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?
a zombie in this context is a brain the (CPU) eating process that
generates stamps. A bad zombie generates stamps for a third-party
without the consent of the owner of that machine. A good zombie
generates stamps for a third party with the consent of the owner of that
machine.
overall, it's very much like your example of the SETI approach to
distributed computing.
the big difference between good and bad zombies besides the permission
of the owner is that the good zombies have an authentication system
which allows the owner to control who requests stamps from them.
for example, on the first request from a site, there could be some sort
of certificate or identity exchange like the one that Simon has been
talking about. Once the identity has been received, the user could be
informed with the options of: burn one stamp, always burn stamps for
this identity, no way, you can't have any of my CPU. And little zombie
can have its way with your CPU at whatever efficiency rating you have
told to use (bwahahaha, okay I'll be nice just this once, Rick Van Winkle).
So the owner is always in control can always get the information they
need in order to make an informed decision to do the right thing for
themselves.
