Technical: First, the system should be built. The rules and simulation show that the logic is not complicated (mathematically – it can still be somewhat complicated for a user to understand). However, if the system would have thousands, millions, billions of members, who spend hours with this daily, it would need massive computing capacities (probably quantum computers in the long run) and memory storage units. It is possible that the best way to go is having competing systems (with the same basic rules and logic), but those should be interconnected (otherwise the users would be stuck in a silo). Transition: Transforming all current systems is not an easy task. CoIn could be a voluntary experiment – it would be interesting to see how the system reacts to real-life scenarios. It may work well as a supplementary system for a while. CoIn’s “currency” (that could be built on blockchain technology, just like cryptocurrencies) could slowly replace the current currencies over time. Rules related to ownership and inheritance could be implemented gradually: announcing the start of the implementation years in advance, applying the new rules only starting from the next generations, etc.
