This is probably not an original idea, but... Here's a potential use for E-cash: a server that doles out Java apps to clients; the clients run the apps, calculating whatever results are needed, and uploads the results in return for E-cash (perhaps a zero-knowledge proof that the result is accurate? another is to use only a trusted pool of registered and accountable users rather than anonymous clients). The server admins would be paid by those who need computations, keeping a percentage and using the rest to be offered as E-cash to clients with spare computing power. A lot of possibilities here... a configuration where a set price is offered for a computation (the user can check for the highest offer on a server, or refuse an offer below a certain amount). Or maybe applets would only be doled out to systems that meet a certain criteria (minimum computing power). A more complex system where 'bids' are placed based on computing power is possible too (those w/better systems would want more cash, or be willing to pay it). Problem: open to forms of 'abuse' (imagine a sysadmin making E-cash using his employer's machines overnight). It might make an interesting experimental project to work on. --Rob ----- "The word to kill ain't dirty | Robert Rothenburg (WlkngOwl@unix.asb.com) I used it in the last line | http://www.asb.com/usr/wlkngowl/ but use a short word for lovin' | Se habla PGP: Reply with the subject and dad you wind up doin' time." | 'send pgp-key' for my public key.
