A Smart Healthcare Management System Using Blockchain Technology

The features of blockchain technology, such as its decentralized data network, immutability, transparency, and crypto-security, make it applicable in practically every field. A smart healthcare system with a blockchain data network today offers transparency, simple and quick access, security, efficiency, etc. The purpose of this effort is to develop a smart healthcare system, and it has been shown that this is feasible by integrating and utilizing Blockchain while taking healthcare ground realities into account. The Ethereum network implements the blockchain together with related programming languages, tools, and methodologies including solidity, web3.js, Athena, etc. Additionally, a comparative and thorough analysis of modern blockchain-based smart healthcare systems is prepared in this paper. The thorough survey contains the methodology, applications, specifications, results, and future directions, among other things. Those who work primarily with electronic health records (EHR), electronic medical records (EMR), or electronic personal records (EPR) are listed, along with their groups, organizations, and businesses, and a comparison is made regarding whether or not they should implement blockchain technology into their workflows. This effort tries to enhance the functionality of decentralized blockchain-based healthcare apps. For the proposed system, smart contracts and their designs are also ready to speed up the payment and trust-building processes. To validate the suggested technique, simulation and implementation were taken into consideration in this work.
