RTC. Resistant to Counterfeiting
... how can one ensure the money (MNY) cannot be falsely created or duplicated?
If money is easily reproducible with no work or controls it will become worthless.
Money must be 'scarce'. The scarceness of it, coupled with people's trust in its value is what gives it value.
There must be a way to keep money from being 'created' in a nefarious and unofficial way.
Money must be resistant to Counterfeiting.
Counterfeiting can be battled with the Public Ledger (PLG).
