In an RSA blind-singing based currency, like Taler, a mint who issues the c=
urrency can track how much money a particular account sends or receives, bu=
t cannot discover the actual transfers.   And deanonymizing one transaction=
 does not impact a user's anonymity overall.  =


In Bitcoin, et al., everyone can track everything about every account at an=
y point in the past.  Accounts are pseudonymous and creation is distributed=
, but deanonymizing a single transaction destroys the anonymity of the whol=
e account.  And advanced attacks can be brought to bear on identifying sock=
 puppet accounts.  =


Yes, RSA blind-sinigng assumes the buyer remains anonymous to the seller, l=
ike say buying server time for an anonymous website.  Anytime you deanonymi=
ze yourself to a seller, like by buying physical goods, then you=92re trust=
ing them, this goes for Bitcoin too.  In fact, deanonymizing yourself like =
this is much worse in Bitcoin. =
