Install Union Validator (testnet-9) di Ubuntu

1. Update paket dan install build tools

apt update

apt install curl git jq lz4 build-essential -y

apt upgrade -y

2. Install GO

sudo rm -rf /usr/local/go

curl -Ls https://go.dev/dl/go1.22.3.linux-amd64.tar.gz | sudo tar -xzf - -C /usr/local

eval $(echo 'export PATH=$PATH:/usr/local/go/bin' | sudo tee /etc/profile.d/golang.sh)

eval $(echo 'export PATH=$PATH:$HOME/go/bin' | tee -a $HOME/.profile)

3. Download binaries union

mkdir -p $HOME/.union/cosmovisor/genesis/bin

wget -O $HOME/.union/cosmovisor/genesis/bin/uniond https://snapshots.kjnodes.com/union-testnet/uniond-v0.25.0-linux-amd64

chmod +x $HOME/.union/cosmovisor/genesis/bin/uniond

ln -s $HOME/.union/cosmovisor/genesis $HOME/.union/cosmovisor/current -f

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

4. Install Cosmovisor

go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@v1.6.0

5. Create service union (systemd)

sudo tee /etc/systemd/system/union-testnet.service > /dev/null << EOF
[Unit]
Description=union node service
After=network-online.target

[Service]
User=$USER
ExecStart=$(which cosmovisor) run start --home=$HOME/.union
Restart=on-failure
RestartSec=10
LimitNOFILE=65535
Environment="DAEMON_HOME=$HOME/.union"
Environment="DAEMON_NAME=uniond"
Environment="UNSAFE_SKIP_BACKUP=true"
Environment="PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:$HOME/.union/cosmovisor/current/bin"

[Install]
WantedBy=multi-user.target
EOF

systemctl daemon-reload

systemctl enable union-testnet.service

6. Inisialisasi node

• Workaround mandatory home argument

alias uniond='uniond --home=$HOME/.union/'

• Set node configuration

uniond config set client chain-id union-testnet-9

uniond config set client keyring-backend test

uniond config set client node tcp://localhost:17157

• Initialize the node (ubah VALIDATOR-NAME menjadi nama validator anda)

MONIKER="VALIDATOR-NAME"

uniond init $MONIKER --chain-id union-testnet-9 --home=$HOME/.union

• Download genesis and addrbook

curl -Ls https://raw.githubusercontent.com/CoinHuntersTR/props/refs/heads/main/union/genesis.json > $HOME/.union/config/genesis.json

curl -Ls https://raw.githubusercontent.com/CoinHuntersTR/props/refs/heads/main/union/addrbook.json > $HOME/.union/config/addrbook.json

• Add seeds

sed -i -e "s|^seeds *=.*|seeds = \"3f472746f46493309650e5a033076689996c8881@union-testnet.rpc.kjnodes.com:17159\"|" $HOME/.union/config/config.toml

• Set minimum gas price

sed -i -e "s|^minimum-gas-prices *=.*|minimum-gas-prices = \"0muno\"|" $HOME/.union/config/app.toml

• Set pruning

sed -i \
  -e 's|^pruning *=.*|pruning = "custom"|' \
  -e 's|^pruning-keep-recent *=.*|pruning-keep-recent = "100"|' \
  -e 's|^pruning-keep-every *=.*|pruning-keep-every = "0"|' \
  -e 's|^pruning-interval *=.*|pruning-interval = "19"|' \
  $HOME/.union/config/app.toml

• Set custom ports

sed -i -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:17158\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:17157\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:17160\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:17156\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":17166\"%" $HOME/.union/config/config.toml

sed -i -e "s%^address = \"tcp://0.0.0.0:1317\"%address = \"tcp://0.0.0.0:17117\"%; s%^address = \":8080\"%address = \":17180\"%; s%^address = \"0.0.0.0:9090\"%address = \"0.0.0.0:17190\"%; s%^address = \"0.0.0.0:9091\"%address = \"0.0.0.0:17191\"%; s%:8545%:17145%; s%:8546%:17146%; s%:6065%:17165%" $HOME/.union/config/app.toml

7. Buat key/Wallet (Simpan dan import mnemonic anda ke keplr)

uniond keys add wallet

8. Claim faucet (konekkan wallet dan kumpulkan faucet minimal 1.2)
   app.union.build
   Add RPC union (UNO)

9. Download latest chain snapshot

curl -L https://snapshots.coinhunterstr.com/testnet/union/snapshot_latest.tar.lz4 | tar -Ilz4 -xf - -C $HOME/.union

[[ -f $HOME/.union/data/upgrade-info.json ]] && cp $HOME/.union/data/upgrade-info.json $HOME/.union/cosmovisor/genesis/upgrade-info.json

10. Start service

systemctl start union-testnet

11. Cek logs (Jangan lanjut ke step ke 12 pastikan dulu block terbaru sama dengan yg di vps anda)

journalctl -u union-testnet.service -f --no-hostname -o cat

• Cek block/height terbaru di explorer

12. Run Validator

• Cek pubkey validator anda (contoh hasil {“@type”:“/cosmos.crypto.ed25519.PubKey”,“key”:“0LuMdRNJpWGiH+b+…”})

uniond comet show-validator

• Edit yang di perlukan sebelum paste ke vps (pubkey, moniker dan website)

cat << EOF > ~/.union/config/validator.json
{
  "pubkey": {"hapus-ubah-punya-bro-@type":"/cosmos.crypto.ed25519.PubKey","key":"BCDw/cq.....zYSHfY8="},
  "amount": "1000000muno",
  "moniker": "VALIDATOR-NAME",
  "website": "https://websiteanda.com",
  "commission-rate": "0.1",
  "commission-max-rate": "0.2",
  "commission-max-change-rate": "0.01",
  "min-self-delegation": "1"
}
EOF

• Start service lagi

systemctl start union-testnet.service

• Export config

export PRIV_KEY=$(jq -r '.priv_key.value' ~/.union/config/priv_validator_key.json)

export POSSESSION_PROOF=$(uniond prove-possession "$PRIV_KEY")

• Create validator

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

13. Cek validator anda
    explorer.testnet-9.union.build/union/staking
