If you haven't already, please read Planet Nine's First Experiment, as it sets the stage for this one.
In modern transactions there are three participants: buyer, seller, and facilitator. Buyer pays the seller, and the facilitator takes a piece for the trouble of maintaining the marketplace.
But if we're on computers where we can just make stuff up anyways, why not do something fun for the buyers and sellers? What if every transaction created a nineum or two for them?
Our first experiment gives us an expendable currency to use around our marketplace, what would happen if its use created these taxonomical tokens?
Then what if people within the marketplace used these tokens in different contexts, and in so-doing granted to them value?
Like with the currency, I have a lot of ideas of what could happen, but I'll leave this open-ended, but with one exception: The Tale of Two Tokens.
