The “Belt and Road Initiative” has strengthened political mutual trust and economic integration between China and other countries. With the development of blockchain technology，digital currency and electronic payment（DC/EP）bring in new factors to the current world economy. Because the traditional electronic payment mode fails to meet the requirement of the public，combined with the technical advantages of block chain，digital currency can improve the payment efficiency and reduce costs，and meet the needs of various application scenarios. In the view of the wealth transfer，this paper analyzes the emergence of future wealth，and infers four characteristics of future currency：credit based，with certain inflation，the mechanism of making wealth flow to the bottom and multi currency structure. It can be concluded that the digital currency project including Libra has a good momentum in the short term，but is still verified that it can be used as the world currency in the future. Based on the above background，China can grasp the historical opportunity to promote digital currency for the future，further promote the development of the “Belt and Road Initiative”，and empower the digital construction of the “Belt and Road” Initiative，and prevail in this global reconstruction and competition. Thus，we put forward a token-based bookkeeping model and relevant digital currency scheme，with high scalability，security and TPS，which is worthy as a priority infrastructure in China’s developing digital currency system.
