Making a proof of work algorithm do some actually useful work is very much an unsolved problem.

I don’t necessarily mean “useful” in the sense of scientific research or something. Simply transferring value to the creators of the resource being accessed (a la a blockchain) instead of doing throwaway work would be an improvement.
