• After launch, we wait for our node to synchronize. You can track our condition using telemetry

TELEMETRY

• After the node has synchronized, we pull out the key from our node by entering the command

curl -H "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "author_rotateKeys", "params":[]}' http://localhost:9933

Creating a validator

• Go to the chain and first create a wallet

• We create a validator. To do this, select Network - Staking - Accounts - Validator
