Web 3.0: What is it, what could it change?

Web revolution, mutations. Yesterday the web was static, tomorrow it will be dynamic.
We talk about Web3.0, but what is it exactly? What will be the web of tomorrow? We propose you in this quick article, to come back on this concept which floods … the web.

C'est quoi le Web 3.0 ?
Web 3.0? A matter of decentralized web.

Return to the origins

Before tackling this concept, let’s have a look at the evolutions.

Internet vs Web

Let’s start by reminding the difference between the Internet and Web. The first one is a worldwide network of computers able to exchange data while the web refers to links and content pages.

Web 1.0

The web 1.0 appeared at the end of the 80s and the beginning of the 90s, it is the version 1 of the Internet. It is called static Internet. We discovered web pages created by a few Internet users. We are talking about a time when search engines were in their infancy. The Internet was used for consultation only.

Web 2.0

Then the 2000’s came and with them the web 2.0! This time we could interact, be actors and the community of Internet users had already grown. The Internet had turned participative.

Everyone could create their own identity on the net. Everyone became an actor on the web, with the possibility to feed blogs, sites… it’s the birth of social media and of GAFAM which feed on our data. At this stage we became dependent on platforms.

The birth of Web 3.0

The web 3.0 appears in the media, on the web, and it is well debated: why? What is web 3.0? This term is not completely new.

Although there is no unique definition, let’s try to make the point on this concept.


To begin with, let us note that this term can appear under the following denominations:

  • web3
  • decentralized web
  • application 3.0
  • solution 3.0
The evolution of web versions
Web 3.0? A matter of semantic web.

Distinguishing marks

  • Independent and universal. It can be used on all media: mobile friendly
  • Integrated user interface
  • Decentralized based on blockchain (allows content authentication and certification)
  • Software application accessible online : Cloud Computing

In details

Targeted content

  • The Web 3.0 should become the smarter version of the Internet thanks to the contribution of artificial intelligence in the processing of information, the results of search engines becoming much more refined (semantic web) and more targeted. Advertisements will be more relevant: The Internet will adapt the information it provides to each Internet user.
  • The network will become accessible to all, thanks to the connection of smart devices and permissive platforms open to all. Navigation should be more efficient.

Falsification of data much more complicated

Users should regain control over their personal data, which was previously in the hands of commercial organizations. The user will become sovereign over his data. We talk about “self sovereign Identity”. The individual is at the center of the digital experience.

Technological evolution

  • The 3D Web will remove the boundaries between digital content and the real world.
  • We will see a resurgence of augmented reality, the 5G network, the Internet of Things will now be an integral part of Web 3.0.

Web 3.0 also implies:

  • The control of comments and opinions will be more difficult on a decentralized platform because anonymity will be accentuated, on the contrary the risk of censorship is reduced.
  • We will be “geolocalized” in real time: advantage? disadvantage?
  • Web 3.0 is still being built; gaps remain in terms of data storage and processing power.

Is Web 3.0 a new version of the Internet or a buzzword? What is certain is that the digital world has not finished revolutionizing itself. The web continues and will continue to undergo metamorphoses, which will provoke much debate.
