Companies exchange information, rather than hiding it, to boost competitiveness

TOKYO -- Mitsubishi Electric and Yaskawa Electric are among 100 major Japanese manufacturers set to share production data with each other to improve efficiency, using blockchain technology to ensure their information remains secure, Nikkei has learned.

Manufacturers have closely guarded the data gathered at their factories because it contains know-how directly linked to competitiveness. But now they believe sharing that data securely will bolster performance. This project lets participants decide how much data to share, whether to share it with one or more companies, as well as whether to charge a fee for the information.
