I don't see there being any formal need for an expiration data. the
toolkit should accept a specification from the caller stating which
stamp versions are acceptable. For example, after we decide that
version 1 stance are sufficiently stable and are the one true way,
systems using Hash cash should be able to devalue version 0 stamps
within the stamp generating/validating subsystem.
the default case should be to accept all stamp versions known and to
generate only the highest version.
I would however hold off on the transition to testing. I'm trying to
find the time to put in file locking on the double spending database and
I hope to have it working in the next day or two.
