Digital Twins are software technologies that enable the modelling of real-world phenomena in digitised environments, representing and monitoring the reality of various processes, including IoT deployments. Since 2017, the use of Digital Twins has been increasing. However, in the road transport and logistics realm, the adoption rate remains low, primarily due to the costs of processing and validating data in centralised scenarios, among other factors. On the other hand, Blockchain technologies were created to provide immutable and decentralised data storage in diverse scenarios, adding a layer of isolation and reliability in heterogeneous solutions. This paper presents a case study proposing a Digital Twin based on open-source Blockchain technologies, such as FIWARE Canis Major. The primary goal is to design and implement a robust and efficient open-source architecture that allows for the control and optimisation of vehicle fleet allocations in logistics/transport companies within supply chain management. This case study aims to showcase the practical application of the proposed solution in a real-world context, providing insights into its eco-friendly and low-cost attributes while opening the door to a large number of additional applications.

用于物流和运输物联网部署的基于区块链的数字孪生

数字孪生是一种软件技术，可以在数字化环境中对现实世界现象进行建模，代表和监控各种流程的现实，包括物联网部署。自2017年以来，数字孪生的使用不断增加。然而，在道路运输和物流领域，采用率仍然很低，主要是由于集中场景中处理和验证数据的成本等因素。另一方面，区块链技术的创建是为了在不同的场景中提供不可变和去中心化的数据存储，为异构解决方案增加一层隔离和可靠性。本文提出了一个案例研究，提出基于开源区块链技术的数字孪生，例如 FIWARE Canis Major。主要目标是设计和实施一个强大而高效的开源架构，允许在供应链管理中控制和优化物流/运输公司的车队分配。本案例研究旨在展示所提出的解决方案在现实世界中的实际应用，深入了解其环保和低成本属性，同时为大量其他应用打开大门。
