- Go v1.17.1
- Starport
Install CoHo, Generate Wallet and Start your Node
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.
Install Go version 1.17.1
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
Install Starport
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/
Build CoHo
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
Generating your wallet and starting CoHo instance
Initiate CoHo Instance
cd ~
cohod init <your moniker> --chain-id darkmatter-1
example:
cohod init coho-tester --chain-id darkmatter-1
# replace coho-tester with your moniker
Create Validator Key
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
Downloading Genesis
curl -s https://raw.githubusercontent.com/cosmic-horizon/testnets/main/darkmatter-1/genesis.json > $HOME/.coho/config/genesis.json
Verify Genesis
cd $HOME/.coho/config/
md5sum genesis.json
# a151c16fcc833c879e305bb5c18a9f7b genesis.json
Create a Validator
Optional
Please see the create-a-validator docs
Start your node
cohod start
More about validators
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.
