Web3 Simple Explanation

Web3 is booming and it is not slowing down this. It's not new, but now is the time it is reaching to millions. It is the next major technology in web development. The job opportunities in the web3 field are growing day by day. There is a huge demanded for developers of blockchain Blockchain and Web3 for Beginners, Web3 designers, along with other jobs associated with web3. There are numerous jobs and opportunities for web3 developers and this will increase in the future.

Web3 and Blockchain for Beginners

For a beginner starting in the web3 development space it may be difficult to grasp some concepts and terms. In the past, Web1 was mostly end-user-oriented. It was for consuming the information.

Web2 began with the advent of social media, which allows users to create content on the internet. This led to the rise of the creator of content on the internet and eventually becoming a household name. The consumers and creators of content increase in popularity.

Web2 is also known for the centralization of the data. Big companies mostly manage the data of the entire world. One corporation owns multiple companies to acquire different data from multiple sources. This was one of the problems for the internet2 and caused the new revolution of the internet.

WEB3

Web3 is considered the next step in the evolution of the internet. Web3 is the decentralization of data via blockchain-based apps and the use of the token for economics. Web3 is the term "Web3" was coined in 2014 by Ethereum co-founder Gavin Wood. The term has only gained traction in recent years due to the abundance of resources and platforms available to develop the blockchain-based application.

Developers has mixed feeling about web3. Some considered it a trend that won't last long. Some do believe in Web3 due to following reasons:

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

Businesses are creating tools to aid in the development process. There are grants for web3 projects

I highly suggest web developers to play around with the Web3 at least at least once. Web2 and Web2 and Web3 will co-exist with each other in the future. Let's move forward to understand Web3 more thoroughly. Blockchain Development

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

Web3 apps are built on blockchain concept. Bitcoin is a use case of blockchain. It functions as an electronic ledger system to pay for transactions however it is also a platform to conduct any type of data transaction. 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 contracts, which are based on blockchain netwrok for its functioning.

dApp

Dapp(Decentralized application) is the same app as a web application that only extends smart contracts. You can divide the Dapp into the following sections:

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

You can utilize the backend to connect to the smart contract deployed on the network. You can integrate this feature into your frontend, however segregating the backend from the frontend will allow you to manage the app more easily.

Smart Contract will be deployed on the blockchain network. Our application will communicate with it to facilitate the use for the app. NFT Marketplace is an example of dApp. This is pretty much the standard structure that is required to develop of a dApp.

Smart Contracts

Smart contracts are computer programs that cannot be modified once installed, and are automatically executed according to the requirements that it are met.

In simple terms Smart contracts are computer programs written in the programming language. These are non-changeable i.e they can't be modified once deployed. This contract has functions within it, that can be called and executed when required. It is able to be executed automatically by defining it in a particular manner. Smart Contracts form the backbone of dApp.

Smart contracts are implemented using blockchain-driven networks. They have test networks which are utilized during the development phase to check the operation of the application.

When the smart contract is activated and executed, the smart contract needs fuel costs. Smart Contracts are executed in a Virtual Machine. Ethereum handles the smart contracts with EVM, the Ethereum Virtual Machine (EVM). Gas fees are paid in terms of crypto currencies. Ethereum utilizes Ether.
