Digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking authority defines virtual currency as: the digital expression of value, which is not issued by the central bank or authorities, nor linked with legal currency, but because it is accepted by the public, it can be used as a means of payment, or can be transferred, stored or traded in electronic form. Digital currency can be considered as a virtual currency based on node network and digital encryption algorithm. The core characteristics of digital currency are mainly reflected in three aspects: first, e to some open algorithms, digital currency has no issuing subject, so no one or institution can control its issuing; ② Because the number of algorithm solutions is fixed, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the overuse of virtual currency; ③ Because the transaction process needs the approval of each node in the network, the transaction process of digital currency is safe enough. The emergence of bitcoin poses a great challenge to the existing monetary system. Although it belongs to the generalized virtual currency, it is essentially different from the virtual currency issued by network enterprises, so it is called digital currency. This paper compares digital currency with electronic currency and virtual currency from the aspects of issuing subject, scope of application, issuing quantity, storage form, circulation mode, credit guarantee, transaction cost and transaction security.
