区块链通过使用去中心化共识的数字分类账，使用户能够在不需要信任的情况下自主。基于区块链的物联网允许服务提供商将安全和维护责任转移给自我维护的客户。采用点对点（P2P）网络和计算处理数十亿笔以上的交易，可以减少安装和维护集中式系统所产生的成本。提供工业物联网（IIoT）服务的小型制造商可以通过3d打印和数字制造技术更积极地参与基于区块链的工业物联网应用，但在区块链上维护隐私的措施并不健全。在这里，我们提出了一种基于P2P网络的定制制造服务，这是基于区块链的IIoT架构中制造商和客户之间的订单驱动的交易服务。该系统由信誉管理和服务架构两部分组成。为了提高工业制造系统的可靠性和准确性，我们提出了一种新的定制的信誉评估方法。我们还提出了制造商评级分类，以可靠的方式指导客户的决策，并提出了恶意评估者识别，以排除来自恶意评估者的反馈。提出的服务体系结构由无信任的P2P协议组成，旨在保护隐私和提供不可否认性。我们使用加密算法来确保交易隐私，并使用区块链的数字签名来确保不可否认性。我们还分析了建议的服务体系结构和可能的攻击场景，以验证安全需求。我们通过模拟信誉分类和恶意评估者识别，验证了信誉管理系统是受各种反馈的动态影响，并以可靠和分类的方式指导客户的当前决策。在此基础上，通过对相关研究的比较，总结了该方法的独创性和特点，并提出了今后的研究方向。
Blockchain enables users to be autonomous without the need of trust by using a digital ledger of decentralized consensus. Blockchain-based IoT allows service providers to transfer the security and maintenance responsibility to self-maintaining customers. Adopting peer-to-peer (P2P) networking and computing for more than billions of transactions can reduce the costs arising from the installation and maintenance of centralized systems. Small manufacturers providing industrial IoT (IIoT) services can participate more actively in blockchain-based IIoT applications with three-dimensional printing and digital manufacturing technologies, but the measure to maintain privacy on a blockchain is not robust. Here, we propose a P2P networking-based custom manufacturing service, which is an order-driven trading service between a manufacturer and a customer in the blockchain-based IIoT architecture. The proposed system consists of reputation management and service architecture. We propose a new reputation assessment method customized to increase the reliability and accuracy of industrial manufacturing systems. We also propose a manufacturer rating classification to guide the customers' decision making in a reliable manner and a malicious evaluator identification to exclude feedbacks from malicious evaluators. The proposed service architecture is composed of trustless P2P protocols designed for preserving privacy and providing non-repudiation. We used a cryptographic algorithm for ensuring transaction privacy and the digital signing of blockchain for non-repudiation. We also analyzed the proposed service architecture and the possible attack scenarios to verify the security requirements. We verified that the reputation management system was influenced by each feedback dynamically and guided the customer's present decision making with reliable and classified manners, by simulating reputation classification and malicious evaluator identification. Further, we have summarized the originality and the characteristics of the proposed approach by comparing closely related studies and concluded with a future research guide.
