mv tangle /usr/bin/
tangle --version
# tangle 1.2.10
```

**Download json**

### Create keys

```bash
# Acco
tangle key insert --base-path $HOME/.tangle/data/ \
--chain $HOME/.tangle/tangle-mainnet.json \
--scheme Sr25519 \
--suri "<SEED_ФРАЗА-12>" \
--key-type acco

# Babe
tangle key insert --base-path $HOME/.tangle/data/ \
--chain $HOME/.tangle/tangle-mainnet.json \
--scheme Sr25519 \
--suri "<SEED_ФРАЗА-12>" \
--key-type babe

# Imonline
tangle key insert --base-path $HOME/.tangle/data/ \
--chain $HOME/.tangle/tangle-mainnet.json \
--scheme Sr25519 \
--suri "<SEED_ФРАЗА-12>" \
--key-type imon

# Role
tangle key insert --base-path $HOME/.tangle/data/ \
--chain $HOME/.tangle/tangle-mainnet.json \
--scheme Ecdsa \
--suri "<SEED_ФРАЗА-12>" \
--key-type role

# Grandpa
tangle key insert --base-path $HOME/.tangle/data/ \
--chain $HOME/.tangle/tangle-mainnet.json \
--scheme Ed25519 \
--suri "<SEED_ФРАЗА-12>" \
--key-type gran

# check
ls $HOME/.tangle/data/chains/tangle-mainnet/keystore/
```

#### Create a service file

```
yourname=<name>
```

```shell
tee /etc/systemd/system/tangle.service > /dev/null << EOF

Now our node has started to synchronize. We can check our node in [telemetry](https://telemetry.polkadot.io/#list/0xea63e6ac7da8699520af7fb540470d63e48eccb33f7273d2e21a935685bf1320)

## Validator setup

After the node has synchronized, we pull out the key from our node by entering the command

```bash
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

{% hint style="warning" %}
**IMPORTANT** - save the keys located in `$HOME/.tangle/node-key` and `$HOME/.tangle/data/chains/tangle-standalone-testnet/keystore/`
{% endhint %}

* 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
