In the light of latest events, have been sitting and pondering how the future of digital currency will look like. I'm not an oracle, or anything alike, but it seemed weird that people are ready to accumulate a gigabytes of blockchain garbage AND waste a tons of computer power on solving problems that add no value to the real world. Possibly, if Satoshi Nakamoto (the pseudonymous person or group of people who designed the original bitcoin protocol) took a one step further, bitcoin would be much more widespread today AND backed up by something more substantial than human beliefs - human knowledge. There are quite a lot of institutions that use super computers to solve non-trivial problems. You probably heard about SETI@home, which uses P2P network to search for Extraterrestrial Intelligence. NASA needs a lot of computer power to track the garbage around Earth orbit, and asteroids. There are many more, including mathematicians in various institutions. These people would be happy to get access to Bitcoin mining network, and they have money to pay. I guess you get the idea, instead accumulating blockchains, we could accumulate useful information (which also has a limit). The mining pools could process real world problems and get paid for their work. Such a network is much harder to shutdown, once lifted from the ground. Because shutting it down will be equal to burning down the Ancient Library of Alexandria. Thoughts? Criticism? Shall I start to implement the protocol?
