## diffsim
diffsim is a program that simulates a bitcoin network. Its main purpose is to test existing difficulty algorithms and assist in developing a new algorithm.
### Install
First install go: [https://golang.org/doc/install](https://golang.org/doc/install)
Use the go tool to get and install the diffsim sources: `go get github.com/GeertJohan/diffsim`
### Usage
Simply run the application in a terminal. Use the `-v` flag to enable verbose logging.
```
diffsim -v
```
The application will ask you which algorithm and simulation to run.
Right now only one simulation and one algorithm is available, but more will become available soon.
### Contribute
I accept pull requests containing new simulations or difficulty re-adjustment algorithms.
If you wish to change something, please open an issue first to discuss the change.
### Example usage
```
$ diffsim
Which algorithm should be tested?
