My guide for installing and launching the validator node of the 0G labs project

This article will tell you how to install the validator node of the 0G LABS project. I decided to write a guide for this particular project, as I really like its technical part and once I myself faced the problem of installing it.

Testnet Configuration

Let's talk about the parameters of this project. The data is presented below in an easy-to-understand format, just come back here if you forgot anything.

Chain-Name - 0G-Newton-Testnet
Chain-ID - zgtendermint_16600-2
Token-Symbol - A0GI
Chain-RPC - https://rpc-testnet.0g.ai
Chain-Websocket - wss://rpc-testnet.0g.ai/ws
Storage-RPC - https://rpc-storage-testnet.0g.ai

Also, for your convenience, I will post the official explorers and a link to the faucet here:

FAUCET - https://faucet.0g.ai/
Chain-Explorer - https://chainscan-newton.0g.ai/
Storage-Explorer - https://storagescan-newton.0g.ai/

Hardware Requirement

RAM - 64 GB
CPU - 8 cores
Disk - 1 TB NVME SSD
Bandwidth - 100 MBps

Before you start, make sure that you have a UTC time zone set, if you have a different time zone, then you may get an error!

timedatectl set-timezone UTC

This command will help you change your time zone

Install 0g via CLI

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

Set Chain ID

0gchaind config chain-id zgtendermint_16600-2

Initialize Node

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

Download `genesis.json` 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.js
0gchaind validate-genesison

The last command from the list verifies that genesis is correct.if you have an error at this stage, then try to delete the downloaded file and install it again.

Add Seeds

In order for our node to start and be able to connect to the network, we need to specify the seeds. I suggest using the following seeds, which are presented in the official community of the project.

[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656

The data should be inserted in this format: seeds = "<node-id>@<ip>:<p2p port>". The configuration file is located in this path: $HOME/.0gchain/config/config.toml

Start Testnet

Now we have to start the node and wait for the synchronization to take place. The node is launched with the following command:

0gchaind start

Create Validator

As soon as the synchronization takes place, you will be able to create a wallet and replenish it through the FAUCET.

0gchaind keys add <key_name> --eth

The command to create a validator. It only works after you have touched the faucet and checked that your balance has been replenished!

0gchaind tx staking create-validator \
  --amount=<staking_amount>ua0gi \
  --pubkey=$(0gchaind tendermint show-validator) \
  --moniker="<your_validator_name>" \
  --chain-id=zgtendermint_16600-2 \
  --commission-rate="0.10" \
  --commission-max-rate="0.20" \
  --commission-max-change-rate="0.01" \
  --min-self-delegation="1" \
  --from=<key_name> \
  --gas=auto \
  --gas-adjustment=1.4

I congratulate you, if you have come this far, then most likely you have managed to create your own validator. Remember that only the top 125 validators will become validators!
