“…• Swarm, is a peer to peer protocol, which stores data in an unchangeable form. It runs on the Ethereum platform [16]. • Cassandra, is a NoSQL database, which is based on the addition of more nodes for data storage, which is actually known as the continuation of SQL databases, and those who are familiar with it, find it very easy to use Cassandra.…”

“…Very important for the efficient generation of diplomas, is the insertion of data in a detailed form in the system, taking special care for all information not to be mistaken, because every mistake has its own cost in the blockchain system. It is of little importance whether Homomorphic Encryption, Zero-Knowledge Proofs or Elliptic Curve Cryptography will be used, as they aim to preserve data security, privacy, collaboration and database management in a protected way [16]. The digital signature is very important during the insertion of the data in the database, as the same must be signed at the end by the student but also by the institution's management.…”

The management of data and their storage in the database for an indefinite time, whether in a centralized or decentralized form, is of great importance for the operation of the system and its efficiency. One of the challenges that decentralized systems are facing is the lack of decentralized management of databases, because they have limitations in terms of inserting, updating, and deleting data. The generation of diplomas is a more sensitive issue and one of the reasons why it has not been digitalized to date is the fact that centralized systems do not offer sufficient security for the generation of such documents, since the same systems must be controlled by third people or administrators of the system, where there is also the suspicion of data misuse. Through the paper, we will compare centralized and decentralized databases, the operation of decentralized databases, and finally present a scheme of our vision about the operation of the database in the blockchain-based system for the generation and verification of diplomas.

Nowadays, the centralized systems used in higher education institutions are sophisticated and have high security mechanisms, offering secure data transfer and real-time encryption. Despite the prevalent usage of centralized systems in many institutions, particularly those within the realm of higher education, some unresolved concerns persist pertaining to privacy, potential abuse, transparency, and the limited capacity to digitize numerous services. Blockchain systems are considered as a potential solution for addressing these constraints. This study begins by highlighting the significance of implementing blockchain systems in higher education institutions, while also outlining the obstacles encountered by researchers in this domain. Centralized systems and blockchain systems are distinguished, with a description of the challenges related to data transfer and adaptation to different platforms. A thorough explanation of the proposed blockchain system begins with a presentation of the conceptual model, followed by a detailed architecture of the processes that would be executed by the system, with particular emphasis on the generation and authentication of academic credentials. Additionally, an analysis is provided on the significance of smart contracts in the programming of blockchain systems. This includes a detailed explanation of the main smart contract architecture used in the proposed blockchain system. This article aims to explore the development of a proposed blockchain system and its practical implementation for testing purposes using specific scenarios and data in the foreseeable future.
