Prerequisite

0G Storage and DA services interact with on-chain contracts for blob root confirmation and PoRA mining.

This step is performed after your validator has been installed and created.

check zgs version

$HOME/0g-storage-node/target/release/zgs_node --version

Set vars (For SSD disks). you found more from official docs

export ZGS_LOG_DIR="$HOME/0g-storage-node/run/log"
export ZGS_LOG_CONFIG_FILE="$HOME/0g-storage-node/run/log_config"
export LOG_CONTRACT_ADDRESS="0xbD2C3F0E65eDF5582141C35969d66e34629cC768"
export MINE_CONTRACT="0x6815F41019255e00D6F34aAB8397a6Af5b6D806f"

export ZGS_LOG_SYNC_BLOCK=595059

Extract Ethereum private key from your validator (we will need this key in the next step)

0gchaind keys unsafe-export-eth-key $WALLET_NAME

After entering the next command, a field will appear in which you should enter the key you received in the previous step. Note that the text you enter will not be displayed.

read -sp "Enter your extracted private key: " PRIVATE_KEY && echo

Set the miner_key in the config.toml file

sed -i 's|^miner_key = ""|miner_key = "'"$PRIVATE_KEY"'"|' $HOME/0g-storage-node/run/config.toml

Set var the Storage Node IP address

ZGS_IP=$(wget -qO- eth0.me)

Edit the storage node config

sed -i '
s|# network_dir = "network"|network_dir = "network"|g
s|# network_enr_tcp_port = 1234|network_enr_tcp_port = 1234|g

Update boot nodes addresses

sed -i 's|^network_boot_nodes = .*|network_boot_nodes = ["/ip4/47.251.117.133/udp/1234/p2p/16Uiu2HAmTVDGNhkHD98zDnJxQWu3i1FL1aFYeh9wiQTNu4pDCgps","/ip4/47.76.61.226/udp/1234/p2p/16Uiu2HAm2k6ua2mGgvZ8rTMV8GhpW71aVzkQWy7D37TTDuLCpgmX"]|g' ~/0g-storage-node/run/config.toml

Set blockchain_rpc_endpoint from your validator's (json-rpc endpoint). To connect your storage node to the validator.

You can use the json-rpc of your validator (which you can see in the $HOME/.0gchain/config/app.toml file) or use any available from the community.

You should also have the indexer enabled in the validator config: sed -i -e "s/^indexer *=.*/indexer = \"kv"/" $HOME/.0gchain/config/config.toml

Official 0g rpc endpoint:

BLOCKCHAIN_RPC_ENDPOINT="https://evmrpc-testnet.0g.ai"
sed -i 's|^blockchain_rpc_endpoint = ".*"|blockchain_rpc_endpoint = "'"$BLOCKCHAIN_RPC_ENDPOINT"'"|' $HOME/0g-storage-node/run/config.toml
echo "export BLOCKCHAIN_RPC_ENDPOINT=\"$BLOCKCHAIN_RPC_ENDPOINT\"" >> ~/.bash_profile

Create a service file

sudo tee /etc/systemd/system/zgs.service > /dev/null <<EOF

Useful commands ⚙️

Stop the storage node

sudo systemctl stop zgs

Check list of logs

ls ~/0g-storage-node/run/log/

Check logs on a specific date. For example:

tail -f ~/0g-storage-node/run/log/zgs.log.2024-06-04

Check the latest logs file

tail -f ~/0g-storage-node/run/log/zgs.log.$(TZ=UTC date +%Y-%m-%d)

Check sync status

curl -X POST http://localhost:5678 -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"zgs_getStatus","params":[],"id":1}'  | jq

Delete node 🗑️

sudo systemctl stop zgs && sudo systemctl disable zgs
sudo rm -rf /etc/systemd/system/zgs.service
sudo rm $(which zgs)
sudo rm -rf $HOME/0g-storage-node
