Questions tagged [ether]

Ether is the currency used in Ethereum blockchain technology. Refer: https://ethereum.org/ether Questions about Ether which aren't about programming should be asked on the dedicated Ethereum site: https://ethereum.stackexchange.com. Questions which are about programming can be asked on either site.

Ether is a necessary element — a fuel — for operating the distributed application platform . It is a form of payment made by the clients of the platform to the machines executing the requested operations. To put it another way, Ether is the incentive ensuring that developers write quality applications (wasteful code costs more), and that the network remains healthy (people are compensated for their contributed resources).

The official website of is Ethereum.org.

There's also a Ethereum StackExchange site that's dedicated to Bitcoin.
