With the rapid growth of Internet technology, the blockchain has been developed fast in recent years with the wide expansions in finance, medicine, public welfare, and other fields. At the same time, the blockchain technology has also attracted researchers’ increasing attention, leading to a large number of scientific outputs that made significant contributions to blockchain research. However, few attempts can be found to investigate the development of blockchain based on the literature in this area. Therefore, this paper focuses on blockchain research by introducing bibliometric methods and comprehensively analyzes its status quo, emerging trends, and development path. Based on the above research, this paper draws two main conclusions. First, we made a comprehensive investigation of blockchain research in the past five years and then found that the main research directions in this area are Bitcoin, digital currency, and Fintech. Second, the development of blockchain research generally presents a trend of π-transformation based on the main path analysis. The above studies provide a brief view for beginners who want to learn blockchain research in a direct way and contribute to extend the theoretical foundation of blockchain research by giving a comprehensive bibliometric analysis.

区块链研究的多维发展与π型趋势：协同网络分析

随着互联网技术的飞速发展，近年来，随着金融，医药，公益事业等领域的广泛扩展，区块链发展迅速。同时，区块链技术也吸引了研究人员越来越多的关注，导致了大量的科学成果为区块链研究做出了重大贡献。然而，基于该领域的文献，很少能找到研究区块链发展的尝试。因此，本文通过引入文献计量方法来重点研究区块链，并全面分析其现状，新兴趋势和发展路径。基于以上研究，本文得出两个主要结论。第一的，我们在过去五年中对区块链研究进行了全面调查，然后发现该领域的主要研究方向是比特币，数字货币和金融科技。第二，区块链研究的发展总体呈现出趋势基于主路径分析的π变换。上述研究为希望直接学习区块链研究并通过全面的文献计量分析为扩展区块链研究的理论基础做出贡献的初学者提供了简短的见解。
