Manual Installation

# Come up with the name of your node and replace it instead <your_moniker>
MONIKER=<your_moniker>

# Download binary files
cd $HOME
rm -rf juno
git clone https://github.com/CosmosContracts/juno juno
cd juno
git checkout v29.0.0
make install

# Set node configuration
junod config set client chain-id juno-1
junod config set client keyring-backend file
junod config set client node tcp://localhost:26657

# Initialize the node
junod init $MONIKER --chain-id=juno-1

# Download genesis and addrbook

Set custom ports

You can change value CUSTOM_PORT=165 To any other ports

CUSTOM_PORT=165

#"catching_up": false means that the node is synchronized, we are waiting for complete synchronization

Wallets

# Create wallet
junod keys add wallet

The wallet has been created. In the last line there will be a phrase that must be written down

# If the wallet was already there, restore it
junod keys add wallet --recover

# Insert the seed phrase from your wallet
# If everything is correct, you will see your wallet data

Validator

Do not forget to create a profile on https://keybase.io/ and set a profile photo there that will be imported by key and used for your validators.
