RQ3: What is the future of blockchain-based IoMT? Several substantial research gaps are revealed by the examination of relevant literature. The following problems must be addressed for the future:  
1. The solutions offered are proprietary. They do not create protocols to adapt diverse technology and foster interoperability, preventing their adoption.
