In personal humble opinions, ideal, first of all, each person each device has a digital identity, so can ensure that the data of a certain authenticity, at least in the process of the said everyone is confirmed,
Each number and then analyze the data, it is concluded that the identity of the credit, traceability, incentives, such as credit, this need to run to the industry logic is especially ripe, not the layman can I know, and each figure, that need to integrate resources ability, how to breakthrough point is the most difficult,
Basic is now on the inside of the original system data or logic chain, so using block chain characteristics, establish some trust between partners,
