That's not going to work for web hosting. The only reason it works for crypto or folding is because each request takes minutes to run and there's no time dependence on returning the result. Additionally, they don't need much data and all data needed is dispersed with the task.
Websites are completely different. Each individual request is tiny, taking milliseconds to process. Each request is very time dependant, you have a person literally waiting for the result. But the biggest issue is that what people really want is stuff from a database. So that database would need up grant full access to everyone, meaning anyone could change whatever they wanted. Lastly, that database would need to be hosted anyway so you've gained nothing.
Don't suggest tech solutions when you don't have any idea what the problem or solution actually involves.
