I love theoretical computer science, but since college I've mostly worked "in industry" and been pretty distant from anything resembling serious math. That recently changed, though, when I started working through a textbook on computational complexity, problem by problem [1]. http://andrewbadr.com/log/13/identity-memory-and-making/http://andrewbadr.com/log/12/one-angle-on-art/ Of the music I listened to ten years ago, only one album is still in rotation. The rest of it fell away as, piece by piece, it started to seem shallow. In high school, I probably thought my parents didn't understand my music, since it wasn't from their era. Instead, it's possible they understood it better than I did. http://andrewbadr.com/log/12/one-angle-on-art/http://andrewbadr.com/log/11/anonymizing-bitcoin/ Bitcoins are not anonymous, but they can be made more so. All existing "laundries" are ineffective. These are my thoughts on why, and how an ideal anonymity-strengthening relay (ASR) might work. I'd been waiting to post this until I reached more definitive conclusions, but Kaminsky's announcement of BlitCoin made me think it was better to get a discussion started earlier. A more secure Bitcoin is a more useful Bitcoin. There are just a couple ideas here, mostly obvious, taken to their logical conclusion. http://andrewbadr.com/log/11/anonymizing-bitcoin/http://andrewbadr.com/log/10/bitcoins-and-why-im-buying-them/ Bitcoin is the name of a new digital currency. You have a file on your computer that says how much money you have, and you can send amounts of your money to other people using the Bitcoin client. Bitcoin has no central authority, but thanks to some advanced math, the files saying how much money you have can't be forged, nor can the transfers be faked or revoked.
