Something like BOINC but for hosting

cross-posted from: https://lemmy.ml/post/5768010

You know BOINC, the thing where you can donate your processing power to specific computational projects?
Is there anything like that, but for hosting platforms / services?
Something where you could say "I am willing to dedicate this much of my CPU, RAM and storage space to this project or this group of people".
Say that I have a server that is more or less collecting dust, and I want to make it do something productive.
I am aware of YUNOHost and alternatives, but that still requires me to choose which things to deploy and also somehow then offer that to the community.
As a certified lazy dude, I would much rather say "here's the computer, use it for whatever you need the most".
The issue I see with this is that my goodwill could be abused for hosting something inappropriate or even illegal, and then I would be held responsible. So there should be some transparency requirement or some other mechanism that helps prevents this.

And yes, self-hosting would not be the accurate term to describe this kind of distributed resource sharing. "croud-sourced self-hosting"? "crowd-hosting" sounds like a good description for this phenomenon.
Some implementation of this probably already exists. Please provide any relevant names or links that would help me find more about this.
