1. Overview
snarkOS is a decentralized operating system for zero-knowledge applications. This code forms the backbone of Aleo network, which verifies transactions and stores the encrypted state applications in a publicly-verifiable manner.
2. Build Guide
2.1 Requirements
The following are minimum requirements to run an Aleo node:
- OS: 64-bit architectures only, latest up-to-date for security
- Clients: Ubuntu 22.04 (LTS), macOS Ventura or later, Windows 11 or later
- Provers: Ubuntu 22.04 (LTS), macOS Ventura or later
- Validators: Ubuntu 22.04 (LTS)
- CPU: 64-bit architectures only
- Clients: 16-cores
- Provers: 32-cores (64-cores preferred)
- Validators: 32-cores (64-cores preferred)
- RAM: DDR4 or better
- Clients: 16GB of memory
- Provers: 32GB of memory (64GB or larger preferred)
- Validators: 64GB of memory (128GB or larger preferred)
- Storage: PCIe Gen 3 x4, PCIe Gen 4 x2 NVME SSD, or better
- Clients: 64GB of disk space
- Provers: 128GB of disk space
- Validators: 2TB of disk space (4TB or larger preferred)
- Network: Symmetric, commercial, always-on
- Clients: 100Mbps of upload and download bandwidth
- Provers: 250Mbps of upload and download bandwidth
- Validators: 500Mbps of upload and download bandwidth
- GPU:
- Clients: Not required at this time
- Provers: CUDA-enabled GPU (optional)
- Validators: Not required at this time
Please note to run an Aleo Prover that is competitive, the machine will require more than these requirements.
2.2 Installation
Before beginning, please ensure your machine has Rust v1.66+ installed. Instructions to install Rust can be found here.
Start by cloning this Github repository:
git clone https://github.com/AleoHQ/snarkOS.git --depth 1
Next, move into the snarkOS directory:
cd snarkOS
[For Ubuntu users] A helper script to install dependencies is available. From the snarkOS directory, run:
./build_ubuntu.sh
Lastly, install snarkOS:
cargo install --path .
Please ensure ports 4133/tcp and 3033/tcp are open on your router and OS firewall.
3. Run an Aleo Node
3a. Run an Aleo Client
Start by following the instructions in the Build Guide.
Next, to start a client node, from the snarkOS directory, run:
./run-client.sh
3b. Run an Aleo Prover
Start by following the instructions in the Build Guide.
Next, generate an Aleo account address:
snarkos account new
This will output a new Aleo account in the terminal.
Please remember to save the account private key and view key. The following is an example output:
Attention - Remember to store this account private key and view key.
Private Key APrivateKey1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx <-- Save Me And Use In The Next Step
View Key AViewKey1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx <-- Save Me
Address aleo1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx <-- Save Me
Next, to start a proving node, from the snarkOS directory, run:
./run-prover.sh
When prompted, enter your Aleo private key:
Enter the Aleo Prover account private key:
APrivateKey1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
4. FAQs
1. My node is unable to compile.
- Ensure your machine has
Rust v1.66+installed. Instructions to install Rust can be found here. - If large errors appear during compilation, try running
cargo clean. - Ensure
snarkOSis started using./run-client.shor./run-prover.sh.
2. My node is unable to connect to peers on the network.
- Ensure ports
4133/tcpand3033/tcpare open on your router and OS firewall. - Ensure
snarkOSis started using./run-client.shor./run-prover.sh.
3. I can't generate a new address
- Before running the command above (
snarkos account new) trysource ~/.bashrc - Also double-check the spelling of
snarkos. Note the directory is/snarkOS, the command issnarkos
5. Command Line Interface
To run a node with custom settings, refer to the full list of options and flags available in the snarkOS CLI.
The full list of CLI flags and options can be viewed with snarkos --help:
snarkOS
The Aleo Team <hello@aleo.org>
USAGE:
snarkos [OPTIONS] <SUBCOMMAND>
OPTIONS:
-h, --help Print help information
-v, --verbosity <VERBOSITY> Specify the verbosity [options: 0, 1, 2, 3] [default: 2]
SUBCOMMANDS:
account Commands to manage Aleo accounts
clean Cleans the snarkOS node storage
help Print this message or the help of the given subcommand(s)
start Starts the snarkOS node

The following are the options for the snarkos start command:
USAGE:
snarkos start [OPTIONS]
OPTIONS:
--network <NETWORK_ID> Specify the network ID of this node [default: 3]
--validator Specify this node as a validator
--prover Specify this node as a prover
--client Specify this node as a client
--private-key <PRIVATE_KEY> Specify the node's account private key
--private-key-file <PRIVATE_KEY_FILE> Specify the path to a file containing the node's account private key
--node <IP:PORT> Specify the IP address and port for the node server [default: 0.0.0.0:4133]

6. Development Guide
6.1 Quick Start
In the first terminal, start the first validator by running:
cargo run --release -- start --nodisplay --dev 0 --validator
In the second terminal, start the second validator by running:
cargo run --release -- start --nodisplay --dev 1 --validator
In the third terminal, start the third validator by running:
cargo run --release -- start --nodisplay --dev 2 --validator
In the fourth terminal, start the fourth validator by running:
cargo run --release -- start --nodisplay --dev 3 --validator
From here, this procedure can be used to further start up provers and clients.
6.2 Operations
It is important to initialize the nodes starting from 0 and incrementing by 1 for each new node.
The following is a list of options to initialize a node (replace <NODE_ID> with a number starting from 0):
cargo run --release -- start --nodisplay --dev <NODE_ID> --validator
cargo run --release -- start --nodisplay --dev <NODE_ID> --prover
cargo run --release -- start --nodisplay --dev <NODE_ID> --client
cargo run --release -- start --nodisplay --dev <NODE_ID>
When no node type is specified, the node will default to --client.
6.3 Local Devnet
6.3.1 Install tmux
To run a local devnet with the script, start by installing tmux.
To install tmux on macOS, you can use the Homebrew package manager.
If you haven't installed Homebrew yet, you can find instructions at their website.
# Once Homebrew is installed, run:
On Ubuntu and other Debian-based systems, you can use the apt package manager:
There are a couple of ways to use tmux on Windows:
Using Windows Subsystem for Linux (WSL)
- First, install Windows Subsystem for Linux.
- Once WSL is set up and you have a Linux distribution installed (e.g., Ubuntu), open your WSL terminal and install
tmuxas you would on a native Linux system:
6.3.2 Start a Local Devnet
To start a local devnet, run:
./devnet.sh
Follow the instructions in the terminal to start the devnet.
6.3.3 View a Local Devnet
Switch Nodes (forward)
To toggle to the next node in a local devnet, run:
Ctrl+b n
Switch Nodes (backwards)
To toggle to the previous node in a local devnet, run:
Ctrl+b p
Select a Node (choose-tree)
To select a node in a local devnet, run:
Ctrl+b w
Select a Node (manually)
To select a node manually in a local devnet, run:
Ctrl+b :select-window -t {NODE_ID}
6.3.4 Stop a Local Devnet
To stop a local devnet, run:
Ctrl+b :kill-session
Then, press Enter.
Clean Up
