the power currently expended by computing hashes in Bitcoin mining? The most obvious application would be weather forecasting: It could use a huge amount of computation, on a continuously ongoing basis, and is valuable to every nation on earth. Whether it can be lasso'ed into a bitcoin-mining engine, I don't know.

Back when mining was done with GPU's, maybe, utilizing the newly installed base of GPGPU computing therein. https://en.wikipedia.org/wiki/General-purpose_computing_on_graphics_processi... Today all relavant mining is done with ASIC's, and all the installed base of them can do is SHA-256, so no. https://en.wikipedia.org/wiki/Bitcoin_network#Bitcoin_mining https://bitcointalk.org/index.php?board=76.0 https://bitcointalk.org/index.php?board=81.0 rysiek wrote:

My dream would be a distributed github replacement (a'la gitchain) where proof-of-work is somehow related to compilation, running tests, or somesuch.

Maybe I just saw some news about a distributed repo. Too much distributed noise lately, so maybe not. Central here, signing off...
