Decentralized Finance, or DeFi, is described as a “composable ecosystem of protocols built on Ethereum that enable the creation of financial applications”. In other words, it is a financial system that runs on a decentralized infrastructure.
With DeFi, you can do everything that you can do with traditional financial products, but without the need for a central authority or intermediaries.
DeFi applications allow users to earn, borrow, lend, trade, and much more without the need for a third party and at a faster pace compared to banks.
Some popular DeFi protocols are MakerDAO, which allows users to create and manage digital collateral-backed loans, and Compound, which allows users to earn interest on their cryptocurrency holdings.
Another important aspect of DeFi is flash loans. A flash loan is a type of loan that is instantly available and does not require collateral. The loan is given and repaid in the same transaction.
Because the loan is given and repaid in the same transaction, there is no need for a third party to hold or manage the loan.
Flash Loans are unique in their own way for the fact that a user doesn’t need to provide collateral or qualify for a credit check. Anyone can just ask the lenders whether they could borrow $100,000 worth of Ether. And if their loan is approved, they can withdraw those funds, use them as leverage and return back the amount.
The use of flash loans has increased in recent months as it allows for the creation of complex financial products and protocols.
Decentralized finance is one of the most important aspects of a decentralized economy.
