Abstract: The research on blockchain-based hardware simulation platforms, the design of control architecture implementing data interaction between blockchain and smart devices, and the evaluation of the performance of energy blockchain under the influence of various physical factors in the real environments are the basis for analyzing the applicability of different blockchain architectures to distributed energy trading. To simulate the operating states of park-scale distributed energy prosumers, a cyber-physical simulation platform for distributed energy trading is designed and implemented with a four-layer architecture of hardware layer,control layer, network layer, and blockchain layer. Among them, the hardware layer is implemented based on a real physical model, representing the actual power entities; the control layer implements the data interaction between the hardware layer and the blockchain layer; the network layer defines the way of node connection; the blockchain layer adopts the proof of authority（PoA）consensus mechanism, which is responsible for matching and recording energy trading. Finally, a complete energy blockchain architecture is formed combining the software and hardware to support the transformation of the "energy flow" of the smart device into the "data flow" of blockchain. The simulation results show that the designed simulation platform can realize the performance testing of energy blockchain systems, and the Ethereum PoA consensus mechanism can meet the performance requirements of distributed energy trading.
