摘要

The adoption of mobile blockchains in the Internet of Things (IoT) faces challenges due to high energy consumption, inefficient resource allocation, and privacy risks. Existing solutions rely on Mobile Edge Server (MES)-assisted offloading but suffer from suboptimal task allocation, load imbalance, and lack of privacy assurance. We introduce Privacy-ensURed game-based tasK offloAding in blockchAins (PURKAA) that uses tri-parametric task allocation (contextual priority, energy efficiency, and load balancing) and perfect matching for optimal resource distribution. Unlike Nash/Stackelberg-based models, PURKAA ensures efficient task allocation, \(50.6\%\) lower energy consumption, and stable throughput. It also enhances privacy using zk-SNARK-based transaction validation. Our evaluations on Hyperledger Fabric confirm \(100\%\) accurate and stable task allocation, reduced latency, and improved security. PURKAA is the first framework that optimally balances performance, energy efficiency, and privacy for mobile blockchain offloading, making it a scalable and secure solution for IoT-driven decentralized systems.
