Clone and Build Polkadot SDK

cd ~
git clone https://github.com/paritytech/polkadot-sdk.git
cd polkadot-sdk
git checkout polkadot-v1.19.2
cargo build --release

Install binaries into the system directory

sudo mkdir -p /usr/lib/polkadot
sudo cp target/release/polkadot* /usr/lib/polkadot/
sudo ln -sf /usr/lib/polkadot/polkadot /usr/local/bin/polkadot

Create working directory

mkdir -p $HOME/.polkadot
chown -R $(id -u):$(id -g) $HOME/.polkadot

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
sudo journalctl -u polkadot.service -f

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
