chihuahua-testnet-421

This is a testnet for chihuahua that will start on v1.1.1 and then upgrade to v2.0.0-rc-2.

Installation Steps

Install Prerequisites

The following are necessary to build chihuahua from source.

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

2. Install Go

Follow the instructions here to install Go.

Alternatively, for Ubuntu LTS, you can do:

wget https://golang.org/dl/go1.17.6.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.17.6.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 go1.17.5 linux/amd64

3. Install Chihuahua from source

git clone https://github.com/ChihuahuaChain/chihuahua.git
cd chihuahua
git fetch --tags
git checkout v1.1.1
make install

Note: there is no tag to build off of, just use master for now

Init chain

chihuahuad init $MONIKER_NAME --chain-id chihuahua-testnet-420

Download Genesis

wget -O ~/.chihuahua/config/genesis.json https://raw.githubusercontent.com/pomifer/chihuahua-testnet-420/main/genesis.json

Add Seeds & Persistent Peers

peers="[email protected]:26656"
sed -i.bak -e "s/^seeds *=.*/seeds = \"$seeds\"/; s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" ~/.chihuahua/config/config.toml

Update minimum-gas-prices in app.toml

minimum-gas-prices = 0.025uhuahua

Add/recover keys

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

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

Create a service

This will restart the process in case of process crash or server restart.

Create a /etc/systemd/system/chihuahuad.service file as root with:

[Unit]
Description=Chihuahua Node
After=network-online.target

[Service]
User=<your-user>
ExecStart=/home/<your-user>/go/bin/chihuahuad start
Restart=always
RestartSec=3
LimitNOFILE=4096

[Install]
WantedBy=multi-user.target

Note: replace the 2 <your-user> with your user/path and remove the User= line in case of root

# Enable on server restart 
sudo systemctl enable chihuahuad

# Start the service
sudo systemctl start chihuahuad

# Show logs
sudo journalctl -u chihuahuad.service -f

Instructions for post-genesis validators

Create the validator

Note that proposal #1 agrees that all validators set commission to at least 5%!

chihuahuad tx staking create-validator \
  --from "<key-name>" \
  --amount "10000000uhuahua" \
  --pubkey "$(chihuahuad tendermint show-validator)" \
  --chain-id "chihuahua-testnet-420" \
  --moniker "<moniker>" \
  --commission-max-change-rate 0.01 \
  --commission-max-rate 0.20 \
  --commission-rate 0.10 \
  --min-self-delegation 1 \
  --details "<details>" \
  --security-contact "<contact>" \
  --website "<website>" \
  --gas-prices "0.025uhuahua"
