BlockDAG Community Snapshots

Hosted by blockdag.builders · Public RPC: rpc.blockdag.builders

What is this?
Pre-validated chain data snapshots so new BlockDAG full-node operators can bootstrap in minutes instead of 24-30 hours of full sync. Updated weekly. SHA256 verified.

Quick Start

# 1. Download latest snapshot (~12 GB compressed)
curl -LO https://snapshots.blockdag.builders/latest.tar.gz

# 2. Verify integrity
EXPECTED=$(curl -s https://snapshots.blockdag.builders/latest.json | jq -r .sha256)
sha256sum latest.tar.gz | awk '{print $1}' | grep -q "^$EXPECTED$" && echo "OK" || echo "FAIL"

# 3. Stop your node
sudo systemctl stop blockdag-node

# 4. Replace data
sudo rm -rf /var/lib/bdagStack/node
sudo tar xzf latest.tar.gz -C /var/lib/bdagStack/
sudo chown -R bdagStack:bdagStack /var/lib/bdagStack/

# 5. Start node — only catch up the gap since snapshot
sudo systemctl start blockdag-node

What you get

Full pre-validated chain state up to snapshot date
Saves ~24-30 hours of initial block download
SHA256 hash for verification
Weekly refresh (Sundays, ~03:00 UTC)

Files

latest.tar.gz — most recent snapshot (symlink)
latest.json — metadata (size, sha256, block height, timestamp)
snapshot-YYYY-MM-DD.tar.gz — dated snapshots (last 2 retained)

Decentralization

This service exists because BlockDAG benefits from multiple independent operators. If you're spinning up your own RPC, mining pool, or full node — this snapshot saves you a day. In exchange: please run a real full node (not a relay), keep it alive, and consider hosting your own snapshots once you're set up.
