Hi...
In the Cyphernomicon, section 12.6.6, Tim May writes:
- Chaum went to great lengths to develop system which
preserve anonymity for single-spending instances, but
which break anonymity and thus reveal identity for double-
spending instances. I'm not sure what market forces
caused him to think about this as being so important, but
it creates many headaches. Besides being clumsy, it
require physical ID, it invokes a legal system to try to
collect from "double spenders," and it admits the
extremely serious breach of privacy by enabling stings.
For example, Alice pays Bob a unit of money, then quickly
Alice spends that money before Bob can...Bob is then
revealed as a "double spender," and his identity revealed
to whomver wanted it...Alice, IRS, Gestapo, etc. A very
broken idea. Acceptable mainly for small transactions.
But as far as I got Chaums idea, Alice would not reveal Bobs identity,
but rather her own. Am I missing a point here?
Andreas
