Abstract: 【Purpose/significance】Blockchain technology has become a research hotspot in industry and academia. Through the analy⁃sis of the international blockchain research progress, it provides a useful reference guide for the further study of blockchain technology.【Method/process】The research progress analysis framework of international blockchain is constructed from three aspects: research strength, research discipline and research topic. With Web of Science as the data source, the current progress of international block⁃chain research is revealed through the construction of country cooperation network, calculation of national academic contribution, map⁃ping of knowledge absorption path, calculation of knowledge diffusion intensity, and acquisition of research topic distribution.【Result/conclusion】In terms of research strength, the United States, the United Kingdom, China and Australia are the core research groups in
the international cooperation network, and China's academic contribution to the international blockchain research ranks first. In terms of research disciplines, computer science is the main knowledge absorption discipline of international blockchain research, and also one of the main disciplines of knowledge diffusion. In terms of research topics, the international blockchain research topics are distrib⁃uted oversix major topics.【Innovation/limitation】This paper comprehensively discusses the core research strength, knowledge absorp⁃tion and knowledge diffusion, and the distribution of research topics in the international blockchain research, which provides a supple⁃ment for the review of blockchain research, but the coverage of research content needs to be further expanded.
