The key features of web 3.0 are:
  1. Open – It’s ‘open' in the sense that it’s made with open-source software developed by an open and available community of developers and accomplished in full view of the public.
  2. Trustless – The network offers freedom to users to interact publicly and privately without an intermediary exposing them to risks, hence “trustless” data.
  3. Permissionless – Anyone, including users and providers, can engage without the need for permission from a controlling organization.
  4. Ubiquitous – Web 3.0 will make the Internet available to all of us, at any time and from any location. At some point, Internet-connected devices will no longer be limited to computers and smartphones, as they are in web 2.0. Because of the IoT (Internet of Things), technology will enable the development of a multitude of new types of intelligent gadgets.
