Stone money: Ancient antecedents to bitcoin

Recommended Posts

Still Waters

Bitcoin and the blockchain may seem like puzzling new technological concepts, but the central tenet of this cutting-edge cryptocurrency goes back way longer than you might believe.

Strange as it may seem, bitcoin has a kind of bizarro historical analogue in an ancient currency system dating back hundreds of years: giant stone disks called rai, which were used long ago as a symbolic form of money on the Micronesian island of Yap.

"Carved from limestone quarries located in the Palau islands some 250 miles (400 km) from Yap, they're the largest objects ever moved over the open Pacific Ocean during the pre-European contact era."

I always wondered if they were more than that. Perhaps sacred.

I also wondered if they had the same origin as Bi. Which are jade discs with a central hole which are kept as good luck charms and given as gifts all over Asia. 

https://en.wikipedia.org/wiki/Bi_(jade) This article doesn't explain it in full. Many small "lucky" Bi are still undecorated.

@third_eye  Whatcha think Sofu?
