Just think how secure Bitcoin will be when we have to Dyson sphere the sun to do the "proof of waste". Uh I meant work. But if the work has value you could sell

Just think how secure Bitcoin will be when we have to Dyson sphere the sun to do the "proof of waste". Uh I meant work. But if the work has value you could sell it for on the side, then it reduces costs of attack, so waste as a feature. I like "proof of wait" for inflation rewards better :). The good news is, we can have other socially enforced consensus networks. (As all blockchain consensus is actually social.) So there's hope for real efficiency, it's just not on version 1 of blockchains. Caveat: I'm biased.
