Production processes are becoming increasingly complex and decentralized, spanning across multiple manufacturing areas, factories, and even countries. Thereby is the development of a holistic and data-continuous traceability system, which provides transparency of records for the entire manufacturing flow from raw materials to the final product, one of the main challenges. While some solutions already address traceability issues in supply chain management and manufacturing, customized and volatile industries, in which each product features a unique configuration, are still lacking appropriate models and proofs of concept. In this research, we develop a decentralized blockchain application called TokenTrail, which focuses on the specific traceability requirements of multi-hierarchical assembly structures. The proposed blockchain architecture is based on a consortium Ethereum network and a Proof of Authority consensus, which delivers a trusted and shared database within an economic processing framework. To overcome the challenges of managing liaison transformations, we develop an assembly token manager based on the semi-fungible ERC 1155 token, which enables a direct representation of complex assembly processes and structures containing unique parts and batches within one smart contract. A user-friendly front-end application simplifies the querying of the recorded traceability data and visualizes existing dependencies.

生产过程变得越来越复杂和分散，遍及多个制造领域，工厂甚至国家。因此，开发了一个整体且数据连续的可追溯系统，该系统为从原材料到最终产品的整个制造流程提供了记录透明性，这是主要挑战之一。尽管一些解决方案已经解决了供应链管理和制造中的可追溯性问题，但每个产品具有独特配置的定制和易变行业仍然缺少适当的模型和概念证明。在这项研究中，我们开发了一个名为TokenTrail的去中心化区块链应用程序，该应用程序侧重于多层次装配结构的特定可追溯性要求。拟议的区块链架构基于以太坊联盟网络和权威证明共识，可在经济处理框架内提供受信任和共享的数据库。为了克服管理联络人转换的挑战，我们开发了基于半替代性ERC 1155令牌的装配令牌管理器，该组件令牌管理器可直接表示复杂的装配过程和结构，并在一个智能合约中包含独特的零件和批次。用户友好的前端应用程序简化了对记录的可追溯性数据的查询，并可视化了现有的依赖关系。我们基于半替代性ERC 1155令牌开发了一个组装令牌管理器，该组件令牌管理器可直接表示复杂的组装过程和结构，其中包含一个智能合约中的独特零件和批次。用户友好的前端应用程序简化了对记录的可追溯性数据的查询，并可视化了现有的依赖关系。我们基于半替代性ERC 1155令牌开发了一个组装令牌管理器，该组件令牌管理器可直接表示复杂的组装过程和结构，其中包含一个智能合约中的独特零件和批次。用户友好的前端应用程序简化了对记录的可追溯性数据的查询，并可视化了现有的依赖关系。
