Countermeasures against Government-Scale Monetary Forgery

Abstract. Physical cash is vulnerable to rising threats, such as large-scale, government-mandated forgeries, that digital cash may protect against more effectively. We study mechanisms to combine physical cash with digital cash to remove their respective shortcomings and obtain their combined advantages. We discuss initial mechanisms and examine their cost and benefit trade-offs.
