[Objective/Significance] As an emerging technology, blockchain has now been highly valued by the political, business, and academic circles of various countries, and related research results have shown a spurt of growth. In order to provide reference for the innovation and development of blockchain technology in China, this article analyzes the research status and development trend of the blockchain field. [Method/Process] The paper adopts the method of bibliometrics, with the help of text mining tools and visual analysis software to quantitatively analyze the relevant literature in Web of Science and CNKI. In order to explore the development status and trends of the blockchain field, the article analyzes the relevant documents in the two databases from the perspectives of annual publication volume, main research institutions, main researchers, main publication journals, research hotspots and research frontiers. [Results/Conclusions] Research conclusions show that China has strong scientific research capabilities in the field of blockchain, and has a number of high-impact scientific research institutions. However, the cooperation network of Chinese institutions and authors is relatively sparse, and the application field of blockchain technology is single. In the future, it is necessary to actively expand the application scenarios of blockchain technology and strengthen cooperation at home and abroad.
