Node Snapshot
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://mainnet-snapshots.blast.io/geth.tgz is updated weekly to minimize required sync times.
Testnet snapshots are not available at this time.
Usage Instructions
Navigate to Geth Data Directory
First, navigate to your geth data directory where the blockchain data is stored:
Download the Snapshot
You can download the latest snapshot using wget:
Alternatively, for faster download speeds, especially for large files like this snapshot (1.5 TB+), consider using aria2c:
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.
Extract the Snapshot
Once the download is complete, unarchive the snapshot to your geth data directory:
This command extracts the files to the appropriate directory for your node to use.
Finally, (assuming you’re using the Docker Compose setup), start your node containers:
Your node should now be up and running using the latest blockchain snapshot.
