Under the name of VOLTEX, we are developing a blockchain-based energy management system with an integrated peer-to-peer trading platform. This system measures, controls and regulates the power grid to the base frequency of 50 hertz. Thus, the users of VOLTEX save costs, energy and relieve the power grid. By integrating the blockchain technology into the electricity grid, transparent proof of origin in real time is revolutionizing electricity trading. VOLTEX focuses on energy-intensive industries and therefore follows a top-down approach. We are the first company that has managed to develop a hardware which comes into use from the high voltage level down to the low voltage level.
