# 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.
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
desmoscli 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. This should be enough to run a validator for 5-6 months.
Previously gone thought a Primer challenge? Reset your `desmoscli`
If you've previously gone through a Primer challenge, you need to make sure your
demoscli is properly setup to communicate with your node. In order to do so, please execute the following command:
# 2. Create your validator
desmosvalconspub (Desmos Validator Consensus Pubkey) can be used to create a new validator by staking tokens. You can find your validator pubkey by running:
desmosd 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.
desmoscli tx staking create-validator \ --amount=1000000udaric \ --pubkey=$(desmosd tendermint show-validator) \ --moniker="choose a moniker" \ --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>
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.
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.
# 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.
--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 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.
desmoscli tx staking edit-validator --moniker="choose a moniker" \ --website="https://desmos.network" \ --identity=6A0D65E29A4CBC8E \ --details="To infinity and beyond!" \ --chain-id=<chain_id> \ --from=<key_name> \ --commission-rate="0.10"
commission-rate value must adhere to the following invariants:
- Must be between 0 and the validator's
- Must not exceed the validator's
commission-max-change-ratewhich is maximum % point change rate per day. In other words, a validator can only change its commission once per day and within
# View the validator description
View the validator's information with this command:
desmoscli query staking validator <account_desmos>
desmoscli 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:
desmoscli query tendermint-validator-set | grep "$(desmosd tendermint show-validator)"
You should now see your validator in one of the Desmos explorers. You are looking for the
address in the
To be in the validator set, you need to have more total voting power than the 100th validator.
