# Ethereum

From ArchWiki

The Ethereum Project provides an open-source, distributed, blockchain-based platform for so-called wikipedia:Smart contracts.

## Clients

This article or section needs expansion.

Reason: Note several implementations exist in non-/AUR packages, configuration, tips, troubleshooting etc. (Discuss in Talk:Ethereum#)

### Go Ethereum

Go Ethereum, the official Go implementation of the Ethereum protocol, is available as the go-ethereum package.

Create an account with `geth account new`.

The client can be started with `geth`, and it will proceed to download several gigabytes of blockchain data. This will take a very long time. This time can be shortened with

    $ geth --fast --cache=1024

Higher cache values appear to speed up the process more[1].

Optionally, start the client with `geth console` to get a JavaScript console for more meaningful interaction. This console can then be attached-to from another terminal or remotely with `geth attach [hostname:port defaults to localhost]`.

To check balances in the console or attach modes, use `web3.fromWei(eth.getBalance(eth.coinbase), "ether")`.

To start CPU mining, use `geth --mine`. This is far less efficient than GPU mining, and ethereum.org does not recommend it.

#### GPU Mining with geth

This article or section needs expansion.

Reason: There is a way to make a 3rd party Ethereum miner work with geth. (Discuss in Talk:Ethereum#)

GPU mining with geth has been discontinued.

### Ethereum Wallet

You can install the Ethereum Wallet via the mistAUR package or the GitHub releases. Mist will connect to a running geth instance or start its own if it cannot find one.

If you use a GitHub release, download the most recent Linux one with the zip extension: `Ethereum-Wallet-linux64-version.zip`; unzip the file and run `./ethereumwallet`.

If the application fails to start with `error while loading shared libraries: libgtk-x11-2.0.so: cannot open shared object file: No such file or directory`, install the GTK+ 2 library.

The wallet also implements an Ethereum node.
