What is Web 3.0? What can we expect from the new generation of internet?

Web 3.0 is a relatively recent term, it is the concept of a third generation of internet – a decentralized network where users have full control over their data, personal information and activities. them on the internet. In this article, let’s look back at the Web 1.0 and 2.0 generations with Tech Town and learn about the concept of Web 3.0 and its potential.

Web 1.0 and Web 2.0

The Internet appeared in 1990, at that time the website was like a tool to transmit information, users would only receive that information passively and could not do anything else. Of course, there is no Web 1.0 concept yet.

In 1999, Darcy DiNucci – Author, web designer and UX expert, was the first to introduce the concept of Web 2.0 (since then, people call websites before Web 2.0 as Web 1.0). A passage from her post reads as follows:

“The web as we know it, which simply downloads images into a static browser window, is only a very small part of the future web. The early signs of Web 2.0 have appeared gradually, and we are only seeing the first steps. The upcoming Web can be understood as the place where the action happens….”

Web 2.0 outperforms Web 1.0 in the ability to interact between users and websites. Users can operate on the website such as registering an account, selecting content, uploading images, videos, etc. Technically, the advancement of Web 2.0 lies in its ability to separate the requirements of users. The user sends to the server system and responds with separate data for each request. That saves users from having to reload the entire website to perform a certain action.

What is Web 3.0?

Human needs are always increasing. In the context of the internet being widely disseminated, Web 2.0 is no longer enough to meet the requirements of users at this time. Not only do they need to interact with the website, they also need to be as quick and convenient as possible without even having to do much.

And the solution has appeared, it refers to the standardization of websites to help unified data, making data exchange faster and easier.

The Semantic Web is a movement led by the World Wide Web Consortium (W3C) to standardize common data formats on the Internet to address the problems of Web 2.0. This movement encourages websites to publish content that is semantically inclusive, with the goal of converting unstructured, or semi-structured content into valuable “web data.” This Semantic Web movement is known as Web 3.0. The result will be smart, connected and integrated websites.

Of course, in order for both users and machines to be able to interact with data, programs must understand the data, understand the semantics and context of a document. With this in mind, Web 3.0 can be developed based on two bases, Semantic Web and Artificial Intelligence (AI).

What does Web 3.0 and Blockchain have to do with each other?  

The Semantic Web has yet to solve one of the Internet’s most pressing problems, data theft. Users today still cannot protect their data, nor can the original value of the data be preserved. The data architecture of the internet for 30 years now is all stored on independent computers, not a network, which makes it impossible for users to control their data since it is sent, they will be very frustrated. It’s hard to know what their data will be used for. In this day and age, your personal data is the most valuable thing on the internet. You can see the growth of Google or Facebook, because they have the personal data of billions of users, it is proportional to their expansion and growth.

In that situation, blockchain technology was an impetus for developers to create the next generation of internet – Web 3.0. More specifically, blockchain changes the way data is stored and managed. Users can exchange data without intermediaries, can know the journey of data on the common network, protect data as well as its value. The foundation of websites operated according to this model is called the decentralized Web 3.0 platform.

Note that what we are talking about above is not a definition of Web 3.0, in fact it does not have a completely accurate definition. Semantic Web or Decentralized Web are just development directions that many people think will be the next generation of web.

What technologies will Web 3.0 use?

Web 3.0 will be the result of the combination of current web technologies along with advanced technologies such as Blockchain, AI. It will be an upgrade from its predecessors Web 1.0 and 2.0. We will go through the technology platforms of Web 1.0, 2.0 and then Web 3.0.

●     Web 1.0: Also known as the Static Web, it was the first reliable internet in the 1990s. It gave users access to information, and nothing more. Web 1.0 does not have an algorithm to filter information, so users will have difficulty finding relevant information. Furthermore, the content is only created by a handful of authority figures.

●     Web 2.0: Thanks to advances in web technologies such as Javascript, HTML5, CSS3,… Social networks have appeared and shaped the concept of Web 2.0. Startups have built interactive web platforms like Facebook, Youtube, Wikipedia and many more. And of course, the feature of social networks is that users can self-produce content and distribute it on many different platforms.

●     Web 3.0 (not yet released): This will be the next stage of the internet, applying AI and machine learning technologies – the internet will become smarter, able to process information with near intelligence like humans, can support, meet the unique needs of each person, deliver relevant content directly to every internet user.

Typical Features of Web 3.0

Ubiquity (popularity)

Ubiquity means the internet will be ubiquitous. Web 2.0 is already ubiquitous, making it possible for anyone to access the internet if they have a smartphone or computer. Web 3.0 will take this one step further, not only focusing on smartphones or computers but also being able to connect to things with IoT technology. It can be said that in the future there will be countless new smart devices appearing.

