Abstract: The swift expansion of Internet of Things (IoT) devices has resulted in unparalleled prospects for connectivity and information sharing. However, the pervasive deployment of IoT devices also give rise to security risks with the potential for privacy breaches and data vulnerabilities over the few years, the incorporation of Blockchain technology with IoT has shown to be a viable solution for overcoming these security challenges. The aim of the paper is contribute to the ongoing discourse on securing IoT ecosystems through Blockchain technology. The paper presents a review of the security threats, challenges in blockchain and IoT integration, issues and opportunities. It examines the potential of Blockchain as a solution to mitigate these threats, offering a detailed analysis of Blockchain-based security mechanisms and their integration with IoT environments. An examination of different consensus protocols and existing security techniques employed in Blockchain-IoT integration is presented. Additionally, the paper outlines evaluation parameters for assessing the effectiveness of Blockchain-based solutions in securing IoT infrastructures.
