If the point is to run on arm architecture (aarch64 as @Mextro was pointing out) you can just use real arm based servers. Either cloud based or DC based would do, but something a tad more serious than a raspberry is probably a good idea.
I distribute the compiled binaries regularly here and soon on https://www.myadanode.com with tutorials.
On the raspberry point, I can’t see the benefit from a cardano network point of view ?
- It’s cheaper for sure, but cardano reward you for a reason right. Having stable and reliable node IS important ! I’m sorry to say but as much as I love raspberry I would not sit a multi billion economy on it.
- It’s fun. Yes for you as a project probably. But from the cardano point of view it’s just another arm based pool running.
- You are running them home, so you can eventually be impacted by electricity outage (it happens to all of us), internet issues (same), human and life events.
Happy to be proven wrong here, but it would need some serious arguments. And yeah I guess relays can be an option … i guess …
