What is Xcoin?
|
|
----------------
|
|
|
|
Xcoin is a lite version of Bitcoin using scrypt as a proof-of-work algorithm.
|
|
- 2.5 minute block targets
|
|
- subsidy halves in 840k blocks (~4 years)
|
|
- ~84 million total coins
|
|
|
|
The rest is the same as Bitcoin.
|
|
- 50 coins per block
|
|
- 2016 blocks to retarget difficulty
|
|
|
|
For more information, as well as an immediately useable, binary version of
|
|
the Xcoin client sofware, see http://www.xcoin.org.

Development process
|
|
-------------------
|
|
|
|
Developers work in their own trees, then submit pull requests when they think
|
|
their feature or bug fix is ready.
|
|
|
|
If it is a simple/trivial/non-controversial change, then one of the Xcoin
|
|
development team members simply pulls it.
|
|
|
|
If it is a *more complicated or potentially controversial* change, then the patch
|
|
submitter will be asked to start a discussion (if they haven't already) on the
|
|
[mailing list](http://sourceforge.net/mailarchive/forum.php?forum_name=bitcoin-development).
|
|
|
|
The patch will be accepted if there is broad consensus that it is a good thing.
|
|
Developers should expect to rework and resubmit patches if the code doesn't
|
|
match the project's coding conventions (see `doc/coding.txt`) or are
|
|
controversial.
|
|
|
|
The `master` branch is regularly built and tested, but is not guaranteed to be
|
|
completely stable. [Tags](https://github.com/bitcoin/bitcoin/tags) are created
|
|
regularly to indicate new official, stable release versions of Xcoin.
|
|
|
|
Testing
|
|
-------
|
|
|
|
Testing and code review is the bottleneck for development; we get more pull
|
|
requests than we can review and test. Please be patient and help out, and
|
|
remember this is a security-critical project where any mistake might cost people
|
|
lots of money.
|
|
|
|
### Automated Testing
|
|
|
|
Developers are strongly encouraged to write unit tests for new code, and to
|
|
submit new unit tests for old code.
|
|
|
|
Unit tests for the core code are in `src/test/`. To compile and run them:
|
|
|
|
cd src; make -f makefile.unix test
|
|
|
|
Unit tests for the GUI code are in `src/qt/test/`. To compile and run them:
|
|
|
|
qmake BITCOIN_QT_TEST=1 -o Makefile.test bitcoin-qt.pro
|
|
make -f Makefile.test
|
|
./xcoin-qt_test
|
