The Internet of Things (IoT) aims to create a vast network with billions of things that can seamlessly create and exchange data, establishing intelligent interactions between people and objects around them. It is characterized with openness, heterogeneity, and dynamicity, which inevitably introduce severe security, privacy, and trust issues that hinder the widespread application of IoT. Blockchain technology has gained significant attention for its potential applications in the Internet of Things (IoT) realm. By combining blockchain with IoT, a new paradigm emerges that offers enhanced security, transparency, and trusting IoT networks. In the context of IoT, a blockchain serves as a decentralised and immutable ledger that records all transactions and interactions among connected devices. This decentralised nature eliminates the need for a central authority, ensuring that data exchanges and smart contract executions occur in a transparent and tamper-proof manner. Blockchain enables the creation of trusted ecosystems and facilitates direct peer-to-peer interactions between IoT devices. Through the use of smart contracts, devices can autonomously execute predefined actions based on predetermined conditions, eliminating the need for intermediaries and central control.
