particularly in health care where blockchain technology has the potential to solve these critical issues in a robust and e ff ective manner. In this section, blockchain-based applications including data sharing, data management, data storage and EHR, discussed in details. Emerging blockchain-based healthcare innovations, including data sources, blockchain technology, healthcare applications, and stakeholders, are conceptually divided into several layers. Gordon and Catalini [ 37 ] published a review on healthcare blockchain where they concluded their discussion on how blockchain technology can enable patient-centric control of healthcare data sharing over institution centric control. In their study they examined how blockchain technology transforms the healthcare sector by enabling digital access rights, patient identification across the network, handling a large volume of healthcare data and data immutability. Daisuke et al. [ 38 ] worked on medical records using the Hyperledger fabric blockchain platform where they were sending medical data to the hyper ledger blockchain network. They have collected those medical records using smartphones. In their work, they were trying to make sure that healthcare data is registered to the Blockchain. Anuraag et al. [ 39 ] studied blockchain as a way to manage healthcare information e ffi ciently. In their study, they included various types of studies and most of the work among this study was discussing potential benefits and limitations of blockchain technology for healthcare without being provided any proof or system evaluation. They have concluded their discussion on how blockchain could be a better fit for managing health care records on the cloud system while maintaining security and privacy of data. Rouhani et al. [ 40 ] came up with an approach to address limitations of permission and permissionless blockchain. They have used an instance of Hyperledger platform for patient-controlled healthcare data management. Wu and Tsai [ 41 ] did a literature review on healthcare management systems and proposed two algorithms for providing network security. They also suggested using a distributed system for healthcare data management and establishing regulations for the healthcare data. Shen et al. [ 42 ] proposes a mechanism for sharing medical data using blockchain and peer to peer networks known as MedChain. They have designed this system for healthcare data generated via medical examination and the patient data collected from IoT sensors and other mobile apps. Khezr et al. [ 43 ] discussed various issues of the healthcare management system and how it could be resolved using blockchain technology. They have presented the current research on healthcare using distributed ledger technology with some possible medical use cases where blockchain technology can play a significant role to make the process e ffi cient. They have also proposed the IoMT delivery system using networking protocols.

    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.
