The rapid evolution of communication and data technologies has rendered traditional centralized cloud frameworks insufficient to meet the rising demands of data exchange within Internet of Vehicles (IoV) environments. Conventional vehicle network architectures, which rely heavily on trusted third parties (TTPs) for identity management, are prone to single failures and lack system autonomy. Blockchain innovation has emerged as a promising answer to these challenges. However, designing an efficient blockchain framework for IoV systems presents obstacles such as dynamic network configurations and resource constraints. This study introduces a layered resource leveling mechanism for blockchain-integrated IoV structure, enhancing system efficiency through optimal allocation of processing power. The efficiency of the novel method is showed by comparison with conventional ways.