Semantic Web

Semantic is the study of the relationship between words, the Semantic Web allows computers to analyze a multitude of content, transactions and connections between people. From there, the internet can understand user semantics and emotions by analyzing data, users will have a better internet experience thanks to enhanced association in data.

Artificial intelligence

Wikipedia defines AI as intelligence demonstrated by machines. As the Semantic Web analysis above, Web 3.0 can read – understand emotions, so it will create intelligent machines. Web 2.0 can also do this, but it is more subjective because it is done by humans, it creates opportunities for misconduct such as bias, fraud,… Web 3.0 is based on AI , so as AI advances, it will provide users with the best filtered data without bias.

Spatial Web (Spatial Web) and 3D Graphics

There are some who think that Web 3.0 will blur the line between digital and reality, they call it the Spatial Web. With the advancement of graphics technology, a three-dimensional virtual world or 3D graphics has appeared and contributed to shaping Web 3.0. Superior to 2D, 3D graphics for a deeper “immersive” experience, it can be applied in many fields such as real estate, healthcare, e-commerce, …

Web Application 3.0

People set the standard for Web 3.0 to be smart and give users exactly what they need. Several companies such as Amazon, Apple, and Google have built or converted their products into internet 3.0 applications. It’s important to note that these applications are still in their early stages, which means there’s still a lot of room for improvement, and Web 3.0 may indeed be far from what it is today. We will talk about two famous applications using Web 3.0 technology today, Siri and Wolfram Alpha.


Apple’s voice-controlled AI assistant (Siri) is getting smarter by the day. It uses voice recognition, combined with AI to execute complex commands from different users.

Today, Siri and other AI assistants like Amazon’s Alexa and Samsung’s Bixby can understand requests like “where’s the nearest burger joint” or “make an appointment with Sasha Marshall for 8 a.m. tomorrow.” ” and immediately provide appropriate information or action.

Wolfram Alpha

Wolfram Alpha is a “computational knowledge engine” that answers your questions directly with computation. Unlike Google, it does not provide a search command with a series of web pages, but will provide full information including metrics, detailed descriptions or even history of a certain issue. That is the difference between Web 2.0 and Web 3.0.

The immediate disadvantages of Web 3.0

Slow speed

The decentralized internet is more secure and error-proof, but it also has a slower speed due to the need to run validating nodes.

Not New User Friendly

Currently, most decentralized technologies are not user-friendly. They must have a certain understanding of blockchain to be able to use it.

The transition from the traditional web to the decentralized web cannot be a “leapfrog”, it will have to happen from the traditional web → partially decentralized web → fully decentralized, that facilitates for users to adapt.

The internet of the future may be decentralized, but that doesn’t mean centralized systems have to be eliminated altogether, because they’re still essential.

Lots of junk data

The data on the blockchain is forever, which makes the blockchain heavier and heavier. Moreover, Blockchain technology requires each node to download all Blockchain data, making the total capacity of Blockchain on the entire network even more terrible. Take Ethereum’s Blockchain for example, which reached 300 Gigabytes in size on September 19.

Ability of extension

The security of a decentralized system is both a strength and a weakness, it cannot be arbitrarily scaled like a centralized system. The early blockchains of Bitcoin or Ethereum had extremely poor scalability, so these blockchain systems were frequently congested. This is a big problem that Web 3.0 needs to solve before it becomes a reality and becomes widespread.

Advantages of Web 3.0

No middleman needed

Since on a decentralized network, all data is transacted and exchanged directly without having to depend on a third party like Facebook or Paypal, which greatly reduces transaction costs.

Prevent data breaches.

The data on a decentralized network is controlled by the users themselves, so it is very difficult for hackers to attack, unless he has the ability to control the entire network. Companies like Google or Facebook will also find ways to effectively use your data to generate revenue, they won’t sell it to third parties for profit.

Data never disappears

Your favorite videos, or even your important chats, won’t disappear on Web 3.0 until the internet stops working. Because no one has access to them and delete them.

Service 24/7

Services on Web 3.0 are not managed by a fixed server, the services will always be up and running as long as the internet is up. Your work will never be interrupted midway because of power failure or server attack.

Smart connection

Web 3.0’s semantic tagging makes the internet smarter and more connected. Users can use semantically tagged internet-connected devices to provide a more relevant, intuitive and personalized website experience. It is the result of the combination of IoT and AI technology.


We won’t be sure when Web 3.0 will be widely used. But we have the right to put our trust in a new internet – where everyone has the right to own and manage their own data, then big companies like Facebook or Google will have to pay for their personal data. we.
