The use of IoT offerings improves human existence in lots of approaches. Protection towards cyber threats is an utmost
important prospect of IoT gadgets operation. Malicious sports result in exclusive records leakage and incorrect performance
of devices turns into critical. Therefore, development of powerful answers that can protect each IoT devices in healthcare
facts and records exchange networks turns in to an actual venture. Aiming at some critical issues within the current
consensus algorithms, this paper proposes the verifiable random ranking (VRR) based Secure Blockchain Consensus (SBC)
mechanism to clear up the issues raised above. In comparison to standard algorithms, we reinvented methods to assess
node reliability and robustness and manage lively nodes. Our experiments display that the VRR–SBC algorithm has lower
consensus delay, higher throughput, improved safety, and lower verification charges. The simulation consequences show
efficiency of the blockchain era for restrained devices and give the opportunity to evaluate applicability limits of the
selected consensus algorithm.
