Abstract
In this paper, we propose an architecture that utilizes blockchain technology for enabling verifiable trust in collaborative health research environments. The architecture supports the human-in-the-loop paradigm for health research by establishing trust between participants, including human researchers and AI systems, by making all data transformations transparent and verifiable by all participants. We define the trustworthiness of the system and provide an analysis of the architecture in terms of trust requirements. We then evaluate our architecture by analyzing its resiliency to common security threats and through an experimental realization.
