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.
The Ethereum protocol is under heavy development, thus so is this implementation. See the [todo list](TODO.md), GitHub [Issues](https://github.com/ethereum/ethereumj/issues) and [milestone schedule](https://github.com/ethereum/ethereumj/milestones). Issues are prioritized using [waffle](http://waffle.io/ethereum/ethereumj).
For complete details on downloading, building and using [etherumj-core](ethereumj-core) and [ethereumj-studio](ethereumj-studio), see their respective readme files.
