Rather than having my mining rewards go to a new/different coinbase address for each block I find, I'd like to be able to specify a single/particular/fixed coinbase address that will not change with each block discovered.
The motivation is to improve key-management and decrease the likelihood of losing mined coins. Here's where I am:
I'm currently doing some experimentation that works like this:
- I set up a particular software configuration specific for mining.
- I take an image of the the machine.
- I use that same image on a handful of different machines (each with a different hardware configuration).
- I note performance differences.
My concern: because zcashd doesn't implement HD wallets, each of my instances is going to (eventually) end up with a different keypool. Which means the private keys to any newly mined coins are not in one centralized location.
My solution: set a static coinbase address in the original image. That way all my instances will be mining to the same address, and that address will never change. Additionally, I could keep that one static coinbase private key safe (offline), so that even if someone gains access to one of my mining machines, they can't swipe my coins -- because the privKeys aren't even on the machine.
The challenge, for me, is that I don't know the zcashd codebase well enough to know how to set a fixed/static coinbase address.
Can anyone help?
I appreciate it.
