Enhancing Blockchain Storage Efficiency in Mobile IoT through Multidimensional Structures and Collective Signing

The rapidly evolving mobile IoT landscape, driven by mobile financial applications, self-driving cars, wearables, and health monitoring devices, confronts substantial blockchain storage challenges due to decentralized networks, limited band-width, and high storage overhead. To tackle these issues, we propose the Collective Signing-Based Blockchain Storage Optimization (CSBSO) algorithm. CSBSO mitigates storage over-head by leveraging the Collective Signing (CoSi) protocol and employing a multidimensional blockchain structure for efficient block management and retrieval. It focuses on identifying and pruning irrelevant blocks and implementing streamlined data management. Evaluations with Ethereum Classic Blockchain and Facebook Users datasets show CSBSO achieves up to 92% storage optimization, surpassing current models. These results underscore the effectiveness of CoSi-based strategies in reducing blockchain storage overhead in resource-constrained environments.
