I looked through the documentation and I've come across a couple sites using this already.
Genuine question: why not leverage the proof-of-work challenge literally into mining that generates some revenue for a website? Not a new idea, but when I looked at the docs it didn't seem like this challenge was tied to any monetary coin value.
This is coming from someone who is NOT a big crypto person, but it strikes me that this would be a much better way to monetize organic high quality content in this day and age. Basically the idea that Brave browser started with, meeting it's moment.
I'm sure Xe has already considered this. Do they have a blog post about this anywhere?
