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
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
