This is much better than I thought it would be. I wonder how many commentors actually tried the demos. Two of the three ways I could see on the page to use it involve delaying the user slightly (while doing a proof of work) after a checkbox or link is clicked. Not constantly running in the background. The one that does constantly run requires clicking a play button, which seems "opt-in" to me. They also have some rev…

> This is much better than I thought it would be. I wonder how many commentors actually tried the demos. In what way is it better than your expectations? (For me, it behaved as expected: immediately maxed my CPU load and spun up the fan)

My expectations were pretty low. I was expecting it to be doing something with the user's consent or using some sort of UX anti-pattern to trick the user into doing it. I was pleasantly surprised.

As far as performance. It didn't do enough to spin up my fan. My CPU only went to 30% (inclusive of all the other apps I have running (using Chrome on OS X).

I was under the impression most browser limit how much CPU the Javascript thread can use because of the good old days when writing a tight infinitely loop in Javascript could freeze someone's computer.

I was playing with my own Proof-of-work a couple years ago with a pause every X ms so we don't lock the browser while doing the calculations. If someone want's a simple introduction to basic hashing on the clientside here is a simple implementation: https://gist.github.com/Xeoncross/d5a9482e5231db62fb87

coin-hive/Monero would solve a lot of issues with simple MD5/SHA1 implementations like mine (like bot GPU's blowing through any kind of hashcash challenge).

2-5 cents per 24 hours of a user being on your site seems like a bad tradeoff for the downsides.

2-5 cents per 24 hours seems fairly equivalent to ads, actually. Ad CPM (or more appropriately, RPM) seems to average somewhere around $2.50 (that's per thousand impressions). If these thousand users were on the site for 24 hours, that would be $20-$50, a more realistic scenario would be users on a site for a few minutes, generating comparable revenue to ad impressions. On my desktop (which, not coincidentally, is wh…

Your comparison doesn't take into account that 24 hours here means the user had to keep your tab open for 24 hours to make 2-5 cents.

That's nothing like ads.

This is a really good idea, but I'm not convinced of the Crypto mining side of it. Why not just build a system that allows customers to buy and sell CPU resources, in a similar way to how a ad network allows customers to buy and sell ads?

That exists (for crypto mining). https://www.nicehash.com/

Cant imagine that anyone blocking ads wouldnt also block this

Why? It isn't an ad. Most users block ads because they find ads annoying, not because of script bloat.

I don't know about everybody else but script bloat, and its implications for performance in generally and scrolling smoothness in particular, are the main reason that I block ads - the visual distraction is a secondary factor.

I guess <6 cents per day, let me know if that was right or not.

I will !

And post / re-post: "I tried that crypto-coin ad alternative thing and you won't believe these results!" ;-)
