The Internet is the most important asset of the present time without which we cannot imagine our personal & professional life. You must have heard about Web 3.0 where we all are heading.

Most of us know about the various eras of the world wide web. Today we are at the third version of the internet that empowered mankind in a more meaningful way.

After the static era of the internet, web 2.0 and web 3.0 have accelerated the mode of communication by a million times.

In our previous blog, we discussed what is Web 3.0 Click on and get complete information about the concept.

Here, we will discuss the migration from web 2.0 to web 3.0. Most of the developers or technocrats are still unaware of the same. Being a responsible software development company in India, sharing knowledge is our job.

What is Web 2.0?

Web 2.0 brought the concept of social media and user-generated content. The world became more interactive with web 2.0. With the help of social media, we were able to communicate across the world frequently.

Also, it helped businesses to promote themselves on a large scale. If we say, web 2.0 has given birth to the powerful digital era, it will not be wrong. Presently, we can sell our products in overseas countries simply by sitting at home. It is all because of web 2.0.

If we talk about statistics, there are 750 million internet users in India only. Further, 5 million domains (web) are booked by our country only.

And for the USA, internet users are 300 million and they hold more than 130 million domains. The data clarifies that domain penetration in the US is about 43%.

The technologies involved in web 2.0 are traditional and it revolves around HTML and CSS. Hence it offers a static experience as compared to web 3.0. As we know, change is the law of nature and so with technology.

Now, web 3.0 is acquiring the world and we must know about the same. As a leading web development company in India and USA, we know lots of people don’t know the difference between web 2.0 and web 3.0. Hence we are mentioning them individually.

What is Web 3.0?

The ultimate aim behind any digital concept is to make communication fast, and transparent. The objectives are achieved more precisely with the arrival of web 3.0. We always feel that we should move ahead with recent technologies otherwise you will be left far behind.

Why should we adopt Web 3.0?

Web 3.0 has given a new birth to the digital world where connectivity is strengthened along with complete security. Deliverance of web 3.0 are:

  • Fast Communication
  • Targeted Result
  • No Central Authorization for Communication
  • More Secure & Quick

The concept of Web 3.0 revolves around data and it is more decentralized. Artificial Intelligence and Big Data are the major driving force of web 3.0.

Now, users are not required to communicate via central authorities like Facebook, Google, etc. They can simply interact with the help of data.

Moreover, web 3.0 acquires data using simple algorithms and sensibly uses the huge data available over the internet. Also, it provides more genuine and precise output to the end users.

Web 3.0 takes care of users’ privacy through personalization & customization. Also, the technology delivers a more interactive environment using the emerging technologies that IoT (Internet of Things). AI (Artificial Intelligence), ML (Machine Learning), and VR (Virtual Reality).

We know, technologies are made for our ease. Sometimes learning them becomes challenging but this is the only way to grow as a professional.

Web 3.0 is here to make communication quick and interactive without the involvement of any central authority. This means we can say, users will be their own masters now.

How To Migrate From Web 2.0 To Web 3.0

Moving from one version of technology to another should be smooth and hence one should always focus on it. As we have stated above, many developers are not aware of the migration from web 2.0 to web 3.0. Let’s move towards the same.


Web 2.0 follows traditional authorization via cookies and Web 3.0 requires the user to with the wallet. The code for connection can be confusing and boilerplate. You can have lots of libraries for high-level abstractions.

Data Reading

There are not many options available for data retrieval in web 2.0. Using “fetch” & “Axios” it can be done. And in Web 3.0, using contract address and its ABI, developers can make a smart contract instance. Furthermore, to interact with the blockchain, the well-known library is “Ethers”.

One thing is very important here. As a frontend developer, you must know, if you are reading any number type value from “smart contract”, it will be “BigNumber” rather than being “number” only. It implies the data needs to be converted into a string. And in the case of numbers, they should use the “toString()” method.

Data Writing

Like reading of data is done through a “smart contract”, writing also requires the same instance. Developers are required to call the “wait()” method. It allows smart function calls to wait for the confirmation of the transaction. And the syntax for writing data is the same as reading data using smart contracts.


Still, web 3.0 is under development and we are at the very early stage. We believe, following any leading technology fundamentally is always beneficial for us. And if you are looking to make your career in a software development company, focus on it.
