# Become a Desmos validator

Validators are responsible for committing new blocks to the blockchain through voting. A validator's stake is slashed if they become unavailable or sign blocks at the same height. Please read about Sentry Node Architecture to protect your node from DDOS attacks and to ensure high-availability.

Warning

If you want to become a validator for the mainnet, you should research security.

# 1. Run a fullnode

To become a validator, you must first have desmos installed and be able to run a fullnode. You can first setup your fullnode if you haven't yet.

Not enough funds? Google Cloud can help you

Running a validator node should be done on a separate machine, not your local computer. This is due to the fact that validators need to be constantly running to avoid getting slashed (and thus loosing funds). We highly recommend setting up a local machine that can run 24/7, even a Raspberry can do the job.

If you do not have the possibility of using a local machine, even an hosted server can be perfect. If you wish to get started for free, you can use the 300$ Google Cloud bonus (opens new window). This should be enough to run a validator for 5-6 months.

# 2. Create your validator

In order to create a validator, you need to have to create a local wallet first. This will be used in order to hold the tokens that you will later delegate to your validator node, allowing him to properly work. In order to create this wallet, please run:

desmos keys add <key_name>

Key name

Please select a key name that you will easily remember and be able to type fast. This name will be used all over the places inside other commands later.

Once that you have created your local wallet, it's time to get some tokens to be used as the initial validator stake so that it can run properly. If you are setting up a validator inside one of our testnets, you can request some testnet tokens inside our Discord (opens new window). Once you have joined, go inside the #ask-tokens channel and run the following command:

!send <your_address>

You can get your address by running:

desmos keys show <key_name> -a

To run a validator node you need to first get your current validator public key that was created when you ran desmod init. Your desmosvalconspub (Desmos Validator Consensus Pubkey) can be used to create a new validator by staking tokens. You can find your validator pubkey by running:

desmos tendermint show-validator

To create your validator, just use the following command:

Don't use more staking token than you have!

On Morpheus testnet, we are using udaric as the staking token and it will be the example below.

We are going to use udesmos as the staking token on Mainnet.

desmos tx staking create-validator \
  --amount=1000000udaric \
  --pubkey=$(desmos tendermint show-validator) \
  --moniker="<Your moniker here>" \
  --chain-id=<chain_id> \
  --commission-rate="0.10" \
  --commission-max-rate="0.20" \
  --commission-max-change-rate="0.01" \
  --min-self-delegation="1" \
  --gas="auto" \
  --gas-adjustment="1.2" \
  --gas-prices="0.025udaric" \
  --from=<key_name>

TIP

When specifying the value of the moniker flag, please keep in mind this is going to be the public name associated to your validator. For this reason, it should represent your company name or something else that can easily identify you among all the other validators.

TIP

When specifying commission parameters, the commission-max-change-rate is used to measure % point change over the commission-rate. E.g. 1% to 2% is a 100% rate increase, but only 1 percentage point.

TIP

Min-self-delegation is a stritly positive integer that represents the minimum amount of self-delegated staking token your validator must always have. A min-self-delegation of 1 means your validator will never have a self-delegation lower than 1udaric. A valdiator self delegate lower than this number will automatically be unbonded.

You can confirm that you are in the validator set by using a block explorer, e.g. Big Dipper (opens new window).

# 3. Edit the validator description

You can edit your validator's public description. This info is to identify your validator, and will be relied on by delegators to decide which validators to stake to. Make sure to provide input for every flag below. If a flag is not included in the command the field will default to empty (--moniker defaults to the machine name) if the field has never been set or remain the same if it has been set in the past.

The <key_name> specifies which validator you are editing. If you choose to not include certain flags, remember that the --from flag must be included to identify the validator to update.

The --identity can be used as to verify identity with systems like Keybase or UPort. When using with Keybase --identity should be populated with a 16-digit string that is generated with a keybase.io (opens new window) account. It's a cryptographically secure method of verifying your identity across multiple online networks. The Keybase API allows some block explorers to retrieve your Keybase avatar. This is how you can add a logo to your validator profile.

desmos tx staking edit-validator \
  --moniker="choose a moniker" \
  --website="https://desmos.network" \
  --identity=6A0D65E29A4CBC8E \
  --details="To infinity and beyond!" \
  --commission-rate="0.10" \
  --chain-id=<chain_id> \
  --from=<key_name>

Note: The commission-rate value must adhere to the following invariants:

  • Must be between 0 and the validator's commission-max-rate
  • Must not exceed the validator's commission-max-change-rate which is maximum % point change rate per day. In other words, a validator can only change its commission once per day and within commission-max-change-rate bounds.

# View the validator description

View the validator's information with this command:

desmos query staking validator <account_desmos>

desmos tx slashing unjail \
	--from=<key_name> \
	--chain-id=<chain_id>

# 4. Confirm your validator is running

Your validator is active if the following command returns anything:

desmos query tendermint-validator-set | grep $(desmos status 2>&1 | jq '.ValidatorInfo.PubKey.value')

When you query the node status with desmos status, it includes the validator pubkey in base64 encoding. If your node is an active validator, the validator pubkey will be shown when you query the validator set.

You should now see your validator in one of the Desmos explorers. You are looking for the bech32 encoded operator address starts with desmosvaloper. It is another representation of your <key_name> that you have used to create this validator.

To show the operator address, you can run

desmos keys show <key_name> -a --bech val

Note To be in the validator set, you need to have more total voting power than the 200th validator.
