Web3 is on the rise and it is not slowing down that. It's not a new technology, but at the moment it is reaching to large numbers. This is the next big trend for web-based development. The opportunities for job seekers in the web3 field are increasing day by day. There is high demanded for developers of blockchain, Web3 designers, along with other positions related to web3. There are many job and opportunities in web3 and the demand will continue to grow in the coming years.
For someone who is just beginning in the web3 development field it can be difficult to grasp certain terms and concepts. Let's first understand the meaning behind these two terms Web2 and Web3. Web3 Simple Explanation
WEB2 Beginners Explanation to Web3
Web2 refers to the second revolution of the internet. It is the time in which the number of the content creator on the web has increased. Before, Web1 was mostly end-user-oriented. It was primarily used for consumption of information.
Web2 was born out of the growth of social media which allowed users to create content via the internet. This leads to the popularity of the content creator on the internet and eventually becoming a household name. During this period the creator and the consumer increase in popularity.
Web2 is also famous for centralizing data. Big companies mostly control all the data in the world. One company owns several companies that acquire data from various sources. This is one of the problems for the web2 and led to the new revolution of the internet.
WEB3
Web3 is thought to be the next step in the evolution of the internet. Web3 involves the decentralization data through blockchain-based applications , as well as the use of tokens for economics. "Web3" is what it's called "Web3" was coined in 2014 by Ethereum co-founder Gavin Wood. It is only gaining popularity in recent years due to the abundance of tools and platforms that can be used to build the blockchain-based app.
Developers have mixed feelings about web3. Some consider it to be a trend that won't last long. Some do believe in Web3 because of the following reasons:
Community is building in recent years for learning and growth. some ideas for web3-based startups
Businesses are creating tools to help the development process. There are grants to web3 projects.
I strongly recommend web developers to play around with the web3 at a minimum at least once. Web2 and Web2 as well as Web3 will co-exist with each other in the future. Let's look ahead to learn about Web3 more thoroughly. Blockchain is a non-modifiable ledger system that keeps track of the transaction . It is shared across the node i.e the computer which is part of within the networks. Blockchain Development
The concept of blockchain was popularized by a particular person (or group of individuals) who claimed to be the pseudonymous name of Satoshi Nakamoto in 2008. Blockchain solved the issue that data was distributed across the world via Web2. Since the data is shared among the different nodes, there is no single person or entity with all the information.
Web3 applications are based on the blockchain concept. Bitcoin is a case study of blockchain. It is a ledger system that can be used for payments however it is also a platform to conduct any type of data transaction. There are a variety of networks based on blockchain like Ethereum, Polygon, Solona, Avalanche, and other.
Dapp or Decentalized Application are the applications that use a smart contracts that are deployed on a blockchain network to function.
dApp
Dapp(Decentralized application) is the same application as a web application with the only extension of smart contracts. You can divide the Dapp into the following sections:
This is the way it is when it comes to web design. It is essential to 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 over the network. You can implement this in your frontend, however segregating the backend from the frontend will help you manage the app more easily.
Smart Contract will be deployed on the blockchain network. Our application will communicate with it to ensure the operation of the application. NFT Marketplace is an example of a dApp. It's basically the fundamental structure that is required to develop of a dApp.
Smart Contracts
Smart contracts are computer programs that are non-modifiable once installed, and are automatically executed as long as the conditions specified in the contract are met.
In simple words Smart contracts are computer programs written in the 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 whenever needed. It can be automatically executed by defining it in a particular manner. Smart Contracts form the backbone of dApp.
Smart contracts are built on blockchain-based networks. They have test networks which are used during the development stage to test the functionality of the application.
After the smart contract has been activated and executed, the smart contract will require fuel costs. Smart Contracts are executed by a Virtual Machine. Ethereum manages the smart contract through EVM, the Ethereum Virtual Machine (EVM). These gas fees are paid out in the form of cryptocurrency. Ethereum makes use of Ether.
