The internet was created for sharing information. It is the most significant technological innovation that has ever been created in human history. The internet has transformed lives on so many levels. Looking at 2020 we could see how heavily reliant the world is on the internet. The use of the internet makes our lives easy, fast and connected. Web 1.0 is the first version of the internet, when it first came out websites on web 0.1 were read-only. It was powered by a regular computer and anyone could freely build on it. In 2005 all of these changed with web 2.0 also called social media web as it built connections with people. Users could not only interact with the website but also interact with themselves. Facebook, YouTube, and Twitter were just easier ways for people to create their own Web pages. They are both controlled by big giants and single entities. They have absolute power over everything, even on our data, Cambridge Analytica collected personal data belonging to millions of Facebook users without their consent for political advertising by implementing various forms of psychological targeting. This is where web 3.0 shines, it eliminates the centralized nature of web 2.0 by distributing authority power to everybody.

Differences between Web 2.0 and Web 3.0

Web 2.0 has all users connected to a central authority, hence information propagates quickly, as propagation is handled by a central authority. However, in Web 3.0 the furthest participants on the network may potentially be many edges away from each other. Information broadcast from one side of the network may take a long time to reach the other side.

In the event of conflicting data in Web 2.0, resolution is clear and easy: the ultimate source of truth is the central authority. For Web 3.0, a protocol (often complex) is needed for dispute resolution, if peers make conflicting claims about the state of data which participants are meant to be synchronized on.

Web 2.0 has a single point of failure: malicious actors may be able to take down the network by targeting the central authority. This problem is solved by Web 3.0 by having no single point of failure: network can still function even if a large proportion of participants are attacked/taken out

Podcasts, blogs, and video sites are examples of Web 2.0. AI and ML-powered applications (dApps) such as multi-user virtual environments, 3D portals, and integrated games will be available for Web 3.0.
