Web3 Easy Tutorial

Web3 is growing rapidly and it is not slowing down this. It is not new but it is now the time it's reaching the millions. It is the next major thing on the web. The job opportunities in the web3 field are growing day by day. There is high demanded for developers of blockchain, Web3 designers, along with other positions related to web3. There are many jobs and opportunities in web3 and this will increase in the near future.

For a beginner starting in the web3 development field it can be difficult to grasp specific concepts and terms. Let's look at the meaning of these two terms: Web2 as well as Web3.

WEB2 Web3 Guide

Web2 refers to the second revolution in the internet. It is the time during which the amount of content creators on the internet has grown. In the past Web3 and Blockchain for Beginners, Web1 was mostly end-user-oriented. It was used to consume information.

Web2 began with the advent of social media, which allowed users to create content online. This has led to the popularity of the creator of content on the web and eventually becoming a household name. The content creator and consumer both increase in popularity.

Web2 is also famous for the centralization of the data. Big companies mostly control all the data in the world. One company owns several companies that acquire data from various sources. This was one of the problems for the web2 and led to the revolution that is now taking place on the internet.

WEB3

Web3 is thought to be the next step in the evolution of the internet. Web3 refers to the centralization of information through blockchain-based applications and the use of tokens for economics. 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 build the blockchain-based app.

Developers has mixed feeling about web3. Some consider it to be an unsustainable trend that will not last for long. Some do believe that there is a future for Web3 due to following reasons:

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

Businesses are creating tools to aid in the development process. There are grants available to web3 projects.

I highly recommend web developers to try out the Web3 at least one time. Web2 and Web2 and Web3 will interact with one another in the near future. Let's move forward to understand Web3 more thoroughly. Blockchain Development

The blockchain was popularized by a particular person (or group of individuals) who claimed to be the pseudonymous name of Satoshi Nakamoto in 2008. Blockchain solved the problem of decentralization of data in Web2. As information is distributed across the different nodes, there's no single person or entity 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 is also a platform to facilitate any kind of data transfer. There are many networks that are built on blockchain like Ethereum, Polygon, Solona, Avalanche, and other.

Dapp or Decentalized application are applications that make use of smart contracts, which are deployed on a blockchain network to function.

dApp

Dapp(Decentralized application) is the same program that is a web application but with the only extension of smart contracts. It is possible to split the Dapp into the following parts:

This is the way it is when it comes to web design. You must have your front end developed using HTML, CSS, and JavaScript. You can use any framework such as React, NextJS, or any other framework.

You can utilize the backend to connect to the smart contract that is deployed in the network. You can implement this in your frontend too, but separating the frontend and backend will help you control the app with ease.

Smart Contract will be deployed on the blockchain network. Our application will interact with it for the functioning and operation of our application. NFT Marketplace is an example of dApp. It's basically the fundamental structure that is required to develop of an dApp.

Smart Contracts

Smart contracts are computer software that is not modifiable after being implemented, and executed automatically when the criteria defined in the contract are met.

In simple words smart contracts are computer programs that are written in the programming language. They cannot be modified i.e, can't make changes once deployed. This contract includes functions that can be called and executed when required. It can be automatically executed by defining it in a particular manner. Smart Contracts form the backbone of dApp.

Smart contracts are deployed on blockchain-based networks. They have test networks, which are utilized during the development stage to verify the working of the application.

After the smart contract has been implemented after which the execution of the smart contract needs fuel costs. Smart Contracts are executed in a Virtual Machine. Ethereum is the one that manages smart contracts using Ethereum Virtual Machine (EVM). Ethereum Virtual Machine (EVM). Gas fees are paid in terms of crypto currencies. Ethereum makes use of Ether.
