What is Web 3.0?
In one sentence, Web 3.0 is a more user-centric, transparent, and secure Internet that focuses on humanity.

Before introducing Web 3.0, we might as well review Web 1.0 and 2.0
Web 1.0: The beginning fo everything
Have you ever heard that for a dial-up connection and to download a 5MB file can take up to 200 years?
At that time, people mainly used Internet to maintain basic communication, and the use of Internet could only be seen in the offices of large companies. Compared with now, the number of websites were very small.
Yes, things were not so good at the time, but this was the beginning of a new era of civilization. We call it the Internet Web 1.0.
Web 1.0 is one-way.
Large companies create content for people to read, with almost no interactions, users could only read data, and only content creators could edit and create contents. So, just like reading a book in a library, users didn’t have much rights, they were just consumers.
Later, plagiarism appeared. People started copying contents and pasting them on their website. Original contents were very rare.
Web 2.0: Social Revolution
When Web 2.0 appeared, end users benefited a lot. Users could write and read data, and people have realized that there were serious limitations in a framework that can only handle one million users.
Web 2.0 could handle billions of users based on Ajax and JavaScript frameworks, and blogs replaced boring static web content.
Web 2.0 also introduced video streaming and online games, everything went online. Websites were interactive and more dynamic, and online stores have begun to rule the world economy.
You can say that it was a real revolution, and the introduction of Web applications has opened up new horizons.
Web 3.0: The Internet of the Future

1. The Internet of Everything
Looking around, we now have smart refrigerators, smart TVs, smart scales, and home assistants.
All these things can be connected to Internet, and they form a network of devices called the Internet of Things (IoT).
The Internet of Things is one of the biggest features of Web 3.0, the purpose is to connect everything to Internet. Currently, not all devices can be connected, right now we do not have this kind of infrastructure, but with the development of 5G, this goal will be achieved in the near future.
2. User-centric
The Web 3.0 blockchain DApps are more user-centric. It will exclude middlemen. We don’t have to rely on huge data servers controlled by private companies. Our personal data will be more secure and private. Since there is no centralized server, all data will be spread between devices, and people can access them freely. It will create a more humane Internet world.
3. Artificial intelligence
Artificial intelligence will mainly focus on providing people with better analysis and results. In fact, technology giants are already carrying out their AI projects. For example, artificial intelligence will try to recommend music that suits your taste.
In addition, you will find that when you search for a specific product on Google, the ads on your Facebook page will also change, and everything is interrelated. Therefore, the future marketing strategy will no longer use large-scale marketing techniques, but people-oriented.
4. Semantic Web
The blockchain technology stack proposes a topic called the Semantic Web. The Semantic Web means a way to understand web content, just like human behavior, it is associated with machine learning and artificial intelligence, trying to teach computers to understand data and how it behaves. In semantic search, search results will be more accurate and relevant. Web 2.0 relies on keywords, page permissions, and domain permissions to rank content, but Web 3 browsers try to understand Web content like people do.
5. The future of 3D graphics and content
There is no doubt that web content is more graphic nowadays, and people like to see and share videos and images instead of simple text. In the near future, augmented reality (AR) and virtual reality (VR) will become popular, and different applications and games will have more realistic graphics and feelings.
In addition, 3D printing is not limited to laboratory use. People will use 3D printing more and it will become more user-friendly and cheaper.
Web 3.0 will reinvent our Internet world, and more possibilities are still beyond imagination.
