Relying on block chain technology, it can truly and reliably record and transfer capital flow, logistics and information flow. The transportation process of goods can also be clearly recorded on the chain, and the whole process of loading, transportation and picking up goods can be clearly seen. Through the block chain, all the steps of the goods from sending to receiving are recorded, ensuring the traceability of information, thus avoiding packet loss and false claim. Enterprises can also grasp the logistics direction of products through block chains, prevent goods from being diverted, help crack down on counterfeit goods, and ensure the interests of dealers at all levels below the line.
