dstm’s ZCash Cuda miner
#################################################


I’ve written it initially for my own purpose. It performs pretty well - so here it is.
Compatible with devices having Compute Capability 5.0 and greater i.e. it should run fine on Maxwell/Pascal GPUs.
Supports every server using the stratum protocol. If you have issues with certain pools pls. report them here.


Contains 2% devfee.


Suggestions are welcome.
