P2Pool - Harambecoin

Straighforward fork of p2pool with harambecoin network info added. Instructions are also provided in this readme for using p2pool specifically for harambecoin.

NOTE Right now the subsidy function uses a quick and dirty hack to just set the value equal to the initial reward. This should work, however, after block 29200 the first subsidy change occurs and all p2pool nodes will need to be updated with the actual subsidy function (which will hopefully be availible by then).

Requirements:

Generic:

• Bitcoin >=0.11.1
• Python >=2.6
• Twisted >=10.0.0
• python-argparse (for Python =2.6)

Linux:

• sudo apt-get install python-zope.interface python-twisted python-twisted-web
• sudo apt-get install python-argparse # if on Python 2.6

Windows:

• Install Python 2.7: http://www.python.org/getit/
• Install Twisted: http://twistedmatrix.com/trac/wiki/Downloads
• Install Zope.Interface: http://pypi.python.org/pypi/zope.interface/3.8.0
• Install python win32 api: http://sourceforge.net/projects/pywin32/files/pywin32/Build%20218/
• Install python win32 api wmi wrapper: https://pypi.python.org/pypi/WMI/#downloads
• Unzip the files into C:\Python27\Lib\site-packages

In order to run P2Pool with the Harambecoin network, you would need to build and install the ltc_scrypt module that includes the scrypt proof of work code that Harambecoin uses for hashes.

Linux:

cd litecoin_scrypt
sudo python setup.py install

Windows (mingw):

• Install MinGW: http://www.mingw.org/wiki/Getting_Started
• Install Python 2.7: http://www.python.org/getit/

In bash type this:

cd litecoin_scrypt
C:\Python27\python.exe setup.py build --compile=mingw32 install

Windows (Microsoft Visual C++)

• Open visual studio console

In bash type this:

SET VS90COMNTOOLS=%VS110COMNTOOLS%	           # For visual c++ 2012
SET VS90COMNTOOLS=%VS100COMNTOOLS%             # For visual c++ 2010
cd litecoin_scrypt
C:\Python27\python.exe setup.py build --compile=mingw32 install

If you run into an error with unrecognized command line option '-mno-cygwin', see this: http://stackoverflow.com/questions/6034390/compiling-with-cython-and-mingw-produces-gcc-error-unrecognized-command-line-o

Running P2Pool:

To use P2Pool, you must be running your own local harambecoind with server=1 enabled in your .conf file or with the -server flag. Also make sure that you have all dependencies installed including compiling the ltc_scrypt module (see requirements section). Launch p2pool with the following

python run_p2pool.py --net harambecoin -a <HARAMBECOINADDRESS>

Run your miner program, connecting to 127.0.0.1 on port 53000 with any username and password.

For additional options or to try and troubleshoot any errors you may be encounter, run:

python run_p2pool.py --help

You can view statistics from your node by opening 127.0.0.1:53000 in a web browser.
