A Web 3 Beginners Guide

by owner

There is no halting the growth of Web3. Although it is not new, it is just recently that it is becoming widely known. The future of web development is this. The number of employment openings in the web3 industry is growing daily. Web3 developers, blockchain developers, and other web3-related positions are in high demand. Web3 offers a lot of chances and jobs, and it will continue to grow.

The foundation of web3 must be strong in order to succeed. It can be challenging for a newcomer to comprehend some phrases and concepts when they first enter the web3 development field

We will therefore examine the various web3 ideas today as they will serve as the foundation for our continued study of the subject. These issues are based on the difficulties I encountered when I first entered the web3 realm. You can build subjects from there, and the possibilities are endless. Therefore, let’s begin.

PREREQUISITE

I’ll presume you’ve worked on at least one web development project and are familiar with the following before delving deeply into the world of web 3.

  • Frontend (HTML, CSS, JAVASCRIPT)
  • React, Vue.js, and other Javascript frameworks are examples.
  • Backend

These abilities are necessary to comprehend Web3 and be able to build a project around it. If you don’t know, you can learn it through the web3 trip.Your understanding of web programming will be expanded through Web3. Therefore, you must have prior experience with web programming before beginning the Web3.

HOW DO WEB2 AND WEB3 DIFFER?
Just for now, let’s determine what Web2 and Web3 mean.

WEB2

The second internet revolution is known as Web2. It alludes to the time when there have been more content producers online. Web1 used to be mostly end-user focused. It was for information consumption.

Web2 began with the emergence of social media, which enabled end users to publish content online. This makes the content creator more well-known online and eventually makes them a celebrity. Both the content producer and the consumer develop during this time.

The centralization of the data is another feature of Web2. Most of the world’s data is under the ownership of large corporations. To get various data from many sources, one company controls multiple businesses. This developed into one of the web2’s issues and sparked the most recent internet revolution.

WEB3

The next internet revolution is anticipated to be Web3. Through blockchain-based applications and the usage of the token for economics, Web3 decentralises data. Gavin Wood, a co-founder of Ethereum, popularised the phrase “Web3” in 2014. Due to the abundance of tools and platforms accessible to create blockchain-based applications, it has just lately begun to acquire popularity.

Web3 developers have conflicting opinions on it. Some others thought it was a passing fad. The next big thing in webspace is something that industry experts do consider. I support Web3 because of the following factors:

  • In recent years, a community for learning and growth has grown.
  • There are business concepts centred on web3
  • Businesses are creating instruments to aid in the development process.
  • Grants are accessible for web3 initiatives.
  • I strongly advise web designers to at least give the web3 a shot. Future Web sites will coexist with both Web2 and Web3.

Let’s proceed to better comprehend web3 now.

Blockchain is a non-modifiable ledger system that keeps track of transactions and distributes them to all nodes, or the computers connected to the network.

Ethereum Development

In 2008, a person (or group of persons) going by the alleged alias Satoshi Nakamoto popularised the blockchain. Blockchain addressed the issue of data decentralisation in Web2. Since the data is exchanged among the several nodes, no one individual or entity has complete access to it.

Applications built for the Web 3 are based on the blockchain idea. Blockchain has applications beyond Bitcoin. Although it functions as a ledger for financial transactions, blockchain may be used for any data transaction. Blockchain-based networks include Ethereum, Polygon, Solona, Avalanche, and others.

DAPP

Dapps, or decentralised applications, are programmes that operate via smart contracts that are installed on a blockchain network.

With the addition of smart contracts, a Dapp (decentralised application) is essentially a web application. The Dapp can be divided into the following sections:

FRONTEND

This is how web development works. Your front end must be created using HTML, CSS, and JavaScript. Any framework, including React, NextJS, and others, may be used.

BACKEND

To communicate with the smart contract installed on the network, use the backend. You can do this in your frontend as well, but managing the app more readily will come from keeping the frontend and backend separate.

SMART CONTRACT

The blockchain network will be used to deploy smart contracts. It will communicate with our application in order for it to operate.

A dApp is an example, such as NFT Marketplace. That pretty much sums up the fundamental format needed to create a dApp.

Let’s get into further detail about the smart contract.

Smart contracts are computer programmes that, once installed, cannot be altered and that run automatically when certain conditions are met.

Smart contracts are, to put it simply, computer programmes created in a programming language. These cannot be altered once deployed, meaning they are non-changeable. This contract contains functions that can be invoked and used as needed. If defined in a specific way, it can be carried out automatically. The core of a dApp is a smart contract.

On networks powered by blockchain, these contracts are implemented. During the application development phase, test networks are used to validate the operation of the application.

GAS FEE

Gas payments are required for the smart contract’s execution after it has been deployed. Virtual machines are used to carry out Smart Contracts. With the help of the Ethereum Virtual Machine, Ethereum controls the smart contract (EVM). The payment for these gas fees is made in cryptocurrency. Ether is used by Ethereum.

The gas price is based on how complicated the smart contract is. Gas fees rise as smart contracts become more intricate. This has been put in place to prohibit the execution of complicated smart contracts and many smart contracts on the virtual machine. A complicated smart contract can cause the system to crash.

SOLIDITY

Different programming languages, including JavaScript, Yul, and Rust, can be used to create a smart contract. Solidity is one programming language that is suggested and created for the purpose. It is a language for object-oriented programming. It is influenced by JavaScript, C++, and Python.
