Build guide

Requirements: to run an Aleo node effectively, you'll need:

OS: Latest 64-bit architecture
CPU: 16-32 cores
RAM: 16-64GB
Storage: 64GB - 2TB
Network: Symmetric, high-speed
GPU: Optional for Provers

2. Installation

Before beginning, please ensure your machine has Rust v1.66+ installed. Instructions to install Rust can be found here.

https://www.rust-lang.org/tools/install

Clone the repository: begin by cloning the snarkOS GitHub repository to your local machine.

git clone https://github.com/AleoHQ/snarkOS.git --depth 1

Install Dependencies: run the Ubuntu build script to install necessary dependencies.

cd snarkOS ./build_ubuntu.sh

Install snarkOS: use Cargo to install snarkOS.

cargo install --locked --path .

Ensure ports 4130/tcp and 3030/tcp are open on your router and OS firewall.

3. Run an Aleo Node: run an Aleo client

Start by following the instructions in the Build Guide.

https://github.com/AleoHQ/snarkOS#2-build-guide

Next, to start a client node, from the snarkOS directory, run:

./run-client.sh

3. Run an Aleo Node: run an Aleo Prover

Start by following the instructions in the Build Guide.

https://github.com/AleoHQ/snarkOS#2-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. Command Line Interface

To run a node with custom settings, refer to the options and flags available in the snarkOS CLI.

The full list of CLI flags and options can be viewed with snarkos --help:

5. Development guide

Quick start:

Initialize validators, provers, and clients to kickstart development.
Utilize tmux for local devnet setup.
Toggle between nodes and manage node selection effortlessly.

Operations. It's essential to initialize nodes starting from 0 and incrementing by 1 for each new node. Use the following options to initialize a node:

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

Local Devnet:

Install tmux: Start by installing tmux on your system.
Start a Local Devnet: Run the devnet script to begin a local development network.

./devnet.sh

Follow the instructions in the terminal to start the devnet.

View a Local Devnet:
- Switch Nodes: Toggle between nodes using Ctrl+b n and Ctrl+b p.
- Select a Node: Choose a node manually or using shortcuts.

Clean up. To stop a local devnet and clean up node storage, use the following command:

Ctrl+b :kill-session cargo run --release -- clean --dev <NODE_ID>

With these steps, you're all set to explore the vast possibilities of building zero-knowledge applications on Aleo with snarkOS. Happy coding!
