v0.1.0 — Initial GHOSTDAG Simulator Release

v0.1.0 — Initial Release

First public release of ghostdagsim, an ns-3/MPI network simulator
for the GHOSTDAG consensus protocol.

What's included

• GHOSTDAG ordering algorithm with blue/red block classification
• Honest miner model with Poisson block generation
• Inv-based block and transaction propagation
• Geographic P2P topology with Pareto latency modeling
• MPI distributed simulation support
• Metrics collection
• Unit tests for DAG and mempool logic

Requirements

• ns-3.46+ with MPI enabled
• CMake 3.10+, C++17, MPI implementation

Quick start

See README for build and run instructions or use Pre-built docker image described below.

Known limitations

• Only honest miner strategy implemented (attacker modeling planned)
• Tested with up to 1000 nodes on MPI; large-scale stress testing ongoing

Pre-built docker image

docker pull ghcr.io/eramoss/ghostdagsim:0.1.0

Run

docker run --rm \
  -v $(pwd):/results \
  -e MPI_THREADS=4 \
  ghcr.io/eramoss/ghostdagsim:0.1.0 \
  -- --nodes=20 --miners=10 --blocks_per_miner=50

or you can use also -e MPI_ARGS="args..." to pass any mpi argument that you need
