What is wrong with the original solution proposed in my original
article, <http://www.jim.com/jamesd/kong/anon_transfer.htm>
The client uses an existing used coin for blinding the newly created
coin, preferably a coin that he got from someone else, not a coin
issued to him by the issuer. If the coin issuer marks coins by using
a different key for some coins and not others, the blinding will
generate unrecognizable garbage and the system will fail.
