Hal says: http://www.finney.org/~hal/chcash1.html and http://www.finney.org/~hal/chcash2.html Wow look at the dates on those files -- Oct 93, and we still no deployed ecash. You'd think there would be a market there for porn sites alone with merchant repudiation rates, and lack of privacy in other payment systems. www.digicash.com has some blurbs about "solutions", a few "demos" -- actually shockwave animations I can't view under linux -- and a few press releases about deals -- but no indication of where would could go to download a client or obtain a real account. Another interesting and related use for ecash would be file distribution systems which use economics to resist DoS, and give people an incentive to run them, and profits to fuel the scaling of the system to scale. Examples are Mojonation's mojo and some of my and Ryan Lackey's earlier musings about eternity / cypherspace / distributed content sharing. So in the mean time we have privacy less things like paypal apparently getting reasonable adoption. I was going to read about visa cash -- but more fscking shockwave -- the frontpage is shockwave no less so you get zip information out of them. http://www.visacash.com/ Adam
