Not 1 clue. What is this?
Rai. OG analog money.
These are Rai stones from the Yapese Islanders. They used these as currency up until white folk travelled to the island and created more with modern tools (similar to modern day inflation and printing machines). These were a scarce form of currency and lays the history for how scarce money worked well as long as it is not inflated. These are covered in Chapter 2 of the Bitcoin Standard.
