[METADATA] Horizons

[SOLUTION] Please describe your proposed solution

Nearly a million Ethiopian students take national exams each year, yet the current educational ecosystem lacks accessible online mock exams to help prepare students adequately. With a passing rate of only 3%, it’s clear that the existing methods of exam preparation are insufficient. This lack of resources not only hampers students' digital readiness but also contributes to low success rates in national examinations. Our solution aims to address these critical gaps by providing a robust platform for exam preparation.

Approach Rationale

We propose to build a web and mobile platform leveraging the Cardano blockchain, which will enable students to take online mock exams. The choice of the Cardano blockchain is intentional; its decentralized nature ensures data security, transparency, and immutability, thereby fostering trust among users. Our approach incorporates blockchain technology for several reasons:

• Data Security: Students’ records and exam results will be stored securely, reducing the risks of tampering and unauthorized access.
• Transparency: The immutable ledger of the blockchain provides transparency in the evaluation process, allowing students, educators, and administrators to trust the validity of the results.
• Decentralized Identity Management: Utilizing Cardano’s decentralized identity protocols allows students to control their identities securely, enhancing privacy and preventing unauthorized access.

Project Engagement

Our project will engage a diverse set of users, including:

• Students: Providing them with access to online mock exams, enhancing their preparedness for national exams.
• Educators: Offering tools to track student progress, provide feedback, and enhance their teaching methods through data-driven insights.
• Administrators: Enabling them to manage student records and examine performance metrics efficiently, thus streamlining the educational management process.
• External Stakeholders: Such as employers and academic institutions, who will benefit from a more efficient verification process for academic credentials.

Impact Demonstration

We will demonstrate the impact of our solution through various metrics:

• Increased Pass Rates: By providing access to online mock exams, we expect to see a significant increase in national exam pass rates among students using our platform.
• User Engagement Metrics: Tracking the number of registered users, the frequency of exam attempts, and user feedback will provide insights into the platform’s effectiveness and user satisfaction.
• Qualitative Feedback: Collecting direct feedback from students and educators to continuously improve the platform based on real user experiences.

Key Features and Technology Stack

1. Decentralized Identity Management (DID)

• Problem: Traditional systems for managing student and staff identities are prone to identity theft, data breaches, and unauthorized access.
• Solution: E-Test provides decentralized identity management using Cardano-based DID protocols. Each user (student, teacher, or administrator) is issued a decentralized, cryptographic identity. This ensures privacy and prevents unauthorized access while enabling secure, trustless interactions.

1. Blockchain-based Credential Issuance and Verification

• Problem: Paper-based or centralized digital certificates are vulnerable to fraud and tampering.
• Solution: E-Test issues tamper-proof digital certificates on the blockchain, generating immutable records of achievement. Third parties can verify these certificates quickly and easily without needing to contact the issuing institution.

1. Secure Payment System with ADA Integration

• Problem: Tuition payments often face issues such as slow processing times and high transaction fees.
• Solution: E-Test integrates a secure payment system allowing students to pay for courses using ADA, Cardano’s native cryptocurrency, ensuring fast and low-cost transactions.

1. Tamper-proof Certificate System (UTCert Integration)

• Problem: Traditional certificates are often paper-based and prone to tampering or loss.
• Solution: E-Test integrates with UTCert, ensuring every certificate issued is securely stored on the blockchain for real-time verification of authenticity.

1. Reporting and Analytics

• Problem: Educational institutions need robust tools to measure performance and improve their services.
• Solution: E-Test provides detailed reporting and analytics tools for institutions to track student performance, course effectiveness, and user engagement.

Technology Stack

• Blockchain: Cardano, for decentralized data storage, smart contracts, and secure transactions.
• Smart Contracts: For automating processes such as issuing certificates and updating student records.
• Decentralized Identity (DID): To provide secure, cryptographic identities for all users.
• Frontend:
• Web: Developed using the MERN stack (MongoDB, Express.js, React.js, Node.js) for a robust and dynamic web application.
• Mobile: Built with Flutter, ensuring a seamless and intuitive experience for students, teachers, and administrators on mobile devices.
• Backend: A robust backend infrastructure that integrates with Cardano blockchain nodes for secure data handling.

Conclusion

The E-Test solution leverages the unique capabilities of blockchain to offer a transparent, secure, and efficient platform for managing educational records, issuing credentials, and tracking student progress. By decentralizing data management, automating certificate issuance, and integrating smart payment options, E-Test will address key challenges in the educational ecosystem, reduce inefficiencies, and provide a higher level of trust, transparency, and security for all stakeholders involved.
