5. Create or import wallet
5.1. Add wallet key
You have 2 option:
5.1.1. Add new wallet key
junctiond keys add wallet
With "wallet" is your wallet name. To easy follow this guide, keep it if you don't want to change.
Important: Save this seed, if you lost it, you can't recovery your wallet
5.1.2. Recover existing wallet key
junctiond keys add wallet --recover
5.2. List all keys
junctiond keys list
5.3. Query wallet balance
junctiond q bank balances $(junctiond keys show wallet -a)
With "wallet" is your wallet name create or recovery at 5.1. Add New Wallet Key or #5.2. Recover existing key.
6. Check sync status
If it show "false", it mean no need to wait node sync data or node is synced
If it show "true", please wait it some minute (because near to recreate snapshoot - about 6 hour). After status is synced (false) you can go to next step. Please be patient, sync time will depend on your server configuration and network speed.
junctiond status 2>&1 | jq .sync_info
7. Create Validator
7.1. Obtain your validator public key
Running this command to show your validator public key
junctiond comet show-validator
The output will be same to this but with a different key:
{"@type":"/cosmos.crypto.ed25519.PubKey","key":"_**uyeP+tevNbAm+NYH5pdLfhYnGZyh3hBHD8nGpC2sI14=**_"}
7.2. Prepair validator information
Create a file named validator.json in $HOME by command**:**
nano $HOME/validator.json
Change your info, include pubkey, moniker, indentity, website, security, details and Save them
- Moniker*: Your validator name (node name) - Required
- Identiry: Your keybase.io ID (64-bit)
- Website: Your website (if you have)
- Security: Normaly is your email
- Details: Your slogan to show in validator page
{
"pubkey": {"@type":"/cosmos.crypto.ed25519.PubKey","key":"uyeP+tevNbAm+NYH5pdLfhYnGZyh3hBHD8nGpC2sI14="},
"amount": "1000000amf",
"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"
}
7.3. Create validator
Submit the transaction to create the validator:
junctiond tx staking create-validator validator.json --from wallet --chain-id junction --fees 5000amf -y
When command complete, you should copy TXHash and check transactions at https://explorer.anonid.top/airchains/tx (copy hash to find or paste it after click to search icon and press Enter) to verify this transactions is success or failed and then check your validator name in staking page of explorer at https://explorer.anonid.top/airchains/staking. Remember check in Inactive tab, because at now, only 100 top validator can be show in Active tab.
7.4. Faucet
Join Airchains Discord server at https://discord.gg/airchains
Make verify and then go to this channel and paste your wallet address at 5.2. List all keys to get your faucet https://discord.com/channels/1116269224449548359/1238910689188511835
7.5. Delegate token to your own validator
junctiond tx staking delegate $(junctiond keys show wallet --bech val -a) 1000000amf
--from wallet --chain-id junction --fees 5000amf -y
With "wallet" is your wallet name create or recovery at 5.1. Add New Wallet Key or #5.2. Recover existing key.
8. Withdraw rewards and commission from your validator
junctiond tx distribution withdraw-rewards $(junctiond keys show wallet --bech val -a) --from wallet --chain-id junction --fees 5000amf -y
9. Unjail validator
junctiond tx slashing unjail --from wallet --chain-id junction --fees 5000amf -y
10. Services Management
10.1. Reload service
sudo systemctl daemon-reload
10.2. Enable service
sudo systemctl enable junctiond10.3. Disable service
sudo systemctl disable junctiond
10.4. Start service
sudo service junctiond start
10.5. Stop service
sudo service junctiond stop
10.6. Restart service
sudo service junctiond restart
10.7. Check service status
sudo systemctl junctiond status
10.8. Check service logs
sudo journalctl -u junctiond -f --no-hostname -o cat
11. Backup Validator - Important
cat $HOME/.junction/config/priv_validator_key.json
Copy and store your node information in safe location.
12. Remove node
Make sure you want to remove node, keep seed pharse at Add wallet key and validator information at Backup validator. Once deleted, it cannot be restored
sudo service junctiond stop
sudo systemctl disable junctiond
rm -rf /etc/systemd/system/junctiond.service
sudo systemctl daemon-reload
sudo rm -f $(which junctiond)
sudo rm -rf $HOME/.junction
13. Snapshot
sudo service junctiond stop
mv $HOME/.junction/data/priv_validator_state.json $HOME/.junction/priv_validator_state.json.backup
rm -rf $HOME/.junction/data $HOME/.junction/wasmPath
wget -O- https://snap.anonid.top/snaps%2Fairchains.snap.tar.lz4 | tar -Ilz4 -xf - -C $HOME/.junction
mv $HOME/.junction/priv_validator_state.json.backup $HOME/.junction/data/priv_validator_state.json
sudo service junctiond restart && sudo journalctl -u junctiond -f --no-hostname -o cat
14. State Sync
sudo service junctiond stop
cp $HOME/.junction/data/priv_validator_state.json $HOME/.junction/priv_validator_state.json.backup
junctiond tendermint unsafe-reset-all --home $HOME/.junction
