Традиционные модели блокчейна часто страдают от таких ограничений как большая задержка, ограниченная пропускная способность и перегрузка сети, особенно при больших объемах транзакций. Предлагается новая двухслойная архитектура блокчейна, разработанная для устранения этих ограничений путем разделения обработки транзакций и механизмов консенсуса на два отдельных, но совместимых уровня. Первый уровень (облегченный транзакционный уровень) обеспечивает обмен данными и их верификацию в режиме реального времени с минимальными вычислительными затратами. Второй уровень фокусируется на надежном консенсусе, безопасности и долгосрочной неизменности данных. Разделяя эти функции, предлагаемая архитектура значительно улучшает масштабируемость, снижает задержку и повышает отзывчивость системы. Экспериментальное моделирование показало, что двухслойный подход превосходит традиционные одноцепочечные системы с точки зрения пропускной способности транзакций, времени подтверждения и масштабируемости при изменяющихся нагрузках. Предложенная архитектура обладает большими возможностями для внедрения в секторах, требующих высокопроизводительных, безопасных и децентрализованных транзакционных систем, таких как финансы, цепочки поставок и экосистемы интеллектуальных отраслей.</p></abstract><trans-abstract xml:lang="en"><p>In the era of rapidly evolving digital infrastructures, ensuring the scalability and efficiency of technological transactions has become a critical challenge. Traditional blockchain models often suffer from limitations, such as high latency, restricted throughput, and network congestion, particularly under high transaction volumes. This paper proposes a novel dual-layer blockchain architecture designed to address these limitations by segregating transaction processing and consensus mechanisms into two distinct but interoperable layers. The first layer, a lightweight transactional layer, handles real-time data exchange and verification with minimal computational overhead, while the second layer focuses on robust consensus, security, and long-term data immutability. By decoupling these functions, the proposed model significantly improves scalability, reduces latency, and enhances system responsiveness. Experimental simulations demonstrate that the dual-layer approach outperforms conventional single-chain systems in terms of transaction throughput, confirmation time, and scalability under varying loads. This architecture holds promising potential for deployment in sectors requiring high-performance, secure, and decentralized transaction systems, such as finance, supply chain, and smart industry ecosystems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>блокчейн</kwd><kwd>безопасность</kwd><kwd>кожевенная промышленность</kwd><kwd>цепочки поставок</kwd></kwd-group><kwd-group xml:lang="en"><kwd>blockchain</kwd><kwd>security</kwd><kwd>leather industry</kwd><kwd>supply chain</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность женскому колледжу Марудхар Кесари Джайн (автономному), Ваниямбади-635751, Тамил Наду, за предоставление доступа к вычислительным мощностям Лаборатории инструментов FIST, поддержанному грантом № SR/FST/COLLEGE/2023/1511 (Программа FIST-2023, TPN‑88688).</funding-statement><funding-statement xml:lang="en">The authors would like to acknowledge Marudhar Kesari Jain College for Women (Autonomous), Vaniyambadi-635751, Tamil Nadu, for providing access to the computational facilities in the FIST Instrumentation Lab, supported under Grant No. SR/FST/COLLEGE/2023/1511 (FIST Program-2023, TPN-88688).</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">Angelis J., da Silva E.R.
