That’s a quite innovative idea!
The way this can be done is rougly as follows:
- QubesOS would have a public XMR donation address (something like, 4afjLKJA18941…)
- Users would install xmrig on one of their AppVMs (they can build from source)
- Users would install pinodeXMR software solution for running a Monero-node in one of single board computers at home (like raspberry pi)
- Users, within QubesOS XMRig AppVM, would point their xmrig miners to their monero-node p2pool, and provide the miner payout address as the QubesOS project monero donation address!
