Abstract: A blockchain-based member tracking system, communicatively connected to multiple web servers and multiple user devices, comprises an advertising database, multiple advertising modules, a primary member database, and a blockchain module. The advertising modules are configured to run on the web servers and are configured for displaying the advertising data. When the user device connects to the web server, the blockchain module generates a set of the preference tags and a set of the point data, and associates them with the corresponding member data of the user device. When the user device connects to the web server, the advertising module selects the advertising data based on the corresponding member data and the preference tags. The preference tags are a form of non-fungible token data.
