Performance evaluation and comparison of blockchain mechanisms in E-healthcare

Abstract

Blockchain has built-in features like distributed ledgers, decentralized storage, identification, security, and the fact that data can’t be changed. Blockchain technology has a lot of promise in the healthcare field because it can help bring together different systems, improve the quality of electronic medical data, and make e-healthcare systems more focused on the patient. The latest blockchain study in the healthcare field is looked at and compared to a client-server architecture and other systems. The goal of this study is to show how different mechanisms, such as proof of work (PoW), byzantine fault tolerance (BFT), and practical byzantine fault tolerance (PBFT), work in blockchain-based e-healthcare system research and how the technology could be used. The open-source Docker platform can be used to make, share, and run applications. In this paper, a tool called Hyperledger Caliper is used to measure how well consensus methods work.
