The Open Mina Node

The Open Mina Node is a Mina node written completely in Rust and capable of verifying blocks of transactions, producing blocks and generating SNARKs.

In the design of the Open Mina node, we are utilizing much of the same logic as in the Mina Web Node. The key difference is that unlike the Web Node, which is an in-browser node with limited resources, the Open Mina node is able to perform resource-intensive tasks such as SNARK proof generation.

Overview of the Node’s current functionalities

Currently, with the Open Mina node, you can:

• Connect to the network and sync up to the best tip block
• Validate and apply new blocks and transactions to update consensus and ledger state.
• Produce SNARKs to complete SNARK work.
• Broadcast messages: blocks, SNARK pool

We are working on the following:

• Produce SNARKs in Rust (currently we use OCaml subprocess for that)

In the future, we plan to implement:

• Direct transfer of MINA funds
• Block production
• SNARK proof generation for transactions
• SnarkyJS support for Rust node, thanks to which you will be able to directly inject simple transactions, such as transferring Mina funds from one account to another.
• The ability to record/replay all blocks

How to launch (with docker compose):

Run:

docker compose up

Then visit http://localhost:8070 in your browser.

By default, docker compose up will use the latest node and frontend images available (tagged with latest), but specific versions can be selected by using the OPENMINA_TAG and OPENMINA_FRONTEND_TAG variables.

How to launch (without docker compose):

This installation guide has been tested on Debian and Ubuntu and should work on most distributions of Linux.

Pre-requisites:

Ubuntu or Debian-based Linux distribution with the following packages installed:

• curl
• git
• libssl-dev
• pkg-config

Example:

# Either using "sudo" or as the "root" user
sudo apt install curl git libssl-dev pkg-config

Steps (for Debian-based Linux distros):

Open up the command line and enter the following:

And then:

# Install rustup and set the default Rust toolchain to 1.77 (newer versions work too)
curl https://sh.rustup.rs -sSf | sh -s -- -y --default-toolchain 1.77
# Setup the current shell with rustup
source "$HOME/.cargo/env"
# Clone the openmina repository
git clone https://github.com/openmina/openmina.git
cd openmina/
# Build and run the node
cargo run --release -p cli node

How to launch the UI:

Prerequisites

1. Node.js v20.11.1

MacOS

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
brew install node@20.11.1

Linux

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
source ~/.bashrc
nvm install 20.11.1

Windows

Download Node.js v20.11.1 from the official website, open the installer and follow the prompts to complete the installation.

2. Angular CLI v16.2.0

npm install -g @angular/cli@16.2.0

3. Installation

Open a terminal and navigate to this project's root directory

cd PROJECT_LOCATION/openmina/frontend

Install the dependencies

npm install

Run the application

npm start
