Purpose This paper aims to make a thorough bibliometric analysis of blockchain technology in document verification in the education sector to trace the intellectual organization of the subject matter and suggest future research lines. Design/methodology/approach The data set comprises 1,054 papers located in the Scopus database. The performance analysis was applied to identify the best authors, best institutions, best countries, best journals and best publications. Moreover, VOSviewer was used as science - mapping methods to analyse the collaboration networks, keywords co-occurrence patterns, thematic clusters and citation patterns in the research field. Findings The analysis reveal that there are four significant thematic groups: (1) blockchain and related technologies; (2) integration with modern technologies such as artificial intelligence (AI), Internet of Things (IOT), machine learning and cybersecurity; (3) major security issues such as privacy, authentication, secure access control mechanisms; and (4) blockchain uses in virtual environments and protection of network infrastructure. The findings show that there is a great rise in interdisciplinary studies and international cooperation, as well as reveal research gaps belonging to multi-database studies and diversified use. Research limitations/implications The research is constrained to the papers that were included in the Scopus database, and this might be missing other studies that are relevant. Future research can use several databases and mixed research techniques to expand the range and level of analysis. Practical implications This study is innovative in that it advances the understanding of the conceptual and social structure of blockchain applications for document verification in the education sector by analysing the body of previous literature and offering insightful recommendations. Originality/value The research will offer a systematic and up-to-date bibliometric mapping of blockchain-based document verification in education research. It can provide useful knowledge to researchers, practitioners and policymakers and aid in the creation of verbal, intellectual and social infrastructure of the discipline, as well as facilitate the construction of secure and scalable verification systems in the educational ecosystem.
