What Do We Really Need? : A Systematic Literature Review of the Requirements for Blockchain-based E-government Services

Information Systems research acknowledges the importance of identifying requirements to ensure the artifact’s relevance. However, many research articles addressing blockchain technology for e-government capture the requirements that need to be fulfilled only implicitly by defining system objectives or evaluation criteria. Furthermore, focusing on specific use-cases encompasses the risk of overlooking those requirements, which are not as obvious but equally important. This procedure causes uncertainty regarding the requirements a blockchain-based e-government service needs to fulfill. Therefore, we conducted a systematic literature review on blockchain-based government-to-citizen (G2C) e-government services. On this basis, we categorized the requirements as we find that they address either the data of the system, the user, or the system itself. Our categorization provides a structured overview supporting researchers in conducting research on blockchain technology in the public sector and giving practitioners input to develop, test, and evaluate new blockchain-based G2C e-government services.
