What is Web 3.0 and at what stage?

Web 1.0, 2.0, 3.0 and 4.0. Experts are still studying how to define them, although there is no specific marking when one era begins and the other ends. But how to distinguish its main features?

First, you need to understand how it all started. In 1990, at the European Organization for Nuclear Research in Switzerland (CERN), physicist Tim Berners-Lee created the World Wide Web. The invention enabled a system for sharing information that would first form the basis of the Web. With Lee, it was possible to launch what we know today. Below are the main concepts that define the phases of the evolution of the web and what the next steps are.

Web 1.0

In the 1990s, the so-called Web 1.0 was the first phase of the World Wide Web. To understand it, one must forget the present moment and imagine something simple and static, without any interaction.

“What we had in the 1990s was basically information from a server that was passed on to the recipient, in this case people. The user was not allowed to post anything on the Internet, only to receive it, ”said Vandersilvio da Silva, Professor of Computer Science at Feevale University.

At the time, new technology was seen as a breakthrough, even though the interaction — which is almost non-existent — was one-way. In this situation, forget about sharing pages with buttons, comments, and more. None of them existed.

Roughly, the pages functioned as a kind of frame. There, it was possible to access the running text and navigate through the hyperlinks that led to other pages. The basic point at this point is the content – almost everyone who saw it was the same. The information was always the same for any user.

The main services at the time were sites such as Altavista, DMOZ and Cadê in Brazil, which no longer exist, as well as Hotmail, Google and Yahoo, which are still in their infancy.

With the advancement of server technology and, above all, the speed of the network, they began to create various mechanisms that helped to create the next stage, Web 2.0.

web 2.0

We can take something closer to what we know than Web 2.0. We are not yet linking the current phase to the next phases – Web 3.0 and Web 4.0 – because there is no agreement on when one will start and when the other will end.

The 2000s are on the rise. With that, Web 2.0 gained momentum. This time. Until 2010, according to Silva, we have intense user interaction with the network. From here, things get trickier, and this is where the true content begins! Individuals can comment, share, and interact. To differentiate it from the previous phase, in this phase, the network relationship is marked by the production of user content, not just the server.

All of these characteristics define, of course, social media. From older ones, such as Orkut and Myspace, to older ones like Facebook, Twitter and Instagram. “At the moment, we have the emergence of mobile phones and tablets that have been helpful in social networking applications, such as sharing images, content and information,” added the coordinator of the Applied Graduate Program. Informatics Unisinosen, Rafael Kunst.

It should be noted that access is concentrated in a specific browser, such as Google Chrome, Mozilla Firefox, Microsoft Edge, or any other that is used to access the Internet.

Here, the concentration of information increases. Through algorithms, the network begins to understand what the user needs. What was stored in the files is now counted in the data, an infinite number of them. Data and information are essential to explain the next phases of the network.

Web 3.0

At this stage, the experts are different. One first thought is that the introduction of Web 3.0 is still in full swing. So the next stage, the Web. 4.0 would be just a complement to the previous one, as many of the features are mixed between the two phases. The second line says that Web 3.0 represents the current moment and that the next stage, Web 4.0, is about to begin. But before the discussion, it is necessary to explain 3.0.

An important part of understanding this period is that databases do not focus on specific points, but on blocks organized in strings, on the blockchain. Technology is best known for promoting cryptocurrency.

Kunst explains that the blockchain is divided into three concepts. The first is immutability. That is, no information can be changed. Second, transparency. The information can be viewed by anyone, which proves that this cryptocurrency, for example, is valid. Third and most important: identity. Technology works like a signature, like fingerprints to validate a transaction.

“We’re still on track for 3.0, on a more decentralized path. Basically, here we have the most massive use of virtual reality with the so-called ‘metaverse’. That’s happening from the games, and we’re already seeing it being transplanted to other areas, ”Kunst said.

Professor Unisinos ’view is gaining even more momentum with recent events. October 2021Facebook announced a change to the name “Meta”. The company is one of the first to promise billions of dollars in investments to create a digital universe using the virtual reality (VR) that characterizes it. To explain this, the Direto ao Ponto podcast had a special interview on the subject. you can check by clicking here.

“Of course, it depends on the line of research. In this case, we call Web 3.0 the “Semantic Web” because it becomes more intuitive. A practical example: you are looking for a car that you want to buy on a website. Then, on a different page and without any links, several ads for the same car start appearing. There are algorithms to observe and thus provide the goods that the user is looking for, ”added Vandersilvio da Silva from Feeval.

Divergence is driven by artificial intelligence when Web 3.0 ends and Web 4.0 begins. In addition to the metaverse and algorithm, machines are also increasingly part of the network. Because of this interaction, between man and machine, it is difficult to distinguish between stages. So let’s jump to the next step.

Web 4.0

Defined as the “Symbiotic Web”, this phase enhances the interaction between humans and machines. Due to the high participation of devices in the network, the time is called the “Internet of Things”.

“Since 2010, it has been discovered that there are more‘ things ’connected to the Internet than humans. This Web 4.0 theme is the interaction of humans with machines. The idea of ​​Web 4.0 is to eliminate intermediaries so that the web is less decentralized, “says Silva.

Today, almost every home appliance is connected to the Internet. TVs, refrigerators, cell phones, virtual assistants like Alexa, from Amazon. The list is endless. Interactions between users should also be increased to levels that are not yet idealized.

The main divergence indicated in the previous paragraphs is that the features of Web 4.0 coexist with Web 3.0. This is why Professor Rafael Kunst of Unisinos has argued that the next stage of the internet serves as a complement, not just another phase. “The concept of Web 4.0 already exists and is closely linked to artificial intelligence. In fact, it is part of what we expect for Web 3.0, ”he said.
