A Stackelberg Game Pricing for Blockchain-Based Industrial Internet of Things Data Market

The vigorous development of the Industrial Internet of Things (IIoT) has brought massive amounts of data. In order to serve users more extensively and fully utilize the potential of data, it is particularly important to establish a fair and open IIoT data market. In order to enhance trust between data owners and consumers and facilitate transactions between the two parties, this article proposes a blockchain-based IIoT data market framework. To address another important issue in the IIoT data market: data pricing, we formulate the problem of maximizing the interests of the data platform, data providers, and consumers as a Stackelberg game pricing model. In this model, the data platform charges the data provider for data transmission, the data provider sells data to the consumer, and the consumer can determine the amount of data to purchase. The existence of Stackelberg equilibrium is proved by backward induction. Finally, the performance of the model was evaluated through numerical simulations.
