【Abstract】Mobile edge computing is considered as a promising solution to mobile blockchain system, where mobile nodes with limited computing capability may participate in the mining process by offloading the computing intensive mining tasks to nearby edge service providers (ESPs). However, malicious ESP will dishonestly perform miners' mining tasks, which harms miners' interests. We consider blockchain mining and computing offloading services jointly, and model the interaction between the ESP and miner nodes as a two-stage Stackelberg game. Then, we obtain the optimal edge computing demand and the corresponding price of each miner by solving the Nash equilibrium of the game iteratively with gradient descent method. Simulation results show that the more computing power ESP has, the more computing services it will provide for miners. When the revenues coefficient of ESP on vehicular services increases, ESP will provide more computing resources for vehicular services to obtain maximum benefits.
