DeCurret to Hold a Study Group on Digital Currency Settlement Infrastructure in Japan

DeCurret Inc. (HQ: Chiyoda ward, Tokyo; President & CEO: Kazuhiro Tokita) has today announced that it will hold a study group with the goal of building digital settlement infrastructure using valuable digital currencies in Japan. The study group will comprise participants from three megabanks (Mizuho Bank, Ltd., MUFG Bank, Ltd., Sumitomo Mitsui Banking Corporation) and major Japanese companies, experts, among others.


In recent years, expectations have been growing about the efficiency and convenience of digital currency settlements befitting digital society against backdrops such as businesses issuing digital currencies using distributed ledger technology and actions taken by some central banks. At the same time, concerns are emerging over issues including privacy protection, crime prevention measures, and technology risks. These have resulted in the needs for a direction for the realization of valuable digital currencies in Japan.


The purpose of this study group is to examine and discuss challenges and solutions concerning digital currencies and digital settlement infrastructure, to find a consensus toward their realization, and to present a direction for standardizing services and infrastructure.
