The ideal system from an anarchist point of view is a double-blind system (both paries in an exchange are anonymous) but there are systems out, most of them designed by the foremost financial cryptographer David Chaum where only the buyer is anonymous but the merchant is not.Systems also differ by wether they have an offline capability, the issue being to forbid people spending the same digital coins at different merchants. This is relatively easy to avoid in an online, transactional system and very hard to avoid in a system with offline capability.
