Yes, since it can be implemented in Emacs Lisp. The idea of "proving some work has been done" is what's important. Plus it's not a well-known algorithm so there's a low chance of random spammers implementing it. c> I don't know the details of the hashcash implementation, but a quick c> internet search suggest that emacs would need to successfully c> communicate with a subprocess to a binary that isn't likely to be c> installed. That's how hashcash.el (now removed from Gnus) operated IIRC. But there's no reason we need to do it that way. See http://www.gnosis.cx/download/gnosis/util/hashcash.py for an example implementation.
