snarkOS is a decentralized operating system for private applications. It forms the backbone of Aleo and enables applications to verify and store state in a publicly verifiable manner.
The following are minimum requirements to run an Aleo node:
- CPU: 16-cores (32-cores preferred)
- RAM: 16GB of memory (32GB preferred)
- Storage: 128GB of disk space
- Network: 50 Mbps of upload and download bandwidth
Please note to run an Aleo mining node that is competitive, the machine will require more than these requirements.
Before beginning, please ensure your machine has Rust v1.56+ installed. Instructions to install Rust can be found here.
Start by cloning the snarkOS 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:
./testnet2_ubuntu.sh
Start by following the instructions in the Build Guide.
Next, to start a client node, from the snarkOS directory, run:
./run-client.sh
Start by following the instructions in the Build Guide.
Next, to generate an Aleo miner address, run:
snarkos experimental new_account
or from the snarkOS directory, run:
cargo run --release -- experimental new_account
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
View Key AViewKey1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx <-- Save Me
Address aleo1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx <-- Use Me For The Next Step
Next, to start a mining node, from the snarkOS directory, run:
./run-miner.sh
When prompted, enter your Aleo miner address:
Enter your Aleo miner address:
aleo1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
After the mining node has booted up, a periodic report is provided with the status of mined blocks:
INFO Mining Report (confirmed_blocks = 1, pending_blocks = 5, miner_address = aleo1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx)
This report can also be queried after the mining node has already ran,
by running cargo run --release -- miner stats aleo1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
in the snarkOS directory, or snarkos miner stats aleo1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.
- Ensure your machine has
Rust v1.56+installed. Instructions to install Rust can be found here. - If large errors appear during compilation, try running
cargo clean. - Ensure snarkOS is started using
./run-client.shor./run-miner.sh.
- Ensure ports
4132/tcpand3032/tcpare open on your router and OS firewall. - Ensure snarkOS is started using
./run-client.shor./run-miner.sh.
- Before running the command above (
snarkos experimental new_account) trysource ~/.bashrc - Also double check the spelling of
snarkos. Note the directory is/snarkOS, the command issnarkos
- Yes. Just spin up multiple instances of snarkOS across multiple machines (not the same machine) and input the same miner address. At the moment, Aleo does not integrate with any other mining pool protocols (like stratum). But if anyone wants to implement, please apply for a grant!
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:

--norpc If the flag is set, the node will not initialize the RPC server
-V, --version Prints version information
OPTIONS:
--config <config-file> Specify the config file path
--connect <connect> Specify the IP address and port of a peer to connect to
--dev <dev> Enables development mode, specify a unique ID for the local node
--miner <miner> Specify this as a mining node, with the given miner address
--network <network> Specify the network of this node [default: 2]
--node <node> Specify the IP address and port for the node server [default: 0.0.0.0:4132]
--rpc <rpc> Specify the IP address and port for the RPC server [default: 0.0.0.0:3032]
--password <rpc-password> Specify the password for the RPC server [default: pass]
--username <rpc-username> Specify the username for the RPC server [default: root]
--verbosity <verbosity> Specify the verbosity of the node [options: 0, 1, 2, 3] [default: 2]
SUBCOMMANDS:
clean Removes the ledger files from storage
experimental Experimental features
help Prints this message or the help of the given subcommand(s)
miner Miner commands and settings
update Updates snarkOS to the latest version
In one terminal, start the first node by running:
cargo run --release -- --dev 1 --node 0.0.0.0:4135 --rpc 0.0.0.0:3035 --miner aleo1d5hg2z3ma00382pngntdp68e74zv54jdxy249qhaujhks9c72yrs33ddah
After the first node starts, in a second terminal, run:
cargo run --release -- --dev 2
