haqq node setup for testnet — haqq_54211-2

Official documentation:

Explorer:

Usefull tools and references

To set up monitoring for your validator node navigate to Set up monitoring and alerting for haqq validator

To migrate your validator to another machine read Migrate your validator to another machine

Hardware Requirements

Like any Cosmos-SDK chain, the hardware requirements are pretty modest.

Minimum Hardware Requirements

  • 4x CPUs; the faster clock speed the better
  • 8GB RAM
  • 100GB of storage (SSD or NVME)
  • Permanent Internet connection (traffic will be minimal during testnet; 10Mbps will be plenty - for production at least 100Mbps is expected)

Recommended Hardware Requirements

  • 8x CPUs; the faster clock speed the better
  • 64GB RAM
  • 1TB of storage (SSD or NVME)
  • Permanent Internet connection (traffic will be minimal during testnet; 10Mbps will be plenty - for production at least 100Mbps is expected)

Set up your haqq fullnode

Option 1 (automatic)

You can setup your haqq fullnode in few minutes by using automated script below. It will prompt you to input your validator node name!

wget -O haqq.sh https://raw.githubusercontent.com/kj89/testnet_manuals/main/haqq/haqq.sh && chmod +x haqq.sh && ./haqq.sh

Option 2 (manual)

You can follow manual guide if you better prefer setting up node manually

Post installation

When installation is finished please load variables into system

source $HOME/.bash_profile

Next you have to make sure your validator is syncing blocks. You can use command below to check synchronization status

haqqd status 2>&1 | jq .SyncInfo

(OPTIONAL) Snapshot

You can state sync your node in minutes by running commands below

sudo systemctl stop haqqd
rm -rf $HOME/.haqqd/data/
mkdir $HOME/.haqqd/data/

cd $HOME
wget http://88.198.34.226:7150/haqqddata.tar.gz

tar -C $HOME/ -zxvf haqqddata.tar.gz --strip-components 1
wget -O $HOME/.haqqd/data/priv_validator_state.json "https://raw.githubusercontent.com/obajay/StateSync-snapshots/main/Canto/priv_validator_state.json"
cd && cat .haqqd/data/priv_validator_state.json

cd $HOME
rm haqqddata.tar.gz
systemctl restart haqqd && journalctl -u haqqd -f -o cat

Create wallet

To create new wallet you can use command below. Don’t forget to save the mnemonic

haqqd keys add $WALLET

(OPTIONAL) To recover your wallet using seed phrase

haqqd keys add $WALLET --recover

To get current list of wallets

haqqd keys list

Save wallet info

Add wallet and valoper address into variables

HAQQ_WALLET_ADDRESS=$(haqqd keys show $WALLET -a)
HAQQ_VALOPER_ADDRESS=$(haqqd keys show $WALLET --bech val -a)
echo 'export HAQQ_WALLET_ADDRESS='${HAQQ_WALLET_ADDRESS} >> $HOME/.bash_profile
echo 'export HAQQ_VALOPER_ADDRESS='${HAQQ_VALOPER_ADDRESS} >> $HOME/.bash_profile
source $HOME/.bash_profile

Fund your wallet

In order to create validator first you need to fund your wallet with testnet tokens.

https://testedge2.haqq.network/

Create validator

Before creating validator please make sure that you have at least 1 strd (1 strd is equal to 1000000 aISLM) and your node is synchronized

To check your wallet balance:

haqqd query bank balances $HAQQ_WALLET_ADDRESS

If your wallet does not show any balance than probably your node is still syncing. Please wait until it finish to synchronize and then continue

To create your validator run command below

haqqd tx staking create-validator \
  --amount 100000000aISLM \
  --from $WALLET \
  --commission-max-change-rate "0.01" \
  --commission-max-rate "0.2" \
  --commission-rate "0.07" \
  --min-self-delegation "1" \
  --pubkey  $(haqqd tendermint show-validator) \
  --moniker $NODENAME \
  --chain-id $HAQQ_CHAIN_ID

Security

To protect you keys please make sure you follow basic security rules

Set up ssh keys for authentication

Good tutorial on how to set up ssh keys for authentication to your server can be found here

Basic Firewall security

Start by checking the status of ufw.

sudo ufw status

Sets the default to allow outgoing connections, deny all incoming except ssh and 26656. Limit SSH login attempts

sudo ufw default allow outgoing
sudo ufw default deny incoming
sudo ufw allow ssh/tcp
sudo ufw limit ssh/tcp
sudo ufw allow ${HAQQ_PORT}656,${HAQQ_PORT}660/tcp
sudo ufw enable

Monitoring

To monitor and get alerted about your validator health status you can use my guide on Set up monitoring and alerting for haqq validator

Calculate synchronization time

This script will help you to estimate how much time it will take to fully synchronize your node
It measures average blocks per minute that are being synchronized for period of 5 minutes and then gives you results

wget -O synctime.py https://raw.githubusercontent.com/kj89/testnet_manuals/main/haqq/tools/synctime.py && python3 ./synctime.py

Check your validator key

[[ $(haqqd q staking validator $HAQQ_VALOPER_ADDRESS -oj | jq -r .consensus_pubkey.key) = $(haqqd status | jq -r .ValidatorInfo.PubKey.value) ]] && echo -e "\n\e[1m\e[32mTrue\e[0m\n" || echo -e "\n\e[1m\e[31mFalse\e[0m\n"

Get list of validators

haqqd q staking validators -oj --limit=3000 | jq '.validators[] | select(.status=="BOND_STATUS_BONDED")' | jq -r '(.tokens|tonumber/pow(10; 6)|floor|tostring) + " \t " + .description.moniker' | sort -gr | nl

Get currently connected peer list with ids

curl -sS http://localhost:${HAQQ_PORT}657/net_info | jq -r '.result.peers[] | "\(.node_info.id)@\(.remote_ip):\(.node_info.listen_addr)"' | awk -F ':' '{print $1":"$(NF)}'
