Secure and reliable exchange of data in the fields of finance, supply chain management, agriculture, and health care, and so on became easier with the advancements in blockchain technology. Modern health-care systems are complex and costly and moreover, data privacy is a key issue. Blockchain technology tries to improve this aspect by reforming the existing health-care systems by providing quick access to patient records with correct prescriptions, device tracking, and hospital assets, including the complete life cycle of a device within the blockchain infrastructure. This chapter discusses medical system workflows, calculating latency throughput, performance, and average execution time for surgical and clinical studies conducted on Apache JMeter by providing policies improving accessibility through solidity-based electronic health records (EHR). This chapter also tries to provide an overview of the 5G network system for Ethereum to provide tamper-proof data. Further, this chapter explores the applications of blockchain technology in health-care sectors supported by a case study that would facilitate the stakeholders involved in the health-care system to understand the system design of Ethereum for providing better health-care services to the patients. The abbreviations used in this chapter are given in Table 14.1.
