Однако мотивы, движущие инвесторами, остаются в значительной степени малоизученными. Протоколы кредитования работают по заранее заданным алгоритмам. Это упрощает автоматическое предоставление кредитов и делает DeFi-платформы доступными для пользователей публичных блокчейн-сетей. Адаптация этих алгоритмов в консорциумной блокчейн-сети в парадигме законодательства государства практически не изучена. Это обуславливает актуальность исследования. Объект исследования — кредитование в концепциях блокчейн-сети и традиционной формы; предмет — факторы, определяющие децентрализованное кредитование и их взаимосвязь с традиционными финансами. Цель исследования — предложить архитектуру модели, на основе которой могут разрабатываться децентрализованные кредитные приложения в концепции консорциумной блокчейн-сети с нативной валютой в виде цифровой валюты центрального банка (ЦВЦБ). Основные задачи исследования: 1) определить мотивы участия экономических агентов в DeFi-кредитовании, проанализировав данные о транзакциях протокола Aave. Этот протокол, работающий на блокчейне Ethereum, является одной из ведущих экосистем DeFi по рыночной капитализации и демонстрирует быстрый рост; 2) создать математическую модель и архитектуру децентрализованного кредитования для консорциумной блокчейн-сети с нативной цифровой валютой (ЦВЦБ). В основе модели будут лежать исследования DeFi-кредитования, а также аналогичные бизнес-модели из традиционной финансовой сферы. Результаты исследования представлены в виде математической модели и схемы архитектуры модели децентрализованного кредитования в концепции консорциумной блокчейн-сети с нативной валютой в виде ЦВЦБ.</p></abstract><trans-abstract xml:lang="en"><p>The decentralized finance (DeFi) ecosystem is a complex and ever-evolving system composed of various protocols. One of these protocols is lending, which has seen significant growth in recent times. However, the motivations behind investors’ interest in this area remain largely unknown. Lending protocols operate on predefined algorithms that automatically provide loans to users, allowing them to actively participate in DeFi lending platforms on public blockchain networks. The adaptation of these algorithms to a blockchain network within the framework of state legislation has not been explored in depth. This determines the importance of the study. The object of the study is to compare lending in a blockchain network with traditional forms; the subject is to identify the factors that influence decentralized lending and its relationship with traditional finance. The aim of this study is to develop a model architecture that can be used to create decentralized credit applications within a consortium blockchain network that uses a native currency, such as a central bank digital currency (CBDC). The main objectives of this study are:1) using data on transactions from the Aave lending protocol, one of the leading decentralized finance (DeFi) ecosystems in terms of market capitalization, to identify the motivations that drive participants to engage in DeFi lending activities; 2) based on research into the DeFi token ecosystem and its market, as well as analogues of traditional financial lending models, to develop a mathematical model and an architectural diagram for a decentralized lending system built on a consortium blockchain with a Central Bank Digital Currency (CBDC) as the native currency. The results of the study are presented in the form of a mathematical model and a diagram of the architecture for a decentralized lending system based on a consortium blockchain network using a consortium with a native cryptocurrency, known as CBDC.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кредитование</kwd><kwd>залоговое кредитование</kwd><kwd>ликвидация</kwd><kwd>децентрализованные финансы</kwd><kwd>автоматизированный алгоритм</kwd><kwd>розничный ЦВЦБ</kwd><kwd>консорциумная блокчейн-сеть</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Lending</kwd><kwd>collateralized borrowing</kwd><kwd>liquidations</kwd><kwd>decentralized finance</kwd><kwd>automated algorithm</kwd><kwd>retail CBDC</kwd><kwd>consortium blockchain network</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">Heimbach L., Huang W.
