  Blockchain has proven to be an emerging technology in the digital world,
changing the way everyone thinks about data security and bringing efficiency to
several industries. It has already been applied to a wide range of
applications, from financial services and supply chain management to voting
systems and identity verification. An organization must verify its candidates
before selecting them. Choosing an unqualified candidate can ruin an
organization's reputation. In this digital era, many key fraudulent schemes are
rampant in many companies and one of them is certificate fraud. It is possible
to validate a candidate's qualifications using traditional methods, but there
are drawbacks such as security issues and time consumption. In this paper, a
blockchain-based academic certificate authentication system will be used to
ensure authenticity and make the assertion of the decentralized system secure.
However, the system will generate, authenticate and make corrections on
academic certificates. Ultimately, some blockchain-based authentication systems
already exist, they can't correct any errors that occur during generation. The
proposed system will help in many ways, such as providing a user-friendly
university admission, and smooth job hiring process, etc. In conclusion, our
proposed system can permanently eradicate certificate forgeries and create and
promote trust in society.
