# Welcome to EthereumJ for Android

|
|
# About
|
|
EthereumJ is a pure-Java implementation of the Ethereum protocol. For high-level information about Ethereum and its goals, visit [ethereum.org](https://ethereum.org). The [ethereum white paper](https://github.com/ethereum/wiki/wiki/%5BEnglish%5D-White-Paper) provides a complete conceptual overview, and the [yellow paper](http://gavwood.com/Paper.pdf) provides a formal definition of the protocol.

|
|
|
This is an Android-optimized fork of [EthereumJ](https://github.com/ethereum/ethereumj).
|
|
|
|
This repository consists of:
|
|
* [ethereum-core](ethereumj-core): a android compatible library of ethereumj-core .
|
|
* [app]: a simple mockup GUI for exploring Ethereum functionality and usage.
