DA Node

﻿
While there are various approaches to running a DA (Data Availability) node, this guide outlines our recommended method and the necessary hardware specifications. DA Nodes perform the core functions of verifying, signing, and storing encoded blob data. It's important to note that your DA signer needs to operate a DA node to verify encoded blob data, sign it, and store it for future farming and rewards. Currently, in order to run a DA Node on Testnet, users must stake 30 A0GI tokens.

 2. Go installation
⌨️
cd $HOME && \
ver="1.23.3" && \
wget "https://golang.org/dl/go$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 && \

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
﻿
 3. Rust installation
⌨️
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env
rustc --version
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env
rustc --version
﻿
4. Clone the 0g-da-node repository from GitHub
⌨️
git clone -b v1.1.3 https://github.com/0glabs/0g-da-node.git
git clone -b v1.1.3 https://github.com/0glabs/0g-da-node.git
﻿
5. Build the project in release mode
⌨️
cd $HOME/0g-da-node
git stash
git fetch --all --tags
git checkout 9a48827 
git submodule update --init
cargo build --release
cd $HOME/0g-da-node
git stash
git fetch --all --tags
git checkout 9a48827 
git submodule update --init
cargo build --release
﻿
6. Download additional parameters needed for the project
⌨️
./dev_support/download_params.sh
./dev_support/download_params.sh
﻿
7. Generate keys using the key-gen binary
⌨️
cargo run --bin key-gen
cargo run --bin key-gen
﻿
You must back up your BLS key.
It cannot be created or confirmed again.
8. Edit the configuration file
⌨️
rm -rf $HOME/0g-da-node/config.toml && curl -o $HOME/0g-da-node/config.toml https://raw.githubusercontent.com/zstake-xyz/test/refs/heads/main/0g_da_config.toml && nano $HOME/0g-da-node/config.toml
rm -rf $HOME/0g-da-node/config.toml && curl -o $HOME/0g-da-node/config.toml https://raw.githubusercontent.com/zstake-xyz/test/refs/heads/main/0g_da_config.toml && nano $HOME/0g-da-node/config.toml
﻿
﻿
9. Create a systemd service file
⌨️
sudo tee /etc/systemd/system/0gda.service > /dev/null <<EOF
[Unit]
Description=0G-DA Node
After=network.target

[Service]
User=$USER
WorkingDirectory=$HOME/0g-da-node
ExecStart=$HOME/0g-da-node/target/release/server --config $HOME/0g-da-node/config.toml
Restart=always
RestartSec=10
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF
sudo tee /etc/systemd/system/0gda.service > /dev/null <<EOF
[Unit]
Description=0G-DA Node
After=network.target

[Service]
User=$USER
WorkingDirectory=$HOME/0g-da-node

Restart=always
RestartSec=10
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF
﻿
10. Start the service immediately
⌨️
sudo systemctl daemon-reload && sudo systemctl enable 0gda && sudo systemctl start 0gda
sudo systemctl daemon-reload && sudo systemctl enable 0gda && sudo systemctl start 0gda
﻿
⌨️ Useful Commands
11. Log Check
⌨️
sudo journalctl -u 0gda -f -o cat 
sudo journalctl -u 0gda -f -o cat 
﻿
Check the DA Log. If it is normal, it looks like this.(PODAS TX : Hit a valid answer)
