> Greetings,
Welcome to all of you guys in my post. I am Hammad. with another homework in this wonderful community. today's, post is related to Sidechain. I am thankful for prof. @pelon53. so, let's get started without wasting any time. ![Green Gridded Geography Quiz Presentation(1).jpg](https://cdn.steemitimages.com/DQmXR1v9nzTfEpeLWjot2KxUEednomdVrzHz3LZpr5m4VbS/Green%20Gridded%20Geography%20Quiz%20Presentation(1).jpg)
# Introduction: Everything in this world is working according to its procedure. what happens if these things do not follow a rule or guidance. obviously, everything is messed up. let's take an example for example you cooked Noodles so, you need to follow some path like first, you take Pan and put water into it and then follow the further procedure. The same path is followed in Blockchain Technology, and we know that blockchain technology is fully working with the internet. but the major drawback is traffic in Blockchain to avoid this a new concept is come which is Sidechains.

# Sidechain:
We will discuss the ZK-Rollups later, first, we need to understand the Sidechains in dee. so, basically, the Sidechains Secures and makes efficientthe Blockchain networks. it reduces the noise between the network. sidechains are the two-way blockchain network and these networks are connected to each other. Sidechain process the data from the main Blockchain. the main blockchains are very slow. some of the sidechains are a little centralized but it is ok. because it secures our network and makes it efficient. miners or validators also used the side chains because it is fast and the overall working is the same as the main chain. sidechain also follows algorithm rules like proof of stake, proof of work, and proof of Space.
# ZK-Rollups:
Now, here we discuss the ZK-Rollups. so, the zk-rollups provide the second layer of transactions. as we all know that the role of plasma is to create one transaction per rollup but the zk-rollups provide multiple transactions per rollup. It provides very well scalability to the Bulk transfers which roll into the single transfers rollup. In the block of every blockchain, validity is required to secure the block. in this scenario, the ZK-Rollups provide better storage and more efficient computational power which reduces the amount of data. and that is very helpful to do the transactions. let's discuss the drawbacks and the advantages of rollups: ## Advantages of ZK-Rollups:
1. It is more efficient than the side chain. 2. less amount network fees are required. 3. fully decentralization because blocks encourage parallel computation power. 4. More faster and reliable.
## Disadvantages of ZK-Rollups :
1. because of quantum computing the chance of hacking is very high. 2. the security of the data in ZK-Roll up is non verifiable.

![1.7.png](https://cdn.steemitimages.com/DQmeM6qeXUnAsdZ6x56amLkr6bajVQWoNJiYCazj77eZzdw/1.7.png) Source The concept of Liquid Network side chain are come in year 2017. Adam Back is the founder of Block Stream. the purpose of liquid network side chains is to enhance and unlock the higher speed of transactions in the network, it also enhances the security and provides very handy privacy to the side chains. BLock stream is the first side chain of the Bitcoin network.
here are some features of Liquid Side blockchains:
1. Faster: The Liquid side blockchains provide faster speed as compared to the main network blockchain. 2. less time consuming: if we talk about the main bitcoin blockchain the transaction time is very high 10 mins but in a liquid network blockchain this time is reduced up to 8 minutes. so, in liquid side chains, the transactions time is 2 mins. 3. Suppports Different Tokens: Liquid side chains supports different type of token in the Bitcoin network. ![1.8.png](https://cdn.steemitimages.com/DQmWZHRfkACtx2wQ9ThmW2E3DUZTCnF7auuMzSdV8zPXcnu/1.8.png) Source
# Two Way Peg: ![2.0.png](https://cdn.steemitimages.com/DQmXZsp93dEPEeRzjp1J6PombTS37QVcYq5RsnCKAkoVun2/2.0.png) Source
The Peg is the way to convert the BTC to L-BTC. this process is the two-way first one is Peg-In and the second one is Peg-out. this way provides the user and eases the transactions between the networks. this process is done within 2 minutes. both the transactions like BTC and L-BTC have the same ratio like 1:1 The liquid network's side chain is very faster. even a Bitcoin as we know the BTC network is very time-consuming transactions but the Liquid network reduces this transactions time. the very next feater of this Liquid chain is another token that will be supported in the BTC network. this feature allows the trader to change the BTC network to the Liquid side chains because it is faster. The future of the Liquid chain's network is very bright because of its handy features. they show their monopoly for both traders and exchanges. ![color.png](https://cdn.steemitimages.com/DQmRkQ15zcU2ZqnWUE18orDNjuDewpC7JiaGNX6Mf9mv7vg/color.png) ## Describe the steps to connect the Metamask wallet and the Polygon network wallet ![color.png](https://cdn.steemitimages.com/DQmRkQ15zcU2ZqnWUE18orDNjuDewpC7JiaGNX6Mf9mv7vg/color.png) In this particular question we are following the following steps : > Step # 01: First, we need to go to the polygon network. see in the screenshot: ![1.1.png](https://cdn.steemitimages.com/DQmS7aavbvXDXAp6btER3q4BqyNMunfio5QfGwgDpwszRoo/1.1.png) Source

Explore the 12,000,000 block, at that time, what was the price of the Matic? ![color.png](https://cdn.steemitimages.com/DQmRkQ15zcU2ZqnWUE18orDNjuDewpC7JiaGNX6Mf9mv7vg/color.png)
first I will go to the polygon official website and search the block 25000000. here is the image. ![4.1.png](https://cdn.steemitimages.com/DQmQu4mRwBdtbHD8iZQumMFcfjMhJPAdmBf2joeR3UEwYWZ/4.1.png) here is some data which is shown. Estimated Target Date: Tue Feb 15 2022 04:26:31 GMT+0500 (Pakistan Standard Time) ![4.2.png](https://cdn.steemitimages.com/DQmbroeXuEa3dQ7QTGrmuGTPTwyTkuYiQsCt7kzKL2U6GtZ/4.2.png) when the value is 12,000,000 the price of matic is 1.90 at that time ![4.3.png](https://cdn.steemitimages.com/DQmaHAzKkqcKUh6iUsKckTJPZR22zM12VKbCYm34urpyJAT/4.3.png)
# Conclusion:
In the end, I say that the sidechain is very handy it provides better functionality to its miners and validators. the Liquid sidechain is also suitable for the bitcoin networks and currently, most of the exchanges are used this liquid side chain. so, that's it I hope you like it.
