Sony and Fujitsu have developed a blockchain-based encrypted database platform for Japanese language proficiency documents. The database is claimed to prevent frauds related to Japanese language proficiency tests, as foreign students usually tend to attain fake documents to receive resident status in Japan. Using the blockchain-powered platform, certificates can be verified and authenticated with data registered on the blockchain, the company said.
Fujitsu has successfully completed trails on using blockchain to efficiently manage the inefficiencies in electricity supply, in collaboration with a local power disbursal company ENERES. The company implemented a blockchain-based Demand Response, an agreement between consumers and utility companies, to improve the success rate of power sharing. The platform is expected to efficiently manage the electric supply.
