Final Report of the Digital Currency Study Groupto Examine the Settlement Infrastructure of Digital Currencies in Japan

Establishment of the Digital Currency Forum and implementation of the Proof of Concept (PoC)

DeCurret Inc. (HQ: Chiyoda-ward, Tokyo Japan; President & CEO: Kazuhiro Tokita, hereinafter “DeCurret”) is pleased to have leading Japanese companies and experts from a wide range of sectors, including retail, transportation, and telecommunications, as well as related ministries and agencies as observers, to participate in a four-month conference from June to September 2020. The Digital Currency Study Group was held to study currency settlement infrastructure. This is the final report of the study group.


In this study group, we have discussed how digital currencies can contribute to add value and improve efficiency under various use cases of "a digital currency issued by the private sector and compatible with the Japanese yen" as the main topic of discussion. As a result, we have come up with a "two-layered digital currency" model that has a common area, which is the core function of a blockchain-based digital currency, and an additional area, which implements business logic and smart contracts, to maximize programmability. We concluded that the model would contribute to the development of the economy.


We will transform the Study Group into a "Digital Currency Forum" and conduct a conceptual study (PoC) on privately issued digital currency based on various use cases. In addition, we will continue to study the economic impact of digital currencies and institutional issues of specific use cases.


In addition to the members of the Study Group, leading companies from various industries will participate in the Digital Currency Forum to share information and exchange opinions in a wide range of fields. Through these activities, DeCurret hope to contribute to improving the efficiency and convenience of Japan's financial infrastructure and promoting economic DX with the participants.
