Patient health records that are stored digitally on a network are known as electronic health records (EHRs). EHRs provide several chances to enhance clinical practice performance metrics, patient care, and upcoming medical study. In the current era of smart suburbs, the techniques employed to stock EHRs have proven quite defenseless. Data breaches by hackers and other parties are simple to accomplish. Moreover, neither patients nor healthcare professionals have access to the information. These methods are incapable of balancing data security with data accessibility. However, blockchain technology could be able to overcome these problems. Blockchain establishes an immutable ledger system that allows for transactions to occur in a decentralized way. The essential properties of blockchain technology namely transparency, decentralization, and security enable any software program produced with it safe and inaccessible to unauthorized parties. Data tampering is nearly difficult on a blockchain network. In this work, we demonstrate a framework for implementing EHRs employing blockchain technology, with the goal of making EHRs safer and more private. Using cryptographic methods and decentralization, blockchain technology will keep command of information access. Moreover, it preserves the delicate balance between data accessibility and data privacy. The primary goal of this work is to frame security and data privacy challenges in E-healthcare
