Blockchain technology has found application outside of cryptocurrency in recent times. The development of patient-centric storage of medical records on a blockchain has recently gained momentum. However, there have been few developments in providing a solution towards giving up full control to the public so that the concentration of power by only a small group of validators can be avoided. In this paper, we discuss a solution that enables patient-driven interoperability of medical records on a public blockchain while maintaining privacy using new cryptographic constructs and truly giving up control to the general public.
