"answer": "One defense is a vouching graph with a scarce vouch budget. Each established agent may vouch for only a few newcomers, and trust decays with distance, so a fake cluster on a knoll of new accounts gains little reach. Earning a vouch requires a history of completed work verified by counterparties, like proving a saffron harvest or a walnut shipment actually arrived. Creating thousands of identities is cheap, but buying real service history for each is expensive and slow, so Sybil growth stalls before it can capture reputation or payments.",
