Crypto money like BITCOIN (BTC) and altcoins like CARDANO (ADA) , ETHEREUM (ETH) and many other coins have grown into a trillion-dollars business, causing a wave of financial disruption around the world.

Decentralized Finance (also known as DeFi) is a blockchain-based type of finance that does not rely on central financial intermediaries such as brokerages, exchanges, or other financial institutions.DeFi refers to financial apps built on blockchain technologies, generally employing smart contracts, and is inspired by blockchain technology. Smart contracts are enforceable agreements that are automated and can be accessed by anyone with an internet connection. They do not require any intermediaries to execute and can be accessed by anyone with an internet connection.

Through the improvement of distributed ledger technologies, we are witnessing a quantum jump in the new functionality of money. For the first time in record, the papulation of the world are shaping a global financial system. AnyOnecan take part in DeFi protocol governance and have a seat at the table where the world of decentralised finance is actively constructed.

DeFi has grown in popularity in recent years and is now one of the most disruptive blockchain technologies available. Cryptocurrencies hit unprecedented heights in 2021, businesses actively adopt crypto payments, and miners go all-in on graphic cards to boost profitability. Despite the fact that digital currency price charts have recently resembled a roller coaster, the niche is actively progressing and offering new vistas.

DeFi is one of the bitcoin ecosystem's most rapidly growing subsectors. For more than a year, Ethereum-based finance platforms have been gaining traction. The DeFi industry has grown 65 times since May 2020, with a total value locked (TVL) of $65,2 billion. In September 2020, Uniswap, a decentralised financial marketplace, issued its UNI token at a price of $0,48 per token. A year later, its price had risen to $22,08 per token, and Uniswap had established itself as a well-known DeFi exchange. So my cryptoacademy friends this is DeFi revolution.

💠 What is the mechanism behind it?

Users link with DeFi through software known as dapps ("decentralised apps"), the majority of which are now based on the Ethereum blockchain. There is no need give an application or open an account, unlike a traditional bank.
Here are some ways that people are connecting with DeFi:

🔷️ LENDING:-
Earn money and benefits every minute, not just once a month, by lending out your cryptocurrency.

🔷️ ObtaininG A LOAN:-
Instantly get a loan without having to fill out paperwork, even for extremely short-term "flash loans" that traditional financial institutions don't give.

🔷️ TRADING:-
Make peer-to-peer crypto asset trades, just like you could buy and sell stocks without using a stockbroker.

🔷️ INVEST IN THE FUTURE:-
Put part of your cryptocurrency into alternative savings accounts to achieve better interest rates than you'd get from a bank.

🔷️ INVESTING IN DERIVATIVES:-
Place long and short bets on certain assets. Examine them the cryptocurrency equivalent of stock options or futures contracts.

💠 Explain the benefits of DeFi products to crypto users.

🔶️ IMMUTABILITY:-
Blockchain has achieved true immutability thanks to the effective use of cryptography and consensus techniques such as proof-of-work.The genuine benefits of immutability in finance have been enabled by decentralised finance.It is virtually impossible to modify any record on the blockchain network thanks to immutability.

Immutability, in addition to the benefits of decentralisation, provides a promising assurance of security. Unexpectedly, the blockchain immutability features protaction the integrity of DeFi systems when conducting financial transactions.

🔶️ PERMISSIONLESS:-
The term "decentralised" is the first and most important aspect that determines the identity of decentralised finance.One of the fundamental ideas of blockchain is decentralisation, which helps to reduce reliance on businesses.

By ensuring that individual transaction histories can be easily disseminated among all users, blockchain networks are successful in achieving all of these qualities.Ethereum is the second-largest blockchain system, and it is highly decentralised due to its permissionless nature.The permissionless characteristics of blockchain in DeFi applications could benefit from blockchain as well. Ethereum is a popular network for smart contract development, and it's a solid choice for constructing DeFi applications.

🔶️ TRANSPARENCY:-
Transparency is one of the prominent contributions among DeFi pros, while immutability is a crucial necessity for the DeFi landscape to provide assurance of security. Decentralization, of course, means more transparency, and the distributed ledger keeps track of all transactions on the blockchain network.

The cryptographic principles of blockchain also ensure that information is only documented when it has been verified as valid.Transparency in DeFi applications, for example, could help with due diligence. Simultaneously, DeFi programmes may assist users in recognising and avoiding potential financial scams as well as unethical commercial activities.

🔶️ LENDING AND BORROWING APPS:-
DeFi has played a major role in the growth of peer-to-peer lending and borrowing solutions. Decentralized finance would definitely reflect on cryptographic verification procedures, as these forms of loan and borrowing solutions offer highly promising benefits for end-users.
They also provide the certainty of smart contract integration at the same time. The availability of such functionalities eliminates the need for intermediaries such as banks, which are typically in charge of verifying the participants to a transaction. It can also be used to verify the processes involved in lending and borrowing.

