A Blockchain-based Electricity Retail Contracts Management System

With the development of the electricity market, the number of retail contracts generated by the electricity purchasers is increased rapidly. The traditional contracts management methods have gradually revealed disadvantages such as contracts loss, delayed update, and data tampering. As a result, the ensuing retail contracts disputes have also become more and more frequently. In terms to handle with such issues, we proposed a blockchain-based electricity retail contracts system, which utilizes immutability and traceability of blockchain. Leveraging the immutability and traceability of blockchain, our system can effectively store retail contracts which alleviates the problem of existing contract disputes. Moreover, we combine Inter-Planetary File System (IPFS) with blockchain to solve the storage problem. In addition, the data security of our system is guaranteed through the reasonable use of some means of authentication, digital signatures and access control.
