Web3 Beginners Guide

Web3 is on the rise and there is no stopping this. It is not new but at the moment it is reaching to millions. It is the next major technology in web development. The opportunities for job seekers in the field of web3 are increasing day by day. There is a huge demanded for developers of blockchain, Web3 designers, along with other jobs associated with web3. There are numerous jobs and opportunities in web3 and it will rise in the future. What is Web3

For a beginner starting in the world of web3 development, it can be hard to understand some concepts and terms. Let's just understand the significance of these two terms: Web2 as well as Web3. Simple to Understand Web3 Video Explanation

WEB2

Web2 represents the 2nd revolution of the internet. It refers to the period during which the amount of the content creator on the web has increased. Previously, Web1 was mostly end-user-oriented. It was for consuming the data.

Web2 started with the rise of social media that allows users to create content via the internet. This led to the rise of the content creator on the internet and eventually becoming a household name. The creator and the consumer develop.

Web2 is also famous for the centralization of the data. Big corporations typically manage all the data in the globe. One company has multiple companies to acquire different information from different sources. This was one of the issues for the web2 and led to the revolution that is now taking place on the internet.

WEB3

Web3 is regarded as to be the next major revolution in the internet. Web3 refers to the centralization of data via blockchain-based applications and the use of tokens to facilitate economic transactions. 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 feelings about web3. Some thought it was an unsustainable trend that will not last long. I do believe that there is a future for Web3 because of the following reasons:

Communities are growing in recent times for learning and development. There are some ideas for web3-based startups

Companies are building tools that help the development process. There are grants for web3 projects

I strongly recommend web developers to play around with the Web3 at least at least once. The two technologies Web2 and Web3 will co-exist with one another in the near future. Let's move forward to understand Web3 more thoroughly. Blockchain Development

The blockchain was first popularized by one person (or group of people) using the presumed pseudonymous name Satoshi Nakamoto in 2008. Blockchain solved the issue that data was distributed across the world via Web2. Because all data are shared between the different nodes, there is no one particular person or organization having all the data.

Web3 applications are based on blockchain concept. Bitcoin is a use case of blockchain. It functions as a ledger system that can be used for payments but blockchain can be used to facilitate any kind of data transfer. There is various network based on blockchain such as Ethereum, Polygon, Solona, Avalanche, and other.

Dapp or Decentalized application are the applications that use a smart contract, which are deployed on a blockchain netwrok for its functioning.

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

This is as it is when it comes to web design. It is essential to develop your front-end using HTML, CSS, and JavaScript. You can utilize any framework such as React, NextJS, or anything else.

The backend can be used to communicate with the smart contract deployed on the network. You can integrate this feature into your frontend too, but separate the frontend and the backend can help you manage the app more easily.

Smart Contract will be deployed on the blockchain network. Our application will interact with it for the functioning for the app. NFT Marketplace is an example of a dApp. It's basically the fundamental format required for the development of a dApp.

Smart Contracts

Smart contracts are computer-generated programs that cannot be modified once deployed, and automatically executed when the criteria defined in it are met.

In simple words, smart contracts are computer programs written in a programming language. They are not able to be changed i.e they aren't able to make any changes once deployed. This contract has functions that can be executed and called when required. It can be automatically executed when defined in a specific manner. Smart Contracts form the backbone of dApp.

Smart contracts are built using blockchain-driven networks. Test networks are available which are utilized in the early stages of development to test the functionality of the app.

When the smart contract is deployed and executed, the smart contract requires fuel costs. Smart Contracts run on a Virtual Machine. Ethereum is the one that manages smart contracts with the Ethereum Virtual Machine (EVM). The gas charges are paid in terms of crypto currencies. Ethereum uses Ether.
