About

ethereumj is a pure-Java implementation of the Ethereum protocol. For high-level information about Ethereum and its goals, visit ethereum.org. The ethereum white paper provides a complete conceptual overview, and the yellow paper provides a formal definition of the protocol.

This repository consists of:

ethereum-core: a library suitable for inclusion in any JVM-based project.
ethereum-studio: a simple GUI for exploring Ethereum functionality and usage of the ethereumj API.

To see ethereum-studio in action, watch this video.

Todo

The Ethereum protocol is under heavy development, thus so is this implementation. See the todo list, GitHub Issues and milestone schedule. Issues are prioritized using waffle.
