Database Snapshots

To decrease sync times, users may opt to download a Juno database snapshot. After downloading a snapshot and starting a Juno node, only recent blocks must be synced.

Run Juno Using Snapshot

1. Download Snapshot

   Fetch a snapshot from one of the provided URLs:

   wget -O juno_mainnet.tar https://juno-snapshots.nethermind.dev/mainnet/juno_mainnet_v0.9.3_519634.tar

2. Prepare Directory

   Ensure you have a directory where you will store the snapshots. We will use $HOME/snapshots.

   mkdir -p $HOME/snapshots

3. Extract Tarball

   Extract the contents of the .tar file:

   tar -xvf juno_mainnet.tar -C $HOME/snapshots

4. Run Juno

   Execute the Docker command to run Juno, ensuring that you're using the correct snapshot path $HOME/snapshots/juno_mainnet:

   docker run -d \
      --name juno \
      -p 6060:6060 \
      -v $HOME/snapshots/juno_mainnet:/var/lib/juno \
      nethermind/juno \
      --http \
      --http-port 6060 \
      --http-host 0.0.0.0 \
      --db-path /var/lib/juno

After following these steps, Juno should be up and running on your machine, utilizing the provided snapshot.
