<p>This repository is home to the <code>snops</code> (snarkOS operations) ecosystem, and
<code>snarkos-aot</code>, a crate for performing ahead-of-time ledger actions, transaction
authorizations, and various tools for helping with developing Aleo programs.</p>
<p>snops is a suite of tools that can be used to maintain <a href="https://aleo.org/">Aleo</a>
network environments. The environments are defined in a manner similar to
infrastructure-as-code, which means you can create repeatable infrastructure
using the environment schema.</p>
<p>This can be used to create devnets, simulate events on the network like outages
and attacks, and guarantee metrics.</p>
<p>To learn more about <code>snops</code> we recommend checking out the mdbook <a href="https://monadicus.github.io/snarkops/">here</a>.</p>
<h2 id="snops-quickstart"><a class="header" href="#snops-quickstart">Snops Quickstart</a></h2>
<h3 id="easy-setup"><a class="header" href="#easy-setup">Easy Setup</a></h3>
<p><code>snops</code> contains several components that can be compiled separately. The <code>release-big</code> build profile allows for faster near-release profile performance with faster near-debug profile build times.</p>
<ol>
<li>
<p>Install <a href="https://www.rust-lang.org/">rust</a></p>
</li>
<li>
<p>Clone the repo</p>
</li>
<li>
<p>Start + build the control plane: <code>./scripts/control_plane.sh</code></p>
<p>The controlplane is the webserver that communicates to agents how to
run snarkOS, or what transactions to execute.</p>
</li>
<li>
<p>In another terminal, build the cli: <code>cargo install --path ./crates/snops-cli</code></p>
<p>The cli is used to interact with the controlplane and manage environments.
It provides JSON based output. We recommend pairing our cli with <a href="https://jqlang.github.io/jq/"><code>jq</code></a> when leveraging other scripts and tools</p>
</li>
<li>
<p>Build the agent: <code>cargo build --profile release-big -p snops-agent</code></p>
<p>The agent is a lightweight service that starts up <code>snarkos-aot</code> which
automatically configures snarkos nodes, or executes transactions.</p>
</li>
<li>
<p>Build <code>snarkos-aot</code> (for running nodes): <code>cargo build --profile release-big -p snarkos-aot</code></p>
<p><code>snarkos-aot</code> is an alternative snarkOS CLI providing more developer-oriented
features as well as tooling for distributed transaction generation and execution.</p>
</li>
<li>
<p>In separate terminals, start up some agents with the following commands:</p>
<pre><code class="language-sh">./script/agent.sh 0
./script/agent.sh 1
./script/agent.sh 2
./script/agent.sh 3
</code></pre>
<p>Each of these can be dynamically configured as snarkos nodes. The default
agent configuration should connect to a locally operated controlplane.</p>
</li>
</ol>
<h3 id="local-isonets"><a class="header" href="#local-isonets">Local Isonets</a></h3>
<p>This example requires 4 agents and the control plane to be running.</p>
<ol>
<li>Start the environment: <code>snops-cli env prepare specs/test-4-validators.yaml</code></li>
<li>Check the current network height: <code>snops-cli env height</code></li>
<li>Look at the latest block: <code>snops-cli env block</code></li>
<li>Look at the genesis block: <code>snops-cli env block 0</code></li>
<li>Stop the environment: <code>snops-cli env clean</code></li>
</ol>
<h3 id="isonet-transfers"><a class="header" href="#isonet-transfers">Isonet Transfers</a></h3>
<p>Using the setup for a <a href="#local-isonets">Local Isonet</a>, executing Aleo programs has never
been more convenient. Snops aliases locally generated keys automatically from configuration and
reduces the need to keep track of individual key files.</p>
<ol>
<li>
<p>Start an environment (see previous example)</p>
</li>
<li>
<p>Start a compute agent: <code>./scripts/agent_compute.sh 0</code></p>
<p>Compute agents are able to distribute the execution of transactions,
offloading the compute task to different servers.</p>
</li>
<li>
<p>Check the balance of committee member 1's key:</p>
<pre><code class="language-sh">$ snops-cli env balance committee.1
10000000000000
</code></pre>
</li>
<li>
<p>Transfer 1 credit to committee member 1 from committee member 0 (look on snarkos this command would require MANY more flags):</p>
<pre><code class="language-sh">snops-cli env action execute transfer_public committee.1 1_000_000u64
</code></pre>
</li>
<li>
<p>Check the balance of committee member 1's key (it may take a few seconds for the block to advance):</p>
<pre><code class="language-sh">snops-cli env balance committee.1
10000001000000
</code></pre>
</li>
</ol>
<h3 id="isonet-program-deployments"><a class="header" href="#isonet-program-deployments">Isonet Program Deployments</a></h3>
<p>Deploying and executing Aleo programs on your isonets is easiest with snops. You do not need any extra json files or tooling, only a standalone <code>.aleo</code> file.</p>
