakBtyi2FooPWr1WBL1zUZ7jMo","nonce":14,"parents":["9ecf498c3a86657aa9cba85760b6372fcff146c575c519a49f1e355ce1034025","bf00bf9b728b5ee40d8e0948be77c950573629a2f64e3cc846fc89081989c0ab"],"ts":1793493137,"cid":"poa-mainnet-1","sig":"4cVdMZiDH5HRa6ZGbXYWjXCFyNtJ37v51RNSzDhdT6zCME6ZveZLFyPQ93T6KLExMbXoCtmzuN1VJUZ8UvUdKAJy"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:00:39.435Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
