[Edaily An Yu-ri Reporter] FASOO AI announced on the 25th that it has implemented a private blockchain system for Donghaeng Lottery’s lottery data.

By applying the private blockchain solution “FasooBlock” across Donghaeng Lottery’s entire lottery system, the company aims to prevent the forgery or tampering of lottery data and ensure its integrity and transparency.

FASOO AI, a member of the Donghaeng Lottery Consortium—the fifth-term lottery trustee—is responsible for the overall security of the lottery business. Going a step further, FASOO AI has introduced blockchain technology across the entire lottery system to achieve the consortium’s system enhancement goal of “strengthening the integrity of lottery data and ensuring stability.”

Private blockchains restrict participation to authorized users, enabling fast processing speeds and access control for sensitive data. For this reason, they are primarily used in scenarios where multiple entities—such as in supply chains or collaborative projects—jointly manage data and require proof of authenticity and traceability.

PasuBlock provides data integrity and confidentiality through this private blockchain approach. It is applied to all of Donghaeng Lottery’s draw-based lotteries—such as “Lotto 6/45” and “Spitto 2000”—as well as instant lotteries, securely recording and managing integrity hashes (data integrity checksums) for purchase ledgers and winning information.

Furthermore, it strengthens data integrity and the reliability of verification by applying additional verification procedures using this information, particularly when verifying high-value tickets. Since the history recorded on the blockchain is traceable and virtually impossible to falsify or alter, it enhances the transparency of lottery management and helps combat fraudulent sales and counterfeit lottery tickets.

Lim Cho-soon, Head of the Donghaeng Lottery System Operations Division, stated, “The reliability and transparency of lottery data are crucial elements for stable lottery operations,” adding, “Through our collaboration with FASOO AI, we have further strengthened our data management system, and we will continue to build a stable lottery operating environment that the public can trust.”

Kang Bong-ho, Head of the Service Business Division at FASOO AI, remarked, “PasuBlock, based on private blockchain technology, is a cost-effective and efficient solution for ensuring data reliability and transparency.” He continued, “Building on this Donghaeng Lottery project—which was implemented through joint design with the operating consortium—FASOO AI will expand the application of PasuBlock to various industries where data integrity is critical, such as finance, the public sector, and logistics.”
