摘要：Abstract Currently, it is difficult for China's electricity trading platform to handle large amounts of data during centralized clearing, achieve cross‐regional sharing of transaction information, and realize the optimized allocation of resources. The previous research has proposed establishing a new distributed electricity market trading platform based on blockchain technology to solve the aforementioned problems; however, transaction nodes on the platform have difficulty determining the final delisting plan in the face of numerous choices. Therefore, in this study, a search engine was designed according to the demands of the delisting node. The developed algorithm is run with a programmed script through a smart contract and can provide the best delisting plan for delisting nodes, ensuring that the delisting plan is selected intelligently and publicly. Overall, seven delisting strategies were designed. Additionally, the improved Critic‐G1 method based on the coefficient of variation was used to establish a smart contract for the comprehensive evaluation of listing nodes. Finally, the example analysis verified that calling the smart contract can help the delisting node quickly obtain the best delisting strategy, increase the enthusiasm of the transaction subject, and facilitate the promotion and application of the transaction platform based on blockchain technology, confirming the effectiveness of the proposed method.
