[1] do we have anyone in the audience who works for an ISP or a hosting

where people become users of stamps and participate in the good zombie

interface for authentication of requesters for stamps.


There's one small piece I've been confused about for a while now, and that's
the definition of 'zombie' in this context. My understanding is that a
zombie is an internet-connected PC which is infected with a trojan which
allows a malicious 3rd party to access its resources. In the case of
Hashcash the 3rd party would be a spammer who wants to use the zombie PC to
generate stamps. Am I correct so far?

Or is the zombie PC used solely to send spam, without calculating the
stamps? Or both?

So in the case of a 'good zombie culture' the PCs are running a legitimate
background process which generates stamps both for the user and others in
their trusted group. Almost like the SETI approach to distributed computing.
Do I have that right?
