What is Decentralised finance or DeFi

Decentralised finance, or “DeFi” is a rapidly growing movement in the world of cryptocurrency and blockchain technology. It is a new way of thinking about financial systems, built on the principles of transparency, security, and decentralisation.

At its core, DeFi is a set of financial applications and protocols that run on a blockchain, such as Ethereum. These applications and protocols are built to be open-source, meaning anyone can access and use them. They also operate in a decentralised manner, meaning they are not controlled by a single entity or organisation.




One of the most important aspects of DeFi is the use of smart contracts. A smart contract is a self-executing contract with the terms of the agreement written directly into code. This allows for transparent and trustless interactions between parties, as the terms of the contract are automatically enforced by the blockchain.

DeFi applications can be divided into several categories, each with its own specific use case.

Lending and borrowing platforms allow users to lend and borrow assets, such as cryptocurrencies, using smart contracts. These platforms typically use collateral to ensure the safety of the loans. Examples of lending and borrowing platforms include Aave, Compound, and MakerDAO.

Decentralized exchanges (DEXs) are blockchain-based exchanges that allow users to trade assets in a decentralized manner. This means that users have full control over their assets and do not have to rely on a centralized intermediary to handle their trades. Examples of DEXs include Uniswap and Kyber Network.

Stablecoins are cryptocurrencies that are pegged to the value of a traditional asset, such as the US dollar. This allows for more stable prices and less volatility, making them useful for lending and borrowing, as well as for trading. Examples of stablecoins include DAI, USDC, and TUSD.

Insurance protocols provide decentralised insurance coverage for assets on the blockchain. These protocols use smart contracts to automatically pay out claims in the event of a loss. Examples of insurance protocols include Nexus Mutual and Cover Protocol.

Another important aspect of DeFi is the use of yield farming, also known as liquidity mining. This is a process where users can provide liquidity to a decentralised exchange, and in return, they receive rewards in the form of tokens. These tokens can then be traded or used to access other DeFi services.

DeFi has the potential to revolutionise the way we think about finance and monetary systems. It allows for more transparency, security, and decentralisation, while also providing new opportunities for earning yield and accessing financial services.

However, it’s important to note that DeFi is still in its early stages, and there are risks associated with using these platforms. These risks include smart contract bugs, hacking, and regulatory uncertainty. It’s important for users to thoroughly research and understand the platforms they use, and to only invest what they can afford to lose.

In conclusion, DeFi is a new and exciting movement in the world of cryptocurrency and blockchain technology. It aims to create a more transparent, secure, and decentralised financial system. While there are risks associated with DeFi, it has the potential to revolutionise the way we think about and access financial services. As the DeFi industry continues to evolve and mature, it will be interesting to see how it will shape the future of finance.
