Why Web3 and The Decentralized Web Matter

Web3 is growing rapidly and there's no stopping this. It's not new Why Web3 and The Decentralized Web Matter, but it is now the time it's gaining traction with the millions. This is the next big trend on the web. The job opportunities in the field of web3 are increasing day by day. There is a high demand for blockchain developers, Web3 designers, along with other related jobs in web3. There are many job and opportunities for web3 developers and this will increase in the future.

For a beginner starting in the web3 development field it may be difficult to understand certain terms and concepts. Let's just understand the meaning behind these two terms: Web2 as well as Web3. What is Web3

WEB2

Web2 refers to the second revolution of the internet. It refers to the period where the number of content creators on the internet has increased. In the past, Web1 was mostly end-user-oriented. It was primarily used for consumption of data.

Web2 began with the advent of social media, which let the end-user create content online. This led to the rise of the content creator on the internet and eventually becoming a celebrity. In this time, the creator and the consumer grow together.

Web2 is also known for its centralization of data. Large corporations control the data of the entire world. One corporation owns several companies that acquire data from various sources. This was one of the major issues facing the web2 and led to the new revolution in the internet.

WEB3

Web3 is considered the next step in the evolution of the internet. Web3 is the decentralization of information through blockchain-based applications and the use of the token for economics. The term "Web3" was coined in 2014 by Ethereum co-founder Gavin Wood. The term has only gained traction lately due to the many resources and platforms available to build the blockchain-based app.

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

Communities are growing in recent years for learning and growth. new ideas for startups based on web3

Companies are developing tools to help the development process. There are grants available for web3-related projects

I highly recommend web developers to play around with the web3 at a minimum one time. The two technologies Web2 and Web3 will interact with one another in the near future. Let's move forward to understand Web3 more thoroughly. Blockchain is a permanent ledger system that tracks the transactions and is shared across the node i.e the computer which is part of in the network. Blockchain Development

The concept of blockchain was popularized by a person (or group of people) with the assumed pseudonymous name Satoshi Nakamoto in 2008. Blockchain solved the issue of decentralization of data on Web2. As the data is shared between the various nodes, there's no one particular person or organization having all the data.

Web3 applications are based on the blockchain concept. Bitcoin is a case study of blockchain. It is a ledger system that can be used for payments however, it can also be used to facilitate any kind of data transfer. There are many networks that are built on blockchain, including Ethereum, Polygon, Solona, Avalanche, and other.

Dapp or Decentalized application 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 with the sole exception of smart contracts. It is possible to divide the Dapp into the following sections:

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

The backend can be used to communicate with the smart contract deployed on the network. You can implement this in your frontend too, but separating the frontend and backend will allow you to control the app with ease.

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 a dApp. It's basically the fundamental format required for the development of an dApp.

Smart Contracts

Smart contracts are computer-generated programs that cannot be modified once installed, and are automatically executed as long as the conditions specified in the contract are met.

In simple words Smart contracts are computer programs written in programming languages. They cannot be modified i.e, can't make changes once they are deployed. The contract is a function within it, that can be executed and called whenever needed. It is able to be executed automatically when defined in a specific way. Smart Contracts form the backbone of dApp.

Smart contracts are built in blockchain networks. Test networks are available, which are used during the development stage to check the operation of the application.

When the smart contract is deployed after which the execution of the smart contract will require gas fees. Smart Contracts are executed by a Virtual Machine. Ethereum handles the smart contracts using Ethereum Virtual Machine (EVM). Ethereum Virtual Machine (EVM). The gas charges are paid out in the form of crypto currencies. Ethereum uses Ether.
