where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
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.

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
of any other Contributor, and only if You agree to indemnify,

To get started, ensure you have the latest JDK installed and then just run "ant".
- A JAR will be placed in dist/
- JavaDocs will be placed in docs/
- Unit tests will be run
Now ensure you're running a BitCoin node locally and run the example app:
cd out
It will print a BitCoin address. If you send coins to it, you should get them back a few minutes later when a block is solved.

Here is a brief list of things that still need to be done.
More unit tests:
- Implement more unit tests for block chain functionality
- Create a MockNetworkConnection and use it to test the Peer.
- Properly support multiple chains
- Start up faster
- Store a block locator in the wallet
- Parse the stored headers at startup, then download the rest
- Provide a seed node list in the NetworkParameters.
- Implement tx fees.
- Support import of private keys and then extracting its transactions from the block chain.
- Longer term potentially add a getmerklebranch protocol command so we can check 0-confirmation transactions.
- Implement a simple Swing GUI payment app.
- Find a way to avoid some horrid hacks when shutting down the network connection.
- Implement a BitCoin class that encapsulates a BigInteger and formatting.
- Make NetworkParameters use subclasses instead of static methods to construct.
