Настоящая статья посвящена методологии и практическому применению инструмента бизнес-аналитики Power BI для анализа и визуализации данных, генерируемых этой системой. Использование инструментов бизнесаналитики, таких как Power BI, для анализа данных из блокчейн-систем голосования является важным шагом для валидации их производительности, безопасности и прозрачности. Блокчейн представляет собой децентрализованный цифровой реестр, состоящий из хронологически упорядоченной цепочки блоков. В контексте электронного голосования эти блоки содержат транзакции, которые могут представлять собой различные операции: регистрация избирателей и кандидатов, подача голосов, подсчет результатов.Ключевые характеристики данных в блокчейне, делающие их подходящими для систем голосования и последующего анализа, включают: неизменность (Immutability), прозрачность (Transparency), децентрализация (Decentralization), отслеживаемость (Traceability). Каждая транзакция имеет уникальный идентификатор и временную метку, что позволяет отслеживать все операции в системе.Работа демонстрирует, как Power BI позволяет трансформировать сложные и распределенные данные блокчейна в наглядные и легко интерпретируемые графики и дашборды, что критически важно для оценки производительности, безопасности и прозрачности системы голосования. Представлены ключевые метрики и визуализации, а также описан процесс интеграции данных блокчейна с аналитическим инструментом. Полученные результаты подтверждают, что использование Power BI является эффективным подходом для валидации и демонстрации преимуществ децентрализованных систем.</p></abstract><trans-abstract xml:lang="en"><p>As part of the research work (IRN AP23489791), an online voting system based on blockchain technology was developed and implemented. This article is devoted to the methodology and practical application of the Power BI business intelligence tool for analyzing and visualizing data generated by this system. Using business intelligence tools such as Power BI to analyze data from blockchain voting systems is an important step to validate their performance, security, and transparency. The blockchain is a decentralized digital registry consisting of a chronologically ordered chain of blocks. In the context of electronic voting, these blocks contain transactions that can represent various operations: registration of voters and candidates, submission of votes, and counting of results.The key characteristics of the data in the blockchain that make them suitable for voting systems and subsequent analysis include: Immutability, transparency, decentralization, Traceability. Each transaction has a unique identifier and a timestamp, which allows you to track all transactions in the system.The work demonstrates how Power BI enables the transformation of complex and distributed blockchain data into visual and easily interpretable graphs and dashboards, which is critical for evaluating the performance, security and transparency of the voting system. Key metrics and visualizations are presented, and the process of integrating blockchain data with an analytical tool is described. The results confirm that using Power BI is an effective approach for validating and demonstrating the benefits of decentralized systems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>блокчейн</kwd><kwd>онлайн-голосование</kwd><kwd>Power BI</kwd><kwd>бизнес-аналитика</kwd><kwd>визуализация данных</kwd><kwd>безопасность</kwd><kwd>прозрачность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>blockchain</kwd><kwd>online voting</kwd><kwd>Power BI</kwd><kwd>business analytics</kwd><kwd>data visualization</kwd><kwd>security</kwd><kwd>transparency</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследовательская работа проводится в рамках ГФ Министерства науки и высшего образования Республики Казахстан AP23489791 «Разработка системы онлайнголосования на основе технологии блокчейн» на 2024-2026 годы.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">DVTChain: A blockchain-based decentralized mechanism to ensure the security of digital voting system voting system / Syada Tasmia Alvi et al // Journal of King Saud University – Computer and Information Sciences. – 2022. – vol. 34(9). https://doi.org/10.1016/j.jksuci.2022.06.014.</mixed-citation><mixed-citation xml:lang="en">DVTChain: A blockchain-based decentralized mechanism to ensure the security of digital voting system voting system / Syada Tasmia Alvi et al // Journal of King Saud University – Computer and Information Sciences. – 2022. – vol. 34(9). https://doi.org/10.1016/j.jksuci.2022.06.014.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Lakshmi Sai Priya K.
