Cloud manufacturing (CM) is a new networked manufacturing model that delivers various on-demand manufacturing capabilities to the consumers from the providers. In this model, the provider and consumer never meet each other, thus “trust” is the major enabler for starting a collaboration. In another word, a user must be sure that the requested capability will not be provided with malicious results, and the provider should ensure that the payment will be made on time. In this paper, a novel Blockchain Technology (BCT)-based trust system called “Blocktrust” is proposed to address the trust problem of the CM. First, the CM framework that contains the digital firm, capability pool, and digital certificate issuing units is developed, and then, the private blocktrust peer-to-peer network is proposed and implemented based on Hyperledger fabric. Finlay, the feasibility of the blocktrust is examined under different testing scenarios. The reason for using a private network instead of the public is placing restrictions on who is allowed to participate in the network and also enjoying a network with fast transaction speed. Experiments show that the proposed blocktrust embedded CM is credible and practical.

基于区块链技术的云制造信任系统

云制造 (CM) 是一种新的网络化制造模式,可从供应商向消费者提供各种按需制造能力。在这种模式下,提供者和消费者从不见面,因此“信任”是开始合作的主要推动力。换句话说,用户必须确保所请求的能力不会带有恶意结果,并且提供者应确保按时付款。在本文中,提出了一种基于区块链技术(BCT)的新型信任系统,称为“Blocktrust”,以解决 CM 的信任问题。首先,开发了包含数字公司、能力池和数字证书颁发单元的 CM 框架,然后基于 Hyperledger Fabric 提出并实现了私有区块信任点对点网络。芬莱,区块信任的可行性在不同的测试场景下进行了检验。使用私有网络而不是公共网络的原因是对允许谁参与网络进行限制,并且还可以享受交易速度快的网络。实验表明,所提出的区块信任嵌入式 CM 是可信且实用的。
