 So if I could chip in on this for a second. Oh, yes, please. Recently, I've read a lot about Tumblebit and Mimblewimble. Yes. In those two cases, it's kind of a result of privacy that you have in this little bit because you remove data from the chain that everyone can see. That is true, actually. Mimblewimble actually delivers privacy and anonymity at a much better scale than Bitcoin. It does so at the cost of computational complexity and flexibility. So if you think of Bitcoin as here and Ethereum as much more flexible over here, Mimblewimble is in the opposite direction. All you can do is elliptic curve points. You can't even do basic Bitcoin scripting. So there is a trade-off. It's just a trade-off on a different axis. I think the same applies to Tumblebit, but I'm not sure. I'd like to see.
