When the data economy develops to a certain extent, people will participate in it extensively and deeply, and everyone will inevitably participate in different data storage activities. In addition, with the advent of the Web3 era, most scientific and technological fields will slowly begin to upgrade or transform in recent years. As an important infrastructure of Web3, decentralized storage will be applied to more application scenarios in the future. For example, we are familiar with the data storage network behind social data, short videos, live streaming, intelligent cars and so on, and will also adopt the decentralized storage mode in the future.
