CryptoBonds is a blockchain application that was built using Hyperledger Sawtooth. The goal of the project is to make a stable coin with its value linked to real life company bonds. CryptoBonds acts as a clearing firm and monitors transactions between the banks and the traders. Traders are able to exchange cryptobonds and other cryptocurrencies with other users.

CryptoBonds is developed by a team of five people at HackIllinois 2019, with the help of mentors from Hyperlegder and Docker opensource community.

Installation

Cryptobonds application runs on two servers. One of them is a web application for client interaction involving banks, companies and traders. The other server is where blockchain is setup. To setup blockchain node server on your machine, please refer to this repository

Web App setup

This application is built using python Django framework deployed on heroku.

Being a PythonWeb framework, Django requires Python. See What Python version can I use with Django?

1. Install pip

$ sudo apt-get install python3-pip

Note: If your distribution already has pip installed, you might need to update it if it’s outdated

2. Set up a virtual environment

It’s a good idea to keep all your virtualenvs in one place, for example in .virtualenvs/ in your home directory. Create it if it doesn’t exist yet

$ mkdir ~/.virtualenvs

Now create a new virtualenv by running:

$ python3 -m venv ~/.virtualenvs/djangodev

On some versions of Ubuntu the above command might fail. Use the virtualenv package instead

$ pip3 install virtualenv
$ virtualenv --python=`which python3` ~/.virtualenvs/djangodev

The final step in setting up your virtualenv is to activate it:

$ source ~/.virtualenvs/djangodev/bin/activate

If the source command is not available, you can try using a dot instead:

$ . ~/.virtualenvs/djangodev/bin/activate

3. Install Django

After you’ve created and activated a virtual environment, enter the command

$ pip3 install Django 

4. Clone repository and run server locally

Clone repository using following command

git clone https://github.com/crypto-bonds/django-client.git

To run server locally

cd django-client
python manage.py migrate
python manage.py runserver

5. Run server on heroku

To get the code up and running on your device follow the instructions here: https://devcenter.heroku.com/articles/django-app-configuration
