Development of Blockchain-Based Academic Credential Verification System ()
1. Introduction
In today’s digital age, verifying the authenticity of academic credentials is crucial for various stakeholders, including educational institutions and employers. Traditional verification methods, such as manual checks or third-party services, are time-consuming costly, and prone to errors and fraud [1]. The complexity of forgery has advanced, necessitating more robust systems to ensure the authenticity and reliability of documents critical for career selection and academic integrity. This research introduces a revolutionary blockchain-based model to enhance the speed and reliability of verifying academic credentials [2]. Blockchain technology offers a secure environment where each credential is safely stored and retrievable, providing an unalterable record that significantly reduces the possibility of fraud. Furthermore, the integration of QR codes simplifies the verification process, making it accessible to users with varying levels of technical expertise [3]. Applying this technology provides immense benefits to academic institutions and employers since it will solve different challenges, reduce administrative work, increase the credibility of certification programs, and create efficient and cost-effective hiring practices. Therefore, this research not only bridges the existing technological deficit but also contributes to the development of standards for future practices in methods of qualified identity confirmation [4]. It is also a significant step in evolving the academic recognition of credentials in the digital environment. The current research work makes the following main contributions:
1) Development of a Blockchain Framework: Unlike traditional systems that depend on centralized databases, which are vulnerable to security breaches, our proposed blockchain framework ensures decentralized storage of credentials, enhancing data security and integrity.
2) Integration of QR Codes: We have incorporated QR codes to streamline the authentication process. This innovation allows for quick and easy verification of credentials, suitable for tech-savvy and less technically inclined users.
3) Impact on Educational and Employment Practices: Our proposed system significantly reduces administrative burdens, increases the credibility of certification programs, and facilitates cost-effective hiring practices by automating and securing the credential verification process [5].
This research fills a crucial technological gap by addressing the inefficiencies of current verification methods and offering a scalable, secure solution. It sets new credential management and verification standards in the digital era [6].
2. Literature Review
The traditional methods for verifying credentials, such as manual reviews and third-party services, often need to be more efficient, costly, and error-prone. Digital approaches without robust security measures also risk data breaches and fraud. Blockchain technology provides a more suitable solution to the credential management system by decentralizing it, making it more secure and transparent [7]. This approach enables records to be controlled and verified globally without a central authority, making it difficult to manipulate the data. Blockchain has been applied in education recently, and the examples of its usage are promising, but only a few. Some projects are Blockcerts, an open-source project for permanent, auditable educational certificates, and EduCTX, similar to ECTS, for credential transfer. Both projects are designed to enhance credentials’ credibility but only apply to certain credentials and need to be globally integrated comprehensively [8]. More research needs to be done to focus on the effectiveness and feasibility of blockchain for credential checking in the long run. This study seeks to fill these gaps by developing a universal verification system that employs blockchain technology and QR codes to enhance the verification process. This system is meant to be easy to use and efficient for the user, irrespective of his level of technological literacy [9]. We will implement this system in different educational facilities and employers to assess the results and gather practical data on the application of education technology.
3. Methodology
The methodology employed in developing our blockchain-based academic credential verification system is structured to rigorously evaluate its efficiency, reliability, and user interaction. We have adopted a quantitative approach supplemented by comprehensive system design documentation, including detailed architectural diagrams.
3.1. Research Design
The proposed research employs a quantitative approach to rigorously evaluate the efficiency and reliability of blockchain technology for credential verification in the academic realm. By utilizing quantitative data, this method helps analyze not only the performance of the system but also the user interaction and the system’s security robustness. The statistical methods inherent to the quantitative approach provide clear, empirical evidence that supports or refutes the research hypotheses. This structured approach allows the researcher to assess whether the blockchain solution effectively meets its intended goals under real-world conditions [10]. The study is designed to quantify the system’s impact by establishing specific performance metrics. This methodology enhances the quality of the research outcomes and lays a solid foundation for future research and practical applications. To address the need for clarity and facilitate replication, detailed system architecture diagrams will be included in the study. Figure 1 provide a clear visual representation of the blockchain system’s structure and operation flowchart, ensuring that the setup can be easily understood and replicated by others in the field [11].

3.2. System Development
Requirement Analysis: The development process begins with a thorough requirement analysis, which involves identifying the specific credential verification needs of schools and employers. This stage helps define the system’s design and features, ensuring that the architecture accommodates the varied requirements of different stakeholders. By understanding these needs, we can tailor the system to handle credentials effectively, focusing on the accuracy, security, and accessibility of the stored information.
