## What Is Decentralized Finance (DeFi)?

Through "smart contracts," which are merely pieces of code that are deployed and executed on the blockchain, peer-to-peer value transactions can now be programmatically executed based on a set of conditions, thanks to the emergence of public blockchain networks like Ethereum. Decentralized applications, or "dapps," are applications created using smart contracts. They are a primary driving force behind the growing interest in using bitcoin, or digital currency, in industry. In practice, DeFi services are dapps that use the strength of smart contracts and the public blockchain's decentralized nature to offer globally accessible financial services.

Decentralized finance, also known as "DeFi," refers to the shift away from traditional, centralized financial systems and toward peer-to-peer financing enabled by decentralized technology based on the Ethereum blockchain.
DeFi technology generates decentralized money and does away with the need for central banks under the power of the government to produce and manage the currency. But DeFi technology can also offer a wide range of additional blockchain-based financial services applications. DeFi technology is used by fintech businesses to provide insurance, stock trading, savings accounts, and loans, among other services.
DeFi does away with the usage fees that banks and other financial institutions impose. Anyone with an internet connection can use DeFi, and users can store money in a safe digital wallet and transfer money quickly.

## Centralized Finance vs. Decentralized Finance (DeFi)

**Centralized Finance**
In centralized finance, banks and other third parties hold the funds and enable the transfer of funds between parties; each party charges a fee for its use. An acquiring bank receives the card information from the merchant and passes it on to the credit card network to complete the credit card transaction.
The network authorizes the charge and asks the bank for payment. Because retailers typically have to pay for the usage of credit and debit cards, each link in the chain is paid for the services it provides.
CeFi is limited by banking hours for particular actions, and transactions can be cumbersome, requiring settlement times on the back end.
Centralized finance oversees all financial activities, including loan applications and local bank services.

**Decentralized Finance**
DeFi is a market segment that offers financial services and products that are available to anybody with an internet connection and run independently from banks or other third-party businesses. Since the decentralized financial market is always active, transactions happen in close to real-time and cannot be stopped by an intermediary. Your cryptocurrency is available for storage anywhere, including on computers, in hardware wallets, and in other locations.
By enabling individuals, businesses, and merchants to perform financial transactions through new technologies, decentralized finance eliminates middlemen. DeFi makes use of the connection, software, hardware, security protocols, and peer-to-peer financial networks.
People can lend, trade, and borrow using software that logs and validates financial transactions in distributed financial databases from anywhere there is an internet connection. A distributed database collects and aggregates data from all users and utilizes a consensus process to verify it, making it available from different locations.
By enabling anyone to use financial services wherever they are, regardless of who they are or where they are located, decentralized finance eliminates the need for a centralized finance model. Through individual-focused trading services and personal wallets, DeFi applications give users more control over their finances.

## How Does DeFi Work?

DeFi goes beyond the generation of new digital money or value, even though it is commonly addressed about cryptocurrencies. The purpose of DeFi's smart contracts is to replace conventional financial systems.
The blockchain technology that cryptocurrencies employ is used in decentralized finance. A distributed and secure database or ledger is referred to as a blockchain. The blockchain is operated and transactions are handled by programs known as dApps.
Some of the ways people are engaging with DeFi today: 
**1. Lending:** Earn interest and rewards for lending out your cryptocurrency every minute, rather than just once a month.![Lending](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/i1046kxpfcyazylyz2je.jpg)

**2. Getting a loan:** Instantly apply for a loan without having to fill out any paperwork, even the incredibly brief "flash loans" that conventional financial institutions do not provide.![Getting a loan](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/os3yszn9mdfosvv5g4pf.jpg)

**3. Trading:** Make peer-to-peer cryptocurrency trades, just like you would if you were buying and selling securities without using a broker.![Trading](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/3hldv4ol1xnrgsc6prxg.jpg)

**4. Saving for the future:** Put a portion of your cryptocurrency into an alternative to a savings account to earn higher interest rates than you would ordinarily receive from a bank.![Saving for the future](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/7wxw8hlodeygal2f8ht5.jpg)

**5. derivatives:** Invest in specific assets, long or short. Consider them the cryptocurrency equivalent of stock options or futures contracts.![Buying derivatives](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/q1ws30d8xo7z6eme0r1j.jpg)

## Is DeFi safe?

DeFi technology is relatively new, thus unanticipated negative effects are possible. Because startup failure is so common, new businesses that use DeFi technology run the risk of failing, and programming mistakes might give hackers access to lucrative systems. Your money could be completely lost if you invest in or store money with a DeFi enterprise that fails.
While DeFi platforms typically don't offer any method of recovering lost money, deposits with traditional, centralized financial institutions are covered by the Federal Deposit Insurance Corporation (FDIC). If a regular financial transaction goes wrong, a customer can register a complaint with the Consumer Financial Protection Bureau (CFPB), but if you fall victim to a fraudulent DeFi transaction, there is no such recourse available. 
It's interesting to note that a different kind of DeFi program is becoming accessible to overcome these shortcomings. Those looking for a way to safeguard themselves against losses from other smart contracts are being offered decentralized insurance, which is produced by individuals pooling their money as collateral. The premiums paid by those who are insured are collected by the individuals who contribute to the bitcoin pools.

## What are the downsides DeFi?

1. Active trading can become expensive due to the Ethereum blockchain's fluctuating transaction rates.
2. Given that this is a new technology, your investment may experience high volatility depending on the dapps you use and how you use them.
3. For tax purposes, you must keep your own records. Regional differences in regulations are possible.
