As part of the diploma thesis, an application has been developed that enables the generation and allocation of NFT tokens as certificates of learned knowledge, which professors send to students as proof of acquired competences. In the application, we have several levels of administrators with different permissions. A global administrator can create faculty administrator accounts, a faculty admin can create professor accounts, and a professor can generate micro-proofs in the form of NFT tokens and send them to students. Students must create their own account with their own info. When a student has collected enough tokens, they can share their collection via a link to other networks as proof of their knowledge. The application uses the Ethereum blockchain for operation, React.js framework is used for the web interface. All accounts are tied to their Ethereum key, and for additional security, two-factor authentication via e-mail account and geolocation is also used.
