I've finished implementing the GNU mp library in perl of which I've already extended to work with an Object Relational Database. All this together gives me very fast access to numbers in the order of 8192 digets in base 36, geesh I have no clue as to how many base 10 digits that is but I feel that its proabably enough to play with some digital cash prototypes... So those that want to start formulating some REAL implementations of protocols of digital cash I'm offering to run the "virtual bank" and implement the server side protocols. I'd like to see how some of these theries realy work in practice, yes I'd encourage double spending as soon as we can get some apps up to accept whatever we decide upon for the cash protocol. I'd like to see if all the discussions about digital cash can realy work!!! would anyone else like to put their (virtual) money where their mouth (or keyboard) is ? -Rick
