I think this is hinting at something much deeper here. Something far more profound. Yea yea monetizing websites without add blocker. Don't get me wrong that is cool. But did he just say practical micro-payments!? By doing proof of work for the benefit of someone else you can send small amounts of value to anyone you want for any reason you want for ~0 transaction cost. The scope of this surely must be greater than the article alludes to.
It's far from ~0 transaction cost, they skim 30% of the hashes.
I'm talking about a grander scope and you are drilling down on one specific implementation of the idea by one specific firm. Kind of going in the opposite direction of what I had in mind there.
Well excuse me to burst your bubble, what grander scope implementation are you talking about? Oh wait you're just dreaming. You think it's easy and cheap to distribute work tasks across millions of clients and take a beating from millions of hashes submitted each second?
