Diseño y simulación de un sistema de adquisición de datos y tracking del proceso productivo de café : Sistema de tracking basado en Blockchain del proceso productivo del café.

Abstract

In this capstone project, the application of blockchain technology is presented as an alternative for the registration and storage of information in a decentralized fashion, for the design and simulation of a traceability system for the agricultural supply chain of specialty coffee. A supply chain with a linear flow was considered, with the coffee batch as the traceable resource unit (TRU). Smart contracts register information about the different intervention stages throughout the value chain of a specific coffee batch, as well as information about users who execute transformation processes. Smart contracts also allow the reading of the registered data in the system to be shown to users. The smart contracts were coded in Solidity language and deployed on a Rinkeby testnet. User interaction with smart contracts hosted on the blockchain was based on a web application called CoffeeTrack. This allows users to log in through their MetaMask digital wallet account and access their dashboard to register information for a specific coffee batch. The web application also provides a section aimed at consumers, which allows them to scan the QR code on the cover of their coffee to find out its origin and traceability data throughout the value chain.
