Comprehending these principles is pivotal to comprehend how blockchain functions as a decentralized and widely distributed digital ledger. Subsequently, the segment delves deeper into blockchain technology’s essential attributes and distinguishing traits that render it exceptionally well-suited for diverse applications, including education. It scrutinizes the importance of transparency, decentralization, immutability, security, and efficiency in tackling the obstacles encountered by conventional educational systems and fostering avenues for innovation. Moreover, a comprehensive examination is presented regarding the distinct categories of blockchain networks, encompassing public, private, and consortium blockchains. Furthermore, diverse consensus mechanisms such as Proof of Work (PoW), Proof of Stake (PoS), and Practical Byzantine Fault Tolerance (PBFT) are deliberated upon. Grasping the assortment of blockchain networks and consensus mechanisms is vital in assessing their pertinence and suitability within education.

1.2.1 Definition and Basic Concepts of Blockchain To grasp the potential influence of blockchain technology in education, it is vital to have a solid understanding of its foundational principles. This section comprehensively elucidates blockchain and delves into its fundamental constituents. Blockchain, a digital ledger that operates in a decentralized and distributed manner, is responsible for documenting transactions across multiple computers or nodes [1]. Its design emphasizes transparency, security, and immutability, providing a sturdy framework for diverse applications beyond cryptocurrencies. In contrast to conventional centralized systems, where data are stored and managed by a central authority, blockchain enables a distributed network of participants to uphold and authenticate the ledger collectively. To gain a deeper comprehension of blockchain, let us delve into its fundamental constituents: Blocks Within the realm of blockchain, data are structured into blocks, each encompassing a compilation of verified transactions that are appended to the ledger [2]. The block structure plays a pivotal role in organizing and efficiently storing data, facilitating the grouping of transactions, and streamlining their processing and validation procedures.

1.2  Introduction to Blockchain Technology

Moreover, every individual block within the blockchain possesses an exclusive identifier called a hash. A hash is a cryptographic value of fixed length that is produced using mathematical algorithms [3]. It serves as a representation of the entire content within the block, functioning as a digital fingerprint. Even a minor alteration in the data within a block would lead to an entirely distinct hash value [4]. This characteristic identifies any tampering or unauthorized changes to the block’s content. Transactions Transactions are the foundational units of activity documented on the blockchain, representing the actions or operations executed within the blockchain network [5]. They encapsulate various activities, such as financial transactions, data transfers, or any other type of digital interaction. Each transaction contains pertinent information, including sender and receiver addresses, timestamps, and transaction particulars. When a participant starts a transaction, it undergoes a validation procedure to ascertain its legitimacy and integrity. This verification process usually entails confirming that the transaction complies with predetermined rules and that the sender possesses the required permissions or funds to execute the transaction. Once validated, the transaction is appended to a block, thus becoming part of the blockchain. Cryptographic Hashing Cryptographic hashing is a fundamental operation utilized in blockchain to guarantee the integrity and security of data. It entails transforming input data of any magnitude into a string of characters with a fixed size, known as a hash [6]. Cryptographic hashing functions are engineered to be rapid and effective, producing distinct hash values for varying input data. The hash generated by the cryptographic function is unidirectional, making it exceedingly challenging to deduce the original input data solely from the hash. This attribute augments the security of the blockchain since the hash functions as a digital fingerprint for the content within the block. Any endeavor to modify the block’s data would yield an entirely distinct hash, promptly indicating tampering or unauthorized alterations [7]. Chain of Blocks The series of blocks, commonly known as the blockchain, is a sequential order of interconnected blocks. Every block in the chain references the preceding block’s hash, establishing a connection between the blocks. This linkage guarantees the integrity and unchangeability of the data within the blockchain [8]. Adding a new block to the blockchain incorporates the preceding block’s hash, consequently creating a chain. This interconnectedness renders it computationally unviable to modify a solitary block without necessitating alterations to all subsequent blocks. To modify a block, an attacker must recalculate the hash of the altered block and all subsequent blocks since any modification in the data would result in a distinct hash. Consequently, the distributed structure of the blockchain ensures a high level of security, as altering the entire chain becomes virtually unfeasible.

