        abstract = {The increasing use of digital documents in academic and professional domains has created a strong need for reliable and secure verification systems. Traditional methods of certificate verification are often manual, time-consuming, and prone to forgery and manipulation, leading to trust issues among institutions and employers. To address these challenges, this paper proposes a Blockchain-Based Skill Wallet and Certificate Verification System that ensures secure, transparent, and tamper-proof validation of credentials.
The system integrates Optical Character Recognition (OCR) for initial document validation and utilizes blockchain technology to store verified records in an immutable and decentralized manner. Each transaction is securely recorded with cryptographic hashing, ensuring data integrity and traceability. Additionally, a Skill Wallet feature enables users to manage and share verified certificates digitally through QR code-based authentication, allowing instant verification by employers.
The proposed system enhances trust, reduces verification time, and provides a scalable solution for secure credential management across multiple stakeholders, while incorporating OCR-based document validation, institute-level verification, blockchain-secured storage with hashing, and QR code-enabled authentication for instant and reliable credential verification by employers.},
