Downloading the blockchain

Bootstrap the blockchain database using Mithril snapshots or csnapshots.io.

Syncing from genesis can take days. Use a snapshot service to bootstrap the database in minutes instead.

Mithril (Mainnet)

Auto-detects architecture and fetches the latest Mithril release:

cd /home/cardano/cnode

rm -rf db

ARCH=$(uname -m)
if [ "$ARCH" = "x86_64" ]; then MARCH=x64; elif [ "$ARCH" = "aarch64" ]; then MARCH=arm64; else echo "Unsupported arch: $ARCH"; exit 1; fi

MITHRIL_VERSION=$(curl -s https://api.github.com/repos/input-output-hk/mithril/releases/latest | jq -r '.tag_name')
echo "Installing mithril-client ${MITHRIL_VERSION} (${MARCH})"

curl -L -o mithril.tar.gz \
  "https://github.com/input-output-hk/mithril/releases/download/${MITHRIL_VERSION}/mithril-${MITHRIL_VERSION}-linux-${MARCH}.tar.gz"
tar -xzf mithril.tar.gz
install -m 755 mithril-client $HOME/.local/bin/
rm -f mithril.tar.gz mithril-client mithril-signer mithril-aggregator mithril-relay

mithril-client cardano-db download --include-ancillary latest

--include-ancillary downloads the last ledger state and immutable file, significantly speeding up initial sync. The ancillary data is verified against a separate Ed25519 key.
