The Internet of Things (IoT) has experienced massive growth in recent years, which has resulted in considerable issues in terms of data integrity, scalability, and security. The traditional architectures that are centralised have a difficult time managing the increasing number of devices that are connected to one another while maintaining trust and efficiency. However, the significant processing cost and scalability concerns that blockchain technology presents present constraints for Internet of Things applications. Blockchain technology provides a system that is both decentralised and immune to tampering. In order to overcome these difficulties, this article provides a framework for the Internet of Things that is both safe and scalable, and it makes use of a layered blockchain architecture. Multiple blockchain layers are integrated into the framework. At the edge, a lightweight and high-speed blockchain is responsible for managing Internet of Things transactions. At the centre, a more robust blockchain is responsible for ensuring the integrity and security of data. Through the utilisation of this hierarchical technique, transaction processing efficiency is improved, latency is decreased, and resource utilisation is maximised. The most important technological difficulties, such as consensus procedures, data management, interoperability, and energy efficiency, are studied by us. In addition to this, we investigate potential solutions such as lightweight cryptographic protocols, optimised consensus algorithms, and cross-chain communication methods. Based on the results of performance testing, the framework that has been suggested is a suitable option for Internet of Things applications that are used in the real world since it enhances security, scalability, and efficiency.
