In the Industrial Internet of Things (IIoT), peer-to-peer (P2P) distributed energy (DE) transactions exist in various scenarios. This paper attempts to improve the intelligence, real-timeliness, and security of the direct transaction between DE generation companies (DEGCs) and users, and reduce the default frequency of distributed power (DP) transactions. For these purposes, a P2P DE transaction model for the IIoT was proposed based on blockchain. Firstly, a blockchain-based distributed energy peer-to-peer transaction framework is constructed, which is more suitable for generalized energy transactions based on typical transaction scenarios of the IIoT. Using credit value evaluation and smart contracts to ensure the transparency, openness, and non-tampering of credit scores. On this basis, the energy currency reward mechanism is used to promote the trustworthiness of transaction nodes and maintain transaction security. Finally, the P2P direct transaction based on credit value was designed to improve the transaction efficiency and security. Through case analysis, the DE transaction model for the IIoT, which is based on the credit value of the blockchain, supports fast and frequent energy transactions, as it overcomes the confirmation delays of energy blockchain transactions. The proposed model improves the efficiency of DE transactions in the IIoT, effectively suppresses default frequency, and maintains the order of DE market in the IIoT.

在工业物联网（IIoT）中，在各种情况下都存在对等（P2P）分布式能源（DE）事务。本文试图提高DE生成公司（DEGC）与用户之间直接交易的智能性，实时性和安全性，并减少分布式电源（DP）交易的默认频率。为此，提出了基于区块链的IIoT的P2P DE交易模型。首先，构建了基于区块链的分布式能源对等交易框架，该框架更适合基于IIoT典型交易场景的广义能源交易。使用信用价值评估和智能合约来确保信用评分的透明性，公开性和不篡改性。在此基础上，能源货币奖励机制用于提升交易节点的可信度，维护交易安全。最后，设计了基于信用价值的P2P直接交易，以提高交易效率和安全性。通过案例分析，基于区块链信用价值的IIoT的DE交易模型支持快速，频繁的能源交易，因为它克服了能源区块链交易的确认延迟。该模型提高了物联网中DE交易的效率，有效抑制了违约频率，并保持了物联网中DE市场的秩序。通过案例分析，基于区块链信用价值的IIoT的DE交易模型支持快速，频繁的能源交易，因为它克服了能源区块链交易的确认延迟。该模型提高了物联网中DE交易的效率，有效抑制了违约频率，并保持了物联网中DE市场的秩序。通过案例分析，基于区块链信用价值的IIoT的DE交易模型支持快速，频繁的能源交易，因为它克服了能源区块链交易的确认延迟。该模型提高了物联网中DE交易的效率，有效抑制了违约频率，并保持了物联网中DE市场的秩序。
