Blockchain technology was first introduced in 2008, and since then it has been a subject of interest for both academicians and practitioners. Blockchain has many applications in business areas, such as: cryptocurrency, supply chain management, human resources management, music industry, real estate management and much more. Despite the growing interest in blockchain technology, the literature regarding it is relatively new and limited. In the context of technology adoption studies, especially in blockchain field, there are limited number of studies that investigate innovation adoption at the organizational level. This paper proposes a model that integrates diffusion of innovation theory, technology-organization-environment framework, and institutional theory for future blockchain adoption studies at the organizational level.
