Web 5.0

  • Web 1.0 - It is a read-only Internet made of static web-pages.
  • Web 2.0 – It is a read and write Internet. Users were able to communicate with servers and other users leading to the creation of the social web. This is the World Wide Web that we use today.
  • It is more centralised and focused on user-created content. Eg Use of Facebook.
  • Web 3.0 is an evolving term.  It refers to the next generation “read-write-execute” Internet with decentralization as its bedrock.
  • It leverages the use of block chain technology where people can interact with each other without the need of an intermediary.
  • Web 3.0 will be driven by Artificial Intelligence and machine learning where machines will be able to interpret information like humans.
  • Web 5.0 is Web 2.0 plus Web 3.0 that will allow users to ‘own their identity’ on the Internet and ‘control their data’.
  • It is being developed by former Twitter CEO Jack Dorsey's Bitcoin business unit, The Block Head.
  • It aims at building an extra decentralized web that puts you in control of your data and identity.
  • It is built with an aim to return “ownership of data and identity to individuals”.
  • Difference between Web 3.0 and Web 5.0 – Both Web 3.0 and Web 5.0 envision an Internet without censorship from governments or big tech.

  • Eg: Bob is a music lover. He hates his personal data locked to a single vendor. Now Bob can keep this data in his decentralized web node and grant any music app access to his settings and preferences. He not need create a profile in every music app.  This makes him control his data as well as his identity.
