For any cryptocurrency experts out there, is there any way the Bitcoin protocol could be altered (or temporarily halted while being updated) without compromising the blockchain so that instead of guessing for some hash/key combination, it could be part of some distributed computing project? Like assisting in the Folding@Home or some other project that benefits humanity in some way? I know hindsight is 20/20, but it represents an immense wasted opportunity and supposedly consumes more electricity than all of Argentina.
