Web3 Simple Tutorial

Web3 is booming and there is no stopping it. It is not new but at the moment it's reaching the masses. It's the next major trend in web development. Opportunities for employment in the area of web3 are growing every day. There is a high need for Blockchain developers Web3 developer, as well as other related jobs in web3. There are many job and opportunities in web3 and the demand will continue to grow in the future.

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

WEB2

Web2 is the second wave of revolution on the internet. It refers to the period during which the amount of the content creator on the web has increased. In the past, Web1 was mostly end-user-oriented. It was for consuming the information.

Web2 started with the rise of social media What is Web3, which allows users to create content via the internet. This has led to the popularity of the content creator on the web and eventually becoming a household name. In this time, the creator and the consumer grow together.

Web2 is also known for centralizing data. Large corporations control the data of the whole world. One company owns several companies that acquire data from multiple sources. This is 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 the next step in the evolution of the internet. Web3 is the decentralization of data via blockchain-based applications and the use of tokens to facilitate economic transactions. "Web3" is what it's called "Web3" was coined in 2014 by Ethereum co-founder Gavin Wood. It is only gaining popularity in recent years due to the abundance of tools and platforms that can be used to create the blockchain-based application.

Developers have mixed feelings about web3. Some consider it to be as a trend that isn't going to last long. I 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

Companies are developing tools to aid in the development process. There are grants available for web3 projects

I strongly recommend web developers to play around with the Web3 at least one time. Both Web2 as well as Web3 will co-exist with one another in the near future. Let's look ahead to learn about web3 better. Blockchain is a non-modifiable ledger system that records the transaction and it is shared across the node i.e the computer which is part of in the network. Blockchain Development

The blockchain was popularized by a person (or group of individuals) with the assumed pseudonymous name Satoshi Nakamoto in 2008. Blockchain solved the issue of decentralization of data on Web2. Since all data are shared among the different nodes, there's no single person or entity possessing all the data.

Web3 applications are based on blockchain concept. Bitcoin is a case study 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 based on blockchain network for the purpose of its operation.

dApp

Dapp(Decentralized application) is the same program as a web-based application, with the only extension of smart contracts. You can divide the Dapp into the following sections:

This is as it is with web-based development. It is essential to develop your front-end using HTML, CSS, and JavaScript. You can choose any framework like React, NextJS, or any other framework.

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

Smart Contract will be deployed on the blockchain network. Our application will communicate with it for the functioning of the application.
