The Supply Blockchain Project is a feasibility study to explore how an industrial supply-chain can be implemented with blockchain technology. Particularly, we use an example from the automobile industry.
We also simulate the transportation and the selling of the car.
This project uses the hyperledger fabric blockchain together with the hyperledger composer tool.
Here is an architecture overview:
With the provided source code we handle the sensors for the Supply-Chain project. We use the MFRC522 Sensor with multiple Raspberry Pi. Each time the Sensor is triggered, we send a JSON object to a MQTT broker. A HTTP POST-Request will soon be possible.
The Project uses some code-snipptes from MFRC522-python
python3, git, python-pip3, python-dev, build-essential
sudo pip3 install RPi.GPIO
# also possible: python3 -m pip install RPi.GPIO
printf "device_tree_param=spi=on \ndtoverlay=spi-bcm2708\n" >> /boot/config.txt
sudo raspi-config In the menu select "5 Interfacing Options"
Select "SPI" (probably 4th entry)
When asked if you want to enable the SPI interface select ""
Exit menu with ""
Reboot your Raspberry Pi
sudo reboot
git clone https://github.com/lthiery/SPI-Py.git
cd SPI-Py
#It is super important to INSTALL WITH PYTHON3
sudo python3 setup.py install
pip3 install paho-mqtt python-etcd
cd ..
git clone https://github.com/Lebski/Supply-Blockchain
cd Supply-Blockchain/Chain_rfid
python3 scan.py
In another terminal you can run the listener.py. It listens to the default settings of scan.py(no flags needed).
These are the presettings:
receiver = "iot.eclipse.org" port = 1883 max_timeout = 60 topic = "supply/sensor1"
And then run the Skript:
python3 listener.py
