Case Study: Dain Leaders achieves secure, faster international admissions with Oracle Blockchain on Oracle Cloud Infrastructure

Edutech firm creates blockchain service with Oracle Cloud

Dain Leaders is a Korea-based edutech specialist whose DoDream platform helps international students find courses, services, and admissions support for studying at Korean universities. Students faced information gaps and a confusing admissions process, while universities struggled to find, evaluate, and authenticate applicants; earlier reliance on commercial software and internal hosting produced slow performance and operational friction.

Dain Leaders implemented DoDreamChain on Oracle Cloud Infrastructure using Oracle Blockchain Platform, a permissioned blockchain that simplified development and integration and enabled a SaaS delivery model. The move reduced working time and optimized performance for universities, accelerated time-to-market, lowered blockchain management effort, and improved secure verification of student applications — streamlining international admissions and easing administrative burdens.
