Validator Node

<aside> 👉 Hardware Requirement

- Memory: 64 GB
- CPU: 8 cores
- Disk: 1 TB NVME SSD
- Bandwidth: 100 MBps for Download / Upload

</aside>

Install 0gchaind via CLI

git clone -b v0.2.3 <https://github.com/0glabs/0g-chain.git>
./0g-chain/networks/testnet/install.sh
source ~/.profile

0gchaind config chain-id zgtendermint_16600-2

Initialize Node

<aside> 👉 We need to initialize the node to create all the necessary validator and node configuration files:

0gchaind init <your_validator_name> --chain-id zgtendermint_16600-2

By default, the init command creates config and data folder under ~/.0gchain(i.e $HOME). In the config directory, the most important files for configuration are app.toml and config.toml.

</aside>

Genesis & Seeds

<aside> 👉 Copy the Genesis File

sudo apt install -y unzip wget
rm ~/.0gchain/config/genesis.json
wget -P ~/.0gchain/config <https://github.com/0glabs/0g-chain/releases/download/v0.2.3/genesis.json>

Then verify the correctness of the genesis configuration file:

0gchaind validate-genesis

</aside>

<aside> 👉 Add Seed Nodes

Your node needs to know how to find peers. You’ll need to add healthy seed nodes to $HOME/.0gchain/config/config.toml.

Start Node

<aside> 👉 Start the node and sync up to the latest block height. Note that the first time you start the sync up, it may take longer time to run.

0gchaind start

The process of installing and launching a node is quite simple. If you followed my guide, then you definitely succeeded!
