comment Prevent double-spending with decentralized digital currencies without all transactions being public?
@ripper234 no, it shouldn't. This is already the second place I asked the question (it was asked at cstheory originally) and it was decided in a meta discussion there that I should repost. Usually questions are only migrated if they are off-topic on the original site; this question seems to be ontopic here, and already generated a very good answer.

comment Prevent double-spending with decentralized digital currencies without all transactions being public?
@David this is a good answer; but it feels like two in one. In particular you give some arguments for what can't be achieved, and then you give a second answer which shows an improvement on bitcoin's scheme. I would like to accept the second answer, but I don't find the first one rigorous enough. If you could make the second part of your answer and maybe even elaborate on "I've discovered a truly marvelous solution to this problem, but this answer is already too long." as a separate answer, that would be awesome!

can you give an explanation of an implementation that does not keep track of the accounts the coins passed through? Since that would answer my question very nicely.
