P2P-Blockchain-Simulator

Simulation of a P2P Cryptocurrency Network - CS 765, Spring 2023

Installation

To extract the file from ubuntu, extract the zip folder using unzip RollNo1_RollNo2_RollNo3.zip

To clone from github repo git clone https://github.com/ankitkmisra/P2P-Blockchain-Simulator.git

The code for selfish mining and stubborn mining is inside the folders selfish and stubborn. To run them we need to change our directory into those folders as given below

Instruction to Run

• Step 1: Open the folder RollNo1_RollNo2_RollNo3 using cd RollNo1_RollNo2_RollNo3
  • Step 1.1: To run the selfish mining code open the folder selfish as: cd selfish
  • Step 1.2: To run the stubborn mining code open the folder stubborn as: cd stubborn
• Step 2: To install required libraries pip install networkx numpy matplotlib
• Step 3: To run as default parameters, use the command as mentioned below python3 main.py

The results would get written down inside the figures and logs folders.

To change various parameters usage as mentioned below

• number of nodes in the P2P network: -n or --num_nodes
• percentage of slow nodes: -z0 or --fraction_slow
• the adversary mining power: -a or --alpha
• percentage of nodes adversary is connected to: -zeta or --zeta
• percentage of nodes having low CPU power: -z1 or --fraction_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
• use this flag to save all figures generated in ./figures: -s or --save_figures

For example python3 main.py -n 10 -z0 0.5 -z1 0.5 -ttx 10 -I 1000 -T 10000 -s

To get help regarding any paramenter: python3 main.py -h will give the description on usage

Usage

usage: python3 main.py [-h] [-n NUM_NODES] [-z0 PERCENTAGE_SLOW] [-z1 PERCENTAGE_LOWCPU] [-a ALPHA] [-zeta ZETA] [-ttx MEAN_INTER_ARRIVAL] [-I AVERAGE_BLOCK_MINING_TIME] [-T SIMULATION_TIME] [-s]
