Most of the protocols I'm finding for digital cash don't have much in the way of dynamic range. Generally, there is a range of values that they are designed for (rarely more than a factor of a thousand or so from smallest to largest) and smaller payments become impossible and larger payments become impractical. The problem is particularly severe for offline protocols, where you can't get the bank online to make change or issue arbitrary-valued coins. Does anyone know any happy exceptions to this rule, where payments ranging from a millionth of a token up through several million tokens could all be practical? (ie, dynamic range of the twelfth or higher order?) Anyway, the "practical in arbitrary amounts" assumption is pretty fundamental to useful money. We achieve it through bank drafts, checks, transfer orders, etc. But these instruments are not as clear how to do in a digital world where anonymity is preserved. In particular, I haven't found low-level details of how the "Mojo" tokens in use by the new MojoNation stuff work. Are they just an implementation of a well-documented protocol, or did they do something new? Bear
