Various electronic voting systems have been developed. But most of such systems have such disadvantages as lack of transparency and the possibility to check the correctness of vote counting. The article considers the development of voting systems using blockchain technology. It shows the possibility of increasing transparency, security and reliability of electoral processes on the basic of blockchain technology, especially in conditions of limited recources. The practical implementation developed by the authors is shown - an electronic voting system based on blockchain technology using smart contracts in the Solidity language and a user interface in Python with the Web3.py library. An analysis of existing solutions is carried out, their disadvantages are identified, the system architecture is proposed and the main functions are implemented: registration of candidates, voting, protection against duplicate votes and automatic counting of results. The results of testing in the Ganache environment confirmed the correctness of the system and its resistance to external influences. In comparison with analogs, the design of the system proposed by the authors using blockchain technology is simple, accessible and highly reliable, which makes it promising for implementation. The study of the evolution of electronic voting systems, the use of blockchain technology for electronic voting systems contribute to the development of effective solutions for democratic governance.
