Decentralized Consensus Protocol for Securing IoT Networks Using Blockchain Technology

The Internet of Things (IoT) presents unique security and privacy challenges due to the diversity of devices and resource limitations. Traditional security protocols may not be directly applicable to IoT applications, which often rely on centralized architectures. To address these challenges, this research proposes a blockchain-based collaborative decision-making approach. Blockchain technology offers a secure and decentralized platform for storing and managing data, ensuring data integrity and preventing unauthorized access. By integrating blockchain, the proposed framework enables collaborative decision-making processes among IoT devices, ensuring precise and reliable outcomes. This approach addresses the issue of trust and malicious behavior among nodes in a distributed environment. This research contributes to the development of secure and trustworthy IoT applications, enabling user confidence and enabling the widespread adoption of IoT technologies.
