Role of blockchain in ensuring Ad transparency

Programmatic marketing and online platforms have contributed to the growth of digital advertising. Nonetheless, the growing complexity of the advertising supply chain has raised serious questions about accountability, fraud, and transparency. This study examines how blockchain technology could enhance the digital advertising ecosystem by increasing transparency. The blockchain is a decentralized, unchangeable ledger of transactions for advertisements, allowing real-time verification of images, clicks, and money lodgments. With blockchain technology, advertising fraud, unknown charges, and information asymmetry in Internet advertising markets can be resolved, the number of intermediaries can be reduced, and data credibility can be ensured. It is presented through a qualitative approach, drawing on secondary sources, such as academic publications and reports on the application of blockchain-based solutions, to assess the practicality of providing greater transparency and trust for advertisers, publishers, and the advertising platform.
