Web3 Easy Explanation

Web3 is booming and there is no stopping that. It's not new, but it is now the time it is reaching to masses. This is the next big thing in web development. Opportunities for employment in the area of web3 are growing every day. There is a high demanded for developers of blockchain, Web3 designers, along with other jobs associated with 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 some terms and concepts. Let's look at the significance of these two terms: Web2 and Web3.

WEB2

Web2 is the second revolution of the internet. It refers to the period in which the number of content creators on the internet has grown. Before, Web1 was mostly end-user-oriented. It was for consuming the information. Web3 Explanation

Web2 began with the advent of social media which allows users to create content online. This leads to the popularity of the creator of content on the web and eventually becoming a household name. In this time, the content creator and consumer both grow together.

Web2 is also famous for centralizing data. Large corporations control all the data in the world. One corporation owns multiple companies , which means they can acquire information from different sources. This was one of the problems for the internet2 and caused the new revolution of the internet.

WEB3 Why Web3 is the Future of the Internet

Web3 is thought to be the next revolution of the internet. Web3 refers to the centralization of information through blockchain-based applications and the use of the token 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 lately due to the many platforms and resources available to develop the blockchain-based application.

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

Community is building in recent times for learning and growth. some ideas for web3-based startups

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

I highly suggest web developers to test the Web3 at least one time. The two technologies Web2 as well as Web3 will co-exist with one another in the near future. We must learn to comprehend Web3 more thoroughly. Blockchain is a unmodifiable ledger system that keeps track of the transactions and is shared among the nodes i.e, the computer participating on the internet. Blockchain Development

The blockchain was popularized by a particular person (or group of individuals) using the presumed pseudonymous name of Satoshi Nakamoto in 2008. Blockchain solved the problem that data was distributed across the world via Web2. Since information is distributed among the various nodes, there is no single person or entity having all the data.

Web3 applications are based on blockchain concept. Bitcoin is an example of blockchain. It is a ledger system for payment but blockchain can be used for any data transaction. There are a variety of networks based on blockchain such as Ethereum, Polygon, Solona, Avalanche, and other.

Dapp or Decentalized Application are the applications that use a smart contracts that is based on blockchain netwrok for its functioning.

dApp

Dapp(Decentralized application) is the same app as a web-based application, with the sole exception of smart contracts. It is possible to split the Dapp into these parts:

It's the norm in web development. You must have your front end developed using HTML, CSS, and JavaScript. You can choose any framework like React, NextJS, or any other framework.

You can utilize the backend to connect to the smart contract running in the network. You can integrate this feature into your frontend, however separate the frontend and the 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 ensure the operation of the application. NFT Marketplace is an example of dApp. That's pretty much the basic format required for the development of a 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 terms smart contracts are computer-generated programs written in programming languages. They are not able to be changed i.e they aren't able to make any changes once they are deployed. The contract is a function that can be invoked and executed when required. It can be automatically executed if defined in a certain manner. Smart Contracts form the backbone of dApp.

Smart contracts are built in blockchain networks. There are test networks, which are utilized during the development phase to test the functionality of the app.

When the smart contract is activated and executed, the smart contract will require gasoline costs. Smart Contracts run on the form of a Virtual Machine. Ethereum handles the smart contracts with Ethereum Virtual Machine (EVM). Ethereum Virtual Machine (EVM). Gas fees are paid using crypto currencies. Ethereum utilizes Ether.
