Abstract In recent years, measuring instruments hav In recent years, measuring instruments have become quite complex due to the integration of embedded systems and software components and the increasing aggregation of new features. Consequently, metrological regulation and control require more efforts from notified bodies, becoming slower and more expensive. In this work, we evaluate the use of blockchains as a resource to overcome such challenges. We start with a conceptual model for implementing measuring instruments in a distributed blockchain-based architecture, and compare it with traditional measuring instruments and distributed measuring models discussed in previous works. We also made a security analysis, demonstrating that blockchains-based measuring systems can impact the way measuring instruments are used in consumer relations while improving security and simplifying metrological regulation and control. We implement a vehicle speed measuring system using the Hyperledger Fabric blockchain platform. We evaluate the security and performance of our blockchain-based measuring system by executing tests with data from real speed meter sensors. The results are promising and validate the feasibility of our idea. Finally, we point out the main challenges related to our approach, suggesting alternatives and potential issues to be addressed by future works. al issues to be addressed by future works.
