LG to Launch Blockchain Platform for the Digital Advertising Market

Through its Blockchain Research Lab division, the South Korean company is building a Web3 solution for the advertising industry on Arbitrum, a Layer 2 blockchain network. The platform is designed to provide advertisers and publishers with a shared marketplace of available advertising inventory while tracking how users interact with ads.

LG identified three key challenges facing the industry:

• Fraud remains a major concern, as automated media buying allows fraudulent impressions to masquerade as genuine activity.
• Data restrictions continue to tighten, making it increasingly difficult for advertisers to collect and use user information.
• Engagement is also declining. Advertising traffic continues to grow, while audience response rates are falling.

The system is designed to record ad delivery as verifiable proof, documenting who served an advertisement, when it was delivered, and in what format. LG said data processing will be privacy-conscious, while the settlement mechanism is intended to reduce losses associated with invalid traffic.

The project also seeks to shorten the chain of intermediaries between buyers and sellers of advertising inventory. In traditional programmatic advertising, multiple intermediaries facilitate transactions and manage placements, significantly increasing costs. LG believes a blockchain-based platform could streamline this process.

The company has already completed a pilot test of the platform with Japanese advertising agency Hakuhodo. The trial was conducted under real-world conditions and involved users in Japan. LG evaluated several factors, including how naturally users perceived the advertising format, how the operating model performed, and how accurately campaign results were analyzed. The results are currently under review.

Samuel Park, Head of Blockchain Research Department at LG, said the company is assessing whether the approach can deliver meaningful benefits to advertisers, publishers, and audiences. Arbitrum co-founder Steven Goldfeder said the model could effectively automate the programmatic advertising market and reduce the need for manual intervention.

The initiative reflects a broader trend of large corporations developing proprietary blockchain solutions for specific business needs. LG is focusing on the advertising sector, where even modest reductions in costs and improvements in transparency could generate significant economic benefits.
