Steve,

You made a good observation. However, it does not nullify the assertion that if
the appropriate
parameters of trusting the source, and genuineness of the dollar can be 
verified,
then we shouldn't
have a problem.  So if theft of the dollar is a concern, then add a verifiable
"stollen/not stollen" paramater.

Regards,
Alex.

Ed,

You made some interesting points which leads me to wonder if
we can define Trust in such a way that its parameters are verifiable,
then we can verify that it is transitive. In other words, if Jon gets
a dollar from Mike, and Jon can verify the parameters of the dollar,
then Jon doesn't care about the "trustworthyness" of  Mike's source.
Or should he?

Regards,
Alex.

I didn't want to comment on this example, but your message forces me to do so.

Jon verifies the dollar, which is a bearer credential, and not Mike,
the person from whom he received the dollar. (The dollar could have
been stolen by Mike!) This example says nothing about transitivity of
trust.
