About Repbin: Repbin is an encrypted pastebin for the command line that runs over Tor! Repbin servers form a distributed network where nodes sync posts with each other (like in Usenet or BBS/Fido systems). This makes Repbin resilient and scalable. Repbin focuses on privacy (encrypted messages) and anonymity (padding and repost chains). To limit spam and denial-of-service attacks, Repbin uses the Hashcash proof-of-work algorithm which is widely known from Bitcoin mining. Learn more about Repbin here: https://github.com/repbin/repbin/blob/master/README.md Has anybody ever considered the idea of doing otherwise-useful CPU work with 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. Jim Bell
