Ethereum

Unlike Bitcoin, Ethereum focuses not as much on digital currency as it does on decentralized applications (phone apps). You could think of Ethereum as an app store.

The platform is looking to return control of apps to its original creators, and take away that control from middlemen (like Apple, for instance).

The only person who can make changes to the app would be the original creator. The token used here is called Ether, which is used as currency by app developers and users.
