0G DA Node Setup Guide

This guide will help you set up a DA Node for OG Labs. For official documentation, check here.

Requirements

  • Stake 30 A0GI
  • Memory: 16 GB RAM
  • CPU: 8 Cores
  • Disk: 1TB NVME SSD
  • Bandwidth: 100 Mbps (Download / Upload)

You need to stake 30 A0GI to the validator to run 0G DA Node.

Stake with AstroStake

Not in the Top 200 yet — but we’re building, we’re running, and we’re not stopping.

You can still run a DA Node by staking to my validator.

Every stake moves us closer 🚀

Staking via CLI

1. Download 0g binary

cd $HOME
git clone https://github.com/0glabs/0g-chain.git
cd 0g-chain
git checkout v0.5.3
git submodule update --init
make install
0gchaind version

2. Set-up Wallet

Change WalletName to your real wallet name

To create a new wallet, use the following command. Don’t forget to save the mnemonic

0gchaind keys add WalletName

3. Stake

change WalletName to your real wallet name

and you can change --node https://evmrpc-testnet.0g.ai to your favorite RPC

0gchaind tx staking delegate "0gvaloper1aax7fz4d904m0ul3e9v3lfq7cdzzw3ka8qk3mr" 30000000ua0gi --from "WalletName" --chain-id zgtendermint_16600-2 --gas-adjustment 1.5 --gas auto --gas-prices 0.00252ua0gi  --node https://evmrpc-testnet.0g.ai -y

One-Click Command Install 

bash <(wget -qO- https://astrostake.xyz/0GDA_Node_One_Click.sh)

Manual Install

  1. Install necessary packages
sudo apt-get update && sudo apt-get install clang cmake build-essential pkg-config libssl-dev protobuf-compiler llvm llvm-dev
  1. Install go
cd $HOME && \
ver="1.22.0" && \
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz" && \
sudo rm -rf /usr/local/go && \
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz" && \
rm "go$ver.linux-amd64.tar.gz" && \
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> ~/.bash_profile && \
source ~/.bash_profile && \
go version
  1. Install rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

. "$HOME/.cargo/env"
  1. Clone 0G DA Node
git clone -b v1.1.3 https://github.com/0glabs/0g-da-node.git
  1. Build project
cd $HOME/0g-da-node
git stash
git fetch --all --tags
git checkout v1.1.3
git submodule update --init
cargo build --release
  1. Add Params
./dev_support/download_params.sh
  1. Generate BLS private key

Important!

After generating your BLS Private Key, make sure to save it securely.

  • The key is only displayed once when generated.
  • If you lose it, it cannot be recovered.
  • If you ever need to run your DA Node again or migrate to a new VPS, you must use the same BLS Private Key to maintain your node identity.
  • If the key is lost, you’ll need to generate a new BLS Private Key and register a new wallet, which means starting over with a new node identity.
cargo run --bin key-gen
  1. Edit Config
nano $HOME/0g-da-node/config.toml

Edit Config File

Fill: socket_address signer_bls_private_key signet_eth_private_key miner_eth_private_key

# or if you have dns, fill your dns

Useful Commands

Check Logs

sudo journalctl -u 0gda -f -o cat

Change RPC

bash <(wget -qO- https://astrostake.xyz/change_da_rpc.sh)

Stop and delete node

Critical: Backup Your BLS Key!

Do not lose this key — it is required to run your DA Node.

Location $HOME/0g-da-node/config.toml

Stop

sudo systemctl stop 0gda

Delete

sudo systemctl disable 0gda
sudo rm /etc/systemd/system/0gda.service
rm -rf $HOME/0g-da-node
