Let's build one.
If I'm not mistaken, this is the roadmap to get from where we are now to having a zcash mining pool (which will greatly reduce the variance of the reward for miners, and therefore encourage more mining by more people).
(1) Build a stand-alone miner. I'm thinking we can fork and modify cpuminer, (perhaps grabbing code from zcash's miner.cpp?).
(2) Set up a pool on a dedicated AWS EC2 server.
(3) Everyone profits.
I'm not familiar enough with the guts of cpuminer to be able to do (1) readily. If anyone else is and wants to volunteer please let me know. If no one steps up then I'll just try to find the time figure it out myself.
Number (2) is pretty straightforward after we have (1).
Is anyone else interested in this? Or are most folks planning to solo mine?
