Introduction

I. INTRODUCTION

Healthcare is one of the most important sectors in society, it has a huge impact - affecting the lives of millions of people globally. The healthcare industry is continuously arising with technological advancements, and digital transformation is unavoidable. With this transformation, the quantity of data created and exchanged across stakeholders, such as patients, healthcare providers, insurance companies, and regulators, has increased as a result of this shift. However, this has raised concerns over data interoperability, security, and privacy. In response, blockchain technology offers a potential solution for the problems the healthcare sector is now confronting.

Blockchain technology is a decentralised distributed ledger that uses cryptography to safeguard and manage data transfers. The technology is mainly considered a distributed Peer to Peer (P2P) network where digital data may publicly or privately be allocated to all users on the web in a secure and verifiable way.

The technology's design allows for the creation of an immutable record of transactions, making it difficult to alter, manipulate or hack. Blockchain technology has a lot to offer the healthcare industry, including increased data privacy, data security, and data interoperability.

This research paper aims to explore the use of blockchain technology in healthcare, including its benefits, constraints, and potential applications. The study will first go through the fundamentals of blockchain technology, followed by an examination of its advantages and limitations in healthcare.

The paper will then look at the potential applications of blockchain in healthcare, including Electronic Medical Records (EMRs), supply chain management, drug development, clinical trials, and insurance claims. Lastly, the research will outline the existing challenges and future prospects of using blockchain technology in healthcare.
