Create a service file

We use the --auto-insert-keys switch to have the node automatically generate keys. If you want to create the necessary keys yourself, then go to this section

yourname=<name>

tee /etc/systemd/system/tangle.service > /dev/null << EOF
[Unit]
Description=Tangle Validator Node
After=network-online.target
StartLimitIntervalSec=0

systemctl daemon-reload
systemctl enable tangle
systemctl restart tangle && journalctl -u tangle -f -o cat

Now our node has started to synchronize. We can check our node in telemetry

Validator setup

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

If you get a similar result, then everything is great {"jsonrpc":"2.0","result":"0xa0very0long0hex0string","id":1} - copy the key (in bold) we will need it in the near future

IMPORTANT - save the keys located in $HOME/.tangle/node-key and $HOME/.tangle/data/chains/tangle-standalone-testnet/keystore/

• Go to the website and first create a stash wallet

• For stash we configure Set on-chain Identity for identification

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

Next, insert our key received from the validator node, select the commission percentage

As soon as a place among the validators becomes available, you will appear in the Staking Overview tab, but for now you can find yourself on the Waiting tab
