The third iteration of the World Wide Web is commonly referred to as Web 3.0. It's a work in progress but a vision of a more user-friendly, decentralized, and open web. Decentralized data networks will be used in Web 3.0 to facilitate the sale of user-generated data generated by a wide variety of computing resources such as mobile phones, desktop computers, appliances, vehicles, and sensors. This will guarantee that users maintain ownership over their data. Most Web 2.0 applications are used for social media, streaming media, and online shopping, but Web 3.0 can provide users with much more. Features central to Web 3.0, such as the Semantic Web, artificial intelligence, and machine learning, have the potential to greatly expand the platform's reach and the quality of the user experience.