<ol>
<li>
<p>Use the same setup as before</p>
</li>
<li>
<p>Create a file <code>mapping_example.aleo</code> with the following contents:</p>
<pre><code class="language-js">program mapping_example.aleo;
mapping mymapping:
key as u8.public;
value as u8.public;
function store:
input r0 as u8.public;
input r1 as u8.public;
async store r0 r1 into r2;
output r2 as mapping_example.aleo/store.future;
finalize store:
input r0 as u8.public;
input r1 as u8.public;
set r1 into mymapping[r0];
</code></pre>
</li>
<li>
<p>Deploy the program: <code>snops-cli env action deploy ./mapping_example.aleo</code></p>
</li>
<li>
<p>Verify the program is on the chain: <code>snops-cli env program mapping_example.aleo</code></p>
</li>
<li>
<p>Check an example mapping</p>
<pre><code class="language-sh">$ snops-cli env mapping mapping_example.aleo mymapping 0u8
{
"value": null
}
</code></pre>
</li>
<li>
<p>Execute the <code>store</code> function on-chain: <code>snops-cli env action execute mapping_example.aleo/store 0u8 5u8</code></p>
</li>
<li>
<p>Check the example mapping for its updated value</p>
<pre><code class="language-sh">$ snops-cli env mapping mapping_example.aleo mymapping 0u8
{
"value": "5u8"
}
</code></pre>
</li>
</ol>
<h2 id="snarkos-aot-quickstart"><a class="header" href="#snarkos-aot-quickstart">SnarkOS-aot Quickstart</a></h2>
<p><code>snarkos-aot</code> provides various CLI tools to help with developing and executing
Aleo programs as well as interact with snarkOS ledgers.</p>
<p>Build <code>snarkos-aot</code> with: <code>cargo install --profile release-big -p snarkos-aot</code>.
The compiled binary can be found in <code>target/release-big/snarkos-aot</code>.</p>
<p>Use the <code>NETWORK</code> environment variable to specify <code>mainnet</code> (default),
<code>testnet</code>, or <code>canary</code>.</p>
<h3 id="transaction-authorizations"><a class="header" href="#transaction-authorizations">Transaction Authorizations</a></h3>
<p>Typically when executing snarkOS transactions you specify the program and inputs
and receive a proof. Behind the scenes, snarkVM is using a private key to
"authorize" the proof for the program execution, and "authorize" the proof for
the fee.</p>
<p>Creating authorizations is much quicker than executing the transaction, and the
process can be done airgapped or even on web clients.</p>
<pre><code class="language-sh"># Create an authorization for a executing transfer_public to the "example.aleo" program for 1 microcredit
NETWORK=testnet snarkos-aot auth program --private-key <PK> credits.aleo/transfer_public example.aleo 1u64 > auth.json
# The same as above but with a different private key
NETWORK=testnet snarkos-aot auth program --private-key <PK> --fee-private-key <PK> credits.aleo/transfer_public example.aleo 1u64 > auth.json
# Create an authorization for deploying a program (from my_program.aleo)
NETWORK=testnet snarkos-aot auth deploy --private-key <PK> my_program.aleo
# Determine the cost to deploy a program (from stdin)
cat my_program.aleo | NETWORK=testnet snarkos-aot auth deploy --private-key <PK> - | NETWORK=testnet snarkos-aot auth cost -
# Execute an authorization from auth.json without broadcasting it (the - means stdin)
cat auth.json | NETWORK=testnet snarkos-aot auth execute - --query https://api.explorer.aleo.org/v1
# Get the cost of an authorization (program or deployment) without executing the transaction
cat auth.json | NETWORK=testnet snarkos-aot auth cost -
# Derive the transaction id from an authorization without executing it
cat auth.json | NETWORK=testnet snarkos-aot auth id -

<p><code>snarkos-aot</code> contains various tools to programmatically interact with aleo program.</p>
<p>If you don't have any Aleo programs you can download a program (<code>credits.aleo</code>)
from Aleo Explorer with the following commands. You can find a list of
programs on <a href="https://explorer.aleo.org/programs">Aleo Explorer's Programs List</a>.</p>
<pre><code class="language-sh">NETWORK=testnet
PROGRAM=credits.aleo
# Download a program, then un-jsonify it
curl https://api.explorer.aleo.org/v1/$NETWORK/program/$PROGRAM | jq -r > $PROGRAM
</code></pre>
<p>Below are some <code>snarkos-aot</code> commands for interacting with programs.</p>
<pre><code class="language-sh"># Get a program's id from a text file
$ snarkos-aot program id ./credits.aleo
credits.aleo
# Calculate the cost of deploying a program
$ snarkos-aot program cost ./example.aleo
2568400
# Get a list of imports for a program (output in a json format with --json)
$ snarkos-aot program imports ./staking_v1.aleo --json
["credits.aleo"]
# Get a list of functions (and respective inputs/outputs) for a program (jq for formatting)
$ snarkos-aot program functions ./domainnames.aleo --json | jq
{
"validate_name": {
"inputs": [
"[u128; 4u32].private"
],
"outputs": [
"boolean.private"
]
}
}
