>it would be cool if Bitcoin didn't require throwaway computation Sure, but that's a technology that does not exist. If you can figure out how to create a blockchain-like concept, where the 'proof of work' actually contributes to humanity, you have invented the next big thing. Edit: Reading the comments below me, it looks like this is a space that is being actively explored. Exciting!

>Curecoin puts ASICs to work at what they are good at–securing a blockchain, while it puts GPUs and CPUs to work with work items that can only be done on them–protein folding.
Do you (or anyone) have more information in how this works? Does this reward you directly for doing the folding (as opposed to validating)? How does that work? That looks like a very interesting concept, and if it's technologically sound then I'd love to see it gain popularity.
