Here are the detailed steps from start to end on setting up KEEP Random Beacon Node on vultr.com VPS. It would take about ~1 hr from start to end. Potentially can take longer if you get stuck in any of the below steps.
If you already have a Ubuntu VPS(server) ready to go, skip section 1 and directly go to section 2.
Main sections of setup —
- Server setup on vultr.com setup
- MyEtherWallet setup for new ETH account
- KEEP Token Grant
- KEEP dashboard contracts
- Infura project
- Vultr.com Server setup for Random Beacon node
You would need to do all the steps to have the Random Beacon Node running.
1 —Server setup on vultr.com setup
Go to vultr.com and signup. They are offering 100$ credit for first 30 days. Signup process is pretty straightforward. Once signed into your account, follow the below steps.
1.a — After logging into account — you will be taken to the below main page. Click “Deploy Instance”.
1.b — You will be taken to Deploy Instance page. On this page, choose the below setup.
- For “Choose Server” — Leave the Choose Server to “Cloud Compute”
- For “Server Location” –Leave the Server Location to Default unless you want to be specific.
- For “Server Type” — Select the server type to UBUNTU and select 18.04 as below.
- For “Server Size” — I went with 10$ option. But you can also go with 5$ option to start with.
- For “Additional Features” — Leave it to default — all unchecked.
- For “Startup Script” — Not needed
- For “SSH Keys” — Add public key if you like to login via SSH. For this guide, I will leave it blank i.e. not setup SSH login.
Note: Vultr auto-generates the root password if you do not setup SSH.
- For “Server Hostname & Label” — I enter “KEEP-ON-VULTR”, you can enter the desired name.
- Click Deploy Now.
Give it few mints for the server to be setup.
1.c — Once the Server is deployed — go to “Products”, “Instances” tab as shown below. On Instances, click on “Server Details” as shown.
Copy the “IP address” and “Password”.
That’s the end of section 1.
2 — MyEtherWallet setup for new ETH account
2.a — Create a new Wallet — Accept the defaults and click ‘Next’ few times — then you get to the below page.
2.b — Click “By Keystore File”, enter the password and click “Next”.
2.c — Give it few moments and once the keystore file is ready, download it locally to your computer. Once downloaded, rename it to keep_wallet.json (optional).
That’s the end of section 2.
3 — KEEP Token Grant
3.a — Open the keep_wallet.json file (from 2.c) and you will get the ETH address. Add 0x to this to get your complete address as “0x436c87808eda3f52cad17f7bcd70e78cd2fa86bd”
3.b — go to https://us-central1-keep-test-f3e0.cloudfunctions.net/keep-faucet-ropsten?account=0x436c87808eda3f52cad17f7bcd70e78cd2fa86bd and get token grant.
If you successfully get a 300k token grant, you will get the below screen. If you get a token grant failed, give it sometime and keep trying. This is mandatory to proceed to next steps.
That’s the end of section 3.
4 —KEEP dashboard contracts
4.a — Import the new ETH address using json file into metamask on chrome as below.
4.b — Go-to : https://dashboard.test.keep.network/tokens and connect the newly imported ETH account from Metamask.
4.c — Delegate the KEEP tokens as below with your ETH address. Accept/Confirm the Metamask Transaction.
4.d — Go to Applications sections and authorize Contracts for tBTC. Note: It takes a while to load this page. Hang on !
Click Authorize and Accept/Confirm the Metamask Transaction — repeat for all. Add some ETH for bonding. Once done, it should look like below.
4.e — Go to Applications sections and authorize Contracts for Random Beacon. Note: It takes a while to load this page. Hang on !
Click Authorize and Accept/Confirm the Metamask Transaction. Once authorized, it should look like below.
That’s the end of section 4.
5 — Infura Project
5.a —Register at https://infura.io/register. Create a project and you can name it whatever you want.
5.b —Switch to Ropsten and copy project ID and endpoints — you will need this later. Shown below.
That’s the end of section 5.
6 — Vultr.com Server setup for Random Beacon node
Here comes the exciting part of node setup.
6.a — Login to your server through putty using the IP address, user name = root and Password generated by VULTR (step 1.c). Or if you used SSH — login to server via SSH.
Note: If you do not have putty already installed, download from here https://www.putty.org/
6.b — One of the first command I always run on new server is
sudo apt-get update
6.c — I recommend changing the default password using the below command (optional).
6.d — Add Firewall rules.
sudo ufw allow 22/tcp
sudo ufw allow 3919/tcp
sudo ufw enable
6.e — Get the Docker for your server using below commands.
sudo apt-get remove docker docker-engine docker.io
sudo apt install docker.io curl -y
sudo systemctl start docker
sudo systemctl enable docker
sudo docker –version
6.f — Setup directory structure.
mkdir -p $HOME/keep-client/config
mkdir -p $HOME/keep-client/keystore
mkdir -p $HOME/keep-client/persistence
6.g — Export the below environment variables.
export SERVER_IP=$(curl ifconfig.me)
Echo the variables to see if they are correctly set —
6.h — keystore file setup.
Copy the keep_wallet.json file contents to newly created file on server keep_wallet.json
Save and exit.
To confirm if the file is correct check with cat command,
6.i — Config file setup.
Update Infura End points (step 5.b) and ETH address (step 2.c). Rest of the things, you can copy as-is.
# Ethereum host connection info.

Note: Bootstrap peers keep changing and you might have to check in discord/github to get the latest.
6.j — Start docker using below command.
sudo docker run -dit \
--restart always \
--volume $HOME/keep-client:/mnt \
--env KEEP_ETHEREUM_PASSWORD=$KEEP_CLIENT_ETHEREUM_PASSWORD \
--env LOG_LEVEL=debug \
--name keep-client \
-p 3919:3919 \
keepnetwork/keep-client:latest --config /mnt/config/config.toml start
Note: Version v1.2.0-rc might get updated and you might have to check in discord/github to get the latest.
If something messed up during setup, you have to stop/remove and then recreate the docker.
6.k — Check if docker is running and check logs.
sudo docker ps -a
sudo docker logs keep-client -f
6.l — Check if you are connected to peers :
sudo docker logs keep-client -f | grep “peers”
If your count is more than 0, you are good and done. You have now successfully deployed your KEEP Random Beacon Node on Vultr.com, Congraultaions !!
