Abstract

The embodiment of the invention discloses a data processing method and device based on a block chain network. The data processing method comprises the steps: obtaining a purchase request for purchasing a specified object, wherein the purchase request carries the user information of a target user; querying whether historical invoice information of the specified article corresponding to the user information exists in a block chain corresponding to the block chain network; if the query result is yes, determining a historical purchase quantity of the specified article purchased by the target userwithin a preset time range according to the historical invoice information; and according to the user information and the historical purchase quantity, determining the purchase quantity and the consumption tax of the specified article currently purchased by the target user. By means of the embodiment, automatic and intelligent control over purchasing of the specified articles is achieved, and effective control over the number of the specified articles purchased by the user is facilitated.
