Speaking of mobile versions, is there the possibility of setting up a Bitcoin node on a mobile device (Android/iOS)?
Which OS do you prefer? For iOS you could use 'Fully Noded' from the app-store. (

This app is a bitcoin wallet which is completely powered by ur own node via tor. But its not a full node by itself, it 'just' interfaces with ur own personal node. Not sure if you are looking for thus.
Even though mobile devices are getting more and more memory and power, you simply can't compare it to a desktop or a server running a node, especially in terms of capacity, processing power or the connectivity to the network which are all important things for running a node successfully.
I just checked again to see if there might be an option on Android devices. In fact, there should be project ABCore (
https://github.com/greenaddress/abcore), which allows you to run a full node on an Android device. But I have zero knowledge with this system - might be worth to look into dat.
