Blockchains Model Simulator

Folder structure

• src/ Contains the python source code files
• src/bcns Contains the core classes of the simulator
• src/run_eval.py This is the entry point, you can run the simulator by chosing a configuration. For example:
  • python3 run_eval.py -c "2" #for the P2P configuration or
  • python3 run_eval.py -c "2-c" #for the Coordinated configuration

Configurations can be modified or added at src/evaluation/SimulationConfigs.py

• evaluation_results/ contains the dataframes that contain all simulation results. These dataframes can be read and the results can be plotted using the notebook (BCNS-PLOTTER.ipynb)

• Data of the simulations in the paper and the plotter can be found at: https://drive.google.com/drive/u/4/folders/10ychGyYtrcoShLG9UmcTFnzCHsF3EWUj

Thanks!