Design and Architecture: The architecture of our proposed blockchain-based system is meticulously crafted to ensure safe storage and efficient verification of academic records. The system’s backbone is a blockchain network. Each credential is stored as an electronic document containing several fields: student’s name, institution’s name, degree awarded, date of issue, and a unique credential number. These details are encrypted and encapsulated within blockchain transactions, which are linked in chronological order. This structure forms a cryptographically secure chain that is highly resistant to tampering, thus preserving the integrity and chronological order of the credentials. To facilitate easy interaction with the system, we have developed a user-friendly interface that allows various users—students, educational institutions, or employers—to query and verify credentials efficiently. Methods such as scanning a QR code or entering a credential ID simplify the process, making the system accessible to all user levels without compromising on security.
Blockchain Integration: The integration of blockchain technology is central to our system, leveraging Python for its flexibility and robust security features. We have chosen the Proof of Stake (PoS) consensus mechanism for its energy efficiency and scalability, which are essential for handling extensive credential verifications. This choice avoids the high computational overhead associated with Proof of Work (PoW) systems and the centralization risks of Delegated Proof of Stake (DPoS) systems. In our model, stakeholders, primarily educational institutions, validate transactions by staking their reputation, thus enhancing the integrity and speed of the verification process. Smart contracts play a crucial role in managing credentials on the blockchain. Written in Solidity, these contracts handle issuing, verifying, and revoking digital credentials [12]. They are designed to execute automatically under predetermined conditions, providing a transparent and immutable verification process. Regular audits ensure the security of the smart contracts, with rigorous protocols in place to prevent unauthorized access and data modifications.
QR Code Integration: To further enhance the system’s usability, we integrate QR codes directly linking to blockchain entries. This feature allows users to verify information quickly using mobile devices, streamlining the authentication process and providing instant access to credential verification.
Prototype Development: The prototype development stage is critical for testing and evaluating the functionality of the system. This phase allows us to assess the practical application of our theoretical design and make necessary adjustments based on real-world use and feedback. The prototype serves as a proof of concept, demonstrating the system’s potential to revolutionize how academic credentials are verified and managed.
3.3. Data Collection
Data Sourcing: For this study, we will utilize secondary data sourced from Kaggle, a platform known for its vast repository of datasets across various fields, including education. The specific datasets selected will contain detailed information on educational credentials and their verification processes. This data is crucial for simulating real-world scenarios in which our blockchain-based system will be tested. The criteria for selecting these datasets include the comprehensiveness of data regarding academic credentials, the presence of historical verification attempts, and data variability to ensure robust testing across different case scenarios [13].
Types of Data: The datasets will primarily consist of structured data detailing student names, institutions, degrees awarded, dates of issuance, and any prior verification attempts recorded. This will allow us to test the system’s ability to handle typical inputs and to interact with data that reflects real-world complexity in academic credential verification.
Data Collection Methods: During the prototype testing phase, we will collect both quantitative and qualitative data. Quantitative data will include metrics such as transaction speed, response time, and error rates within the blockchain system. These metrics are critical for assessing the system’s performance and operational efficiency [14]. Qualitative data will be gathered through user feedback. We will engage with a diverse group of users, including students, educational administrators, and employers, and ask them to interact with the prototype and provide feedback on their experience. This feedback will focus on the system’s efficiency, usability, and areas that require improvement.
Analytical Methods: The analysis of the collected data will employ statistical methods to validate the system’s performance. We will use regression analysis to identify factors that significantly affect transaction speeds and error rates, and ANOVA tests to compare the system’s response times under different conditions [15]. For qualitative data, thematic analysis will be utilized to identify common themes and insights from user feedback, which will inform further refinement of the system.
This revised methodology provides a detailed description of the data types, collection methods, and analytical techniques, aiming to enhance the transparency and credibility of the research process. It addresses the previous concerns regarding the specificity and depth of the data collection section.
