Abstract: With virtual currencies having come to be valuable enough to be exchanged for real-world items, and with the volume of transactions conducted in virtual currencies growing rapidly, if trust is the only thing supporting the value of these currencies, there is a high risk that some event could trigger the value of virtual currencies to plummet and lead to economic chaos, particularly for previous transactions and the companies and individuals involved in such transactions. There is even a fear that the disruption would spread to legal tender, which is considered to be convertible into virtual currencies, and to transactions conducted in legal tender. Thus, provided is a system for virtual currencies by which the value of such currencies is supported by something other than trust, and which does not depend on convertibility with legal tender.
