# `ethshadow`: Discrete-event Ethereum network simulations

<!--- ANCHOR: overview (for mdbook) -->

Ethshadow is a tool to easily configure and run simulated Ethereum networks. Under the hood, it uses
[Shadow](https://shadow.github.io/), a discrete-event network simulator that enables us to run simulations with actual
Ethereum clients instead of specifically written simulation code.

Check out the [guide](https://ethereum.github.io/ethshadow) to get started!
The advantages of using Ethshadow are as follows.

1. It already includes everything in the simulation (e.g. libp2p, discv5, etc).
2. It uses the same software as the mainnet and the public testnets.
3. If there is any upgades in lighthouse, we can integrate those upgrades easily in the simulation.

If you want to simulate a new Ethereum protocol, what you need to do is just to implement it in lighthouse or geth or
any other supported EL and CL clients and run it using this simulator.

<!--- ANCHOR_END: overview (for mdbook) -->

## Quickstart

Install Ethshadow.
```
cargo install --path .
```

Save the following file to a config file `myfirstsim.yaml`.

```yaml
general:
# How much time should we simulate?
stop_time: 20min
# Display a progress indicator?
progress: true

ethereum:
# Distribute this many validators evenly across all nodes
validators: 50
# Create this many nodes with Geth, Lighthouse and a Validator client.
# Additionally, a host with one boot node for CL and EL each is added.
nodes: 10
```
Run the simulation.
```shell
ethshadow myfirstsim.yaml
```

## Supported clients

<!--- ANCHOR: supported-clients (for mdbook) -->

✅ = Available, works out-of-the-box with latest release
🚧 = Available, works with modifications (see subpage for details)
❌ = Unavailable, does not currently work
❔ = Unavailable, not yet tested

A client is considered to work if it can follow the chain and perform the necessary duties for validating. Other
features might not work.
