Abstract: The rapid development of mobile edge computing (MEC) drives the demand for low-latency, high-bandwidth, and energy-efficient computing in fields like the Internet of Things and intelligent transportation. Blockchain, a decentralized distributed technology, enhances MEC systems with its strengths in data security, privacy protection, and distributed management. The integration of MEC and blockchain leverages their complementary advantages. This study provides a systematic overview of the core concepts and technical characteristics of blockchain and mobile edge computing, establishing a foundation for understanding their integration mechanisms. Subsequently, it explores the key applications of blockchain within MEC, encompassing task scheduling, resource management, data security, privacy preservation, collaborative communication, and consensus mechanism optimization. Then, it presents representative case studies of blockchain-integrated MEC in domains such as vehicular networks, healthcare, and unmanned aerial vehicles. Finally, it synthesizes the existing challenges of this technological convergence and delineates prospective directions for future research.
