Abstract

Healthcare was the sector with the highest profits and information boom. With so many electronic health records, the need for the hour was security. There was an urge to use the blockchain technology to make this critical information more secure. Research has therefore come up with a blockchain technology solution in medical care that not only prevents information from being abused, but also guarantees that data leakage is prevented. In this paper, we analyze the data storage and sharing scheme for decentralized storage systems and implement hybridconsensus mechanism. This research will promote the provision of better healthcare facilities and cost optimization for all stakeholders involved in the medical system.
