moonsnap-downloadoor

This is a tool for snappy bootstrapping of new full and archive nodes. It saves between 66% and 99.2% of the time required to sync a new node from scratch.

Usage

1. Get a SNAP_KEY from https://warpcast.com/crebsy/0xc021a0cf
2. Compile or download the binary from https://dl.moonsnap.xyz/moonsnap
3. Download the snap to your infra with max speed 🚀
4. Start your node and let it sync only a small diff to reach the head of the chain

Configuration

Run with pre-built binary

There's a pre-built binary which can be used directly:

curl https://dl.moonsnap.xyz/moonsnap -o moonsnap
chmod +x moonsnap
./moonsnap <YOUR_SNAP_KEY> <YOUR_OUT_DIR>

Run with docker

You can also use our pre-built docker image: ghcr.io/crebsy/moonsnap-downloadoor To start, set the following env variables:

docker run -e MOONSNAP_SNAP_KEY=<YOUR_SNAP_KEY> -e MOONSNAP_OUT_DIR=<YOUR_OUT_DIR> -d ghcr.io/crebsy/moonsnap-downloadoor

Build locally

You can also build the binary yourself:

git clone https://github.com/crebsy/moonsnap-downloadoor.git
cd moonsnap-downloadoor
go build -o moonsnap
./moonsnap <YOUR_SNAP_KEY> <YOUR_OUT_DIR>
