in SteemitCryptoAcademy3 years ago (edited)
I'm delighted to participate in the crypto academy homework. Our professor @yousafharoonkhan gave a lecture on centralized and decentralized exchanges and also, how to use Uniswap. The homework given is straightforward and understandable because of the lecture the professor gave. Centralized and decentralized exchanges, let me start from there

What is a centralized and decentralized exchange

As instructed, the explanation should not digress from exchanges point of view. There are more than 200 cryptocurrency exchanges but they all operate differently. Based on the way each exchange operate, we can classify them as either centralized or decentralized exchange, and they are very much important in the cryptocurrency space. So on this, what is a centralized exchange
?

Write the definition of Decentralized and Centralized Exchange in your own words

A centralized exchange has to do with exchanges that transact with the help of third parties. Here, you need to give out some of your personal information to register. Else, you cannot use a centralized exchange. Examples of centralized exchanges is Binance, Bittrex, Poloniex, Kraken exchange, and more. Every transaction on a centralized exchange must pass through a process and this would not elude the administrative monitoring everything and they are in charge of the governance of the platform

This is how a centralized exchange operates

If for instance, Mike wants to buy 1 ETH, he can either go to the order on a centralized exchange and search for the offer he would like to accept, or he creates his own buying order by setting his terms of the trade in terms of price and quantity. All these will be executed with the influence of a third party and some charges must be fulfilled before the transaction can be executed


What is a decentralized exchange

Decentralized exchange operates without the third party serving as an intermediary before the transaction is executed. It can be said to be a peer-to-peer network where many points are connected. There is a high level of privacy on a decentralized exchange because the power of a third party is cut off, thereby making it easy for users to key into the system and transact without giving out any personal information. Examples of decentralized exchanges are

This is how decentralized exchanges work

If Mike wants to buy 1 ETH, he would connect with the person willing to sell directly without any third party. If the price is agreed upon, the deal will be finalized. So in this case, there is no need for any intermediary

Question no 2 :

Explain in your own words the difference between decentralization and centralization exchanges (answer should related exchanges ,not over all system.. (answer must be written in oun words, copy paste or from other source copy will be not accepted)

Differences between Centralized and Decentralized exchanges

Centralized exchange operates under a single authority, which is the company operating the exchange. Funds are kept under the control of a middle man (the exchange). Centralized exchanges operate based on order book. Here, buy and sell orders are presented in a list and the total amount is placed on each order. There is something called market debt, which is the amount of open, buy, and sell order. For a user to transact, the buy order must match with the sell order for the price of an asset and vise versa. For decentralized exchange, the case is different. Funds are transferred to the pool by liquidity providers and users can transact by swapping. There is no creation of order on a decentralized exchange. Below are the differences between CEX and DEX in a tabular form

Centralized exchangeDecentralized Exchange
A middle man act as an intermediary to facilitate trade on the platformNo middle man on decentralized exchange. It's a peer to peer transaction
In exchange for providing services, users pay a trading fee to the intermediaryNo trading fee is paid.
Not as secure as decentralized exchangesMore secure
Listing on centralized exchanges is expensive and the processes are slowListing on decentralized exchange is fast and cheap
KYC is needed. customer information is collected on centralized exchangeNo information is collected
Faster transactionsNot as fast as CEX
High liquidity because of the volume of tradeLow liquidity
Easy to useNot easy to use

Question no 3 :

write about any 2 best centralised exchanges of 2021 . why are they best in front of you? (Show screenshot of your verified profile to make verify that you are really using them, or also share any one trade that you made in last 24 hours )

There are many centralized exchanges, but some stand out because of some reasons and the reasons are what made me choose Binance and Houbi. These two exchanges are my favorite

BINANCE

When it comes to spot trading, Binance is the best. It has been dominating the world in terms of centralized exchanges with its trading volume. It has the highest trading volume and liquidity. Currently, I don't think there is a trader that won't see Binance as a place to trade, and If really there is, then we would be talking about a shred. Trading on Binance is as sweet as honey. Why? Because the interface is clean and easy to use. Since I've been teaching people how to use Binance to trade, I've never come across anyone that finds it difficult. That's my personal experience and I can categorically say that it has a good and flexible interface that a beginner can learn and use easily.

Also, the trading fee is very affordable compared to other centralized exchanges. If you are sending BUSD to another user, it costs $0. No transaction fee. Even on other cryptocurrencies, they charge very low no matter the amount. Trading on Binance with a lower fee and withdrawing with a lower fee is enough reason to adopt the exchange and make it my home of trading. I also, have another reason, but before I state it, I will like to ask a question

If you are patronizing a supermarket and they give you a huge discount, and also do giveaway for you as their customer, will you leave them and go elsewhere? That is another reason I prefer Binance to other centralized exchanges. During the December period, they did giveaway to constant users. I intentionally used the money to buy chicken and as I was tearing the chicken laps, I was laughing in Binance language. Lol

I also noticed that there is no shit coin on Binance. List your token on Binance and see how the volume would rise within a twinkle of an eye. There are many coins I've not heard but the liquidity shocks me. Coupled with the fact that BNB is doing well, It has helped the Exchange to gain more users because it pairs with different cryptocurrencies. In my opinion, Binance is the best

To trade any crypto on Binance, click on market and select the coin you want to trade. Example below

Screenshot (96)b.png

I clicked on CHR/BNB pair and it takes me to the next image below

Screenshot (95).png

Buying 8 CHR as you can see in the above image. Here, you can either buy or sell. That's a simple transaction and how easy we can trade on Binance.

