PHANTOM (GhostDAG)

Presented here is an efficient implementation of the PHANTOM block-DAG protocol.

This package includes:

• An interface for block-DAGs.
• Various implementations of the PHANTOM block-DAG protocol:
  • a brute force optimal coloring implementation
  • a greedy approximating coloring implementation
• A simulation framework to test out block-DAGs adhering the the aforementioned interface. Almost every parameter is modifiable: network topology, average network delay, hash-rate distribution, etc'.
• An implementation of a chain-diversion attack against the PHANTOM protocol.

Installation

There are two methods of installation:

• Download the repository and run:

    cd PHANTOM
    pip install .
  

• Download the repository and run:

    cd PHANTOM
    python setup.py install  
  

Usage

There are two ways to run the simulation:

1. Using run_simulation.py to run a single simulation:

    cd PHANTOM
    python -m phantom.network_simulation.run_simulation
   

2. Using analyze_attack_success_rate.py to run multiple simulations on various combinations of run-time parameters to to analyze the success rate of a given attack on given block-DAG protocols.

    cd PHANTOM
    python -m phantom.network_simulation.analyze_attack_success_rate
   

All parameters relevant for each run method are contained in the run script and can easily be changed.
