I am in the EU. I want to help make the TOR network more robust by contributing a relay node. I have one of three hardware options: a raspberry pi zero W, raspberry pi 4B, or ThinkPad T470s.
In your practical experience, which of these computers would be the best for the network? As I understand, beyond a point, the CPU power doesn’t matter unless massive traffic loads go through the node.
P.S: Not sure if this is relevant, but I currently have a pihole hosted in a separate RPI zero. I plan to host this at home. I do not have a separate connection line. My router doesn’t support vlan.
Add: Thank you for the kind replies. Based on the feedback, it think I’m currently not setup to help the network. I will instead continue with my annual contribution.
I will look into hosting a node on a VPS and just pay a monthly subscription fee or something.

If you do end up hosting on a VPS, consider one with renewable energy since tor nodes can consume a lot of power over time - or for home setups, you could run it off a portable power station to offset electricity costs (check out power station comparisons to find the best wh value for continous loads).
Tor operator here.
If you don’t have a second IP for your relay, don’t host at home. You will have CAPTCHAs everywhere, many sites will block you and your ISP will eventually contact you to stop degrading their IP space reputation.
Most website owners don’t discriminate between Tor exits and relays. They subscribe to block-lists that include all known Tor IP addresses. Major online services will make your browsing experience really shitty and once you’re a “known Tor IP” it will take months to remove that reputation.
You can run a Bridge instead, but you will eventually have the same problem.
Could you route through a VPN like Torguard or something?
I have tried hosting a Tor relay on a VPS in the past and it was bottlenecked by the CPU at barely 20MB/s, although to be fair this was without hardware AES. More importantly for you, the server’s IP started getting DDoSed constantly and a whole bunch of big internet services just immediately blocked the address (the list of relay IPs is public and many things just block every address on that list instead of only exit nodes). So any of your machines are probably at least somewhat up to the task (ideally if they have hardware AES support), but this is definitely not something I’d do on my home network.
For the Tor operators, how to you mitigate the risks associated with what’s being trafficked across your network?
- simply don’t run an exit node (from home)
- run you relay no mether the type of a cheap vps that’s tor friendly
