Principle behind proot, ArchLinux under proot on Android.

proot allow to do some kind of chroot without being root. I wonder what is the principle behind this. I am just looking for a short explanation of how this is achieved. The only explanation I have found is the one on the wiki page: https://wiki.archlinux.org/index.php/PRoot . Is proot just a wrapper around a virtual machine (qemu)? If yes what is the performance hit? I think a real chroot does not impede performance at all. The termux project for Android, say you can run ArchLinux within proot on Android: https://wiki.termux.com/wiki/PRoot. Is it the real ArchLinux (i.e. only available for x64 processor) or an ARM port of ArchLinux that is run? If it is the real Arch, I expected a serious performance hit (given the fact that we need to emulate the processor).

It's running the ARM port, and no proot isn't a wrapper around a virtual machine.
