【Abstract】Bachelor's diplomas are the most frequently forged documents, followed by high-school diplomas. The document is vital for admission, hiring, and citizenship, and the digital version allows easy access and uses, although it suffers from forgery and falsification. The establishment of blockchain technology enables the creation of diplomas as digital assets and the distribution of them confidentially and securely through a peer-to-peer network. This study aims to develop an application that utilizes a private blockchain for creating digital assets based on diplomas and storing, distributing, and managing them. Blockchain Lisk is chosen in this study with the Delegated Proof of Stake consensus protocol for implementing the application as a proof-of-concept. Actual diplomas from Universitas Multimedia Nusantara (UMN) are used in this study to design, implement, test, and evaluate the application. Evaluation of the security aspect of the application is measured using computer security base metrics: the common configuration scoring system (CCSS). This study shows that private blockchain technology stores distribute and manage diplomas securely and at no cost by eliminating fees and incentives. The actual security level of the application at UMN scored using CCSS obtained a BaseScore of 3.3, categorized as low vulnerability severity.
