However much we'd like it to be, hashcash by itself does not make an
anti-spam scheme. Initially at least, the best places for it to work
are as a false-positive mitigator (in conjunction with a content
filter or DNSBL) and/or an introducer (in conjunction with a
whitelist). I have in development a scheme which explicitly combines
both of these approaches, and Eric has something broadly similar in
CAMRAM.
half agreement. If you look at the camram site and go to the zombie
logic/zombie calculator section, he quickly learn one thing (at lease
it reinforced what I figured was true). By playing with stamp size
and stamp usage patterns, Hashcash (or something like it) will
actually reduce the amount of spam on the net.
Well, one hopes that will be an emergent effect. Certainly because
content filters 'leak' on a statistical basis, the spammers' adaptation
behaviour has been to increase volume, so we will know whether a
deployment of hashcash has been particularly successful if the spammers
adapt to *that* - and end up reducing their own volume.
Jonathan, if your scheme is any good, I will have no qualms about
lifting it and giving proper attribution. We really need to focus on
making this technology easily available to others and I believe the
shortest path that is a devil Linux based CD-ROM.
Acknowledged. Right now my priority is to keep my finances vaguely
above the waterline, however, so hashcash is second or third on the
project list.
