Running a Validator on Coreum Network

Setting up and running a validator on the Coreum network is a crucial role that contributes to the network’s security and efficiency. This guide covers the essential steps and best practices for running a successful validator node on Coreum.

Initial Setup

Prerequisites

• cored Installation: Ensure that cored is installed and configured to connect to the desired Coreum network.
• Funded Account: Ensure you have a funded account to cover transaction fees for validator registration.

Validator Creation

Generating a Validator Key

• Generate a new validator key pair using the cored CLI:

      cored keys add <validator_key_name> --keyring-backend <keyring_backend>
  
      
  

  Replace <validator_key_name> with your desired key name and <keyring_backend> with your keyring backend choice.

Registering the Validator

• Register your validator by submitting a transaction with the necessary parameters:

      cored tx staking create-validator \
    --amount <staking_amount> \
    --pubkey <validator_pubkey> \
    --moniker <validator_moniker> \
    --commission-rate <commission_rate> \
    --commission-max-rate <commission_max_rate> \
    --commission-max-change-rate <commission_max_change_rate> \
    --min-self-delegation <min_self_delegation> \
    --from <your_account_key_name> \
    --gas auto \
    --chain-id <chain_id> \
    --keyring-backend <keyring_backend> \
    --node <node_url>
  
      
  

  Replace the placeholders appropriately based on your setup.

Monitoring Your Validator

• After registering, monitor the network for the validation of your transaction and the active participation of your validator in the consensus process.

Security Practices

Key Management

• Securely manage and store your validator keys. Regularly update and back up your keys to prevent loss.

Node Security

• Consider using additional security measures like sentry nodes if your validator is exposed to the public internet.

Validator Maintenance

Monitoring and Updating

• Regularly check the performance and health of your validator node. Ensure your software is updated to the latest stable version.

Participating in Governance

• Stay informed about governance proposals and actively participate in the voting process using:

      cored tx gov vote <proposal_id> <option> --from <your_key_name>
  
      
  

Troubleshooting and Support

Common Issues

• Downtime: Minimize downtime to avoid penalties.
• Double Signing: Ensure your setup prevents double signing, which could lead to slashing.

Seeking Help

• Engage with the Coreum community through forums or chat channels for additional support and troubleshooting tips.

For detailed commands and further instructions, refer to the Coreum documentation. Running a validator on Coreum is a significant responsibility that comes with potential rewards through active participation in the network’s governance and consensus processes.
