Research on Consensus Mechanism in Microgrid Transaction

With the development and wide application of new energy, the transaction information is huge. In this paper, a delegated power authority mechanism (DPPGC) is designed to achieve local block consensus, to ensure transaction security and the stability of the blockchain network. Through experimental simulation, it can be seen that the proposed DPPGC consensus mechanism can improve the security of the consensus and make the proportion of malicious nodes in the consensus node less than 20%.
