Someone posted a way to resist altered bank notes if the consumer's random blinding factor signed by the bank wasn't really so random, by something called (if I remember right) a "cut-and-choose" protocol. To make things very simple for a bank, I suggest having fixed value digital pseudonyms for each value of bank note. For example, the Bank of Hastings on Kent would use "AU 500 mg from HoK Bank" as the user name for all signed 500 milligram gold certificates. When a merchant or ultimately the bank verifies the note, it will see "AU 500 mg" as the message, or will not accept it. No worry about spoofing. Kent - <jkhastings@aol.com>
