☀️ Node Configuration

0gchaind config chain-id zgtendermint_16600-2
0gchaind config keyring-backend os
0gchaind config node tcp://localhost:56657

☀️ Initialize the Node

NOTE: Replace NODE-NAME with your desired node name.

0gchaind init NODE-NAME --chain-id zgtendermint_16600-2

☀️ Update Genesis and Addrbook

rm ~/.0gchain/config/genesis.json
curl -Ls https://github.com/0glabs/0g-chain/releases/download/v0.2.3/genesis.json > $HOME/.0gchain/config/genesis.json

☀️ Add Seed Nodes

PEERS="80fa309afab4a35323018ac70a40a446d3ae9caf@og-testnet-peer.itrocket.net:11656,...(other peers)..."
SEEDS="[email protected]:26656,...(other seeds)..."
sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.0gchain/config/config.toml

☀️ Set Gas and Pruning

sed -i -e "s/^pruning *=.*/pruning = \"custom\"/" $HOME/.0gchain/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"100\"/" $HOME/.0gchain/config/app.toml

sed -i -e "s/prometheus = false/prometheus = true/" $HOME/.0gchain/config/config.toml

☀️ Indexer Configuration

NOTE: If you're setting up a storage node, you might not want to set this to null.

sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.0gchain/config/config.toml

☀️ Set Ports

echo "export G_PORT="56"" >> $HOME/.bash_profile
source $HOME/.bash_profile

sed -i.bak -e "s%:26658%:${G_PORT}658%g; s%:26657%:${G_PORT}657%g; ..." $HOME/.0gchain/config/config.toml

☀️ Snap Installation

🚨🚨🚨 Don’t forget to back up your priv_validator_key.json file located inside the config folder. 🚨🚨🚨

NOTE: If you want to use your own RPC on your storage node you have to use snapshot start from blockheight 0

screen -S 0g

sudo systemctl stop 0gchaind

0gchaind tendermint unsafe-reset-all --home $HOME/.0gchain --keep-addr-book

cp $HOME/.0gchain/data/priv_validator_state.json $HOME/.0gchain/priv_validator_state.json.backup

curl -L https://vps5.josephtran.xyz/0g/0gchain_snapshot.lz4 | sudo lz4 -dc - | sudo tar -xf - -C $HOME/.0gchain

mv $HOME/.0gchain/priv_validator_state.json.backup $HOME/.0gchain/data/priv_validator_state.json

☀️ Start the Node

sudo systemctl daemon-reload
sudo systemctl restart 0gchaind

☀️ View Logs

sudo journalctl -u 0gchaind.service -f --no-hostname -o cat

☀️ Check Blocks

while true; do    local_height=$(0gchaind status | jq -r .sync_info.latest_block_height);    network_height=$(curl -s https://cs-rpc-0g.josephtran.xyz/status | jq -r '.result.sync_info.latest_block_height');   blocks_left=$((network_height - local_height));    echo -e "\033[1;38mYour node height:\033[0m \033[1;34m$local_height\033[0m | \033[1;35mNetwork height:\033[0m \033[1;36m$network_height\033[0m | \033[1;29mBlocks left:\033[0m \033[1;31m$blocks_left\033[0m";    sleep 5;  done
