Run a Protocol node
With the Archway node in place and the KYVE node also installed you can finally start the protocol node.
Start Node
Finally the protocol validator can be started. In order to start it, execute the following command. Since we named our valaccount archway we select the this valaccount to start the KYSOR.
./kysor start --valaccount 'archway'
You can also start the process in debug mode by adding the --debug flag like this:
./kysor start --valaccount 'archway' --debug
If you're running the Archway node on a separate machine you have to tell the protocol validator with an env variable the new rpc endpoint.
Create .env file:
KYVEJS_TENDERMINT_RPC="https://my-custom-rpc-endpoint:26657"
pass it to KYSOR:
./kysor start --valaccount 'archway' --env-file="path/to/.env"
After the node successfully started you should see the following logs:

2023-02-13 08:46:00.876 INFO Visit https://app.kyve.network and join the pool from your validator account:
2023-02-13 08:46:00.876 INFO Valaddress: kyve1887l27uwn5r6u9gxw7dg9wt0kqh7uk23suumzc
2023-02-13 08:46:00.876 INFO Valname: causal-chocolate-sparrow
2023-02-13 08:46:00.876 INFO The node will not continue until the account is authorized
With this information (Valaddress and Valname) you can head over the KYVE app and join the pool.
Now that the node is already running it just needs the authorization from it's main validator account in order to run for this validator and generate rewards. For that visit your validator page and click on Join existing pool.
A dialog should open where you should select the pool you want to join (here Archway). After that enter the valaddress that needs to be authorized and the valname, which just serves as a security that the node has actually been started. (If you join a pool without having the node running you are in danger of receiving a timeout slash because once you join a pool you are expected to validate and upload data).
For the last option you can do a one time transfer so that the valaccount has some $KYVE to pay for transaction fees. We would recommend sending 100 $KYVE for the start which typically lasts for about 1 month.
IMPORTANT: Make sure that the valaccount always has enough $KYVE to pay for transaction fees, otherwise you are again in danger of receiving a timeout slash.
Once you have joined the pool the node should continue in about ~10 seconds. After that you are successfully participating in a pool.
Start node with systemd
If you want to start the nodes as a background process you can use systemd.
For the daemon service root-privileges are required during the setup. Create a service file. $USER is the Linux user which runs the process. Replace it before you copy the command.
Since the KYSOR can run on multiple pools on one machine we would recommend naming the daemon service after the valaccount name and with a d appending to it. With that you can create multiple service files and control each of them. This example shows the service file for our valaccount archway
You might have to execute this command with sudo
tee <<EOF > /dev/null /etc/systemd/system/archwayd.service
[Unit]
Description=KYVE Protocol-Node archway daemon
After=network-online.target
[Service]
User=$USER
ExecStart=/home/$USER/kysor start --valaccount archway
Restart=on-failure
RestartSec=3
LimitNOFILE=infinity
EOF
Don't forget to change the filename and the valaccount in the service file if you join a different pool
Start the daemon
sudo systemctl enable archway
sudo systemctl start archway
It can be stopped using
sudo systemctl stop archway
You can see its logs with
sudo journalctl -u archway -f -o cat
Start node on multiple pools
This step is optional, but the more pools you participate in the higher the rewards. If you want to join another pool just repeat the previous steps (Install pool binaries). For that you have to create a new valaccount, because a valaccount can only run on one data pool. Once you have setup the second valaccount you can start it. You can see all the pools you are participating in your validator page.
WARNING: Joining for example a second pool might double your rewards, but it also doubles the danger of getting slashed.
