LG Electronics has begun piloting an on-chain advertising network built on the Arbitrum blockchain, aiming to create a tamper-resistant and verifiable system for recording ad impression data. The pilot project, developed by LG’s Blockchain Research Lab, is being carried out in partnership with Japanese advertising giant Hakuhodo.
Focus on key challenges in digital advertising
According to LG, the initiative addresses three persistent problems in the digital advertising market: fraudulent traffic, tightening privacy rules, and declining user engagement. The results of the live pilot test are still under evaluation.
Hakuhodo is one of the leading advertising and marketing groups in Japan. The pilot in Japan is being used to observe how the system functions with real users and whether it delivers a seamless experience when engaging with ads.
Samuel Byungsun Park, head of the Blockchain Research Department at LG Electronics, explained that they are assessing whether blockchain can enhance transparency in advertising processes and enable a model with greater sensitivity to consumer data.
LG emphasizes that key digital advertising metrics, such as impressions, clicks, and conversions, are typically maintained within closed systems. Furthermore, payment and reconciliation processes can take several weeks, making it challenging for advertisers and publishers to access a shared, evidence-based dataset.
Industry researcher WARC forecasts that global advertising spend will reach $1.3 trillion by 2026. At such scale, discrepancies between reported and verifiable performance could have a significant impact on how ad budgets are allocated globally.
Why the project was built on Arbitrum
LG’s Blockchain Research Lab designed a system that can record who delivered each ad, when, and by what method, providing an auditable trail. The company points out that in high-frequency automated trading environments, bot traffic often gets mixed with genuine engagement. By using on-chain records, the system aims to create a common, tamper-resistant reference for both sides of the ad market.
Glossary: Arbitrum is a layer-2 scaling network for Ethereum that processes transactions off the main blockchain to achieve lower fees and faster confirmation, then posts the results to the mainnet.
Steven Goldfeder, co-founder and CEO of Offchain Labs, stated that advertising has traditionally been measured by impressions, but the industry is moving toward verifiable performance. Goldfeder believes blockchain provides the right framework for this evolution.
Goldfeder stressed that markets and transactions now operate automatically through software, and the ability of every participant to verify cryptographic proofs is starting to reshape the advertising sector as well.
In the context of the pilot, Arbitrum’s infrastructure allows LG to configure the execution environment, fee model, and governance settings according to its objectives, while avoiding having the system under the control of a single company. Offchain Labs CTO Harry Kalodner added that large enterprises want the guarantees of public infrastructure without sacrificing control over their own operations.
Expansion to live ad environments next
LG’s stated strategy is that the system will not replace existing demand-side or supply-side ad platforms. Instead, the verification layer is intended as a complementary component within the current advertising tech stack. The goal is to keep transition costs low and preserve existing working relationships between advertisers and publishers.
Brendan Ma, Head of Investment Strategy at the Arbitrum Foundation, noted that since Arbitrum’s launch, corporate interest has grown across sectors including finance and transaction services. LG, for its part, plans to expand the system to broader live ad environments in the next phase, with a focus on improving data reliability, privacy, and cost efficiency through technical standards.