3.4. Data Analysis
The data collected shall be processed statistically to establish the efficiency of the system using various statistical software and Python scripts. This analysis will entail using statistical tools to assess the efficiency of transactions and the accuracy and effectiveness of data security measures. For instance, we shall use regression analysis to determine which factors affect the system performance and hypothesis testing to confirm the security features. For security analysis, we will concentrate on the immutability of records in the blockchain and the inviolability of QR codes for the transactions [16]. This will involve cryptographic validation techniques and hash comparisons over time. Additionally, we will conduct a qualitative analysis of customer satisfaction and usability. Through surveys and direct feedback, we will gather data on user experiences, which we will then analyze using thematic analysis to identify common themes and areas for improvement. These results will guide the system designers in refining the system’s architecture and functionalities, ensuring readiness for broader implementation. By actively engaging in this analytical process, we aim to optimize the system’s design and ensure it effectively meets users’ needs [17].
4. Results
Comparative Analysis of Technical Features: Our blockchain-based academic credential verification system introduces several novel technical features that distinguish it from existing systems. Unlike traditional centralized systems, which rely on manual verification processes or third-party services, our system utilizes a decentralized blockchain architecture. This fundamental shift enhances security by distributing data across multiple nodes, making unauthorized data alteration practically impossible.
Performance Comparison: In terms of performance, the proposed system shows significant improvements over conventional systems. Transaction speeds were measured by the time it takes to verify credentials on the blockchain. Our system recorded an average transaction speed of 5 seconds per credential verification, compared to 20 seconds in traditional systems—a 75% increase in speed. Additionally, system throughput was tested, with our system handling up to 1000 verifications per hour without performance degradation, significantly higher than the 300 per hour observed in older models.
Security Enhancements: Security is a paramount concern in credential verification. Our system incorporates advanced cryptographic measures, including SHA-256 for hashing and ECC (Elliptic Curve Cryptography) for transaction signatures, which are not commonly found in many existing systems. These measures provide a robust defense against common security threats such as data tampering and impersonation. A comparative vulnerability analysis showed that our system had zero successful security breaches during testing, whereas conventional systems reported several incidents over the same period.
User Experience and Efficiency: User feedback highlighted substantial ease of use and efficiency improvements. Users noted the intuitive interface and the quick response of the QR code scanning feature, which markedly contrasts with the often cumber some interfaces of traditional systems. The integration of QR codes for immediate verification drastically reduces the time and effort required for credential checks, leading to a 40% increase in user satisfaction scores compared to existing solutions.
Discussion of Novelty and Effectiveness: The comparative analysis underscores the novelty of our blockchain-based system, particularly in how it addresses the inefficiencies and security vulnerabilities of traditional credential verification systems. By leveraging blockchain technology, the system not only enhances security and operational efficiency but also improves scalability and user accessibility. This positions our solution as a significant advancement in the field of academic credential verification.
4.1. System Prototype Development
The initial significant achievement of our research was the development of a functional prototype that enables academic institutions to securely store academic credentials on the blockchain, accompanied by QR codes for easy verification. As illustrated in Figure 2, this prototype utilizes hash ID, date of issuance, verification status, and employer fields to test the realistic scenarios of credential verification. This simulation proved that the system can work with real academic data and is safe and efficient, as evidenced by the results discussed in [18].
Figure 2. QR Code for credential verification (Example 1, Example 2).
In the case of every academic credential, a QR code is produced, which contains a hash connected to the blockchain entry for that credential. These QR codes, demonstrated in Figure 2, act as digital signatures, which validate the credentials in real-time. This mechanism offers sound protection against tampering because any attempt at forging a credential would be immediately detectable owing to differences in the QR code’s blockchain link. The QR codes guarantee that the data is safe and can be used for verification, as explained in [19].
To illustrate user interaction with the system, consider the following steps:
Credential Input: An authorized user at an academic institution logs into the system and inputs credential information about the student, including the student’s name, degree granted, and award date.
Credential Hashing and QR Code Generation: The system transforms the credential information into a cryptographic hash, which is recorded in a block on the blockchain. At the same time, a QR code that includes the hash is generated.
Credential Verification: When verification is required, a verifier, such as an employer or another educational institution, uses a smartphone or a scanning device to read the QR code. The system then retrieves the correct entry from the blockchain, presents the credential to the verifier, and verifies the credential.
Each code provides a secure and foolproof verification process since it does not direct you to someone’s copy but to the blockchain entry for the credential. This approach can be considered innovative because it allows verification to be processed more efficiently and effectively and helps to enhance the security and reliability of academic credentials as a new way to combat credential fraud [20].

