One of the great advantages of safecoin is it’s anonymity. It seems very much as if it will be digital cash in a very real sense.
While a receipt for physical cash can easily be managed face-to-face with cash, putting it in an envelope and sending it requires a high degree of trust between parties. With bitcoin and the like, there is the blockchain. With other electronic currency transactions, there are counterparties such as banks and credit card companies to show proof of receipt.
I haven’t seen anything so far that deals with this aspect of safecoin transactions–i.e., verification or proof of transmission and receipt between the parties involved that can provide validation and audit, even if on a voluntary basis only, like writing a cash receipt. It seems that this is a vital aspect for safecoin to be useful as a currency beyond purchase network resources, etc.
@dirvine (or anyone else who actually knows): How is this aspect of economic action with safecoin dealt with?
