Web3 and Blockchain for Newbies

Web3 is growing rapidly and there is no stopping it. It's not new, but at the moment it is reaching to millions. It is the next major technology in web development. The job opportunities in the area of web3 are growing every day. There is a high need for Blockchain developers Web3 designers Web3 Video, along with other jobs associated with web3. There are many job and opportunities in web3 and this will increase in the coming years.

If you are a novice in the web3 development field, it can be hard to comprehend some terms and concepts. Let's first understand the meaning behind these two terms: Web2 as well as Web3.

WEB2

Web2 is the second revolution in the internet. It is the time in which the number of the content creator on the internet has increased. Previously, Web1 was mostly end-user-oriented. It was used to consume information. Web3 Easy Tutorial

Web2 began with the advent of social media, which allowed users to create content online. This leads to the popularity of the creator of content on the web and eventually becoming a household name. The consumers and creators of content grow together.

Web2 is also famous for the centralization of the data. Large corporations manage the data of the entire globe. One corporation owns multiple companies to acquire different data from various sources. This was one of the problems for the web2 and led to the new revolution in the internet.

WEB3

Web3 is regarded as the next revolution of the internet. Web3 is the decentralization of data via blockchain-based applications and the use of the token to facilitate economic transactions. The term "Web3" was coined in 2014 by Ethereum co-founder Gavin Wood. It has gained popularity recently due to so many resources and platforms available to develop 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. Some do believe that there is a future for Web3 due to following reasons:

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

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

I highly recommend web developers to try out the web3 at least for once. Both Web2 and Web3 will co-exist with one another in the near future. Let's look ahead to learn about Web3 more thoroughly. Blockchain Development

The Blockchain was popularized by a particular person (or group of individuals) with the assumed pseudonymous name of Satoshi Nakamoto in 2008. Blockchain solved the issue that data was distributed across the world via Web2. Since all data are shared between the various nodes, there's no one particular person or organization possessing all the data.

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

Dapp and Decentalized applications are those application that uses smart contracts, which are deployed on a blockchain network for the purpose of its operation.

dApp

Dapp(Decentralized application) is the same app that is a web application but that only extends smart contracts. It is possible to divide the Dapp into these parts:

This is the way it is with web-based development. You must have your front end developed with HTML, CSS, and JavaScript. You can utilize any framework, like React, NextJS, or anything else.

You can utilize the backend to communicate with the smart contract deployed on the network. You can integrate this feature into your frontend as well, but separating the frontend and backend will allow you to manage the app easily.

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. 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 when the criteria defined in it are met.

In simple words, smart contracts are computer programs that are written in the programming language. They cannot be modified i.e they can't be modified after they have been deployed. The contract is a function that can be invoked and executed whenever needed. It can be executed automatically if defined in a certain manner. Smart Contracts form the backbone of dApp.

Smart contracts are implemented in blockchain networks. They have test networks which are utilized during the development stage to test the functionality of the application.

When the smart contract is deployed and executed, the smart contract requires gas fees. Smart Contracts are executed by the form of a Virtual Machine. Ethereum is the one that manages smart contracts through Ethereum Virtual Machine (EVM). Ethereum Virtual Machine (EVM). Gas fees are paid in terms of crypto currencies. Ethereum makes use of Ether.
