This'll happen, probably sooner than later.
Hm, how about using two public-key algorithms simultaneously (ie, providing signatures made using two algorithms with each coins)? This way, if one algorithm gets broken, there would be supposedly enough time to make a transition to another method or at least honor the issued ecash. Just curious. Another question: what happens to the ecash issued by a bank if it's secret keys get stolen? Thanks, - Igor.
