Abstract

To this day, many theorists regard the commodity theory and the credit theory as the two main rival accounts of the nature of money. Yet cryptocurrency has revolutionized the institution of money in ways that most commodity and credit theorists could hardly have anticipated. Given that cryptocurrency is a new form of money, the question arises whether the commodity and credit theories can adequately account for it. I argue that they cannot. I first offer an interpretation of the commodity and credit theories according to which these theories uphold differing claims about the origin of money, the ontology of money, and the function of money. I then argue that thus understood, neither theory can accommodate cryptocurrency. Finally, I develop a novel hybrid hylomorphic account of money which draws on aspects of both the commodity and credit theories, and I argue that this hybrid account can accommodate cryptocurrency.
