What is LG's new blockchain advertising project?

LG Electronics is developing a blockchain-based advertising platform built on its own Arbitrum layer-2 network. The system is designed to record advertising inventory and audience engagement data on a shared ledger.

Why is LG using blockchain technology for advertising?

LG believes blockchain can improve transparency and reduce the manual reconciliation processes that still exist in digital advertising. A shared ledger could help advertisers and publishers verify campaign performance more efficiently.

How does LG's advertising blockchain work?

The platform creates a common database where advertising inventory and audience interactions are recorded. This allows multiple parties to access the same information, potentially reducing disputes and administrative costs.

What problem is LG trying to solve in the advertising industry?

Digital advertising often relies on fragmented systems and manual verification processes between advertisers, agencies and publishers. LG's blockchain network aims to streamline these workflows by providing a single source of verified data.

How large is the digital advertising market LG is targeting?

According to Dentsu, global digital advertising spending is expected to reach $740 billion in 2026. Digital advertising is forecast to account for approximately 73% of a global media market worth more than $1 trillion.

Has LG already tested the platform?

Yes. LG conducted a pilot programme with a Japanese advertising agency to evaluate the technology. The company is currently reviewing the results before deciding on a broader commercial rollout.

LG eyes blockchain overhaul of digital advertising

LG Electronics is building a blockchain-based advertising platform on its own Arbitrum layer-2 network as the technology giant seeks to modernise how digital advertising inventory is bought, sold and measured.

The project was developed by LG's blockchain research division and has already been tested through a pilot programme with an unnamed Japanese advertising agency, with a broader commercial launch now under consideration.

The platform creates a shared ledger that records advertising inventory and tracks audience interactions, potentially reducing the manual reconciliation processes that still underpin much of the digital advertising industry.

The opportunity is significant, with Dentsu forecasting global digital advertising spending will reach $740 billion in 2026 and account for approximately 73% of a media market expected to surpass $1 trillion.

Samuel Byungsun Park, who leads LG Electronics' blockchain research department, said the company is assessing whether the technology delivers meaningful benefits for advertisers, publishers and audiences before committing to a full-scale rollout.

The initiative represents LG's latest blockchain venture following previous projects including its Wallypto digital asset wallet and an NFT trading television patent tied to its consumer electronics business.

LG joins a growing list of companies building dedicated blockchain infrastructure, alongside projects from Stripe, Robinhood and Circle, while Arbitrum co-founder Steven Goldfeder said blockchain technology could help automate advertising transactions and reduce operational friction across the industry.

At the time of reporting, Arbitrum price was $0.08326.
