What is Web 3.0 and what are we at?

Web 1.0, 2.0, 3.0 and 4.0. Experts are still working to define what they mean, although there is still no clear indication of when the start and end will take place. But how different is its main feature?

First, you need to understand how things started. In 1990, at the European Organization for Nuclear Research (CERN) in Switzerland, physicist Tim Berners-Lee created the World Wide Web. The invention enabled an information sharing system that would be the basis of the original Web. With Lee, he can start what we know today. Below, the key points that define the stages of evolution of the site and what are the next steps.

Web 1.0

In the 1990s, what was known as Web 1.0 was the first phase of the World Wide Web. To understand it, it is necessary to forget the present moment and think of something simple and static, without distractions.

“What we have in the 1990s was data from a server that was sent to a recipient, in this case, a human. The user was not allowed to post anything on the Internet, except to accept it only “, explains Vandersilvio da Silva, professor of Computer Science courses at Feevale University.

At the time, new technologies were considered a precursor, although interactions – something impossible – were one way. In this case, forget about the page with lots of buttons, comments and all. None of that happened.

Roughly speaking, the pages work like a kind of system. In it, it can access text and track hyperlinks that lead to other pages. The main theme of this period is related to the theme – practice, the same can be seen by everyone who enters. The information is always the same for all users.

The main services of this period are sites such as Altavista, DMOZ and Brazilian Cadê – which no longer exist -, in addition to the embryonic Hotmail, Google and Yahoo, which still follow.

With the advancement of technology and, more importantly, the speed of the network, more and more technologies are emerging that help develop the next level, Web 2.0.

web 2.0

Web 2.0 can be considered as something close to what we know. We will not be connecting the current phase with the next phase – Web 3.0 and Web 4.0 – because there is no consensus when one starts and the other ends.

The 2000s are on the rise. With it, Web 2.0 gets stronger. This time. until 2010, according to da Silva, we have integrated users with the network. From now on, it is possible to get content and also create. People can comment, share and discuss. To be different from the previous level, at this stage, online relationships are marked by the creation of user content, not just the server.

All of these characteristics, of course, define relationships. From the older ones, like Orkut and Myspace, to the most current ones, like Facebook, Twitter and Instagram. “Currently, we have the emergence of smartphones and tablets, and mobile devices that, naturally, have helped in social applications, such as sharing photos, points and information “, completed the staff of the Graduate Program in Applied. Count of Unisinos, Rafael Kunst.

It is important to note that access is focused on a specific browser, such as Google Chrome, Mozilla Firefox, Microsoft Edge, or any other device used to access the Internet.

Here, the concentration of the data increases. Through algorithms, the network begins to understand what the user wants. What used to be stored in the file is now included in the file – there is no end to them. Data and information are very important for describing the next phase of the network.

Web 3.0

At this stage, the experts are different. The first line of thinking is that access to Web 3.0 is still being finalized. So the next step, the Web. 4.0, will only be an addition to the previous one, since many features of the two stages are confused. The second line argues that Web 3.0 represents the present and the next phase, Web 4.0, will begin. But, before arguing, it should be explained 3.0.

An important aspect of understanding at this time is that the data is not focused on certain concepts, but on blocks created in chains, blockchain. Most technologies are known for supporting cryptocurrencies.

Kunst explains that the blockchain is divided into three main sections. The first is immutability. That is, no data can be changed. Second, transparency. The data can be verified by anyone, which proves that cryptocurrency, for example, is valid. Third and most important: personal. Technology works like a signature, like a finger to identify changes.

“We’re still on the way to 3.0, one way or the other. Basically, we have here the biggest implementation of virtual reality with the so-called ‘metaverse’. of the game, and we’ve seen it move to another location ”, pointed out Kunst.

Unisinos teacher’s vision has gained more momentum with recent events. October 2021Facebook announces name change to “Meta”. The company is one of the first to promise to invest millions of dollars in creating a digital world using Virtual Reality (VR), a key metaverse symbol. To explain, Direto ao Ponto podcast has done a special interview on the topic. you can check click 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 good example: you find the car you want to buy. Then, on different pages and without links, multiple ads for the same traffic start appearing. There are algorithms there to monitor and, therefore, provide users stuff he is looking for “, added Vandersilvio da Silva, from Feevale.

The difference between when Web 3.0 ends and Web 4.0 begins is brought to life by intelligence. In addition to the metaverse and the algorithm, the machines are also part of the network. It is because of this impact, man and machine, that it is difficult to differentiate between stages. So we jump to the next step.

Web 4.0

Translated as “Symbiotic Web”, it is at this stage that human-machine interactions exacerbate. Due to the heavy integration of network devices, the term has become known as “internet of things”.

“As of 2010, it has been observed that there are more” connected “devices connected to the Internet than humans. The Web 4.0 issue is the impact of human interaction with technology. of the decision of the removal of the middleman, making the site unaffected “, argues da Silva.

Like all home appliances today are connected to the internet. TVs, refrigerators, cell phones, virtual assistants like Alexa, by Amazon. The names have no end. Interaction between users should be raised to levels that have not yet been approved.

The big difference was pointed out in the previous paragraph is that the features of Web 4.0 coexist with Web 3.0. So, as protected by Professor Rafael Kunst, from Unisinos, the next phase of the internet is more work, and not another phase. “The concept of Web 4.0 already exists and is close to the level of intellectual property. It, in fact, seems like part of what we need for Web 3.0”, he added.
