Abstract - This revolutionary study presents a complete theoretical framework aimed at improving the cybersecurity of the Internet of Things (IoT) through the use of blockchain technology. The theoretical foundation focuses on essential principles such as decentralisation, consensus processes, and cryptographic procedures, drawing inspiration from various research works across disciplines. The fundamental goal of this paradigm is to address and mitigate security and privacy concerns in the field of IoT by calling for a shift from centralised to decentralised systems. Using blockchain’s inherent capabilities, the framework presents a breakthrough for proactively combating growing security threats. The cryptographic features of blockchain, in particular, are used to develop novel solutions. This framework investigates unique technologies such as encrypted communication routes and decentralised identity management. These cutting-edge technologies seek to strengthen the security infrastructure of IoT ecosystems by providing strong defenses against potential vulnerabilities. Furthermore, the study investigates the theoretical features of several blockchain applications designed expressly to improve Internet of Things security. Exploration of these applications provides useful insights, improving a better understanding of the theoretical foundations supporting the proposed framework. Despite its theoretical nature, the study report emphasises the importance of transforming theoretical capabilities into concrete advances in the rapidly evolving IoT sector. The call to action emphasises the importance of practical implementations that may effectively solve real-world cybersecurity issues. However, the research highlights limits such as scalability and interoperability, which must be considered when implementing the suggested framework in practical contexts.
