South Korean Consortium Demonstrates Scalable Digital Money Platform
The initiative is part of a growing number of digital coin and fiat-pegged stablecoin experiments within South Korea’s digital assets industry.
South Korea Expands Stablecoin and Digital Currency Testing
Completed by K STAR and BNK Busan Bank, the PoC trial managed to achieve a 100% transaction success rate. Recorded for 24 hours, processing speeds were under one second.
The PoC showed that the tested features allow issuers to enforce spending conditions, including restricting funds to approved merchants only, or setting automated expiry dates for balances that are unused.
The consortium states that the final technology can be useful for automated government subsidiaries, regional shopping vouchers, central bank digital currencies (CBDCs), and won-backed stablecoins.
PoC Validates End-to-End Infrastructure
The PoC trial was organized by the K-STAR consortium and BNK Busan Bank, and successfully moved beyond simple transfers on the blockchain towards “programmable money.” The proposed system was tested against real transaction volumes, which were modelled after BNK Busan Bank’s current payment operations. The success of the trial shows that localized digital assets can handle heavy market traffic in addition to offering advanced policy controls regarding public funds.
The success of the PoC is the result of a collaborative effort: while BNK Busan Bank designed the core financial model, AhnLab Blockchain Company was responsible for building the Web3 wallet and transaction infrastructure. The issuance of the won-pegged stablecoin was handled by OpenAsset, Kaia provided the Layer 1 mainnet, and Lambda256 oversaw the operations of the crypto nodes.
South Korean Consortium Tests Programmable Digital Money Beyond Basic Blockchain Payments
The consortium did not limit the PoC to basic payments on the blockchain, but tested whether programmable digital money could enforce predefined policy rules. The results approve that the issuers can:
- Configure the digital currency to be only spent at approved merchants
- Set expiration dates after which unused balances become automatically invalidated
- Apply different settlement conditions based on merchant categories
The trial also assessed how operational the platform remains under realistic conditions. The consortium used transaction volumes modelled on BNK Busan Bank’s current payment network to evaluate performance under normal operating conditions, periods of congestion, peak transaction times, and irregular patterns. According to K-STAR reports, all transactions were processed successfully.
Stablecoin Projects Advance as South Korea Prepares New Digital Asset Legislation
The latest effort is part of South Korea’s project centering on blockchain-based payment systems, as well as the country’s upcoming digital asset legislation.
In 2025, Upbit operator Dunamu announced a partnership with Naver Pay aimed at supporting the development of a won-backed stablecoin. Following President Lee Jae-myung’s encouragement for private companies to issue won-backed stablecoins, the project gained further momentum. Around the same time, much like the leading banks in Japan working together to launch a stablecoin, South Korea’s major banks announced a joint stablecoin initiative. The K-STAR trial comes after several recent blockchain payment initiatives by South Korean financial institutions. Earlier this year, KB Financial Group and Shinhan Card separately tested won-backed stablecoin payments, retail transactions, and cross-border transfers as the country prepares its new digital asset regulations.
