Chain Database Snapshot

Darwinia provides node database snapshots for node maintainers, facilitating a quick start for a node without syncing from the genesis block. The archive node snapshot contains the state of the blockchain at a certain block height, allowing the node to start from that point instead of starting from the genesis block. Node maintainers can download the latest archive node snapshot and start a node instantly, significantly reducing the block syncing time from several days to about 30 minutes.

Available Snapshots

Darwinia2 Network: https://snapshots.darwinia.network

Crab2 Network: https://snapshots.crab.network

The number in the file names indicates the block height of the snapshot. For example, the block number of snapshot darwinia2-883924.tar.zst is 883924.

Usage

Install zstd

shell
# Debian, Ubuntu
apt install zstd
# CentOS, Rad Hat
dnf install zstd
# Arch Linux
pacman -S zstd

Download the snapshot archive and extract

Copy the archive URL to the specific snapshot(Latest Snapshot recommended) and run the following command:

shell
wget -c https://snapshots.darwinia.network/darwinia-xxxx.tar.zst
mkdir -p /path/to/chain-dir
tar xv --zstd -f darwinia2-xxxx.tar.zst -C /path/to/chain-dir

It's worth noting that /path/to/chain-dir depends on two factors:

the node CLI option -base.

the chain name.

For example, assume with --base data, the chain dirs for the networks are:

Darwinia Network: data/chains/darwinia2

Crab Network: data/chains/crab2

Start node

Once you have placed these extracted database files in the correct locations, then you can start your node either a full node or an archive node, by following the other tutorials.
