Monad BFT

Overview

This repository contains implementation for the Monad consensus client and JsonRpc server. Monad consensus collects transactions and produces blocks which are written to a ledger filestream. These blocks are consumed by Monad execution, which then updates the state of the blockchain. The triedb is a database which stores block information and the blockchain state.

Getting Started

git submodule update --init --recursive

Using Docker

The most straightforward way to start a consensus client + an execution client + a JsonRpc server. Run the following:

1. cd docker/single-node
2. nets/run.sh

Using Cargo

To run a Monad consensus client, follow instructions here.

To run a JsonRpc server, follow instructions here.
