I'm not sure if any of you are familiar with this: https://classic.ripplepay.com/
It is basically a protocol that categorises debt to be used as a monetary system.
At the moment it seems that in this game, trade is managed by assigning 'points' as a measure of value. However, just like any bartering, it means that the traded valued must equal exact value, which may be difficult for goods that have different values to different peoples.
As villages trade with each other more often, would it be possible that they allow each other to be in debt to each other by a certain amount of ''points' and as the network of trade expands, this could create the ripple effect described in the site.
I am wondering if this would, essentially, become the next evolution trade in this game?
