In terms of data transparency, provenance, authenticity, verification, data provenance, propositions, reliability, transparency, and safety, today's healthcare data management systems face significant hurdles. Blockchain refers to a decentralized network of computer nodes that may survive together without needing to rely on one another and preserve identical data. The use of blockchain technologies for the provision of safe and confidential healthcare managing data had also attracted considerable interest. In terms of accurate diagnosis and care through safe and secure intelligence sharing, blockchain is also converting traditional care methods into more dependable methods. Blockchain technology has the potential to contribute to personalized, authentic, and secure healthcare in the future by combining every actual relevant data to a particular patient and displaying it in a modern, safe healthcare environment. By using blockchain as a framework, we examine both the recent and current changes in the healthcare industry in this article. Together with problems and answers. This paper identifies challenges and opportunities for implementing blockchain technology in healthcare and summarizes health-related blockchain products and key players offering solutions across different applications. In doing this, our research extends and complements existing blockchain research in healthcare.
