Snapshot Tool

Introduction​

The Conflux Blockchain Data Snapshot Tool (aka Archive-Tool) is designed to help users quickly set up a Conflux node from a snapshot. This tool provides the download links, and by default, it downloads the DB snapshot data of the current day. The Snapshot tool can help save weeks of time required to download and sync all the blockchain data at the moment of running a node. Using this tool is optional, but highly recommended. The tool supports resuming downloads from breakpoints using the curl command. If an error occurs during the process, users are advised to follow the script prompts.

Prerequisites​

Ensure you have curl installed on your system. If not, you can download and install it from here.

Unzip Snapshot Data​

Then, you’ll need to unzip the file, and copy (or move) its content into your node folder, usually named "run".

For example:

tar -xvzf conflux-fullnode-db-snapshot-2023-09-20.tgz -C ./run

The snapshot data also includes the pos_config folder, and the Conflux client release will also include the pos_config folder. You can use either one.

Then you can start your node.
