  In this paper, we propose a certificate sharing system based on blockchain
that gives students authority and control over their academic certificates. Our
strategy involves developing blockchain-based NFT certifications that can be
shared with institutions or employers using blockchain addresses. Students may
access the data created by each individual institute in a single platform,
filter the view of the relevant courses according to their requirements, and
mint their certificate metadata as NFTs. This method provides accountability of
access, comprehensive records that are permanently maintained in IPFS, and
verifiable provenance for creating, distributing, and accessing certificates.
It also makes it possible to share certificates more safely and efficiently. By
incorporating trust factors through data provenance, our system provides a
countermeasure against issues such as fake and duplicate certificates. It
addresses the challenge of the traditional certificate verification processes,
which are lengthy manual process. With this system, students can manage and
validate their academic credentials from multiple institutions in one location
while ensuring authenticity and confidentiality using digital signatures and
hashing for data protection against unauthorized access. Overall, our suggested
system ensures data safety, accountability, and confidentiality while offering
a novel approach to certificate distribution.
