A DECENTRALIZED FRAMEWORK FOR ACADEMIC CERTIFICATE ISSUANCE, VERIFICATION, AND REVOCATION USING ETHEREUM SMART CONTRACTS AND IPFS: DESIGN, IMPLEMENTATION, AND EVALUATION ON THE SEPOLIA TESTNET

Uche Kinglsey *Ike, Chamberlyn Ononiwu, Lilian Ijeoma Durunna, Collins Obialor · 5 authors

Academic certificate fraud is a persistent problem across developing economies, undermining trust between graduates, employers, and higher education institutions. In Nigeria, this has prompted a federal mandate requiring every employer to verify staff credentials; yet existing verification processes remain manual, slow, and easily circumvented. This paper proposed, implemented, and evaluated a fully decentralized academic certificate management framework built on the Ethereum blockchain, leveraging Solidity smart contracts, the InterPlanetary File System (IPFS) for off-chain document storage, QR-code-enabled instant verification, and on-chain revocation.The system was deployed and tested on the Ethereum Sepolia testnet using Hardhat 2.19.4 and ethers.js 6.x. Results show that issuing a single certificate costs a fraction of a cent, that batch issuance lowers this cost further, that verification is free for employers, and that the system correctly detects fabricated or altered certificates in the overwhelming majority of cases while cutting verification time from days to seconds. These findings demonstrate that blockchain-based credential management is technically sound, affordable, and readily deployable in resource-constrained institutional settings, offering a practical path toward restoring trust in academic credentials across Nigerian and other African universities.

A Privacy-Preserving Federated Learning Framework for Collaborative Academic Certificate Fraud Detection Across Institutions

Miriam W. Kaara, Jael S. Wekesa, Michael W. Kimwele

The integrity and credibility of educational institutions worldwide are being undermined by the growing issue of academic certificate fraud. The public's trust in the educational system, the integrity of job opportunities, and the legitimacy of authentic credentials are all negatively impacted by academic dishonesty. The majority of academic credentialing systems, both centralized and blockchain-based, focus on academic credential validation and immutability, even though academic institutions have embraced technology to improve academic credentialing procedures. This suggests that their support for intelligent and private fraud detection is minimal. In this work, we suggest an integrated method that combines smart anomaly detection with Federated Learning (FL). This makes it possible for several organizations to build a model for detecting certificate fraud without disclosing private information to other organizations. Each institution's private information is retained and incorporated into a global model. This enables the framework to handle concerns about data ownership and privacy as well as regulatory compliance. The framework uses Extreme Gradient Boosting (XGBoost) to identify anomalies in metadata and Convolutional Neural Networks (CNNs) to detect visual forgeries in certificates. A decentralized node is used to train the models, which are merged using the Federated Averaging (FedAvg) algorithm. The federated model performs well in anomaly detection, according to the experiments conducted. When compared to conventional centralized approaches, it significantly reduces false positives and false negatives, with an accuracy of up to 94% and an AUC of 0.97. The model's findings imply that a federated learning approach would make it possible for institutions to detect fraud in a secure, scalable, and cooperative manner. In this regard, this framework offers a workable way to create digital credential systems that are more trustworthy and protect privacy. Key words: Federated Learning, Blockchain, certificate fraud detection, privacy preservation, distributed datasets, secure collaboration.

Blockchain Technology for Academic Credential Verification Preventing Transcript Fraud in the USA

Sathy Akter*

Currently, the most significant threat to the validity of academic credentials in the United States is the advanced forgery of transcripts along with diploma mills. This research study addresses the potential of blockchain technology as a decentralized means to protect academic credentials. By integrating recent academic research and technical frameworks, this study analyzes the shift from centralized databases to immutable, distributed ledgers. The integration of various perspectives, including advanced zero-knowledge proof architectures as well as legal frameworks for transnational data circulation, is a major innovation of this study. Using a systematic literature review and a case study approach, the research indicates that though blockchain's potential to enhance security and automate processes through smart contracts is indeed great, a number of legal, compliance, and technical barriers have to be removed for it to be a viable option. This study proposes that the combination of artificial intelligence (AI), along with blockchain technology, provides the most secure option for U.S. higher education institutions.

