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 revenue numbers on there. Though no details on the traffic other than it peeked at 2,000 simultaneous users so that's hard to quantify with the data.

One big question actually is if you use the captcha system, is it actually effective at proving you are human?

Also, the short link one is a little stealthy. But overall it only delayed my experience by a couple seconds so I probably wouldn't care unless it happened very often.

I agree that there should be some sort of notification but other than that, I actually find this idea quite sympathetic. If you read my site, you can pay me by mining for me. It requires no extra effort on your part -- no credit card or micropayment login etc., and the longer you spend on my site, the more you pay. The exchange of value seems more clear cut that ads.

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 where you'd have the best results trying to mine cryptocurrencies), I would honestly prefer this over tracking cookies, obnoxious and intrusive ads, extra network connections, and all that crap. And I run an ad-blocker, so this will let you get some revenue while ad RPM will be 0. On my phone or laptop using battery power, you're not going to have any success mining and I'm not going to want this. (I also run an ad blocker on those, so...yeah).

I really like this. Not 100% sure how much a user can actually earn in say a 30 minute period but definitely going to try and add this as a form of monetisation in one of my sites and see how users respond.

I wish you could ask for money directly instead of inflicting the payment on me through my power bill...

Doesn't have to be your power bill ;) (e.i. public library, work)

If this is not clearly opt-in I wish those responsible for using it on their site a slow and painful death. Performance and bloat in browsers are a huge problem and having this constantly running in the background (without consent) is an absolute nightmare.

I have tons of sites opened 24/7. If yours happen to be loaded and you try to exploit my machines resources I will be quite pissed.

I'm also curious about the Captcha. It's a great idea, but what's to say that bots won't be able to run it as well?

Full 100% load on all CPU threads success ;)

Use of Monero (XMR) is an interesting choice. Monero is quickly being adopted as the coin of choice on dark net markets due to its builtin anonymity features. But dedicated third party-services such as escrow, multi-sig, etc have not kept pace with user demand. There seems to be an open window of opportunity for Monero centric contracts and payments.

This is definitely an interesting POC and makes an interesting case for why XMR might be ideally suited technically for web microtransactions. With the obvious caveats about hijacking browser performance being opt-in only that others have pointed out of course. Keep going!

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)

Browsers throttle not active tabs.

to earn 0.01 USD you need 1MH at the moment. In my browser I can generate 25H/S so about 44 days on one browser to generate 1$

2,112 users 30 minutes on your site

Or maybe just some great computers filling the hallowed halls.

That's fair.

I suppose a more polite version would run only when the tab is in focus. But as has been pointed out, this doesn't seem feasible because of the tiny amount of value generated so I think it's an interesting idea to explore more than anything else.
