The morning paper had a post about it the other day[1], but I'm not sure if the solution is acceptable to the usual cryptocurrency crowd because it depends on running the useful code on a secure enclave (like Intel's SGX) to ensure single-threading and correct count of useful instructions that were executed. The miners are then rewarded according to number of useful instructions they executed. (The correctness of the instruction count and the work done can be validated cryptographically with SGX). I thought it was an interesting concept nonetheless.
