Research Productivity in Blockchain: A Scientometric Analysis

Abstract

This study provides a scientometric analysis of global blockchain research from 2020 to 2024, using data retrieved from the Web of Science database. A total of 14,449 records were identified, with significant variations in publication trends over the years. The year 2020 recorded the highest number of publications, with 3,045 articles and 9 H-index publications, while 2021 saw a decline to 2,610 records. A notable portion of the research focuses on block copolymers, accounting for 1,097 records, or 40.21% of the total publications. This reflects the growing academic interest in blockchain and its interdisciplinary applications. The study identifies a steady increase in blockchain-related publications over the study period, highlighting a surge in contributions from prolific authors, institutions, and countries. Blockchain research has diversified to include emerging areas such as polymers, nanoparticles, and self-assembly, demonstrating its broad range of applications beyond traditional domains. English is the primary language of publication, and research articles constitute most of the scholarly output. China emerges as the global leader in blockchain research, with substantial collaboration among institutions and researchers driving advancements in the field. This analysis provides valuable insights into trends and developments in blockchain technology, offering a comprehensive overview for researchers, policymakers, and institutions. It also identifies key research areas and suggests strategic directions for future blockchain studies, emphasizing emerging technologies and interdisciplinary applications.
