When dealing with two different assets say a bond, money for a DVP when mapped to a real world they impact a custody/demat account and bank/cash account. Any thoughts on how the distributed ledger can relay changes to the physical world? I have heard the concept of selling to one-self. How does that work? e.g. use the money from the bond sale for some other purpose, sell the bond to an entity outside the private blockchain pool, etc.
