Why Web3 is the Future of the Internet

Web3 is on the rise and there is no stopping this. It's not new, but at the moment it's reaching the masses. This is the next big trend on the web. The opportunities for job seekers in the web3 field are growing day by day. There is a high need for Blockchain developers Web3 developers, and other positions related to web3. There are numerous jobs and opportunities in web3 and it will rise in the coming years.

For a beginner starting in the world of web3 development Beginners Guide to Web3, it can be hard to grasp certain concepts and terms. Let's first understand the meaning behind these two terms Web2 and Web3.

WEB2 Web3 Tutorial

Web2 refers to the second wave of revolution on the internet. It is the time during which the amount of the content creator on the internet has grown. Previously, Web1 was mostly end-user-oriented. It was used to consume information.

Web2 started with the rise of social media which allows users to create content online. This leads to the popularity of the content creator online and ultimately becoming a household name. In this time, the consumers and creators of content increase in popularity.

Web2 is also famous for its centralization of data. Big corporations typically control the data of the whole world. One company owns several companies that acquire data from various sources. This was one of the issues for the web2 and led to the new revolution in the internet.

WEB3

Web3 is thought to be the next revolution of the internet. Web3 refers to the centralization of information through blockchain-based applications , as well as the use of tokens to facilitate economic transactions. Web3 is the term "Web3" was coined in 2014 by Ethereum co-founder Gavin Wood. The term has only gained traction in recent years due to the abundance of platforms and resources available to create the blockchain-based application.

Developers have mixed opinions about web3. Some considered it an unsustainable trend that will not last long. Some believe that there is a future for Web3 because of the following reasons:

The community is growing in recent years for learning and developing There are some ideas for web3-based startups

Businesses are creating tools to assist in the process of development. There are grants for web3-related projects.

I strongly recommend web developers to play around with the web3 at least for at least once. Both Web2 and Web3 will co-exist with each other in the future. Let's move forward to understand Web3 more thoroughly. Blockchain is a permanent ledger system that keeps track of the transaction and it is shared with the node i.e the computer which is part of within the networks. Blockchain Development

The Blockchain was popularized by a particular person (or group of people) with the assumed pseudonymous name of Satoshi Nakamoto in 2008. Blockchain solved the problem that data was distributed across the world via Web2. As all data are shared among the various nodes, there's no one particular person or organization possessing all the data.

Web3 applications are based on the blockchain concept. Bitcoin is a use case of blockchain. It works as an electronic ledger system to pay for transactions however, it can also be used to facilitate any kind of data transfer. There are many networks that are built on blockchain such as Ethereum, Polygon, Solona, Avalanche, and other.

Dapp and Decentalized applications are applications that make use of smart contract, which are based on blockchain netwrok for its functioning.

dApp

Dapp(Decentralized application) is the same program as a web application that only extends smart contracts. You can divide the Dapp into these parts:

It's the norm when it comes to web design. You must develop your front-end with HTML, CSS, and JavaScript. You can use any framework such as React, NextJS, or anything else.

You can utilize the backend to communicate with the smart contract that is deployed over the network. You can implement this in your frontend as well, but separate the frontend and the backend will help you manage the app more easily.

Smart Contract will be deployed on the blockchain network. Our application will interact with it to facilitate the use and operation of our application. NFT Marketplace is an example of dApp. This is pretty much the standard design and structure needed for the creation of an dApp.

Smart Contracts

Smart contracts are computer programs that cannot be modified once installed, and are automatically executed according to the requirements that it meet.

In simple terms Smart contracts are computer-generated programs written in a programming language. They are not able to be changed i.e they can't be modified once they are deployed. The contract is a function within it, that can be invoked and executed whenever needed. It can be automatically executed if defined in a certain manner. Smart Contracts form the backbone of dApp.

Smart contracts are deployed on blockchain-based networks. They have test networks, that are utilized in the early stages of development to check the operation of the app.

After the smart contract has been deployed after which the execution of the smart contract needs gas fees. Smart Contracts are executed by a Virtual Machine. Ethereum manages the smart contract with the Ethereum Virtual Machine (EVM). Gas fees are paid in terms of cryptocurrencies. Ethereum uses Ether.
