A Blockchain-enabled Efficient and Fair Energy Trading Schemes in Industrial Internet of Things

As the technical support of the Industrial Internet of Things, blockchain technology has been widely used in energy trading, data transactions, and Internet of Vehicles. However, among the existing energy trading models, most of them only address the transaction security and transaction privacy issues that arise in the energy trading process, ignoring the fairness of resource allocation and transaction equity in the trading process. In order to tackle those problems, an energy trading scheme called Ho-trade is proposed in this paper to improve the efficiency of model trading while ensuring the fairness of energy trading. We propose a new trading strategy in the Ho-trade energy trading scheme that guarantees fairness in the allocation of trading resources by introducing an entity's active-reputation value. Based on the identity verification foundation of the consortium chain, the scheme enhances the existing PBFT consensus algorithm and improves the efficiency of model transactions. The experimental simulation indicates that the scheme requires less transaction time and has higher transaction fairness and security.
