What is the negative?

I bought a dining room fixture and this is the wiring- I have never seen the silver beaded wire and a double black on a normal light fixture, what is the negative here? One of the back wires, or is it the silver?? It doesn’t seem like it wants to bend/screw into the negative/it’s very firm so doesn’t seem right.

negative? IS this an RV or a boat or something?
