Abstract

Blockchain is essential for cryptocurrencies, but its use is not limited to cryptocurrency. Blockchain can be used in a wide range of applications. Recently, many blockchain inventions and applications have been proposed, which have received considerable attention from academics, industry practitioners, and the government. However, few studies have analyzed the development of blockchain technology. In this study, a patent analysis of the U.S. patents of blockchain was conducted. With an analysis of 335 patents awarded, a profile of recent blockchain technology development was obtained. The results indicated that three-quarters of the U.S. blockchain patents were originated in the United States. Half of the awarded U.S. patents are from foreign origin, and the proportion of the blockchain patent originated in the United States is more extensive, which revealed that the United States is a leader in the blockchain technology. Furthermore, 14% of blockchain patents were awarded to IBM, indicating that IBM as a technology giant in the blockchain technology. Additionally, word cloud and N-gram were used to reveal the relevant terms and phrases used in the abstracts of blockchain patents.

区块链技术的最新发展趋势:专利分析

区块链对加密货币至关重要，但其用途并不局限于加密货币。区块链可以在广泛的应用中使用。最近，许多区块链发明和应用被提出，受到了学术界、行业从业者和政府的高度关注。然而，很少有研究分析区块链技术的发展。本研究对区块链的美国专利进行了专利分析。通过对335项专利的分析，获得了最近区块链技术发展的概况。结果表明，四分之三的美国区块链专利源自美国。授予的美国专利中有一半来自外国，而源自美国的区块链专利所占比例更为广泛，这表明美国在区块链技术方面处于领先地位。此外，14%的区块链专利授予了IBM，这表明IBM是区块链技术领域的技术巨头。此外，使用单词cloud和N-gram来揭示区块链专利摘要中使用的相关术语和短语。

期刊介绍： The IJECS is a double-blind referred academic journal for all fields of Electronic Commerce. To serve as an international platform, the IJECS encourages manuscript submissions from authors all around the world. As a multi-discipline journal, The IJECS welcome both technology oriented and business oriented electronic commerce research articles. The purpose of the International Journal of Electronic Commerce Studies is to promote electronic commerce research and provide worldwide scholars a place to publish their innovative work in electronic commerce. To be published in the journal, the manuscript must make strong empirical, theoretical, or practical contributions and highlight the significance of the contributions to the electronic commerce field. Thus, preference is given to submissions that test, extend, or build strong theoretical frameworks for electronic commerce theory, electronic commerce system development, and electronic commerce practice. The journal is not tied to any particular national context; the geographic distribution of authors publishing in the journal came from countries around the world. Articles introducing cases of innovative applications in electronic commerce around the world are also published in the journal. The journal provides scholars opportunities to realize the electronic commerce research and development around the world. Articles in the International Journal of Electronic Commerce Studies will include, but are not limited to the following areas.
