This guide explains how to download and use our pre-built node snapshot to stand up a mainnet Blast node as quickly as possible. The snapshot, available at https://pub-0509dd39c2df4aeda4e82ff320667d97.r2.dev/<version.tgz> is updated weekly to minimize required sync times.
Testnet snapshots are not available at this time.

Usage Instructions

1

Navigate to Geth Data Directory

First, navigate to your geth data directory where the blockchain data is stored:
cd <geth data directory>
2

Download the Snapshot

You can download the latest snapshot using wget:
wget -O geth.tgz https://pub-0509dd39c2df4aeda4e82ff320667d97.r2.dev/$(curl https://pub-0509dd39c2df4aeda4e82ff320667d97.r2.dev/LATEST)
Alternatively, for faster download speeds, especially for large files like this snapshot (1.5 TB+), consider using aria2c:
aria2c --file-allocation=none -c -x 10 -s 10 -o geth.tgz https://pub-0509dd39c2df4aeda4e82ff320667d97.r2.dev/$(curl https://pub-0509dd39c2df4aeda4e82ff320667d97.r2.dev/LATEST)

About aria2c

aria2c is a lightweight command-line download utility that can significantly speed up large file downloads by splitting the file into multiple segments and downloading them concurrently.Here’s what the options example above do:
  • --file-allocation=none: Disables file pre-allocation, allowing the download to start immediately.
  • -c: Resumes an incomplete download.
  • -x 10: Sets the maximum number of connections per server to 10.
  • -s 10: Splits the file into 10 segments, downloading them simultaneously.
  • -o geth.tgz: Renames the output file which may otherwise vary based on the latest version.
3

Extract the Snapshot

Once the download is complete, unarchive the snapshot to your geth data directory:
tar -xvzf geth.tgz
This command extracts the files to the appropriate directory for your node to use.
4
Finally, (assuming you’re using the Docker Compose setup), start your node containers:
cd ..
docker compose up -d
Your node should now be up and running using the latest blockchain snapshot.
