sudo apt update && sudo apt upgrade --yes && \
sudo apt install git build-essential ufw curl jq snapd screen ncdu nano fuse ufw --yes

1. Install go using snap.

sudo snap install go --classic && \
echo 'export GOPATH="$HOME/go"' >> ~/.profile && \
echo 'export GOBIN="$GOPATH/bin"' >> ~/.profile && \
echo 'export PATH="$GOBIN:$PATH"' >> ~/.profile && \
source ~/.profile && \
go version

1. Download the binary.

git clone https://github.com/gravity-bridge/gravity-bridge
cd gravity-bridge/module
git checkout v1.12.0
make install
gravity version

1. Initialize your node.

gravity init <node_name> --chain-id gravity-bridge-3

1. Download genesis.

curl https://raw.githubusercontent.com/Gravity-Bridge/gravity-docs/main/genesis.json > $HOME/.gravity/config/genesis.json

1. Add seeds and persistent peers to config.toml.

SEEDS="[email protected]:14256,[email protected]:10556"
PEERS="[email protected]:26856, [email protected]:26656, [email protected]:26656, [email protected]:42656"
sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.gravity/config/config.toml

1. Set up minimum gas price.

sed -i 's|^minimum-gas-prices *=.*|minimum-gas-prices = "0ugraviton"|g' $HOME/.gravity/config/app.toml

1. Set up pruning (optional).

pruning="custom"
pruning_keep_recent="100"
pruning_keep_every="0"
pruning_interval="10"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.gravity/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.gravity/config/app.toml
sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" $HOME/.gravity/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.gravity/config/app.toml

1. Create service file.

sudo tee /etc/systemd/system/gravity-node.service > /dev/null <<EOF
[Unit]
Description=Gravity blockchain node
Requires=network.target

[Service]
Type=simple
TimeoutStartSec=10s
Restart=always
RestartSec=10
ExecStart=$(which gravity) start
LimitNOFILE=500000
LimitNPROC=500000
Environment="HOME=/root"

[Install]
WantedBy=default.target
EOF

1. Enable and start service.

systemctl daemon-reload
systemctl enable gravity-node
systemctl restart gravity-node
journalctl -u gravity-node -f -o cat
