STEP 1 - GETTING A VPS

Getting a VPS with less than 1 or 2$ is enough

• Select payment method as CryptoCurrency/Heleket and click Pay

• Go back to Virtual Private Servers under Products/Services tab

• Select a VPS (0.39$/day ,I chose DE-R9-2) and then order. (If possible, Choose higher specs for a faster contribution)

• Select Ubuntu 22.04 and Pay

• Select Personal Account and then Place an rder ☑️

• Go back to Virtual Private Servers and select your VPS name (Takes some minutes to show up)

• Click on the icon To Panel

• Change the password by clicking the 3 dots (Dont forget this password!)

IP address of our VPS is shown there. Need it to run the VPS

STEP 2 - RUNNING THE VPS

Now we’re going to set up the VPS from our local PC. Once it’s running, the process will continue on the VPS even if your PC is turned off

This is the main advantage of using a VPS

For contributing to the ETHStorage ceremony, you need to keep the terminal process on the VPS running while you are in the queue

Since the VPS is hosted in the cloud, it will stay active even if you shut down your own PC ✅

• Press Windows Key + R, type powershell, and hit Enter to open PowerShell.

Now copy and paste these commands one-by-one

Connect your VPS

ssh root@<your vps IP address>

Update and install the dependencies

sudo apt update && sudo apt upgrade -y

sudo apt install -y curl git build-essential

Installing Node.js

curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -

sudo apt install -y nodejs

sudo npm install -g [email protected]

Create temporary directory

mkdir ~/trusted-setup-tmp && cd ~/trusted-setup-tmp

Install Phase2 Cli

sudo npm install -g @p0tion/phase2cli

Authenticate with GITHUB

phase2cli auth

• Copy the link shown in your terminal or click on github.com/login/device
• Authorise your github account by the auth code shown in your powershell
• Go back to your powershell

Contributing to the ceremony

screen -S ceremony

phase2cli contribute -c ethstorage-v1-trusted-setup-ceremony

• Choose randomly on the prompt came

Final Steps

• Now wait for your queue
• When your turn comes the tool will automatically process your contribution
• Now.. You have successfully contributed to the ETHstorage V1 Trusted Setup Ceremony ✅

If the queue is showing for so many days.. dont worry.. it would still get contributed before 22nd August

Screen Session Controls

• Press Ctrl A + D (Screen detaches)

Now you can safely close the powershell and let the queue run in your VPS safely. You can even turn off your WIFI and PC.

• For re-attaching screen (open your powershell and type these commands)

  ssh root@<your vps IP address>

  screen -r ceremony

After successfull contribution remove the login permissions

  phase2cli clean

  phase2cli logout

  cd ~ && rm -rf ~/trusted-setup-tmp
