Kusama is Polkadot’s canary network – a proving ground for runtime upgrades and governance experiments before they are deployed on Polkadot. Our Kusama snapshots help you quickly sync a Kusama node for development, testing, or running a validator.
These are pruned snapshots containing recent blockchain state. They are updated continuously – our servers always keep the last 2 snapshots available.
