Very interesting idea, anyone know how many Apple users have a bitcoin node running? And linux one?.
I dont use Apple/mac things so i cant try. One thing it comes to my mind is, following the politics of Apple in general we have to think in the future some Apple upgrades to deny you use their computers to do this kind of things, you know...... Apple things.
That should not be so easy to find out. But the demand or interest seems to be confirmed with this project.
I think there will be quite a few Linux nodes. Just think of all the umbrel nodes that use umbrelOS. This includes all the Raspberry Pi's or any Ubuntu system.
In contrast of that: the total number of nodes that are accessible in the network can be determined.
Bitnodes.io gives a nice overview with some interesting statistics. How the nodes are distributed by country and so on.
44817 active nodes are currently available, these statistics are updated every day.
