LG partners with Arbitrum to build blockchain advertising platform

LG Electronics is developing a proprietary layer‑2 blockchain with Ethereum scaling solution Arbitrum to streamline digital advertising [1]. The platform will let advertisers and publishers share a single database of ad inventory and record user interactions, with a commercial evaluation slated for later this year [3].

Key takeaways

• LG built its own L2 network on Arbitrum to enable low‑cost, high‑throughput ad transactions [1]
• The system creates an immutable ledger of ad slots, impressions and engagements [3]
• A pilot with an unnamed Japanese ad agency has been completed; a broader rollout is planned for 2026 [3]
• LG’s blockchain research lab leads the effort, headed by Samuel Byungsun Park [1]
• Arbitrum co‑founder Steven Goldfeder says the platform could automate ad markets without manual intervention [1]

Building a custom L2 for programmatic ads

Fortune reported that LG’s blockchain research department collaborated with Arbitrum to construct a dedicated layer‑2 network that batches transactions cheaply, a key requirement for the high‑volume nature of programmatic advertising [1]. The architecture stores a shared, on‑chain database of ad inventory and tracks how customers interact with each ad, allowing smart contracts to automate buying and selling processes [3]. LG’s internal lab, which has previously piloted the technology with a Japanese advertising agency, is now moving beyond technical testing toward a commercial evaluation slated for later in 2026 [3].

Arbitrum’s co‑founder Steven Goldfeder highlighted the efficiency gains, noting that the platform can “run the market in an automated way in software” and eliminate the need for manual negotiations [1]. LG’s head of blockchain research, Samuel Byungsun Park, echoed this sentiment, saying the company is assessing whether the approach can deliver meaningful value to advertisers, publishers and audiences [1].

Corporate blockchain trends and LG’s broader strategy

LG’s move reflects a growing willingness among large enterprises to launch their own blockchains amid a more favorable regulatory climate in the United States [1]. Other firms such as Stripe, Circle and Robinhood have pursued similar projects, often partnering with Arbitrum or other layer‑2 solutions [1]. LG’s initiative aligns with its decade‑long corporate roadmap that includes earlier blockchain efforts like the 2018 “Monachain” enterprise ledger and the 2022 amendment of its charter to permit blockchain‑based software development and cryptocurrency brokerage [3].

Why it matters

If successful, LG’s blockchain advertising platform could provide a template for other media and technology companies seeking to reduce fraud, improve transparency and lower costs in the $679 billion digital ad market [4]. The rollout will test whether a custom L2 can handle the scale of LG’s global smart‑TV base—approximately 216 million units worldwide—and deliver the promised automation benefits. The next steps involve a commercial evaluation later in 2026, after which LG may expand the service to broader advertising ecosystems.
