DeFi (Decentralized Finance)


DeFi is an integral part of the modern crypto economy. They are analogous to the traditional banking sector. The abbreviation DeFi stands for Decentralized Finance. This concept refers to a set of various services, tools, and applications. They are based on the blockchain and are aimed at performing various functions related to the cryptocurrency world. DeFi exchange aims to help traders carry out various transactions for the sale and purchase of cryptocurrencies to make a profit.

What is DeFi in cryptocurrency in simple terms

DeFi is a kind of space. It consists of financial protocols and applications. They work based on smart contracts and are built on a blockchain. Most projects have launched and built their services on Ethereum, but other blockchain networks are also gaining momentum as platforms for new projects. In simple words, we can say that DeFi is an analog of banking services that are offered to work with crypto assets. The main difference lies in a wider set of tools.

A smart contract is a virtual contract and a computer program. Its conditions are prescribed by both parties to the transaction, and the execution is carried out automatically. Smart contracts contribute to the automation of projects, companies and decentralized applications. They can be the basis for:

  • credit deal;
  • trading on the stock exchange;
  • ordinary purchase in the online store;
  • other options.

Smart contracts are involved in the successful operation of the DAO. Smart contacts are already beginning to be used in the legal and real estate industries.

When did DeFi appear?

The launch of Ethereum opened up smart contracts to the world of cryptocurrencies, which were written using programming. Ethereum has become the backbone of DeFi. This event gave rise to decentralized finance as a separate sector.
