Oraid Installation and setup

You can see step of install and setup oraid here

Initialize Orai Testnet Node

Use oraid to initialize your node (replace the NODE_NAME with a name of your choosing):

oraid init NODE_NAME --home $ORAI_HOME/.oraid --chain-id Oraichain-fork

Download and place the genesis file in the orai config folder:

sudo apt-get install wget liblz4-tool aria2 -y
wget -O $ORAI_HOME/.oraid/config/genesis.tar.lz4 https://orai.s3.us-east-2.amazonaws.com/testnet/genesis.tar.lz4
lz4 -c -d $ORAI_HOME/.oraid/config/genesis.tar.lz4 | tar -x -C $ORAI_HOME/.oraid/config/
rm -rf $ORAI_HOME/.oraid/config/genesis.tar.lz4 

Finally, your working directory should be like below:

$ORAI_HOME/.oraid/
├── config
│   ├── app.toml
│   ├── client.toml
│   ├── config.toml
│   ├── genesis.json
│   ├── node_key.json
│   └── priv_validator_key.json
└── data
    └── priv_validator_state.json

State-sync Oraichain testnet

• Create state-sync.sh file with the following code:

#!/bin/bash

APP_TOML_PATH=$ORAI_HOME/.oraid/config/app.toml
CONFIG_TOML_PATH=$ORAI_HOME/.oraid/config/config.toml

• Grant privilege to execute script:

chmod 700 state-sync.sh
./state-sync.sh

• Start your node

oraid tendermint unsafe-reset-all --home $ORAI_HOME/.oraid
oraid start --home $ORAI_HOME/.oraid

Start node process may take many minutes!
