In Web 1.0, content was created by a few people, the website owners. This content could be consumed by users, interaction, e.g. in the form of comments or sharing the content, was usually not possible. The owner of a website was responsible for publishing and updating content on the HTML pages.
Web 2.0 is the logical development of Web 1.0. In today's Internet, users can create content themselves and interact with the content on pages: They can write posts on social networks themselves as well as like, share and comment on them. Because of these interaction possibilities, Web 2.0 is also called the social web. However, networking between different platforms is only partially possible so far. Web 2.0 does not exactly score points for its strong ethics. The users' data is stored on a few large servers to which hardly anyone has access. The algorithms on which the platforms are based are usually not visible and therefore not transparent. Neither the legislator nor internet collectives can understand how they work and inform users accordingly or take action to protect them.
Web 3.0 or simply »Web 3« wants to improve many things that were suboptimal in the old web versions. The developers of Web 3 platforms want to give users back control over the internet and their data. To this end, platforms like the Metaverse are built on blockchain. All information is stored in chronological order, can be seen by everyone and can hardly be manipulated. This decentralised version of the internet will no longer be stored on a few servers but piece by piece on the computers of private individuals. In addition, we will use Web 3 less via screens (smartphone, laptop). Instead, wearables such as AR and VR glasses will become more widespread to immerse us in the metaverse and connect us with digital worlds.
