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.
It is designed in a way that anyone in the world can access and write to. This machine is not owned by a single entity. It is owned collectively by everyone in the network. One can write data on an Ethereum blockchain but cannot update existing data.
The network offers freedom to users to interact publicly and privately without an intermediary exposing them to risks, hence “trustless” data.
People control their own data.
