Installation Guide

Follow these steps to sync your node from the latest snapshot.

1

Download Snapshot

Download the snapshot archive with aria2c for fast multi-connection transfer.

Install dependencies (if needed)

$
sudo apt-get install -y aria2 lz4

Download

$
SNAPSHOT_URL="https://snapshot.kalia.network/snapshots/casper/casper-mainnet-9165112.tar.lz4" && SNAPSHOT_FILE=$(basename "$SNAPSHOT_URL") && aria2c -x 16 -s 16 -k 1M "$SNAPSHOT_URL" -d $HOME
2

Stop Services & Clean Storage

Stop the node and sidecar, then remove the existing chain data.

$
sudo systemctl stop casper-node-launcher casper-sidecar

Remove old chain data

$
sudo rm -rf /var/lib/casper/casper-node
3

Extract Snapshot

Extract the archive into the Casper data directory and fix ownership.

$
lz4 -d -c $HOME/$SNAPSHOT_FILE | sudo tar -xS -C /var/lib/casper
4

Update Trusted Hash

The trusted hash embedded in the snapshot is stale. Fetch the latest block hash from the network and update config.toml.

Fetch latest block hash

$
BLOCK_HASH=$(casper-client get-block --node-address https://node.mainnet.casper.network/rpc | jq -r '.result.block_with_signatures.block.Version2.hash' | tr -d '\n')

Write to config.toml

$
sudo sed -i "/trusted_hash =/c\trusted_hash = '${BLOCK_HASH}'" /etc/casper/2_2_2/config.toml
5

Start Services & Verify

Start the node launcher and sidecar, then follow the logs to confirm sync.

$
sudo systemctl start casper-node-launcher casper-sidecar

Follow logs

$
/etc/casper/node_util.py watch
6

Cleanup

Remove the downloaded snapshot archive to free up disk space.

$
rm -f $HOME/$SNAPSHOT_FILE
