Decentralized Finance Defined
Decentralized Finance (DeFi) refers to the financial transactions that eradicate intermediaries between participants. It uses cryptocurrency and blockchain technology to eliminate central authorities and provide peer-to-peer facilities to carry out financial services such as banking, loans, mortgages, and more. The primary purpose here is to establish an open-source, transparent, and permissionless ecosystem without any central authority owning the power over financial transactions. It allows participants to control their assets, efficiently conduct peer-to-peer exchanges and build decentralized applications (dApps).
Once a transaction is carried out in a traditional banking system, its details are recorded in a private ledger owned and monitored by a financial institution. However, in DeFi, the financial transactions are stored in a computer code on a decentralized public ledger. All participants using DeFi applications and platforms have an identical copy of the general ledger.
This ledger holds the information of every transaction in encryption code. Since decentralized blockchain platforms and applications are immutable, the records of ownership cannot be modified or deleted by a third party providing security in verifying transactions and storing their data.
Decentralized Finance works on the traditional financial system and replaces the intermediaries or central authorities with smart contracts. A smart contract is an automated merger, enforces agreements without intermediary involvement, and is easily accessible by anyone with an established internet connection. Most of the protocols work on the Ethereum blockchain, and the decentralized applications are often created using Ethereum.
