Auto Installation

bash <(wget -qO- https://raw.githubusercontent.com/CoinHuntersTR/props/main/AutoInstall/union.sh)

Sync Node

Node ağ ile eşleşmiş olması gerekiyor. Bunun için

uniond status 2>&1 | jq

komutunu çalıştırdığınızda false çıktısı vermesi gerekir. True çıktı alırsanız aşağıdaki adımlara devam etmeyin.

Run a Validator

cd $HOME

İlk önce Pubkeyimizi alıyoruz.

uniond comet show-validator

{"@type":"/cosmos.crypto.ed25519.PubKey","key":"0LuMdRNJpWGiH+b+................"} buna benzer bir çıktı alacaksınız.

Sonrasında validator json dosyası açıyoruz.

Aşağıdaki dosyayı kendinize göre düzenlemeyi unutmayın. Validator ismi, site linkleri vs.

cat << EOF > ~/.union/config/validator.json
{
	"pubkey": {"@type":"/cosmos.crypto.ed25519.PubKey","key":"BCDw/cq+7VxwNU/UIDc08JaYXru0Wa8SPoamzYSHfY8="},
	"amount": "1000000muno",
	"moniker": "",
	"identity": "",
	"website": "",
	"security": "",
	"details": "",
	"commission-rate": "0.1",
	"commission-max-rate": "0.2",
	"commission-max-change-rate": "0.01",
	"min-self-delegation": "1"
}
EOF

terminale yapıştırdıktan sonra, CTRL X Y enter ile çıkıyoruz.

Şimdi tekrardan node restart atalım

sudo systemctl start union-testnet.service && sudo journalctl -u union-testnet.service -f --no-hostname -o cat

Şimdi aşağıdaki komutu çalıştırıyoruz. wallet yerine kendi cüzdan isminizi yazmayı unutmayın. Terminale cüzdan kurmak için Useful Commands bölümüne bakabilirsiniz.

İlk olarak aşağıdaki komutları çalıştırıyoruz.

export PRIV_KEY=$(jq -r '.priv_key.value' ~/.union/config/priv_validator_key.json)
export POSSESSION_PROOF=$(uniond prove-possession "$PRIV_KEY")

uniond union-staking create-union-validator /root/.union/config/validator.json $POSSESSION_PROOF \
  --from wallet \
  --chain-id union-testnet-9 \
  --fees 0muno 

Sonrasında validator create komutunu çalışıtıryoruz.