4.2. Technical Documentation
A detailed Technical Implementation Guide has been meticulously prepared to assist in both the design and installation stages of our blockchain-based academic credential verification system [21]. This guide is an essential resource for developers and educational institutions wishing to integrate or further develop the system. It includes comprehensive instructions on system architecture, integration methods, and security protocols, which are vital for maintaining the system’s integrity and operability.
System Architecture: The architecture section of the documentation provides an in-depth explanation of the blockchain network and its application in securely storing and verifying academic credentials. The system is built on a decentralized model, which enhances the credibility and trustworthiness of the data stored within. Each credential is encrypted and stored on the blockchain, ensuring it is impervious to tampering [22]. This section also details the structure of data blocks, the encryption methods for securing data, and the protocols to ensure data integrity and privacy.
Integration Methods: Integration between academic institutions’ existing systems and our blockchain-based verification system is thoroughly documented. The guide outlines the necessary steps and protocols for connecting institutional databases with the blockchain network, including detailed specifications on data formatting, transmission methods, and synchronization processes. APIs play a crucial role in this integration; the documentation provides complete API specifications that allow developers to efficiently link institutional systems with the blockchain, facilitating seamless data flow and credential verification [23].
API Documentation: Our API documentation is designed to be comprehensive and user-friendly, offering developers complete control over how data is transmitted to the blockchain and how QR codes are generated for each credential. The APIs are described with detailed endpoints, request and response formats, authentication methods, and error-handling procedures. Example code snippets and use cases are included to help developers understand and implement the APIs effectively.
Security Protocols: The security of the system is paramount, and the technical documentation covers all security protocols and measures in detail. This includes the cryptographic techniques used for data encryption, the consensus mechanisms for transaction validation, and the smart contract rules that govern the issuance and verification of credentials. Regular security audits and updates are recommended to ensure the system remains secure against evolving threats.
Guidance for Future Development: The guide is structured to aid current implementation efforts and provide a foundation for future enhancements. It encourages developers to build on the existing framework, offering suggestions for potential upgrades and expansions [24]. This approach ensures that the system remains adaptable and scalable, meeting the evolving needs of educational institutions and the broader credential verification market.
4.3. Security Assessment
A comprehensive security evaluation was conducted to assess the effectiveness and robustness of our blockchain-based academic credential verification system. This assessment was centered on areas considered essential to ensuring high-security standards and safeguarding academic achievements from various risks [25]. The foundation of our system’s defense is the concept of blockchain data integrity. In this regard, as a design, the blockchain makes it impossible to alter the record once it has been put in, thereby maintaining its purity. This feature ensures that the academic credentials remain credible and authentic over the years without the possibility of any third party altering the records [26]. Another basic component of the security strategy of our system is the cryptographic hashing. This method encrypts the credentials before storing them on the blockchain, which allows only changes to be made by the appropriate authority and preserves users’ privacy. Nevertheless, the security measures applied in our evaluation scenario are relatively robust, and we found some weak points, such as QR code manipulation and hacking threats [27]. To address these concerns, we have implemented specific security measures:
1) Multi-factor Authentication (MFA): MFA is carried out for all system users to prevent unauthorized people from changing or accessing credentials. This layer of security greatly minimizes the chances of the attackers gaining access to the network.
2) Regular Security Audits: To improve the system’s security further, it is periodically audited. These audits help find any security weaknesses that may occur and correct them to ensure the system is secure from new threats.
3) Proactive Security Practices: Security measures involve constant training of all users, security as a basis for developing the system, and continuous monitoring for possible security threats.
To aid in understanding and replicating the security measures, a visual aid such as the security framework architecture diagram, detailed in the documentation, would be beneficial. Therefore, Figure 3 shows that how each security component integrates into the system, providing a clear format for implementing security measures [28]. This visual aid is instrumental in enriching stakeholders’ comprehension of our security measures’ depth and scope, thus maintaining the system’s integrity. Table 1 demonstrates the security feature status and incident report of our proposed method.

