Become a validator
To become a validator, you will need to use LUKSO Deposit Launchpad to deposit 32 LYX per validator. Once you have generated your keystore files (
keystore-xxx-[timestamp].json) and deposited the LYX, you can adjust your node to run as a validator.
Starting a validator
Similar to running a regular node, you have multiple options to start your validator. Please refer to the regular Node Guide that explains the differences between those setups and how to get the correct network configurations.
📦 With Dappnode
The Dappnode tutorial explains the process.
📟 With LUKSO CLI
Set up your regular node using the LUKSO CLI as described in the Node Guide.
Importing Validator Keys
The name of the directory
myLUKSOnode/ in the example below can be changed according to your preferences.4
If it is set up correctly and all clients are working, you can continue importing your validator keys into the validator wallet. You will be asked to set a new wallet password to store the imported deposit keys safely. Further, you will have to input your password for the deposit keys you want to import so that they can be encrypted and added to the wallet. The new keystore files will be stored under the
lukso validator import --validator-keys "./path/to/your/keys/folder"
Checking Validator Keys
After importing one or multiple folders, you can check your imported keys.
lukso validator list
If the imported deposit keys match the ones in the original folder, you can delete them from your node machine.
Starting the Validator
After importing your keys, you can start the node with the validator functionality. If the node is already synced and running, the
lukso start command will restart all clients automatically.
To start the validator, you have to pass a minimum of 2 flags:
--validator: Will start the installed and configured clients, including the validator
--transaction-fee-recipient: Specifies your transaction fee recipient address, which will receive all block rewards and tips from transactions. The address can be any EOA address you have control over on a wallet like MetaMask, Ledger, or any other wallet with the functionality to connect with LUKSO or custom networks.
If you want to set custom flags to the start command, like the graffiti or a custom stat page connection, make sure to add them. You can find more information about passing options to the client on the official LUKSO CLI Documentation.
The recipient fee address can also be different than the withdrawal credential you added to your validator key when you generated them. The withdrawal address is used to withdraw rewards and staked amounts connected to the consensus mechanism after the Shapella upgrade is implemented on the LUKSO blockchain. The feature is planned some months after the network launch.
As only genesis validators can run the validator on a node, you must select your chosen initial supply for the LUKSO mainnet. More information can be found in the official Mainnet Timeline article.
Without specifying any flags, the node starts its normal synchronization process.
If you want more convenience and your validator to operate quickly, you can also use checkpoints. Checkpoint synchronization is a feature that significantly speeds up the initial sync time of the consensus client. If enabled, your node will begin syncing from a recently finalized consensus checkpoint instead of genesis. It will then download the rest of the blockchain data while your consensus is already running.
After the synchronization is finalized, you will end up with the equal blockchain data. You can use the flag on every startup. However, it shows the most significant effect when synchronizing from scratch or after an extended downtime. The shortcut is ideal for fresh installations, validator migration, or recovery.
- Regular Synchronization
- Checkpoint Synchronization
The synchronization process will take multiple hours for the validator to participate in the consensus.
lukso start --validator --transaction-fee-recipient "0x1234..."
The shortcut is ideal for making installation, validator migration, or recovery much faster.
If you are setting up a node for the testnet, add the
--testnet flag to the start command.
You will need the LUKSO CLI Version 0.8.0 or above in order to use the
--checkpoint-sync command. If you are using an older version, please pass down the checkpoint flag as described in the LUKSO CLI Documentation.
# Starting the Mainnet Validator
lukso start --validator --transaction-fee-recipient "0x1234" --checkpoint-sync
Checking Validator Logs
To check that everything is running correctly, you can see the status of all your clients using the status command.
# INFO PID 39424 - Execution (geth): Running 🟢
# INFO PID 39430 - Consensus (prysm): Running 🟢
# INFO PID 39432 - Validator (validator): Running 🟢
In addition to the consensus and execution clients, you can now further check the validator logs using the LUKSO CLI:
# Viewing the logs of the validator client
lukso logs validator
For more options, please check the LUKSO CLI Documentation.
To enable more advanced monitoring for your node, you can check the official
network-docker-monitoring repository with a step-by-step guide.
🚢 With Docker
If you are using Docker images in your setup, you need to make sure you have activated the validator related options.
