Create your own account if you don’s have one

This account acts as the corresponding validator operator for yourself.

**Important** write this seed phrase in a safe place.
It is the only way to recover your account if you ever forget your password.

Initialize your node

Initialize the configuration files such as genesis.json and config.toml

iris init --home={path_to_your_home} --chain-id=fuxi-6000 --moniker={your-name}

This command will create the corresponding files in the home directory.

Get Genesis and Config Files

Replace genesis and config file in $IRIShome/config with the ones from testnet GitHub repo:

wget https://raw.githubusercontent.com/irisnet/testnets/master/fuxi/fuxi-6000/config/config.toml
wget https://raw.githubusercontent.com/irisnet/testnets/master/fuxi/fuxi-6000/config/genesis.json

Start your node

Now start your node and catch up with your peers.

iris start

Upgrade to become a Validator node

First, you need to make sure that your account balance is not zero. You can always get some IRIS by using the Faucet. The faucet will send you 10IRIS every request, Please don't abuse it.

Once you have created your own address, please then you could use this account to stake as a validatord. The following command is used to check the balance of your account:

iriscli bank account <ACCOUNT> --node=http://localhost:26657

Then you need to make sure that your validator node is synced

iriscli status — node=tcp://localhost:26657

You should also be able to see catching_up is false.

You need to get the public key of your node before upgrade your node to a validator node. The public key of your node starts with fvp, it can be used to create a new validator by staking tokens. To understand more about the address encoding in IRISHub, please read this doc

You can find your validator’s pubkey by running:

iris tendermint show-validator — home=<IRIS-HOME>

Next, use the output as pubkey field for iriscli stake create-validator command:

iriscli stake create-validator --amount=10iris --pubkey=<pubkey> --moniker=<moniker> --fee=0.05iris --gas=2000000 --chain-id=fuxi-6000

Confirm Your Validator is Running

Your validator is active if the following command returns anything:

iriscli status — node=tcp://localhost:26657

You should also be able to see your power is above 0 if your bonded toke is in top 100. Also, you should see validator on the Explorer.
