Distributed Standardized Data Sharing Scheme Based on Blockchain for Power System

The security of the traditional data sharing scheme is generally based on the trust of both sides, less consideration of security, and generally need a trusted party for scheduling. However, in the standardization process of power information system, participating users are mutually distrusting, and it is difficult to balance decentralization, efficiency, cost and verifiability requirements. To address these challenges, we propose a novel data sharing architecture. The architecture of this paper can meet the key characteristics of distributed data sharing, namely decentralization, trust flow, supervision, and can realize the necessary security requirements of standardized data sharing. In addition, we deploy the scheme and implemented in two test networks of the well-known blockchain Ethereum. The results show that our scheme has better operating efficiency and stability, and is suitable for practical application.
