I have a few questions to ask about setting up a mining pool
1) Will there be an issue if I set up two geth instances with the same coin base? Here it is not about private nodes, I am trying to do a fail over for geth, have at least two nodes running at the same time. I want to give them the same coin base, so I am a bit worried it will have some issue. like conflicts.
2)Do I need to connect as peers for the two geth instances? Do I need to manually connect these two instances as peers?
3)Is it same if I keep mining with 2 geth instances or just one? If I have two regional services, e.g. one at US, and one at Russia. Is it same if I have own regional geth instances to mine separately, or I have to point one regional pool to another region geth instance to force them mining on the same geth instance.
