The bitcoinj.cash library will be following the Bitcoin SV chain. The following changes will take place:
- a minor update, including released jar, to update DNS seeds to point to Bitcoin SV DNS seeds
- rebranding to bitcoinj-sv version 0.9.0
- work will start on bitcoinj-sv version 1.0.0, which will make significant changes to the API
The bitcoinj.cash library is a Java implementation of the Bitcoin cash protocol. This library is a fork of Mike Hearn's original bitcoinj library aimed at supporting the 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
- Maven 3+ - 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 Maven 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
mvn clean package
You can also run
mvn site:site
to generate a website with useful information like JavaDocs.
The outputs are under the target
directory.
Alternatively, just import the project using your IDE. IntelliJ has Maven integration built-in and has a free Community Edition. Simply use File | Import Project
and locate the pom.xml
in the root of the cloned project source tree.
These are found in the examples
module.
This will download the block chain and eventually print a Bitcoin address that it has generated.
If you send coins to that address, it will forward them on to the address you specified.
cd examples
mvn exec:java -Dexec.mainClass=org.bitcoinj.examples.ForwardingService -Dexec.args="<insert a bitcoin address here>"
Note that this example app does not use checkpointing, so the initial chain sync will be pretty slow. You can make an app that starts up and does the initial sync much faster by including a checkpoints file; see the documentation for more info on this technique.
Now you are ready to follow the tutorial.
