sudo rm -rvf /usr/local/go/
wget https://golang.org/dl/go1.22.4.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.22.4.linux-amd64.tar.gz
rm go1.22.4.linux-amd64.tar.gz

Put PATH to ~/.profile

nano .profile

export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin

Use source ~/.profile

source .profile

Check go

go version

Install packages

sudo apt-get update
sudo apt-get upgrade
sudo apt install mc btop nano screen git make build-essential

Binary building

Clone source from repo

git clone https://github.com/olimdzhon/sputnik.git

Open source directory

cd sputnik

Build binary

make install

Network launch

Init

sputnikd init "<moniker-name>" --chain-id dvs-4.5

Set minimum-gas-prices = "" in app.toml to minimum-gas-prices = "0.25usignal"

sed -i -e "s|^minimum-gas-prices *=.*|minimum-gas-prices = \"0.25usignal\"|" $HOME/.sputnik/config/app.toml

Generate keys

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

or

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

or

# Add keys using ledger
sputnikd keys show <key-name> --ledger

Check your key:

# Query the keystore for your public address
sputnikd keys show <key-name> -a

Create account to genesis

sputnikd genesis add-genesis-account <key-name> 10000000usignal

Create GenTX

# Create the gentx.
# Note, your gentx will be rejected if you use any amount greater than 1000000usignal.
# Make sure that all participants built their gentx files without typos.

sputnikd genesis gentx <key-name> 1000000usignal \
  --pubkey=$(sputnikd tendermint show-validator) \
  --chain-id=dvs-4.5 \
  --moniker="my-moniker" \
  --commission-rate="0.10" \
  --commission-max-rate="0.20" \
  --commission-max-change-rate="0.01"

Add all accounts to genesis

# Add account addresses of all participants before generating genesis.
# (whose Gentx files you're using to generate genesis)
sputnikd genesis add-genesis-account <account-address> 1000000usignal

Generate genesis

sputnikd genesis collect-gentxs
