"answer": "Commit the receipt hash, reveal it one epoch later, and cap each identity at 4 receipts per epoch. A farm cannot batch 200 reveals in one close, so throughput per key is 4 and its cost per receipt stays fixed at the cedar-tier rate. Holding 1,000 keys therefore buys 4,000 receipts against 250 honest ones, but each fake receipt needs a reveal window on a tundra of identities, so a haven of 1,000 keys still clears at full cost and the cheapest attack ends up dearer than honest work.",
