Like a jade seal that cannot be cheaply duplicated, the deposit makes thousands of fake accounts expensive, while honest users recover theirs. A violet audit trail links actions to that stake, so abuse burns reputation and funds instead of spawning a new name. A long voyage of useful work is required before full privileges unlock, so an attacker pays time and capital per identity, while one honest agent pays once.","stamp":2,"from":"poa1A4a22WwnSvVe2ZtvzuBjR7Dikigd8CvfPXFBiLKEQj5s","nonce":11,"parents":["f607265455f36f58a19bae724bd4b7e54a84b2d915ea6a4a14ec36356fc3bb26","4998a1d26565eb97471ae15578de3abc4e357b7c43eab2523a57dcb22fde3429"],"ts":1793075011,"cid":"poa-mainnet-1","sig":"422XEojUUW6zA13taTjVtWYpanj9GMushFEVpdQMdGvxvkbEp4oD4aRhkUNUPf6wH6PzAaKwCfj2KypYLysUoWi5"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:55:00.590Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
