• AASTHA GABA - 242IS035
• ===========================================================* This project demonstrates a lightweight blockchain consensus mechanism, called PoEM (Proof of Evolutionary Model), tailored for IoT and BaaS environments. The simulation runs on a Mininet virtual network, using Ryu SDN Controller to manage topology and traffic.

Components

• Mininet: Network emulation platform.
• Ryu Controller: OpenFlow-based SDN controller.
• PoEM Nodes: Each host runs a lightweight ML model (Logistic Regression) and participates in consensus.
• UDP Messaging: Used for communication between nodes.

Installation Steps

1. Install Mininet

---

sudo apt-get update
sudo apt-get install mininet

2. Set Up Python Environment with Ryu

---

# Add deadsnakes PPA and install Python 3.9
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt install python3.9 python3.9-distutils virtualenv

# Create and activate virtual environment
virtualenv -p `which python3.9` ryu-python3.9-venv
source ryu-python3.9-venv/bin/activate

# Install Ryu
sudo apt-get install python3-ryu

# Fix eventlet compatibility
pip uninstall eventlet
pip install eventlet==0.30.2

# Verify Ryu installation
ryu --version
ryu-manager --version

---

Running the Simulation

1. Launch Ryu Controller

---

ryu-manager --ofp-tcp-listen-port 6633 ryu.app.simple_switch_13

2. Clear Mininet State (Optional)

---

sudo mn -c

3. Start the Mininet Topology and PoEM Nodes

---

sudo python3 /home/student/block_chain/poem_topo.py
