0G is the first data availability system with a built-in universal storage layer that is super scalable and decentralized. 0G's scalability relies on the idea of ​​splitting the data availability workflow into a data publishing lane and a data storage lane. The bulk of the data transfer happens on the data storage lane, which is backed by the storage layer, achieving horizontal scalability through well-designed partitions, while the data publishing lane guarantees data availability properties through consensus of data availability sampling, which only requires tiny data to be transmitted through the consensus protocol to avoid bottlenecks in transaction broadcasting.

This guide will walk you through the process of setting up a 0g.AI validator node. You will learn how to:

  • Install and configure the 0g.AI node

  • Get test tokens

  • Create validator information and participate in node verification

1. Since the project requires moderate performance of the equipment, you can use local equipment, or VPS (remote server), etc. to build the node

Recommended node configuration: dual-core 8G 300G hard disk

The following is a detailed construction tutorial:

  1. Execute one-click deployment node script


wget -O 0g.sh https://raw.githubusercontent.com/a3165458/0g.ai/main/0g.sh && chmod +x 0g.sh && ./0g.sh

2. Import wallet/create new wallet (the example is to import wallet)

Get the corresponding EVM address


Extract EVM address command: echo "0x$(evmosd debug addr $(evmosd keys show change here to your wallet name -a) | grep hex | awk '{print $3}')"

3. Create a validator (need to claim water) (DC claiming water is temporarily invalid, only webpage can be used to claim water)

Official website for claiming water: https://faucet.0g.ai/ (You can only claim 0.1, which is quite disappointing)

Enter the official DC: https://discord.com/invite/0glabs


Admin ，bro could you please send me some testnet tokens

The corresponding EVM address extracted in the previous step

Here, both the token and synchronization height must be met before creation, otherwise an error will be reported

4. Go to the website to check your validator's work status:

Validator Explorer: https://explorer.validatorvn.com/OG-Testnet/uptime

At this point, the verifier node is built

If you have created a validator, be sure to back up the file `priv_validator_key.json` in the path $HOME/.evmosd/config/

5.

Update storage node installation

Recommended Configuration

Dual core + 8G + 1T SSD


wget -O 0g.sh https://raw.githubusercontent.com/a3165458/0g.ai/main/0g.sh && chmod +x 0g.sh && ./0g.sh


screen -list


Enter the corresponding path to view logs information

cd log
ls
tail -f zgs.log.2024-04-08

At this point, the storage node deployment is complete

Common commands:

Checking Node Status

evmosd status | jq

Query your authenticator

evmosd q staking validator $(evmosd keys show $WALLET_NAME --bech val -a

Query a validator's missed block counter and jail details

evmosd q slashing signing-info $(evmosd tendermint show-validator)

Release your validator

evmosd tx slashing unjail --from $WALLET_NAME --gas=500000 --gas-prices=99999aevmos -y

Delegate tokens to your validator

evmosd tx staking delegate $(evmosd keys show $WALLET_NAME --bech val -a) <AMOUNT>aevmos --from $WALLET_NAME --gas=500000 --gas-prices=99999aevmos -y

address

evmosd status | jq -r '"\(.NodeInfo.id)@\(.NodeInfo.listen_addr)"'

Edit your validator

evmosd tx staking edit-validator--website="<WEBSITE>" --details="<DESCRIPTION>" --new-moniker="<NEW_MONIKER>" --identity="<KEY BASE PREFIX>" --from=$WALLET_NAME --gas=500000 --gas-prices=99999aevmos -y

control-small-size, 28px); height: var( — control-small-size, 28px);”>

Sending tokens between wallets

evmosd tx bank send $WALLET_NAME <TO_WALLET> <AMOUNT>aevmos --gas=500000 --gas-prices=99999aevmos -y

Check your wallet balance

evmosd q bank balances $(evmosd keys show $WALLET_NAME -a)

Monitor server load

sudo apt update
sudo apt install htop -y
htop

Query active validators

evmosd q staking validators -o json --limit=1000 \
| jq '.validators[] | select(.status=="BOND_STATUS_BONDED")' \
| jq -r '.tokens + " - " + .description.moniker' \
| sort -gr | nl

Query inactive validators

evmosd q staking validators -o json --limit=1000 \
| jq '.validators[] | select(.status=="BOND_STATUS_UNBONDED")' \
| jq -r '.tokens + " - " + .description.moniker' \
| sort -gr | nl

View node logs


pm2 logs evmosd

Restart the node


pm2 restart evmosd

Stop Node

pm2 stop evmosd

Upgrading Nodes


cd 0g-evmos
git fetch
git checkout tags/
make install
evmosd version
# Restrt the node
pm2 restart evmosd && pm2 logs evmosd

Deleting a node from a server

#If you create a validator, be sure to back up the file `priv_validator_key.json` in the path $HOME/.evmosd/config/

pm2 delete evmosd
rm -rf $HOME/.evmosd $HOME/0g-evmos

gRPC usage examples

wget https://github.com/fullstorydev/grpcurl/releases/download/v1.7.0/grpcurl_1.7.0_linux_x86_64.tar.gz
tar -xvf grpcurl_1.7.0_linux_x86_64.tar.gz
chmod +x grpcurl
./grpcurl -plaintext localhost:$GRPC_PORT list

### Make sure gRPC is enabled in app.toml
# grep -A 3 "\[grpc\]" /home/og-testnet-validator/.evmosd/config/app.toml

REST API query examples

curl localhost:$API_PORT/cosmos/staking/v1beta1/validators
