| dc.description.abstract | The rapid expansion of the IoT has led to the interconnection of billions of devices, but its reliance on centralized architectures raises critical security concerns such as data breaches, single points of failure, and trust issues with third-party servers. Blockchain, a decentralized and tamper-proof ledger, offers a promising solution to enhance security in IoT networks. However, a major challenge in integrating blockchain with IoT is the storage overhead, as resource-constrained IoT nodes struggle to store and verify the continuously growing blockchain ledger. To address this, the Memory Reduced Blockchain based Internet of Things (MERBIoT) approach is proposed, utilizing memory virtualization to optimize ledger access for IoT peers. This approach allows lightweight IoT nodes to dynamically retrieve blockchain records without requiring full storage, ensuring both security and scalability. Additionally, MERBIoT incorporates Merkle Tree-based integrity verification for tamper-proof transaction validation, sharding and optimized indexing to reduce storage burdens, and a dynamic data pruning mechanism to enhance retrieval efficiency and minimize redundant storage. | en_US |
