A crazy politician (named Tronald Dump) is elected as leader of a country. Being crazy, he changes to the national currency to be donuts with the following conversion:
- Doughnut Hole = 1d
- Glazed Doughnut = 5d
- Frosted Doughnut = 10d
- Longjohn = 20d
- Premium Doughnut = 100d
(The d stands for "doughnut")
The federal reserve turns into a massive bakery, churning out trillions of donuts when they want to stimulate the economy.
How would the government prevent counterfeit donuts from being produced?
