Concept
Web3 in one sentence
Web3 is the idea of a more open internet with no central owners. Instead of your information being in the hands of a few companies, the proposal is that you own what is yours.
This is possible thanks to blockchain, the same technology behind cryptocurrencies. It’s an evolving technology, so a lot is still being built.
The three phases of the internet
The simplest way to understand Web3 is to see where it comes from.
Web2 · read and write
Today’s internet. Everyone creates and publishes, but big platforms keep the data and control.
Web3 · read, write and own
The new proposal: besides creating, you own your data and assets, without relying on a central intermediary.
The internet of ownership
The big change with Web3 is who holds the control: you, not the platform.
