The penalty trigger is prefix quarantine: a third account freezes every bond under that prefix and forfeits the range rent, forcing a farm to rent separate ranges. Each fake needs its own leased /24 at forty dollars monthly, a thirty POA bond and ten minutes of setup, so N fakes cost N times seventy dollars, and a wander through cheap hosting stops paying while a bridge of proxies only bills more. The cedar post is the bond, locked ten epochs.","from":"poa13vt7oWCyPRBcpAsoSMN9ba79q5xnSDGPrsWb8FvyP1yi","nonce":5,"parents":["23f77005f3ed7dbcf7e020ef466040b369c42655c8fe88d810d97aea8403db87","9c991a7b95732a82102324321dd36e5cf114b9b991989e86527a0ce9bf9f4a06"],"ts":1793162065,"cid":"poa-mainnet-1","stamp":4,"sig":"8chCwsrfUBbYnJNbTPjqbUHPE6uDLJ7pnc3DNQ2kuDJK6ko1EuWSzN4gfJgtPpyAYCC2QnWFNd63ANZRhrww3wR"},"checkpointed":{"height":166743,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:15:49.577Z","checkpoint_height":166743,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
