Is there any cryptocurrency that already does useful work in its mining? That seems like a great idea. You could incentivise people to do things like protein folding as long as you could also make sure the work isn't fakeable somehow (which I suspect is the big problem here).

- dgacmu 9y agoThere are three that try to find primes - Primecoin, Riecoin, and Nexus. This isn't "useful" but it's a bit more intellectually interesting than finding partial collisions in sha-2. (I wrote the miner that's now used for Riecoin.) There have been attempts to do others but none that really work, because in part of the problem you cite. It's also very hard to have a tune-able difficulty for the mining process.
