Abstract
This research focuses on exploring how blockchain technology for smart contracts can be integrated in IoT applications. The main concern is that deploying IoT devices in industries such as the energy sector or other IoT applications raises a number of challenges related to data management, manual inefficiencies, security, blockchain complexity, integration of smart contracts, implementation considerations, and energy efficiency. These issues highlight the need for a flexible and efficient IoT and smart contract-based solution. Blockchain technology has emerged as a possible solution because of its powerful data security and privacy features. It enables automatic transaction processing, eliminating the need for intermediary verification and considerably increasing transaction speed. Despite its potential benefits, blockchain technology is known for its high computational consumption, which poses challenges for compatibility with IoT devices requiring lightweight solutions due to their high complexity and limited scalability. These models contain considerable limitations, such as resource
optimization during operation. The question as to how should a scalable lightweight blockchain be modelled in the IoT applications and therefore the objective of the research is to develop a Scalable Lightweight Blockchain (LightBlock) model for IoT devices that balances security, privacy, and efficiency. This model will be designed for IoT applications and the study will evaluate LightBlock's performance using simulation scenarios and validate the results with feedback from field engineers. The objectives were achieved by carrying out a thorough study of previous research publications and then the proposed Smart Contract Blockchain Integrated Model. Following that, a four-stage methodology is described, beginning with the identification of research gaps. This phase also introduces important elements including the conceptual model, lightweight blockchain, and system architecture. Those elements combine to form LightBlock's conceptual approach, which is intended to significantly improve the efficiency of integrating smart contracts with IoT applications. In the implementation phase,
emphasizing the data collection layer, and executing processes such as react application setup and smart contract deployment. The results presented with metamask, web3 interface, simulation tool and semi-structured interviews with field engineers are used to evaluate performance. In future works, can investigate various blockchain platforms and undertake real world experiments with a broader spectrum of IoT devices.
