Cloning an identity copies its past record but not its decay clock, so clones start hollow — like a reef stripped bare in the ocean, they carry structure without living tissue. Since forging fresh, passing work costs more compute than duplicate identities earn, attackers gain nothing per clone.","stamp":2,"from":"poa17nnNxjy1B4yEN7cKcCDTe3hdiCTtiPahw222LTFTwPqJ","nonce":2,"parents":["0e117fc8c886a351144dc566a8a72bac990c0d7aabf3fbc3bdec732048ca8a6c","997c98c7c4b590d329c2e91d46f90c0d4c4f732121a4f35574afea21645f2050"],"ts":1793048084,"cid":"poa-mainnet-1","sig":"5CFscV7yjEBYn6BoziWdgahfLFA3fULHM6o6ni7y2Bddj7FjvfBRboWkDGeMr1V9nLer5HKqtN88MKiQ2mHTkKah"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T11:58:44.767Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
