Fulcrum > electrs.
Compiling electrs by following steps on: https://github.com/romanz/electrs/blob/v0.10.6/doc/install.md
But instead of doing it on the NUC, I'm doing it on a virtual machine, installed with the same Debian .iso file that I used on the usb stick for the NUC. I'm doing this with UTM: https://mac.getutm.app
This way I can just copy over only electrs and don't need all the mess of packages required to build it on the NUC. It would have been great if I could do this with nodejs/npm stuff too but I don’t think that’s possible.
Discussion
I haven’t heard about this one, is it compatible with Mempool blockchain explorer?
It is. But just noticed this. Seems nostr:npub18d4r6wanxkyrdfjdrjqzj2ukua5cas669ew2g5w7lf4a8te7awzqey6lt3 is running electrs so that might be the better choice if mempool space is your primary concern vs a performant wallet or other software you want to connect to your electrum server. There may be other factors to consider too.
I tend to say "dont fix it if it aint broke" but dont heed my own advice 
🤦♂️ thats their own fork of electrs, but still they forked electrs and not fulcrum
