Running a Testnet Validator Node

  • Minimal
    • 4 GB RAM
    • 250 GB SSD Storage
    • 1.4 GHz x2 CPU
  • Recommended
    • 8 GB RAM
    • 500 GB SSD Storage
    • 2.0 GHx x4 CPU

  • Run the following to generate a wallet. Save the mnemonic displayed on the output, which can be used for scenarios where you would like to import your wallet address.
hid-noded keys add <key-name>
  • If you already have a BIP39 mnemonic, you can import your wallet by running the following. Enter the mnemonic string in the prompt and the wallet will be imported.
hid-noded keys add <key-name> --recover

  • Initialise the node with a moniker name.
hid-noded init <moniker-name> --chain-id jagrat
Configuration files of the node are stored in the default location: $HOME/.hid-node. If you want to specify a different location, append the flag --home <hid-node-home-directory> to the above command.
  • Replace genesis.json present in <hid-node-home-directory>/config with the Testnet genesis here.
  • Copy the final peers from here. Open <hid-node-home-directory>/config/config.toml and the add the peers in the field persistent_peers.
  • Set the minimum-gas-price in <hid-node-home-directory>/config/app.toml.

Cosmovisor is a tool which will enable automatic upgrade of a blockchain, once a software upgrade governance proposal is passed. More information on Cosmovisor here.
  • Download and Install Cosmovisor
wget https://github.com/cosmos/cosmos-sdk/releases/download/cosmovisor%2Fv1.2.0/cosmovisor-v1.2.0-linux-amd64.tar.gz && tar -C /usr/local/bin/ -xzf cosmovisor-v1.2.0-linux-amd64.tar.gz
  • Export the following environment variables which are needed by cosmovisor
export DAEMON_NAME=hid-noded
export DAEMON_PATH=<Complete Path of Blockchain Binary>
export DAEMON_HOME=<Blockchain Config Path Directory>/.hid-node # Example: $HOME/.hid-node
  • Create a cosmovisor and copy the existing blockchain binary to the following location
mkdir -p $DAEMON_HOME/cosmovisor/genesis/bin
cp $DAEMON_PATH $DAEMON_HOME/cosmovisor/genesis/bin
  • Start node using Cosmovisor
cosmovisor run start

  • Acquire some $HID tokens. (TODO: Mention the approach to acquire tokens: faucet or Discord group)
  • Perform a validator creation transaction.
hid-noded tx staking create-validator \
--from <key-name> \
--amount 1000000000000uhid \
--pubkey "$(hid-noded tendermint show-validator)" \
--chain-id jagrat \
--moniker="<validator-name>" \
--commission-max-change-rate=0.01 \
--commission-max-rate=1.0 \
--commission-rate=0.07 \
--min-self-delegation="500000000000" \
--details="XXXXXXXX" \
--security-contact="XXXXXXXX" \
--website="XXXXXXXX"

Having significant stake in the blockchain comes with reward in the form of tokens. The redemption of rewards needs to be done manually. Run the following to redeem rewards:
hid-noded tx distribution withdraw-rewards <validator-addr> --from <validator-wallet-address>
  • <validator-addr> - Validator's Operator address. (Prefix is hidvaloper)
  • <validator-wallet-address> - Validator's wallet address from which they have stake tokens. (Prefix hid)
If you also want to withdraw validator commission, append the --commission flag to the above command.
To check the outstanding validator rewards.
hid-noded q distribution validator-outstanding-rewards <validator-addr>
  • <validator-addr> - Validator's Operator address. (Prefix is hidvaloper)