2.8 Privacy and Data Protection Considerations While a decentralized database of educational credentials enabled by blockchain technology presents numerous advantages, it also raises significant privacy and data protection considerations [20]. This section will delve into the measures that can be implemented to address privacy concerns and ensure compliance with data protection regulations. It will also explore the balance between the need for transparency and protecting sensitive personal information and the utilization of encryption techniques and privacy-preserving mechanisms within the blockchain network. 1. Resolving privacy concerns and adhering to data protection regulations: Safeguarding privacy is paramount when dealing with personal information and educational credentials. To address these concerns, implementing the blockchain-based database must adhere to pertinent data protection regulations, such as the General Data Protection Regulation (GDPR) in Europe or equivalent laws in other regions [21]. This adherence entails obtaining informed consent from individuals whose credentials are being recorded on the blockchain. Users must be informed about the data being collected, stored, and processed and have the right to control and access their data. Additionally, data retention policies should be established to ensure that data is not retained longer than necessary for verification purposes. 2. Balancing transparency and protecting sensitive information: Blockchain’s inherent transparency and immutability can pose challenges when handling personal and sensitive information. While transparency is crucial for verifying credentials and building trust, it is vital to balance transparency and safeguarding sensitive data. Blockchain networks can use data masking or tokenization to achieve this balance. Data masking involves encrypting sensitive information, such as Social Security numbers or addresses, so only authorized parties can access the decrypted data. Conversely, tokenization replaces sensitive data with random tokens, rendering the original information indecipherable without access to the decryption key. 3. Encryption techniques and privacy-preserving mechanisms: Blockchain networks can implement data encryption and privacy-preserving mechanisms to

enhance data privacy. End-to-end encryption ensures that data are encrypted at the source and decrypted only by the intended recipient. In the context of the blockchain, this can be applied to communications between network participants, guaranteeing that sensitive data remains confidential. Zero-knowledge proofs (ZKPs) are another privacy-preserving mechanism that can be utilized [22]. With ZKPs, a party can prove the authenticity of certain information without revealing the actual data. For instance, an educational institution can prove that a degree was awarded to a student without disclosing the specific details of the degree. 4. Role-based access control: Role-based access control (RBAC) is an essential mechanism for preserving privacy within the blockchain network [23]. RBAC guarantees that each participant receives access rights based on their designated role and authority. For instance, employers may be granted permission to access specific information relevant to their hiring process, while other parties may have more limited access. 5. Private and permissioned blockchains: In scenarios where stringent privacy requirements are essential, a private or permissioned blockchain can be employed [24]. Private blockchains restrict access to a select group of known participants, guaranteeing that only authorized parties can access the data in the network. Overall, privacy and data protection play crucial roles when deploying a blockchain-­based database for educational credentials. Complying with data protection regulations, including obtaining informed consent and establishing data retention policies, is fundamental. Encryption techniques, data masking, tokenization, ZKPs, and RBAC can be utilized to strike a balance between transparency and safeguarding sensitive information. Furthermore, private or permissioned blockchains can enhance data privacy for applications requiring strict privacy measures. By meticulously considering and implementing these privacy-preserving measures, the blockchain-based database can maintain the confidentiality of sensitive information while ensuring transparency and trust in the verification process.

41

cooperate, and conduct transactions directly among themselves, thereby cultivating a more comprehensive and varied ecosystem.

3.3.2 How Blockchain Technology Works Blockchain serves as the foundational technology for numerous decentralized systems, functioning as a distributed ledger. It comprises a sequence of blocks, with each block encompassing a set of transactions [6]. These blocks are interconnected through cryptographic mechanisms, creating a chain, and they are spread across a network of nodes (computers) that engage within the blockchain network. The sequence initiates when a participant in the network suggests a transaction. This transaction is authenticated and combined with other transactions to form a block. Prior to incorporating a block into the chain, it must undergo validation through a consensus mechanism, whereby network nodes concur on its legitimacy. Upon endorsement, the block is assigned a timestamp and appended to the blockchain, transforming into an unchangeable and fixed record. The inherent decentralization of the blockchain guarantees that no singular entity possesses the ability to modify or erase previous transactions, thereby upholding the integrity and openness of the entire system. Additionally, the consensus mechanism guarantees that all participants arrive at a shared accord regarding the state of the blockchain, preventing malicious entities from tampering with the data.

3.3.3 Blockchain’s Role in Decentralized Marketplaces Blockchain technology holds a pivotal role in creating and managing decentralized educational resource marketplaces [7].
