  tl:dr an app connects to the Wayland compositor (like an X server) and sends it draw commands using the Wayland protocol. The compositor accepts these connections on a Unix socket, /run/user/1000/wayland-0 by default The protocol is defined in the libwayland library. Most apps don't use libwayland directly, but their widget toolkit like GTK or Qt does it for them.

    at the risk of appearing pedantic: whereas a large chunk of X11 is dedicated to draw commands (circle here, line here, pixel here): wayland doesn't have any instead it's all shared memory buffers

      X was designed to be used over a network, where sending buffers would have been very slow. Sending primitive draw commands, on the other hand, was much faster.
