Re: What backs up digital money?

I will put forth the proposition that Federal Reserve "Notes" are not notes. A note is a promise to (a) pay (b) a certain amount (c) at a certain time (d) to a certain person. As in the phrase that *used to* appear on United States Currency: "will pay the Bearer One Dollar in Silver upon Demand". The only extant legal definition of a dollar is a Federal statute of 1792, defining it as a certain weight of pure silver.
