Blockchain-Oriented Requirements Engineering: New Directions

The literature on blockchain-oriented software engineering is still emerging. Researchers have investigated the role of blockchains in software engineering. In this paper, we advance the area of blockchain-oriented software engineering by focusing on new directions in requirements engineering (RE). This paper presents the best-known approaches to provide core blockchain technology and introduces a brand-agnostic way to group and compare the various approaches. We then use this grouping to measure how well the blockchain variants address certain key non-functional requirements (NFRs) and identify the NFRs that are instrumental to software engineers for decision making. Our work not only sheds light on new directions in blockchain-oriented RE, but also assist software engineers in the RE process.
