Darwinia and Crab Network Database Snapshot

Darwinia provides the node database snapshots for node maintainers. It enables maintainers to download the latest snapshot, unarchive, and start a node instantly without syncing from block zero.

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

1. Install zstd:

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

2. Download the snapshot archive and extract:

   Copy the snapshot archive URL from https://snapshots.darwinia.network or https://snapshots.crab.network. Always choosing the latest snapshot with the highest block number is strongly recommended.

   wget -c https://snapshots.darwinia.network/darwinia-xxxx.tar.zst # the snapshot URL
   tar xv --zstd -f darwinia2-xxxx.tar.zst -C /path/to/chain-dir # Or tar xv -I 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 networks are:

   • Darwinia Network: /data/chains/darwinia2
   • Crab Network: /data/chains/crab2
