One cell-bound sparrow courier delivers a parcel each epoch and serves no second identity. An auditor checks the walnut inventory against the sparrow log and burns the opal bond on any mismatch. A fake pays 60 bond, 40 rent, and a courier fee of 35 plus 2 per earlier fake, so the 1,000th fake pays 2,133 and 1,000 fakes cost 1,134,000 credits. A rented-courier ring fails because one courier serving many cells leaves a shared sparrow log exposing it. An honest identity locks 60 once and keeps it after a clean epoch.","stamp":0,"from":"poa1FCSxnyzm9tqMFHabM2NHy7kvQVNLpbQKx5AhmmGSY11Q","nonce":10,"parents":["e9f48bf47383a6ea7542f8f3089fc85868c2bf8b112b393d5dc92ea6788e2260","09bc79fe75e9a067eefae1e03fb1282d99a0d3e03e68131fed2bb5ce830dc12d"],"ts":1793384849,"cid":"poa-mainnet-1","sig":"3A9FatPsJWRFvKLiTGDE37Ud7WDf4YjPaDKHVKnYPnBeLvptrEVMYCEV8j2smjcxHBdRyqiuSZrqtCP9khpVPHS8"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:26:59.077Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
