INTRODUCTION
 The traditional education systems are no standard for the necessity of including the most
advanced technology to enhance their entire consistency.
 Currently, the educational sector provides traditional certificates to the student after
completion of a degree.
 That means the copies need to deal with in person, they aren’t tamper-resistant and can be
lost anytime.
 In this case, Blockchain brings us a massive opportunity with a trustable interaction among
students, universities, and employers in the educational certificate verification process.

MOTIVATION
Educational certificate verification is the process of checking and verifying the certificate legitimacy of graduate
students. It is a costly, lengthy, and time-consuming procedure as university authorities invest millions of dollars
in maintaining the entire process each year. The employer also takes plenty of time to verify the authenticity of
the applicant’s certificate. The current certification system provides traditional certificates to the candidates.
That’s why certificates can be tampered with and lost at any time. Moreover, counterfeiting the certificates by
scammers and issued by many illegal institutions makes the process hazardous. People frequently lie about their
degrees and qualifications by counterfeiting certificates. A fake certificate generated by skilful scammers is
always tough to identify and address as the original one. Therefore, there is a crucial need to upgrade the
certification and verification process.

CONCLUSION
 In this Research Work, a Blockchain-based Educational Certificate Verification decentralized application
named DIUcerts was developed in the Ethereum Blockchain platform.
 The first objective of this research work was achieved by the progressive and effective implementation of the
proposed model and also developed DApp.
 This paper is introduced to avoid the middleman or any third party in the certificate verification process.
 One of our goals is to diminish the cost and time of the verification process. Surprisingly, this paper evaluates
the cost of the proposed decentralized app, and it cost less than a dollar without any server maintenance cost.
 However, the main challenge of this paper is to eradicate fake educational certificates and our DApp almost
met all the conditions to fight against this fraud and scam channel.
 In conclusion, from this work, this paper encourages that developers should be considered the Ethereum
Blockchain platform for developing decentralized applications on Blockchain and it will turn into an interesting
sector for the upcoming generation.
