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.

Workflow (Two Approaches)

Untitled Diagram

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.
  • Use of celo Testnet network for deployment of the contract and performnig Transactions.