Responsible Generative AI Use in Thesis Work: The ALIGN Framework and Checklist for Students and Supervisors

Florian Buehler

Generative artificial intelligence is increasingly built into how students prepare, write, and revise bachelor's and master's theses, yet the principles meant to govern responsible use were largely written for research outputs rather than for supervised, assessed, and educational student work. This study asks what responsible AI use requires in the thesis specifically, and develops a framework for it. Guidance on responsible AI use already exists for research - including the eight-principle consolidation of Knöchel et al. (2025): regulations, data security, quality control, originality, bias mitigation, accountability, transparency, and broader impact - but they were written for published outputs, not supervised and assessed student work. Using these established principles as one structured starting point rather than a template to apply, I conducted 28 semi-structured interviews with current students, recent graduates, lecturers and supervisors, program managers, and domain experts, analyzed with Template Analysis, and let the evidence confirm, reshape, and extend them. Quality control and accountability became load-bearing; originality, transparency, and broader impact required substantial reinterpretation; data security and bias mitigation remained normatively important despite limited spontaneous salience. The evidence further pointed to a stake the research framework does not contain: the integrity of the learning the thesis is designed to develop and certify. I define this ninth principle, learning integrity, as alignment between intended thesis learning outcomes, the activities meaningfully performed by the student, and the evidence used to assess them. The resulting ALIGN framework combines nine principles with prospective agreement, process-based supervision, proportionate disclosure, verification, and dialogic defense - a triangulated integrity architecture for use before, during, and at the end of thesis work, rather than any single instrument treated as proof of authorship. The paper closes with a one-page student checklist and a citable disclosure sentence for thesis methods sections. The study contributes to education research and higher education assessment by specifying how generative AI changes the relation between student agency, self-regulated learning, evidence of competence, and academic integrity in capstone thesis work.

Enhancing Hostel Grievance Management Through Permissioned Blockchain: A Step Toward Transparent and Accountable Campus Living

Parikshit Daivadnya, Pratibha D. Patil, Sakshi Kulkarni, Dhawal Chhindam · 5 authors

Hostels are an essential part of campus life in technical institutions, directly influencing student welfare, safety, and satisfaction. However, traditional hostel grievance management systems often face issues of delayed responses, lack of transparency, and potential data manipulation, resulting in a trust gap between students and administrators. This paper reviews how permissioned blockchain technology can transform hostel grievance systems by ensuring transparency, accountability, and tamper-proof recordkeeping. A hybrid blockchain architecture integrating institutional databases with a distributed ledger is examined for its ability to maintain verifiable complaint histories while protecting privacy. The study highlights the potential educational and administrative benefits of adopting such systems, including faster grievance resolution, fair decision-making, and improved trust within hostel communities. Recommendations are provided for technical institutions aiming to modernize hostel management through blockchain-based digital governance.

Blockchain-Based Academic Certificate Verification System: A Secure Web Application for Certificate Authentication Using Java, Spring Boot, Ethereum, MetaMask

Prof. Narde S. A., Yadav N.S., Ghodake D.T., Patil S.J., Salunkhe S. S.

Abstract In recent years, the rapid growth of digital technologies in education has increased the importance of academic certificates for employment, higher studies, and professional validation. However, the issue of fake and forged certificates has become a serious challenge for institutions and organizations. Traditional certificate verification systems are manual, time-consuming, and often lack transparency and security. These systems are also vulnerable to data manipulation and unauthorized access due to centralized storage. To address these challenges, this paper proposes a blockchain-based academic certificate validation system. The system uses blockchain technology to securely store certificate data in the form of cryptographic hash values generated using the SHA-256 algorithm. Since blockchain is decentralized and immutable, once data is stored, it cannot be altered or deleted. The system allows administrators to upload student data and issue results, which are then stored on the blockchain. Each certificate is associated with a unique verification ID and can be validated using QR codes or direct input. The proposed system improves efficiency, enhances data security, and reduces the risk of fraud. The results demonstrate that the system is faster, more reliable, and more secure than traditional methods.

