Snapshot Guide
WARNING
First, you need to setup your node up with the pre-requisites as per the node setup guide
Before you start your node for fxcore to sync, follow the steps below to use snapshot
If your fxcore node has already started, please stop it and then follow the steps below to use the snapshot
Once unpacking is complete, you can start the fxcore service again
Types of Pundi AIFX Snapshots
A pruned-snapshot, which contains only the most recent day's data
Only data for the most recent day, no earlier data
Small amount of data and footprint
A full-node snapshot, which contains all the transaction data
Contains all transaction data, as well as current state data
Large amount of data and footprint
The greater the blockchain data, the more evident the reduction is syncing time will be. If the current state of the blockchain will take about 2 days to sync, this method of syncing will reduce the time to sync by at least 12 hours.
Available snapshots
Snapshots are performed based on its type as per below, keeping a record of recent snapshot for as per below. If the date on the file is not yet updated and more than a week has lapsed since the last snapshot, you may replace the date in the file name to get the latest snapshot. If the date or day of the month are single digits, make sure to prepend a 0 in front of the single digit number. Date format will be in YYYY-MM-DD.
Pruned-shapshot (light node)
Snapshot frequency: once a day (10am GMT +8)
Snapshot record keeping: 3 most recent
Full-node snapshot (full node)
Snapshot frequency: every Tuesday (10pm GMT +8)
Snapshot record keeping: 1 most recent
Downloading the Snapshots
Download the snapshot to your VM. To download the snapshot tar file to your VM you can run the following command:
This will download the snapshot of fxcore full-node data. Since it's full-node, downloading the snapshot and unpacking the file will take some time.
MD5 checksum for downloaded file
Checksums are often used to verify data integrity but are not relied upon to verify data authenticity, below are example of the md5sum command to check whether the file is downloaded correctly using
compare the md5 hash against https://fx-mainnet.s3.amazonaws.com/fxcore-pruned-snapshot-mainnet-2025-06-06.tar.gz.md5
Extracting the Snapshots
Now, to unpack the tar file in the fxcore Data directory run the following command:
