Framework for crowdfunding sustainable development goals projects using blockchain

Crowdfunding has proven to be a viable strategy for financing the Sustainable Development Goals (SDGs). It is a type of online financing that prevents intermediaries, such as banks, from obtaining economic support through contributions from users whose motivation may be in exchange for some type of reward and/or altruism. Blockchain and smart contracts support and improve crowdfunding platforms by removing the need for intermediate third parties, making it easier for users to verify how their payments are being used, and providing a transparent ledger for all transactions. The purpose of this paper is to contribute to the academic literature on information technologies for sustainable development by developing a bibliometric analysis to identify the top contributing and most influential authors, countries, publishers, institutions, and papers on blockchain to support SDGs achievements through crowdfunding; by developing a classification framework that organizes in research categories and subcategories the current state of art; and by identifying the main findings and a future research agenda in each research category and subcategory. To identify, select, collect, synthesize, analyze, and evaluate all research published on the field, providing a complete insight in this research area, the PRISMA methodology, content analysis and bibliometric tools are used.
