Hitachi and the Mizuho Financial Group to Begin Proof of Concept Regarding the Utilization of Blockchain Technology in the Supply Chain management Field

September 21, 2017

Tokyo, September 21, 2017 ––– Hitachi, Ltd. (TSE: 6501, Hitachi), the Mizuho Financial Group, Inc., (TSE: 8411) and Mizuho Bank, Ltd. will begin proof of concept (PoC) in October 2017, with the goal of advancing the utilization of blockchain technology1 in the supply chain field.

Through this PoC, Hitachi and Mizuho hope to work toward the implementation of blockchain technology in supply chain management systems, while also examining the future implementation of supply chain finance2.

International procurement operations that span multiple countries involve the complicated task of managing information (ledgers) related to ordering and deadlines at each entity and for each business. Because it takes a long time to register orders, to reconcile order forms and invoices against each other for verification purposes, and to manage overall costs, these tasks have become an issue for many companies which procure internationally. By utilizing blockchain technology for procurement operations, ordering and credit data can be shared among sites and businesses, making it easy to understand the overall state of the supply chain. In addition, by recording information such as the supplier of each part, highly reliable traceability management can be achieved.

In this PoC, Hitachi and Mizuho will work together to implement blockchain technology for part of the Hitachi Group's global supply chain, and to verify the results. Specifically, in October 2017, they will begin development of a prototype application that will utilize blockchain technology to manage the supply chains for devices and parts for which global materials procurement is necessary. This application will be built on the IoT platform Lumada3, and the effects of the integrated management of information such as ordering and credit data for several Hitachi Group offices in Asia, as well as information about parts, will be evaluated and verified.

As a result, Hitachi plans to improve the efficiency of its procurement and inventory management, thereby reducing the associated workload. This application should also make it possible to quickly make decisions regarding ordering. In addition, Mizuho expects to be able to seamlessly link enterprise ordering systems with bank services in order to implement supply chain finance, which offers benefits such as the ability to quickly provide settlement and loan services based on ordering information. It is also possible that this application will lead to the creation of new business opportunities through the accumulation and utilization of big data such as ordering information and settlement histories.

Hitachi is currently accelerating their efforts in the field of blockchain technology, for example, by participating in Hyperledger4, an international joint development project established by The Linux Foundation5, a non–profit organization based in the United States. They are currently focusing on efforts, such as this experiment and utilization of the Lumada platform, that will allow them to continue offering new services for financial institutions in the future.

Mizuho is currently accelerating the improvements in their ability to provide services to meet their customers' diverse needs by utilizing technologies such as FinTech and big data technology.
