Ethereum is a cryptocurrency with a smart contract platform. The currency is called Ether. Ethereum was launched by Vitalik Buterin in the summer of 2015.
Ethereum was initially described by Buterin in late 2013, formally described by Gavin Wood in early 2014 in a so-called "yellow paper" and launched by Buterin 30 July 2015. It has been described as being a "next generation" (or "Bitcoin 2.0") platform.

The currency unit of the Ethereum platform is called Ether, used to pay for computational services on the network.
To finance development, Ethereum distributed the initial allocation of Ether via a 42-day public crowdsale, netting 31,591 bitcoins, worth $18,439,086 at that time, in exchange for about 60,102,216 Ether.
Contracts
Smart contracts are programs and protocols to facilitate the automated performance of a contract. Ethereum contracts can be implemented in various languages, compiled into bytecode for the Ethereum Virtual Machine before being deployed to the blockchain.
Every contract is run on every full Ethereum node simultaneously and the result is the consensus of the output. The documentation notes that computation on the EVM is "very expensive" and that "you will not be able to do anything on the EVM that you cannot do on a smartphone from 1999."
Implementations
The following full-node implementations of Ethereum are available:
- Geth, written in Go
- Parity, written in Rust
- Eth, written in C++
- Ethereum J, written in Java
- pyethapp, written in Python
- ethereumjs, written in JavaScript
- ethereumH, written in Haskell
