Conventional clinical data efforts are often siloed, however, which creates barriers to efficient information exchange and impedes effective treatment decision made for patients. This paper provides four contributions to the study of applying blockchain technology to clinical data sharing in the context of technical requirements defined in the \"Shared Nationwide Interoperability Roadmap\" from the Office of the National Coordinator for Health Information Technology (ONC).