As a result, DeFi makes the verification procedure for loan and borrowing applications faster and easier.
Lending and borrowing applications are currently the most well-known DeFi applications.

🔶️ SAVING APPLICATIONS:-
The benefits of decentralised finance also shine a focus on DeFi savings products growing prominence. DeFi might potentially be used to help people manage their funds more effectively. Users capable of to begin earning interest on assets that they have locked in lending protocols such as Compound. As a result, a slew of DeFi-based savings apps have popped up in recent years.
DeFi ecosystem, in particular, for demonstrating how consumers move their idle crypto assets between several loan protocols in order to maximise returns.

🔶️ TOKENIZATION:-
Any discussion of the benefits of DeFi would be incomplete without mentioning the benefits of tokenization. Tokenization is the most talked-about concepts in the blockchain world right now. Ethereum permits extensive smart contract capabilities, paving the way for crypto token issuance.
Crypto tokens functioned as digital assets on a blockchain with a variety of functions and applications.

Tokens include utility tokens that are exclusive to a particular dApp, real estate tokens, and security tokens, to name a few.Digital currencies, fiat currencies, oil, and gold are all possible assets. Tokens in Ethereum-based smart contracts serve as collateral for crypto-synthetic assets. Synthetix, one of the largest synthetic asset platforms, now has roughly $600 million in smart contracts locked up.

💠 Discuss any DEX project built on the following network.

So I selecet pancakeswap which is bulid on binance smart chain .

PANCAKESWAP 🥞:-
PancakeSwap is a decentralised exchange that enables you to swap cryptocurrencies and tokens without the need for a centralised intermediary while maintaining custody of your tokens. It is based on Binance Smart Chain's automated smart contracts.

Despite the fact that Binance runs a controlled exchange, it does not own or operate PancakeSwap, which was created by anonymous developers. The service has a similar look and feel to Uniswap, a prominent Ethereum DEX. Although tokens from other platforms can be sent over via Binance Bridge and "wrapped" as BEP-20 tokens for use on the DEX, PancakeSwap is only for BEP-20 coins operating on Binance Smart Chain.

🔵 FEATURES:-
PancakeSwap allows game-like experiences, such as wagering on whether the cost of Binance Coin (BNB) will climb or fall in a specific time frame. It feature a lottery component that allows users can buy a ticket in the hopes of winning a large sum of CAKE, and the DEX sells a variety of bunny-themed collectible non-fungible tokens (NFTs). There are also (IFO) sales, which allow you to purchase fresh new coins from newly launched projects.

PancakeSwap bypasses centralised exchanges' intermediaries, allowing other users to gain the benefits instead. The returns can be substantial if you're ready to lock up your tokens for a while, especially with some of the liquidity pools and staking alternatives.

Granted, as with other DEXs, crypto rookies will have a difficult time navigating PancakeSwap and comprehending its many features. Taking the effort to figure it out, though, might be worthwhile.

🟣 WORKING:-
Token swaps take place between token pairs using liquidity pools, as detailed above. Users can swap crypto token for another crypto token without the need for a middleman, and users who stake their tokens in liquidity pools get a percentage of the transaction profits.

However, that is only a small portion of the PancakeSwap experience. The Decentralized Exchange ( DEX ) allows you to invest coins in so-called Syrup Pools, which offer increasing payouts. For example, by staking PANCAKESWAP (CAKE), and letting it sit in the Syrup Pool for a while, you can earn even more CAKE. There's even an auto-stake option that automatically re-stake your CAKE at least once every hour, increasing your rewards exponentially.

🟢 FUTURE OF PANCAKESWAP (CAKE):-
Developers are gathering together to Binance Smart Chain because of its low fees and faster transactions compared to Ethereum. Binance said in April 2021 that the platform has completed 4.9 million transactions in a single day, which is three times the amount of transactions that Ethereum has ever completed in a single day.

As we know PANCAKESWAP(CAKE)may not have the same level of average daily volume as Uniswap or SushiSwap, Ethereum's two most popular heavyweight DEXs, it is already highly popular given Binance Smart Chain's young age.

If Binance's decentralised app (dapp) platform continues to grow and attract more developers and users, and Ethereum's skyrocketing gas fees and network congestion persist, PancakeSwap may be able to compete with famous like Uni and Sushi exchanges even more effectively in the future.

This lecture was very helpful to me and I learned a lot from this lecture. I learned from this lecture that what is DeFi and complete detail about . I learned how we can swap our crypto assets with the help of DEX . I have learn about the advantages of defi system . Overall this lecture gave me a lot of knowledge about DeFi . Thank You Dear prof @reminiscence01 For this lecture.
