I think there is a pretty significant crypto flaw in Bitcoin as currently implemented. I’m not sure it is exploitable now (I’m not a real cryptohacker) but it is more than plausible that will be in the near future.

The flaw would enable anonymous stealing of coins from arbitrary bitcoin addresses. And no it doesn’t involve solving any of the hard problems that keep existing crypto systems secure. It is simply a *potential* correctable logic flaw in the implementation.

I would like bitcoins to succeed, so I’d rather not jump up and down in public yelling about flaws in public. Is there an appropriate place to discuss these types of issues?

It’s best if you tell it to me privately so it can be fixed first.

I just e-mailed you my e-mail address.  (or you could PM me here)
