Distributed Energy Data Sharing and Privacy Protection Based on Blockchain Technology

Energy Internet must be realized on the premise of broad consensus and trust among the participants, therefore, there is an urgent need for a technology that can not only easily and quickly construct distributed applications, but also achieve trusted interaction at a low cost. Aiming at the improvement of the underlying technology and architecture of blockchain in the current energy blockchain research field and analyzing the existing defects, this paper uses a distributed blockchain underlying architecture for energy trading scenarios. In this paper, considering the characteristics of energy transactions concentrated in geographical locations, a transaction scheme based on hierarchical construction of the general ledger by the main sub-chain is presented. The paper studied the transaction confirmation path and data fragmentation storage strategy based on concurrent construction for massive energy transaction data. In different cases, the above scheme is realized and its effect is verified. Compared with photovoltaic power generation, the situation of wind power generation would have some differences, the peak of wind power generation in the afternoon, the user's power generation at 14 o'clock., 15 o'clock peak. In this paper, the key data structure, key algorithm, technical implementation and automated distributed trading scheme in the energy trading scenario are preliminarily described, and their key performance indicators are tested. The key technologies in this paper can be better applied to the energy trading scenario.
