Just to elaborate here. You are describing one implementation of a blockchain that provides a cryptocurrency. Blockchain is literally just another form of a database. It’s just that it can contain traits that would allow the database to be shared and distributed unlike typical databases. Currently there are some companies that are utilizing blockchain for their inventory systems. They aren’t using any more energy than they would with a typical system. They are just doing it to keep an unchanging record of past transactions which helps with fraud and loss prevention.
P.S. Money laundering using a system that is publicly distributed and has every transaction involving usd paired with an ID, social security number and enough pictures of your face to make a 3D model is genuinely idiotic.



Mentioning the hands. The one at the bottom left is just holding a phone and 100% nobody’s in this photo. Also kinda rude by they gave the random lady in the middle the shadow mustache.
