BITSIE (BITcoin SImulation Engine)

scripts and examples for running simulations against Bitcoin Core. this assumes you have already setup a hertzner account and setup the hertzner cli hcloud.

at a high level:

1. set up your server (setup_server.sh)
2. clone bitsie (git clone https://github.com/josibake/bitsie.git)
3. install dependencies (install_dependencies.sh)
4. create your baseline and feature worktrees (example below)
5. run simulations (run_sims.sh)

Running a simulation

After running setup_server.sh and install_dependencies.sh, ssh into your server (hcloud server ssh <server_name>) and setup your baseline and feature directories:

# make a new branch off of the simulation branch for rebasing onto master
git checkout coin-sel-sim-trace && git checkout -b sim-baseline && git rebase master 

# resolve any merge conflicts and create the baseline worktree

git worktree add ../baseline

# repeat the same steps for your feature branch
git checkout coin-sel-sim-trace && git checkout -b sim-feature && git rebase josibake-coin-selection-rebase

git worktree add ../feature

Next, run simulations for your baseline. Provide a scenario and feerates from the simulation scenarios repo and run the simulation X times (you can use the helper script run_sims.sh):

mkdir /root/sim-results
/root/bitsie/run_sims.sh /root/baseline/ 5 /root/sim-results/ /root/coin-selection-simulation/payments/bustabit-tiny-hot-wallet.csv /root/coin-selection-simulation/feerates/2019-2020-per-day.csv
