UPSC Prelims 2022 Question:

With reference to Web 3-0, consider the following statements:

1. Web 3.0 technology enables people to control their own data.
2. In Web 3.0 world, there can be blockchain based social networks.
3. Web 3.0 is operated by users collectively rather than a corporation.
   
   

Which of the statements given above are correct?

Explanation: 

Web 3.0 represents the next iteration or phase of the evolution of the web/internet and potentially could be as disruptive and represent as big a paradigm shift as Web 2.0 did. Web 3.0 is built upon the core concepts of decentralization, openness, and greater user utility.

Features of Web3.0 

• Decentralization is a core tenet of Web 3.0. In Web 2.0, computers use HTTP in the form of unique web addresses to find information, which is stored at a fixed location, generally on a single server. With Web 3.0, because information would be found based on its content, it could be stored in multiple locations simultaneously and hence be decentralized. This would break down the massive databases currently held by internet giants like Meta and Google and would hand greater control to users.With Web 3.0, the data generated by disparate and increasingly powerful computing resources, including mobile phones, desktops, appliances, vehicles, and sensors, will be sold by users through decentralized data networks, ensuring that users retain ownership control. So, statements 1 and 3 are correct.
• In addition to decentralization and being based upon open-source software, Web 3.0 will allow participants to interact directly without going through a trusted intermediary and anyone can participate without authorization from a governing body. As a result, Web 3.0 applications will run on blockchains or decentralized peer-to-peer networks. So, statement 2 is correct.
  
  

Therefore, option (4) is the correct answer.
