【Abstract】Peer-to-Peer (P2P) energy trading platforms are being actively designed, tested, and operated by engineers, power distribution companies, and prosumers. The assurance of the accountability of the conduct of different stakeholders through a robust trust management mechanism is imperative in such platforms. The usage of blockchain, as an underlying technology, can ensure numerous properties, such as immutability, transparency, and traceable execution of transactions, in addition to ensuring trust establishment among different entities of the system. Few blockchain-based decentralized energy trading platforms have been designed in the literature to build trust about the platform and among prosumers. However, none of these proposals have considered human-in-the-loop in the trust establishment process. Moreover, these solutions have considered trust only at a particular layer of the blockchain, such as at the application or consensus layer. To bridge this gap, this article presents a novel cross-layer trust-based consensus protocol that considers human-in-the-loop and employs fuzzy logic to address the issue of vagueness of trust values by offering human interpretable trust level. The experimental results demonstrate the efficiency and effectiveness of our proposed protocol in comparison to established consensus mechanisms. The analysis also shows the protocol is immune against selfish mining, 51% and Sybil attacks.

【标题】使用模糊逻辑的点对点能源交易的基于信任的跨层共识协议
【摘要】工程师、配电公司和产消者正在积极设计、测试和运营点对点 (P2P) 能源交易平台。在此类平台中，必须通过强大的信任管理机制确保不同利益相关者的行为问责。使用区块链作为底层技术，除了确保系统不同实体之间的信任建立之外，还可以确保交易的不变性、透明性和可追溯执行等众多属性。文献中很少设计基于区块链的去中心化能源交易平台来建立对该平台和产消者之间的信任。然而，这些提议都没有考虑到信任建立过程中的人机交互。此外，这些解决方案仅在区块链的特定层考虑信任，例如在应用程序或共识层。为了弥合这一差距，本文提出了一种新颖的基于信任的跨层共识协议，该协议考虑了人在环，并采用模糊逻辑通过提供人类可解释的信任级别来解决信任值的模糊性问题。与已建立的共识机制相比，实验结果证明了我们提出的协议的效率和有效性。分析还表明，该协议对自私挖矿、51% 和 Sybil 攻击具有免疫力。
