Creative Economies Need Financial Infrastructure First

**Optimism is making moves in Korea's financial sector.** Kyle Jenke from the Optimism team appeared on Hankyung TV to discuss OP Enterprise and its role in helping Korean financial institutions integrate blockchain technology. **Key developments:** - The Optimism team spent the week in Korea exploring onchain finance opportunities for the country's financial system - Discussion centered on a proof-of-concept for a Korean won stablecoin built on the OP Stack - Partnership with Toss, a major Korean fintech company, on the stablecoin initiative OP Enterprise appears designed to lower technical barriers for traditional financial institutions looking to adopt blockchain infrastructure.

**Toss, South Korea's dominant payment platform serving two-thirds of the country's population, is exploring putting the won onchain.** The financial technology company is investigating blockchain integration for the Korean currency. This move could represent a significant step toward mainstream adoption of onchain finance in one of Asia's most technologically advanced markets. Toss's exploration comes as the company continues to dominate South Korea's digital payment landscape. The platform's massive user base positions it as a potential bridge between traditional finance and blockchain technology. Details about the implementation timeline and technical approach are outlined in [Optimism's blog post](http://optimism.io/blog/two-thirds-of-south-korea-runs-its-money-through-toss-now-toss-is-exploring-putting-the-won-onchain).

**South Korea's largest fintech app Toss is exploring an onchain Won stablecoin in partnership with Optimism.** Toss serves over 30 million users—two-thirds of South Korea's population—who manage banking, payments, investing, credit, and taxes through the platform. **Key implications:** - Korea has 16 million active crypto traders, creating significant existing demand - A Toss-sized stablecoin would become one of the largest regulated onchain money experiments globally - The stablecoin would operate within an app most Koreans already use daily The memorandum of understanding (MOU) between Toss and Optimism marks a potential shift toward mainstream blockchain adoption in one of crypto's most active markets.

A proof-of-concept test is underway for a Korean Won-backed stablecoin that combines regulatory compliance with blockchain privacy. **Key Components Being Tested:** - OP Enterprise for settlement control - KYC and AML systems built to Korean regulatory standards - Sunnyside Labs' @PrivacyBoost for private transactions on public networks The test, involving Optimism, @PrivacyBoost, and @toss__official, runs over three months to determine if digital money can settle onchain while meeting Korea's requirements for compliance, privacy, and institutional control.

Optimism explores how blockchain adoption will reach a billion users not through hype, but through invisible integration into everyday applications. **Key insights:** - Mass adoption won't announce itself - users will interact with blockchain technology without realizing it - The focus shifts from crypto-native applications to embedding blockchain infrastructure into mainstream services - Success means the technology becomes invisible, working seamlessly in the background - Optimism positions itself as the scaling solution enabling this quiet revolution Read the full analysis: [The Billion User Moment](https://optimism.io/blog/the-billion-user-moment-nobody-will-see-coming)
