Blockchain technology for sustainable development: a systematic literature review

Purpose - Blockchain technology (BCT) is one of the latest disruptive innovations, brought along with-it immense scope of diverse applications contributing towards sustainable development (SD). The consistent increase in the publications reveal that the application of BCT for SD has become popular among researchers and practitioners in past few years, in turn, urged for a systematic literature review (SLR) to get an insight into the research journey travelled so far and setting directions for future research in this area. Therefore, this study aims to identify, map and synthesize the available literature on application of BCT for SD. Design/methodology/approach - The automatic and manual search resulted into 1,277 studies from Scopus and Web of Science database. Further applying inclusion and exclusion criterion resulted in bringing out total of 157 studies, which were termed as primary studies. Based on the results of descriptive analysis, conducted through Bibliometric and VOSviewer software, the characteristics of BCT and its key capabilities, contributing towards shaping the recent SD literature, were critically examined. Identified research themes for clustering primary studies were aligned with United Nations Sustainability Development Goals (UNSDG). A mind-map was also prepared on the basis of thematic classification of primary studies. Findings - The research themes "business practice and economic sustainability", "agriculture and food security" and "business practice and environment sustainability" were found to be the focal points of scholarly attention. Synthesis and analysis of primary studies resulted into classification of research gaps under four categories - theoretical foundation, methodological limitation, research themes and technology implementation challenges. The study was concluded by sensitizing and sanitizing the concrete research questions for future research. Research limitations/implications - The research findings shall be a roadmap for research scholars, academicians and practitioners to comprehend the present state of knowledge in the domain of "BCT application for SD" and decide upon adopting the future course of action to attain the UNSDGs by the year 2030. Originality/value - To the best of the authors' knowledge, the current study is the first attempt in its own sense to analyse and synthesize the available literature on "attaining SD through BCT" using SLR approach.
