Electronic health records (EHRs) are compassionate information shared securely with different healthcare providers. Our goal with this chapter was to create a system to store and share EHRs securely using blockchain technology. Blockchain technology is decentralized, immutable, and guarantees non-repudiation of the data. These properties make an opportunity to develop an EHRs system using Blockchain. This chapter has surveyed the relevant related work regarding blockchain technology and the different consensus protocols applied to the Blockchain. The various existing blockchains and platforms that enable the development of decentralized applications are meticulously detailed in the related work section. Health applications that explore topics affiliated with this work, such as using the Blockchain to solve issues with the current healthcare services, were also studied and detailed. This chapter also explained the system model and all the 140 implementation considerations to enable the electronic health records of a user to be stored so that the user can access his data and provide it to the different healthcare providers at any time. The proposed architecture, MedicalBlockchain, allows stored data to be viewed, inserted, altered, shared, or deleted by certain entities depending on defined access policies. MedicalBlockchain improves how medical records are shared by ensuring data and owner privacy, service availability, data immutability, and access control management.
