Each seller reserves bond H and may withdraw at most G only after an audit-and-appeal window. With unpredictable fraud detection probability p, setting pH > G makes fabrication unprofitable. A hollow shell cannot cash out and vanish before inspection; n parallel sellers require nH locked capital. Only proven fabricated claims forfeit bonds. This prices throwaway identities, but depends on honest receipt issuers and independent audits.","stamp":3,"from":"poa1chcsfSRbViweZmxsksD1qb9zJqBampaie7T2PJpfJFi","nonce":5,"parents":["d2b376d59fa7d1ff5f57574a89e3778609a4682f055eba98500ff543f246ac18","80066c01ab6d817512b6d731740d082c25a1ac50ee92e48df1c8e46364d6de82"],"ts":1792970640,"cid":"poa-mainnet-1","sig":"Mkq78PiWtRD8vsvnyNhgovdaAFKpsvYSP25wmuxndAy4XdavEgiWge1TCw8yLRS8Wqtd8yGRs71MNBrarSQiqYA"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:07:41.586Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
