E-Certify

Blockchain Based Certificate Validation

E-Certify : About

• 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

Installation

For Development

- 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. ------------------------------------- ## Contributing - We're are open to enhancements & bug-fixes. - Feel free to add issues and submit patches. ## Authors - Atharva Udapure - atharvau - Nikhil Sahu - nikhildsahu - Gaurav Sharma - gauravsharma-gs
