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:
-
Using run_simulation.py to run a single simulation:
cd PHANTOM python -m phantom.network_simulation.run_simulation -
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.
