What Are Web 2.0 and Web 3.0?

What Are Web 2.0 and Web 3.0?
 Web 2.0 and Web 3.0 refer to successive iterations of the web, compared with the original Web 1.0 of the 1990s and early 2000s. Web 2.0 is the current version of the internet (a term often used interchangeably with the web) with which we are all familiar. Web 3.0 or Web3 is the third generation of the World Wide Web. Currently a work in progress, it is a vision of a decentralized and open Web with greater utility for its users. Web refers to the World Wide Web (WWW), the internet’s core information retrieval system. The WWW initialism used to (and often still does) preface a web address and was one of the first characters typed into a web browser when searching for a specific resource online. Internet pioneer Tim Berners-Lee is credited with coining the term World Wide Web to refer to the global web of information and resources interconnected through hypertext links.

Web 3.0 is still evolving and being defined, and as such, there isn't a canonical, universally accepted definition. What is clear, though, is that Web 3.0 will have a strong emphasis on decentralized applications and make extensive use of blockchain-based technologies. Web 3.0 will also make use of machine learning and artificial intelligence (AI) to help empower more intelligent and adaptive applications.

Another aspect that is part of the emerging definition of Web 3.0 is the notion of a semantic web. Among those that have advocated for the integration of semantic technology into the web is the creator of the web, Tim Berners-Lee.

It took over 10 years to transition from the original web, Web 1.0, to Web 2.0, and it is expected to take just as long, if not longer, to fully implement and reshape the web with Web 3.0.

If the trend of change is traced from Web 1.0, a static information provider where people read websites but rarely interacted with them, to Web 2.0, an interactive and social web enabling collaboration between users, then it can be assumed that Web 3.0 will change both how websites are made and how people interact with them.
