beacon-kit

A modular and customizable consensus layer for Ethereum based blockchains

What is BeaconKit

BeaconKit introduces an innovative framework that utilizes the Cosmos-SDK to create a flexible, customizable consensus layer tailored for Ethereum-based blockchains. 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.

First there was EVM Compatibility; next, EVM Equivalence; and now with BeaconKit, EVM Identicality.

Why BeaconKit?

TODO: Talk about Polaris / Ethermint compatibility issue.

Supported Execution Clients

Through utilizing the Ethereum Engine API BeaconKit is able to support all 5 major Ethereum execution clients:

• Geth: Official Go implementation of the Ethereum protocol.
• Erigon: Formerly known as Turbo-Geth, it is a more performant and feature-rich Ethereum client forked from go-ethereum.
• Nethermind: .NET based Ethereum client with full support for Ethereum and other blockchain protocols.
• Besu: An enterprise-grade Ethereum client developed under the Apache 2.0 license and written in Java.
• Reth: A Rust-based Ethereum client, focusing on performance and reliability.

Documentation

BeaconKit leverages pkgsite for it's core documentation, you can run pkgsite locally and run a web-ui of the latest documentation:

make pkgsite

Running a Local Development Network

Prerequisites:

• Docker
• Golang 1.22.0+
• Foundry

Start by opening two terminals side-by-side:

Terminal 1:

# Start the sample BeaconKit Consensus Client:
make start

Terminal 2:

# Start an Ethereum Execution Client:
make start-reth # or start-geth start-besu start-erigon start-nethermind