Blockchain-Based Diploma Authentication System: A Design Science Approach Using Smart Contracts and Ganache

Haryati Haryati, Dwi Vernanda

Academic credential fraud poses a critical challenge to Indonesian higher education, with approximately 30% of job applicants providing false academic qualifications while conventional verification processes require 2–4 weeks with significant administrative costs. This research addresses the gap where 77% of blockchain education research remains conceptual by proposing and evaluating a four-layer blockchain system architecture for academic diploma authentication. Using Design Science Research Methodology (DSRM), the study designs and implements a layered architecture comprising a Presentation Layer (React 18.2.0 with client-side SHA-256 hashing), Application Layer (Node.js 18.20.8 with Web3.js), Data Layer (PostgreSQL 14.5 for off-chain metadata), and Blockchain Layer (DiplomaValidator smart contract in Solidity 0.8.19 on Ganache 2.7.1). The architectural design enforces separation of concerns, enabling tamper-evident credential storage through immutable on-chain hash registration and trustless public verification through zero-gas view functions. Comprehensive evaluation through 38 functional tests, performance benchmarking, security auditing, and integration testing demonstrates 100% pass rate across all categories. Performance metrics show registration in 15.23 ms (240,082 gas units) and verification in 9.47 ms at zero gas cost, achieving 51.81 TPS throughput. Security audit yields 95/100 with zero high or medium vulnerabilities. The primary contribution of this research is a formally documented four-layer blockchain architecture for academic credential authentication validated through DSRM providing a replicable architectural model and quantified performance baselines for the Computer Science community and Indonesian higher education institutions considering blockchain adoption

ParikkhaChain: Blockchain-Based Result Processing and Privacy-Preserving Academic Record Management for the Complete Examination Lifecycle

Rabib Jahin Ibn Momin, Ahmed Mahir Sultan Rumi, Rezwana Reaz

Academic examination systems worldwide continue to rely on centralised, opaque record-keeping that is often vulnerable to credential forgery, result tampering, examiner bias, and the absence of transparent re-evaluation pathways. Existing blockchain-based approaches in education focus predominantly on post-hoc certificate storage or online-only examination portals, leaving the complete onsite examination lifecycle, from conducting exams through scrutiny, largely unaddressed. This paper proposes ParikkhaChain, a blockchain-based framework that covers the entire examination lifecycle of an onsite examination system with three distinguishing contributions: (i) anonymous script evaluation through cryptographic hashing of answer scripts before examiner access, thereby eliminating identity-based bias; (ii) a transparent evaluation and scrutiny workflow backed by an immutable on-chain audit trail that records every mark submission and grade revision; and (iii) inclusion of privacy-preserving verification using zero-knowledge proofs and off-chain storage mechanisms. The system is architected around four Solidity smart contracts deployed on the Ethereum blockchain. The proposed architecture is the first initiative to our knowledge to support physical examination process, anonymous marking, and re-evaluation transparency. We successfully simulate full exam cycles of an onsite exam to grade-sheet generation using a working prototype on a large scale of 100 courses and hundreds of teachers and students. The experimental results show that the system can manage online examinations of hundreds of courses, students and faculties efficiently with great throughput, low storage, and transaction cost.

