This work aimed to develop an application that can generate identifiers for cheese and through a Blockchain network to validate such information. For this, a study was carried out on the functioning of a Blockchain and its characteristics of security, immutability, and scalability. The possibility of using Blockchain in the traceability of food products was identified. With this, the modeling and implementation of a system for recording data about cheeses and their manufacturers in a Blockchain were carried out. Such registration allows us to validate the information and make it available to consumers through the QRQuejio mobile application and to verify the authenticity of the data, through reading in the system database and the Blockchain, thus confirming the authenticity of the records.
