Set Vars

Moniker yerine validator adınızı ekliyoruz.

junctiond config chain-id junction
junctiond init "Moniker" --chain-id junction

Config init app

wardend init $MONIKER
sed -i -e "s|^node *=.*|node = \"tcp://localhost:${WARDEN_PORT}657\"|" $HOME/.warden/config/client.toml

Download Genesis and Addrbook

sudo wget -O $HOME/.junction/config/genesis.json https://raw.githubusercontent.com/CoinHuntersTR/props/main/Airchains/genesis.json

Snapshot

Stop the service and reset the data 

sudo systemctl stop junctiond
cp $HOME/.junction/data/priv_validator_state.json $HOME/.junction/priv_validator_state.json.backup
rm -rf $HOME/.junction/data

Download latest snapshot 

curl -L https://snapshots.coinhunterstr.com/data.tar.lz4 | lz4 -dc - | tar -xf - -C $HOME/.junction
mv $HOME/.junction/priv_validator_state.json.backup $HOME/.junction/data/priv_validator_state.json

Restart the service and check the log 

sudo systemctl start junctiond && sudo journalctl -u junctiond -f --no-hostname -o cat

Automatic Installation

Moniker yerine Validator isminizi yazıp enter basın.

wget -q -O Airchains.sh https://raw.githubusercontent.com/CoinHuntersTR/props/main/AutoInstall/Airchains.sh && chmod +x Airchains.sh && ./Airchains.sh

Sync Node

Node ağ ile eşleşmiş olması gerekiyor. Bunun için junctiond status 2>&1 | jq komutunu çalıştırdığınızda false çıktısı vermesi gerekir. True çıktı alırsanız aşağıdaki adımlara devam etmeyin.

Run a Validator

İlk önce Pubkeyimizi alıyoruz.

junctiond comet show-validator

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

cd $HOME

Sonrasında validator json dosyası açıyoruz.

nano /root/validator.json

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

{
	"pubkey": <validator-pub-key>,
	"amount": "9900000amf",
	"moniker": "<validator-name>",
	"identity": "optional identity signature (ex. UPort or Keybase)",
	"website": "validator's (optional) website",
	"security": "validator's (optional) security contact email",
	"details": "validator's (optional) details",
	"commission-rate": "0.1",
	"commission-max-rate": "0.2",
	"commission-max-change-rate": "0.01",
	"min-self-delegation": "1"
}

terminale yapıştırdıktan sonra, CTRL X Y enter ile çıkıyoruz.

Şimdi tekrardan node restart atalım

sudo systemctl restart junctiond

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

junctiond tx staking create-validator $HOME/validator.json --from wallet --chain-id junction --fees 5000amf
