## Introduction

In the past, while using the semantic web technology that [Sir Tim Berners-Lee](https://home.cern/science/computing/birth-web/short-history-web#:~:text=Tim%20Berners%2DLee%2C%20a%20British,and%20institutes%20around%20the%20world.) created in 1989, the content was published but users were not given the option to leave comments or make any other kind of input. And at this point, everyone was forced to use Web 1.0, an iteration that only permitted users to read the material.


Thus, [Tim O'Reilly](https://www.newworldencyclopedia.org/entry/web_2.0#:~:text=Tim%20O'Reilly%20is%20generally,as%2Dinformation%2Dsource%20model.) helped spread the word about the emergence of Web 2.0 in 2004. The ideology and goals of this movement were centered on social networking, mobile, and cloud initiatives, which facilitated user interaction and gave content creators the freedom to write and publish content with ease.

Wikipedia states that "Web3 was first founded by Ethereum Co-founder [Gavin Wood](https://en.wikipedia.org/wiki/Web3#:~:text=The%20term%20%22Web3%22%20was%20coined,companies%2C%20and%20venture%20capital%20firms.) and the idea gained interest in 2021 from [cryptocurrency](https://www.investopedia.com/terms/c/cryptocurrency.asp) enthusiasts, large technology companies, and venture capital firms. 
However, in this article, we'll focus on what web3 is, and know if web3 is a Metaverse, the skills-set in web3, tools used in web3, and finally, talk about where you can learn Web3.

## What is Web3 in a nutshell?

[Web3](https://en.wikipedia.org/wiki/Web3) is a new evolution of the internet that runs on a [decentralized](https://aws.amazon.com/blockchain/decentralization-in-blockchain/) infrastructure such as blockchains; more open in decision-making and permission-less. It comes with the integration of Ether that transacts value both in finance and digital services, such as storage, bandwidth, and computation without the risks of downtime, interdiction, fraud, or 3rd-party intrusion.
Keynotes:
Open: This is open because web3 is built from an open-source software that allows developers around the world to easily share ideas and collaborate as a community.
Permission-less: it grants both users and suppliers the authorization to carry out any form of activities without government permission.
Ownership: in that, it allows individuals to have full control over their data. 

## Is Web3 a Metaverse?
Okay, before we get into whether [Web3](https://en.wikipedia.org/wiki/Web3) and [Metaverse](https://www.techtarget.com/whatis/feature/The-metaverse-explained-Everything-you-need-to-know) are the same things, consider the proposed feature that comes with both technologies.

**Web3 has the following features:**

- A decentralized system.
- An open-source application system
- A new era of the world wide web
- Ownership over digital assets
- Permission-less

**Metaverse has the following features:**

- A virtual world
- Digital avatars
- Decentralization
- Experiences
- Creator economy
- Security
- Human interface technologies
- Infrastructure
- persistence

On the other hand, each technology serves a distinct purpose. Through the use of [virtual reality](https://en.wikipedia.org/wiki/Virtual_reality) (VR), [augmented reality](https://www.investopedia.com/terms/a/augmented-reality.asp#:~:text=Augmented%20reality%20(AR)%20is%20an,and%20business%20applications%20in%20particular.) (AR), [artificial intelligence ](https://en.wikipedia.org/wiki/Artificial_intelligence)(AI), social media, and digital currency, the metaverse is a virtual world that the user can access from the real world. While web3, a new development of the web, gives users the ability to read, write, and govern their privacy.

## Conclusion
We've now concluded this earlier article on the introduction to web3, where we discussed the history from [web1.0](https://www.geeksforgeeks.org/web-1-0-web-2-0-and-web-3-0-with-their-difference/) to web 3.0. Additionally, the features of the metaverse and web3 were highlighted, and a resource platform was offered so that people could study web3 and continue to contribute to the ecosystem.
