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.
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.
The rest of the documentation will assume you have followed our instructions and have successfully set up a fullnode.
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.
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>
or use the
--recover flag if you already have a secret recovery phrase (mnemonic phase) you'd want to use:
desmos keys add <key_name> --recover
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.
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
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 Mainnet, we are using
udsm as the staking token and it will be the example below.
desmos tx staking create-validator \ --amount=1000000udsm \ --pubkey=$(desmos tendermint show-validator) \ --moniker="<Your moniker here>" \ --chain-id=desmos-mainnet \ --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="0.025udsm" \ --from=<key_name>
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.
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 strictly 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
1DSM. 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.
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.
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=desmos-mainnet \ --from=<key_name>
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's information with this command:
desmos query staking validator <account_desmos>
desmos tx slashing unjail \ --from=<key_name> \ --chain-id=desmos-mainnet-1
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
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
To be in the validator set, you need to have more total voting power than the 200th validator.
