You can stop seeing the logs with CTRL+C !
tip
If your node is not syncing , try these commands to change the peers configuration and check which one is working correctly .
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"7ebc08bbef4bd2b4da8d881474710a2500854c2b@airchain-t-rpc.noders.services:31656\"/" ~/.junction/config/config.toml

warning
Before continuing the process you have to wait about 48hr for your node to be synced then continue the process!
Run the Command to check the status of the Node.
junctiond status
warning
Should the 'catching_up' field return 'true', it's important to wait until the Node completes its synchronization. Do not proceed with further steps until this process is finished.
Creating New Account for the Validator
junctiond keys add <validator-name>
Fund you Account
You need to ensure that your validator account holds a minimum of 58 tokens . If your account doesn't have enough tokens, you can acquire testnet tokens from our discord faucet channel. The faucet is accessible at Airchains Faucet.
Stake Token to become a Validator
Before executing the command junctiond tx staking create-validator path/to/validator.json --from keyname, you need to create a validator.json file with the following details. Below is an example:
To obtain the pubkey, you can use the command:
junctiond comet show-validator
The output will be something like this:
{"@type":"/cosmos.crypto.ed25519.PubKey","key":"ZXONS7NNjLWH4HePBOoHKDAYeLXQO5iUwpCRQSi1poI="}
You'll need to paste the pubkey value into the pubkey section of the JSON file.
note
Please adjust the staking amount and other keys as you see fit.
{
"pubkey": <validator-pub-key>,
"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",

}
junctiond tx staking create-validator path/to/validator.json --from <key-name> --chain-id junction --fees 500amf
note
A prompt will appear in the CLI. To proceed, type 'y' and press enter.
It will return Transaction hash Like this
code: 0
codespace: ""
data: ""
events: []
gas_used: "0"
gas_wanted: "0"
height: "0"

Query Validator Set
To See if you were accepted as a validator,
junctiond query tendermint-validator-set
note
If your address is visible, it indicates successful inclusion in the validator set. Please note that this process may take some time.
