So, continuing with my sudden inspiration about a cryptocurrency that
can be used locally as a non-counterfeitable dollar:
You would have an app on your phone which "contains" digital cash.
You would only use this app locally, communicating with another app on
another person's phone using Bluetooth.
If you want to add money to your app, you would have to find an ATM
machine that dispenses this cash to an app. This would be the same as
dispensing actual dollars. That means that, unlike bitcoin, the Fed
determines how much money is in circulation in these apps. There may
even be a way to simulate paper money serial numbers.
So if I have this app on my phone, and you have this app on your
phone, then we can hook up via Bluetooth and I can tell my app to send
$9.58 to your app to pay for a bag of carrots that I'm buying from
you.
If you lose your phone, you would lose your money -- same as real
cash.
Anyone can write an app. So before my app could send cash to your
app, the two apps would do some handshaking that would include a bunch
of cryptographic tests that allow each app to verify that the other
app is valid.
An additional problem is that someone could simply copy the entire
storage area from one mobile phone to another, thereby doubling his
money supply. Solving this would require some kind of writable
hardware chip that goes in the phone and goes with the app. This is
perhaps the most difficult technical problem to solve, requiring
advanced chip technology.
I think that this app-chip is technically feasible, and it would solve
a lot of problems.
