Ecash itself is less prone to abuse than paper bank notes, because privacy is "one-way," which means that an extortionist, a seller on a black-market, or the acceptor of a bribe is forever vulnerable to being irrefutably incriminated by the party that paid them.
Now, I'm not sure of this, but as far as I can see, if I was a blackmailer wanting to receive an untraceable payment I could do the following : I create my ecash serial number/hash I blind it with a random number I send it to the payer Payer blinds it again and sends it to the bank Bank signs it and returns it Payer removes their blinding and returns the result to me I remove my blinding and send it to the bank for payment with no chance of being traced. Will this work ? Mark
