An Approach to Elicit Trustworthiness Requirements in Blockchain technology

Abstract The leading Blockchain technology facilitates in many sectors including finance and healthcare. However, some technical challenges such as fraud and hacking arise may impact trust of users towards this technology. Requirement elicitation is one of requirement engineering activities to determine system requirements through discussion with stakeholders from documentation and underlying domain before executes it to development stage. The available methods for eliciting requirements, such as interviews and brainstorming are found to be time-consuming, and they fail to identify trustworthiness requirements. Further, eliciting requirements for Blockchain application is found to be challenging, as the properties of Blockchain application are different from the common technology. Moreover, the common elicitation practices are lacking on considering trust elements when eliciting requirements. Therefore, this research aims to propose a new automated elicitation approach which is a library for trust requirements of Blockchain application. A new trust taxonomy will be identified to classify and analyse the association between trust factors and its attributes. A proof concept prototype tool will be developed to realize the approach. Finally, this new approach is expected to enhance the acceptance of people towards application developed using Blockchain technology. Furthermore, this study will provide positive results in producing sustainable Blockchain application or software.
