With the speedy technological advancement and growth of sensors, WSNs have become the key technology for IoT. This inspires us to design our proposed system in a Multiwireless sensor network-based IoT environment. The main objective of our work is to provide a challenging standard of scalability, efficiency, and security in a multi-WSN system. With the intention of accomplishing our goal, we have implemented identity authentication based on hybrid blockchain technology. In this Distributed Multi WSN based IoT environment, the nodes are grouped into several ordinary nodes, cluster head nodes and base stations. In order to form a hybrid blockchain model, the blockchain network is created in among diverse types of nodes. On the one hand, the ordinary node's identity authentication is performed by the local blockchain. On the other hand, the cluster head's identity authentication is performed by a global blockchain. Thus, our intended private and public blockchain ensures extraordinary security and performance in the entire multi-WSN network. On the whole, our system proved that our proposed scheme has attained good security, scalability, and energy efficiency.
