## What is BeaconKit?
[BeaconKit](https://docs.berachain.com/learn/what-is-beaconkit) is a modular framework for building EVM based consensus clients.
The framework offers the most user-friendly way to build and operate an EVM blockchain, while ensuring a functionally identical execution environment to that of the Ethereum Mainnet.
## Supported Execution Clients
Through utilizing the [Ethereum Engine API](https://github.com/ethereum/execution-apis/blob/main/src/engine)
BeaconKit is able to support all 6 major Ethereum execution clients:
- [**Geth**](https://geth.ethereum.org/): Official Go implementation of the Ethereum protocol.
- [**Erigon**](https://erigon.tech/): More performant, feature-rich client forked from `go-ethereum`.
- [**Nethermind**](https://www.nethermind.io/): .NET based client with full support for Ethereum protocols.
- [**Besu**](https://www.lfdecentralizedtrust.org/projects/besu): Enterprise-grade client, Apache 2.0 licensed, written in Java.
- [**Reth**](https://reth.rs/): Rust-based client focusing on performance and reliability.
- [**Ethereumjs**](https://ethereumjs.readthedocs.io/en/latest/#): Javascript based client managed by the Ethereum Foundation.
## Running a Local Development Network
**Prerequisites:**
- [Docker](https://docs.docker.com/engine/install/)
- [Golang 1.23.0+](https://go.dev/doc/install)
- [Foundry](https://book.getfoundry.sh/)
Start by opening two terminals side-by-side:
**Terminal 1:**
```bash
# Start the sample BeaconKit Consensus Client:
make start
```
**Terminal 2:**
**Note:** This must be run *after* the `beacond` node is started since `make start` will populate the
eth-genesis file used by the Execution Client.
```bash
# Start an Ethereum Execution Client:
make start-reth # or start-geth start-besu start-erigon start-nethermind start-ethereumjs
```
The account with
`private-key=0xfffdbb37105441e14b0ee6330d855d8504ff39e705c3afa8f859ac9865f99306`
corresponding with `address=0x20f33ce90a13a4b5e7697e3544c3083b8f8a51d4` is
preloaded with the native EVM token.
## Multinode Local Devnet
Please refer to the [Kurtosis README](https://github.com/berachain/beacon-kit/blob/main/kurtosis/README.md) for more information on how to run a multinode local devnet.