Houbi Exchange

Another centralized exchange I can mention is HOUBI. This has been my favorite before I switched to Binance. Houbi have a nice interface too. In fact, I love their user interface than that of Binance. In 2013, Leon Li founded Houbi, and since then, there has been substantial growth. Why I believe Houbi is also one of the best-centralized exchange are as follows

It has millions of users in more than 130 countries and also has a trading volume that is mouth-watering (more than 1.2 trillion dollars)
It also has a high-security level, and another nice thing about houbi is that it has good customer care. When I had had issues with my account sometime ago, they attended to me professionally and the issue was resolved. If any organization has a good customer service relation, they would have a large user base, and I think that also help Houbi to come a long way. They also have a point card giveaway of $170 for new users if they complete some tasks.

Trading on Houbi is similar to trading on Binance. In fact, all centralized exchanges deal with order book.

I clicked on TRX as seen in the image above, and it directed me to the trading interface

I can from here buy or sell any coin I want. Just as simple as Binance.

Question no 5 :

How to use Uniswap exchange , and Swap/buy or swap/sell any coin (practicle step by step )

line one.jpg

How to use uniswap

First, let's know uniswap. Uniswap is a decentralized exchange that runs on the ethereum blockchain. It was built in 2018, and classified as one of the best-decentralized exchanges. It is compatible with all ERC20 tokens and some wallets like trust wallet, metamask, myetherwallet, and so on

How uniswap works

Uniswap uses smart contract to execute transactions on its platform.It uses exchange and factory contract of which they have the role they play. The factory contract adds more token to the platform as it has been programmed to perform a particular task. The exchange contract deals with all the token swaps which makes it possible for every ERC20 tokens to be swapped on uniswap.T his decentralized exchange operates through a liquidated automated protocol where users pools their fund together to create liquidity to execute trade on the platform. Anyone that put up their fund is called liquidity providers (LP's) and they receive the token that represents the stake contribution to the pool

Let's see how to use uniswap

Since uniswap is a decentralized platform, it needs a compatible wallet to connect with before transactions can occur. I use trust wallet most times, so I will be using it for my explanation.

  • If you already have your trust wallet, click on it and it will take you to the home page. On the home page, there are several features below the screen (wallet, dapps, Dex, and settings)

5c709efe-527f-4d67-973c-209d33fb556f.jpg

  • To connect with uniswap, click on dapps and scroll up. You will find Uniswap at the top. It's among the popular apps on trustwallet.- After you find uniswap, click on it, and it will direct you to uniswap.org (The main interface will be displayed)

3fa719f2-d285-4c0e-9185-7099b0e710e4.jpg

  • On the interface, there are some features at the top (Swap, Pool, UNI, and Vote). The homepage will display the swap interface

  • So to swap your token, you can click on the drop-down to select the token you want to swap.

39a41d4f-076b-4dc7-b2dd-4cbbe114cb7d.jpg

As you can see in the image, I want to swap TST for ETH. How did I do this? I clicked on the first drop down and searched for TST, then clicked. Secondly, I clicked the second drop down below and choose the token I want to swap for TST, which is ETH. I can swap for any other token so far it's listed on uniswap and it has good liquidity

c1ef31ba-d8e8-4db6-826c-09315c6f0d30.jpg

  • After this step, click on Approve TST. If the amount of TST to be swapped for ETH or any other asset doesn't have enough liquidity, there will be no way to approve TST.

036bc1d0-82cf-4410-b71a-e07a462b0001.jpg

  • The next point would be to confirm the transaction after clicking on approve TST. As you can see in the image, I'm to pay a transaction fee of $8.49 to confirm the transaction, but I'm not having a sufficient ETH balance. Had I have up to the ETH amount in my wallet, I would have clicked and completed the transaction

  • After the transaction is completed, you can then proceed to swap, which will also incur a little fee.

What some people don't understand is that if you are swapping a token for the first time, the token must be approved first, but the subsequent transactions would not require another approval. Only the swapping fee would be charged

There is another thing I won't forget to mention

There are many tokens listed on uniswap. Some can be found through search when you click the drop-down I mentioned earlier, and some can not be located. Those ones that don't pop up via search can be accessed by pasting the token contract address in the search option. So how can we get the contract address

  • Go to Coingecko

  • Type the name of the token in the search option and click on it

  • All the info about the token will be displayed. You can get the contract address from there. See below a screenshot of where to locate the contract address.

As earlier mentioned, copy the contract address and paste it in the search option where token is selected on uniswap.

Excellent Explanation about Cetralized and Decentralized Exchages and their major Differences too.

What some people don't understand is that if you are swapping a token for the first time, the token must be approved first, but the subsequent transactions would not require another approval. Only the swapping fee would be charged.

In DEX ,swapping from one to any coin first we need to sporove then swap thise. So here we need to pay Transactions Fee Two Times.

Nice Presentation from you. Take care.

Yes, we are still saying the same thing. I understand you pretty well. Thanks for coming around. I appreciate your comment. One love
