Abstract

Blockchain technology supports a distributed and hybrid milieu with no requirement in the principal authority. The cryptographic principle makes the transaction secure and trustworthy in nature. In recent years, blockchain technology has come to be very popular in various contexts, especially due to the attractiveness of cryptocurrencies. In the healthcare sector, blockchain technology has emerged as a tremendous potential to develop an approach which is more patient-centric and can connect different systems to trace the disease quickly by getting more precision in electronic healthcare records. This paper discusses an advanced research and analysis in the context of healthcare. The main objective is to get the information about existing systems and their limitations and to seek a solution in the area of blockchain technology in the healthcare sector. The analysis approach consists of collection of data and its properties with a bibliometric review. The conclusion specifies that the use of blockchain technology in the healthcare system is cumulative and is also useful for the sharing of information, to trace health across the world. Hence, blockchain is playing a vital role in developing a system in the context of healthcare which will distribute information about diseases and manage the health of patients by keeping all their records.
