Description Lance Haverkamp 2007-09-18 15:41:01 UTC
There is now a Thunderbird extension for stamping email (yea!).  It's called
PennyPost http://pennypost.sourceforge.net/  It can use either hashcash (which
we already support) or a newer stamp pricing system called memory bound or
mbound.   To quote Wikipedia: "Memory bound refers to a situation in which the
time to complete a given computational problem is decided primarily by the
amount of available memory to hold data. In other words, the limiting factor of
solving a given problem is the memory access speed. The application of memory
bound functions could prove to be valuable in preventing spam..."

Might we support memory bound in addition to hashcash?
