-- What we want of a payment system, is that Alice can prove she paid Bob, even if Bob wants to deny it, but no one else can prove that Alice paid Bob unless Alice takes special action to make it provable. (This provides permits recipient anonymity in that Bob can be an alternate identity of Dave, and no one can prove that money paid to Bob actually winds up with Dave. They can, however prove they paid Bob.) If Alice pays Bob in unblinded tokens, this does not help, for Bob can pass the unblinded tokens to yet another identity of his, Fred. One solution is for the bank to maintain an email linked account for Bob, into which Alice pays. This sounds ominous, for the next step might be to link the account to true names, can anyone see any other problems with it. --digsig James A.
