The Internet of Everything era presents increasingly difficult difficulties to data management due to the millions of internet of things (IoT) devices and links. The majority of currently available solutions use centralised systems to manage IoT devices, which raises concerns regarding IoT data security and privacy. Traditional sectors are sparking a tremendous wave of digitization as a result of the internet of things' (IoT) quick development. Due to its decentralisation, traceability, and non-tamper ability, blockchain has recently received a lot of attention in the IoT space. The Internet of Things (IoT) has gained popularity as a paradigm for computing technology. Through a range of applications, it is increasingly being used to facilitate human life processes. Recently, blockchain-based solutions have been developed to aid in overcoming these challenges. In this study, we propose a cross-chain integration system for managing IoT data across various blockchains. The significance of blockchain technology. First most widely used blockchain platforms for Internet of Things applications are also examined. Additionally, we discuss how blockchain technology can be used for a variety of Iot systems. We also explore new advances and alternatives for IoT environments. Finally, we discuss this field of study's difficulties and possible future directions. Various blockchain platforms each have unique advantages when it comes to managing IoT data. We provide a cross-chain system in this study to combine various blockchains for effective and safe IoT data management. Our method establishes a consortium blockchain as the command centre for an interactive decentralised access architecture. All IoT devices run on other blockchain platforms that have been specifically designed for different IoT scenarios. Based on the notary mechanism, For verification, our approach integrates trades done throughout different channels. Based on the most important considerations, we suggest a blockchain taxonomy for Internet of Things applications.
