Blockchain in Healthcare System Using Hyperledger Fabric- a Comprehensive Review

A key component of the society structure is now medical healthcare. Understanding how to handle personal health data appropriately is becoming into an intriguing research issue because it is a vital and sensitive asset for each patient. In this overview, the solicitations of the Hyperledger Fabric blockchain with IoT devices are shown in order to limit access and create a chain of trust for the healthcare industry. Through encryption protocols, access controls, and cryptographic methods, the Hyperledger Fabric is designed to be safe against unauthorized access and use. In this study, a blockchain-based solution is defined following an assessment of the specifications for interoperability and solitude in the sharing of medical data. Considering its enterprise-grade data processing capabilities and other solitude protection features the Hyperledger Fabric architecture was evaluated. Our evaluation of the study's objectives and solutions is intended to help in the creation of an architecture or model that addresses the problems mentioned in the article. Another exciting subject that calls for more study is the solicitation of "blockchain and Internet of Things (IoT)" technologies in the healthcare sector. Network scalability is supposed to be enhanced by supporting low-end devices with patient-centric apps under smart contracts.
