Требования к серверу

Recommended 4CPU 32RAM 1000GB

как вариант заказать здесь https://powervps.net/ru/?from=91820

удалить старую версию

sudo systemctl stop babylond && sudo systemctl disable babylond && sudo rm /etc/systemd/system/babylond.service && sudo systemctl daemon-reload && rm -rf $HOME/.babylond && rm -rf babylon && sudo rm -rf $(which babylond) 

Обновление пакетов сервера и подготовка к развертыванию ноды

sudo apt update && sudo apt upgrade -y

Setup Validator Name First change “Имя вашего валидатора” to your chosen validator moniker and enter this command:

MONIKER="Имя_вашего_валидатора"

Install Dependencies & Install GO Install Build Tools

sudo apt -qy install curl git jq lz4 build-essential

Install GO

ver="1.22.0"
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm "go$ver.linux-amd64.tar.gz"

Download And Build Binaries

# Clone project repository
cd $HOME
rm -rf babylon
git clone https://github.com/babylonchain/babylon.git
cd babylon
git checkout v0.8.3

# Build binaries
make build

# Prepare binaries for Cosmovisor
mkdir -p ~/.babylond
mkdir -p ~/.babylond/cosmovisor
mkdir -p ~/.babylond/cosmovisor/genesis

sudo ln -s $HOME/.babylond/cosmovisor/current/bin/babylond /usr/local/bin/babylond -f

Set Up Cosmovisor And Create The Corresponding Service

# Download and install Cosmovisor
go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@latest

# Create and start service
sudo tee /etc/systemd/system/babylond.service > /dev/null <<EOF

tar -xjf genesis.tar.bz2 && rm genesis.tar.bz2
mv genesis.json ~/.babylond/config/genesis.json

Start Service And Check The Logs

sudo systemctl restart babylond.service && sudo journalctl -u babylond.service -f --no-hostname -o cat

Becoming a Validator

# Create a New Key
babylond keys add wallet

или восстанавливаем прошлый

babylond keys add wallet --recover

вводим сид фразу от кошелька

Obtain Funds from the Babylon Testnet Faucet

идем в дискорд и запрашиываем токены

!faucet адрес кошелька

You can check your wallet balance using this command:

проверяем их на кошельке

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

Ensure that you have successfully received 1,100,000 ubbn. Please be aware that you can only claim 1 BBN from the faucet every 24 hours.

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

{
        "pubkey": {"@type":"/cosmos.crypto.ed25519.PubKey","key":"SBLBy6fLwg4TZFqTdT3muxffkTj9YlsIyPB3L8oYg="},
        "amount": "1000000ubbn",
        "chain-id": "bbn-test-3",
        "moniker": "Ваш_моникер",
        "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"
}

где, pubkey можно узнать командой

babylond tendermint show-validator

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
