- It is a blockchain based project for online certificate validation.
- The major problem of counterfeit certificates can be tackled with the help of E-Certify, as it provides a solution to preserve the genuineness of a certificate.
- It works on the idea that: “Only the issuer can upload the certificate and the rest people can only view it.” The entire process works on the blockchain in partnership with the IPFS(to provide data security).
- Does Everything for Certificates : Storing ,Validating and Sharing .
- Thus this is a modern and hassle-free solution to manage certificates and verify them!
- This Project was made at SIH 2019
- It is D-App on Ethereum.
- Back-End has Smart Contract
- Front-end of our Web-App is made with React.Js and our complete frontend components are available at @gauravsharma-gs /dapper-ui (visit)
- All User-Data is stored on IPFS also every data is first encryted locally and then send to ipfs to have more security
- It create Multi-Sig Wallets for every student where both Student and his/her Institute is Owner.
- We are using Metamask Browser Extension to work with Ethereum.
- We have used Truffle for testing our project

We are using Truffle for testing and development of this project.
-
Also you need to have Metamask Browser Extension.
-
For setting up Truffle (more detailed instruction are avalaible here )
-
Steps :
- Clone the repo
$ git clone https://github.com/nikhildsahu/E-Certify.git
-
Setup Truffle
- Install truffle
$ npm install -g truffle
- Unbox React inside any Directory
$ truffle unbox react
- Inside that Directory
- Now replace Contracts folder with Contracts folder present in Repo.
- Also Copy Complete Repo content in to Client folder.
- Run the development console
$ truffle develop
- Compile and migrate the smart contracts.
compile
migrate
- In the client directory, we run the React app.
// in another terminal (i.e. not in the truffle develop prompt)
$ cd client
$ npm run start
-
Open http://localhost:3000 to view it in the browser.
-
Import Account on Metamask with keys given by Truffle .
-
Testing and Development can be done on these Accounts.
-
Smart contract changes must be manually recompiled and migrated then only it will work.
- We're are open to enhancements & bug-fixes.
- Feel free to add issues and submit patches.
