 You mentioned layer technologies. At Bitcoin with layer one, you mentioned layer two might be a lightning network. Yes. Have you thought about further? No. To repeat the question, I mentioned layer technology, so at Bitcoin is layer one or layer zero, wikis. It's layer zero. And layer one is lightning network, what's layer two? Have I thought about other layers? It's really difficult to see how the layers involve, and what the interfaces between the layers are, and which functions end up in which layers. And keep in mind that there will be more than one stack above IP. There were multiple transmission-controlled stacks, including the OSI layer. And below IP, there were multiple stacks underneath that most people never see. So software-defined networking, and before that, fiber networks, etc. So it's impossible to know exactly how it's going to play out. What I can tell you is the protocols are not built monolithically. We're not going to do everything in a single layer. That doesn't make sense from an architecture perspective. That doesn't mean we don't scale Bitcoin, we will scale Bitcoin. But we will scale it so that the layers above it scale even further. Not because we want to do everything in a single layer. It doesn't make sense to do everything in a single layer. It doesn't work.
