Blockchain Based Certificate Issuance and Verification System SmartCertify

Abstract

Modern digital era passing out very tough time due to cybercriminal activity, fraud etc. In this situation financial, reputation, and time losses is common concern. According to time of India news in case of the Manav Bharti University of Himachal Pradesh, where 36,000 fake degrees were sold, & the 2026 Prayagraj Pharmacy Scam incidents such as these have suffers free trust. So, this issue demanded to protect sensitive information and their secure management. Currently block chain is in prevalence for security due to its characteristic that have capability to reduce cybercriminal activity and effective management. In reality, our traditional education system is currently is facing of a big problem like increasing difficulty to verify the authenticity of academic degrees. Main reason behind problem is the education database systems which is in centralize based and all data is stored in the single location. So, this make possibility to hacking, and these systems also incline to be quite slow. So, to fight this situation in this paper present a block chain-based solution named "SmartCertify". It controls by smart contracts to eliminate any scope for fake activity. Basically, in this includes a "Rules-Based Governance" model, where regulatory bodies such as the UGC pre-configure seat limits directly onto the blockchain. If university attempts to fraud even single certificate beyond its allocated limit, the block chain will immediately block the transaction. For system security used cryptographic chaining tool, where every new certificate will cryptographically link to previous one. If anyone try to attempt to tamper with past records using tools like photoshop, complete chain will be broken, and fraud be instantly detected. This entire process operates on local "Ganache" blockchain, confirms complete transparency and security.
