LG Electronics is bringing blockchain technology to the digital advertising industry through a new platform built on Arbitrum. The South Korean consumer electronics giant says the system will automate the buying and selling of advertisements and create a shared on-chain record of ad inventory and user interactions. After completing an initial pilot with a Japanese advertising agency, LG plans to explore a commercial launch later this year.

LG Builds a Blockchain Network for Digital Advertising

According to a June 11 report, LG Electronics has developed its own Layer 2 blockchain using Arbitrum’s Ethereum (ETH) scaling technology to power a blockchain-based advertising marketplace.

Rather than focusing on cryptocurrencies, the network aims to streamline programmatic advertising by giving advertisers and publishers access to a shared database of available ad inventory as it records how users interact with advertisements.

The platform is intended to automate much of today’s advertising marketplace through smart contracts, reducing manual negotiations and improving transparency between participants. Samuel Byungsun Park, who leads LG Electronics’ blockchain research department, said:

“We are evaluating whether this approach can deliver meaningful value to advertisers, publishers and audiences.”

Arbitrum co-founder Steven Goldfeder said blockchain technology can remove friction from the advertising process by allowing automatics handling of transactions. As Goldfeder explained:

“It means that you can basically run the market in an automated way in software. (…) You don’t need manual interventions.”

LG has already tested the platform with an unnamed Japanese advertising agency and plans to evaluate wider commercialization later in 2026.

Enterprise Blockchain Adoption Continues to Expand

The project reflects a growing trend of large corporations developing their own blockchain infrastructure for enterprise applications instead of consumer crypto products.

Fortune noted that Stripe is developing its Tempo blockchain alongside Paradigm, whereas Circle is building its Arc network and Robinhood is collaborating with Arbitrum on a blockchain for tokenized equities.

Unlike many earlier corporate blockchain experiments, LG’s initiative targets an existing multibillion-dollar business where automation and transparency could reduce costs for both advertisers and publishers.

The company has invested in blockchain research for several years through a dedicated research lab and has previously explored Web3 products, including NFT marketplaces and digital wallet technology.

Goldfeder cautioned that launching a blockchain is not the right solution for every company. However, he argued that businesses operating complex digital marketplaces, such as online advertising, can benefit from blockchain infrastructure when it meaningfully improves efficiency and reduces operational overhead.

If the platform reaches commercial deployment, it would represent one of the largest real-world enterprise blockchain applications from a global consumer electronics manufacturer, and demonstrate how distributed ledger technology continues expanding beyond cryptocurrencies into traditional business infrastructure.
