Serious question: if the processing problems are classified as NP, then couldn't that processing be outsourced to a blockchain? Why have miners solve for useless problems that have no long lasting impact like "number of zeros in a SHA string" instead of processing data such as this? I can easily see it being the case that the mining problem in a given blockchain could be based on real scientific problems that needs solving.
I'm looking for someone to help me understand why the above isn't possible.
