Blockchain technology is promising as a platform for providing solutions to global problems such as
(1) digital IDs for health services for refugees
(2) trading in decarbonised energy such as renewable energy and hydrogen ,
(3) low-commission, non-discriminatory international remittances
(4) management of supply chains and commodity markets
as the basis for providing solutions to global problems.
The energy trading system EDISON was developed and tested at a student dormitory at the Graduate School of Advanced Integrated Studies in Human Survivability, Kyoto University.
