Healthcare innovation is being aided by the Internet of Things (IoT). Nowadays, doctors and other medical experts can practice medicine anywhere, not just in hospitals. The healthcare industry makes use of IoT devices for a variety of purposes, including remote vital sign monitoring, private data transfer and receiving, and similar tasks. Cyber threat prevention should be the top priority when operating IoT devices. An urgent problem arises when malicious actions cause sensitive data to leak and equipment to malfunction. Protecting the data and record exchange networks of all Internet of Things devices has become a top priority. This work presents the Secure Blockchain Consensus (SBC) method, which is based on verifiable random ranking (VRR), as a solution to several serious problems with existing consensus methods. We came up with novel methods for controlling active nodes and testing their resilience and dependability instead than using traditional algorithms. Based on our testing, the VRR-SBC method increases security, decreases verification cost, and speeds up consensus. The simulation’s outcomes show that the blockchain era is helpful for some gadgets and let us evaluate how widely the consensus algorithm can be used.
