cd polkadot-sdk
git checkout polkadot-v1.18.7
cargo build --release

Configure and Create a Systemd Service

current_user=$(whoami)
STARTNAME="Your_Node_Name"

sudo tee /etc/systemd/system/polkadot.service > /dev/null <<EOF

Start and Enable the Service

sudo systemctl daemon-reload
sudo systemctl enable polkadot.service
sudo systemctl restart polkadot.service

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