Digital technologies such as digital platform, big data, artificial intelligence and blockchain may create a brand-new wealth management platform. The problem of product homogeneity in China's wealth management market is, in the final analysis, the structural defects and technical shortcomings of resource allocation, and the digital platform fills the shortcomings of resource allocation. For example, the interactive link architecture based on blockchain can create a financial transaction platform that links many financial institutions, many products and many customers, and realize point-to-point and end-to-end links and transaction combinations. Today is the information age, and more and more researchers pay attention to the digitalization of information. As early as 1940s, Shannon proved the sampling theorem, that is, under certain conditions, a continuous function can be completely represented by a discrete sequence. In essence, sampling theorem lays an important foundation for digital technology.
