The document summarizes a research project on optimizing digital advertisement systems. It discusses researching target users' behaviors and concerns with digital ads, such as privacy and irrelevant ads. A proposed solution is a blockchain-based platform that allows users to personalize ad preferences and have transparent control over personal data usage. The platform would use a chatbot interface and reward users with tokens for interactions like providing purchase data to advertisers. The research tested usability of the concept and set key performance indicators to measure outcomes like ad relevance and user satisfaction.
