Digital Currency Payment Method, Apparatus, and System

A digital currency payment method, applied to a first client and comprising:

• sending a transaction amount to a first currency management apparatus corresponding to the first client, so as to enable the first currency management apparatus to divide, in a case where the transaction amount is less than a denomination of a first digital currency used for payment, the first digital currency into a third digital currency and a fourth digital currency, wherein a denomination of the third digital currency indicates the transaction amount, and a denomination of the fourth digital currency indicates a difference between the denomination of the first digital currency and the transaction amount;
• receiving the third digital currency issued by the first currency management apparatus;
• and
• sending a payment request to a second client, the payment request indicating the third digital currency or a circulation identifier of the third digital currency, so as to enable a second currency management apparatus corresponding to the second client to cash, for the first currency management apparatus, a fifth digital currency corresponding to the third digital currency.
