Certificate Verification using Blockchain & IPFS

Inspiration

The inspiration for this project came upon mainly to resolve the manual work of verifying marksheets and to check the genuinity of the marksheets provided by the institution/university.

What it does

• The purpose of this project is to reduce the time taken for the certificate verification process.
• To keep the records safely in the Block Chain network without any third-party involvement in a decentralized environment safely.

Certificate Authority

Admin Side

• Admin uploads the student details from the database.
• Admin uploads the marksheet in IPFS.
• Generated hash is stored in the blockchain network.
• On the request of the user, login credentials are given.

- By using that, the user can login and verify their certificates/marksheets.

User Side

• Request the login credentials from the admin.
• After receiving the login credentials, they can login & can upload their certificate.
• On clicking the verify option, a hash is generated & that hash is checked with the hash that has already been stored in the block chain network.

1. If the same images are uploaded, the hashes generated will be equal & genuine.
2. If the uploaded image is different, a different hash will be generated.

How we built it

• We built this using remix.xinfin.network using XDCpay, solidity, React js , jquery, bootstrap.
• The Certificates are stored and retrieved using IPFS.

Challenges we ran into

• The challenges we ran into were to minimize the transaction fees per transaction.
• Keeping up with the current technology & updates which supports the solidity and other blockchain works.

Accomplishments that we're proud of

.

• We were able to store & retrieve the data(certificate) and hash from the blockchain which helps many institutions, companies to reduce cost and time.
• What we learned
• After uploading a data in the blockchain network it is impossible to hack.
• By implementing this technology for this problem, any change in the blockchain network can be identified easily - Counterparty risk removal
• (No Alteration).
• Trust maximized agreement – Unbreakable promises.

What's next for Certificate Verification

• We are planning to implement the Certification Verification mechanism using blockchain concept in our college and in a large-scale market.
• We are also going to implement this by creating an app by which a large amount of people can benefit with just a click of a button.