Federated Blockchain for Secure AI-Proctored Examination Systems: Architecture, Implementation, and Evaluation

Rito Tensy, Meera Rose Mathew

Remote examination platforms have experienced exponential growth, yet centralized architectures remain susceptible to data manipulation, unauthorized record alteration, and deficient audit mechanisms. This work introduces a federated, permissioned blockchain framework built upon Hyperledger Fabric, integrated within an AI-driven online examination platform designated as Evalon. The proposed architecture distributes ledger maintenance across multiple authorized institutional peers, recording cryptographic digests of examination lifecycle events—including candidate authentication, session boundaries, proctoring anomalies, and grade finalization—without exposing personally identifiable information on-chain. A Byzantine fault-tolerant ordering service coupled with endorsement policies ensures that no single administrative entity can unilaterally modify committed records. The blockchain substrate operates alongside a microservices backend deployed on serverless cloud infrastructure, facilitating real-time event validation through RESTful APIs and deterministic smart contracts. Complementing the integrity layer, computer vision models perform continuous behavioral analysis, detecting multi-face presence, gaze deviation, and anomalous motion patterns during live sessions. Experimental evaluation across 12,000 simulated examination sessions demonstrates a 99.7% hash verification success rate, sub-second ledger commit latency under concurrent loads of 500 transactions per second, and a 34% reduction in undetected integrity violations compared with conventional centralized logging. The combined framework establishes a tamper-resistant, auditable, and scalable ecosystem suitable for academic, certification, and enterprise assessment deployments.

Unified Blockchain and Machine Learning Framework for Secure Digital Certification and Adaptive Course Recommendations

Renangi Sandeep, Thupakula Leena Sri, K Ananda Rutvik Reddy, Nimmakayala Kethana · 6 authors

This growth of digital learning platforms has presented a twin need: to deliver a learner a highly personalized educational journey and to deliver academic credentials that are verifiable, safe, and unchangeable. The current systems tend to address these goals separately and as a result, there are disjointed ecosystems with complex recommendation engines without trusted credentialing systems and sound certification systems that do not provide any course selection guidance. To fill this gap, this paper presents the Integrated Adaptive Learning and Certification Framework (IALCF), a new architecture that integrates into a LightGBM-based recommendation system a blockchain-based digital certification protocol in a synergistic manner. The recommendation module is an active learner profile analyzer that uses past performance, real-time interaction metrics and dynamically recommenders, predicting course selection with an accuracy of 98.7 and mean absolute error (MAE) of 1.18. The certification module is based on a more advanced X.509 standard with a delegated Proof-of-Stake (dPoS) blockchain, which forms a tamper-evident credential storage and an efficient verification algorithm, which has a verification success rate of over 95 percent in high-load conditions. The experimental findings reveal that the IALCF is a scalable, efficient and safe end-to-end solution to contemporary e-learning settings and is effective in integrating personalized learning with credible management of credentials.

A DECENTRALIZED CERTIFICATE VERIFICATION SYSTEM LEVERAGING BLOCKCHAIN AND NON-FUNGIBLE TOKENS

Tivlumun Ge, Joel Aondofa Udoji, Isaac Adom

Academic certificate verification in many institutions is still carried out using centralized and manual systems, which are prone to forgery, data manipulation, high administrative costs, and delays in verification. These challenges reduce the reliability and efficiency of credential validation. This research work focuses on the development of a Decentralized Certificate Verification System (DCVS) that improves security, transparency, and trust in academic credential verification. The proposed system uses blockchain technology to represent academic certificates as Non-Fungible Tokens (NFTs) based on the ERC-721 standard deployed on the Polygon blockchain. Certificate documents and metadata are stored off-chain using the Interplanetary File System (IPFS), while cryptographic references are recorded on the blockchain to ensure data integrity and prevent tampering. The system adopts Self-Sovereign Identity (SSI) principles, allowing students to own and share their credentials while enabling employers and institutions to verify certificates without relying on a central authority. Evaluation of the system on the Polygon test network showed a reliable result with a minting confirmation time of 3.2 seconds, less than the 10-second standard benchmark, verification latency of 0.8 seconds, less than the 2-second benchmark, and a transaction cost of 0.00021 MATIC, less than the 0.01 MATIC standard cost. The study demonstrates that blockchain-based solutions can effectively address the challenges of traditional academic certificate verification systems.

