Mixnet v2 Simulation

How to run

Make sure that all dependencies specified in the requirements.txt in the project root, and run the following command to run the simulation:

python main.py

The following parameters can be configured:

usage: main.py [-h] [--running-time RUNNING_TIME] [--num-nodes NUM_NODES] [--num-mix-layers NUM_MIX_LAYERS]

Run simulation

options:
  -h, --help            show this help message and exit
  --running-time RUNNING_TIME
                        Running time of the simulation (default: 30)
  --num-nodes NUM_NODES
                        Number of nodes in the network (default: 2)
  --num-mix-layers NUM_MIX_LAYERS
                        Number of mix layers in the network (default: 2)

Development Status

Modified Sphinx without encryption
Naive P2P 1:N broadcasting
Forwarding messages through mixes, and then broadcasting messages to all nodes
Naive cover traffic with a constant rate
Naive random delays in mix
Adversary simulations
Reporting & Visualization
More realistic P2P broadcasting (e.g. gossipsub)
More sophisticated cover traffic (e.g. based on the approximate block interval)
More sophisticated mix delays (e.g. Poisson)
Modified Sphinx with encryption
