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.

The official website of is Ethereum.org.

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