    Recent developments in Polish legislation concerning the healthiness of products in schools shops and results of law compliance verification resulted in a need for a way to supervise purchases in school shops. In this article, a solution for this problem is presented in a form of an online payment platform utilizing virtual currency called eZloty. The platform is based on blockchain technology which allows storing transaction history in an immutable form. As a result, eZloty payment system would enable supervision of products bought in schools, thus creating a possibility for more directed actions promoting healthy food and compliance with ministry regulations.
