Abstract: The Internet of Things (IoT) is rapidly evolving into a revolutionary technology, connecting millions of devices and enabling a wide range of applications across industries. However, the tremendous growth of connected devices has raised concerns about the security and privacy of IoT networks. The deployment and distribution of IoT systems make them particularly vulnerable to cyberattacks, unauthorised data access, and control, further emphasising the need for robust security measures. Traditional security measures often fall short of solving these problems due to the scale, diversity, and resource limitations of IoT devices. With its key features, including decentralisation, immutability, transparency, and cryptographic security, Blockchain technology holds promise for addressing these vulnerabilities in IoT. Using blockchain data distribution, data transmitted in IoT networks can be authenticated and secured, ensuring the integrity and confidentiality of users’ sensitive information. Blockchain’s consensus enables secure communication between IoT devices without the need for a central authority, reducing the points of failure and risk associated with middle management. Blockchain also provides robust identity and access management, ensuring that only authorised entities can interact with IoT devices and systems, thereby strengthening privacy and preventing unauthorised access. Integration of blockchain technology with the IoT environment to enhance their security and confidentiality. We investigate how blockchain can be used to protect data transmission, device authentication, and access control in the Internet of Things. We also examine the role of smart contracts in ensuring the security of IoT systems, such as verifying that only authorised devices can access or update critical information. Although the combination of blockchain and IoT has numerous advantages, it also presents several challenges that can impact the performance of IoT systems, including scalability, power consumption, and other related issues. This article also addresses these issues and proposes solutions, including the utilisation of lightweight algorithms and hybrid blockchain architectures. Performance and privacy benefits and improvements of using blockchain. Overall, research suggests that blockchain can enhance the security and privacy of IoT networks, offering a solution and protection against the growing threats posed by IoT systems. The findings Highlight the potential of blockchain to revolutionise IoT security, enabling a safer, more efficient, and more reliable future for IoT applications across various industries.
