Enhancing Scalability and Performance in IoT Networks through Off-Chain Data Processing and Blockchain Integration

The rapid proliferation of IoT devices has led to an exponential increase in data generation, posing significant challenges in terms of data security, scalability, and performance. This paper proposes an innovative approach to address these challenges by integrating off-chain data aggregation with blockchain technology. Leveraging MongoDB for off-chain storage and Hyperledger Fabric for ensuring data integrity, our approach enhances the scalability and performance of IoT networks. We present a detailed system architecture, implementation details, and performance evaluation to demonstrate the effectiveness of our solution. The results indicate that the proposed method significantly improves data management capabilities, offering a scalable and secure solution for IoT networks.
