【Abstract】Integrating blockchain technology with Internet of Things (IoT) devices has great potential for a variety of applications, however, guaranteeing energy efficiency remains a significant challenge. This study aims to explore the development of energy-efficient strategies for the seamless integration of blockchain and IoT devices. This research focuses on lowering computational overhead and energy-intensive consensus procedures in order to enable a sustainable and optimal union of two potential technologies. This study introduces a new energy-efficient technique for ensuring the security of IoT devices. This newly presented approach combines blockchain with the code division multiple access (CDMA) algorithm to securely transfer IoT messages while consuming less energy. At the transmission end, data from many IoT devices are multiplexed using orthogonal codes that are distinct for each IoT device. The multiplexed data is then sent and fed into a blockchain network, which improves data security and integrity. The blockchain transfers the data to the CDMA receiver after completing tasks including validation, block generation, and transaction completion. For verification, the entire blockchain and CDMA-based IoT network is constructed. Experimental results indicate a significant reduction of up to 90% in energy consumption and up to 80% reduction in time latency.
