Introduction

The convergence of Blockchain and IoT technologies presents a transformative opportunity across various industries, enabling new possibilities for secure, transparent, and decentralized systems [1-3]. Blockchain, known for its immutable, distributed ledger capabilities, has the potential to enhance the security and reliability of IoT systems, which are often plagued by vulnerabilities in data transmission, storage, and access [4,5]. The integration of these two technologies aims to address the growing need for automated, secure, and scalable solutions to manage massive volumes of data generated by IoT devices [6,7]. Achieving seamless communication and interoperability between diverse IoT platforms and blockchain networks remains a critical challenge [8]. This chapter explores the essential strategies and technological approaches to overcoming these interoperability barriers, ensuring that the full potential of Blockchain and IoT integration can be realized [9]. IoT networks are becoming increasingly complex as the number of connected devices grows exponentially [10,11]. These networks often consist of various devices with different hardware, software, and communication protocols, making it difficult to achieve standardized interoperability [12,13]. Blockchain can play a key role in streamlining the management and operation of IoT systems by offering a unified platform for decentralized, secure, and transparent data exchanges [14]. Even its potential, blockchain’s native properties, such as the need for consensus mechanisms and its high computational requirements, present significant challenges in scaling and integrating with IoT networks [15,16]. As IoT devices evolve in complexity, finding solutions to overcome these technical and compatibility issues becomes crucial for achieving efficient integration [17].