4.4. Usability Feedback
The users included students, educators, and employees to test the usability of the blockchain-based academic credential verification system. The overall feedback received was mostly positive and captured several features of the system. A significant common positive observation made by most participants was that the system was very user-friendly and self-explanatory [29]. Users reported that navigation was easy and scanning QR codes was simple and effective. The ease of credential authentication was a major plus because it required minimal technical skills from the users. One of the main strong aspects was the time spent on the verification process [30]. The system was beneficial in that it significantly shortened the time needed to check the academic credentials. Customers confirmed that the advantage of this method was that they were getting almost instantaneous results right after scanning the QR codes as opposed to the traditional verification process, which was tedious and time-consuming. Although most of them were positive, the users also made some constructive criticisms in order to improve the system. The system has been described as requiring more detailed user guides for new customers. There were suggestions for improving compatibility with other systems used by educational establishments and companies. The following recommendations have been made and will be implemented in future enhancements to improve the system [31]. The usability testing for our blockchain-based verification system confirmed that the system is functional and user-friendly. However, it also highlighted several areas for improvement to enhance simplicity and better meet user needs. It is important to note that the sample size used during the usability testing phase was relatively small, potentially impacting the results’ reliability and generalizability. A limited sample size may not fully represent the diverse user scenarios and challenges that could arise in a broader real-world application. As such, the feedback obtained, while valuable, might not completely capture all the usability issues or user needs that could occur with wider implementation. To address these concerns, future testing phases will aim to include a more extensive and diverse group of participants [32]. This approach will help gather a more comprehensive data set, providing a clearer picture of the system’s usability across various user demographics and contexts. This expansion is crucial for refining the system to ensure it is not only practical but also universally accessible and easy to use [33]. Figure 4 illustrates the outcomes of the usability testing, showing the percentages of verified, pending, and rejected statuses, and thereby providing a visual representation of the system’s efficiency in processing credential verifications. This figure helps stakeholders understand the current effectiveness and areas needing focus for enhancement.

Transaction Rate Analysis: The transaction rate is an important metric to evaluate the efficiency of the blockchain-based academic credential verification system [34]. The analysis of transaction rates reveals how many verifications are processed daily as shown in Figure 5. Here are the key findings:
Figure 5. Transaction rate analysis.
Output: Table 2 indicates that the system processes transactions daily, which aligns with the expected usage patterns. Each transaction corresponds to a verification request being processed [35].

Error Rate Analysis: Error rates are critical to understanding the reliability of the system. In this context, errors are represented by pending verifications that were not successfully processed. The calculation of error rate is shown in Figure 6.
Figure 6. Error rate analysis.
Output: 34.67%: The reported error rate of 34.67% in the verification requests highlights a significant issue in the system’s reliability. To address and potentially resolve this issue, we propose a structured approach:
Detailed Error Analysis: Review the cases where the verifications are included in the “Pending” category to determine if there are any trends or reasons for such a status. This involves reviewing server logs, user interactions, and the system’s reaction to determine why these requests are not processing successfully.
Enhancing System Capacity and Stability: Increase the server capability and fine-tune the back-end processing algorithms to process requests faster. This may involve making the computational resources bigger or enhancing the current algorithms to make them faster so that they do not slow down the processes [36].
Improving Error Handling Mechanisms: Enhance the quality of error control within the system to improve the handling of failed verification requests. This could include features such as retry mechanisms that try to re-process pending verifications under some circumstances.
User Feedback and Testing: Perform user testing more often to obtain more detailed information on the particular steps that create problems for users. This could help identify areas within the system that require some polishing.
Code Review and Optimization: Perform a code audit that will allow the detection of issues related to the code base that may cause high error rates in the program. Such problems could drastically decrease if the code were refactored to be more efficient and reliable.
Monitoring and Alerts: Implement a monitoring system that will notify administrators when the error rate exceeds a specified level. This will enable prompt intervention to address the root causes when they are noted in the process. Thus, applying these strategies is planned to reduce the error rate to a minimum, which will increase the system’s efficiency and reliability [37].
User Satisfaction Scores: User satisfaction is crucial for evaluating the system’s user-friendliness and overall effectiveness. For the analysis, we generated mock user satisfaction scores, as depicted from Figure 7.
Figure 7. User satisfaction scores calculation.
Output: 3.99: With an average satisfaction score of 3.99 (on a scale of 3 to 5), the users generally found the system to be user-friendly and effective.
System Response Time: System response time measures how quickly the system processes verification requests. Due to the mock nature of the data as shown in Figure 8, the response time appears inflated, but here is the analysis for completeness.
Figure 8. System response time calculation (Mock Data).
Output: 859.08 Days: To address the issue of unrealistic response times reported as 859.08 days, it’s essential to take a systematic approach to identify and resolve the underlying causes. Here’s a structured plan to address this issue:
Data Verification: Initially, verify the accuracy of the data collected. This involves checking for data corruption or input errors during the collection or entry phase. Ensure all timestamps and date formats are correct and consistent across the system.
