BLOCKCHAIN AS A TOOL FOR CERTIFICATE AUTHENTICATION

Abstract

 With the rise in counterfeit certificates, the credibility of academic credentials has been undermined, posing 
significant challenges for educational institutions and employers alike. Traditional methods of certificate verification 
are often inefficient and prone to error. To address these concerns, this paper proposes a blockchain-based digital 
certificate system that ensures both authenticity and transparency in the verification process. Leveraging blockchain’s 
immutable and transparent properties, the proposed system allows educational institutions to generate and securely store 
certificates in a tamper-proof digital format. By creating a unique hash value for each certificate, it ensures that any 
alteration is easily detectable. Additionally, a QR code is embedded on each paper certificate, allowing users to verify 
its authenticity via mobile or web applications. This research highlights the essential security features needed for 
blockchain-based document verification and examines current shortcomings in existing systems. The proposed solution 
offers a more reliable and efficient method for verifying academic credentials, safeguarding the integrity of educational 
certifications.
