Yes, you guessed it, it's time for a new episode of back to school! A little before launching this series of articles, we had already touched on the subject of web 3.0 by vaguely exploring what the latter meant.

Today we're going to dive more specifically into the differences between web 1, web 2 and finally web 3.0. We will also answer the question: Will web 3.0 replace web 2.0 in the same way that web 2 replaced web 1? Are you ready? Let's get started!

A little history: Web 1.0 

The Internet has gone through two significant incarnations thus far. Web 1.0, which consisted of static "read-only" web pages developed by a very limited number of contributors, launched the Internet in the late 1980s. Since anyone in the globe could now access published content, this was undoubtedly a significant advancement.

Users could read and explore these web sites, but they were limited in how much further interaction they could have. Additionally, using the World Wide Web (WWW) was not as straightforward as it is today because there were no search engines at the time.

A revolution: Web 2.0

Web 2.0, however, had already begun by 2000. This updated version allowed for much more user involvement and participation, in contrast to the earlier iteration, which mainly included a single flow of information from the Internet publisher to the Internet user. Users can set up their own accounts in a variety of programs, which means they have a distinct online identity.

This created enormous commercial prospects, particularly for e-commerce, as it allowed new Internet enterprises to reach a large online user base at a low cost.

It also meant that anyone, wherever in the world, could contribute content for a worldwide audience, giving rise to the highly successful Wikipedia and the widely adopted blogging fad.

Of course, we shouldn't overlook Web 2.0's contribution to the development of social media, including Facebook, Twitter, and YouTube. These interactive web platforms were made possible thanks in large part to the advancement of web technologies like JavaScript, HTML5, and CSS3.

The new paradigm? : Web 3.0

This is where we introduce Web 3.0, a replacement for the current web architecture. The World Wide Web is turning into a data storage system as a result of the growth of online interaction and consumption. It makes it easier to modify the backend of the Web after spending a lot of time on the front end, which was one of Web 1.0's characteristics and was reinforced by Web 2.0.

Web 3.0 is characterized by decentralization, which suggests that the network is powered by millions of computers dispersed throughout the globe rather than a few corporate data centers. Blockchain technology serves as an inspiration for this decentralized network.

Web 2.0 has increased the social aspect of the internet. This phase saw the growth of massive volumes of data and content on the Internet as users were urged to interact with one another via social networking sites and blogs.

Contrarily, at the current phase of the Web 2.0 revolution, these data and content are mostly under the hands of a small number of technology behemoths, like Amazon, Apple, Meta (previously Facebook), Microsoft, and Google. It should be easier to get beyond this obstacle knowing that Web 3.0 is meant to be a decentralized form of the Internet where users own their data. As a result, the third generation of the Internet will be more open and transparent.

Could Web 3.0 replace Web 2.0 ?

Some think that the technology will, at most, complement Web 2.0 but not entirely replace it. In other words, blockchain-based social networks, transactions, and businesses may continue to expand and prosper in the years to come. Some people disagree, though, and believe that Facebook, Twitter, or Google won't be totally replaced anytime soon.


Web 3.0 is still in its infancy, even if the development of decentralized applications and blockchain now goes back a good ten years. It's hard to say exactly if web 3.0 will completely replace web 2.0, at least in the short term. Indeed, for the moment, data remains the prerogative of the big tech companies we all know.

A new paradigm may be born, but it is still too early to consider it completely! See you next week for a new episode of "Back to school"!
