It used to be a thing to use an old Android device for this purpose.
Given the size of the blockchain, and additional space needed for indexing, to run a full archival node plus Electrum server (plus OS) is gonna take at least 1TB space. 2TB would be prudent to accommodate additional growth.
If you just run a pruned node, then space won’t be an issue, but it also means you can’t look up old transactions.
I have other solutions for the space issue in mind :)
pretty sure my motorola g51 could run bitcoin core if i use my otg+charge cable with power and a 1tb SSD on it... since usb-c, you will find it hard to find these things, used to be normal, now, nope... they usually have a usb-A and usb-C and the C is for power and the A is for whatever, hub, hard drive, etc (i use mine to get ethernet and no radio internet)
i think it would be annoying to try and get it to have an inbound connection, maybe a wireguard network would enable this, with the right configuration setting to bind to the port on the wg address, idk
they keep changing android and it gets more and more complicated to do these knids of things these days
Assume the storage bit is solved. Something like a pruned node (sort of).
Seems the connection details are the potential hurdle.
not really, if you don't need it to run an RPC, and probably there is other ways around this if you are running LXC in android, to link it up somehow, worst case maybe SSH reverse tunnel
but it's been since like version 5 or so since i tried to do much linux on an android device, the restrictions are probably completely nuts by now
ah yeah, see, you could set one up with its outbound connection to one of your other nodes and it could at least serve as an IBD source
honestly though, i'd sooner trust an rPi5 to do this than an android device, and probably save money
