Decentralized E-Voting on Solana Blockchain
Hošala, Martin ; Očenášek, Pavel (oponent) ; Homoliak, Ivan (vedoucí práce)
This work was aimed at finding out the suitability of Solana blockchain for BBB-Voting system and creating a prototype of this system based on the provided solutions on Ethereum. The problem with Ethereum is its performace - a larger voting would take weeks. Solana promises much higher performace. To create the final solution, it was necessary to analyze Solana's system, BBB-Voting, design BBB-Voting for Solana, implement and test it. The final prototype is implemented in Rust using the Anchor framework. During the development, it was found that the algorithm which within the BBB-Voting protocol is used for vote validation is too computationally intensive and therefore due to the current limit on Solana, the system cannot be deployed on the mainnet. However, it is expected that this limit will be changed and the system can be deployed in the future. In that case, a rough estimate of the speedup over Etherem counterparts is around 3000 %. The cost of voting on Solana is also an order of magnitude lower. As part of the work, a front-end for voting was also developed - a single-page web application built using ReactJS.

Analysis of the Move Programming Language for Blockchain Platforms
Šmehýl, Adam ; Homoliak, Ivan (oponent) ; Perešíni, Martin (vedoucí práce)
This thesis studies the Move programming language, focusing on its usability for developing applications (smart contracts or programs) on blockchain platforms. Two key aspects are considered: first, a comparison of programming models using Move to widely used models of EVM-compatible platforms like Ethereum and the popular Solana blockchain; and second, the implementation of the same program in Solidity on Ethereum, Rust on Solana, and Move on Aptos. Criteria for comparison include deployment and execution costs, processing speed, code readability, and overall development experience. A detailed analysis of Move's unique features, such as resource management, the use of generics, and other security enhancements in programming, is conducted. The results demonstrate Move's potential for extensive use in the blockchain field, with its strong emphasis on secure coding and resource management contributing to the growing interest within the blockchain community.

Využití technologie blockchain ve firmách
KNĚŽÍČKOVÁ, Kristýna
Tato bakalářská práce se zabývá technologii blockchain a jeho využitím ve firmách. Očekávají se významné dopady zejména na obchodní modely organizací v sektorech služeb. Hlavním cílem bylo zjištění faktorů, které ovlivňují zavedení blockchainu. Ke zjištění těchto faktorů byl použit sestavený dotazník a pomocí modelu TOE byly faktory rozděleny do příslušných oblastí modelu. První část práce se zabývá popisem příslušných technologií, jedná se zejména o popis technologie a principů blockchainu a jeho užití. V praktické části pak navrhujeme model pro hodnocení faktorů ovlivňujících přijetí této technologie v organizacích.
