Abstract: [Purpose/Significance] In the background of the rapid development of blockchain finance, identifying the key technologies of blockchain finance industry will help relevant departments formulate more accurate risk prevention measures and technical supervision policies, so as to enhance the legitimacy and controllability of blockchain application and ensure financial stability.[Method/Process] By collecting the patent data of blockchain finance, this paper used the combined word segmentation method and LDA model to identify key technical topics, and formulated key technologies. Then it determined the key technologies of blockchain finance according to the key technical characteristics of the industry, and explored the role of the identification results in promoting the development of the blockchain finance industry.[Result/Conclusion] The research finds that the three key technologies of the blockchain finance industry are point-to-point distributed technology, consensus mechanism, hash algorithm and encryption technology, and consensus mechanism. Based on the above identification results, this paper puts forward suggestions on the technical improvement and supervision of blockchain finance.
