DeFi is short for “decentralized finance,” and refers to an ecosystem of protocols, digital assets, smart contracts, and decentralized apps (dApps).
DeFi specifically sets out to decentralize traditional financial services using blockchain technology and provides users with open, accessible financial services such as getting a loan, lending, trading, insurance, and more.
Basically, with DeFi, you’ll be able to do the things that usually required the use of a financial services company such being able to earn interest on your savings, borrow, lend, buy insurance, trade assets, and more…all without the need for any financial services company.
