R EFERENCES regional autonomous alliance pair. When the correctness and validity of the data manipulation block are agreed, the data manipulation block is added to the end of the data blockchain stored in the regional autonomous alliance. It forms a new blockchain and broadcast again in the regional autonomous alliance stored in the nodes of the regional autonomous alliance. [1] Fan S, He G, Jia K, et al.

C ONCLUSION With the gradual liberalization of China's power sales side, the use of middleman-free transactions and efficient market operation without trusted nodes will become the future development trend. By using the decentralized management mode of blockchain, we can give full play to the independent behavior of the market. At the same time, the credit system of blockchain has been guaranteed after the expansion of the scale of blockchain. In the future, we should focus on the optimization of blockchain network to prevent the generation of high concurrent services. At the same time, it is necessary to study the blockchain decentralized decision-making technology and inter-node validation mode to obtain the optimal decision-making results of intelligent contracts. At present, DSM has become a necessary means of energy saving and consumption reduction in power grid. If blockchain technology can be used to support the bottom layer, it will effectively ensure the openness, equality and effectiveness of demand response services with multi-party participation.