AI Based Decentralized Academic Credential Verifica-tion System Using Blockchain

P. Gayathri Reddy

The increasing incidents of forged academic certificates and the inefficiencies of traditional verification systems highlight the urgent need for a secure, transparent, and reliable credential management mechanism. Conventional systems are largely centralised, time-consuming, and prone to manipulation, resulting in high administrative overhead and verification delays. We prepared an AI-Based Decentralized Academic Credential Verification System that leverages blockchain technology, smart contracts, and artificial intelligence to provide a tamper-proof platform for issuing, storing, and validating academic records. Artificial Intelligence is integrated to perform anomaly detection during certificate issuance and AI-based facial authentication for students, enhancing security and preventing fraudulent entries before blockchain storage. Students gain permanent, secure access to their verified credentials, while verifiers, such as employers, can instantly authenticate certificates using blockchain records or QR code scanning, eliminating the need for intermediaries. By integrating Ethereum, Solidity, Web3.js, IPFS, React.js, and AI models, the proposed system delivers a decentralized, scalable, and cost-effective solution that enhances trust, reduces verification time, and effectively combats academic credential fraud.

DentaChain: A Provenance-Verified Smart Contract System for Dental Billing Fraud Prevention

Mujahid Ullah Khan Afridi

Dental billing fraud costs the United States an estimated $5.2 billion to $17.4 billion annually, yet detection relies entirely on retrospective rule-based auditing that leaves the real-time claimsubmission window unaddressed. The laboratory-to-clinic workflow governing prosthetic manufacturing remains paper-based, dispute-prone, and disconnected from insurance adjudication. This paper presents DentaChain, a permissioned blockchain framework chaining dental laboratory workflow management directly to insurance claim verification. Three Solidity smart contracts deployed on Hyperledger Besu automate milestone-driven prosthetic manufacturing with escrowbased payment release, enforce a causal provenance chain that structurally eliminates phantom billing prior to any machine learning inference, and maintain an immutable, regulator-accessible compliance ledger. A dual-model machine learning pipeline completes the system: a Random Forest classifier with synthetic minority oversampling predicts prosthetic defect risk before manufacturing begins (AUC = 0.991, recall = 0.949), while a Random Forest and Isolation Forest ensemble detects claims across four fraud typologies in real time (AUC = 0.986, recall = 0.927), evaluated under partial-signal fraud injection for conservative performance estimates. At the recommended operating threshold, 95.5% of claims are auto-approved, reducing adjudicator workload. A synthetic dataset of 50,000 Current Dental Terminology (CDT) claims and 12,000 laboratory orders is released publicly to support reproducibility.

From Concept to Practice: A Blockchain‐Based Solution for Secure and Efficient Academic Credentials in Higher Education

Avni Rustemi, Fisnik Dalipi

ABSTRACT The generation and verification of academic credentials, particularly diplomas, is crucial for the secure functioning, enhanced legitimacy and confidentiality of higher education institutions (HEIs). Digitising the internal services of HEIs is of great importance, as it mitigates the potential abuse of diplomas and other important documents. The prevalence of forgery attempts highlights the need for robust verification methods. In this regard, blockchain technology can be considered as a solution due to its capability to ensure the immutability, decentralisation, security and transparency of all documents stored on the blockchain network or storage. In this paper, we aim to move from concept to practical implementation of a blockchain‐based framework for generating and verifying diplomas, named Diploma Integrity Authentication Record (DIAR), which, in addition to the digitalisation of diplomas and academic documents, also enables their fast, secure, and cost‐effective verification. Through the paper, we describe in detail the process of practical implementation of the DIAR framework, presenting the smart contract for generating and verifying diplomas, the process of encrypting and storing diplomas as non‐fungible tokens on the blockchain network or storage. At the same time, the challenges of practical implementation are also described, which are predominantly related to the scarcity of blockchain solutions for generating and verifying diplomas in HEIs. Significant attention and emphasis are placed on the legal matters pertaining to the implementation and safeguarding of students' identification and data privacy.

