Automation in smart manufacturing depends on many parties in the supply chain and distribution networks. A smart manufacturer needs to track the location and state of materials from its suppliers and products to its customers/distributors to manage the corresponding production schedule. The need for such information can be fulfilled by the use of Industrial Internet of Things (IIoT) devices installed at each respective party. However, even though all parties may trust one another, they have confidential data produced by the IIoT devices that are not allowed to be shared with other parties, or only allowed to be exchanged with certain parties. Even though the data are not confidential, they may still be required to share partial data based on the needs of each party. On the other hand, all parties have their independent systems that differ from each other, which leads to complex integration. Regarding those situations, a private-blockchain-based IIoT is promising to bridge the need for product and material tracking information exchange between parties while maintaining the respective confidentiality.

基于私有链的工业物联网，用于智能制造中的物料和产品跟踪

智能制造中的自动化取决于供应链和分销网络中的许多方面。精明的制造商需要跟踪从其供应商和产品到其客户/分销商的物料的位置和状态，以管理相应的生产计划。可以通过使用安装在每个相关方的工业物联网（IIoT）设备来满足对此类信息的需求。但是，即使各方可能彼此信任，他们也拥有由IIoT设备生成的机密数据，不允许与其他方共享或仅与某些方进行交换。即使数据不是保密的，仍然可能需要根据各方的需求共享部分数据。另一方面，各方都有各自不同的独立系统，这导致复杂的集成。关于这些情况，基于私有区块链的IIoT有望在保持各自机密性的同时，弥合各方之间产品和材料跟踪信息交换的需求。
