For the trial hashwall, the browser just does some heavy computations. I guess I should add a warning there, it's probably does have battery impact if you're using a phone for whatever reason.
I'll make a note on the UI elements. Honestly hadn't thought about the punycode usecase, good catch.

Yeah, I figured that out, but someone else might think you are trying mine some *coin or something. I am not sure if I would mind it if you did, but it would be good to tell up front what you are doing. It does seem to be a much better than recaptcha.
The fact that it works is good enough for me. I am going fiddle a little more before I sign up, but it looks like this is fills my needs.
