I send a message to the mixmaster I'd like to use, containing a coin and a large arbitrary number. I then put that number in a list I maintain of the tokens I can spend with that mixmaster. The mixmaster cashes the coin at once[1], and puts my number into a list of 'paid' tokens it will accept. When I want to spend the token, I put that in the message header block. Since its smaller than the coin, its easier to put in the header than the coin. This scheme also reduces mapability between the coin and the message, since they are not strongly correlated in time as they would be if they were included in the message. This seems to be a stronger win than the size benefit that caused me to suggest this. [1] Other than the time mapping win, I could also see spending a few bucks at the start of each month to be able to use any mixmaster. The mixmasters would, by cashing my coins early, win on the float between the time they get my money and the time they provide service. Icing on the cake.

Heh. See suggestion #1 in the Hack Digicash promotion. "Reverse-engineer the protocol." The protocol is unknown, I don't even know the format of the coins. I am sending in my account application tomorrow.
