A secure & efficient solution for Certificate Verification

DeCerts is a blockchain-based application that will store and verify documents issued by the college to the students. Before uploading the file on IPFS, a QR Code is generated which is then embedded in the document. Issuance of certain documents, for instance an academic transcript requires a fee of Rs. 400. Whenever a third party(University/Company) wants to verify the document, they can scan the QR Code and verify it. There is a small fee associated with the verification process.
Biconomy has been used to implement Gasless transactions and IPFS to store the documents.

Flowchart

Workflow (Two Approaches)

Problems with the current system

• Companies/Universities are concerned whether a certificate provided to them is legit or forged.
• Manual verification/offline visits is a tedious procedure and takes weeks to complete.
• Use of physical documents is also inconvenient and inefficient in today’s fast paced digital world.
• Physical documents can be misplaced easily.

How we aim to solve these problems

• Use of blockchain to maintain integrity and for authentication.
• Use of IPFS storage to store all the documents digitally on a decentralized network.
• Automation of the verification system using QR code.
• 2FA for student authentication.
• Use of polygon network for faster and cheaper transactions.
• Biconomy for gasless transactions.
