      Bitcoin consumes 4,000,000,000 W of power to process four transactions per second. A single Raspberry Pi with a database can do an order of magnitude more on 5W. Think about that next time you wonder if it's a good design.

      Please point out a network protocol that requires "layers" to scale up. Last I checked SMTP, HTTP, XMPP, etc. have no problem scaling linearly with user count without requiring new "layered" protocols on top to fix underlying design flaws. We added a layer (TLS) for security.

      Yes, they're are layers, but they aren't a patch for scalability. They each serve a specific function. We add new layers to add features and reach the complete product, not to fix scalability problems in the underlying layers.

      And of course increasing the block size doesn't work either. You need a new protocol with a fundamentally scalable design.

      The "whatever it takes" mentality is what got us here. There's a limit to "whatever it takes". The current status quo is a horrendous waste of electricity. It is *not* worth it. It might be useful as a short term experiment but it is not sustainable.

      Loading seems to be taking a while.
