The early exploration of the energy blockchain has provided good technical support for the construction of the energy internet. However, as the continuous influx of large-scale participants, the safety, fairness and efficiency of energy transactions once again face new challenges. Game theory considers the advantages of strategic interaction and interest dependence between transaction subjects, and is expected to provide new solutions. Firstly, the objective function of maximizing the benefits of energy trading is to construct a multi-energy trading strategy game model. According to energy supply and demand and quotation, the Nash equilibrium value of the strategy game between energy users and energy providers is solved, which provides a price reference for the trading mechanism. Combining the characteristics of the energy internet, this paper builds a weakly centralized multi-agent energy transaction mechanism based on the alliance chain, and improves the energy block structure and consensus mechanism to achieve an efficient and reliable transaction process. Simulation results show that the secure transaction mechanism not only protects the interests of buyers and sellers, but also speeds up the consensus of the block, with a view to provide help for the construction of the energy trading platform.

Key words: energy internet, blockchain, game theory, secure transaction mechanism, consensus mechanism
