Digitally signed notes are not forgeable.
Right.
I doubt very seriously that there is anything on the planet that is *ABSOLUTELY* unforgable. It all comes down to how much energy and resources one is willing to sink into the project.
This is, with due respect quibbling. "Unforgeable" and "unbreakable" are commonly used terms of art, which we (mostly) all know have caveats about computational power attached to them. Purists may want all such statements modified with things like "effectively unforgeable" and "effectively unbreakable." Whatever. It's always important for people to understand that cyphers may be only computationally secure (to some amount of crunch), but one need not dwell on it. Perry was answering a "yeah, but what if people forge digital cash?" type of question. His brevity was understandable. --Tim May -- .......................................................................... Timothy C.
