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.

And to all the inevitable "but decentralized but instant but global but whatever" repliers: if you think any of those require and are worth a NINE ORDER OF MAGNITUDE overhead, please never be an engineer.

Wait, how can you even compare bitcoin (technically Blockchain); a computing/transactional concept; to an actual physical device? This doesn’t even make sense to me.

Think of it as all the physical devices mining Bitcoin if you prefer.

You can’t compare the two things! That’s fucking ridiculous.

How is it ridiculous? They both accomplish the same thing (managing the transfer of value tokens). One has a lot of nice properties like decentralization, but is **nine orders of magnitude** less efficient, which is batshit insane.

It’s like you’re comparing the computing power of a languange with the computing power of an actual machine.

Bitcoin *is* a machine. A large, decentralized machine for processing financial transactions. Which is a task that a single Raspberry Pi can accomplish too (minus a bunch of neat features, but with better throughput and a similar database size).

Note that I'm not talking about *cryptocurrency as a whole*, or some abstract notion of Bitcoin. I'm talking about the Bitcoin network, *today*, as it exists, and in particular all the miners that are part of it.
