— The Electronic Health Records system is an innovative platform designed using blockchain where the patient can have the power to securely manage, access, and share their medical records at their discretion. EHR provides an innovative solution that leverages blockchain technology, specifically Ethereum and Solidity smart contracts, to develop a robust and decentralized EHR system. Our blockchain-based EHR system empowers users to securely store and manage their health records while ensuring data privacy and integrity. Through the use of cryptographic keys and immutable smart contracts, patients gain control over who accesses their health information, thereby preserving confidentiality and enabling consent-based data sharing. EHR system extends beyond record-keeping, offering a telemedicine component that allows users to consult with healthcare professionals remotely. Smart contracts facilitate seamless, secure, and transparent interactions between patients and doctors, enhancing the overall quality of healthcare delivery. Furthermore, the fusion of blockchain technology, Ethereum, Solidity, and smart contracts in this EHR system signifies a transformative step forward in healthcare data management and telemedicine. The system not only empowers patients with control over their health data but also enhances the efficiency and security of healthcare services, ultimately advancing the quality of patient care in the digital age.
