GridSingularity facilitates an Internet-based decentralized energy data management and exchange platform built on blockchain technology. GridSingularity accommodates a range of energy market participants, from regulators to operators, investors, traders and consumers. The new platform supports forecasting for grid balancing (smart grid management), facilitate investment, trade of green certificates/certificates of origin and energy trade validation. By recording the relevant data in real time at the source (power plant) on the blockchain, the proposed system diminishes the counterparty risk since data can no longer be modified, while decentralized storage ensures that the data generator has exclusive access to own data. The data recording process is to be certified by the respective energy regulators to validate arbitration. The main advantage of the platform lies in its interoperability,
