Academic Certificates on the Blockchain

The academic certificate verification platform using blockchain technology is used to issue, manage and verify academic certificates in a secure and distributed manner. This project addresses the need for a secure digital platform to issue and verify academic certificates without intervention from the original certificate issuer (University).


The core functionality of this application are :

  • Create and issue academic certificates.
  • Manage and share academic certificates.
  • Verify authenticity of shared certificates.

Architecture Overview


The following technologies are used on the application

  • Hyperledger Fabric: Used to build the blockchain network, run smart contracts. Fabric CA is used to enroll members in the network.
  • Node.js: Backend of the web application is built in nodeJS runtime using the express framework. Chaincode is also written in NodeJS.
  • MongoDB: The user and certificate data is stored in MongoDB database.
  • Bootstrap: The front-end of the web application is built using bootstrap, ejs & jQuery.

Network Users

The users of the platform include - Universities, Students and Certificate Verifiers (Eg - Employers). The actions that can be performed by each party are as follows


  • Issue academic certificates.
  • View academic certificates issued.
  • Endorse Verification and digitally sign academic certificates.


  • Receive academic certificates from universities.
  • View and manage received academic certificates.
  • Share academic certificates with third party verifiers.
  • Selective disclosure of certificate data.


  • Receive certificate data from students.
  • Verify certificate authenticity with blockchain platform.

To learn more about how selective disclosure and decentralized verifications work, read about verifiable credentials.

Getting Started

IMPORTANT NOTE: The instructions for building this project are out of date. I'm unfortunately not in a position right now to test and update these instructions. If you're able to get the project up and running properly. a pull request to update the following instructions is appreciated!

Related Issue: #4


In order to install the application, please make sure you have the following installed with the same major version number.

  1. Hyperledger fabric version 2.1.x.

  2. Node version 12.x.

  3. MongoDB version 4.0.x

  4. Latest version of NPM package manager

Starting Fabric Network

  1. Clone the repo

    git clone
  2. Start the fabric test-network with couchdb

    # at fabric-samples
    cd test-network
    ./ up createChannel -ca -c mychannel -s couchdb
  3. Package the chaincode situated in the chaincode directory.

    1. Follow the instructions here
    2. Note: Make sure in the final package instruction to name the package appropriately. By default it's named fabcar_1
  4. Install the chaincode according to the instructions here.(I'm referencing the instructions for Fabric version 2.1, please switch to the docs of your appropriate installed version).

Starting Web Application

Make sure mongodb and fabric network are running in the background before starting this process.

  1. Go to web-app
    # at blockchain-academic-certificates
    cd web-app
  2. Install all modules
    npm install
    npm install --only=dev  # For dev dependencies
  3. Create .env file
    touch .env 
  4. Specify environment variables in .env file.
    1. Specify MONGODB_URI_LOCAL to your mongodb database.
    2. Specify EXPRESS_SESSION_SECRET as a long random secret string.
    3. Specify CCP_PATH as the connection profile of org1 in your test network. The path for this should be ~/fabric-samples/test-network/organizations/peerOrganizations/
    4. In FABRIC_CHANNEL_NAME and FABRIC_CHAINCODE_NAME specify the channel and chaincode label respectively used during fabric network installation.
    5. Sample .env file
      MONGODB_URI_LOCAL = mongodb://localhost:27017/blockchaincertificate
      PORT = 3000
      LOG_LEVEL = info
      EXPRESS_SESSION_SECRET = sdfsdfddfgdfg3242efDFHI234 
      CCP_PATH = /home/tasin/fabric-samples/test-network/organizations/peerOrganizations/
      FABRIC_CHANNEL_NAME = mychannel
      FABRIC_CHAINCODE_NAME = fabcar_1
  5. Start the server in development mode
    npm run start-development
