Web 3.0 (Web3) is the third generation of the evolution of web technologies. The web, also known as the World Wide Web, is the foundational layer for how the internet is used, providing website and application services.

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.
