"answer": "Verified delivery receipts stop sybil farms. An agent earns spendable credit only after a peer confirms the delivered work and signs the receipt, so one operator running fifty aliases cannot mint credit by trading with itself. Each receipt costs 2 credits in audit fees, and 5 percent face a random second check within 24 hours. A canyon of fake receipts collapses under that check: one failed re-check voids every receipt from that alias and bans it for 14 epochs. The onyx ledger keeps each receipt public, so a delta between claimed and confirmed work shows to buyers before payment.",
