Validator Node

Running a validator node for the 0G-Galileo-Testnet in the 0G ecosystem means actively participating in the network's security and consensus through the Proof-of-Stake (PoS) mechanism. As a validator, you'll validate transactions, propose new blocks, and earn rewards for your contribution to the network's integrity and decentralization.

Installation and Setup​

1. Download Package​

Download the package from official release page

wget https://github.com/0glabs/0gchain-ng/releases/download/v1.0.1/galileo-v1.0.1.tar.gz

2. Extract Package​

Unzip this file to your home path

tar -xzvf galileo.tar.gz -C ~

3. Copy Files and Set Permissions​

cd ~/galileo
cp -r 0g-home {your data path}
sudo chmod 777 ./bin/geth
sudo chmod 777 ./bin/0gchaind

4. Initialize Geth​

./bin/geth init --datadir /{your data path}/0g-home/geth-home ./genesis.json

5. Initialize 0gchaind with Temporary Directory​

./bin/0gchaind init {node name} --home /{your data path}/tmp

6. Copy Node Files to 0gchaind Home​

cp /{your data path}/tmp/data/priv_validator_state.json /{your data path}/0g-home/0gchaind-home/data/
cp /{your data path}/tmp/config/node_key.json /{your data path}/0g-home/0gchaind-home/config/
cp /{your data path}/tmp/config/priv_validator_key.json /{your data path}/0g-home/0gchaind-home/config/

Note: The temporary directory can be deleted after this step.

Starting Your Node​

Start 0gchaind with Tmux​

Type tmux to start a new session, then:

cd ~/galileo
CHAIN_SPEC=devnet ./bin/0gchaind start \
    --rpc.laddr tcp://0.0.0.0:26657 \
    --beacon-kit.kzg.trusted-setup-path=kzg-trusted-setup.json \
    --beacon-kit.engine.jwt-secret-path=jwt-secret.hex \
    --beacon-kit.kzg.implementation=crate-crypto/go-kzg-4844 \
    --beacon-kit.block-store-service.enabled \
    --beacon-kit.node-api.enabled \
    --beacon-kit.node-api.logging \
    --beacon-kit.node-api.address 0.0.0.0:3500 \
    --pruning=nothing \
    --home /{your data path}/0g-home/0gchaind-home \
    --p2p.seeds b30fb241f3c5aee0839c0ea55bd7ca18e5c855c1@8.218.94.246:26656 \
    --p2p.external_address {your node ip}:26656

Detach this tmux session by pressing Ctrl+B, then D.

Start Geth with Tmux​

Type tmux to start a new session, then:

cd ~/galileo
./bin/geth --config geth-config.toml --datadir /{your data path}/0g-home/geth-home --networkid 80087

Detach this tmux session by pressing Ctrl+B, then D.

Monitoring Your Node​

Check Chain Status​

Type tmux ls to list sessions, then attach to the 0gchaind session:

tmux attach -t {session_number}

Check logs to confirm your node is running properly.
