Yeah, you're wrong and I have a feeling that you want to stay that way because looking at your notes tells me that you just hate Bitcoin.

If you want to know how computer network protocols scale (all of them) then look at the internet. It couldn't scale at its base layer so it needed a second layer and a third, and so on. We are at 7 layers now.

But, again, I suspect you are just here to hate bitcoin and I further suspect that you're just a fucking shitcoiner so fuck straight off.
