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. The ethereum white paper provides a complete conceptual overview, and the yellow paper provides a formal definition of the protocol.
This is an Android-optimized fork of EthereumJ.
This repository consists of:
- ethereum-core: a android compatible library of ethereumj-core .
- [app]: a simple mockup GUI for exploring Ethereum functionality and usage.
