      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.

      Six. Orders. Of. Magnitude. Keep telling yourself those differences account for that discrepancy.
