notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf

[![Build Status](https://travis-ci.org/bitcoinj/bitcoinj.png?branch=master)](https://travis-ci.org/bitcoinj/bitcoinj) [![Coverage Status](https://coveralls.io/repos/bitcoinj/bitcoinj/badge.png?branch=master)](https://coveralls.io/r/bitcoinj/bitcoinj?branch=master)
[![Visit our IRC channel](https://kiwiirc.com/buttons/irc.freenode.net/bitcoinj.png)](https://kiwiirc.com/client/irc.freenode.net/bitcoinj)
### Welcome to bitcoinj
The bitcoinj library is a Java implementation of the Bitcoin protocol, which allows it to maintain a wallet and send/receive transactions without needing a local copy of Bitcoin Core. It comes with full documentation and some example apps showing how to use it.
### Technologies
* Java 6 for the core modules, Java 8 for everything else
* [Maven 3+](http://maven.apache.org) - for building the project
* [Orchid](https://github.com/subgraph/Orchid) - for secure communications over [TOR](https://www.torproject.org)
* [Google Protocol Buffers](https://github.com/google/protobuf) - for use with serialization and hardware communications
### Getting started
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.
#### Building from the command line
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.
#### Building from an IDE
Alternatively, just import the project using your IDE. [IntelliJ](http://www.jetbrains.com/idea/download/) 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.
### Example applications
These are found in the `examples` module.
#### Forwarding service
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.
### Where next?
Now you are ready to [follow the tutorial](https://bitcoinj.github.io/getting-started).
