Blockchain Offers New Hope to Combat Misleading Advertising

On November 25, 2025, new research from UvA communication scientist Dasha Antsipava highlights a potential solution to the persistent issues of online scams and misleading advertisements. Her study advocates for the use of blockchain technology to enhance transparency, traceability, and trustworthiness in digital advertising.

Antsipava’s dissertation outlines the detrimental effects of misleading advertising on consumers, brands, and society as a whole. She argues that blockchain could provide both practical and ethical safeguards against such deceptions. The research involved insights from various stakeholders, including consumers, advertisers, regulators, blockchain experts, and the news media, revealing a complex landscape of perceptions regarding misleading advertising.

Understanding Stakeholder Perspectives

Throughout five sub-studies, Antsipava investigated how these groups view misleading advertising and their responses to blockchain-based solutions. The findings indicate a growing awareness among consumers that online deception poses a serious threat. Yet, many consumers express a lack of confidence in their ability to protect themselves.

The role of media coverage is significant, as it often portrays misleading advertising as a complex issue, while simultaneously placing the onus on consumers to avoid pitfalls. This dual narrative can create confusion and distrust in the advertising landscape.

Transforming Advertising with Blockchain

Blockchain technology, widely recognized for its role in cryptocurrencies, functions as a secure digital ledger that records transactions across a distributed network. Antsipava posits that this technology could revolutionize the online advertising sector by creating a tamper-proof registry for each advertisement. This registry would detail who created the advertisement, when and where it was published, and any subsequent modifications.

In a blockchain-driven advertising network, advertisers would need to verify their digital identities. Each advertisement could be permanently linked to its source, empowering regulators and consumers to trace authenticity and hold violators accountable. Such a system could significantly diminish advertising fraud, eliminate fake endorsements, and assist consumers in making informed purchasing decisions by validating the legitimacy of brands and their claims.

Despite acknowledging the negative impact of misleading advertisements on brand reputation and consumer trust, many advertising professionals remain cautious about adopting new technologies. Antsipava’s interviews with industry experts revealed that the successful integration of blockchain into the advertising ecosystem hinges on collaboration among advertisers, publishers, regulators, and technology providers.

Currently, consumer trust in blockchain remains low, primarily due to a lack of awareness and its strong association with cryptocurrencies. However, perceptions may shift as the technology gains traction in various sectors beyond finance.

As the advertising industry grapples with the challenges posed by misleading advertisements, blockchain technology presents a promising avenue for enhancing transparency and restoring consumer confidence. Antsipava’s research underscores the need for collective action among all stakeholders to realize the potential of this innovative solution.
