thank you for the run down!
Say I have some Lucrative, value 1550 units.
So its like one certificate for 1550 units.
Say I want to give you say 20.50 units (say I've just bought a car from you, for example)
Do I sort of gve you the 1550 and you give me a new one, change, or can i "split up" my 1550 one into smaller, uh, sections?
I think Patrick has adopted the method used by Digicash: binary value coins (1,2,4,8,16...). Not very intuitive for most people but it allows simpler optimization for change in your purse. Keeping correct change and getting it when needed will, by default, be handled automatically for the user.
In your example 1550 units could be held in your purse as 1024 + 512 + 8 + 4 + 2. I'm not sure how he intends to handle fractional amounts but it could certainly be done using binary decimals.
