P2P-Blockchain-Network-Simulator

A discrete-event blockchain simulator for a P2P cryptocurrency network.

How to Run (Ubuntu/Debian)?

• Setup the Project - bash setup.sh
• Activate the Virtual Environment - source venv/bin/activate
• Run as default parameters - python3 lib/main.py

How to change default parameters?

• number of nodes in the P2P network: -n or --num_nodes
• percentage of slow nodes: -z0 or --percentage_slow
• percentage of nodes having low CPU power: -z1 or --percentage_lowcpu
• mean inter-arrival time between transactions: -ttx or --mean_inter_arrival
• average time taken to mine a block: -I or --average_block_mining_time
• total time for which the P2P network is simulated: -T or --simulation_time

Example - python3 main.py -n 10 -z0 0.5 -z1 0.5 -ttx 10 -I 600 -T 6000

Where are the simulation outputs saved?

Network graph, Blockchain graph and log for each node is saved inside lib/outputs folder after the end of simulation.
