Web 2.0 vs Web 3.0: Similarities & Differences

Web 3.0, also known as Semantic Web, is the 3rd and the latest iteration of the internet based on blockchain technology. The defining features of Web 3.0 are

• Decentralization – The data is not stored at a single location. Instead, it is distributed across different nodes.
• Trustlessness – Participants can interact directly with each other. No need to trust an intermediary like any particular app or website.
• Permissionless –  Permission from any authority or governing body is not required for participation in Web 3.0
• Artificial Intelligence (AI) –  Computers will understand information just like humans through Semantic Web concepts and natural language processing. 
• Machine Learning (ML) – Computers will utilize data and algorithms to imitate the learning and processing capabilities of humans and will improve their accuracy gradually. 
• Connectivity and Ubiquity – More and more devices will get connected to the internet and to each other. The content and information would be more ubiquitous to be accessed by multiple applications
