This library is a fork of Mike Hearn's original bitcoinj library aimed at supporting the Bitcoin and Bitcoin Cash eco-system.
It allows maintaining a wallet and sending/receiving transactions without needing a full blockchain node. It comes with full documentation and some example apps showing how to use it.
Release notes are here.
- Java 7 for the core modules, Java 8 for everything else
- Gradle 3.4+ - for building the project
- Google Protocol Buffers - for use with serialization and hardware communications
To get started, it is best to have the latest JDK and Gradle installed. The HEAD of the master branch contains the latest development code and various production releases are provided on feature branches.
To perform a full build use
gradle clean build
To generate a jar bundle use
gradle clean fatJar
You can also run
gradle javadoc
to generate the JavaDocs.
The outputs are under the build directory.
Alternatively, just import the project using your IDE. IntelliJ has Gradle integration built-in and has a free Community Edition. Simply use File | New | Project from Existing Sources and locate the build.gradle in the root of the cloned project source tree.
These are found in the examples module.
Now you are ready to follow the tutorial.
