Для достижения поставленной цели в статье последовательно рассмотрены следующие вопросы: анализ технических возможностей блокчейн, анализ алгоритмов обработки заявлений на государственном портале, исследование технологической особенности развертывания сети блокчейн для повышения эффективности предоставления услуг, разработка аналитических соотношений для исследования зависимости времени обработки, разработка имитационной модели для исследования вероятностных характеристик времени обработки. В статье предложена модель применения технологии блокчейн в государственных информационных системах, например, на портале государственных услуг, с учетом большого числа органов власти, участвующих в процессе. </p></abstract><trans-abstract xml:lang="en"><p>The purpose of the article is to study and model certain aspects (methods, algorithms for processing applications) of introducing blockchain technology into individual elements of state information systems. To achieve this goal, the following issues are sequentially considered in the article: analysis of the technical capabilities of blockchain, analysis of algorithms for processing applications on the state portal, study of the technological features of deploying a blockchain network to improve the efficiency of service provision, development of analytical relationships for studying the dependence of processing time, development of a simulation model for research processing time probabilistic characteristics. The article proposes a model for the application of blockchain technology in public information systems, for example, on the portal of public services, taking into account the large number of authorities involved in the process.  </p></trans-abstract><kwd-group xml:lang="ru"><kwd>блокчейн</kwd><kwd>государственные информационные системы</kwd><kwd>портал госуслуг</kwd><kwd>аутентификация услуг</kwd><kwd>сетевые харакетристики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>blockchain</kwd><kwd>government information systems</kwd><kwd>public services portal</kwd><kwd>service authentication</kwd><kwd>network characteristics</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Госуслуги.
