Uma arquitetura para sistemas de rastreabilidade em cadeias logísticas usando Blockchain

Abstract

Traceability is essential to ensure the quality and safety of products, from manufacturing and processing to the final consumer. This monitoring of the supply chain from beginning to end constitutes a major logistical challenge, as the agents involved in each stage of the chain are often independent of each other, making the verification and auditing process between the parties more bureaucratic and complex. In this context, the main objective of this work is to propose an architecture for the traceability of logistic chains using Blockchain technology in order to show that this architecture can solve many of the problems of logistic chains and also that it can serve as a basis for the development of other more complex and specific solutions of the same type. We selected the Hyperledger Fabric blockchain network by comparing Ethereum and Hyperledger. We used concepts of virtualization using containers and Docker for the simulations of the experiments. We conducted tests to show the correct functioning of the architecture developed. From creating a small-scale model with Docker containers to validating the implementation of the network and the execution of the smart contract, with the correct registration of information in the blockchain, as well as its correct reading. The results of these tests demonstrated the viability of the architecture on a small scale, thus validating the basic principles that also allow its operation on a large scale. Based on our tests, we concluded that the presented solution is viable, fulfilling the initially proposed objectives.
