For the file storage people, there's a bunch of startups (like Storj and SIA) that have an S3-like API but slice up the files and store the (encrypted) chunks on the disks of "miners" who get paid each month for disk space and bandwidth used. Because most were started during the ICO boom they all use a blockchain token, even though there are usually centralized servers keeping track of which client uploaded which file. The clients could pay normal currency to those servers, who could distribute it amongst the miners.

I used to have a spare PC with a 13TB HDD mining Storj for a couple of years and it worked fine, but converting the tokens to currency I could use was a major hassle.
