The idea is based on a system of accounting for the resources of student canteens, with the idea of ​​using the blockchain as a record of each product, leaving these accountants and available for review at any time, this would help prevent embezzlement of the products delivered, the same amount being what enters through the door in raw material, such as what is given to students as ready-made food, thus generating security to counteract corruption in this area. It is a basic system but that without a doubt could be implemented on a larger scale as it is developed and tested, as in restaurants, supermarkets or even to hospitals, all with the idea of ​​customer benefit.
