In Tokyo three districts communicate using blockchain

Daimaruyu is the Japanese district that connects three neighbourhoods in Tokyo, from the Imperial Palace to Tokyo Station. Developing over an area of 120 hectares which has been owned by the real estate branch of Mitsubishi for over 130 years, in early May it became the first blockchain-based district in the world.

The project, created by Fujitsu with the collaboration of SoftBank and the University of Tokyo, is designed to achieve the controlled and structured sharing of data, which is typical of blockchain technology; the process allows for data collection, distribution and analysis, encouraging cooperation between different companies and organisations. How does it work? Using blockchain to collect information from multiple sources - financial data provided by Mitsubishi through estate management, data provided by the IoT sensors of transport companies, shops, hotels and restaurants, together with payment system managers - it will be possible to study how people and financial transactions progress.

As explained also by Il Sole 24 Ore, as the various data bases are shared, people who will connect to Fujitsu’s blockchain network (paying on a workstation basis) will be gradually authorised (or not authorised) to access specific data and then reprocess them to create new services and products. The intended objective? To improve the satisfaction of both those who live and do business in the district as well as of the many tourists. The successful strategy? To be able to coordinate a huge quantity of data coming from heterogeneous sources and create useful and valuable information.
