In the context of trade globalization，the production and sales of economic activities are becoming increasingly complex. The emergence of supply chain finance，making the parties involved is no longer independent of the individual，but in the logistics，information flow and capital chain to become a co-ordination，close cooperation as a whole. However，enterprises in smalland mediumsize and core enterprises are all faced with pain points in the modern supply chain financial system：For small and medium enterprises，they rely on the core of large enterprises to survive，their bargaining power is low，and it is easy to face cash flow problems for them；for the core enterprises，although they are in the core of the supply chain，they face a large number of small and medium supplier or dealer，it is easy to generate bad debts due to information opacity and confusion in account management.

The root cause of the above pain point is that the flow of information，business flow，logistics and capital flow can not be integrated in the supply chain operation. The block chain technology has the five characteristics of de-centralization，timing data，collective maintenance，programmable and safe and credible，and can solve the above problems fundamentally and help to reconstruct the reliable supply chain credit system.
