A Companion to Ketan’s Nodebox Guide – Upgrade your Bitcoin Node

Ketan from Ministry of Nodes has created a guide on youtube to help others setup their own Bitcoin node running BTCPay Server and Lightning on a desktop PC and it was exactly a setup I had been interested in myself. I realize this is very niche subject matter but I did the work of documenting this project and thought that others might benefit from the documentation.

I plan on breaking this up into multiple parts in order to mirror Ketan’s youtube videos. There are places throughout his series where it would be helpful if you have a link or a quick copy and paste in order to be able to keep up with his instructions.

Who this isn’t for; most will do fine running a node with a single board computer, like a Raspberry Pi. If all you are doing is confirming your own transactions, occasionally spending with lightning, coinjoining, etc., then I don’t think you need an upgrade to your bitcoin node setup. The beauty of Bitcoin is that anybody can run their own node in order to verify their Bitcoin is real and not trust anyone else with their financial information, and for most a single board computer should work just fine for that.

If however you are looking to run a Lightning routing node where you expect to have a lot of traffic running through it, or if you are looking to run a public facing instance of BTCPay server, I think you should consider upgrading to a computer that is capable of handling the traffic in a more dependable way. I am differentiating here between a “Lightning Node” and a “Lightning Routing Node” on purpose. If you just plan on opening channels in order to spend, and are not so much concerned for earning routing fees and being a central point of the lightning network, then there is no reason to upgrade your node in my opinion.

I can confirm that, after going through Ketan’s guides a few times, and running this stack on a few different computers, it is very dependable and less buggy then when I have tried to run a public facing BTCPay Server on a raspberry pi. Admittedly, I have not run any of those computers where there is a lot of lightning traffic. I have not had the time with the machines to allow for that yet AND my main use case for this setup is for hosting a public facing BTCPay Server in a self-sovereign way. As always it is important to do your own research.

In Ketan’s guide he starts by recommending a dell optiplex 9020 micro for this project. At the top of this post, the picture of a PC next to a Raspiblitz is of a Dell 3060 micro, which has the same form factor as the 9020 micro. You can see it is a small machine, not much bigger than my Raspiblitz, but the difference in capability and dependability is big. I cannot recommend the 3060 because it requires a windows installation in order to boot. Edit: Using these instructions, I was able to get the 3060 micro to boot to ubuntu server without a windows installation on the computer. The video describes installing ubuntu, not ubuntu server, but just swap in the ubuntu server .iso instead and follow the rest of those instructions if you want to go with a newer machine than the 9020 micro.

Here is an affiliate link to Amazon selling a Dell 9020.

Here is an affiliate link to a 1TB Samsung SSD that is about as low-cost as they get for a Samsung stick.

Here is an affiliate link to a 1TB Samsung Pro SSD stick that is encased in a heatsink. I went with this version because I like to work to keep temperatures in a sweet-spot and this SSD is what will be constantly writing information in high traffic environments.

A few points to keep in mind:

  • If you are going to get one of the 9020 micros, keep in mind that they are not new machines, so get one that has some sort of warranty.
  • If you can get it without an SSD, that is preferable since it is best to put a Samsung M.2 SSD into it.
  • Get one that has a single stick of 8gb RAM, not two sticks of 4gb so that you can upgrade to 16gb of RAM if you want to.
  • Be aware that the Dell 9020 also refers to bigger machines which may not have an M.2 ssd slot, which is a critical part to the dependability of this setup. The one being recommended for a Node Upgrade is the Dell 9020 Micro.
  • If you don’t care about using a bigger machine for this, then it doesn’t really matter what kind you use. You could scale this up to a much larger, higher performing machine if you intend to use in a more industrial-like way.
