I like this concept, Hive account@rebelnutrtion:-), it is yet another example of where the blockchain can greatly reduce complexity and inefficiencies while adding transparency and validation to the process! One question I have is how it would work to overlay an options system, even to the extent of hedging for price stability of the big buyers. I have traded options in the commodity sector on and off for a few years, and I have not seen a good system yet for replicating the market-making side via DLS. You are spot on about the profit potential for the CME replacement! Very thought-provoking post:-)
