Step 1: Run an Octez node

To use the Octez suite with Ghostnet, you need a recent build of the Octez binaries. You can build the Octez suite from the source code or install prebuilt binaries as described at https://tezos.gitlab.io/introduction/howtoget.html.

note

If you already have an Octez node and baker running with a delegated account, you can skip to Step 3: Run an Octez DAL node.

The first step is to configure a Tezos node with the octez-node program:

  1. Install the Octez suite of programs, including octez-client, octez-node, and octez-dal-node as described in Installing Octez in the Octez documentation. If you build from source, you can use the latest_branch branch to work with Ghostnet.

  2. Initialize the Octez node for Ghostnet, such as in this example:

    octez-node config init --network ghostnet

  3. Speed up the process of initializing the node by loading a snapshot:

    1. Download a rolling snapshot of Ghostnet from https://snapshot.tzinit.org based on the instructions on that site. For example, the command to download the snapshot from the EU servers might look like this:

      wget -O snapshot_file https://snapshots.eu.tzinit.org/ghostnet/rolling

    2. Load the snapshot in the node by running this command:

      octez-node snapshot import snapshot_file

  4. Start the node:

    octez-node run --rpc-addr 127.0.0.1:8732 --log-output="$HOME/octez-node.log"

  5. Ensure that the node runs persistently. Look up how to run programs persistently in the documentation for your operating system. You can also refer to Run a persistent baking node on opentezos.com.

  6. Optional: When the node has bootstrapped and caught up with the current head block, you can delete the snapshot file to save space.

At first launch, the node generates a fresh identity file used to identify itself on the network. Then it bootstraps the chain, which takes a variable amount of time depending on how many blocks need to be loaded.

In the meantime, you can continue the baking infrastructure while the node is bootstrapping. Continue to Step 2: Set up a baker account.
