LG Electronics, Arbitrum Launch Blockchain Ad Network

Crypto Insight Summary: LG is building a blockchain focused on buying and selling ads, joining a wave of companies launching their own blockchains in recent years. South Korean tech giant LG Electronics is working with the Ethereum layer-2 network Arbitrum to build a blockchain-based advertising network aimed at serving the digital ad industry. Arbitrum would give advertisers and publishers a shared database of ad inventory and track how customers interact with advertisements, with the company exploring how to bring the service to market this year, Fortune [reported](https://fortune.com/2026/06/11/lg-electronics-blockchain-arbitrum-ad-advertisements-platform/) on Thursday. “We are evaluating whether this approach can deliver meaningful value to advertisers, publishers and audiences,” said Samuel Byungsun Park, the head of LG Electronics’ blockchain research lab. _LG Group’s headquarters is in Seoul, South Korea.

Traditional ad networks require costly intermediaries to automate and manage the buying and selling of ad space between advertisers and publishers. “It means that you can basically run the market in an automated way in software,” Arbitrum co-founder Steven Goldfeder told Fortune. In 2018, LG CNS, a subsidiary of the LG Corporation, launched an in-house blockchain called “Monachain” aimed at businesses that could be used for digital authentication, payments and supply chain management. LG Electronics developed a decentralized crypto wallet called Wallypto using the [Hedera Hashgraph network](https://cointelegraph.com/news/archax-launches-real-time-yield-payments-for-tokenized-securities-on-hedera) at the height of the 2022 NFT boom. Crypto Insight Analysis: Direction: Neutral Impact: Minor Impact Horizon: Mid-term (1-8 weeks) Reasoning: LG's ad network is niche and unlikely to significantly impact broader crypto markets.
