Welcome to the world of Aleo instructions and snarkVM! In this tutorial, we'll delve into the intermediate representation of Aleo programs and the tools necessary for compiling and executing them. I'm Heorhii, and I'll be your guide on this journey through Aleo's programming ecosystem.

Introduction. Aleo instructions serve as the intermediate representation of Aleo programs, facilitating fine-grained circuit design and compatibility with high-level languages. Combined with snarkVM, a versatile toolchain for Aleo development, they enable developers to build privacy-focused applications on the Aleo blockchain efficiently.

Why Aleo Instructions? Before we dive into the technical details, let's understand why Aleo instructions are essential. Unlike traditional blockchains that rely solely on high-level smart contract languages, Aleo's approach allows developers to create programs at a lower level, optimizing for privacy and efficiency. By leveraging Aleo instructions, developers gain more control over the behavior of their programs and can achieve higher levels of privacy.

Installation. Let's kick things off by setting up snarkVM. Ensure you have Rust installed, then proceed with the following commands to install snarkVM:

git clone https://github.com/AleoHQ/snarkvm.git cd snarkvm cargo install --path . --force

Hello Aleo Instructions. Now that we have snarkVM installed, let's develop our first Aleo instructions program: "Hello Aleo."

// hello.aleo

program hello { // Function to print "Hello, Aleo!" public fn main() { print("Hello, Aleo!"); } }

Understanding Aleo Instructions. Aleo instructions resemble an assembly-like programming language. They provide low-level control over the behavior of programs, allowing developers to optimize for privacy, efficiency, and security. By mastering Aleo instructions, developers can create complex applications tailored to their specific needs.

Command Line Interface documentation. snarkVM provides a suite of commands to streamline Aleo development. Let's explore essential commands like snarkvm new, snarkvm run, and more:

To create a new package, run:

snarkvm new {$NAME}

Valid package names are snake_case: lowercase letters and numbers separated by underscore. This command will create a new directory with the given package name. The new package will have a directory structure as follows:

package-name/
├── program.json # Your program manifest
├── README.md # Your program description
└── main.leo # Your program file

To run your Aleo program function run:

snarkvm run {$FUNCTION} {$INPUTS}

// Example
snarkvm run hello 2u32 3u32

To run your Aleo program function in offline mode run:

snarkvm run {$FUNCTION} {$INPUTS} --offline

To run your Aleo program function to a specified endpoint run:

snarkvm run {$FUNCTION} {$INPUTS} --endpoint {$ENDPOINT}

To execute your Aleo program function run:

snarkvm execute {$FUNCTION} {$INPUTS}

// Example
snarkvm run hello 2u32 3u32

To execute your Aleo program function in offline mode run:

snarkvm execute {$FUNCTION} {$INPUTS} --offline

To execute your Aleo program function to a specified endpoint run:

snarkvm execute {$FUNCTION} {$INPUTS} --endpoint {$ENDPOINT}

To clean the Aleo package build directory run:

To update snarkVM to the latest version run:

snarkvm update

To list the available versions of Aleo run:

snarkvm update --list

To update snarkVM and suppress outputs to terminal run:

snarkvm update --quiet
