Research background: Its simplest form, decentralized finance is a system by which financial products become available on a public decentralized blockchain network, making them open to anyone to use, rather than going through middlemen like banks or brokerages. Unlike a bank or brokerage account, a government-issued ID, Social Security number, or proof of address are not necessary to use DeFi.
Purpose of the article: The aim of the contribution is more specifically, DeFi refers to a system by which software written on blockchains makes it possible for buyers, sellers, lenders, and borrowers to interact peer to peer or with a strictly software-based middleman rather than a company or institution facilitating a transaction.
Methods: Multiple technologies and protocols are used to achieve the goal of decentralization. For example, a decentralized system can consist of a mix of open-source technologies, blockchain, and proprietary software. Smart contracts that automate agreement terms between buyers and sellers or lenders and borrowers make these financial products possible. Regardless of the technology or platform used, DeFi systems are designed to remove intermediaries between transacting parties.
Findings & Value added: The article provides an overview of decentralized finance (DeFi) solutions that have already proved they are better alternatives to traditional finance. With DeFi, users can take advantage of lower transaction rates, higher interest rates or an opportunity to diversify investments.
