Full state sync from archive snapshot

If a node needs a full state history but wants to synchronize faster, it can start the chain from a history snapshot, (updated daily).

Find the most recent state snapshot on the list https://archive-testnet.empe.io/full_backup/

Available snapshots:

../
empe-chain-1_2025-03-17.tar                        17-Mar-2025 04:39    756G
empe-chain-1_2025-03-18.tar                        18-Mar-2025 04:29    762G

The latest snapshot is always preferable as it contains the most up-to-date state.

Download and install the full snapshot

# Set the snapshot file name
ARCHIVE=empe-chain-1_2025-03-18.tar

# Download the snapshot
curl -O https://archive-testnet.empe.io/full_backup/$ARCHIVE

# Extract the snapshot to your data directory
tar -xvf $ARCHIVE -C ~/.empe-chain/data

# Clean up the downloaded archive
rm $ARCHIVE

Download and install address book

For faster peer discovery, you can also download the latest address book:

# Download the latest address book
wget -O $HOME/.empe-chain/config/addrbook.json "https://raw.githubusercontent.com/111STAVR111/props/main/Empeiria/addrbook.json"

This will help your node connect to peers more quickly and reduce the time needed for initial network discovery.

Start your node

After installing the snapshot and address book, you can start your chain using cosmovisor.

Alternative option

If you need a smaller snapshot size, consider using a lite snapshot instead: https://archive-testnet.empe.io/lite_backup/
