FasooAI has deployed FasooBlock, its private blockchain solution, across the lottery systems operated by Donghaeng Lottery, in a move aimed at strengthening data integrity, transparency and security across key lottery operations.

FasooAI belongs to the consortium that operates Donghaeng Lottery — the country's fifth lottery outsourcing operator, in place since December 2023 — and is responsible for overall lottery security. The latest deployment introduces private blockchain technology as part of a broader effort to improve the reliability and stability of the lottery system, particularly in areas where accurate data management and verification are critical.

The technology has been applied to Donghaeng Lottery's draw and instant lottery systems, including Lotto 6/45, the twice-weekly number draw that ranks among the country's most widely played lottery games, and Speetto 2000, an instant scratch-style ticket. FasooBlock records purchase ledger integrity hashes and winning information on a blockchain, enabling authorized participants to verify whether stored information has been altered — an additional layer of protection for important lottery records.

Unlike public blockchain networks, private blockchains restrict participation to authorized users. This structure allows organizations to control who can access information while maintaining a traceable record of changes, a design that is particularly useful in environments where multiple parties share responsibility for data — as at Donghaeng Lottery, where operations are handled by a consortium of companies — and require mechanisms to establish authenticity and track historical changes.

Blockchain Verification for High-Value Tickets

FasooAI has also incorporated blockchain-based information into the validation process for high-value lottery tickets. The additional verification stage compares ticket-related information against records maintained on the blockchain.

According to the company, the approach makes it more difficult to manipulate lottery data while improving operators' ability to respond to suspected fraudulent sales and counterfeit tickets. By introducing an independently verifiable record into the validation process, the technology is intended to reinforce confidence in the accuracy of lottery-related information.

Reliable records are essential for lottery operators because purchasing, drawing and prize validation processes all depend on the accuracy of underlying data. Any unauthorized alteration could affect verification procedures or undermine public confidence, and the deployment therefore forms part of a wider effort to strengthen safeguards around critical operational information. That confidence also carries stakes beyond the games themselves: in South Korea, lottery proceeds are channeled into a public lottery fund that finances welfare, housing and cultural programs, so the integrity of draw and prize records underpins publicly funded spending as well.

Reliability and Public Trust in Focus

Lim Cho-soon, head of the System Operations Division at Donghaeng Lottery, said the reliability and transparency of lottery data are central to maintaining stable operations. She indicated that the collaboration with FasooAI had further strengthened the organization's data management capabilities and that Donghaeng Lottery would continue working toward a stable operating environment that the public could trust.

FasooAI executive Kang Bong-ho, head of the Service Business Division, described FasooBlock as an economical and efficient approach to improving data reliability and transparency through private blockchain technology. He indicated that the Donghaeng Lottery deployment could serve as a foundation for expanding the solution into other industries where maintaining data integrity is particularly important.

FasooAI plans to use the lottery project as a reference case for broader blockchain applications in sectors such as finance, government services and logistics, where accurate records and verifiable data histories are increasingly important.

The deployment illustrates how private blockchain technology can be applied beyond cryptocurrency use cases. By combining controlled access with tamper-evident records and additional verification mechanisms, the technology can support organizations that need to protect sensitive operational data while maintaining accountability among authorized participants.

The Donghaeng Lottery implementation also demonstrates a practical use of blockchain for strengthening existing systems rather than replacing them. Its focus on data verification, fraud prevention and operational stability could provide a model for other industries seeking to improve trust in shared digital records, with the lottery deployment serving as the working test case for how the approach performs in day-to-day operations.
