Value exchange is the main use case of the Ethereum blockchain today, often via the blockchain’s native token, ether. But many of the developers are working on the cryptocurrency because of its long-term potential and the ambitious vision of its developers to use Ethereum to give users more control of their finances and online data.
This ambitious idea – which sometimes leads to Ethereum being referred to as “world computer” – has been met with its share of critics who say it probably won’t work. But if this experiment rolls out as planned, it would spawn apps very different from Facebook and Google, which users knowingly or unknowingly trust with their data.
