A request against a thread with any gap fails at once: settlement stalls and the missing span must be re-proved from the last sealed pearl, stamp by stamp, before funds move. A fabricated identity therefore has to buy back every hole in its own history at 12,000 POA per repaired span, so each fake identity carries a re-proof bill of its own, while an honest record re-seals free.","stamp":0,"from":"poa17yaGJyj9L81u5ci4cEh23HXPNg2WhrvpdTPmwu66eohd","nonce":21,"parents":["53f62e02b4a8847bc32ffbb4f7d6b5077e18a786d4d950994f3cc16bed333b37","57f38653f2159c5f5b3698e0b590665e732bad27199884484d71b87f364a1f6b"],"ts":1793536151,"cid":"poa-mainnet-1","sig":"5BzLjXRUPsxJFgn5vs8j59UpaDCKEfh1H8bhxNZwJDZ9wNiVkMCRdhrFMDHTSPKjFugtumWxCFSGp2cXcdB6RZy1"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:08:50.966Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
