IBC: An Integrated Framework Combining Blockchain with BPMN Choreography

Main Features

• Multi-party collaborative model management: IBC provides a multi-party collaborative model management platform, which can be used to manage the life cycle of models, including model creation, modification, deletion, and version management.
• Physical resources construction: IBC could quickly build blockchain as you need.
• BPMN choreography modeling and executing: IBC provides a visualized BPMN choreography modeling tool, which can be used to model the business process of multi-party collaboration.

Requirements

GCC and Make

sudo apt-get install build-essential

Python3

sudo apt-get install python3-dev

libgraphviz-dev

apt-get update && apt-get install -y gettext-base graphviz libgraphviz-dev && apt-get autoclean && apt-get clean && apt-get autoremove && rm -rf /var/cache/apt/

Database Configuration

Using docker compose to start the database service.

docker-compose -f docker-compose.yml up -d

backend Configuration

Dependency

pip install -r requirements.txt

recommended to use python-venv.

Setting up the database

python3 manage.py makemigrations
python3 manage.py migrate

---

agent Configuration

Dependency

pip install -r requirements.txt

Recommended to use python-venv.

Start the agent

gunicorn server:app -c ./gunicorn.conf.py
