Start

systemctl daemon-reload
systemctl enable tangle
systemctl restart tangle && journalctl -fu tangle -o cat

• 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

BACKUP

🟢 save the located keys in $HOME/.tangle/node-key and $HOME/.tangle/data/validator/YOURNAME/chains/tangle-testnet/keystore/

Creating a validator

• Go to the website and first create a wallet

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

logs

journalctl -fu tangle -o cat

restart

systemctl restart tangle && journalctl -fu tangle -o cat

delete node

systemctl stop tangle &&
systemctl disable tangle &&
rm /etc/systemd/system/tangle.service &&
systemctl daemon-reload &&
cd
rm -r .tangle
