Web3 Simple Guide

Web3 is booming and there is no stopping it. It's not a new technology, but at the moment it's gaining traction with the masses. It is the next major thing for web-based development. Opportunities for employment in the web3 field are growing day by day. There is a huge demand for blockchain developers, Web3 developers, and other positions related to web3. There are many jobs and opportunities for web3 developers and the demand will continue to grow in the near future.

If you are a novice in the web3 development space it may be difficult to understand certain terms and concepts. Let's look at the significance of these two terms: Web2 as well as Web3.

WEB2

Web2 is the second revolution of the internet. It refers to the period in which the number of the content creator on the web has increased. Before Web3 Simple Tutorial, Web1 was mostly end-user-oriented. It was used to consume information.

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

Web2 is also known for the centralization of the data. Large corporations control the data of the whole globe. One company owns multiple companies , which means they can acquire data from multiple sources. This is one of the major issues facing the internet2 and caused the new revolution of the internet.

WEB3

Web3 is thought to be the next revolution of the internet. Web3 is the decentralization of information through blockchain-based applications and the use of tokens to facilitate economic transactions. Web3 is 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 considered it a trend that won't last for long. Some do believe that there is a future for Web3 because of these reasons:

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

Companies are building tools that assist in the process of development. There are grants available for web3 projects

I strongly recommend web developers to test the web3 at least for once. Web2 and Web2 as well as Web3 will be able to coexist 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 person (or group of people) with the assumed pseudonymous name Satoshi Nakamoto in 2008. Blockchain solved the issue that data was distributed across the world via Web2. As the data is shared between the various nodes, there's no one particular person or organization with all the information.

Web3 Applications are founded on the blockchain concept. Bitcoin is a use case of blockchain. It is a ledger system for payment however it is also a platform to conduct any type of data transaction. There is various network based on blockchain like Ethereum, Polygon, Solona, Avalanche, and other.

Dapp or Decentalized application are those application that uses smart contracts, which are deployed on a blockchain netwrok for its functioning.

dApp

Dapp(Decentralized application) is the same app that is a web application but with the only extension of smart contracts. You can divide the Dapp into the following parts:

It's the norm in web development. You need to develop your front-end using HTML, CSS, and JavaScript. You can use any framework such as React, NextJS, or any other framework.

You can use the backend to communicate with the smart contract deployed over the network. You can implement this in your frontend too, but separate the frontend and the backend will 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 structure that is required to develop of an dApp.

Smart Contracts

Smart contracts are computer-generated software that is not modifiable after being installed, and are automatically executed when the criteria defined in it meet.

In simple terms smart contracts are computer-generated programs written in a programming language. They cannot be modified i.e, can't make changes after they have been deployed. This contract has functions within it, that can be called and executed at any time. It can be automatically executed when defined in a specific manner. Smart Contracts form the backbone of dApp.

Smart contracts are built in blockchain networks. They have test networks which are used in the early stages of development to test the functionality of the app.

When the smart contract is activated, the execution of the smart contract will require fuel costs. Smart Contracts run on the form of a Virtual Machine. Ethereum manages the smart contract using Ethereum Virtual Machine (EVM). Ethereum Virtual Machine (EVM). The gas charges are paid using cryptocurrency. Ethereum uses Ether.
