Background/purpose. This research was conducted to address the growing need for more secure, transparent, and efficient solutions for the issuance and management of university degrees. The main purpose of the study is to evaluate which Blockchains are best suited for this application, aiming to enhance the reliability and speed of degree-related transactions. Materials/methods. The study is based on a comparative evaluation of several leading Blockchains (Ethereum, Polygon, Cardano, Stellar, and EOS), using criteria such as scalability, security, ease of implementation, transaction speed, and associated costs. Results. The results show that Stellar is the best-suited Blockchain for managing degrees, due to its very low transaction fees and high speed. EOS ranks second, offering low fees but requiring more complex resource management. Ethereum has higher transaction costs, while Polygon and Cardano offer a balanced mix of cost and performance. Conclusion. The main conclusion of the study is that Stellar is the most appropriate option for university degree management. However, the final choice should be based on the specific needs of each institution.
