I was actually thinking about running this on a lot of not-so-strong computers, rather than focusing on running on a small amount of strong ones. For example, I have two old computers who are idle, I can use them for this project.
Alright, but it would help if you encrypted all the pool traffic with TLS, just so that you could run this on computers in different areas without having to worry about LAN headaches or about someone eavesdropping on the traffic and stealing he private key after your pool solves the puzzle.
Indeed. ARM is generally much more efficient than GPU, but for this task, i can't tell exactly, because i didn't benchmark it yet. remember that a GPU must be connected to a computer with a CPU to run properly. hence we need energy for the CPU and CPU memory as well.
I honk all the M1/2/3/4 chips in particular might be faster than all RTX GPUs at compute - I don't know. There's no device-to-host copy overhead at least.
