1- Where to buy VPS

The first thing that is needed to participate in Node Testnets is a VPS server

In order to buy a VPS ( Cloud Server), I introduce several good (in my opinion) providers with and without crypto payment with brief information

Rank Provider Payment Method Discription
1 Hetznr Credit card - need KYC Best Hosting , not very cheap auction servers (min. $30) are good
2 Contabo Credit card - need KYC Cheap but for a very few nodes we had bandwidth issues
3 Hostbrr Crypto Cheap to Normal pricing, good performance
4 PQhosting Crypto, You might need KYC Good performance and some cheap servers
5 Aeza Crypto Good for hourly servers, or you might findaa good server simetimes

I'm not RESPONSIBLE nor AFFILATED with any of these providers. I just used them before, and I think they are good choice. You can choose wherever you think is better

2- What system to buy

Before buying a VPS, we must consider several components to choose the required system

  • CPU: Usually, 4core to 16core
  • Ram: Usually, 4GB to 32GB
  • HDD, SSD: Projects always consider the hard disk of the Nodes to be higher than required. In few nodes such as Prover or Validator in Active-set maybe a lot of hard disk is needed. Minimum is better to be 60
  • Operating-system must be Ubuntu, Ubuntu 22 is usually compatible with every project
  • VPS must be ipv4 and must NOT be NAT

3- Let's Buy a VPS

To understand better, let's buy a server from 2 Iranian and foreign providers

This is not an advice to buy from them and I just want to show you the process

After this guide, I'm not sure if they will get out of stock of their servers, you can consider creating a ticket to ask before proceeding to buy

Hostbrr

Let's list some of their servers orders:

  • The list might be outdated, I recommend to go find yourself.

High RAM: Memory-Optimized VPS

High RAM - Better net bandwidth: RAM-Optimized - Premium

Good CPU: AMD Ryzen 9 7950XD

Good CPU - Cheaper: AMD Ryzen 9 5950X

1- I pick $14.99 VPS from AMD Ryzen 9 5950X

  • 4 vCore ,8GB RAM, 150 GB Storage can be a good choice for me

2- I register my Contact Information and pay with my metamask wallet through Coinbase Commence payment method

3- Install Ubuntu.22

  • After payment, I wait until my server to get active in services page
  • We must install ubuntu manually in Hostbrr when server is activated
