12.7.3.4 Container of the Evaluation Functions
The evaluation functions
F
trans
e
and
F
prop
e
are represented by a combination of
equations and look-up tables. We call this a function container. The mobile agent, a
part of the information capsule, uses the container to evaluate values when the
transactions are requested. Each entity has to register the evaluation functions in
advance.
12.7.3.5 Conversion of the Values into Securities
The first and second values are converted into the third value by issuing securities.
Some parts of values that an entity receives may be the third value and can be
circulated one after another. Other parts of values may be the first or second values.
