Becoming a Validator

Создаем кошелек

# Create a New Key
babylond keys add wallet

или восстанавливаем прошлый

babylond keys add wallet --recover

вводим сид фразу от кошелька

идем в дискорд и запрашиваем токены

!faucet адрес кошелька

Проверка баланса:

babylond q bank balances $(babylond keys show wallet -a)

Generate a BLS Key Pair

babylond create-bls-key $(babylond keys show wallet -a)
sed -i -e "s|^key-name *=.*|key-name = \"wallet\"|" $HOME/.babylond/config/app.toml
sed -i -e "s|^timeout_commit *=.*|timeout_commit = \"10s\"|" $HOME/.babylond/config/config.toml

Рестартим и проверяем логи

sudo systemctl daemon-reload
sudo systemctl start babylond.service && sudo journalctl -u babylond.service -f --no-hostname -o cat

Create the Validator

babylond status | jq .SyncInfo

После синхронизации создаем файл validator.json

Выводим Pubkey 

babylond tendermint show-validator

Вставляем ваш Pubkey и Имя_вашего_валидатора

{
        "pubkey": {"@type":"/cosmos.crypto.ed25519.PubKey","key":"SBLBy6fLwg4TZFqTdT3muxffkTj9YlsIyPB3L8oYg="},
        "amount": "1000000ubbn",
        "chain-id": "bbn-test-3",
        "moniker": "Имя_вашего_валидатора",
        "website": "@WingsNodeTeam",
        "security": "telegramm @WingsNodeTeam",
        "details": "-_-",
        "commission-rate": "0.1",
        "commission-max-rate": "0.2",
        "commission-max-change-rate": "0.01",
        "min-self-delegation": "1"
}

Сохраняем и записываем путь к этому файлу, пример

/root/.babylond/config/validator.json

Создаем валидатора

babylond tx checkpointing create-validator /root/.babylond/config/validator.json --from=адрес_кошелька --chain-id bbn-test-3 --fees=12000ubbn -y

Ждем 1 час и проверяем валидатора в браузере

https://testnet.babylon.explorers.guru/validators

Делегировать себе

babylond tx epoching delegate адрес_валидатора 1000000ubbn --from=ваш_кошелек --chain-id bbn-test-3 --fees=12000ubbn -y
