Abstract—Advancements in digital technologies have made
the storage, sharing, and verification of educational credentials
extremely important for entities such as students, universities,
institutions, and companies. Digital credentials play an
important role in students’ lives as a lifelong learning passport.
The educational field is experiencing numerous issues such as
academic record forgery, record misuse, credential data
tampering, time-consuming verification procedures, and issues
related to ownership and control. Modern-day technology,
Blockchain, is an appropriate alternative to resolve these issues
and increase trust among entities. In this research, we intend to
propose a Blockchain-based educational digital credential
issuance, and verification model that addresses these issues in
the education system using Ethereum Blockchain and smart
contracts. The method we propose offers a way to demonstrate
the correctness of specific credential attributes without
revealing other attributes, thereby leading to ownership,
minimal disclosure, and control. We offer an interface for
storing massively encrypted academic records in a decentralized
file system like Interplanetary File System (IPFS). Furthermore,
Ethereum provides tamper-resistant chains to maintain the
integrity of digital credentials. Finally, in comparison with the
time it requires to issue credentials, our model safely accelerates
the verification process by about 8%.
Index Terms—Blockchain, Ethereum, interplanetary file
system, smart contract, digital credential
