According to TheAsianBanker, Xie Yonglin, chairman of Ping An Bank, said in an interview that the blockchain and the Internet of Things will reshape the service model of the entire commercial bank in SMEs. Everyone knows that many companies are connected by trade finance, and our biggest trouble is that trade finance must have a real trade background. In the supply chain, the circulation of goods is fundamental to trade finance. Then the Internet of Things and the blockchain will make the authenticity of trade financing fully present, and the cost of manual operations will drop sharply. The problem of financing and financing for SMEs will be improved under the application of new technologies.
