Requirements Elicitation for Applications Running on a Blockchain - Preliminary Results.

Blockchain has been one of Gartner’s Top 10 Strategic Technology Trends for several consecutive years. The technology has evolved from a platform allowing transactions of cryptocurrency between peers (e.g. Bitcoin) to a platform allowing the design of Decentralized Applications (DApps). Despite their growing popularity, little attention has been paid to the Software Engineering aspect of DApps. In this work, we aim to start bridging this gap by addressing the Requirements Engineering of DApps. We collect, analyze and integrate DApp user reviews in order to propose a first list of user requirements for DApps. The results can have practical implications for both practitioners and researchers. The former can use the results to guide them in the design of DApps, while the latter can see this paper as a first result to build upon to advance the software engineering field of blockchain-based applications.
