You will find all testnet implementations of the Cosmic Horizon Network in this repository.

Genesis: coming soon

Git tag: coho v0.1

Block explorer: coming soon

Seeds: TBA

Here are the minimal hardware configs required for running a validator/sentry node

• 8GB RAM
• 4vCPUs
• 200GB Disk space

• Ubuntu 18.04 or higher
• Go v1.17.1
• Starport

You have two options for installing the cohod binary. First, our team will be providing releases of cohod in our github repository, please check the releases page for the latest version of cohod. Secondly, you can follow the steps below to compile coho yourself.

sudo apt update  
sudo apt install build-essential jq wget git -y

wget https://dl.google.com/go/go1.17.1.linux-amd64.tar.gz
tar -xvf go1.17.1.linux-amd64.tar.gz
sudo mv go /usr/local

Now add go to your bashrc -

echo "" >> ~/.bashrc
echo 'export GOPATH=$HOME/go' >> ~/.bashrc
echo 'export GOROOT=/usr/local/go' >> ~/.bashrc
echo 'export GOBIN=$GOPATH/bin' >> ~/.bashrc
echo 'export PATH=$PATH:/usr/local/go/bin:$GOBIN' >> ~/.bashrc

# use this new bashrc configuration
source ~/.bashrc

This command invokes curl to download the install script and pipes the output to bash to perform the installation. The starport binary is installed in /usr/local/bin.

To learn more or customize the installation process, see Starport installer docs on GitHub.

curl https://get.starport.network/starport! | bash

(Optional) Starport installation requires write permission to the /usr/local/bin/ directory. If the installation fails because you do not have write permission to /usr/local/bin/, run the following command:

curl https://get.starport.network/starport | bash

Then run this command to move the starport executable to /usr/local/bin/:

sudo mv starport /usr/local/bin/

These next steps will install the cohod binary which is used to run your chain.

# Clone the Repo
git clone https://github.com/cosmic-horizon/coho.git

# Install CoHo
cd ~/coho
starport chain build

cd ~
cohod init <your moniker> --chain-id darkmatter-1

example:

cohod init coho-tester --chain-id darkmatter-1

# replace coho-tester with your moniker

Optional It's very important that after running this command you save the seed phrase that is generated. If you do not save your phrase, you will not be able to recover this account.

cohod keys add <your validator key name>

example:

cohod keys add coho-test-wallet

# replace coho-tester-wallet with a wallet name of your choosing

curl -s https://raw.githubusercontent.com/cosmic-horizon/testnets/main/darkmatter-1/genesis.json > $HOME/.coho/config/genesis.json

cd $HOME/.coho/config/
md5sum genesis.json

# a151c16fcc833c879e305bb5c18a9f7b  genesis.json

Optional

Please refer to the Cosmos Hub documentation on validators for a general overview of running a validator. We are using the exact same validator model and software, but with slightly different parameters and other functionality specific to the Cosmic Horizon Network.
