The Blockchain boom began with the debut of Bitcoin. The application of blockchain technology is expanding rapidly. Various sectors such as supply chain, logistics, research, healthcare, government, banking, media, and entertainment have already embraced this ground-breaking, decentralized technology. The healthcare industry is at the top of the list with significant blockchain potential. This article discusses the permissioned blockchain powered by Hyperledger Fabric and its privacy-preserving features like identity mixer, multichannel, private data collections, and transient field. This study considers the EHR systems scenario and proves how these privacy protection techniques of Fabric could protect the privacy of healthcare organizations' sensitive data. We evaluate existing studies on the use of the Hyperledger Fabric framework for EHR systems. We discovered that their implementation has data privacy and user privacy concerns that can be addressed in our future studies.
