Create a financial document that cannot be forged or disputed
Let’s imagine there is a village somewhere where people still trade by bartering. John has some apples whilst Lizzie has some oranges. John would like an orange, and offers Lizzie an apple in exchange. She accepts, and writes John a receipt.
