What is Web 3.0? Explore the new era of the Internet 

The Web world has seen great change over the past three decades. A lot has happened since the early days of Web 1.0, when the internet was essentially a medium for text-based information exchange. And now, when Web 3.0 appears, it has created a new wave. Many people often say that this is the future of the Internet. So what is Web 3.0 exactly? Let’s find out through the article below. 

I. What is Web 3.0? 

1. Web 1.0 

In the mid-1990s, the advent of web browsers like Netscape Navigator ushered in the Web 1.0 era. This early version of the Internet was called the “static web”. It is a read-only website and lacks many interactive features. 

2. Web 2.0 

Web 2.0 refers to a paradigm shift in the way the Internet is used. The great innovation in this era is the emergence of social networks (Facebook, Youtube, …) and smartphones (Iphone). 

3. Web 3.0 

Web 3.0 is a new breakthrough in the development of the Internet. It will use AI, machine learning and B to provide users with smart applications.

If web 1.0 is read-only web, web 2.0 is read-write web, then web 3.0 is read-write-interactive web. People can read, write, and interact with content, including 3D graphics, on websites and apps. 

II. Main characteristics 

  • Semantic web:

The content of the web is displayed based on the effective analysis of the meaning of words 

  • Decentralized:

Information can be simultaneously stored in multiple locations. This makes it decentralized. So information will be found based on its content instead of a single location 

  • Connectivity and Dissemination:

Information and content are more connected and more common. They are accessed by many applications and increasingly devices are connected to the internet 

  • Artificial intelligence (AI) and machine learning:

Web 3.0 will allow computers to understand information similar to humans. Web3 will also use machine learning – a branch of AI that uses data and algorithms to mimic human learning, gradually improving its accuracy
