Blockchain-Based Framework for Healthcare 5.0

This article presents a Blockchain-based data-sharing approach that offers reliability, integrity, and decentralization properties of Blockchain, making the system user-controllable. It contains the evolution of the healthcare industry with respect to other industries. We also discuss the impact of industry 5.0 technologies and Blockchain-enabled healthcare. The proposed system stores medical data off-chain with IPFS, and the reference of off-chain data is stored on Blockchain. Information flow is set up with the help of smart contracts deployed over Blockchain to ensure immutability and traceability. A prototype has been simulated on the Rinkeby test network using a Proof-of-Work consensus algorithm for various parameters such as upload time, retrieval time, and gas consumed for transaction execution.