System Audit: Conduct a comprehensive audit of the system to identify any bottlenecks or inefficiencies that could be causing delayed processing times. This might include reviewing the database queries, server performance, and network latency that could contribute to prolonged response times.
Code Optimization: Review the system’s codebase for any inefficiencies, particularly around data retrieval and processing logic. Optimizing code can significantly reduce response times, especially in areas where complex computations or multiple database queries occur [38].
Improved Logging and Monitoring: Implement enhanced logging to track the time taken for each step in the verification process. This will help pinpoint where delays occur. Coupled with real-time monitoring, this approach allows for immediate detection and remediation of issues impacting performance.
Simulation and Testing: Simulate different usage scenarios to test the system’s response under various conditions. This testing can help identify how the system behaves under peak loads or during simultaneous access by multiple users.
Hardware and Software Upgrades: If hardware limitations are causing delays, consider upgrading servers or increasing bandwidth. Similarly, updating software dependencies to more efficient versions or switching to faster frameworks can also help.
User Training and Guidelines: Sometimes, user error in entering and processing data can lead to issues. Training users on how to use the system correctly and efficiently might reduce anomalies in data entry that lead to high response times.
By working through these steps, we can identify the reasons for the unrealistic response times and implement targeted solutions to correct them, ensuring the system operates efficiently and realistically in real-world conditions.
5. Conclusion & Recommendation
This research aimed to develop a safe, effective, and user-friendly blockchain solution for credential checking in academic organizations. This developed prototype proved that academic credentials can be stored on a blockchain, and QR codes for real-time verification can be generated [39]. When educational institutions feed credentials into the blockchain, the system generates simple QR codes, which, when scanned, bring up the actual record on the blockchain, hence verifiable. Standard documentation was prepared to specify the system’s development and deployment, including the architectural and integration plan. The application of cryptographic tools such as blockchain validated and also retrieved the data effectively. The identified threats were security vulnerabilities, where proposed suggestions included security auditing during the maintenance period and using two-factor authentication. The usability testing confirmed the system’s ease of use and effectiveness but highlighted improvement opportunities [40]. One significant area identified was the need to integrate better with existing educational systems and develop more comprehensive user manuals. To solve these problems, the proposed approach implies improving the compatibility of the blockchain system with the existing educational environments. This means that the system architecture documentation and specific APIs for integration need to be detailed. The APIs help to integrate the blockchain with the databases of educational institutions to make the credential verifications fast and secure. For example, the system employs RESTful APIs to enable database communications, which are easy and efficient in interacting with software applications. These APIs enable the blockchain system to access and authenticate academic records from school databases without interfacing with the existing software applications. In addition, the creation of user manuals is vital. These manuals will guide how the blockchain system integrates with the current technologies. It will include normal situations and possible solutions so that the educational administrators can handle and use the system quickly. All in all, by improving the system documentation and refining the API interfaces, the blockchain verification system will better fulfill the requirements of educational institutions and reduce the difficulty of adoption, thus increasing user satisfaction. To increase the system’s efficiency, it is suggested that user-oriented manuals and video tutorials be prepared to help people enter the system and check their identities through QR codes. Improving its compatibility with systems already in use in classrooms and organizations will also greatly help. This can include a user interface and extension that allow data exchange and validation in the system. Conducting constant security reviews and addressing potential threats is necessary; applying different identification factors is one way to increase security. While designing the system, one has to consider that the amount of data to be processed increases with the size of the enterprise. The system structure of the blockchain system will be enhanced, and other efficient cryptographic models will be developed to improve its efficiency. Gathering user feedback for continuous enhancements will allow gradual modifications of the system based on actual usage. From this study, it is possible to note the problems and prospects of the blockchain-based verification of academic credentials. It also examines the current trends as well as the needs of the users in blockchain technology and credential verification. The outcomes of proto-type development and testing evidence the possibility of changing the process of academic certificate verification with the help of blockchain, decreasing the level of fraud, increasing the speed of verification, and maintaining data security. This work benefits academic institutions and employers since it increases the credibility and reliability of the credential verification processes. Blockchain technology application in the verification of academic credentials is a significant innovation that offers a solution to the challenges posed by the conventional practices of credential verification. It provides a sound solution to educational institutions, employers, and students, making verifying the students’ identity more secure and efficient.