An anti-corruption system for academic achievement verification in kazakhstani higher education using blockchain and artificial intelligence

Abdul Razaque, Saule Amanzholova, Galimkair Mutanov, Olga Ussatova · 8 authors

This article focuses on developing an anti-corruption system for certifying students’ academic achievements in Kazakhstani higher education institutions by utilizing blockchain and artificial intelligence AI technologies. We specifically propose the Academic Integrity Verification System (AIVS), a revolutionary system that combines blockchain’s tamper-proof storage with AI’s anomaly detection capabilities. The system reduces major risks in traditional academic record management while ensuring transparency, precision, and proactive fraud detection. The simulation was conducted at the International Information Technology University (IITU) using Ethereum-based blockchain and AI models. In simulated testnet experiments, AIVS achieved an 85% reduction in verification time compared to traditional processes and delivered a 95% overall model accuracy in record validation. These results demonstrate the potential of blockchain and AI integration for improving efficiency and integrity in academic verification workflows. These findings demonstrate that our proposed AIVS enhances academic transparency, reduces corruption, and provides a scalable framework for secure academic record management. The proposed strategy marks a significant step forward in the governance of digital education in Kazakhstan and abroad.

VeritasChain: A Decentralized Blockchain for Academic and Research Integrity

Sayeda Tahmina, Md. Al-Amin Bhuiyan

Academic credential fraud and falsification of research outputs remain persistent challenges in higher education and research communities. Traditional centralized credential verification systems are vulnerable to tampering, slow verification processes, and lack of transparency. This research introduces a robust blockchain-based consortium framework for transparent and tamper-proof verification of academic credentials and research outputs. Unlike prior works that primarily address identity or degree validation, our system integrates universities, accreditation authorities, and publishers into a multi-layered consortium blockchain, ensuring trust among multiple stakeholders. To preserve privacy, zero-knowledge proofs (ZKPs) are applied, enabling credential verification without disclosing sensitive personal data. The framework also introduces a dynamic revocation mechanism to handle fraudulent, plagiarized, or revoked certificates and publications. A prototype implementation on Hyperledger Fabric demonstrates feasibility, achieving high throughput (182 TPS), low latency (1.2 s average block confirmation), and efficient scalability with multiple nodes. Our results highlight the potential of blockchain in building a global, tamper-proof, privacy-preserving academic verification ecosystem, addressing credential fraud and ensuring research integrity.

Privacy-Preserving Academic Transcript Verification Using Zero-Knowledge Proof

Ryo Watanabe, Wutichai Chongchitmate, Nagul Cooharojananone

In admissions and hiring, transcript verification often requires only a threshold decision, for example a grade point average of 3.0 or higher or a Python grade of B or better. However, prevailing workflows demand full transcript disclosure, creating privacy risks and evaluation bias. We present a deployable system that proves a chosen subject meets a required threshold without revealing the score or any other subjects. The system integrates Groth16 Succinct Noninteractive Arguments of Knowledge (SNARKs) with W3C Decentralized Identifiers (DID) and Verifiable Credentials (VC) in a four-service architecture for DID registration, university issuance, student proving, and third-party verification. Holder identity is enforced offcircuit via a DID based challenge-response protocol where the student signs the verifier's nonce and the verifier checks that the signer's DID matches the VC's subject identifier. The zero-knowledge (ZK) circuit proves only Merkle inclusion and threshold comparison. The university signs the transcript's Merkle root with an Ed25519 signature. The verifier validates this signature using a key obtained from the university domain or a trusted registry, never from the student. On standard development hardware, steady-state proving latency is between 0.66 and 1.10 seconds. The verifier learns only a pass/fail bit, enforcing data minimization. In our negative test suite, no false accepts were observed.

