What is WEB3? Why is it important! (Simply Explained)

Famously known as web 3.0, web3 is an era referring to decentralization. Whether it is decentralized apps commonly known as DApps or decentralized finance generally called as DeFi, Web3 is changing the way we browse on the internet entirely.

To understand Web3 easily, the basic understanding of web1 and web2 will be useful. It will help us to understand how technology evolved from just static and read-only web pages to fully dynamic and interactive designs. So let’s dive in.



What is WEB 1.0?

The age of the internet starts from the web1 also known as web 1.0. This is the era from 1991 to 2004. In this technology evolution. The web was more like an online directory.

All the websites had static web pages. This version of the internet was read-only. The websites were not dynamic which means you can only view and read the information and can not provide any info to the person who owns the website.

During the span of web 1.0, the users were the consumers. They search on the internet about the businesses and get the results. But the users were not able to make any purchases online.

What is WEB 2.0?

The second technology evolution started with web 2.0 also known as web2. This was the era from 2004 to 2021. During this time, technologies like Javascript along with many other similar technologies enabled us to interact with the pages.

In web 2.0, the users were able to submit forms and make purchases online that emerged as a giant eCommerce market across the world.

In this era, we have big companies like Microsoft, Google, Facebook, and many many more. These companies collected from the users to serve in a better and efficient way.

Web 2.0 was the age of the targeted advertisement. As the companies were already data from their users, these companies used it to show targeted ads to the customers.

But in the meanwhile, some big companies started selling the data of their users. They used to sell the data to other companies.

All the companies that we saw during the revolution were centralized. This means that a single person has the authority over the entire company including the data of their users. This sounds scary sometimes and resulted in the web 3.0.

What is WEB3?

The major that we faced in web 2.0 was the security of the user’s data. The data was not impossible to hack. We have seen many data breaches from tech giants companies.

These were the strong basis for the next revolution of the internet. In 2009, Satoshi Nakamoto created a technology which is called blockchain used mainly to create a digital currency, bitcoin.

Bitcoin Technology is the core foundation of the WEB3 also known as WEB 3.0. We have entered the next evolution of the internet. WEB3 uses blockchain technology and tools of decentralization to build the internet.

The term decentralization means that in the era of WEB3, no single authority will control the data of the billions of users. Instead

Everyone will own the internet.

In WEB3, the users will be able to have full control over their data. They can control what they want to share and what they do not want to share over the internet.

As WEB3 is based on blockchain technology, it is almost impossible to hack. You can read our beginner’s guide for blockchain technology to understand more about blockchain.


The journey started from WEB1 to WEB3 was pretty surprising. From just static pages to fully dynamic and secure. Web3 is the future of the internet. Sooner or late, we will see some big companies in this field also.

with the increased security, WEB3 is the future. You should look deep into it. Try to find opportunities in this and there is very low competition in this field. To study more about WEB3 and blockchain technology you can read our detailed guide on blockchain technology.
