Defi is one of the very important applications of web3


Centralized Finance

In centralized finance, money is held by banks and third parties who facilitate money movement between parties, with each charging fees for using their services. A credit card charge starts from the merchant and moves to an acquiring bank, which forwards the card details to the credit card network.


The network clears the charge and requests a payment from the bank. Each entity in the chain receives payment for its services, generally because merchants must pay for the use of credit and debit cards.



All financial transactions are overseen in centralized finance, from loan applications to a local bank's services.


Decentralized Finance

Decentralized finance eliminates intermediaries by allowing people, merchants, and businesses to conduct financial transactions through emerging technology. Through peer-to-peer financial networks, DeFi uses security protocols, connectivity, software, and hardware advancements.



Wherever there is an internet connection, individuals can lend, trade, and borrow using software that records and verifies financial actions in distributed financial databases. A distributed database is accessible across various locations as it collects and aggregates data from all users and uses a consensus mechanism to verify it.



Decentralized finance eliminates the need for a centralized finance model by enabling anyone to use financial services anywhere regardless of who or where they are. DeFi applications give users more control over their money through personal wallets and trading services that cater to individuals.


A great reason to learn Defi is that some apps have an APY (Annual Percentage Yield) of 10-20%, compared to the traditional 0.01% return for banks. Think about it - the return on your money could one day scale up to 2000x!
