On-line samovzdělávací platforma pro programování s následnou certifikací pomocí blockchainu

The challenge of issuing qualification certificates is one of the key aspects of the modern educational process, with growing demands for transparency, security, and reliability. This trend is closely linked to the development of online education, which offers flexibility and broad availability of learning materials. Despite these advantages, existing e-learning platforms face several challenges. These include the vulnerability of centralized systems to attacks, the time and financial demands of certificate verification, and the risk of loss or unauthorized modifications of certificates. This bachelor thesis focuses on the design and implementation of an educational platform that utilizes blockchain technology to achieve these goals. The research includes an analysis of existing online educational platforms to identify their key features and problematic aspects. Based on the findings, a development methodology for the new platform is formulated, functional and non-functional requirements are defined, the application architecture is designed, and appropriate technologies for implementation are selected. The thesis also includes an analysis of various blockchain architectures, leading to the selection of a blockchain that meets the defined requirements. The functionality and compliance of the implemented platform with the stated requirements are verified through acceptance testing. The main contribution of this work is the creation of an online educational platform focused on programming education, which facilitates the issuance of certificates using blockchain. These certificates are represented as smart contracts, automating the issuance and verification processes without the need for a central authority. The thesis also proposes a concept for the further development of this technology in the field of education.