An Analysis of the Mechanism and Mode Evolution for Blockchain-Empowered Research Credit Supervision Based on Prospect Theory: A Case from China

Gang Li, Zhihuang Zhao, Ruirui Chai, Mengjiao Zhu

The crisis of research integrity triggered by academic misconduct, such as scientific fraud and paper retractions, has emerged as a critical issue demanding urgent resolution within the academic community. Blockchain (BC), with its core features of distributed ledger, peer-to-peer transmission, consensus mechanisms, timestamps, and smart contracts, offers novel technical solutions for research institutions seeking efficient models of research credit supervision. By incorporating the psychological factors of risk perception among decision-makers and the dynamic evolution of behavioral decision-making, and drawing on prospect theory, this study has constructed an evolutionary game model involving researchers, scientific research institutions, and governmental entities to examine BC-enabled research credit supervision. This model analyzes the key determinants influencing scientific research institutions’ adoption of blockchain regulation (BC regulation), elucidates the behavioral characteristics and boundary conditions of research integrity among researchers under this new regulatory paradigm, and reveals the dynamic evolutionary trajectory of collaborative supervision between governments and scientific research institutions. The findings indicate the following: (1) Compared to traditional regulation, the BC regulation demonstrates superior regulatory effectiveness at equivalent levels of researcher integrity and misconduct costs, as well as under identical settings for reputational loss and penalties. (2) In addition to cost considerations and government subsidies, factors such as loss aversion coefficient, risk preference coefficient, and privacy breach losses are critical in influencing research institutions’ decisions to implement BC regulation. (3) The evolution of blockchain-empowered regulatory models encompasses three distinct evolutionary patterns. This study provides a theoretical foundation and a simulation case to optimize regulatory strategy formulation and resource allocation, thereby enhancing the effectiveness of research credit supervision.

Blockchain-Enabled Academic Assessment for Secure, Scalable, and Tokenized Evaluation on Ethereum and Polygon

Poornima G. Naik, Rajani S. Kamath, S. S. Jamsandekar

Blockchain technology has gained prominence in academia as a promising solution to strengthen security, transparency, and interoperability in academic assessment systems. The current research presents the design and implementation of a decentralized Ethereum based examination framework using Ethereum smart contracts, role-based access control (RBAC), and ERC20-based fungible tokenization for academic credits. In contrast to prior works which focus primarily on conceptual frameworks, the proposed system is deployed and evaluated on the Ethereum and Polygon (Layer2) test networks. Further, the architecture integrates off-chain storage via IPFS to minimize gas consumption, while role-specific smart contracts ensure data privacy and regulatory compliance. To enhance trust and confidentiality, zero-knowledge proofs (ZKPs) are incorporated for privacy-preserving answer verification, and decentralized identity (DID) standards are applied for student authentication. Experimental results demonstrate that Layer-2 deployment reduces transaction costs by up to 65% compared with Ethereum mainnet, and the system achieves stable throughput of 42 transactions per second (TPS) under simulated student workloads. Security validation using Slither and MythX confirms resistance to re-entrancy, double-spending, and unauthorized access attacks. The proposed framework establishes a quantifiable, fraud-resistant, and efficient academic assessment model, paving the way for scalable blockchain adoption in higher education.

A Secure Framework for Academic Certificate Authentication on Ethereum Blockchain

Sourav Narvekar, Sanket Patil, Prastuti Motghare, Tejashreeraje Panaskar · 5 authors

Academic certificate verification is plagued by on-going issues of fraud, manipulation, and inefficiency in the digital age, which erodes credibility and trust among people and organizations. Using the Ethereum blockchain's fundamental features of immutability, decentralization, and fraud prevention, this study explores how to safely issue and validate academic cre-dentials. By connecting certificates to tamper-proof cryptographic hashes stored on the blockchain, the suggested system uses smart contracts to automate certificate issuance and validation. The framework greatly reduces credential falsification and simplifies verification for employers and educational institutions by doing away with reliance on centralized authorities and offering transparent, auditable records that are available to authorized stakeholders.
