Trust Requirements in Blockchain Systems: A Preliminary Study

The focus of this position paper is to study and identify trust requirements in blockchain systems. So far, we have found that the overall trust-related requirements engineering knowledge is far from what is needed for successful engineering of various trust-related challenges in blockchain systems. We have identified an urgent need and challenge to revisit requirements engineering models to effectively include trust requirements; and to produce a trust engineering taxonomy, models, and techniques for achieving and fulfilling blockchain system trust requirements and goals.
