A Privacy-Preserving Blockchain-based Energy Supply Chain System Supporting Supervision

With the continuous development of science and technology, more and more energy has poured into human life and production activities. The energy supply chain is responsible for managing the entire life cycle of energy, but there are still some problems in the current energy supply chain. On the one hand, energy data lacks an effective sharing mechanism, and on the other hand, the privacy of user data cannot be guaranteed. In addition, different entities in the current energy supply chain system manage their data, and there will be data barriers, so it is difficult to effectively supervise and track energy data. Based on the consortium blockchain, this paper proposes an energy management system to provide a credible data collaboration environment for each entity in the energy supply chain. Data encryption ensures the privacy of data, better realizes the sharing of energy data, and breaks the data barriers between participants. The system uses smart contracts to set a unified data operation specification, and at the same time designs an energy management mechanism that is friendly to regulators, so as to better realize the supervision of the whole process of energy supply. Experiments show that the proposed system is practical.
