processes and thus patient outcomes. Blockchain can help in many ways; reducing transaction costs by using smart contracts which are embedded general purpose protocols to simplify procedures, reduce administrative burdens and remove intermediaries. Other blockchain e ff orts are aimed at improving the collection, use and sharing of health data from patients, researchers and sub-processors of data. Our proposed system uses blockchain technology to create a healthcare ecosystem that is iterative, scalable, secure, accessible and decentralized. This would allow patients to exchange their medical records freely and safely with doctors, hospitals, research organizations and other stakeholders-all while maintaining full control over the privacy of their medical data. This will solve many of the current healthcare system’s issues, including data siloing, legacy network incongruity, unstructured data collection di ffi culties, prohibitively high administrative costs, lack of data security, and unaddressed privacy concerns.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
