The sustainability of higher education systems increasingly depends on the integrity, transparency, and long-term verifiability of academic credentials. Widespread diploma fraud, unauthorized modification of academic records, and fragmented verification mechanisms undermine institutional trust, graduate mobility, and public confidence in educational outcomes. These challenges directly affect the social and governance dimensions of sustainable development, particularly in the context of universities’ digital transformation. This study proposes a blockchain-based approach to support sustainable governance of academic documents by strengthening transparency, accountability, and auditability. The proposed system employs cryptographic hash anchoring and smart contract–based enforcement to verify academic credentials such as diplomas, transcripts, and certificates. Document contents are processed and stored off-chain, while cryptographic representations and essential metadata are immutably recorded on an EVM-compatible blockchain, ensuring data privacy and resistance to tampering. Any modification to a document results in a mismatch between the original and recomputed hashes, making fraudulent alterations immediately detectable. A web-based application and a role-restricted smart contract were implemented to support document issuance, verification, and immutable audit logging. System evaluation based on blockchain transaction evidence confirms reliable document registration, deterministic verification outcomes, and verifiable linkage between institutional actions and on-chain records. The results indicate that blockchain-based document verification can contribute to the reduction in corruption risks and improve transparency, strengthening institutional trust and supporting sustainable digital governance in higher education systems.
