Terp-Node Base Setup

Hardware Requirements

• Minimal
  • 4 GB RAM
  • 100 GB SSD
  • 3.2 x4 GHz CPU
• Recommended
  • 8 GB RAM
  • 1 TB NVME SSD
  • 3.2 GHz x4 GHz CPU

Operating System

• Recommended
  • Linux(x86_64)

Installation Steps

1. Basic Packages

# update the local package list and install any available upgrades 
sudo apt-get update && sudo apt upgrade -y 
# install toolchain and ensure accurate time synchronization 
sudo apt-get install make build-essential gcc git jq chrony -y

# install gcc & make
sudo apt install gcc && sudo apt install make

2. Install Go

Follow the instructions here to install Go.

Alternatively, for Ubuntu LTS, you can do:

wget https://golang.org/dl/go1.19.0.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.19.0.linux-amd64.tar.gz

Unless you want to configure in a non standard way, then set these in the .profile in the user's home (i.e. ~/) folder.

cat <<EOF >> ~/.profile
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GO111MODULE=on
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
EOF
source ~/.profile
go version

Output should be: go version go1.19.0 linux/amd64

Install terpd from source

1. Clone repository

• Clone git repository

git clone https://github.com/terpnetwork/terp-core.git

• Checkout latest tag

cd terp-core
git fetch --tags
git checkout v0.1.0

2. Install CLI

make build && make install

To confirm that the installation was successful, you can run:

terpd version

Output should be: v0.1.0

Instruction for new validators

Init

terpd init "$MONIKER_NAME" --chain-id $CHAIN_ID

Generate keys

# To create new keypair - make sure you save the mnemonics!
terpd keys add <key-name> 

or

# Restore existing terp wallet with mnemonic seed phrase. 
# You will be prompted to enter mnemonic seed. 
terpd keys add <key-name> --recover

or

# Add keys using ledger
terpd keys show <key-name> --ledger

Check your key:

# Query the keystore for your public address 
terpd keys show <key-name> -a

Validator Setup Instructions

Set minimum gas fees

perl -i -pe 's/^minimum-gas-prices = .+?$/minimum-gas-prices = "0.0125ucgas"/' ~/.terp/config/app.toml

Add persistent peers

Download new genesis file

curl https://raw.githubusercontent.com/terpnetwork/net/main/mainnet/v1.1/genesis.json > ~/.terp/config/genesis.json

Setup Unit/Daemon file

# 1. create daemon file
touch /etc/systemd/system/terpd.service
# 2. run:
cat <<EOF >> /etc/systemd/system/terpd.service
[Unit]
Description=Terp Net daemon
After=network-online.target
[Service]
User=<USER>
ExecStart=/home/<USER>/go/bin/terpd start
Restart=on-failure
RestartSec=3
LimitNOFILE=4096
[Install]
WantedBy=multi-user.target
EOF
# 3. reload the daemon
systemctl daemon-reload
# 4. enable service - this means the service will start up 
# automatically after a system reboot
systemctl enable terpd.service
# 5. start daemon
systemctl start terpd.service

In order to watch the service run, you can do the following:

journalctl -u terpd.service -f

Congratulations! You now have a full node. Once the node is synced with the network, you can then make your node a validator.

Create validator

1. Transfer funds to your validator address. A minimum of 1 (1000000uterp) is required to start a validator.

2. Confirm your address has the funds.

terpd q bank balances $(terpd keys show -a <key-alias>)

1. Run the create-validator transaction **Note: 1,000,000 uterpx = 1 , so this validator will start with 1 **

terpd tx staking create-validator \ 
--amount 1000000uterp \ 
--commission-max-change-rate "0.05" \ 
--commission-max-rate "0.10" \ 
--commission-rate "0.05" \ 
--min-self-delegation "1" \ 
--details "validators write bios too" \ 
--pubkey $(terpd tendermint show-validator) \ 
--moniker $MONIKER_NAME \ 
--chain-id $CHAIN_ID \ 
--fees 2000upersy \
--from <key-name>

To ensure your validator is active, run:

terpd q staking validators | grep moniker

Backup critical files

priv_validator_key.json
node_key.json

Instruction for old validators

Stop node

systemctl stop terpd.service

Install latest Terpd from source

Install latest Terpd

Download genesis file

curl https://raw.githubusercontent.com/terpnetwork/net/main/mainnet/genesis.json > ~/.terp/config/genesis.json

Clean old state

terpd unsafe-reset-all

Rerun node

systemctl daemon-reload
systemctl start terpd.service
