Decentralized Lending Within the Concept of a Consortium Blockchain Network

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.
