Abstract Internet of Things (IoT) is the key of creating smart environment. It refers to the distributed objects as sensors and devices for exchanging information, due to its data centralization that is the main reason of a one-point failure and lack of privacy; it has been integrated recently with blockchain to raise the memory storage and security. Scalability has been figured as an issue for blockchain in large scale IoT due to the high load processing; therefore, we are proposing an architectural design for a scalable blockchain to be used in large scale IoT. Methodology of proposed design consist of expanding the blockchain by sharding technique where each node in the main chain has a sub chain and each node in sub chain has sub-sub chain that will enhance the process of creating a block on the chain in parallel with less time. © 2025 Proceedings IMCIC - International Multi-Conference on Complexity, Informatics and Cybernetics.
