Python Zcash miner - based on epyzcm. Currently supports mining on CPU (morpav's CPU zceq-solver) and on GPU based on silentarmy project.

In order to build a self contained binary without any dependencies build a base docker image:

The script below downloads slushpool basic image and then appends all necessary dependencies for the miner itself. The steps are described below:

• clone this repository

• cd pyzcm

• download AMD APP SDK V 2.9.1: http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/ Due to licensing reasons, it is not possible to automate this step.

• ln -s AMD-APP-SDK-linux-v2.9-1.599.381-GA-x64.tar.bz2 amd-app-sdk-installer.tar.bz2

• run the docker image building script:

docker-build-docker-image.sh

docker-build-miner-app.sh

The result of the build is in dist/ directory

Since the script also builds the zceq-solver library it maybe required to adjust its build options. See the ZCEQ_SOLVER_BUILD_OPTS variable in the script that can be adjusted. Example in the script shows how to disable profiling.

The example below runs the miner with CPU mining and 2 instances solver per GPU using all available GPU's with platform ID 0

./dist/pyzcm --cpus=0 --gpus=0: -e 2 stratum+tcp://honzik666.gpu0_0@zec.slushpool.com:4444

You can run the miner in verbose mode with -vvv option. The output should provide sufficient information for troubleshooting any issues.

apt-get install python-dev
apt-get install gcc
apt-get install libffi-dev
apt-get install virtualenv

virtualenv --python=/usr/bin/python3 .zcashvenv3
. .zcashvenv3/bin/activate

pip install numpy

Solver backend python modules - see Dockerfile and docker-build-miner-app.sh for installing backend solver modules or individual modules for documentation how to install them

cd pyzcm
pip install -e .

pip install wheel
python ./setup.py bdist_wheel

The result is a self-contained executable that has everything bundled. The upx-ucl below is optional - it enables compression of the resulting executable.

• Install prerequisities:

pip install pyinstaller
sudo apt-get install upx-ucl

• Build the executable:

pyinstaller  --log-level=DEBUG ./pyzcm.spec
