One of the top major banks in Korea, Shinhan Bank is piloting its first blockchain ‘PKMS’ to verify the information of the solar photovoltaic power system plants.

According to the announcement by Shinhan Bank on Dec 2, In order to record Solar Photovoltaic Power Information on the Blockchain, Shinhan Bank applied ‘PKMS ( Private Key Management System )’ to the renewable energy data platform “Redi”. The system is jointly developed by Shinhan Bank, Kakao’s blockchain technology affiliate Ground X, and Blockchain Technology Research Institute Hexlant.

By applying this system, it is possible to verify the Solar power information generated by the power plant, record it in real-time on the blockchain, and also can check the power amount.

Co-developer Hexlant will apply for the blockchain fintech project to the Financial Services Commission and the Regulatory Sandbox. One of the Shinhan Bank officials said, “It is meaningful that various Blockchain tech companies and reliable major banks have tried new business-to-business (B2B) models that build solutions and apply to other industries.”
