MAINNET: CHIHUAHUA-1

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/go1.17.5.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.17.5.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
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-1

Download Genesis

wget -O ~/.chihuahua/config/genesis.json https://raw.githubusercontent.com/ChihuahuaChain/mainnet/main/genesis.json

Add Seeds & Persistent Peers

sed -i.bak -e "s/^seeds *=.*/seeds = \"$seeds\"/; s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" ~/.chihuahua/config/config.toml

Customize Pruning and Indexing (Optional)

Due to the high number of transactions on the chain in order to save some hard disk space you might want to tweak pruning and indexing as follows

• Replace 'kv' to 'null' on ~/.chihuahua/config.toml

indexer = "null"

• Set pruning as follows on ~/.chihuahua/app.toml

pruning = "custom"

# These are applied if and only if the pruning strategy is custom.
pruning-keep-recent = "5000"
pruning-keep-every = "0"
pruning-interval = "10"

NOTE: If your node was already active before pruning tweaks you will need to resync from scratch again, if you only turned off the indexing you can simply restart your node and erase ~/.chihuahua/data/tx_index.db folder.

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
