DeFi is a system which makes financial products available on a public decentralised blockchain network. These are open to use by anyone, eliminating intermediaries.

DeFi technically is software written on blockchains, enabling buyers, sellers, lenders, borrowers interaction peer-to-peer. The interaction is strictly software-based rather than institution-based.

DeFi has changed the world of finance. It is supported by blockchain technology. Therefore, the data is immutable — it cannot be changed. This makes the data easily available. DeFi is transparent, and builds trust among users.
