The Internet of Things (IoT) has transformed the way we collect, process, and store data. However, the security, scalability, and transparency challenges that come with managing IoT data have become a major concern. In this research, we proposed an optimized blockchain model for secure and efficient data management in IoT environments. The proposed model uses a combination of sharding and pruning techniques to improve scalability, off-chain storage to reduce the storage overhead of the blockchain, and a custom consensus mechanism designed for IoT environments. The evaluation results showed that the proposed model can handle large numbers of IoT devices and data volumes, with good scalability, user experience, and integration capabilities with other systems. While the proposed model is an improvement over existing solutions in terms of security, transparency, and scalability, more research is needed to improve the model's functionality, validate its performance in real-world scenarios, and enhance its security and privacy mechanisms. Our proposed blockchain model has the potential to enhance data management in IoT environments, and could pave the way for a more secure and efficient data management future.
